Welding trusses for a canopy from profile pipes. How to make a canopy from a profile pipe with your own hands Selecting a profile pipe for a canopy

Modern rolled metal products offer their consumers a variety of products, among which profile pipes stand out. It is used everywhere in private construction, for example, for the frame of an object on a personal plot. The design option in this case gains strength and durability incomparable to wood. The advantages and disadvantages, as well as how to make a metal frame for a canopy from profile pipes, are described below.

Steel profile pipes - characteristics and advantages

A special feature of this metallurgy product is its shape - a metal profile pipe, usually square, oval or rectangular, hollow inside. Due to this, the weight of the prefabricated frame is lightened, which is one of the advantages. Further:

Metal products have one drawback - corrosion. However, it can be easily prevented if the structure is coated with an appropriate composition or decorative red lead. When storing, it is important to lubricate the future frame with grease.

In order for the canopy frame made from a profile pipe to be reliable, its components should be selected correctly. Rolled metal products come in multiple parameters - from 20 to 110 mm in wall width and thickness from 3 to 8 mm.

For a country canopy, they do not use impressive sizes. In a small structure - 5 * 5 * 2.5 m, intended for parking a car or recreation area, the metal profile meets the following conditions:

1. The size of the pipes for the racks and the top trim will be 80*80 mm. Metal “heels” are placed under the racks. They will provide even greater stability to the frame and there will be no need to bury or concrete the supports.
2. To create an arch and assemble trusses – 40*20 mm. This section is amenable to mechanical bending, but if there is no experience, it is better to use factory-made products to create arched openings.

The thickness of the walls can be selected depending on the purpose of the structure - from 6 to 12 mm, the frame will have a strength comparable to reinforced concrete products.

Assembling a frame for a country canopy with your own hands

Any design requires precise design and calculations. This rule cannot be avoided by a canopy frame made from a profile pipe. It’s easy to assemble it with your own hands, even without special knowledge, but you should entrust the drafting and drawing to professionals.

In addition, in some regions, such a structure, especially one directly related to the house, requires official permission. This needs to be taken care of right away. Next, you should prepare or purchase the following tools:

1. Grinder with diamond blades for metal.
2. Drill with pobedite drill bits.
3. A portable or stationary welding machine with sufficiently long cables. Naturally, the station must be powered from an appropriate source.

The home handyman will need special protective clothing, glasses, and the ability to handle the tools described. Otherwise, you should purchase a ready-made canopy or choose a different material over a pipe.

Metal frame calculation

First of all, the profile frame must take into account the following nuances: the load of natural factors - rain, snow, wind. This data is available in architectural departments and design offices.

You can independently calculate the metal frame of a canopy, but this must be done before purchasing a profile pipe, so as not to make a mistake with the thickness of the walls and the width of the product. In general, it is better to entrust a responsible task to a designer - the price justifies the work.

Choosing a canopy option

Actually, here the choice is limited only by the skill of the home craftsman - giving the shape of an arch or an asymmetric bend will not be difficult, but it will require the ability to bend pipes in the chosen direction. One of the simplest is the design of a lean-to canopy.

The rafter system does not require any bends, and attaching polycarbonate to this form is as easy as shelling pears. You should also take into account the purpose of the canopy - straight roofs allow light and heat to pass through, while pitched roofs, on the contrary, reflect the sun's rays and the temperature inside will be optimal for relaxing or parking a car.

Stages of work

There are several of them: site preparation, foundation design, frame assembly. To ensure that the future canopy does not disappoint the owners, you should adhere to the details of the instructions. So:

The actual installation of the frame is complete, but the solution to the question of how to make a canopy from a profile pipe will be incomplete if you do not pay due attention to the description of the polycarbonate fastening. The differences between a wooden frame and a metal one are in the method of fixing plastic sheets to it. It consists of the following:

1. Since the frame needs protection from corrosion, the carbonate sheet must be sealed on both sides - inside and outside. To do this, washers and sealing pads are used. You can make them yourself from rubber.
2. To speed up installation, rubber rings can simply be glued to the holes in the sheets from the inside. Then, when fixing the screws, they will be pressed against the profiled pipe, and the tightness will be ensured.
3. It is also imperative to use connecting profiles - if you fasten the sheets overlapping and then glue them with a special waterproofing tape, then over time it will become unusable and begin to peel off. Accordingly, moisture will end up inside the canopy or cellular polycarbonate - both are bad.

When the metal frame is ready, it is coated with a special paint that protects the metal from corrosion. Decorative special linings are placed on the ends of the polycarbonate to block the access of moisture. Actually, the canopy made from a profile pipe is ready with your own hands.

Decorating a metal frame

The aesthetic component of any design is important. Therefore, when the welding work is completed, you should clean the seams, process uneven edges when cutting polycarbonate and paint the frame in the chosen color. Plastic can also be decorated - painted, covered with colored film on the inside, etc.

Numerous examples from the network are given to help the owner. Ready-made sheets interspersed with drawings or mosaics that imitate stained glass look dignified and elegant. Decorative polycarbonate is more expensive, but its effect is amazing.

A metal frame for a house adjoining structure requires increased attention both when calculating the entire system and directly during installation. Important questions - choosing a base for the frame, which profile pipe to use for the canopy, how to fix the elements - must be worked out at the design stage.

Currently, a canopy made from a profile pipe can be found in most garden plots. The design is used to protect cars, swimming pools, from wind and precipitation. A lean-to canopy can be a nice addition to your home's porch.

Preparatory stage

Before you start building a canopy, you must:

• develop a design drawing;
• purchase materials;
• prepare tools for work.

Canopy drawings

A canopy made from a profile pipe with your own hands can be of the following types:

• single-pitched, if on the other side the structure is adjacent to the building or;

• gable, that is, a free-standing structure shaped like a house;

• arched.

The type and shape of the future building depends on the amount of free space on the dacha plot and the desires of the users.

A lean-to canopy takes up the smallest area. Its manufacture and installation is faster than other types of structures.

After choosing the design of the canopy, you can begin to develop a drawing.

Any canopy consists of a number of elements:

• prepared site. It could be just the ground, a concrete base or a tiled area;
• when preparing the site, it is necessary to provide support plates, which are the main holders of the structure;
• columns or pillars of a structure;
• roofing and connecting trusses are additional elements that give the canopy stability and strength;
• roof sheathing. Additional lathing is used in the manufacture of a canopy covering a large area of ​​the site;
• roof. For the roof, you can use polycarbonate of various colors and corrugated sheets.

The drawing of a canopy made from a profile pipe should show:

• dimensions of the structure, selected depending on the free area and the wishes of the user. The amount of materials required depends on the size of the building;
• materials used.

Based on the design drawing, a canopy made from a profile pipe is calculated, namely the amount of materials required for manufacturing.

Materials for making the structure

So, the structure of a canopy made of a profile pipe consists of:

• profile pipes of various sizes;
• roofing material.

The selection of a suitable section should be based on the expected load of the future canopy on the load-bearing elements. It is worth noting that it is better to select a profile with a safety margin of 2-3 times the values ​​​​presented in the table.

The load-bearing elements of the canopy must be made of pipes with a minimum cross-section of 80*80 mm. This will give the structure the necessary strength and stability. Additional elements can be made from pipes of smaller cross-section. Pipes 40*20 mm are optimal.

• calculate the surface area that needs to be covered;
• increase the indicator by 5% (minimum stock).

To secure the covering you will need roofing bolts with spacers.

The canopy can be assembled using one of three methods:

• by welding (it is necessary to prepare electrodes for working with a welding machine);

• using threaded connections (purchase the required number of mounting bolts and metal corners);

• using special clamps (various types of clamps are prepared).

It is advisable to protect the frame of the building from corrosion using paint.

Tools required for work

To build a canopy you will need a set of the following tools:

• measuring tape;
• building level to check the verticality of the structure;
• shovel for earthworks;
• grinder for cutting pipes;
• screwdriver;
• drill;
• welding machine.

For safety reasons, it is better to carry out all work wearing protective gloves.

Construction of a canopy

The stages of canopy construction are as follows:

1. foundation preparation. In places where support pillars are expected to be located, soil is removed. A layer of crushed stone is placed at the bottom of each pit. A mortgage is installed, to which bolts are welded for attaching the racks. To give the structure additional strength, you can use reinforcement. The remaining space is filled with cement mortar;

1. All materials are cut according to the design drawing. Trusses are being made. A truss made from a profile pipe for a canopy can be of several types. The shape of the truss is selected based on the type of canopy;

1. The side walls of the structure are assembled. The connecting trusses and support pillars are attached to each other in the chosen way;
2. the finished sections are connected to roof trusses. If a lean-to canopy is assembled from profile pipes, then before installing the roof trusses, the side sections are installed on the foundation;
3. Using a level and tape measure, the correctness of the assembled structure is checked. If necessary, appropriate changes are made;

It is recommended to ensure the verticality and compliance of the structure with the drawing at all stages of canopy assembly.

1. the canopy structure made of pipes is installed on the prepared site and securely fastened;
2. additional roof sheathing is attached;
3. all metal surfaces are treated with protective agents: paint, a special compound, and so on;
4. material for roof cladding is being prepared. The sheets are cut with a small margin to eliminate the possibility of errors in size;
5. the roofing material is secured with special bolts, following the rules;

1. excess parts of the roofing material are carefully trimmed;
2. The surrounding area is being improved.

The entire process of assembling and covering the garden shed can be seen in the video.

You can purchase a ready-made structure and assemble the building on the site or make all the parts of the canopy yourself. If the structure is made on your own, then the ability to use a welding machine is required. A homemade canopy will cost much less than a purchased structure.

A canopy made of pipes and polycarbonate is becoming an increasingly popular architectural form on a personal plot. No wonder, because this building can perform many functions, ranging from an open garage for a car, a wood warehouse, an indoor playground and ending with a recreation area with a barbecue and soft chairs.

The key advantage is the ability to make such a design with your own hands. This article will provide recommendations on the choice of material, examples of calculations of supports and trusses, and how to weld a canopy from a profile pipe.

Calculation of the optimal canopy shape

The length of the rafter depends on the angle of inclination of the truss. For different angles, it is optimal to use different roofing materials:

• 22-30 is the optimal angle of inclination for buildings in areas with significant snow loads. The design of a canopy made from a profile pipe with such an angle provides a predominantly triangular shape. It is optimal for straight and corrugated asbestos sheets, various types of metal profiles and ethernite roofing.
• 15-22 - are also gable with metal types of roofing. This angle of inclination is typical for regions with increased wind loads. The maximum span of a triangular truss with this angle is 20 m.
• 6-15 – predominantly single-pitched trapezoidal trusses covered with polycarbonate and corrugated sheets.

Calculation of a canopy made of polycarbonate from a profile pipe is carried out in accordance with SNiP P-23-81 “Steel Structures” and SNiP 2.01.07-85 “Loads and Impacts”.

The technological requirements for the farm and the calculation sequence are as follows. In accordance with the technical specifications, the required span is determined. Using the presented diagram, we substitute the dimensions of the span and determine the height of the structure. The angle of inclination of the truss and the optimal shape of the canopy roof are set. The contours of the upper and lower chords of the truss, the general outlines and type of roofing are determined accordingly.

Profile selection

As a material for assembling a truss, you can use channels, tees, angles and other profiled products made from steel grade St3SP or 09G2S (in accordance with GOST). However, all these materials have a significant drawback compared to profiled pipes - they are much heavier and thicker with comparable strength characteristics.

The dimensions of the frame elements for a canopy made from a profile pipe depend on the dimensions of the building. In accordance with GOST 23119-78 and GOST 23118-99, the following materials are used to create a canopy from a square pipe with your own hands:

• For compact buildings with a span of up to 4.5 m – 40x20x2 mm;
• Medium-sized structures with a span of up to 5.5 m are made of corrugated pipe 40x40x2mm;
• Structures of significant size with spans of more than 5.5 m are assembled from profile pipes of various sections 40x40x3 mm or 60x30x2mm.
• The size of the canopy stand made from corrugated pipe is 80 80 by 3 mm.

Drawings, dimensions and main connections

Before you begin assembling a canopy from a profile pipe with your own hands, you need to draw a detailed plan of the entire structure indicating the exact dimensions of all elements. This will help calculate the exact amount of materials of each type and calculate the cost of construction.

In addition, it is advisable to make an additional drawing of the most complex structures. In this case, it is a single-pitched truss and the fastening points of its main elements.

Scheme for making a truss from a profile pipe for a canopy with the main fastening units

One of the main advantages of a profile pipe is the possibility of a faceless connection. This is manifested in the simplicity of the design and low cost of the truss with a length of rafter spans of up to 30 m. In this case, the roofing material can rest directly on the upper chord of the truss, provided it is sufficiently rigid.

The advantages of a bevelless welded connection are:

• Significant reduction in truss weight, compared to riveted or bolted structures, up to 20% and 25%, respectively.
• Reducing labor costs and manufacturing costs, both for single products and for small-scale production.
• Low cost of welding and the ability to automate the process by using devices with a device for continuous feeding of welded wire.
• Equal strength of the weld and the products being connected.

Disadvantages include:

• The need to have quite expensive equipment;
• Welding experience required.

Bolted connections in the production of products from profile pipes are quite common. They are usually used in collapsible awnings made of profile pipes or in products produced for mass consumption.

The main advantages of such connections are:

• Easy to assemble;
• No additional equipment required;
• Possibility of complete dismantling of the structure.

Flaws:

• The weight of the structure increases;
• Additional fasteners required;
• The strength and reliability of bolted connections is somewhat lower than welded ones.

Summing up

The article examined the design and methods of making the simplest single-pitch canopy from a profile pipe with your own hands, however, profiled pipe is a rather “flexible” material from which complex and aesthetically attractive structures can be made.

Owners of private houses and summer cottages often need to install a canopy, open garage, gazebo or shed on their property. Not everyone knows that you can make a durable canopy quickly and with a minimum of investment. In addition to protection from sunlight, wind, rain and snow, a canopy is also an excellent design solution for decorating a site.

Does your car still freeze in the freezing cold, rust and become covered with a crust of ice when frost sets in? Then we go to you! Now we will look at how to make a metal canopy for your car and protect it from exposure to precipitation, ultraviolet radiation, branches and anything that might fall from the sky.

Is it expensive? The materials will only cost a couple of thousand rubles, but as a result you get a neat canopy on a metal frame that will last for decades and, if necessary, can be easily dismantled and moved around the yard. We bring to your attention step-by-step instructions, using which you can build a canopy yourself quickly and quite successfully, even if you do not have special construction skills.

Preparatory work for installing a lean-to metal canopy

We could also consider gable structures, but the purpose of this particular article is to make an extremely practical, simple and cheap canopy with a metal frame, so we chose a lean-to structure. Make it 2 times faster, since there is no need for bent trusses, joining the roofing material in the center and 30% less materials will be needed. Let's look at all the instructions step by step and start with the preparatory work.

STEP 1 : choosing a place for a lean-to canopy. You can build wherever there is space, but it is better to choose a small hill in the yard and a place with shallow clay so that water after rain does not accumulate under the canopy, and you can spend a minimum of money on installing concrete under the supports. Feng Shui lovers are not welcome here, since the main thing here is practicality.

STEP 2: selection of materials. We have already chosen it. Our supports will be made of a metal square 40x40 mm, we selected it taking into account the load of the structure and the possible wind load of 4%, and we also did not forget about precipitation for the harsh climate zone. The supports are designed for a metal canopy with a slope of 15-20% and dimensions of 4x4 meters. The roof can be made of polycarbonate, but we still preferred metal sheeting because it is inexpensive and easy to work with.

STEP 3: clearing the area . We will use a concrete floor for the car, so the area needs to be planned and about 10 cm of earth removed to be filled with slag and a screed of at least 5 cm thick to be installed. This is a lot, quite enough for a heavy SUV (within reason, up to 2500 kg). If you want to buy a hummer or tractor in the future, then your screed depth will be at least 12 centimeters.

STEP 4: we calculate communications . Yes, you heard it right, there will be more communications around the canopy. For what? It's simple. Firstly, water will not wash it away and will not flow under the canopy, and secondly, it just looks cool and is inexpensive. These will be low tides in the ground and drainage systems. In addition, it is necessary to supply electricity to the canopy just in case of a fire (suddenly there is no place to barbecue or you need to warm up the car) and make future wire leads from under the screed or along the supports.

Metal carports can be of different sizes, you can make it just for a car, or you can create a parking lot for 3-4 spaces (what if your mother-in-law comes to visit or former classmates), it is better to think about this in advance, since expansion will be problematic. At the very least, you need to pour the foundation and supports immediately for the size of the canopy you have chosen and start manufacturing after the calculations. Look like that's it. Now we have prepared the site, gathered ourselves mentally and took courage - we can go build.

We install metal poles for the canopy and sheathing

Making the frame is the hardest part, since installing the roof and decorating it is already a piece of cake and even a child can do it. But the frame must be made carefully, do not be lazy, use a level and often check the correctness of the work. If you install the supports or screed unevenly, then it will be possible to correct it, of course, but it will take a lot of time and effort, because it will almost completely redo everything. Let's look at how to make a metal canopy with your own hands according to GOST in detailed instructions.

STEP 1: install supports . There are about dozens of different methods for installing supports, but we won’t bother with the bottom straps, we’ll just make a 40-50 centimeter hole in the ground with a drill or shovel, place a metal profile in the center and fill it with concrete - the support is ready. Here it is important to install the supports vertically, measure everything with a level so that they are in the same plane. We make a 1:3 concrete solution.

STEP 2: top harness. But you need to tie the supports at the top, since their height will be 270 centimeters above the ground and 240 cm, respectively, on the other side, where there will be a slope (we chose exactly this height), they may deviate slightly. Therefore, at the top along the perimeter it is necessary to weld a metal profiled pipe, the length of which will be equal to the length of one side (we took the dimensions of the canopy 4x4 meters as a template).

STEP 3: sheathing. Since metal sheds with a pitched roof do not require bent elements or joints in the middle, making sheathing is as easy as shelling pears. It is necessary to weld a metal pipe every 60 centimeters between the sides of the canopy with a height of 270 and 240 cm to form a slope. We will get about a 20% slope, even a little less - this is quite enough for the metal frame of the canopy to successfully cope with any amount of precipitation.

Now all that remains is to screw the roofing material. The frame will cost only 3,500 rubles, you can still save by installing jumpers every 80 centimeters, instead of 60 cm as we did, but it’s better to have a margin of safety, you can lighten the structure only if the carport is located in a cozy place in the yard and not exposed to strong winds.

Selecting and attaching the roof to a metal carport

As we said earlier, you can lighten the structure and attach polycarbonate to the roof, but this will not be very rational from an economical point of view. It is best to make a single-pitched metal canopy from corrugated sheets. In addition, there is no need to bend it, straighten it, put tricky washers in it, and it’s not scary to tighten it a little. Installing it is easier than a steamed turnip, let's look at the step-by-step instructions:

STEP 1: drill holes . You need to lift the metal sheet and make holes in it at the level of the metal beam that connects the sides of the canopy. This can be done simply: place the sheet on the beam, mark from below with a marker where the holes need to be made, remove and drill them. Holes every 35 centimeters.

STEP 2: drilling out a metal carport . Holes can be made either in advance in the marked places, or when the sheet is already applied to the frame and a jumper can be drilled through the hole on the corrugated sheet. It is necessary to use special screws with sealing caps so that the screwing points do not rust. You can use plastic washers for work, it is convenient and cheap.

STEP 3: processing with protective materials. It is better to use deep metal impregnations and varnishes so that our work lasts for many years. When using varnish, metal awnings for summer cottages last at least 2 times longer, since even the high acidity of precipitation does not cause corrosive processes.

We looked at how to make a metal canopy without the help of a specialized team, but we also suggest watching a video on how to properly screw corrugated sheeting to a metal frame to avoid mistakes:
