Prefabricated stiff concrete shear wall panel with U-shaped anchor steel plate, fabricated stiff concrete shear wall and manufacturing method

Abstract

The invention provides a prefabricated rigid concrete shear wall panel with a U-shaped anchor steel plate, an assembled prefabricated rigid concrete shear wall and a manufacturing method. The shear wall panel includes an edge restraint member, a grouting sleeve, and an embedded connection concrete , U-shaped anchoring steel plate, built-in bolts, wherein, the edge constraining member includes edge shaped steel and edge stressed longitudinal bars built in both sides of the wall and along the longitudinal direction of the wall, and the upper or lower ends of the edge stressed longitudinal bars are fixed with Grouting sleeve; in the middle of the top and bottom of the wall, there is embedded connecting concrete protruding from the wall concrete, the embedded connecting concrete is covered with U-shaped anchor steel plates, and built-in bolts are pre-embedded in the embedded connecting concrete. The prefabricated stiffened concrete shear wall panel with U-shaped anchor steel plate provided by the present invention has high lateral rigidity, high bearing capacity, clear force of the connection structure between the walls, reliable connection, convenient operation, low cost, and universal use Strong, may be used in high-rise or super high-rise prefabricated buildings.

Description

technical field [0001] The present invention generally relates to the field of building structure engineering, and mainly relates to a prefabricated stiffened concrete shear wall panel with a U-shaped anchor steel plate, a prefabricated stiffened concrete shear wall and a manufacturing method thereof, and can be specifically applied to assembled stiffened concrete in structure. Background technique [0002] At present, prefabricated buildings have become the main direction of the transformation of the construction industry. The prefabricated shear wall structure is the main structural form used in high-rise prefabricated buildings. However, due to the lack of relevant research, the height of the prefabricated shear wall structure is limited, which seriously restricts the application of prefabricated buildings in high-rise and super high-rise buildings. The prefabricated stiff concrete technology is to build steel and other components into the reinforced concrete shear wall...

Problems solved by technology

Most of the "dry" connections require relatively complicated construction techniques and high construction accuracy, and the force transmission path is not clear, the theoretical research is insufficient, and the structural integrity is poor.

The "wet" connection mostly uses post-cast belt connection, which has the advantages of good integrity and similar mechanical performance indicators to cast-in-place structures, but there are also complex construction operations, high construction costs, and poor adaptability to components under different stress conditions. lack of
