A multi-purpose non-destructive rapid installation and disassembly of the edge protection net

Abstract

The invention discloses a multi-purpose non-destructive rapid installation and disassembly of a border protection net, which belongs to the technical field of construction protection equipment. The invention comprises hollow horizontal square steel pipes with holes, hollow vertical square steel pipes with holes, short square steel pipes with holes and steel wire mesh, the inner welding of the square frame structure is provided with steel wire mesh, the hollow horizontal square steel pipes with holes and the hollow belt The vertical square steel pipes with holes, the short square steel pipes with holes and the steel wire mesh together constitute the protective net structure, and the adjacent protective net structures are connected by connecting auxiliary parts. The invention can effectively prevent large items from falling from the elevator shaft or the edge of the floor, and can also effectively prevent objects from being hit and hurt. The installation and removal of the protective net will not cause any damage to the concrete wall, and can be completely finished. From non-destructive installation and dismantling, it has the convenience of installation and dismantling and the structural characteristics of flexible and changeable combination methods.

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
