Multi-purpose lossless quick mounting and dismounting edge protection net

Abstract

The invention discloses a multi-purpose lossless quick mounting and dismounting edge protection net, and belongs to the technical field of construction protection equipment. The protection net comprises hollow transverse square steel pipes with holes, hollow vertical square steel pipes with holes, short square steel pipes with holes and a steel wire mesh, the steel wire mesh is welded into a square frame structure, the hollow transverse square steel pipes with holes, the hollow vertical square steel pipes with holes, the short square steel pipes with holes and the steel wire mesh jointly form protection net structures, and the adjacent protection net structures are connected through connecting auxiliary pieces. According to the protection net, large objects can be effectively prevented from falling off from an elevator shaft opening or the edge of a floor, impact damage of the objects is effectively prevented, no damage is caused to a concrete wall body when the protection net is mounted and dismounted, lossless mounting and dismounting can be thoroughly achieved, and the protection net has the structural characteristics of convenience in mounting and dismounting and flexible and changeable combination modes.

Description

technical field [0001] The invention relates to the technical field of construction protection equipment, and more specifically, relates to a multi-purpose non-destructive rapid installation and removal of the edge protection net. Background technique [0002] At present, the following two methods are usually used as protection at the entrance of the elevator shaft and the edge of the floor on the construction site: (1) steel pipes are used as railings, and the two steel pipes are fixed to the shear wall of the elevator shaft or the edge of the floor with buckles and expansion screws shear wall. (2) Use expansion screws to fix the finished guardrail to the shear wall at the entrance of the elevator shaft or the shear wall at the edge of the floor. The first protection method is to use two steel pipes as protection. Due to the large distance between the steel pipes, effective protection of personnel cannot be achieved; due to the large distance between the two steel pipes fo...

Problems solved by technology

The first protection method is to use two steel pipes as protection. Due to the large distance between the steel pipes, effective protection of personnel cannot be achieved; due to the large distance between the two steel pipes for steel pipe railing protection, it cannot prevent objects from passing through the elevator shaft and the edge of the floor Dropping can easily cause damage to objects; at the same time, the method of fixing with expansion screws has caused additional secondary damage to the shear wall, and the way of drilling holes to place expansion screws is time-consuming and laborious

The second protection method, although it can better protect the elevator shaft opening or the edge of the floor on the floor that has been completed and the formwork has been removed, it cannot effectively protect the elevator shaft opening and the edge of the floor on the construction floor of the main structure. Edge protection; at the same time, the same as method 1, the method of fixing with expansion screws caused additional secondary damage to the shear wall, and the way of drilling holes to place expansion screws was time-consuming and laborious
