Problems solved by technology

The reinforced concrete shear wall of this conventional structure can meet certain shear resistance requirements, but with the continuous increase of high-rise buildings, the height of the reinforced concrete shear wall increases, and the seismic performance of the reinforced concrete shear wall is raised. higher requirements, but the concrete periphery in the prior art lacks protection, and the concrete shear wall still has the problem of high brittleness, and its earthquake resistance is insufficient

Embodiment Construction

[0021] An example of a reinforced concrete shear wall Figure 1~3 As shown, the reinforced concrete shear wall includes two first columns 7, a second column 8 arranged at intervals from left to right and a wall between the two columns. The first column 7 and the second column 8 include The metal column 1 extending in the direction, the metal column 1 is a square steel pipe structure made of Q390 material, the adjacent sides of the first column 7 and the second column 8 are arranged in parallel, and the metal column concrete 2 is poured in the center hole of the metal column, The metal column concrete is high-strength concrete of C60~C100. The wall includes a metal skeleton, and the metal skeleton includes double rows of horizontal steel bars 4 and double rows of vertical steel bars 3. The horizontal steel bars and vertical steel bars are HRB500 steel bars, and the left end of the metal frame is connected to the first column through a shear connection key 5 On the right side o...

Abstract

The invention relates to a reinforced concrete shear wall, which comprises at least two vertical columns arranged at intervals and a wall body arranged between corresponding two adjacent vertical columns, the vertical columns include metal columns extending in the vertical direction, and the wall body includes wall concrete The layer is fixedly connected to the metal frame between two corresponding adjacent metal columns, and the wall concrete layer is poured into an integral structure with the metal frame and the opposite sides of the corresponding two adjacent metal columns.

Description

technical field [0001] The invention relates to reinforced concrete shear walls in the construction field. Background technique [0002] Concrete shear walls are common lateral force-resisting components in high-rise buildings. The rationally designed reinforced concrete shear walls have the characteristics of high bearing capacity, high lateral stiffness, good ductility and strong energy dissipation capacity. Existing reinforced concrete shear walls such as public number is CN106760611A, the application name is the reinforced concrete shear wall disclosed in "reinforced concrete shear wall and construction method thereof for improving shear wall structural deformation capacity", the reinforced concrete shear wall The wall includes a double-layer reinforced mesh sheet composed of horizontally distributed steel bars and longitudinally distributed steel bars, and concrete is poured on the double-layer reinforced mesh sheet to form a reinforced concrete shear wall. The reinfor...
