Assembled integral reinforced concrete shear wall without sleeve connection and its construction method

Abstract

The invention discloses an assembled integral type reinforced concrete shear wall structure without sleeve connection and construction of the assembled integral type reinforced concrete shear wall structure without sleeve connection. The assembled integral type reinforced concrete shear wall structure comprises prefabricated wall parts, a cast-in-situ wall part, positioning screws and reinforcement structures, wherein vertical internal thread holes are formed in the tops of the prefabricated wall parts, and butt joint holes are formed in the corresponding positions at the bottoms of the prefabricated wall parts; a cast-in-situ wall part is cast and formed on the vertical two sides of the prefabricated wall part; the positioning screws are used for positioning the vertically adjacent prefabricated wall parts, wherein rod threads which are connected with the internal thread holes in a matched and screwed mode are arranged on the lower sections of the positioning screws, and rebar inserting sections which are used for bearing inserting of the butt joint holes in a matching mode are formed on the upper section of the positioning screws; and the reinforcement structures are used for fixing the rebar inserting sections in the butt joint holes. Shear wall edge members of the assembled integral type reinforced concrete shear wall structure are cast-in-situ, a middle wall is prefabricated, vertical rebars of the prefabricated wall parts are configured with the minimum reinforcement ratio, and the vertically distributed rebars are connected at the horizontal joints of an upper layerand a lower layer in a disconnecting mode, so that no sleeve is needed for connection.

Description

technical field [0001] The invention relates to an assembled integral shear wall structure, in particular to an assembled integral reinforced concrete shear wall without sleeve connection and a construction method. 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 and a construction method without sleeve connection, w...
