Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a porous brick that prevents deformation and cracking. Background Art

[0002] Bricks are small blocks used for stacking and building walls in construction. They are made from mud through processing, molding, and drying. Porous bricks are bricks with many holes on them. The walls made have cavities inside, which can achieve the effect of thermal insulation and sound insulation, making the indoor environment more comfortable.

[0003] The material between the holes of the existing porous bricks is relatively thin. During the sintering process, the drastic temperature change is likely to cause cracks at the edges of the holes, affecting the strength of the bricks. After being built on the wall, the humidity on the surface of the porous bricks is different from that inside, which is also prone to cracks, affecting the bearing strength of the wall. Therefore, a porous brick that resists deformation and cracking is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a porous brick that prevents deformation and cracking. Expansion joints are arranged on the brick body to divide the brick body and the holes. The deformation of various parts on the brick body is more uniform, thereby preventing the brick body from cracking, which is beneficial to improving the practicality of the porous brick.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a porous brick that prevents deformation and cracking, including a brick body, a plurality of evenly distributed holes are opened on the brick body through its thickness direction, and a plurality of evenly distributed first expansion grooves and second expansion grooves are opened on the surface of the brick body, the first expansion grooves and the second expansion grooves are staggered and perpendicular to each other, and the connection between the first expansion groove and the second expansion groove is located at the axis of the hole.

[0006] Preferably, a plurality of equally spaced telescopic annular grooves are coaxially opened in the hole along its length direction.

[0007] Preferably, a third telescopic groove and a fourth telescopic groove are provided at the connection points of adjacent telescopic ring grooves, and the third telescopic groove is connected to the first telescopic groove at one end close to the surface of the brick body, and the fourth telescopic groove is connected to the second telescopic groove at one end close to the surface of the brick body.

[0008] Preferably, the four sides of the brick body are provided with evenly distributed anti-slip grooves along the width direction thereof.

[0009] Preferably, the first telescopic groove and the second telescopic groove are both located in the middle of the adjacent anti-slip groove.

[0010] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0011] 1. By arranging the first expansion groove and the second expansion groove on the surfaces of the brick body at both ends of the hole, and the intersection of the first expansion groove and the second expansion groove is located at the axis of the hole, the surface of the brick body can be evenly divided, so that when the surface of the brick body expands and contracts due to heat, the deformation of each part is close, reducing the occurrence of cracks, which is beneficial to improving the practicality of the brick.

[0012] 2. By setting the expansion ring groove in the hole, the hole is divided in the length direction, so that the brick body and the hole can better cope with the deformation caused by the temperature difference between the inside and the outside, further reduce the occurrence of cracks, and help improve the practicality of the brick.
