Junction structure of bare concrete shear wall and inner filler wall and implementation method thereof

Abstract

The invention discloses a junction structure of a bare concrete shear wall and an inner filler wall. The structure comprises the dry concrete shear wall and the inner filler wall, wherein the two sides of the junction where shear wall is vertically or horizontally connected with the inner filler wall are sunk inwards to form bar-shaped concave surfaces; the concave surfaces are conglutinated to the inner filler wall through an alkali-resistant glass fiber gridding fabric and plain grout; the base layer of the inner filler wall is plastered; the surface layer is plastered by grout; after the surface layers of the parts, positioned on the concave surfaces, of the shear wall are plastered by the grout, the surfaces of the other parts are on the same horizontal surface. The structure has the advantages that after the structure is adopted, plastering on the place where the shear wall and the inner filler wall are connected is not easy to crack; due to the fact that the shear wall has a bare concrete effect, plastering is not required, materials are saved, construction pollution is reduced, and repairing cost is also saved; meanwhile, the flatness and observation quality of the surface of a wall body are better.

Description

technical field [0001] The invention relates to a building structure, in particular to the junction structure of a clear-faced concrete shear wall and an inner filling wall and an implementation method thereof. Background technique [0002] For buildings with frame shear wall structure, if the shear wall achieves the effect of fair-faced concrete, the plastering can be canceled, which can save materials, reduce construction pollution, and avoid disputes caused by common problems of plastering quality. This saves on rework costs. However, the inner filling wall needs to be plastered. In order to prevent the cracking of the plastering at the junction of different bases (concrete shear wall and filling wall) due to the different deformation coefficients of the base material of the wall, the usual practice is to use two bases at the junction. Paste the tension mesh on the surface, such as alkali-resistant fiber mesh cloth, metal mesh, etc., and then plaster the surface to cover...

Problems solved by technology

However, the inner filling wall needs to be plastered. In order to prevent the cracking of the plastering at the junction of different bases (concrete shear wall and filling wall) due to the different deformation coefficients of the base material of the wall, the usual practice is to use two bases at the junction. Paste the tension mesh on the surface, such as alkali-resistant fiber mesh cloth, metal mesh, etc., and then plaster the surface to cover the tension mesh. This method creates a problem. Paste the tension mesh and its surface plastering layer After completion, the paste area will protrude from the fair-faced concrete shear surface, which will affect the flatness of the fair-faced concrete shear wall surface

In order to eliminate this effect, the current practice is to expand the plastering width on the surface of the mesh, so that the overall error of the pasted area protruding from the concrete surface is weakened, but this treatment method will affect the quality of the surface of the fair-faced concrete.
