Steel plate prefabricated concrete double-plate shear wall

Abstract

The invention discloses a steel plate prefabricated concrete double-plate shear wall. The steel plate prefabricated concrete double-plate shear wall comprises a steel plate, anti-sliding keys, profile steel, prefabricated concrete wall pieces, a cavity and a truss steel rib, wherein the steel plate is placed in the center between the two prefabricated concrete wall pieces, four edges of the steel plate are respectively welded with inner end-post profile steel and an inner steel plate or the profile steel, the anti-sliding keys are arranged on the steel plate, the prefabricated concrete wall pieces and the steel plate are connected into a whole through the truss steel rib and the anti-sliding keys, and concrete is poured into the cavity in the shear wall and the profile steel. The steel plate prefabricated concrete double-plate shear wall is simple in structure, solves the problem that an upper-layer wall body is insufficiently connected with a lower-layer wall body, and strengthens the overall performance of the combining portions of the wall bodies.

Description

technical field [0001] The invention belongs to the field of building structures and relates to a steel plate prefabricated concrete double-slab shear wall. Background technique [0002] As my country's construction industrialization process continues to advance, the country vigorously advocates prefabricated buildings. The precast concrete double-slab shear wall is a new structural form imported from Germany. It has been used in Germany for nearly 20 years and has met the requirements of standardized design, industrial production and assembly construction. Germany is a low-earthquake country and the structure did not take into account the seismic requirements. However, earthquakes occur frequently in my country, so the structure must be improved before it can be widely promoted in China. [0003] The following problems mainly exist in the application of precast concrete double-slab shear walls: 1. After the hoisting is completed, when the cavity concrete is poured, especi...

AI Technical Summary

Problems solved by technology

[0003] The following problems mainly exist in the application of precast concrete double-slab shear walls: 1. After the hoisting is completed, when the cavity concrete is poured, especially when self-compacting concrete is used, the precast wall panels on both sides will have cracks due to insufficient connection, or even be biased. 2. There is not enough connection between the upper and lower walls, which is prone to large lateral displacement; 3. The overall performance of the superimposed surface of the double-slab shear wall is weaker than that of the all-cast-in-place shear wall; 4. The construction of the edge components is complicated, which prolongs the construction period

[0004] Due to the existence of many of the above problems, the promotion and application of the precast concrete double-slab shear wall structure in China has been hindered.
