Description

Technical Field

[0001] This utility model belongs to the field of pressure-resistant brick technology, specifically relating to a pressure-resistant brick. Background Technology

[0002] Existing pressure-resistant bricks, as a type of extruded floor tile, are widely used in public places with high traffic such as squares, stations, and sidewalks due to their high compressive strength. Typically, to achieve high strength, pressure-resistant bricks are over 30mm thick. This thickness results in poor plasticity, making molding difficult and leading to high drying and sintering shrinkage rates. Consequently, the brick blanks are prone to drying cracks, and the sintered finished products are also susceptible to fine and hidden cracks, resulting in a high rate of wastage. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a pressure-resistant brick.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a pressure-resistant brick, including a brick body, two through grooves are longitudinally opened at the center of the brick body, the two through grooves form a main support plate at the middle position inside the brick body, the main support plate is located at the middle position of the brick body, and two inclined bracing plates are provided in each of the two through grooves, the two inclined bracing plates are symmetrically arranged in the two through grooves.

[0005] Preferably, the main support plate is vertically arranged, and both through slots are rectangular structures of the same size. The two diagonal braces are of the same thickness, and their tops are connected to each other at the middle position of the upper surface of the through slot.

[0006] Preferably, the bottoms of the two inclined bracing plates are respectively connected to the two sides of the bottom of the through groove, and the two inclined bracing plates are integral with the brick body.

[0007] Preferably, the thickness of the main support plate is greater than the thickness of the two diagonal bracing plates.

[0008] Preferably, the top of the brick has multiple sets of permeable holes arranged longitudinally, and the permeable holes are connected to the through groove.

[0009] The beneficial effects of this utility model are as follows: By setting through grooves inside the brick body, the air flow inside the brick body can be increased, ensuring the consistency of the internal and external shrinkage rates during the drying and sintering process of the brick body, thereby avoiding cracks in the brick blank and preventing a reduction in the pressure resistance of the brick body; during the extrusion molding process of the brick body, a main support plate and a diagonal brace plate are formed, which can play a role in supporting the internal structure of the brick body. When the brick body is under pressure, the diagonal brace plate and the main support plate can transfer the force to the bottom of the brick body, thereby preventing the brick body from cracking.

[0012] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0013] Example: A pressure-resistant brick, such as Figure 1 As shown, the device includes a brick body 1. Two through slots 2 are longitudinally formed at the center of the brick body 1. The two through slots 2 form a main support plate 3 at the middle position inside the brick body 1. The main support plate 3 is located at the middle position of the brick body 1. Two diagonal bracing plates 4 are provided in each of the two through slots 2. The two diagonal bracing plates 4 are symmetrically arranged in the two through slots 2. The main support plate 3 is vertically arranged. Both through slots 2 are rectangular structures of the same size. The two diagonal bracing plates 4 have the same thickness. The tops of the two are connected to each other and are connected to the middle position of the upper surface of the through slot 2.

[0014] The bottoms of the two inclined bracing plates 4 are respectively connected to the two sides of the bottom of the through groove 2, and the two inclined bracing plates 4 and the brick body 1 are integral structures.

[0015] The thickness of the main support plate 3 is greater than the thickness of the two diagonal bracing plates 4; the top of the brick body 1 has multiple sets of permeable holes 5 longitudinally opened, and the permeable holes 5 are connected to the through groove 2. In order to increase the pressure resistance of the brick body 1, the aggregate used will be smaller. When the brick body 1 is bonded by adhesive, the permeability of the brick body 1 will be reduced. The setting of permeable holes 5 can increase the permeability of the pressure-resistant brick.

[0016] The principle of this utility model is as follows: During the extrusion molding process, the brick body 1 directly forms a through groove 2, a main support plate 3, and an inclined support plate 4 through a mold. The through groove 2 is divided into multiple through cavities by two inclined support plates 4. The through cavity setting can increase the air flow inside the brick body 1, ensuring the consistency of the internal and external shrinkage rates during the drying and sintering process of the brick body 1, thereby avoiding cracks in the brick blank and preventing a reduction in the pressure resistance of the brick body 1. During the extrusion molding process, the main support plate 3 and the inclined support plate 4 are formed. The setting of the two can play the role of internal support for the brick body 1. When the brick body 1 is under pressure, the inclined support plate 4 and the main support plate 3 can transfer the force to the bottom of the brick body 1, thereby preventing the brick body 1 from cracking.

[0017] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
