Do you want to quickly and inexpensively build a garage or utility room on your site? I will tell you how to make a lightweight frameless hangar with your own hands using the minimum amount of building materials. You will also learn about all the positive and negative qualities of arched hangars.

The principle of manufacturing frameless hangars

A frameless arched hangar is a lightweight, pre-fabricated roofed structure, which is built from individual spans of a semicircular shape in the form of an arch. The walls and ceiling of the hangar are made in the form of a single self-supporting structure from a corrugated metal profile.

The technology for the construction of frameless hangars is as follows:

1. Arrangement of the foundation. On the selected plot of land, planning work is carried out, and then a shallowly buried strip foundation... Embedded structures for the installation of arched spans are attached to the reinforcing frame of the foundation;
2. Spans manufacturing. Each element of the arch span is made individually from galvanized steel coils directly on construction site... Then they are fastened on the ground into solid modules of 3-4 pcs. For these works, several types of special machines are used;
3. Installation of arched spans. The assembled modules are installed one at a time on the foundation and attached to the embedded structures with bolts. After that, they are connected to each other along the entire length of the profile using a folding machine;
4. Installation of end walls. The back wall is usually sewn up with a straight galvanized profile. A supporting frame for the gate is installed in the opening of the front wall. The sides of the front wall are also sewn up with a profile, and the gate wings are hung on the vertical posts of the frame;
5. Sealing and insulation. The joints of the arched spans and the foundation in the lower part are treated with bituminous waterproofing and poured with concrete mortar. If necessary, the finished hangar is insulated using one of the methods described below.

Along with the described manufacturing technology, there are demountable hangar models. In them, all arched sections consist of several prefabricated elements. They are assembled on site and then bolted together.

Application features

Most often, hangars are equipped with production or storage facilities, covered markets and parking lots, as well as cultural or sports facilities (stadium, skating rink, tennis courts, etc.).

In a private household, a light metal hangar can also be used:

• Garage- the most common option. Moreover, it can be used not only for a car, but also for a truck or large agricultural machinery;
• Commercial premises. For those who are engaged entrepreneurial activity, in the hangar you can organize own production... This will allow you to place it closer to home, and save on the rental of production space;
• Attic floors. Frameless arched technology allows in a short time to build on an insulated attic floor above any house with a flat roof. Such a structure is lightweight, therefore it does not exert a significant load on the building itself;
• Pig farm or barn. Private farmers can adapt it as a chicken coop, cowshed or pigsty, as well as a seasonal storage for crops of grain, vegetables or fruits;
• Rest and leisure. In regions with cold climates and long snowy winters, inside the insulated hangar, you can equip a playground or playground or even an indoor pool.

If we compare frame hangars and frameless arched structures, then the latter have more positive qualities in terms of construction and further operation:

Advantages:

1. High strength. Due to the ribbed profile of the arched spans, such structures have high rigidity and good self-supporting capacity, so they do not require an additional frame. Despite the apparent lightness, they have the following technical characteristics:

• Maximum span width - 30 m;
• The maximum hangar length is not limited;
• The maximum permissible wind speed is 200 km / h;
• Operating temperature range - from -50 ° C to +50 ° C.

1. Durability. Due to the galvanized metal coating, the absence of through mounting holes and the sealed seam connection of the arched segments, such structures do not require additional waterproofing, and their settlement period operation is at least 30 years;
2. Easy to assemble and dismantle... Frameless hangars are lightweight, so they can be installed on a shallow strip foundation in any type of soil. Small spans can be manually installed by several people. If necessary, such a structure can be easily disassembled.
3. Logistics and construction speed... All arched elements are manufactured directly on site. This significantly reduces the cost of delivering building materials. In time, frameless arched hangars are being erected several times faster than any other structures of this size;
4. Energy efficiency... If we compare rooms of the same area with rectangular and arched spans, then the arched one always has a smaller internal volume. This helps reduce heating and air conditioning costs.

Disadvantages:

1. The presence of dead zones. The semi-cylindrical shape of the vault is not very convenient for production or storage facilities with large industrial equipment or with a rack storage system. In such cases, unused free space is formed at the edges of the half-cylinder.
2. High vault height... The height of the arch in frameless structures is usually equal to 40-50% of the diameter of the conditional cylinder. This means that with a hangar width of 24 m, its height at the midpoint will be 10-12 m. In most cases, such a height is not needed, moreover, it will lead to unnecessary heat losses.

If necessary, in arched hangars, it is possible to install dormers, opening sashes for ventilation, additional or wickets, as well as a heating or air conditioning system.

Construction of a frameless hangar

Stage 1: preparation of tools, equipment and materials

In addition to the usual set of locksmith and garden tools, you will need special equipment to work. I must say right away that the price of all these machines is very big, so you don't need to buy them, but it is better to rent them for a few days.

Tools and equipment:

Illustration	Set of tools
	Equipment for working with a profile: Roll forming machine- allows to make straight profiles of unlimited length from galvanized steel coil; Corrugated rolling machine(pictured on the left) - designed for rolling a straight profile along a given radius. He also creates corrugated folds on the metal surface, which increase the rigidity of the profile; Fencing machine- designed to connect two arched segments together. When rolling along the junction of two profiles, it folds the edges of the metal twice and forms a sealed folded joint.
	Foundation work tools: Electric concrete mixer or construction mixer; Two metal buckets of the same volume; Shovel and bayonet shovel; Garden or construction wheelbarrow; Trowel or trowel; Hook for tying reinforcement; Building level; Submersible vibrator; Nails 50-100 mm long.
	Installation tools: Electric rock drill with a set of drills; Electric drill with a set of drills; Grinder with discs for metal; Electric arc welding machine with a protective mask and electrodes with a diameter of 3-4 mm; A set of wrenches from 10 to 22 mm; Heavy hammer; Sledgehammer; Crowbar or pry bar about 1 m long; Construction cord and rope plumb line.

Materials:

Illustration	Description of work
	Components of the concrete solution: Portland cement grade M400 or M500; Clean quarry or river sand; Granite crushed stone with a particle size of 25-35 mm; Cold tap water.
	Steel rolled products: Galvanized sheet steel with a thickness of 0.8-1.5 mm in rolls of 100-250 m; Profile pipe or channel with a cross section of 60x60 - 100x100 mm for the bearing frame of the gate; Corner or profile pipe with a cross section of 60x30 mm for the manufacture of gate leaves; Steel corner with section 80x80 for embedded mounting brackets; Reinforcing bar with a diameter of 8-12 mm for foundation reinforcement.
	Fasteners and auxiliary materials: Galvanized bolts with a diameter of 8-12 mm and a length of 40-100 mm; Galvanized nuts and wide body washers of the same diameters; Steel garage hinges for swing gates; Rubber-bitumen mastic for waterproofing coating; Planks or trimmings of lumber for the manufacture of formwork.

Stage 2: arrangement of the foundation

During the construction of prefabricated hangars, embedded brackets are poured into the formwork along with the foundation. Otherwise, the manufacture of a shallowly buried strip foundation is carried out according to the classical scheme:

Illustration	Description of work
	Planning works: On a plot of land, remove the fertile soil layer together with plant roots to a depth of 100-150 mm; Use pegs and a construction cord to mark out; Dig a trench 500-600 mm wide and 700-800 mm deep; In the corners and along the entire perimeter of the trench, dig pits 1000 mm deep at a distance of 1000-1500 mm from each other; Pour a layer of sand 100 mm thick into each pit on the bottom.
	Installation of mortgages: Embedded structures must be welded in the form of a lattice from a reinforcing bar with a diameter of 12 mm; They must be installed in the pits so that the rods protrude 60-100 mm above the upper plane of the foundation. After installation, fill each pit with concrete to the bottom of the trench.
	Installation of a reinforcing belt: Compact the soil at the bottom of the pit and fill up a sand cushion with a thickness of 100-200 mm; Weld a longitudinal reinforcing belt welded from the same reinforcing bar in the form of a lattice to the mortgages; Install the formwork at the height of the foundation on both sides of the trench.
	Pouring concrete: Pour concrete mortar into the formwork in several layers; To compact and remove air bubbles, the entire thickness of the poured concrete must be processed with a submersible vibrator.
	Dismantling the formwork: The formwork can be removed a week after pouring; Further work can be performed only after the final maturation of the concrete; This may take 14 to 28 days.
	Corner bracket: An 80x80 mm corner must be welded to the reinforcement bars protruding from the foundation along the entire length of the foundation; The lower part of each arched segment will be attached to it; Below, on the left side of the photo, you can see the base plate with pins; It is designed to mount the vertical goal post.

When erecting small hangars, embedded structures may not be immediately poured into the foundation. In this case, the brackets from the corner are attached with anchor bolts to the upper plane of the foundation after solidification.

Stage 3: making arched sections

When installing frameless arched hangars manually, each arched profile is mounted separately. If the installation is carried out using a crane, then to speed up the work, they are assembled from separate sections of 3-5 profiles in each. The manufacture of such sections is carried out in three stages:

Illustration	Description of work
	Size calculation: The entire roof of one hangar is assembled from the same type of profiles. They must have the same dimensions and bend radius; The width and shape of the cross-section of the profile is set by the configuration of the profiling machine of the machine; The length of the profile is calculated depending on the width of the hangar, and is determined by the formula: L = S / 2x2.85, where: L is the length of the workpiece, mm; S - hangar width, mm. For example, you need to determine the length of an arched profile for a hangar with a width of 18000 mm. According to the above formula, we get 18000 / 2x2.85 = 25650 mm.
	Step 1: Profiling the galvanized sheet: The roll forming machine works in automatic mode; For the manufacture of profiles, you need to put a galvanized roll on the feed drum, and fill the beginning of the roll into the machine's receiving mechanism; On the control panel, set required parameters(length, width); After starting, the machine will automatically give the profile the desired shape and cut the workpieces to the specified length.
	Stage 2: rolling the profile: To give the profile an arched shape, it must be rolled on a second machine; One end of the workpiece must be tucked into the rolling mechanism; On the control panel, set the thickness of the metal and the radius of the arc; After turning on the machine, a corrugated profile of the correct arcuate shape will come out from the back side.
	Step 3: Folding the arch section: All profiles are connected to each other using a flanging machine; To do this, they need to be superimposed on each other, and the two side edges must be precisely aligned; So that they do not move, they must be fixed in several places with lever clamps or clamps; Place the edges of the metal between the folding rollers and start the folding machine; Then it will go on its own, and will leave behind a strong and sealed folded joint.

Stage 4: Assembling the hangar

For the installation of arched spans up to 16 meters wide and up to 7 meters high, mobile collapsible scaffolding can be used. It is more convenient to build hangars with a height of more than 8 meters using a crane or telescopic lift:

Illustration	Description of work
	Rigging works: Before lifting, the arched section must be fixed to the horizontal traverse at two points; For this it is convenient to use special cam clamps; They are attached to the folded flange, and allow you to securely hold the section without damaging the protective zinc coating.
	Fastening the profile to the foundation: It is more convenient to assemble the hangar from the front or rear end; The arched segment must be installed so that it descends from both sides to the foundation outside the steel corner; From the inside of the hangar, weld steel plates with holes to the corner; Each plate must be welded against the convex part of the profile; After the final installation and adjustment of the segment, counter holes must be drilled in the profile; Fix each arched segment to the foundation on both sides using bolts with nuts and widened washers. The bottom photo shows a view from the inside of the hangar.
	Connection of profiles: After installing two adjacent arched segments, they need to be fastened together with a folded joint; To do this, the joining ends of two adjacent profiles must be tucked into the rollers of the flanging machine; After making sure that both arches are in the correct position, you need to turn on the machine; Further, it will go along the radius profile on its own, leaving a folded seam behind; After bordering the entire arched section, the machine must be met on the other side of the hangar, turn off the power and remove it from the profile; Thus, you need to connect all the radius profiles in the hangar roof.
	Gate installation: The supporting frame for the gate must be made of a profiled pipe or channel of a large cross-section, since it will take up the entire load from the weight of the leaves; It is attached to the base of the foundation with several threaded rods; To make the frame of the doors themselves, you need to use a smaller pipe; The outside of the sash can be sewn up with galvanized profile sheet.
	Front and rear wall mounting: The same galvanized steel profile is used for covering the front and rear walls of hangars; After manufacturing, it is not rolled on a corrugated rolling machine, therefore it remains straight; The vertical profiles in the lower part are bolted to the corner on the foundation; In the upper part, they go into the cavity of the arched profile, and are also bolted to it; All vertical profiles are connected to each other using a flanging machine.
	Bottom sealing: Coat the lower part of the arched profiles and all metal elements at a height of 500 mm from the foundation with heated rubber-bitumen mastic; On the outside of the foundation, install a wooden formwork along the entire perimeter; Pour concrete solution into the space between the formwork and the hangar body to a height of 300-400 mm from the foundation; One week after pouring, the formwork can be removed.

Stage 5: Wall insulation

Below is a brief instruction on insulating a frameless metal hangar. This can be done in one of the three ways described:

Illustration	Description of work
	Method 1: double casing with mineral wool insulation. This method is considered the most effective, but at the same time more expensive: In this case, one hangar is built first; Insulation is placed inside the arched profile from the outside; A vapor barrier is laid on top of it; After that, another outer body is erected from above from the same arched profiles.
	Method 2: insulation with mineral wool and lining with profiled sheet. This method can be used to insulate any already built hangar: As in the first case, first, mineral wool slabs are laid on the outside of the arched segments; From above it is covered with a vapor barrier membrane; A crate made of thick plywood is mounted on top of it; An outer covering made of galvanized profile sheet is attached to the crate.
	Method 3: internal spraying with polyurethane foam. This option is suitable for any hangar. Its main advantage is protection against the formation of condensation on the inner walls: Polyurethane emulsion is applied to the inner walls in several layers using a special spray gun; Under the influence of natural air humidity, the polymer composition foams and solidifies; After polymerization, a foamed polyurethane coating with a dense outer layer is formed on the surface; It has low thermal conductivity and good resistance to moisture and temperature changes.

Polyurethane foam degrades when exposed to ultraviolet radiation, so it can only be used for internal thermal insulation.

Conclusion

Now you know what a hangar is and how it is built. Installation will be much cheaper and faster than constructing any other building of the same size. I recommend watching the video in this article, and all your questions can be discussed in the comments.

Experts of the Ukrainian agricultural market believe that in the coming years there will be a surge in demand for grain storage from small and medium-sized farms. “Most of the companies with a land bank of more than 5 thousand hectares have their own elevators. The segment of large elevators for large enterprises is saturated. Therefore, the segment of small and medium-sized grain storage facilities is currently developing most actively, ”said Andrey Kupchenko, grain markets analyst at APK-Inform Agency (). Namely, frameless technologies are perfect for the construction of floor grain storage facilities.

However, many farmers have heard that frameless structures are unreliable and can collapse from strong winds and excessive snow loads. This article contains information that will help the future owner of a frameless structure make an informed choice, which will help to avoid troubles and losses in the future. You will learn about the types of arched hangars and stages of construction, while designers and builders will talk about the pitfalls of frameless construction. We will also analyze the court case on the collapse of a frameless storage hangar in the Belgorod region. finished products, the construction and operation of which has become a vivid example of unprofessionalism, greed and carelessness!

General information about frameless arched hangars

Frameless arched hangars are a type of pre-fabricated buildings, which are a single self-supporting structure of an arched shape made of rolled galvanized or painted steel with a thickness of 0.8-1.5 mm (see "").

• The arch width can be from 3 to 30 m,
• hangar height depends on the span of the arch,
• the length of the building can be any.

There are 3 basic forms of frameless hangar arches. The designer of each of the forms can be modified depending on the specific needs of the agricultural enterprise (see "").

In agriculture, several design solutions for frameless structures are used:

1. Usually arches are installed on a strip or slab foundation.
2. Also, steel structures can be installed on a base, which can serve as walls of an existing building, concrete blocks or columnar foundation any height.

For example, if the structure of the hangar is designed taking into account the load of grain crops on the walls with a height of 2.5 m, then the arched hangar measuring 15x30 m (450 sq. M) can accommodate 1,000 tons of wheat.

A frameless hangar with an area of ​​1 thousand square meters accommodates:

• 3 thousand tons of potatoes
• 2 thousand tons of wheat
• 1.2 thousand tons of sunflower
• a pigsty for 500 heads can also be accommodated

The arched shape of the premises allows very efficient use of space when storing bulk materials. However, future owners of granaries should definitely know that it is under no circumstances to put grain on the steel parts of the structure!

Scope of application of frameless hangars in agriculture:

• Grain and vegetable storage
• Feed warehouses
• Livestock premises
• Production buildings
• Awnings
• Hangars for special equipment and repair shops
• Administrative buildings

Frameless hangars are manufactured directly at the construction site using special mobile complexes. Such complexes produce profiling and corrugation of coiled steel while simultaneously giving the required radius (see ""). Subsequently, the arched element is combined into blocks and connected in the design position with a folding (folding) machine. Then the arched blocks are lifted with a crane and installed on a previously prepared foundation and fixed by spot welding or bolts to the embedded parts of the foundation. Watertightness and tightness of seam joints is an advantage over traditional construction methods and can significantly reduce operating costs.

In separate blocks, we will analyze the court case on the collapse of the arched hangar (see "Case No. А08-7248 / 2013")

The most interesting excerpts from this judicial trial can be found.

Advantages of frameless arched hangars

Frameless technology makes it possible to build hangars in record time. It will take 10-15 days to build an arch for a grain warehouse with an area of ​​1 thousand square meters. Artem Bilyk, head of the Engineering Center of the Ukrainian Center for Steel Construction (USSS), noted that this technology makes it possible to construct not only arched structures, but also temporary circular granaries in an incredibly fast time: literally in 3-4 days it is possible to build storage facilities for 2-3 thousand cubic meters. tons of grain, which is successfully used by farmers in the United States and other countries.

Also among the advantages of frameless construction are:

• Combination of supporting and enclosing structures
• Span up to 30 m and the absence of internal columns or trusses, which allows full use of the entire internal area of ​​the room
• Production directly at the construction site, which minimizes transport costs
• One compact raw material type - sheet steel coil
• Possibility of fast and effective thermal insulation by spraying up to 70 mm of polyurethane foam
• Seam tightness and minimum operating costs
• Various shapes, adaptability for purpose, the possibility of inserting windows and gates

In agriculture, frameless hangars are successfully used as floor grain silos, which have a number of advantages over silo elevators. Firstly, the floor storage can be used both for storing grain and for other purposes, while the silo can only be used for storing grain. In addition, corn, soybeans and other crops are better stored in the floor warehouse, there is less height for the grain to fall during loading, which prevents injury. Secondly, there is more condensate in the silos, as it is metal. In floor-standing warehouses, metal does not come into contact. This often uses internal retaining structures that separate the interaction of the grain with the enclosing structure.

Prices for frameless arched hangars and granaries

But still, the main advantage of arched structures is the price of frameless hangars. Usually companies declare that the cost of erecting arched hangars is about 2-2.5 times less than that of frame structures (see "").

Savings in the construction of arched hangars is achieved due to:

• lack of a frame, which reduces the metal consumption of the project;
• use of lightweight (cheaper) foundations, which, moreover, the customer can build on their own;
• minimum logistics costs.

However, the cost of construction for different companies operating in the frameless construction market may differ by 5 times (see ""). Having monitored the Internet at the beginning of summer 2017, I found that the minimum price for the construction of arched hangars was 400 UAH / sq.m. True, it is worth noting that the companies do not indicate what is included in this price - only an arch without a foundation and a gate, what kind of metal is used, etc. I found a more or less intelligible offer for May 2017 on the website of the Industrial Systems company, where the construction of a frameless grain warehouse with an area of ​​1.08 thousand square meters (60x18 m) will cost about UAH 2.15 million, or almost 2 thousand UAH / sq.m (see "").

Quite often, the price of a frameless structure, announced on the websites of companies and at preliminary negotiations, increases over time for various reasons. The expert warns: "Some contractors are cunning, initially declaring a low price per square meter of the future hangar, then including additional costs for the rental of lifting equipment, delivery of equipment and materials, accommodation and meals for workers, etc."

According to operators

For example, the cost of renting cars, crane work, crew travel to the construction site, security can be up to 15% of the total cost of construction. More detailed information about the cost of building frameless arched hangars and the prices of the materials necessary for this is located.

Floor grain silos, built using frameless technology, outperform silo elevators. For example, the construction of a silo elevator will cost at least 3 times more (based on the price for 1 ton of storage; see "Arithmetic for building an elevator. How to build cheaper?") Than a ready-made floor warehouse with mechanization, built using frameless technology, with conveyors and all the necessary equipment.

A non-mechanized floor-type grain warehouse, the design of which does not provide for the presence of transport mechanisms, with a gallery without conveyors in any design, will cost within $ 13-14 per cubic meter of storage. According to the latest estimates, a semi-mechanized grain warehouse, which has added top loading, upper conveyors, towers, lighting, increases the price of the grain warehouse by another $ 4-5 per cubic meter of storage. If you also install unloading, then the price of a floor grain storage will increase by another $ 4-5, depending on the task. Experts noted that the price of a mechanized grain storage without thermometry will cost about $ 25 per cubic meter of stored products. The maximum is a grain storage with aeration, with transport, with temperature and humidity sensors, everything that you can think of - the cost of such a grain storage will be about $ 30 per cubic meter of stored products. A set of metal structures for a silo without a foundation and without installation will cost at least $ 60 per cubic meter of stored products (see "").

Source: "Industrial Systems"

Ruslan Dashkevich, Commercial Director of Industrial Systems LLC, told the Grain Storage and Processing magazine (No. 9 for 2016) that when building from scratch, the cost per cubic meter of storage of a non-mechanized warehouse and a mechanized warehouse is the same. The difference is that a mechanized warehouse requires more investment at a time. That is, square meters, if you count, will be more expensive, but the price for a storage cube will be the same. An agricultural producer can choose for himself: to build 1000 square meters of mechanized warehouse or build 2000 square meters of non-mechanized one (see ""). It will be the same money and the same capacity. Mechanized warehouses can accommodate more products per square meter. It makes no sense to do mechanization with a small load per square meter. “A frameless hangar, built simply on a foundation, on a reinforced concrete wall, can be mechanized in the future, but it is unprofitable and expensive (see“ ”),” Ruslan Dashkevich noted.

Disadvantages of frameless arched hangars

A significant problem of frameless construction in Ukraine is a very vague regulatory and technical base. Only 05.05.2016 in the Ministry of Agrarian Policy was signed a Decree on the inclusion of prefabricated hangars, developed in accordance with TU U 45.6-32821424-001: 2012 (developed by Industrial Systems LLC), in the State Register of technical means for agro-industrial complex Ukraine (). Unfortunately, it was not possible to find a description of this TU on the Internet (see Russian TU 5283-147-02494680-2004), and representatives of the Industrial Systems company, referring to their busyness, did not find time to answer the questions that were poisoned to them in the preparation of this articles.

“When choosing a company engaged in the construction of frameless hangars, the customer should pay attention to whether the contractor has documentation for the products - hangars - TU, Enterprise Standard and its level of elaboration. For example, in Russia, only a few companies have technical specifications developed design organizations", - said the expert.

Many experts complain about the lack of reliable and proven miscalculations of the stability of such structures (see ""). Igor Khoroshilov, a design engineer at Starplast, warns that in a classical calculation, a frameless structure should collapse in the first year of operation. But they are! The reason is that due to the corrugation of the profile, the laws of section reduction change, the stability of the section to the load increases, and the classical calculation is not applicable. I heard that there were attempts to calculate it "from scratch", but the results were still negative - the building with such arch thicknesses should have collapsed, if we take into account the snow loads generally accepted for our climatic zone. But here they are. They are destroyed only when violations become egregious: the thickness is less than 1.2 mm, the span is more than 24 m, the length of the building is more than 70 m. ", - added Igor Khoroshilov (see" ").

Deputy general director on the scientific and technical policy of LLC "Ukrinstalkon named after V.M. Shimanovsky", Vladimir Adrianov noted that frameless arched structures are unstable and require special attention to ensure their safety, reliability and, preferably, durability. Therefore, the customer must:

• involve a company (enterprise) of a supplier of structures with sufficient experience and, preferably, with the provision of a certificate (declaration) for compliance with normative and technical documentation (NTD), according to which the structures will be manufactured;
• installation of structures is commissioned by a specialized construction organization with the necessary work experience;
• ensure the operation of frameless arched hangars made of folded metal structures, taking into account the requirements of the current standard of Ukraine for the inspection of buildings and structures made of metal structures.

The customer should pay attention to the qualifications and experience of the companies and their construction teams. Director of the company "Angaryugstroy" Andrey Zdot noticed that now even farms buy themselves roll forming machines and try to build arched hangars. Then some time comes and they call us with a proposal to sell these machines, as they begin to understand that the construction of frameless structures is, first of all, specialists and practitioners.

V construction company"Iveco-Bud", which is engaged in the construction of frame structures, believe that frameless arched structures are not repairable in case of any damage to their self-supporting surface. After all, no one canceled unpredictable external loads and shrinkage of soil or light foundation. The frameless structure is assembled into a single whole during the installation process and can be replaced, if necessary, also only as a whole. However, specialists from companies building frameless structures said that arches are quite amenable to repair and galvanized metal can be cut, sewn, make an opening, etc.

Valeriy Dryuk, the deputy general director of the company "Sunward-Ukraine", confidently declares that when operated in a non-aggressive or slightly aggressive environment, the frameless arched building will serve for more than 30 years. If necessary, the building can be dismantled and erected in a more convenient place or lengthened, and in case of mechanical damage to the metal structures, it can be replaced by elements.

The shape of the arch does not always allow full use of the internal volume of the room when it comes to storing bulk or bulk objects.

Prefabricated premises of solid cubic capacity are always in demand in the construction market, because with the help of such structures it is possible to solve many problems in various areas of business. Today, frame and frameless buildings have gained the greatest popularity, which boast an impressive list of advantages (however, of course, along with this, there are a number of disadvantages inherent in these structures). Below we will try to analyze in detail the pros and cons of building such premises, and we will also voice some tips that will help make the construction of frame and frameless hangars faster and more economical.

Spectrum of application of structures

Frameless and frame hangars have found a fairly wide scope of application in modern world... They are used almost everywhere in all areas, however, these designs are still most widespread in:

• Agriculture. Such hangars are most often used as grain, fruit or vegetable storage facilities. Also, such structures are often ordered in animal husbandry - the same prefabricated frameless structures are the best fit for placing cattle farms.
• Sports infrastructure. Indoor spaces are used to equip small sports complexes or stadiums for futsal, basketball, handball, volleyball and other team sports.
• Entertainment area. Prefabricated structures are ideal for the construction of nightclubs, amusement areas, etc.

Frame or frameless hangars: pricing policy

The final cost of structures directly depends on the amount of material used, filling the base and the duration of the work performed. When building frameless hangars:

• There is an order of magnitude less metal sheets and products used, since there is no need to equip a durable metal frame.
• A light foundation is poured, which, as a rule, lies only along the base of the building. This nuance leads to significant savings in the purchase of cement.
• Construction takes place several times faster than in the case of frame structures.

All of the above points indicate that the construction of frameless hangars will cost the customer less work than the construction of a new frame object.

IT'S IMPORTANT TO KNOW!

As of the beginning of 2018, the average cost of a frameless hangar with an area of ​​700 sq. M. ranged from 2.5 to 3 million rubles. The construction of frame structures was approximately one and a half times more expensive.

Construction speed of frame and frameless hangars

The construction of frame structures, of course, begins with the pouring of a powerful heavy foundation that can withstand the load of a building, the walls of which are composed of many metal elements. A similar procedure, as a rule, takes at least 15 days in favorable weather (during constant rains or high humidity, pouring the foundation can take a month). After the concrete has gained the necessary margin of safety, the metal frame is assembled, on which the metal sheathing is added upon completion of construction.

The construction of frameless premises takes place in 2 stages. At the first of them, specialists assemble and prepare an arched structure for installation, at the second, they fix it on a pre-poured light foundation. Also allows you to reduce the time for the construction of frameless hangars functional features elements of the arch - each of them is a fencing and bearing part at the same time.

All these circumstances give us the right to draw the following conclusion: the construction of frameless structures is carried out one and a half to two times faster than their frame counterparts.

IT'S IMPORTANT TO KNOW!

On average, the construction time for frameless structures is from 20 to 30 days. Basically, they depend on the configuration of the future structure and its modernization with additional elements.

Reliability and durability parameters of structures

Naturally, in terms of reliability and durability, frame structures are more preferable. Due to the massive foundation, wide partitions and other elements, they are much more stable than frameless buildings. However, these characteristics also determine the annual significant costs for maintaining the normal state of the hangar. These costs include permanent care:

1. Behind the foundation of the building. If corrosion or any other defect occurs in the base, this can lead to a violation of the geometry of the entire structure and significant deformation of the metal sheets used for wall cladding.
2. Behind a metal frame and wall cladding. The fact is that often to reduce the pressure on the foundation, the builders of frame hangars reduce the weight of the walls due to thinner metal sheets (often corrugated board with a thickness of no more than 0.5 millimeters is used). Naturally, this makes the walls of the room very sensitive to bad weather - without the prevention of corrosion and rust, after a year of use, under the influence of snow and rain, metal structures can turn into dust.

As for the service life of the premises, the following figures should be given here:

• Frame constructions can be used for 70-90 years.
• For frameless hangars, the maximum life span is set at around 50-70 years.

The nuances of construction and the main differences between frame and frameless hangars

So, summarizing the above, we can name the main differences in the construction and operation of frame and frameless structures:

1. Different types foundation. Frame structures require a more powerful base.
2. Increased use of metal elements in the construction of frame hangars. First of all, they are needed to equip the frame of the entire building.
3. Frame structures require much more attention than their frameless counterparts. It is possible to maintain such premises in working order only under the condition of constant prevention of wall and roof destruction, as well as regular inspection of the foundation for integrity.

IT'S IMPORTANT TO KNOW!

For frameless hangars, a strip foundation is best suited, which is poured along the perimeter of the future building. According to experts, such a base is able to withstand the load of the structure, and also provides an opportunity to save even more on construction.

Summing up: the main advantages and disadvantages of frame and frameless hangars

So, the main advantages of frame hangars include:

• Durability (service life reaches 90 years).
• Reliability.
• Resistance to mechanical damage.

Along with that, such premises have a number of disadvantages, namely:

• Constant maintenance of the metal cladding and frame of the building, as well as its foundation.
• High cost.
• Relatively long construction period.

The advantages of frameless construction are:

• The cheapness of construction.
• The speed of construction.
• Possibilities for high-speed modernization of the building.
• Ease of care.

The main disadvantages are:

• Less than that of the frame counterparts, the service life.
• Insufficient, according to some experts, indicators of stability, especially when used in extreme climatic conditions.

Specificity of the technological process

Arched construction of structures in Moscow and the Moscow region includes several stages. The corrugated galvanized profile, from which the walls and roofs of buildings are made, is formed from steel sheet on special equipment right at the construction site. To fasten the segments together, a folding method is used, which guarantees high strength and absolute tightness of the joint.

The foundation consists of screw piles and a metal corner. Screw piles proved to be excellent on different soils at any time of the year. If necessary, the walls of the hangar are insulated with a layer of high-quality mineral wool. High tightness of folded joints reliably protects everything inside the building.
