Large-span steel reinforced concrete structure and construction method thereof

Abstract

The invention relates to the technical field of steel reinforced concrete structures, in particular to a large-span steel reinforced concrete structure and a construction method thereof. The large-span steel reinforced concrete structure comprises a steel bar framework and a plurality of supporting frameworks; every two adjacent supporting frameworks in the multiple supporting frameworks are connected through a plurality of bolts; a plurality of U-shaped stirrups are installed on each of the multiple supporting frameworks; a formwork is installed in the U-shaped stirrups; the steel bar framework is arranged in the formwork; an auxiliary steel structure is installed in the steel bar framework; each supporting framework comprises a supporting body structure and a supporting seat structure; each supporting body structure comprises a lifting upper column; each supporting seat structure is installed at the bottom end of the corresponding lifting upper column; and height adjusting structures are installed between the supporting seat structures and the lifting upper columns. The supporting range can be adjusted, the number of the supporting frameworks is relatively small, the construction is relatively time-saving and labor-saving, the supporting frameworks are of foldable structures, the use coupling performance is relatively good, the parts are connected, the parts are not prone to being lost, meanwhile the supporting reliability is relatively high, and the practicability are relatively high.

Description

technical field [0001] The invention relates to the technical field of steel concrete structures, in particular to a large-span steel concrete structure and a construction method thereof. Background technique [0002] At present, there are many long-span steel concrete structures in the high-rise buildings in the city due to the demand for use. The long-span steel concrete structures have many advantages such as good overall stability, excellent seismic performance, and saving space and materials. Therefore, they are becoming more and more popular in construction. Adopted. [0003] Existing long-span steel-concrete structures generally include a steel bar frame, which is formed by welding or binding a large number of steel bars. The bottom surface and the outside of the side of the stirrups are provided with formwork, and the outside of the formwork is fixedly connected with stirrups or wooden beams. The bottom of the stirrups or wooden beams is provided with a plurality of...

Problems solved by technology

[0004] However, the installation of the supporting columns in the above construction process is laborious. At the same time, the demand for the supporting columns is large, and the construction is time-consuming. Moreover, the supporting columns and the flat supporting plates are independent structures, so the coupling is poor, and the supporting reliability is low. , less practical
