Embodiment

[0031] Such as figure 1As shown, this embodiment is used in the Chengwen Road Reconstruction Project in the Chengdu Second Ring Road Reconstruction Project to slow congestion and maintain smoothness in the central urban area. Wen Road), the project starts from the Chengwen Overpass on the Second Ring Road in the east, passes through South Shuangqing Road, Jinsha Station, Qingyang Avenue, West Qingjiang Road in the west, and ends at the east side of the Supo Overpass on the Third Ring Road in the west, with a total length of about 2.1 kilometers , the construction mileage is K1+705-K1+920 (that is, the main pier 43#-48#), located in the center of the original Chengwen Road, crossing Qingyang Avenue (2.5 Ring Road), Qingjiang Middle Road Subway Station of Metro Line 4 (with the subway Line 7 transfer station) is located in this section; Qingjiang Middle Road Subway Station of Metro Line 4 (transfer station with Metro Line 7), the station length is 205.2m, the maximum width is 26...

Abstract

The invention discloses a steel truss cantilever support and an implementation method thereof. The steel truss cantilever support comprises a plurality of support columns on a bearing platform. A steel truss is mounted at the top of each support column. A workbench is hung on the outer side of each support column and below the steel truss. Due to the fact that the steel truss is mounted at the top of each support column, the workbenches can be hung below the steel truss, pier form plates can be mounted on the workbenches, the weight of the form plates are hung and supported by the steel truss, compared with the method that a scaffold is set at the bottom of a full frame, the method that the workbenches are hung below the steel truss can reduce overall floor space, certain space can be reserved below the workbenches to allow vehicle passing, protecting devices can be mounted below the workbenches to guarantee safety, safety passing is achieved, floor space of scaffolds is reduced greatly, overall hanging time and demounting time of the steel truss cantilever support are much less than building time and demounting time of full frame scaffolds.

Description

technical field [0001] The invention relates to an auxiliary tool for building construction, in particular to a steel truss suspension bracket and a realization method thereof. Background technique [0002] Pier column, that is, the lower load-bearing object used to carry the upper structure in civil engineering. Most of the cross-sections of piers are circular, and there are also heterosexual piers such as ellipse, square, curve, and parabola. It is an important part of highway bridges, railway bridges, sidewalks and other bridges, overpasses, ramp bridges, flyovers and other projects. [0003] The pier column construction of the current viaduct or overpass is usually carried out according to the following procedures: construction of excavated piles, foundation cap construction, construction of the lower part of the pier column, erection of scaffolding, construction of steel bars, installation of pier formwork on the scaffold, concrete on the upper part of the pier column ...
