Features of sliding gates on screw piles

Entry to any territory, be it a private house or storage space, always takes place through the gate. They can be in different versions - hinged, sliding or sliding. Now becoming increasingly popular recoiling. Such demand is easily explained by the ease of installation and operation of the gate. These designs save the working space in the area and require less special skills for installation. Retractable gates can be mounted in different ways. They are mounted on rails or screw piles.

Any construction begins with the foundation. Installing sliding gates is no exception. But the soil is not always homogeneous on the construction site.If the gates are long, for example, from 6 m, then areas with marshy soil can be encountered. During operation, the foundation may fail in some places. This will lead to a distortion and failure of the gate.

To prevent basement shear, the method of installation on piles is used.

It has a number of significant advantages over rail recoiling structures:

• During operation, the rails do not need to be cleared of accumulated dirt and other debris.
• The installation of the gate on the piles reliably fixes the structure - the gate does not warp even on swampy and clayey soil.
• Sliding gates on screw piles are mounted without an upper rail, and this will allow trucks with high sides or refrigerators to enter the territory.

In addition, if the gates are installed on the territory where the buildings are already standing, it is not always possible to install sliding structures on rail guides. Screw piles do not create such a problem.

When choosing a place to install sliding gates on piles, you should take into account the installation features. If there is a rocky surface under the soil layer, then it will be necessary to use much more time and equipment to install the piles.

Such gates should be installed on the ground, which will allow to go deep by 2-3 meters. Piles can be compared with large screws that are screwed into the ground. If the soil is mixed with stone, it will be difficult to do. The distance between the screwed piles depends on the length of the blade, but is usually 2.5-3 m.

The installation itself takes place in several stages:

• First, the installation location is determined. It is necessary to take into account not only the condition of the ground, but also the availability of free space for roller mechanisms.
• Calculations are made, on the basis of which produce markup.
• With the help of ordinary garden drills, small recesses are made. Then piles are screwed into them.
• The piles are aligned on the upper level of the ground, the empty space of the piles and the cavities around them are filled with concrete.
• The guide channel is welded, roller mechanisms are mounted.

For the correct choice of the diameter of the pile, the dimensions of the web are taken into account.They must withstand a substantial load from the wind and the weight of the structure itself. Accordingly, the larger the size of the gate, the thicker the piles should be.

After installing the piles and assembling the web, additional elements are installed on the structure. - roller guides and catchers at the top and bottom. Catchers are mounted on the receiving pole and securely fix the gate in the closed position. Pile length and diameter directly depend on soil composition.

Piles are made of anti-corrosion materials with an additional protective coating. Such requirements are imposed on all piles, regardless of what type of soil they will be installed on. When choosing them you need to pay attention to the availability of a certificate of quality.

Piles are standard sizes - from 57 to 89 mm. The blade pitch for them varies from 2,000 to 4,000 mm. Depending on the size, they can be installed manually or with special equipment. For the manufacture of the door frame used profile pipes. They differ in diameter and can range from 50x50 to 60x40 mm. Structural stiffeners are also made from the same pipes, but with a smaller section.

For facing of a gate the professional flooring (the pro-thinned-out sheets) is used.It can be both one-sided and two-sided, have a different shape and depth of the wave. These parameters carry only the design load and do not affect the quality of the gate. Profiled flooring can be sheathed gates from both one and two sides.

Additionally, the design is equipped with fittings necessary for their operation:

• Rail of anti-corrosion material for the direction of movement.
• Console beams of different weight.
• Carriages (roller bearings).
• Upper and lower sash catchers.
• Plugs and knurled roller.

Retractable gates are necessarily equipped with an automatic opening system. It is an electric motor with a toothed rack. When installing an electric motor with it, additional accessories are usually mounted - a battery to ensure uninterrupted operation, photocells and signal lamps, and manual control panels.

Electric motors are installed on the door structure. They open the canvas only in one direction, so these shutters can be installed on the corner sections of the fence. When installing a frame, on both sides of which there will be a fence, you need to take into account additional space in the project.For normal opening at such installation sites, it is necessary to allocate an additional 1.5 m wide from the inside of the fence. This is caused by the design features of the gate - except for the leaf itself, they have a cantilever part, which remains on the very foundation with supports and a drive.

In addition, the installation of the channel in the bottom of the pile can be made not rigid, but adjustable. This will allow to change the height of the lower edge of the gate. Such an attachment option would be an excellent choice if in the future it is planned to lay asphalt or concrete slabs.

The standard price for the installation of sliding gates does not exist. It is individual in each case and is formed from several factors. First, it is the total cost of the materials used in the manufacture of the structure - the frame frame, the dimensions of the canvas itself, accessories and additional equipment.Also this component is influenced by the brands of the materials used and their quality.

Secondly, it is the cost of the preparatory work. Piles are of different lengths and diameters, which directly affects the price of their installation. The cost of installing the gate also affects the rental of special equipment - its delivery to the installation site and the price of work. If the soil is soft and the sizes of the piles are small, then the installation can be carried out manually, without using special equipment.

Installation work on installation includes the cost of services of working teams. The final cost depends on the price of delivery of materials to the construction site. If electricity is not connected to the territory, you will have to pay for the rent of electric generators. Night work will require the use of additional equipment - lighting fixtures (masts or light towers).

General recommendations when choosing types of sliding gates for site owners:

• When choosing a specific type of structure, it is worth conducting a professional study of the soil of your site, to get acquainted with reviews on the types of structures. You also need to take into account the time of the year - only summer days are suitable for pouring the foundation.
• Retractable gates on a monolithic foundation with column supports can be installed in places where the ground is uniform in structure and not subject to shifts or subsidence.
• If the features of the site do not allow to install such a gate, it is worth stopping the choice on sliding options with screw piles.
