Home-made sliding gates can be used not only in residential, but also in industrial buildings. Such designs are very popular because of practicality, because the sash is placed along the fence and almost does not take up space. Such systems are not cheaper than oar, as for the work you will need special accessories.
The swing structure must be fixed in windy weather, because there is a possibility of getting hit by a blade or damaging the machine. Gusts of wind will make great efforts to open or close such a gate. This usually takes a lot of time. First you need to open one leaf and strengthen it, and then do the same with the second. After you manage to leave the yard, you will need to do everything in the reverse order.
At sliding gates the principle of operation is different. It will be necessary to move the sash or close it without fixing. And if you complement the design with automation, you can do this without leaving your car.
Preparation of tools and materials
If you decide to make home-made sliding gates, then you need to take care of the availability of:
- welding machine;
- an ax;
- roulettes;
- a hammer;
- shovels;
- grinders;
- building level;
- screwdriver.
In the next step, you can calculate the cost and quantity of materials. If we are talking about gates of standard sizes, then everything you need can be purchased at a hardware store or at a metal depot. In this case, the opening should have a size equal to 4 m.
To fix the mortgage you will need a concrete mortar. Do not forget to purchase roller carriages and corrugated board. The solution is mixed from a part of cement, three parts of crushed stone and the same amount of sand. Roller carriages are mounted on the mortgage. To increase the strength on the channel, it is necessary to weld fittings, the length of which does not exceed 1 m. You will need individual meter sections in the amount of 7 or 8 pieces.
The door leaf will have a size equal to 2x4 m. On one side, the structure is sheathed with corrugated board. To do this, you need about 200 screws. Decking is acquired taking into account the area of 10 m 2 . Buy a pack of electrodes, a primer jar, solvent and paint. You should take care of the presence of a square pipe with a side of 6 cm. Its length should be 5 m. If you want to make a gate according to your own dimensions, then you will have to carry out the calculations yourself.
Work on the basis for the mortgage
Before you make homemade sliding gates, you will need to create a foundation. The length of the mortgage should be equal to half the width of the gate, that is, 2 m. Meter segments of reinforcement should be strengthened to this element. Their diameter should be equal to 1-1.4 cm.
A hole is dug in the ground, it is necessary to deepen by 1 m. The width of the trench will be 30 cm. If you decide to make home-made sliding gates, then at the next stage you need to knead the solution, for which 100 kg of cement, 300 kg of sand and the same amount of fine crushed stone.
Ready concrete is poured in such a way that its surface reaches one level with a mortgage, otherwise water will flow into the recess. While the base dries, you can pick up accessories.
Fixing pipe installation
Catchers and top rollers must be secured with a profile pipe. Its cross section will be 3x6 cm. It is positioned along the height of the column and in those places where the fittings will be installed. It’s better not to make homemade rollers for sliding gates with your own hands , but if you still want to do this, you can use a thick-walled pipe.
The fastener can be fixed in one of two ways. The first is the use of concrete, in which the channel is recessed. An alternative solution is the removal of several bars of reinforcement from the column. Then a profile pipe is welded to them. Fasteners are reinforced with anchors. Over time, anchors can become loose.
Concreting is a more reliable, but labor-intensive way. The fastening will look like this: the lower rollers are installed at the first stage, and after that you can proceed with the installation of the door leaf. Top mounted top rollers. The lower catcher must be welded with the orientation on the line along which the canvas approaches the post at the opposite end.
Making homemade sliding gates with your own hands, the mortgages will need to be welded to the pipe using corner profiles. Mortgages at the next stage need to be painted in the color of the door leaf. If you do not collect mortgages, then it is worth bringing the reinforcing bars as accurately as possible to the catcher, which is quite difficult. Anchors may be mounted, but this will not ensure reliability.
Hardware selection
After you have completed the mortgage, you can proceed to the selection of components. This should include a 5-meter guide rail. Need roller carriages and plugs. You should purchase rollers and grabs. For the independent manufacture of components, you will need special equipment and knowledge in the field of technology. As a result, home-made accessories are more expensive than factory ones.
You must first determine the length of the rails. This value is 1.5 of the opening width. The value can be reduced to 1.3 widths, but it can be taken only in two cases: if there is not enough space for opening, or the weight of the gate is less than 250 kg.
The fittings are usually designed for a specific weight, which does not exceed 800 kg. If the canvas is planned to be sheathed with corrugated board, then accessories should be selected for a weight within 400 kg. However, if the material weighs a lot, it is better to opt for 800 kg. The canvas will move on plastic and metal rollers. If you operate the design correctly, then both options will be ready to last a long time, but it is better to prefer plastic rollers, as they make less noise.
When buying, you need to pay attention to the upper grip and rubber plugs. If all the components are made carefully, then the manufacturer uses high-quality equipment. You should not opt for parts sold in plastic bags and with uneven edges. This is a sign of handicraft production.
Carcass construction
When making homemade sliding gates on bearings, you must prepare a place for their assembly. Pipes with the following dimensions should be selected for the frame: 5x5x0.2 cm. Products are cleaned of rust and scale and then coated with a primer. After the pipe dries, the frame is assembled together. The joints should not have openings where water could penetrate.
The next step will be the manufacture of an internal frame for fixing corrugated board. The smaller pipe is placed on the larger. The dimensions of the first will be 4x2x0.2 cm. The pipes are welded in a checkerboard pattern, the distance between them should be 40 cm. This will exclude a change in the linear dimensions of the frame when exposed to temperature. Welding places are treated with a grinder and coated with a primer.
Gate mounting
Roller carriages are installed on the mortgage, and gates are placed on them. Using the construction level, the position of the structure is checked vertically and horizontally. If everything is done correctly, then the carriages can be welded to the channel. For this fastening, some use bolts, for this there are corresponding holes in the cells.
Welding is more suitable, because if necessary, you can cut and move the carriage. This mounting method is no less reliable. Mortgages for other components are prepared from the pipe. The end of the guide is complemented by a roller with clamps, after which it is closed with rubber plugs.
Automation manufacturing
In order to make home-made automation for sliding gates, you will need to fix a bicycle or motorcycle sprocket on the gear shaft. A chain is put on it, the diameter of the links of which will correspond to the type of asterisk. Fastening should be carried out to the rotary canvas in a horizontal position.
When the sprocket rotates, chain rotation is transmitted, which helps to open the gate. The engine must be fixed to the gear mechanism. It is located on the frame. To do this, you can use angle steel. A frame is mounted on a concrete base. The duration of operation of the mechanism will depend on the rigidity of fixation.
Work on the gearbox
Making home-made automation for sliding gates with your own hands, you will need to choose a gearbox with a motor. In this case, it is necessary to navigate along the height of the axial rotation. If there are different values between these two mechanisms, then a two-level base will need to be built. For fastening the motor and gearbox, it is necessary to use bolts with nuts. The support for them should be rigid and even. The chain is mounted on the gate. It is attached to rail guides. An additional drive beam is fixed on the canvas. The chain is 80 cm away from the ground.
Finally
Homemade gearbox for sliding gates can be made using blocks and cables, as well as a suspended load. At the same time, the gates will constantly strive to roll back to the open position. A pulley is made from a piece of pipe with a welded washer, which complements the engine.
The mechanism will wind the cable and pull the gate to the closed position. Such a home-made mechanism for sliding gates will work until the trailer is activated. Such a scheme is very reliable, but it is important to adjust the engine so that the cable does not break under the weight of the load.
