Steel frame-reinforced masonry shear wall composite structure and construction method thereof

Abstract

The invention discloses a steel frame-reinforced masonry shear wall composite structure and a construction method thereof. The steel frame-reinforced masonry shear wall composite structure consists of a steel frame, reinforced masonry shear walls and floor slabs, wherein the steel frame is formed by welding steel frame columns and steel frame beams or connecting the steel frame columns with the steel frame beams by bolts; each reinforced masonry shear wall is formed by building blocks, mortar and grout concrete; the reinforced masonry shear walls are connected with the steel frame through vertical reinforcing steel bars in the reinforced masonry shear walls to form a whole. The concrete structure is that the overall shape of each steel frame beam is a rectangular cavity; holes are formed in the upper surface and the lower surface of the cavity of each steel frame beam; the positions of the holes are overlapped with the holes of each building block of the adjacent reinforced masonry shear wall; the vertical reinforcing steel bars pass through the holes of each steel frame beam and the holes of each building block; holes of the building blocks and the cavities of the steel frame beams are filled with the grout concrete The steel frame-reinforced masonry shear wall composite structure has the advantages of high anti-seismic property, quick construction, low comprehensive cost, excellent fire resistance, application to a structure system with large span and large space, and the like.

Description

technical field [0001] The application belongs to the field of civil engineering, and in particular relates to a steel frame-reinforced masonry shear wall composite structure and a construction method thereof. Background technique [0002] Steel structures are widely used in high-rise buildings, large-span and large-space structures, factory buildings and other buildings. It has the following advantages: fast construction, no damage to forest resources, clean and environmentally friendly, no harmful substances, good seismic performance, recyclable, labor-saving, flexible design, and easy access to large spaces and large spans. However, the rigidity of the steel structure is not as good as that of the concrete structure and the masonry structure. It is a flexible structure, and the lateral displacement is relatively large under the action of the lateral load, which affects the comfort of use; The property softens and collapses, and finally the steel structure.

AI Technical Summary

Problems solved by technology

However, the reinforced masonry structure is not conducive to obtaining a large space and a large span. At the same time, it has a large rigidity, a large self-weight, and a large seismic load during an earthquake, which is not conducive to earthquake resistance.
