The problem that the plastering of the concrete porous brick wall is easy to peel off from the wall can be greatly improved, and the problem that the plastering of the wall is easy to crack can be alleviated to a certain extent. The utility model is suitable for the improvement of concrete porous bricks and various concrete hollow small blocks, and has strong versatility.

Description

A concrete porous brick for preventing plaster peeling

technical field

The utility model relates to building materials, in particular to a concrete porous brick which prevents plastering from peeling off.

Background technique

At present, the plastering of the known concrete porous brick exterior wall and interior wall is easy to fall off, the main reason is that the concrete porous brick has poor water absorption and poor bonding with cement mortar. The treatment method is mainly to fix galvanized steel wire mesh on the base side of the wall. This method alleviates the problem of easy peeling between the plaster and the base layer of the wall to a certain extent, but with the corrosion of the galvanized steel wire mesh and the loosening of the fixing parts with the base layer of the wall, part of the plaster will still peel off from the base layer of the wall, which is durable. Poor sex.

Utility model content

In order to overcome the disadvantage that the existing concrete porous brick wall is easy to be glazed when plastered, the purpose of the utility model is to provide a concrete porous brick which prevents the plaster from peeling off.

The purpose of the utility model is achieved through the following approaches: a concrete porous brick that prevents plastering from peeling off, which includes a brick body, and a plurality of grooves are distributed on the side wall of the brick body.

As a further optimization of the solution, the groove is quadrangular or circular.

As a further optimization of the solution, the distance between the grooves is 30-50mm.

As a further optimization of the solution, the depth of the groove is 5 mm.

As a further optimization of the solution, the brick body is provided with through holes.

Compared with the prior art, the utility model has the beneficial effects of a concrete porous brick that prevents plastering from peeling off: the utility model is suitable for the improvement of concrete porous bricks and various concrete hollow small blocks, and has strong versatility. It effectively improves the bonding performance between the concrete porous brick wall and the plaster, and improves the integrity of the masonry wall. The problem that the plastering of the concrete porous brick wall is easy to peel off from the wall can be greatly improved, and the problem that the plastering of the wall is easy to crack can be alleviated to a certain extent.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model;

In the figure, a brick body 1, a side wall 2, a groove 3, and a through hole 4.

Detailed ways

As shown in Figure 1, the utility model is a concrete porous brick that prevents plastering from peeling off. It includes a brick body 1, a through hole 4 is arranged on the brick body 1, and several grooves 3 are distributed on the side wall 2 of the brick body 1. , the grooves 3 are quadrilateral or circular, the distance between the grooves 3 is 30-50mm, and the depth of the grooves 3 is 5mm.

When in use, the exterior wall plaster is squeezed into the groove of the concrete porous brick, so that the exterior wall plaster is concave-convex toward the side of the wall, and the grooves on the brick connecting surface strengthen the connection between the masonry mortar and the brick.
