T-shaped assembly type node connecting structure of double steel plate-concrete composite shear wall

Abstract

A T-shaped assembly type joint connecting structure of a double-steel-plate-concrete composite shear wall comprises the prefabricated assembly type shear wall, a concrete structure layer, T-shaped steel connecting pieces, embedded steel plates, sleeves, prestressed tendons, horizontal connecting tendons and the like. The prefabricated assembly type shear wall comprises two steel plates which are oppositely arranged, and the two steel plates are filled with concrete. The penetrating fabricated shear wall is provided with horizontal connecting ribs, two annular blocking rings are arranged at the positions, corresponding to the steel plates on the two sides, of each horizontal connecting rib, the position between the two steel plates is filled with a concrete interlayer, and prestressed steel bars are preset in the shear wall so that the shear capacity of the shear wall can be improved. The node T-shaped steel and the prefabricated shear wall are manufactured into a whole in an assembly type factory and welded to a pre-buried steel plate in an electric welding mode. And after the T-shaped steel is welded stably, grouting materials are preset in the prefabricated grouting hole channels. Sleeves are vertically welded outside the two steel plates and are bonded and reinforced through epoxy resin glue, and the sleeves and the rectangular beams are connected through high-strength bolts and expansive cement.

Description

technical field [0001] The invention relates to the field of prefabricated node connection structures, in particular to a T-shaped prefabricated node connection structure of a double steel plate-concrete composite shear wall. Background technique [0002] With the continuous acceleration of urbanization in our country, the construction industry has also been continuously improved. In order to meet the needs of housing, the construction industry continues to expand its scale, enhance its technology and improve its construction quality. Prefabricated buildings are favored by the construction industry due to their low cost, energy saving, environmental protection, and high efficiency. With the continuous expansion of demand in the construction industry, the requirements for prefabricated structural nodes are also getting higher and higher.
