Problems solved by technology

The first method is obviously uneconomical, and the effect of showing the facade is not ideal; while the second method is less safe
[0003] When working on high-altitude cantilevered external scaffolding, in order to prevent falling from high places, a cantilevered protective net is often used to connect with the cantilevered external scaffolding as a horizontal protection for the periphery of high-rise building structures. However, the construction of this traditional horizontal protection is complicated and the construction process is difficult Long, not conducive to the purpose of efficient construction of the project

Embodiment

[0022] A construction method for rapid assembly and disassembly of a horizontal pick net of a high-altitude cantilevered outer frame, refer to Figure 1-4 , including the following steps:

[0023] S1. Horizontal pick net assembly: Assemble horizontal pick net 1 on the ground. Ordinary steel pipes of φ48mm can be used. The main frame is erected vertically and then horizontally. The length varies from 3 to 6m, depending on the vertical length of the roof structure. The width is the length of the outside pick. It can be 3m, and the vertical and horizontal spacing can be 1.5m. It can be assembled into a "field"-shaped horizontal structure, and then hang safety nets and white nets. 30mm flat net, you can first lay a flat net pocket bottom on the main frame, and then lay a dense mesh net, and use 22# wire to bind and fix, and use 0.8m poles on both sides of the horizontal pick net 1 to erect several vertical connecting rod 2;

[0024] S2. Hoisting of horizontal pick nets: The roof...

Abstract

The invention provides a construction method for quickly assembling and disassembling a horizontal overhanging net of a high-altitude overhanging outer frame. The construction method comprises the steps of assembling the horizontal overhanging net, hoisting the horizontal overhanging net, fixing the horizontal overhanging net, disassembling the horizontal overhanging net and the like. In the construction process, an operator can achieve rapid assembly and disassembly construction, risks are avoided, meanwhile, labor input is reduced, the safety construction requirement is met, the high-altitude falling risk is effectively prevented, operation is very convenient, disassembly and recycling can be achieved after use, the recycling rate reaches 100%, the use cost is extremely low, the safety protection measure cost is greatly reduced, and the safety protection effect is good. The economic and technical benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of high-altitude cantilevered outer frame picking nets, in particular to a construction method for rapid assembly and disassembly of high-altitude cantilevered external frame horizontal picking nets. Background technique [0002] Preventing falls from heights is the focus of safety management on construction sites, especially in the construction phase of the main structure of high-rise buildings. The roof of the high-rise residential building is designed with overhangs, the length of the overhang is 1.2m, and the main structure is constructed with climbing frame + aluminum formwork. Continue to climb to the roof. There are two options for the construction of the outer frame: the first is not to dismantle the climbing frame, and the cantilever frame is erected above the climbing frame; the second is to dismantle the climbing frame first, and then build the cantilever frame. The first method is obviously une...
