Description

Technical Field

[0001] This utility model relates to the field of refractory brick technology, and more specifically, to a tenon-and-mortise type self-locking refractory brick. Background Technology

[0002] With the development of industrial technology, mortise and tenon joints have been gradually applied to the field of refractory bricks to replace traditional mortar masonry methods, aiming to achieve rapid installation and stable connection of refractory bricks. Existing refractory bricks using mortise and tenon joints often have relatively simple tenon and mortise designs, mostly rectangular structures. In practical use, this simple mortise and tenon structure has many problems. On the one hand, when the rectangular tenon and mortise are joined, they rely solely on side contact for positioning, resulting in insufficient tightness. During the operation of thermal equipment, factors such as thermal expansion and contraction due to high temperatures and equipment vibration can easily cause the refractory bricks to loosen and misalign, leading to a decrease in overall structural stability. On the other hand, the installation process of existing mortise and tenon structure refractory bricks requires workers to repeatedly adjust the position of the tenon and mortise to ensure alignment, resulting in low installation efficiency and difficulty in meeting the needs of large-scale, rapid construction.

[0003] To address the problems in the aforementioned related technologies, this utility model proposes a tenon-and-mortise type self-locking refractory brick. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art above, thereby providing a tenon-and-mortise type self-locking refractory brick;

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tenon-and-mortise type self-locking refractory brick, comprising a main body, the main body being rectangular in shape, a protrusion being provided on the upper surface of the main body, the length of the protrusion being the same as the length of the main body, the remaining width of the upper surface of the main body being only half the width of the protrusion, the protrusion and the main body being fixedly arranged, and a T-shaped groove being provided inside the left side of the main body.

[0006] Preferably, a T-shaped groove is also provided on the left side of the protrusion, and round holes are provided on the left and right sides of the main body. The round holes are arranged linearly at equal intervals, and there are a total of six round holes.

[0007] Preferably, a bottom groove is provided below the main body, the bottom groove extends upward, and the width of the bottom groove is the same as the width of the protrusion.

[0008] Preferably, a T-shaped block is provided on the right side of the main body, and the T-shaped block is fixedly provided on the right side of the main body. The T-shaped block and the T-shaped groove have the same shape.

[0009] Preferably, the length of the T-shaped block is the same as the length from the bottom groove to the upper surface of the protrusion. A bottom block is fixedly installed inside the bottom groove and extends downward. A top groove is provided above the protrusion. The top groove and the bottom block have the same shape, and the bottom block can be inserted into the bottom groove. Beneficial effects

[0010] The main body is fixed front and back by the cooperation between the T-shaped blocks and T-shaped grooves. The stacking from top to bottom makes it easier to assemble. The round holes effectively reduce the heat conduction rate, improve the overall heat preservation effect, reduce heat loss, improve energy utilization efficiency, reduce cracks or breaks caused by drastic temperature changes, such as alternating hot and cold, extend the service life of refractory bricks, and reduce maintenance frequency.

[0011] By designing a matching bottom groove and bottom block, the left-right swaying caused by the main body connection is reduced, as is the force borne by the T-groove connection, preventing the T-groove from breaking and extending the service life of the refractory bricks.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5 In this embodiment of the utility model, a tenon-and-mortise type self-locking refractory brick includes a main body 1. The main body 1 is rectangular. A protrusion 11 is provided on the upper surface of the main body 1. The length of the protrusion 11 is the same as the length of the main body 1. The remaining width of the upper surface of the main body 1 is half the width of the protrusion 11. The protrusion 11 and the main body 1 are fixedly arranged. A T-shaped groove 14 is provided inside the left side of the main body 1.

[0020] Meanwhile, a T-shaped groove 14 is also provided on the left side of the protrusion 11, and round holes 12 are provided on the left and right sides of the main body 1. The round holes 12 are arranged linearly at equal intervals. There are a total of six round holes 12, which reduces the weight and the load on the structure, and can also improve the heat insulation performance.

[0021] Furthermore, a bottom groove 16 is provided below the main body 1. The bottom groove 16 extends upward and its width is the same as that of the protrusion 11, so that it can fit better and avoid excessive gaps that could cause problems. A T-shaped block 13 is provided on the right side of the main body 1. The T-shaped block 13 is fixedly provided on the right side of the main body 1. The T-shaped block 13 and the T-shaped groove 14 have the same shape and can be smoothly inserted and fitted.

[0022] The length of the T-shaped block 13 is the same as the length of the upper surface of the bottom groove 16 to the protrusion 11. A bottom block 17 is fixedly installed inside the bottom groove 16. The bottom block 17 extends downward. A top groove 15 is provided above the protrusion 11. The top groove 15 and the bottom block 17 have the same shape. The bottom block 17 can be inserted into the top groove 15, thereby making the main body 1 more stable.

[0023] The main body 1 is fixed front and back by the cooperation between the T-shaped blocks 13 and T-shaped grooves 14. The stacking from top to bottom makes it easier to assemble. The round holes 12 effectively reduce the heat conduction rate, improve the overall heat preservation effect, reduce heat loss, improve energy utilization efficiency, reduce cracks or breaks caused by drastic temperature changes, such as alternating hot and cold, extend the service life of refractory bricks, and reduce maintenance frequency.

[0024] By fitting together the bottom groove 16 and the bottom block 17, the left and right swaying caused by the connection of the main body 1 is reduced, the force borne by the T-groove 14 is also reduced, the T-groove 14 is prevented from breaking, and the service life of the refractory brick is extended.

[0025] Instructions for use: Place the main body 1 in the usage position. When horizontal extension is required, the operator simply picks up the main body 1 and aligns the T-shaped block 13 with the T-shaped groove 14 to form a mortise and tenon connection. When stacking upwards, align the bottom groove 16 of the main body 1 with the top groove 15 to prevent left and right swaying and make it more stable.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
