Description

Technical Field

[0001] This utility model relates to the field of clay brick technology, specifically to a high-strength clay brick. Background Technology

[0002] Clay bricks, also known as sintered bricks, are small man-made building blocks. They are made from clay, including shale, coal gangue and other powders, as the main raw materials. The clay is processed, shaped, dried and fired. They can be solid or hollow. Dense clay bricks are high-density clay bricks with added calcined shale in the raw materials. They have a porosity of less than 18% and a bulk density of more than 2.2 g / cm3. The lower the porosity, the stronger the wear resistance and erosion resistance.

[0003] A search revealed application number CN202121097596.3, entitled "A High-Strength, High-Density Clay Brick." This application addresses the problem that existing dense clay brick stacking processes are cumbersome, requiring mortar to be applied to the surface and sides of each layer of bricks, resulting in high labor intensity for construction workers and generally low brick strength after stacking. The solution involves installing positioning posts and grooves at the top and bottom of the dense clay bricks for interlocking, while using mortise and tenon joints on both sides. During stacking, the upper and lower bricks can be connected via the positioning posts and grooves. The positioning groove provides initial engagement and positioning, preventing brick shifting during stacking and simplifying the process. This makes stacking easier and faster. Once the required height is reached, a reinforcing rib, equal in length to the stacked height, is inserted into the pouring hole of the positioning post. Cement is then poured into the hole to increase the longitudinal connection strength of the bricks. When stacking side bricks, mortar is applied to the first dovetail tenon on one side of the brick, connecting it to the first dovetail protrusion on the other side via a tenon-and-mortise joint. Simultaneously, the first dovetail tenon and the first dovetail protrusion... The interior of the brick has a second dovetail protrusion and a second dovetail tenon, which provides a double-locking effect during fixing, further improving the lateral connection strength of the bricks. The two connection structures work together to solve the problem that the existing dense clay brick stacking process is relatively cumbersome, requiring mortar to be applied to the surface and sides of each layer of bricks, which is labor-intensive for construction workers and results in generally weak brick strength after stacking. However, the clay bricks in this application are hollow bricks, which are generally larger than traditional red bricks. Therefore, it is difficult for workers to hold them with one hand during construction. They need to move the bricks with both hands after spreading the mortar, and they need to put down the trowel when moving them, which is troublesome and affects the construction speed. This application cannot solve the problem that the traditional hollow clay bricks are too large to be handled with one hand, causing inconvenience in construction. At the same time, the cylindrical positioning structure is difficult to align quickly, which also affects the construction efficiency. Further improvements can be made. In addition, the dovetail protrusion tenon structure proposed in this application is very easy to be damaged by collision during transportation, and applying mortar is also troublesome. Further improvements can also be made.

[0005] To address the shortcomings of existing technologies, this invention provides a high-strength clay brick that is more convenient to use, thereby solving the problems mentioned in the background section.

[0006] To achieve the aforementioned advantages of greater ease of use, the specific technical solution adopted by this utility model is as follows:

[0007] A high-strength clay brick includes a dense clay brick body insert strip. The bottom surface of the dense clay brick body has a bottom groove, and the top surface of the dense clay brick body has a protrusion with a thickness of no more than 5 cm. The insert strip includes a web, a first insertion end, and a second insertion end, and the web, the first insertion end, and the second insertion end are an integral structure. Trapezoidal slots are provided through both ends of the dense clay brick body.

[0008] Furthermore, the dense clay brick body has a central hole inside, and multiple sets of central holes are arranged, with the central holes penetrating both ends of the dense clay brick.

[0009] Furthermore, the dense clay brick has recessed holes on both its front and back surfaces, and multiple sets of these recessed holes are densely distributed at equal intervals.

[0010] Furthermore, both the first insertion end and the second insertion end are trapezoidal structures, and the dimensions of the first insertion end and the second insertion end are adapted to the dimensions of the trapezoidal slot.

[0011] Furthermore, the width of the web is equal to the thickness of the mortar between the main body of the dense clay brick in the horizontal direction.

[0012] Furthermore, the height of the bottom groove is greater than the height of the protrusion, and the height difference between the bottom groove and the protrusion is the mortar thickness between the main body of the dense clay brick in the vertical direction.

[0013] Furthermore, the dense clay brick body is made of the same material as the insert strip.

[0014] Furthermore, the depth of the recessed hole is not less than 2 mm.

[0015] Compared with the prior art, this utility model provides a high-strength clay brick with the following beneficial effects:

[0016] (1) This utility model adopts a protrusion and a bottom groove. When laying bricks, workers can place the protrusion upwards. When it is necessary to lay bricks upwards, workers can hold the protrusion and align the bottom groove with the protrusion of the dense clay brick body below to stack it. The insertion of the bottom groove and the protrusion improves the anti-slip ability in the front and back directions. At the same time, it is convenient to position and place, and improves the bricklaying strength. In addition, the thickness of the protrusion is no more than 5cm, which is convenient for workers to hold with one hand. Compared with traditional clay bricks, it is more convenient to operate. In addition, the bottom groove and the protrusion are both long strip structures, which are more convenient to align and splice than cylindrical structures.

[0017] (2) This utility model adopts an independent insert strip, which consists of a web, a first insertion end and a second insertion end. The insert strip is made of the same material as the main body of the dense clay brick. The width of the web is equal to the thickness of the mortar between the main bodies of the dense clay brick. After the two adjacent main bodies of dense clay brick are laid horizontally, the workers can insert the first insertion end and the second insertion end at both ends of the insert strip into the trapezoidal slot to fix the two ends of the main body of the dense clay brick. The insert strip is transported separately, which avoids the problem that the traditional dovetail tenon structure is easily broken and damaged during transportation. At the same time, the workers can carry out mortar construction in accordance with the traditional masonry method, which will not increase the complexity of the mortar masonry process and improve the convenience of use.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a high-strength clay brick is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a high-strength clay brick according to an embodiment of the present invention includes a dense clay brick body 1 and insert strips 6. The bottom surface of the dense clay brick body 1 has a bottom groove 2, and the top surface of the dense clay brick body 1 has a protrusion 3. Both the protrusion 3 and the bottom groove 2 are strip-shaped structures, and the thickness of the protrusion 3 is no more than 5 cm. The insert strip 6 includes a web 8, a first insertion end 9, and a second insertion end 10, and the web 8, the first insertion end 9, and the second insertion end 10 are an integral structure. Trapezoidal slots 4 are provided through both ends of the dense clay brick body 1. During construction, workers can insert... The protrusion 3 is placed upwards. When it is necessary to build upwards, the worker can hold the protrusion 3 and align the bottom groove 2 with the protrusion 3 of the dense clay brick body 1 below to stack it. The interlocking of the bottom groove 2 and the protrusion 3 improves the anti-slip ability in the front and back direction. At the same time, it is convenient to position and place, and improves the masonry strength. In addition, the thickness of the protrusion 3 is no more than 5cm, which is convenient for the worker to hold with one hand. Compared with traditional clay bricks, it is easier to operate. In addition, both the bottom groove 2 and the protrusion 3 are long strip structures, which are easier to align and splice than cylindrical structures.

[0028] In one embodiment, the dense clay brick body 1 has a central hole 5 inside, and multiple sets of central holes 5 are arranged. The central holes 5 penetrate through both ends of the dense clay brick, which is a common structure in the art.

[0029] In one embodiment, the dense clay brick has recessed holes 7 on both the front and back sides, and multiple sets of recessed holes 7 are densely distributed at equal intervals. The depth of the recessed holes 7 is not less than 2mm, which improves the bonding with mortar, improves the quality of surface plastering, eliminates the trouble of later slurry application, and improves construction efficiency.

[0030] In one embodiment, both the first insertion end 9 and the second insertion end 10 are trapezoidal structures, and the dimensions of the first insertion end 9 and the second insertion end 10 are adapted to the dimensions of the trapezoidal slot 4 for easy locking.

[0031] In one embodiment, the width of the web plate 8 is equal to the mortar thickness between the two horizontally adjacent dense clay brick bodies 1. After the two horizontally adjacent dense clay brick bodies 1 are laid, the workers can insert the first insertion end 9 and the second insertion end 10 at both ends of the insert 6 into the trapezoidal slot 4 to fix the two ends of the dense clay brick body 1. The insert 6 is transported separately, avoiding the problem of easy breakage and damage during handling of the traditional dovetail structure. At the same time, the workers can carry out mortar construction according to the traditional masonry method, without increasing the complexity of the mortar masonry process, thus improving the convenience of use.

[0032] In one embodiment, the height of the bottom groove 2 is greater than the height of the protrusion 3, and the height difference between the bottom groove 2 and the protrusion 3 is the mortar thickness between the vertical parts of the dense clay brick body 1, which facilitates mortar spreading.

[0033] In one embodiment, the dense clay brick body 1 and the insert strip 6 are made of the same material and can be manufactured together.

[0034] Working principle:

[0035] During construction, workers can place the protrusions 3 upwards. When upward construction is required, workers can hold the protrusions 3 and align the bottom groove 2 with the protrusions 3 of the dense clay brick body 1 below, then stack them. The interlocking of the bottom groove 2 and the protrusions 3 improves the anti-slip ability in the front-to-back direction, facilitates positioning, and increases the strength of the masonry. Furthermore, the thickness of the protrusions 3 is no more than 5cm, making it easy for workers to hold with one hand. Compared to traditional clay bricks, this makes operation more convenient. Additionally, both the bottom groove 2 and the protrusions 3 are elongated structures, which are easier to align and splice than cylindrical structures. The insert 6 is made of the same material as the dense clay brick body 1, and the width of the web plate 8 is equal to the mortar thickness between the dense clay brick bodies 1. After two adjacent dense clay brick bodies 1 are laid horizontally, the workers can insert the first insertion end 9 and the second insertion end 10 at both ends of the insert 6 into the trapezoidal slot 4 to fix the two ends of the dense clay brick body 1. The insert 6 is transported separately, which avoids the problem of easy breakage and damage during the handling of traditional dovetail tenon structures. At the same time, the workers can carry out mortar construction in accordance with the traditional masonry method, without increasing the complexity of the mortar masonry process and improving the convenience of use.
