Embodiment 1

[0022] Schematic diagram of structural reinforcement of a structural unit of CFST-opened steel plate-concrete composite shear wall figure 1 , figure 2 with image 3 shown. There is no reinforcement in the steel pipe concrete frame column 1; the frame beam of the shear wall is the longitudinal reinforcement 6 of the frame beam arranged around the steel beam 3; holes are opened on the steel plate 2 of the shear wall, and the opening form is shown in the figure. The reinforcement of the shear wall panel is: on both sides of the width direction of the wall panel, the transverse reinforcement 4 and the longitudinal reinforcement 5 of the shear wall panel are evenly arranged horizontally and vertically respectively, and are bound and fixed at the intersection points to form two pieces of reinforcement mesh. The transverse reinforcement 4 is inserted into the concrete-filled steel pipe frame column 1 (perforated on the side wall of the column) for anchorage; finally, the frame col...

Abstract

The invention discloses a steel pipe concrete-holed steel plate-concrete combine shear wall and making method thereof, belonging to the field of building construction. The steel pipe concrete-holed steel plate-concrete combine shear wall is characterized in that: the shear wall is composed of steel pipe concrete frame columns (1) and steel plate concrete shear wall boards; a steel plate embedded in the shear wall is provided with an opening, the two sides of the steel plate (2) are provided with steel bar nets composed of transverse steel bars (4) and longitudinal steel bars (5), and the steel bar nets at two sides of the steel plate (2) are tied by steel tie bars (7) at the opening. Compared with the conventional shear wall, the shear wall of the invention has large initial rigidity, high bearing ability, slow attenuation for bearing force and rigidity, good whole shock resistance and energy consumption performance, stable shock resistance performance, and reduced bottom shearing sliding destroy.

Description

technical field [0001] The invention relates to a composite steel pipe concrete-opening steel plate-concrete shear wall and a manufacturing method thereof, belonging to a shear wall and a manufacturing method thereof. Background technique [0002] With the development of social production and the needs of people's lives, there are more and more high-rise buildings. Reinforced concrete high-rise buildings with large volume and wide area are usually composed of beams, columns, floors, shear walls and cylinders. The shear wall and the cylinder composed of the shear wall are the core parts of the high-rise building's seismic resistance, and the seismic performance of the shear wall structure plays a vital role in the safety and reliability of the high-rise building. Especially in recent years, there are more and more large and complex high-rise buildings pursuing individualization, and the seismic performance requirements for shear walls and cylinders composed of shear walls ar...
