Setting method and function of building safety net

1. The external scaffold mostly used for high-rise building construction shall be set vertically, and the outer side shall be covered with safety net. Generally, the safety net woven with fine nylon rope shall be used. The safety net shall be tightly sealed and firmly fixed with the external scaffold

2. Horizontal safety net horizontal safety net is mostly used for the external scaffold of multi-storey building construction. It is woven with hemp rope, palm rope or nylon rope with a diameter of 9mm. The general specification is 3M wide, 6m long and about 5cm mesh. Each supported safety net shall be able to withstand an impact load of not less than 1600n. A safety net shall be set from the second floor to every 3 ~ 4 floors upward, and another safety net shall be set up along with the construction height. It is required that the net rope shall not be damaged, the rooting shall be firm, tight, tightly looped and tightly spliced, and the scaffold steel pipe shall be used for the support rod of the net bar. The net width shall not be less than 3m, and the minimum net width of one layer shall be 6m.

3. Erection method of horizontal safety net

(1) Using the external wall window frame support method, the cross bar 1 shall be placed in the wall of the upper window and bound firmly with the inner span of the safety net, the cross bar 2 shall be placed outside the wall of the next window to keep the old with the inclined bar of the safety net, the cross bar 3 shall be placed in the wall and bound firmly with the cross bar 2, and the distance between the inclined bars supporting the safety net shall not be greater than 4m.

(2) Steel suspenders can be used to erect safety nets. For walls without windows, steel suspenders can be used to erect safety nets. Holes shall be reserved on the wall, pins shall be inserted, wedged with pins, and there shall be holes on the locking plates Ф 14 holes for hanging boom safety net, and the steel boom is Ф 12 reinforcement, about 1.56m long, hook at the upper end, and a hook is welded on the back of the hook to hang the safety net. The lower end is welded with a movable hinge seat for installing a diagonal rod and a support foot against the wall. A wallboard and a ring for hanging nylon rope are also welded near the hook (hook) at the upper end. The function of the wallboard is to ensure that the suspender will not be damaged after being stressed. The spacing of suspenders is generally 3 ~ 4m.

(3) The first floor long-span safety net the first floor long-span safety net can be set up with fir diagonal bracing or set up on one side. Building protection net vertical net: in real estate buildings, in order to prevent high-altitude building materials and construction personnel from falling, the building is surrounded by building protection vertical net to avoid casualties.

Purpose: it is mainly used to prevent people and objects from falling or to avoid and reduce the injury caused by falling objects, protect the safety of high-altitude operators and pedestrians and maintain the cleanness of the construction site.
