Anti-cracking structure for joint of full-concrete outer wall under-window filling wall and shear wall and construction method thereof

Abstract

The invention belongs to the technical field of concrete outer wall construction, and provides an anti-cracking structure for a joint of a full-concrete outer wall under-window filling wall and a shear wall and a construction method thereof in order to prevent the problem that cracks are generated at the positions such as the under-window wall due to concrete shrinkage. Anti-cracking steel bars and joint pulling plates are arranged in a concrete pouring layer at intervals, wherein the joint pulling plates comprise horizontal structure joint pulling plates and vertical structure joint pulling plates; the horizontal structure joint pulling plates are arranged between floors or beams of all layers and the under-window filling wall; and the vertical structure joint pulling plates are arrangedbetween the shear wall and the under-window filling wall; transverse anti-cracking steel bars are arranged at the joint of the shear wall and the under-window filling wall, and the transverse anti-cracking steel bars penetrate through the vertical structure joint pulling plates to be bound and overlapped with wall body steel bars of the shear wall and the under-window filling wall on the two sides. The anti-cracking structure is convenient to assemble and disassemble, construction joints are avoided, the hidden danger of water leakage of the structure is reduced, and the applicability is improved. The operation is convenient, the construction quality and effect are good, the change of the overall rigidity is avoided, the construction period is shortened, and the structural safety is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of concrete exterior wall construction, and specifically relates to an anti-cracking structure at the joint between a filling wall and a shear wall under a full concrete exterior wall window and a construction method thereof. Background technique [0002] When the aluminum alloy formwork support system is used in the construction of the concrete main structure, the aluminum alloy formwork has the characteristics of large rigidity and strong plasticity. During the construction process, the external wall opening masonry infill wall structure is taken out of the concrete structure at one time, but this may be Cracks occurred in the walls and other places under the windows due to the shrinkage of the concrete. [0003] The application number is 201910837911.2, and the name of the invention is: Integrated construction process of FS thermal insulation external formwork, aluminum alloy formwork and climbing frame. In this...
