Overall dimensions of pipes
When installing a fence of profiled sheeting, basically, two types of pipes are used:
- pipes with a classical circular cross-section, or profile, which are installed as vertical supports;
- cut square or rectangular section of the pipe, for the installation of horizontal logs.
Thus, when installing a fence of pipes can significantly save by applying a different thickness of the pipe. For poles, more overall pipes are purchased in comparison with thin-walled lags.
When mounting a fence whose height exceeds 2 m, a pipe diameter of 80 mm is used as a post, and if a fence of 2 meters and less is planned, 60 mm in diameter.
Because of the high cost, round pipes are very rarely used for fences. Basically, a profile material with the following parameters is used:
- 80mm * 60 mm - for fences with a height of more than 2 meters;
- 60mm * 40mm - for fencing in 2 meters and below.
The number of supports necessary for the installation of the fence is calculated along the perimeter of the fence. The distance is divided by the distance( the distance between the columns) and we get the desired number. Professionals recommend using a step of 2 meters. The length of the pole is taken by 30% more, the planned height of the fence. This is the size of the part of the pipe that is mounted under the ground.
To connect the columns use a profile pipe cut in half, so the fence shield itself is easier to attach to it than to the round one. For this purpose, take a tube with dimensions of 20mm * 40mm, for any height of the fence. When installing a fence with a height of up to 2 m between the supports, two lags are mounted, and for a larger value, three lags are installed. This is due to the fact that the sheet of corrugated sheet can bend under the influence of wind. Depending on the desired height, the number of horizontal elements is calculated - the perimeter of the fence is multiplied by two, or three.
Mounting of vertical supports
Builders use four methods of installing a pipe for ground sampling:
- can drill a shaft of the required length with a drill, immerse a vertical support in it. To fix the pipe use a concrete solution. The disadvantage of this method is the time it takes to solidify the concrete;
- as a filling, in the prepared trench, you can use small gravel and fill it with a pipe. Only the stability of such a support will be questionable;
- can be welded to the end of the pipe drill column with blades and screw this structure into the ground. This is a very effective, but expensive way of installing poles for fence;The
- support can simply be hammered into the ground, only with this technology it is possible to damage the outer end of the pipe and the deviation of the post from the vertical.
The height of the supports is controlled by the hydraulic level, the step distance is measured by a measuring rope, which is stretched between the columns.
Installation of horizontal logs
You can mount the logs on the installed vertical posts in three ways:
- overlapping - the horizontal frame element is welded or screwed to the vertical support with screws;
- butt-lag assembly is welded to the stand, forming a T-joint. This method is not applicable for round pillars;
- using slotted grooves - in the pole make a special groove in which the lags are installed. Fastening of elements among themselves is carried out by welding.
On the fence frame installed from the pipes, the corrugated sheets are fastened around the perimeter. The installation of the sheets starts from any column and controls the height of the shields along the adjacent sheet.
