Embodiment

[0022] Such as figure 1 As shown, there is no safety net fixing point in the center of the ceiling of the installation hall, and there is a double row of floor-to-ceiling scaffolding at the central mast 1 of the installation hall, which is mainly used to fix steel wire ropes and hang dense mesh safety nets.

[0023] Install steel wire rope 2 and counterweight, install 58 steel wire ropes with a length of 85000mm at the position of the pressure bar on the side of the central mast 1, one end is fixed with a U-shaped buckle around the pressure bar, and the other end is pulled by a small hoist to the outer ring beam of the cornice main structure 4 And hang down to the ground, hang the cement counterweight 3 at the lower end, each counterweight is 250kg, a total of 8 pieces, use electric hoist to lift, after reaching the specified height, fold the lower end of the steel wire rope 2 to a length of 650mm, and connect it firmly and reliably with U-shaped buckles. There are three U-sha...

Abstract

The invention relates to a method for assembling a large-area safety net. The method comprises the following steps: 1) building a row of floor type cross scaffolds in the center of an assembly hall; 2) assembling a steel wire rope and a counterweight, wherein one end of the steel wire rope is fixed with a central scaffold pole through a U-shaped buckle, while the other end is towed to the outside of a main body structure through a small hoist to drop to the ground, and the tail end suspends the cement counterweight; 3) sleeving a side rope of the safety net on the stretched steel wire rope by using a safety clasp; 4) binding a hemp rope at the upper end of the side rope of the safety net, and towing the upper end of the safety net to the central scaffold pole by a hemp rope through a fixed pulley; 5) binding and fixing the hemp rope with the central scaffold after the safety net is in place; and 6) binding and fixing the side rope between adjacent net pieces with the steel wire rope in the center from the top to bottom. Compared with the prior art, the method has the advantages of solving the problems of stretching and suspending the safety net under the condition of not building the scaffold and the like.

Description

technical field [0001] The invention relates to a safety net installation method, in particular to a large-area safety net installation method. Background technique [0002] Safety nets are used to prevent people and objects from falling, or to avoid falling and object damage. They are divided into flat nets, vertical nets and dense mesh safety nets. The common specifications of safety nets are 1.8 meters wide and 6 meters long. Now Dense-mesh safety nets are widely used, and the standard of dense-mesh safety nets: there are more than 2,000 meshes in an area of ​​100 square centimeters, the resistance to penetration test, the angle between the net and the ground is 30 degrees, and 5 kg of φ48MM steel pipes are placed at a height of 3 meters. free fall and impenetrable. The connection of conventional safety nets is spliced ​​by nylon ropes and must be fixed on the scaffolding. There are many fixing points, and the assembled safety nets are prone to poor splicing and potentia...
