We mount a fence from a metal profile
After the acquisition of a country house, a plan was drawn up for its reconstruction, the first point of which was the installation of a new fence. The old fence with a wicket and gate was wooden and lopsided - it was decided to demolish it. In order not to leave the site without fencing, the old fence was left until the end of the works. The new fence was rendered half a meter in front of the old one - there was enough space for this.
Installation of a fence from a metalprofile
When choosing a material for the fence, various options were considered: brick, natural stone and ready-made concrete panels (the so-called eurofence). The first two technologies were abandoned immediately due to their high cost and laboriousness of the installation, and doubts about their durability arose regarding the concrete panels. As a result, the choice fell on a fence of steel profiled sheet mounted on a supporting frame.
To reduce the cost of reconstruction, most of the works that do not require specific skills were planned to be carried out on their own.Due to the lack of a welding machine at that time, the parts of the structure were joined using studs with nuts and washers. This somewhat complicates and delays the process, however, as a result, it allowed saving an amount equal to half the cost of materials.
Design and settlement activities
Before the start of work, the site was measured, a preliminary design was drawn up and the material requirements were calculated. The total length of the metal profile fence was 23.6 meters, the minimum height is 1700 mm. The plans included the installation of an entrance gate with a width of 0.8 - 0.9 m and entrance gates with a width of 3.0 m. The movable elements of the barrier are hinged, opening outwards.
After the calculations, a list of materials required for the construction of the fence was compiled, which includes the following items:
- Steel profiled sheet C-8x1150 dark red color 1,7 m long - 4 pieces and 1,5 m - 16 pieces.
- White silicate brick - 500 pieces.
- Portland brand cement 500 - 5 bags of 50 kg each.
- Sand washed and sifted career - 5 tons.
- Crushed stone of mixed fractions - 5 tons.
- Steel profiled pipe with a section of 40x40 mm - 60 running meters (lm), with a cross section of 20x20x1.2 mm - 24 lm.
- Corner steel 25x25x3.5 mm - 30 lm
- Steel sheet 2 mm thick - 1 piece.
- Channel M12 - 4 pieces of 2.5 m.
- Canopies - 5 pieces.
- Fasteners: 8 mm studs, M8 nuts, washers, self-tapping screws, aluminum rivets and M8 bolts with a large screwdriver head.
The following tools were required for the installation of the fence:
- Spade bayonet and shovels, buckets for bulk materials and water.
- Trough for mixing concrete.
- Angle grinder with cutting and grinding wheels.
- Electric drill with a set of drills for metal.
- Electric screwdriver.
- Tool for installing rivets.
- Locksmith tools: wrenches, pliers, tongs, screwdrivers, and nail pullers.
- Roulette, hydraulic level, plumb, angle, cord and pegs.
- Electric extension 50 m.
Materials were purchased in one company, which reduced the time and get a small bonus in the form of delivery at the expense of the seller. Storage was carried out in the yard under a canopy to avoid wetting in case of precipitation.
Site preparation and marking
The site in front of the old fence was cleared of vegetation and debris. At the extreme points were set pegs interconnected by a cord.With the help of the hydraulic level, zero marks were made, from which the height of the erected fence was measured. At the places of installation of the gate and wicket, additional pegs are installed. The intervals between them were divided in equal parts and also indicated by the installation of pillars.
The next item on the plan of work involved the preparation of a trench for a sand-gravel bed and pits. The depth of the moat should be at least 20 cm, and the depth of the pits under the columns should be about 80 - 90 cm. The excavated soil was evenly distributed over the area in front of the yard and leveled. The dumping of the cushion was carried out in two layers of equal thickness: first, gravel, then sand flush with the earth's surface.
Support poles 2.5 m long each were installed in the two extreme pits so that their height was not less than 1750 mm. After the completion of the pouring of the pits, the vertical position of the pillars was checked with a plumb line. The composition of the sand-cement mortar was introduced gravel to increase strength. Previously, all the columns were coated with a primer to protect against corrosion.
Between the installed columns at a level of 25 cm from the ground, cords were strung, indicating the height of the supports and the brickwork.At this preparatory activities were completed and it became possible to proceed directly to the installation of the fence.
Installation of columns and brickwork
At this stage, an assistant was needed, whose tasks included mixing the solution and feeding materials. The first to install and concreted columns. Work was simplified by the tense cords. They denoted the plane of the fence, and to control the verticality of the installation it was necessary only in one direction. Channels were installed and concreted at the gate installation points.
Between the posts, brickwork was performed at the level indicated by the bottom cord. The basis for it was a sand pad that was poured in and compacted at the previous stage. In the process of masonry, a trowel and a special mason's hammer were used. The gaps for the installation of gates and wickets were left empty.
Installation of the bearing frame of the fence and sheathing profiled
A corner was fixed on top of the support posts with the help of scraps of tubes with a diameter of 10 mm and a length of 15 mm, as well as M8 bolts with nuts.At the level of 50 cm from the brickwork was installed profiled steel pipe. The installation of these elements with studs and nuts was carried out after preliminary drilling.
Profiled sheeting was fastened to the carcass installed at the previous stage with the help of rivets and self-tapping screws. This operation was carried out as follows: the sheet started up at a corner and rose all the way up. In this position, it was fixed with the help of wooden wedges, which were installed between the masonry and corrugated flooring. In the right places holes were drilled and the sheet was riveted to the corner and profile.
Manufacturing and installation of the gate and gate
This operation was carried out in two stages: the wicket and gate frames were assembled on an improvised slipway, and then hung and sheathed with a professional flooring. Bearing structures consist of two vertical and two horizontal profiles with a section of 40x40 mm, interconnected by means of overlapping triangular-shaped slopes. Bottom corners were set with bolts and tubes.
The gates and gates were hung on ready-made separate sheds, one part of which was pre-mounted to the posts. Frames were installed and fixed with wedges.The edge of the sheet was brought to the lower corner, after which he pressed against the upper corner removed at that time and riveted to them. After that, the gate was equipped with a bolt, and the gate - with an ordinary mortise lock.
Subsequently, a doorphone and a mailbox were installed at the entrance. In the process of work, the old fence was dismantled in parts, which made it possible not to bare the yard until the installation of a new fence. As a result of almost ten-day efforts, a pleasant and, apparently, very functional protective structure appeared. Metal profile fence is one of the most affordable and reliable types of fencing.
