Metal gates of the simplest design, which are often mounted on country cottages, are two symmetrical flaps forming a swinging structure. Metal gates are manufactured using the following parameters: width - 3 meters, height - 2 meters, these dimensions can be adjusted, based on the needs of the owner of the site or tasks that the gate should perform. In the event that the width of the gate is too large, the design will experience excessive loads, so the dimensions must be calculated carefully.
One of the most common materials from which the door leaf is made is corrugated board, the doors can be latticed or forged, in principle, various inexpensive materials are used in the manufacture of such structures.
Types of gate constructions.
The most common scheme is when two gate leaves are hinged. There are also complicated designs, when the flaps and gates can be more than two, besides the protective function, the gates perform decorative functions, the high-quality and well-executed gates will give the suburban area a well-groomed and accurate appearance.
Iron gates made from corrugated board.
As poles for gates made from corrugated board, a profile pipe with a wall thickness of not less than 2 mm and sizes 60-60 is used. Calculation of the amount of necessary material is as follows: the total length of the fence is divided by the distance between the poles, one column per each wicket is added to the received indicators, and one more for each gate and one pillar for turning. Between the poles it is recommended to leave a distance equal to 2.5 meters, this length will provide the necessary rigidity, and will avoid the rupture of the structure during the change of seasons.
In the role of the log fence, a metal profile pipe can be used, with a wall thickness of at least 2.5 mm, a size of 40 × 20.Calculation of the amount of material occurs according to the following scheme: the number of logs that need to be installed in each span, they must be at least two, multiplied by the length of the future fence, and the length of wickets and gates added to the result obtained.
For the production of sheets for fence, you need to choose a profile, the thickness of which should be at least 0.5 mm, the height of the profile rib should be 2 cm. The required amount of material is calculated based on the working width of the sheet, for example, for the C20 sheet it is 1100 mm. The total length of the fence should be divided by the working width, the result is equal to the required amount of corrugated board, in addition, at least one sheet in the stock is needed.
It is recommended to fasten the sheets to the frame with screws, it is recommended to choose a quality fastener, otherwise the drilling of the log will take an unreasonably long time.
In addition, in the manufacture of swing gates, the following building materials and tools will be needed: awnings( hinges) - 4 pcs., Sheet corrugated board, drill( screwdriver), screws, cement, stone or broken brick, shovel, sand, Bulgarian, welding machine, paintand brushes, metal pipes.
Tool required for mounting the structure.
For the installation of both the gate and the fence, a certain tool is required, depending on the type of construction and material used: welding machine, level, sledgehammer, tape measure, shoelaces, drill or benzorb, bulgarian.
Manufacturing of supports and frames for metal gates.
The production and installation of a metal gate will not cause any particular difficulties. First of all, supports are made, as a material, pipes made of steel with a diameter of 10 cm and a metal profile, I-beam or channel, with a shelf width of at least 100 mm are used. Depending on the degree of strength and rigidity of the support it will be possible to judge the durability and reliability of the construction of the gate. It is best to make the sash from a profile of metal of rectangular or square cross-section. The optimal option is the condition that the width of the profile shelf is not less than 40 mm.
Installation of metal gate supports.
The installation of supports for the gate must be carried out more thoroughly than for the fence, the reason for this is the increased load tested by the axles when closing and opening the doors. Therefore, it is necessary to install the gate supports very thoroughly. As awnings for metal swing gates, garage hinges are constructively optimally suitable, it is better that the diameter of the inner section is more than 120 mm. For gates of simple design, four pieces of hinges will suffice, for a more massive project, six canopies are needed. To each loop thoroughly on both sides in the area of the entire contact contour, metal plates 0.5 cm thick are welded.
Mounting of the gates of the gate.
gates. For the production of girders for gate gates, it is necessary to take a square profile, from which it is necessary to cut two identical pieces, which must be 15-30 cm shorter than the height of the gates. The stakes are welded to the plate loops, both designs should be the same. After that it is necessary to fix the structures on the gate supports with fasteners, which must be clearly checked horizontally, and vertically. The work should be done in such a way as to make as little gap as possible between the support post and the stand, preferably up to 3-5 mm. After fixing the stand, you need to cut the top piece of the profile to the size, after which it must be installed on the upper ends of the racks. The structure is inspected on a level position of all components, after which the entire structure must be "dotted" by welding.
The final stage of installation of the Iron Gate.
After preparing the frame, the two central pillars are installed in the center of the gate, so that the gap is about 10 mm between them. All the central racks also "finish" welding, and the plates are welded thoroughly to the supporting posts. To strengthen the construction of the gate, it is necessary to take a steel sheet 4-3 mm thick, from which 8 blanks are made, which must be attached to the corners of the leaflets. At the final stage, the frame structure is divided into two halves by a bolgar. The optimal option is to perform the minimum gaps in the hinges, in this case, the displacement of the valves can be practically avoided. As a decorative design solution, it is possible to finish the outside of the gate with some material.
