Description

Hollow brick

technical field

The utility model relates to the field of building materials, in particular to a hollow brick which has thermal insulation and sound insulation properties and is convenient for fixing with expansion bolts.

Background technique

Existing hollow bricks are usually sintered in one piece. The front and rear side walls are solid walls, and there are multiple cavities distributed inside. When the expansion bolt is fixed in the hole, because the wall is too thin, the expansion flap of the expansion bolt cannot be limited, so the expansion bolt cannot be fixed. If the front and rear side walls are too thick, on the one hand, more materials will be used, and the cost will increase. The thermal insulation and sound insulation performance of the walls are poor, therefore, the existing hollow bricks need to be improved. In addition, the side walls of the existing hollow bricks are all flat. When the hollow bricks are used, the hollow bricks need to be built into walls with mortar or lime mortar. The contact area between building materials such as mortar or lime mortar and the hollow bricks is flat, and the adhesion is small. Therefore, the wall The firmness is poor.

Contents of the invention

The purpose of this utility model is to provide a hollow brick that can solve the aforementioned problems in view of the existing problems of the existing hollow bricks pointed out in the background technology.

The technical scheme that realizes the purpose of the invention of the utility model is as follows:

A hollow brick, which includes a brick body formed by sintering. Several rectangular cavities are arranged in the middle of the brick body, and the parts of the brick body near the front side wall and the rear side wall are respectively provided with cavities with cross-sections in the shape of a square. Several vertical stucco grooves for filling hollow brick building materials are distributed on the outer surface of the body.

In order to facilitate full contact between building materials and the stucco groove and increase the firmness of the wall, the stucco groove is trapezoidal groove, square groove or arc groove.

In order to utilize waste and reduce the cost of hollow bricks, the brick body is a brick body formed by sintering clay, slag, coal gangue and coal ash.

The advantage of the hollow brick of the present invention is that the hollow brick of the present utility model has a simple structure, and a cavity with a cross-section of a square shape is respectively arranged in the hollow brick near the front side wall and the rear side wall, and the transverse direction of the inside of the square-shaped cavity is The wall and the longitudinal wall support the front side wall and the rear side wall, strengthen the structure of the front side wall and the rear side wall, and at the same time, this structure saves more materials. When the expansion bolt is to be installed on the wall, the longitudinal wall can form a limit to the expansion flap of the expansion bolt, so that the expansion bolt is firmly fixed on the wall. When the steel nail is fixed, the longitudinal wall can also increase the adhesion to the steel nail, so that the steel nail can be fixed more firmly. At the same time, because of the Tian-shaped cavity, the wall has good sound insulation and heat preservation. Because several vertical stucco grooves are set on the outer side walls of the hollow bricks, when building walls, mortar or lime grout fills the stucco grooves and the gaps between the hollow bricks, so that after the mortar or lime grout solidifies, it will form The zigzag filling layer increases the firmness of the hollow brick connection.

Description of drawings

Fig. 1 is a schematic cross-sectional view of a hollow brick of the present utility model;

In the figure, 1 is a brick body, 2 is a cavity, 3 is a front side wall, 4 is a rear side wall, 5 is a painting groove, 6 is a transverse wall, and 7 is a longitudinal wall.

Detailed ways

Referring to a hollow brick shown in Figure 1, it includes a sintered brick body 1, several rectangular cavities 2 are arranged in the middle of the brick body 1, and the inside of the brick body 1 is close to the front side wall 3 and the rear side wall 4. The parts are respectively provided with cavities with cross-sections in the shape of a square, and several vertical stucco grooves 5 for filling hollow brick building materials are distributed on the outer surface of the brick body 1 .

In order to facilitate sufficient contact between building materials and the stucco groove and increase the firmness of the wall, the stucco groove 5 is a trapezoidal groove, a square groove or an arc groove.

In order to utilize waste and reduce the cost of hollow bricks, the brick body is a brick body formed by sintering clay, slag, coal gangue and coal ash.

When the hollow brick of the present invention is in use, the front side wall 3 of the hollow brick is facing indoors, and the rear side wall 4 is facing outdoors, and building materials such as mortar or lime slurry are used to build walls. This kind of hollow brick is very convenient to use, and the manufacturing cost is low. The transverse wall 6 and the longitudinal wall 7 support the front side wall 3 and the rear side wall 4, strengthen the structure of the front side wall 3 and the rear side wall 4, and at the same time, this structure saves more materials. When the expansion bolt is to be installed on the wall, the longitudinal wall 7 can form a limit to the expansion flap of the expansion bolt, so that the expansion bolt is firmly fixed on the wall. At the same time, because of the Tian-shaped cavity, the wall has good sound insulation and heat preservation. Because several vertical painting grooves are set on the outer side wall of the hollow brick, when building the wall, mortar or lime slurry fills the gap between the painting groove 5 and the hollow brick, and after the mortar or lime slurry solidifies, it will A sawtooth-shaped filling layer is formed, which increases the firmness of the hollow brick connection.

The above embodiments are descriptions of specific implementations of the present utility model, rather than limitations of the present utility model. Those skilled in the art can also make various transformations and changes without departing from the spirit and scope of the present utility model. Changes to obtain corresponding equivalent technical solutions, so all equivalent technical solutions should be included in the patent protection scope of the present utility model.
