The gate is an integral part of the protective construction of the suburban area. Today, there are many varieties. Let's consider the process of manufacturing and installation of sliding gates with their own hands.
Advantages and disadvantages of
The door structure is divided into several types, each of which is different from each other:
Regardless of the type of construction, sliding gates require free space along the fence on one side. At the same time it should be equal in size to the opening. As for the console systems, the place should be more by 120-200%.
Features of self-calculation
Design calculation one of the most important and priority stages. Ignore this stage is not worth it, since the construction of recoiling is much more difficult than swing.
The calculation process includes the following steps:
The calculation of the width and height of the structure should be repelled from the market mix. So, if a profile or a pipe can be easily welded, then cutting the sheets of corrugated board is very difficult to add. Plus, the result will be unaesthetic.
Sliding gate calculations
Moreover, understanding how much weight the structure will be in the final account, selected mechanisms and moving parts that can cope with the load.
If the canvas is supposed to be large, then be sure to consider the wind load. To the existing wind force prevailing in your area, add a small margin.
Although the easiest way to get a calculation is to contact a specialized company that provides a folder with drawings and calculations, you can do it yourself. It is worth noting immediately that all the above calculations relate to cantilever-type sliding gates. They are harder on all other types, so consider them in more detail.
The width of the door (L) will be:
On the basis of this L there will be more openings.
When moving, the valves should be balanced. This indicator is achieved by calculating the counterweight. Due to this, the specific gravity of the structure will be evenly distributed throughout the carriages. Accordingly, in order to make the load as small as possible, the counterweight must be large.
But what if there is not enough space for the movement of the sash? In this case, you must understand that the length of the counterweight should not be less than 40% of the width of the sash. The ideal rate is 50%. As a consequence, the width L in its design has a counterweight.
With such calculations, you can determine how much space is needed to roll the gate along the fence.
This value is determined based on the weight of the material used:
Gates with a 4 * 2 m frame will have an average weight of 200 kg. Having such data, you can determine the performance of the guide beam. In this case, you can build on the standard.
For a gate weighing 300 kg, a beam of 9 * 5 cm and a thickness of at least 3.5 mm is sufficient. However, a safety margin of up to 40% is required. It will greatly simplify the operation of the gate and increase its operational life.
The gates will need rollers, catchers and support tire. Modern products of such a plan allow you to choose the necessary design. We take the simplest wind load estimate, which is 12 m / s up to 90 kg / m 2 and is evenly distributed over the supporting zones of the canvas.
How to make sure that the structure made by you will work without interruption even in strong winds? For this, it is necessary to achieve that the strength of the fittings is greater than the calculated gate weight. It also takes into account the lateral moment of 100 kg / m, multiplied by 8 kg / m, which equals 800 kg / m. In principle, this is a little ~ for each supporting element 150-180 kg / m.
When buying a roller mechanism, make sure that it has a margin of up to 30% in relation to the weight of the gate. But this figure does not affect the life. This is directly affected by increasing the distance between the centers of the carriages.
In addition to all the above, attention should be paid to other aspects. Pay attention to the rail for the gate, supports for roller carriages and the number of anchors. It is also important to correctly calculate the mortgages on the support pillars. In this case, it is necessary to build on 60% of the total mass of the gate divided by the number of mortgages.
As for the calculation of the foundation, there are no special secrets here. But despite this, you should not lose sight of this component, because often the cost of the foundation reaches 40% of the total project cost.
This type of gate has the following structural elements:
Roller bearings are installed on the foundation, which take up the load of the guide beam. The rollers are placed inside the carrying console.
Sliding gate door
High doors are also presented to the gate leaf requirements. Its structure must be sufficiently rigid and stable. It is important that in case of a strong gust of wind or ice, the flap functions well. Moreover, it is necessary to equip it with additional stiffening ribs so that it does not sag under its own weight. All this should be considered when creating drawings.
The presence of various components directly depends on the height and width of the leaf, as well as its weight. So, today on the market you can find a number of companies that provide quality equipment, namely:
For example, we will make some calculations. In the basic configuration, a carrier rail must be installed, 6 meters long. And in order to choose the right components for it, you must take into account the length of the sash and 40% plus. Also selection is carried out along the length of the guide beam and possible loads. So, if the opening width is 3.8 m, then the length of the gate is 3.8 m + 40% = 5.32 m.In this case, you can purchase a ready-made set with a beam of 6 m.
If the opening width significantly exceeds 4 m, then the purchase of components should be oriented taking into account the load of 500 kg. In them, the guide beam has a wall thickness of 3.5 m, and a section of 71 * 65 mm. If the width is more than 6 m, then it is necessary to take from the calculation the load up to 600 kg.
Installation of sliding gates
The web movement should carried out from the inside of the plot, namely along the fence. Based on this, it is necessary to prepare a place for the gate, so that absolutely nothing would interfere with this process.
The installation process includes 4 steps:
Stages for the construction of the foundation:
The embedded element must be flush with the road surface. The minimum clearance that is allowed between the lower edge of the gate and the road is 10 cm. This gap can be increased by means of an adjustment platform. But to reduce this gap will be impossible without breaking the bindings.
Mounting the mortgage
If for one reason or another a gap of 100 mm does not fit , then make a deep installation of the embedded element.
As for the concrete work, they are carried out when the installation of the mortgage element is fully completed. The level of concrete must be flush with the mortgage element.
Installation of the gate
When the foundation is frozen, you can start installing the gate. To do this, first of all you need to make markup. On the line of the opening, not reaching the counter post of 30 mm, pull the cord. This cord is the trajectory of the gate movement. Cord tensioning height - 200 mm. Further work is as follows:
After it is necessary to weld the second carriage of the adjustment platform. Then roll out the door leaf in the opening and make the final adjustment of the position. Make a small tack welding of the second adjustment platform, as a result of the action look like this:
The drive of the sliding gate
Perform holes in the supporting profile, this is necessary in order to install the cart correctly. To do this, loosen the upper nuts attaching the carts to the platforms. After that, roll the gate back / forth. If the sash is free, tighten the nuts. If there are some difficulties in moving the sash, the fasteners slightly loosen and level up all the design flaws, for example, correct the carriage distortions.
Installing the rollers
At the next stage of work, the door frame is trimmed. For this you can use profiled sheets of metal. They must be cut to size of the sash. Fastening is carried out by rivets or screws. Each subsequent sheet is mounted overlap.
When the casing can be completed, you can install the bottom / top trap. The lower catcher performs the role of reducing the load on roller trolleys in the closed state. Therefore, they must be installed with a loaded gate. Place the lower catcher under the end roller with the gate completely closed so that the catcher's reference plane is higher than the level of the end roller. As for the installation of the upper trap, this process takes place in the same way.
At the end, it remains to install the automation. To do this, fix the rack rail, which implies a universal part with electric drive. Usually it is included in the fastener kit.
The choice of automatics directly depends on the weight of the gate:
All metal elements of the gate are necessary to paint. Pre-degrease the surface. To do this, clean the surface and grind with a grinding wheel on the grinder. Some places, for example, protected, wipe with acetone. Now you can proceed to the primer. It is applied evenly. Moreover, the primer should be applied in such a way that there are no drops and streaks. Thanks to such preparatory work the paint will fall evenly. As a result, the entire structure of the door will be completely protected from the appearance of corrosion.
Paint should be applied in two layers and only after the first one has completely dried.
For all the work, you will need to have such a tool:
If you do not have enough experience in performing such work, then there is a big risk of making certain errors:
