Upper air anti-collision guardrail module transfer hanging bracket and construction method

Abstract

Provided are an upper air anti-collision guardrail module transfer hanging bracket and a construction method. The module transfer hanging bracket comprises a sliding rail on a viaduct bridge and a walking car provided with a plurality of counter weights and inner trusses. The plurality of inner girders are longitudinally connected through connecting rods, and each inner girder is connected with an outer girder with a guard railing through an oblique beam, an upper beam and a lower beam. The outer girder is suspended outside a bridge floor, the lower portion of the outer girder is connected with a horizontal frame, and a slide on the upper beam is slidingly connected two slide bodies connected with electric blocks and steel moulding plate hooks. The plurality of outer girders and horizontal frames are connected through footboards to form an anti-collision guardrail module transfer hanging basket which can enable ten (or more than ten) persons to conduct steel moulding plate concrete pouring operation simultaneously, and movement of a steel moulding plate saves time and is convenient and short in time. An operating platform is reasonable in structure, firm and stable, and workers are safe in working high above the ground. The upper air anti-collision guardrail module transfer hanging bracket is connected through bolts, is convenient in assembly and capable of using in a turnover mode, needs to occupy no roads by adopting the upper air anti-collision guardrail module transfer hanging bracket and the construction method, does not influence passing of vehicles under bridges, and has obvious economic benefits.

Description

technical field [0001] The invention relates to a construction method for an anti-collision guardrail of a viaduct, in particular to a mold-moving hanger and a construction method for a high-altitude anti-collision guardrail of a viaduct. Background technique [0002] The traditional method used in the construction of the anti-collision barriers on both sides of the viaduct is to set up double-row scaffolding operating platforms under the viaduct, but in the construction of urban viaducts, due to the impact of heavy traffic flow, there is no condition to erect double-row scaffolding. [0003] Chinese Patent No. 201020217577.5 discloses a "Mobile Rotary Crane for Bridges with Hanging Eaves Cast-in-place Concrete Anti-collision Guardrails", which provides a hanger connected with a workbench through a rotating shaft on a traveling vehicle, and the working The back end of the table is equipped with hoist and counterweight technology. In this technology, the manual rotation hang...

AI Technical Summary

Problems solved by technology

The patent mentioned the problem of insecure construction in the past in the background technology, but the patent only provides a 360° rotating workbench to hook the formwork to the formwork with the hook, and the manual operation of the hoist to control the formwork height is convenient for workers to install and operate. The working face still adopts the previous unsafe structure when workers operate, and no technical solution has been given

In addition, only one steel formwork can be disassembled and assembled at a time using the above-mentioned technology, and the progress of the project is slow.
