Safety operation platform for steel box girder temporary support construction

Abstract

The invention discloses a safety operation platform for steel box girder temporary support construction. The platform comprises a plurality of stand columns arranged in two rows, a cross beam is installed at the top end of each row of stand columns, the two cross beams are horizontally arranged and parallel to each other, a web operation platform is laid above the cross beams, a web protection net is arranged on the periphery of the web operation platform, longitudinal beams are installed between the two rows of stand columns, the longitudinal beams are horizontally arranged and parallel to one another, a bottom plate working platform is laid on the longitudinal beams, and a bottom plate protective net is arranged on the periphery of the bottom plate working platform. Stable support is formed through the stand columns and the cross beam structures, the module lap joint and connection mode is simple, the modules can be integrally disassembled and turned over to be used next time after lap joint is completed, meanwhile, the double-layer operation platform is arranged, enough operation space is provided for operators, the construction environment is good, part of construction tools can be directly placed on the construction platform, and the construction efficiency of workers is high. Meanwhile, the protective net is arranged, so that the safety of the workers is guaranteed, the safety meets the construction requirements, and the high-place operation risk is reduced.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a construction safety work platform for a temporary support of a steel box girder. Background technique [0002] The steel box girder is an all-steel structure prefabricated box girder. When designing the steel box girder, it needs to be divided into sections due to the large span. When the beam section is not connected, the beam section is temporarily installed on the temporary steel structure support, and the beam section is removed after the connection is completed. After the steel box girder is hoisted on the temporary support, a safe working platform is installed on the basis of the existing temporary support steel structure. [0003] Among them, the longest beam section of the steel box girder is 50 meters in span, and the design is divided into three sections, each section is 16.7 meters, and the joints of the beam sections are welded by full-section penetration. The...

Problems solved by technology

[0004] However, the existing technology only uses steel pipes, section steel, etc. to build a simple platform, and the safety of the platform is low. Then, people work in hanging baskets, hanging baskets and other components. The working space is limited and the working efficiency is low.
