Construction method for inclined tensioning reinforcing bar type and overhanging section steel scaffold

Abstract

The invention discloses a construction method for an inclined tensioning reinforcing bar type and overhanging section steel scaffold. The construction method comprises the following steps that a load is borne in an inclined tension manner, one end of an inclined tensioning reinforcing bar is fixedly arranged on welded angle steel on the end part of overhanging section steel through a sleeve, the other end of the inclined tensioning reinforcing bar is connected onto a reinforcing bar pre-embedded in an upper structure through a sleeve, and the inclined tensioning reinforcing bar is used for bearing the load. According to the construction method, the most common materials are utilized, a scaffold can be erected in a short period, according to a series of structural measures, the requirement on bearing force and stability is met, and by fully utilizing the performance of current materials and greatly saving cost, an excellent construction effect and economic benefits are achieved.

Description

technical field [0001] The invention relates to a construction method of scaffolding, in particular to a construction method of steel bar cable-stayed section steel cantilevered scaffolding. Background technique [0002] For the erection of section steel cantilever formwork scaffolding in the construction of cantilever structures, the traditional methods include single-section steel cantilever support, wire rope cable-stay and steel truss brace. Single-shaped steel cantilever steel has low rigidity, and if the overhang is large, the deflection will increase, which will cause large deformation of the bracket, so it can only be used in structures with small overhangs; the steel wire rope in the cable-stayed wire rope is a flexible material, and the force is uneven Or it is easy to be unstable due to the influence of the external environment, and the fixed end is easy to break the wire. After the construction is completed, the recycling rate of the steel wire rope is low. Con...

AI Technical Summary

Problems solved by technology

The rigidity of the single-shaped steel cantilevered steel is small. If the deflection increases when the cantilever is large, it will cause a large deformation of the bracket, so it can only be used in structures with small cantilevered structures; the steel wire rope in the cable-stayed cable is a flexible material, and the force is uneven. Or it is easy to be unstable due to the influence of the external environment, and the fixed end is easy to break the wire. After the construction is completed, the recycling rate of the steel wire rope is low; the structure of the steel truss diagonal bracing is complicated, the construction technology is high, the steel price is expensive, and the construction cost is high.
