Novel assembling method for bent cap bearing frame

Abstract

The invention relates to a novel assembling method for a bent cap bearing frame without a full framing. Steel pipes with the sizes of Phi 400*7 mm and Phi 277*6.5 mm and I56 I-beams are used for manufacturing trusses; steel pipes with the size of Phi 400*7 mm are used for manufacturing bearing vertical uprights; the trusses and the vertical uprights are connected through high-strength bolts. the two trusses are connected by using precision rolling deformed steel bars and [28 channel steel therebetween; the trusses and the vertical uprights are clasped with reinforced concrete upright posts by using [20 channel steel; the bent cap load is transmitted to the trusses, the vertical uprights, a bearing platform and a pile foundation through bottom die distribution beams at the top of the trusses. According to the novel assembling method for the bent cap bearing frame, the reinforcement processing is carried out without a foundation, vertical uprights are few, the occupied area of the ground is small, an overall processing manner is adopted, the work amount of manual operation for installation is less, and the installation is simpler.

Description

technical field [0001] The application of the present invention relates to an important equipment device used in bridge construction, and is suitable for a cover beam load-bearing frame of a viaduct that does not require a full support. Background technique [0002] Generally, when the bridge viaduct cover girder is erected, steel pipe scaffolding, formwork and concrete load-bearing supports need to be erected underneath. Therefore, it is necessary to deal with the foundation, erect and disassemble the steel pipe scaffolding and load-bearing supports, and manage a considerable number of steel pipes on site. When there are rivers, roads or other obstacles under the cover beam, steel pipe scaffolding, formwork and concrete load-bearing supports cannot be erected. [0003] Process special cover beam brackets, the load-bearing part mainly includes poles and trusses, the poles stand on the cap, and the upper part of the poles uses trusses to transfer the load of the cap beam rein...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the disadvantages of the existing traditional full hall support, such as rivers, traffic roads and other obstacles under the construction projection surface of the cover beam, the support foundation and ground transportation are relatively difficult, and there are many rods and cumbersome construction. This application provides a cover beam load-bearing frame that does not require full support, does not require foundation reinforcement, and has a small number of vertical poles, takes up less space on the ground, adopts integral processing, and has less manual work for installation and is easier to install
