Weld Mesh Fence used in high-rise buildings requires the national standard for safety nets (GB5725-85). The first building protective mesh fence is generally hung on the second floor (3-4m height), and then hang another movable building protective net every 6-8m (GB5725-85 regulations). In addition to a fixed building mesh fence on the second floor of a multi-storey or high-rise building, a fixed safety net should be installed every fourth floor. The distance between the net and the surface of the object below (or on the ground) shall not be less than 3m.
When setting up the building mesh fence, it should be considered in advance that there should be a retractable movable building protective net at the temporary position where materials need to be fed in and out. A safety fence must be hung under the working part at a high place; when the height of the building exceeds 4m, a safety net that gradually rises with the wall must be installed, and a fixed safety net must be installed every 4m in the future; , Safety nets must be set at the upper and lower holes.
The erection of the safety mesh fence should be low on the inside and high on the outside, and the height difference of the expenditure part is generally about 50cm; the supporting rods should not be broken or bent; the gap between the inner edge of the net and the wall should be less than 15cm; the distance between the lowest point of the net and the surface of the object below should be greater than 3m . For the support used for erecting the safety net, the diameter of the small end of the wooden pole shall not be less than 7cm, the diameter of the small end of the bamboo pole shall not be less than 8cm, and the distance between the poles shall not be greater than 4m.
