Embodiment 1

[0032] Schematic diagram of the structural reinforcement of a structural unit of steel tube concrete-steel braces-steel plate-wrapped concrete shear wall is as follows figure 1 , figure 2 and image 3 shown.

[0033] The production method is as follows:

[0034] 1) Fabricate steel pipe concrete frame column 1, install partitions inside steel pipes at beam-column joints, weld short steel beams outside the columns, and pre-weld vertical plates on steel pipe walls to prepare for anchoring steel plates 2 embedded in wall panels, and reserve The hole is used for anchoring the transverse reinforcement 5;

[0035] 2) Make the profiled steel beam 4 in the frame beam, the edge of the profiled steel beam 4 is welded to the flange of the preset short steel beam at the column edge, and the web of the steel beam and the web of the short steel beam are rubbed with double splint high-strength bolts type connection;

[0036] 3) Making the steel plate 2 embedded in the wall panel, the st...

[0043] The second structural form of steel tube concrete-steel braces-steel plate-wrapped concrete shear walls is as follows: Figure 4 As shown, an X-shaped steel brace 3 is set on the steel plate 2, and its upper end is connected with the steel pipe concrete frame column 1 and the upper steel beam 4 at the same time. The lower end is connected with the steel pipe concrete frame column 1 and the lower shaped steel beam 4 at the same time. Other aspects are the same as the first form.

Embodiment 3

[0045] The third structural form of steel tube concrete-steel braces-steel plate-wrapped concrete shear walls is as follows: Figure 5 Shown, be that a figure-eight shaped steel brace 3 is set on the steel plate 2, and its upper end is connected with the upper shaped steel beam 4. The lower end is connected with the steel pipe concrete frame column 1 and the lower shaped steel beam 4 at the same time. Other aspects are the same as the first form. Embodiment 4, 5, 6

[0046] When the height-to-width ratio of the shear wall is less than 1, it is better to adopt multiple composite concealed support network layout. The fourth, fifth and sixth structural forms of steel tube concrete-steel braces-steel plate-wrapped concrete shear walls are as follows: Figure 6 , Figure 7 , Figure 8 As shown, the height-to-width ratio of the shear wall is less than 1 at this time, and the steel brace in the wall panel can be selected from one of the above three methods, and the other structu...

Abstract

The invention discloses a steel pipe concrete-steel support-steel plate outer packed concrete shear wall and making method thereof, belonging to a shear wall and making method thereof. The shear wall is composed of steel pipe concrete frame columns (1) and concrete shear wall boards embedded with a steel plate (2), and is characterized in that the two ends of the shear wall are provided with steel pipe concrete frame columns (1), the frame beam is provided with a section steel beam (4), and the steel plate (2) embedded in the shear wall is provided with a steel support (3). 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 steel pipe concrete-steel brace-steel plate outsourcing concrete shear wall and a manufacturing method thereof, belonging to a shear wall and a manufacturing method thereof. Background technique [0002] my country is an earthquake-prone country. Strong earthquakes such as Haicheng and Tangshan have caused huge losses to people's lives and property. For earthquake disasters, the most fundamental measure is to do a good job in anti-seismic fortifications and improve the anti-seismic ability of engineering structures. How to enhance the seismic capacity of structures through reasonable seismic design is of great concern to engineering circles at home and abroad. One of the key components in the seismic design of structures is the shear wall, which is a major lateral force-resisting system in high-rise buildings. It has high anti-sway stiffness and high bearing capacity, but has poor ductility and is prone to brittle failure, ...
