Laminated slab type concrete shear wall steel bar snap-fit connecting joint and construction method

Abstract

The invention discloses a laminated slab type concrete shear wall steel bar snap-fit connecting joint and a construction method. The connecting mode commonly adopts that steel bars are anchored into cast-in-situ concrete in a wall cavity, structural steel bars are forced to be disconnected, force cannot be directly transmitted, structural safety stock is lowered, the overall stiffness of a wall body is weakened, and the anti-shearing capacity of the wall body is lowered. The laminated slab type concrete shear wall steel bar snap-fit connecting joint comprises a laminated slab type concrete shear wall (1), snap-fit steel bars (5) and spring bars (6). The laminated slab type concrete shear wall is composed of two layers of concrete thin plates which form a whole through lattice steel bars (2), and the laminated slab type concrete shear wall comprises longitudinal steel bars (3) and transverse steel bars (4); and the snap-fit steel bars are set up at the short edges of the transverse steel bars, are arranged at the short edges of the transverse steel bars in advance according to the different modes and additionally provided with the spring bars according to the specific modes of the snap-fit steel bars.

Description

Technical field: [0001] The invention relates to a fastening connection node of a composite slab concrete shear wall and a construction method thereof. Background technique: [0002] At present, my country's assembly of integral reinforced concrete structures is dominated by solid walls. With the development of the industry, through the practice of a large number of projects, the advantages of hollow walls have gradually been tapped. The requirements are low, and the tower crane used in the traditional cast-in-place concrete structure can also meet the requirements; the amount of component formwork is small and the formwork material is cheap, and the amortized amount is small; the component thickness is small, the steam curing time is short, and the component strength increases quickly; compared with solid walls As far as it is concerned, the post-casting tape formwork is canceled in the true sense. Hollow walls have obvious advantages, but at this stage, the connection form ...

Problems solved by technology

Hollow walls have obvious advantages, but at this stage, the connection form of laminated slab concrete shear walls usually uses steel bars to anchor in the cast-in-situ concrete inside the cavity of the wall. Poor force effect
