Construction method of deep beam steel support in transfer layer

Abstract

The invention provides a construction method of deep beam steel support in a transfer layer, and belongs to the field of building engineering construction. The construction method of the deep beam steel support in the transfer layer comprises the steps that S1, construction information is obtained, and a plurality of supporting devices are prepared according to the construction information; S2, each supporting device is installed on two sides of the lower part of a deep beam; S3, supporting steel bars are arranged, the supporting steel bars are fixed to the supporting devices, and the positions of the supporting steel bars are adjusted; S4, steel bar structures on the upper part of the deep beam are sequentially installed on the steel bars; S5, U-shaped bolts of the supporting devices andthe supporting steel bars are dismantled; and S6, the parts of the supporting devices which exceeds a pouring elevation are removed, and concrete on the deep beam is poured after acceptance is qualified. According to the construction method, welding is replaced by arranging the plurality of supporting devices, the problems that the welding seam quality is not qualified, the welding speed is low, and the structure cannot be adjusted after welding are avoided, therefore the mounting quality and the working efficiency are improved, and materials are saved.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and in particular relates to a construction method for the support required for binding steel bars during the construction of a deep beam structure in a transfer floor. Background technique [0002] Most of the transfer floors of high-rise or super-high-rise buildings are mass concrete structures, and the "layered and segmented" construction method is generally adopted, and each layer is constructed according to the procedures of steel bar binding, formwork installation, and concrete pouring. The transfer layer structure is generally composed of deep beams or slabs, and the upper and lower layers of deep beams or slabs often have the characteristics of large number, large diameter, and heavy weight. After the concrete pouring of the lower layer is completed for the deep beam of the transfer layer, there is often a technical problem that it needs to provide support for the upper la...

Problems solved by technology

Regardless of the construction method of processing large-diameter steel bars into stirrups or welding them into steel support frames, there is a large amount of material consumption and it is difficult to realize the reuse of support materials. At the same time, it is difficult to adjust the installation height of stirrups or support frames flexibly. Assembling the support frame requires time and cost and other difficulties, so it is difficult to meet the requirements of on-site construction
