Large-span steel-concrete structure and its construction method

Abstract

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. A plurality of U-shaped stirrups are installed on a plurality of support structures, a template is installed in the U-shaped stirrups, a steel bar structure is arranged in the template, an auxiliary steel structure is installed in the steel bar structure, and the support structure includes a support body structure and a support seat structure , The support body structure includes a lifting upper column, the support seat structure is installed at the bottom end of the lifting upper column, and a height adjustment structure is installed between the support seat structure and the lifting upper column, and its support range can be adjusted, and the number of support structures is less required. The construction is more time-saving and labor-saving, and the support structure is a foldable structure, which has good coupling in use, and the connection between components is connected.

Description

technical field [0001] The invention relates to the technical field of shaped steel concrete structures, in particular to a large-span shaped steel concrete structure and a construction method thereof. Background technique [0002] At present, there are many large-span steel-concrete structures in high-rise buildings in the city due to the demand for use. The large-span steel-concrete structures have many advantages such as good overall stability, excellent seismic performance, space and material saving, so they are becoming more and more in the building. Adopted. [0003] Existing large-span steel-concrete structures generally include a reinforced frame, which is formed by welding or binding a large number of shaped steels. Templates are provided on the bottom and sides of the stirrups, and stirrups or wooden trusses are fixed to the outside of the template. The bottom end of the stirrup or the wooden beam is provided with a plurality of support columns, and the bottom end...

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
