Vertical mixed connection structure and method of prefabricated internal wallboards for assembling shear wall structure

Abstract

The invention discloses a vertical mixed connection structure and method of prefabricated internal wallboards for assembling a shear wall structure. On the structure, edge components of upper-layer and lower-layer prefabricated internal wallboard structures are overlapped through vertical steel bars and U-shaped ribs, and horizontal reinforcing ribs and local cast-in-place concrete are arranged in a closed ring so as to realize the edge components equivalent to the cast-in-place concrete, the vertically distributed steel bars at the middle part of the components are connected in a manner of indirect overlapping by use of mortar anchor steel bars of a retention metal mortar anchor pipe so as to form an entire shear wall. By utilizing the local cast-in-place concrete moist joint at the edgecomponent part formed by the mixed connection and the dry joint of bedding and grouting at the part of the vertically distributed steel bars, the shear strength and rigidity of the horizontal jointing part of the prefabricated internal wallboards are improved; casting holes reserved at the bottom of the edge components can be used for solving the problem of casting the local cast-in-place concrete; and the vertically distributed steel bars are connected in a manner of indirect overlapping by use of the mortar anchor, which facilitates the installation and temporary fixation of the wallboards on a concrete floor. The mixed connection structure of the prefabricated internal wallboards, provided by the invention, ensures the overall performance of the shear wall; and construction is convenient.

Description

technical field [0001] The invention relates to a vertical mixed connection technology for on-site assembly of prefabricated inner wall panels of a building assembly shear wall structure, and belongs to the technical field of assembly concrete structures in construction engineering. Background technique [0002] The shear wall component is the main force-bearing component of the shear wall structure of high-rise buildings, and it is also the primary anti-seismic energy-dissipating component. The overall performance and seismic performance of prefabricated concrete shear wall structures depend on the strength, stiffness and ductility of prefabricated shear wall components. The layered prefabrication of prefabricated shear wall components, the vertical connection structure and performance at the horizontal joints directly determine the integrity, bearing capacity and deformation capacity of the shear wall components and their overall structure.
