Problems solved by technology

Although the CFST composite column has good energy dissipation capacity, when it is used as the frame column of the shear wall, the ductility of the reinforced concrete wall panel in the shear wall as the first line of defense is poor, which affects the entire shear force. The lateral force resistance of the wall and the entire structure, that is, the seismic capacity

Embodiment 1

[0030] The schematic diagram of structural reinforcement of a structural unit of a composite frame-steel brace-concrete composite shear wall is shown in figure 1 , Figure 2 and image 3 shown. Concrete-filled steel tube core columns are arranged inside the concrete-filled steel tube composite columns 3; the frame beams of the shear wall are longitudinal bars 7 arranged around the steel beams 4, and rectangular stirrups 8 are evenly bound along the longitudinal bars 7 of the beams, and the rectangular stirrups 8 of the frame beams are Evenly distributed to the beam end; the reinforcement of the shear wall panel is: on both sides of the width direction of the wall panel, the transverse reinforcement 5 and the vertical reinforcement 6 of the shear wall panel are evenly arranged in the horizontal and vertical directions respectively, and are bound at the intersection fixed to form two pieces of steel mesh, the two ends of the horizontal steel bar 5 and the vertical steel bar 6 ar...

Embodiment 2

[0040] The second structural form of composite frame-steel brace-concrete composite shear wall is as follows: Figure 4 As shown, the X-shaped steel concealed support 2 is set inside the two steel meshes of the shear wall panel, and its upper end extends into the joint between the steel tube concrete composite column 3 and the upper frame beam, and connects with the steel tube concrete composite column 3 and the upper frame. The beams are medium-sized steel beams with 4 connections. The lower end extends into the joint between the concrete-filled steel tube composite column 3 and the lower frame beam, and is connected with the concrete-filled steel tube composite column 3 and the medium-sized steel beam 4 of the lower frame beam. Other aspects are the same as the first form.

Embodiment 3

[0042] The third structural form of composite frame-steel brace-concrete composite shear wall is as follows: Figure 5 As shown, the eight-shaped steel concealed support 2 is set inside the two steel meshes of the shear wall panel, and its upper end extends into the upper frame beam to connect with the beam medium-sized steel beam 4, and its lower end extends into the steel pipe concrete composite column 3 and the lower frame Among the nodes of the beam, it is connected with the concrete-filled steel tube composite column 3 and the medium-sized steel beam 4 of the lower frame beam. Other aspects are the same as the first form.

Abstract

The invention relates to a laminated frame-steel support-concrete combine shearing wall and manufacturing method thereof. The shearing wall is composed of a frame and shearing wall boards. Steel bar nets arranged in double directions are arranged in the shearing boards, steel tie bars (11) are arranged between the steel bar nets, and a section steel concealed bracing (2) is arranged between two rows of steel bar nets. The shearing wall is characterized in that the frame beam is provided with a section steel beam (4), the frame columns at the two ends of the shearing wall are provided with steel pipe concrete laminated posts (3), and the section steel beam (4), the steel pipe concrete laminated posts (3), and the section steel concealed bracing (2) combine to form a concealed steel truss in the concrete shearing wall; and the section steel concealed bracing combination can be in herringbone, X shape or splay. Compared with the conventional shearing wall, the shearing 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 frame-steel brace-concrete composite 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 are also getti...
