Ribbed grid-like reinforced concrete shear wall and making method thereof

Abstract

The invention relates to a dense-rib network steel bar concrete shearing wall and relative producing method. It uses 2-6 bricks of hollow plates with vertical chamber and transverse groove to integrate a wall along the height direction of floor; and the vertical chamber and the transverse groove individually contain vertical steel bars and transverse steel bar while they are filled by concrete to form the dense-rib network shearing wall with better anti-shearing rigidity and anti-torsion property. The invention change the single-direction dense-rib plate into new dense-rib network shearing wall with better anti-torsion rigidity and high anti-shearing rigidity, while compared to present single-direction dense-rib wall, its anti-shearing rigidity is improved 15-20 times. It can apply small high floor and high floor constructions.

Description

Technical field: [0001] The invention relates to a wall body of a building, in particular to a reinforced concrete shear wall with a dense rib grid pattern and a manufacturing method thereof, which are applied in small high-rise buildings and high-rise buildings. Background technique: [0002] At present, the one-way dense ribbed rapid wallboard in the prior art can replace traditional clay bricks, save land resources, does not need additional formwork, and is easy and quick to install. The size of the reinforcement can be increased accordingly, the construction is flexible, and the ductility of the structure is much better than that of clay brick masonry, and the advantages of better earthquake resistance have attracted widespread attention in China. This wallboard is 12m long, 3m high (one floor high), 120mm thick, with 13mm thick gypsum fiberglass sheets on both sides, and the vertical cavity of the wallboard is 94mm×250mm, filled with concrete or reinforced concrete. ...

AI Technical Summary

Problems solved by technology

[0003] However, this kind of one-way densely ribbed fast wallboard, because it uses the ring beam of each floor as the horizontal connection point, its vertical densely ribbed reinforced concrete members have only one connecting member for each floor, that is, every 3m (or greater than 3m) ) has only one connection point, and its shear stiffness is extremely poor, so it can only be used in low-rise (3-6 storey) buildings with vertical loads as the main body. In small high-rise and high-rise buildings, the main mechanical effect of wall panels is the lateral resistance The force function is the main body, while the vertical load takes a backseat. This kind of quick wall cannot be applied to small high-rise and high-rise buildings, which is its fatal weakness.
