[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a relatively lightweight mullite brick, comprising a mullite brick body 1. Multiple through holes 101 are provided at the top and bottom of the interior of the mullite brick body 1. The number of through holes 101 at the top and bottom of the interior of the mullite brick body 1 are the same and correspond one-to-one. An inner cavity 102 is provided inside the mullite brick body 1, and both the through holes 101 at the top and bottom of the interior of the mullite brick body 1 communicate with the inner cavity 102.

[0024] In use, multiple corresponding through holes 101 are set inside the upper and lower parts of the mullite brick body 1, forming an inner cavity 102 that communicates with these through holes. This effectively reduces the overall weight, thereby greatly improving the convenience of transporting the mullite brick. Furthermore, the structural design of the through holes 101 and the inner cavity 102 enhances the sound insulation performance of the mullite brick body 1, reduces the propagation of sound waves, solves many inconveniences caused by the weight of traditional mullite bricks, and significantly improves its portability and practicality.

[0025] Please see Figure 3 and Figure 4 The inner cavity 102 is provided with a steel pipe 2, and there are multiple steel pipes 2. The number of steel pipes 2 and the through holes 101 are the same and their positions are corresponding. The upper end and the lower end of the steel pipe 2 extend into the through holes 101 above the mullite brick body 1 and below the mullite brick body 1, respectively.

[0026] By setting the steel pipe 2 in the inner cavity 102, the structural strength of the mullite brick can be further enhanced, and its compressive and bending resistance can be improved. At the same time, the steel pipe 2 can also serve as a support or connection structure for other functional components, making multifunctional applications of mullite brick possible and increasing its practicality.

[0027] Please see Figure 3 and Figure 4 Steel pipe 2 is a hollow steel pipe, and steel pipe 2 is made of lightweight stainless steel.

[0028] Hollow steel pipes made of lightweight stainless steel not only ensure sufficient structural strength but also further reduce the overall weight of mullite bricks, improving their portability. Stainless steel also has good corrosion resistance, which can extend the service life of mullite bricks. At the same time, the hollow steel pipe design also helps to reduce material consumption and lower production costs.

[0029] Please see Figure 1 Connecting protrusions 3 are symmetrically arranged at the front and rear ends of the upper part of the mullite brick body 1. The mullite brick body 1 and the connecting protrusions 3 are integrated into one structure. Connecting grooves 103 are symmetrically arranged at the front and rear ends of the lower part of the mullite brick body 1.

[0030] By setting the connecting protrusion 3 and the connecting groove 103, the connection and assembly between mullite bricks can be easily realized, which improves construction efficiency. At the same time, this connection method also has a certain degree of stability and reliability, which can ensure the safety of mullite bricks during use.

[0031] Please see Figure 1 The mullite brick body 1 has symmetrically arranged side grooves 104 on the middle of both sides.

[0032] By setting side grooves 104 on both sides of the mullite brick, the irregularity of the side of the mullite brick can be increased, the connection between the side of the mullite brick and the mortar can be improved, and the design of the side grooves can also increase the aesthetics of the mullite brick.

[0033] Please see Figure 1 and Figure 2 On one side of the mullite brick body 1, the front and rear ends are symmetrically fixed with inserts 4, which are made of lightweight stainless steel pipes. On the other side of the mullite brick body 1, the front and rear ends are symmetrically provided with slots 105. The number of inserts 4 and slots 105 are the same and their positions correspond. The slots 105 are set as cylindrical grooves, and the length of the inserts 4 is less than the depth of the slots 105.

[0034] The design of the insert post 4 and the slot 105 makes it easy to connect and fix mullite bricks. This connection method is not only simple and quick, but also has a certain degree of stability and reliability.

[0035] Please see Figure 4 The mullite brick body 1 has symmetrical functional cavities on both sides inside. The functional cavities are respectively equipped with a heat insulation layer 5 and a sound absorption layer 6. The heat insulation layer 5 is made of aluminum silicate fiber material, and the sound absorption layer 6 is made of porous ceramic material.

[0036] By setting the heat insulation layer 5, the heat transfer and loss inside the mullite brick can be further reduced. The aluminum silicate fiber material has good heat insulation performance, which can ensure the stability and safety of the mullite brick in high-temperature environments. By setting the sound absorption layer 6, the propagation and reflection of sound waves inside the mullite brick can be effectively reduced. The porous ceramic material has a rich microporous structure, which can effectively absorb sound waves and reduce noise levels, thus improving the overall performance of the mullite brick.

[0037] Working principle: During use, the multiple corresponding through holes 101 set at the top and bottom of the mullite brick body 1, and the inner cavity 102 connected by these through holes, not only effectively reduce the overall weight and improve the convenience of transportation, but also enhance the sound insulation performance and reduce the propagation of sound waves through its structural design. In addition, the lightweight stainless steel hollow steel pipe set in the inner cavity 102 enhances the structural strength of the mullite brick and improves its compressive and bending resistance. At the same time, the setting of connecting convex strips 3 and connecting grooves 103, as well as the design of inserts 4 and slots 105, make the connection and assembly between mullite bricks simple and quick, and have a certain degree of stability and reliability. In addition, the side grooves 104 set on both sides of the mullite brick increase the connectivity with mortar. By setting a heat insulation layer made of aluminum silicate fiber material and a sound absorption layer made of porous ceramic material in the functional cavity inside the mullite brick, heat transfer and loss can be further reduced and sound insulation can be increased, thus improving the overall performance of the mullite brick.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
