Closed type cantilever scaffold system and construction method

Abstract

The invention discloses a closed type cantilever scaffold system and a construction method thereof. The closed type cantilever scaffold system comprises a cantilever steel beam through-wall structure,a cantilever steel beam balcony slab placement structure for containing a balcony slab and manufacturing a cantilever balcony, a closed type cantilever scaffold system for building a scaffold, and anoverhead cantilever formwork protective shed for erecting a protective shed, wherein the cantilever steel beam through-wall structure is used for through-wall fixing construction of a structural steel girder; an anchoring device adopting the cantilever steel beam through-wall structure is convenient to install and flexible to disassemble, the turnover utilization rate can be effectively increased, and an integrated high-intensity embedded U-shaped pull ring and an inclined strut steel tube shaping connecting beam piece are adopted, so that the balcony slab is effectively prevented from beingdamage by crushing, an adjustable vertical rod is adopted for compression joint of a fixing rod and a wall column reinforcing type connecting wall rod, the application range of the scaffold is enlarged, the overhead cantilever formwork dual-layer protective shed is adopted, safety risk in external frame erection is reduced, and safety construction is facilitated.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a closed cantilevered scaffolding system and a construction method, and is especially suitable for the construction of the closed cantilevered scaffolding system. Background technique [0002] In recent years, with the increasing number of urban buildings, the form of scaffolding is also showing a trend of diversification, and cantilevered scaffolding is widely used for its large operating range, material saving, low cost, simple and convenient erection, safety and reliability. usage of. The traditional cantilever frame uses steel pipes as the supporting mechanism, which has poor stability. In recent years, the cantilever frames all use section steel as the support. The fixing methods of the cantilever section steel beams are different. Usually, the requirements are not met, the construction is inconvenient and the stability is poor, the waste is large, and the cost investment i...

Problems solved by technology

[0005] The purpose of the present invention is to provide a closed cantilevered scaffolding system and construction method for the difficult problems encountered in the installation and protection construction of the existing cantilevered scaffolding system, and the adopted cantilevered steel beam through the wall structure The anchoring device is easy to install and flexible to remove, which can effectively improve the turnover rate and high utilization rate. It adopts integral high-strength pre-buried U-shaped pull rings and diagonally braced steel pipes to shape the connecting beams, which can effectively prevent the balcony slab from being crushed. Rod crimping fixed rod, wall column reinforced wall rod, broaden the scope of use of scaffolding, adopt high-altitude cantilever formwork double-layer protective shed, reduce the safety risk in the erection of the outer frame, and facilitate safe construction
