Elevator shaft anti-falling net structure and construction process thereof

Abstract

The invention relates to an elevator shaft anti-falling net structure and a construction process thereof. The elevator shaft anti-falling net structure comprises an anti-falling net and connectors, wherein the four sides of the anti-falling net are provided with connecting rings; each connector comprises a connecting bolt and a casing pipe which are cooperatively connected; one end of each connecting bolt is provided with a connecting ring hanging groove; the other end of each connecting bolt is provided with an outer thread and connected with a nut. The casing pipes are inserted into originalformwork screw rod reserved holes of an elevator shaft, and the connecting rings are arranged on the connecting ring hanging grooves and are tightly matched and fixed by the casing pipes. By applyinga limiting structure and adopting the original formwork screw rod reserved holes of the elevator shaft as connecting points, the steps of pre-embedding reinforcing steel bars, inserting expansion bolts and the like are omitted, the casing pipes are pushed into the elevator shaft from the outside through the connecting bolts, the connecting rings on the anti-falling net are hung into the connecting ring hanging grooves, and then the connecting ring hanging grooves are sleeved with the casing pipes to ensure the structural stability. During construction, constructors do not need to enter the elevator shaft for construction, so that the effects are achieved that the construction process is simple and convenient, construction is safe, and the strength is reliable.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an elevator shaft anti-falling net structure with simple structure, convenient construction procedure, safe construction and reliable strength and a construction process thereof. Background technique [0002] In building construction, there are many potential safety hazards in the elevator shaft. Therefore, for the protection of the elevator shaft, various construction units have adopted various methods. For example, the traditional use of hard fall prevention measures requires multiple processes such as erecting the frame, installing, and laying scaffolding. During the installation of the frame, the operator needs to enter the elevator shaft for construction, and working at heights has certain risks. Its structure is relatively complex, the installation is difficult, and the installation time is long; and the hard fall prevention measures will cause sec...

For example, the traditional use of hard fall prevention measures requires multiple processes such as erecting the frame, installing, and laying scaffolding. During the installation of the frame, the operator needs to enter the elevator shaft for construction, and working at heights has certain risks. Its structure is relatively complex, the installation is difficult, and the installation time is long; and the hard fall prevention measures will cause secondary injury to the falling person, and cannot guarantee the personal safety of the falling person, and the long-term use of turnover materials such as steel pipes will increase the project cost; There are also common anti-falling nets, but the connection between them and the elevator shaft is relatively poor, and the construction is too difficult and dangerous, so it is not popularized and applied
