Assembled integral reinforced concrete coupled shear wall structure with key grooves

Abstract

The invention provides an assembled integral reinforced concrete coupled shear wall structure with key grooves. The structure comprises a prefabricated shear wall with a hole and cast-in-place edge assemblies combined with the two vertical sides of the prefabricated shear wall with the hole; the prefabricated shear wall with the hole includes dark columns, intermediate wall bodies and a connectingbeam connected with the dark columns on the two sides and the intermediate wall bodies, wherein the dark columns and the intermediate wall bodies are sequentially located on the two sides of the hole; the intermediate wall bodies are connected to the cast-in-place edge assemblies, and the shear-resistant key grooves are formed in the bottoms of the intermediate wall bodies. Vertical reinforced steel bars of the prefabricated shear wall with the hole are partially broken, the number of vertical reinforced steel bar connectors and grouting sleeves is decreased, a strengthening measure that thenumber of reinforcing bars of the wall bodies and cast-in-place edge assemblies on both sides of a prefabricated wall body is increased according to the principle of equal bending strength is adopted,and the loss of the bending-resistant bearing capacity due to the breakage of the vertically distributed reinforced steel bars can be compensated for, so that the factory manufacturing costs for materials and prefabricated components are reduced; moreover, through arrangement of the shear-resistant key grooves, the decline of the shear-resistant capability at horizontal seams between layers due to the breakage of the vertical reinforced steel bars in the prefabricated shear wall with the hole can be compensated for.

Description

technical field [0001] The invention relates to an assembled integral shear wall structure, in particular to an assembled integral reinforced concrete shear wall structure with keyway combined limbs. Background technique [0002] For the "assembled integral concrete shear wall structure" that is currently emerging in China, the vertical connection of the wall reinforcement mostly adopts the "sleeve connection" or "constrained slurry anchor connection" method. These connection methods all need to connect a large number of steel bars, which not only increases the structural cost, but also causes great troubles to construction workers due to the difficulty in positioning the steel bars during installation. Contents of the invention [0003] In view of the existing or potential deficiencies in the above-mentioned prior art, the present invention provides an assembled integrated reinforced concrete shear wall structure with keyway with keyway for simplified connection, which ca...
