Description

Technical Field

[0001] The utility model relates to building materials, more particularly to a hollow brick. Background Art

[0002] Hollow blocks, also known as hollow air blocks or unfired bricks, are a new type of wall material made from fly ash, coal cinders, coal gangue, tailings, chemical slag, concrete, natural sand, or coastal mud (one or more of the above materials) without high-temperature calcination. These bricks require no sintering and can be cured naturally or steam-cured at room temperature.

[0003] When hollow blocks are used to build walls, adjacent bricks are often fixed with concrete. Hollow blocks are equipped with a cavity that connects their top and bottom surfaces in a vertical direction, which can save materials and reduce the weight of the blocks. When building walls, concrete is applied to the top surfaces of these hollow blocks, but some concrete often leaks out of the cavity, resulting in a waste of concrete.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a hollow brick.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a hollow brick, including a brick body, a cavity connecting its top and bottom surfaces is opened on the brick body, and a baffle for closing the cavity is provided on the inner wall of the cavity close to the top surface of the brick body.

[0007] The utility model is further configured as follows: the edge of the blocking piece is fixedly connected to the brick body.

[0008] The utility model is further configured as follows: the baffle is arranged horizontally, the brick body includes an upper pressed body and a lower base, the two sides of the edge of the baffle are respectively pressed against the bottom surface of the upper pressed body and the top surface of the lower base, and the upper pressed body and the lower base are pressed and fixed.

[0009] The utility model is further configured as follows: the thickness of the upper pressed body is between 3CM and 6CM.

[0010] The utility model is further configured as follows: the blocking piece is a waterproof thick paper piece.

[0011] The utility model is further configured as follows: the waterproof thick paper sheet comprises a base paper and a waterproof film laminated on both sides of the base paper.

[0012] The utility model is further configured as follows: the waterproof film is any one of a PET film, an OPP film, a PVC film, and a PE film.

[0013] The utility model is further configured as follows: the brick body is arranged in a sun shape or a mouth shape.

[0014] In summary, the present invention has the following beneficial effects: by setting a baffle, part of the concrete leaking from the top surface of the brick body to the cavity will be blocked by the baffle when the brick wall is built, so that the construction workers can take back the larger pieces of concrete from the baffle, saving concrete and reducing construction costs.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example 1:

[0021] A hollow brick, such as Figure 1 As shown, it includes a brick body 1 arranged in a U shape. The brick body 1 is a lightweight aggregate concrete brick body 1, which is prepared using light coarse aggregate (ceramsite), ordinary sand, cement and water. The lightweight aggregate concrete has the characteristics of light weight, high strength, thermal insulation, shock resistance and anti-seepage. Compared with ordinary concrete, it can reduce its own weight by more than 20 to 30%, so that the brick body 1 has the characteristics of light weight, thermal insulation and fire resistance. The brick body 1 is arranged in a U shape, which reduces the weight of the brick body 1 and facilitates transportation. The cavity 2 in the middle of the brick body 1 also has many advantages such as thermal insulation, heat insulation and sound insulation.

[0022] like Figure 2 As shown, a cavity 2 connecting the top and bottom surfaces of the brick body 1 is provided on the inner wall of the cavity 2 close to the top surface of the brick body 1, and a baffle 3 for closing the cavity 2 is provided. When the brick body 1 is used to build a wall, the construction workers need to apply concrete to every part of the top surface of the brick body 1, that is, except for the cavity 2, the top surface of the brick body 1 needs to be covered with concrete. During this process, part of the concrete is likely to fall into the cavity 2. By providing the baffle 3, when the brick body 1 is used to build a wall, part of the concrete leaking from the top surface of the brick body 1 to the cavity 2 will be blocked by the baffle 3, so that the construction workers can take back larger pieces of concrete from the baffle 3, saving concrete and reducing construction costs.

[0023] like Figure 2 As shown, the edge of the baffle 3 is fixedly connected to the brick body 1, thereby improving the connection strength between the baffle 3 and the brick body 1, making it difficult for the baffle 3 to separate from the brick body 1, and the baffle 3 is not easy to fall off during the transportation of the brick body 1. Furthermore, the baffle 3 is arranged horizontally, and the brick body 1 includes an upper pressing body 4 and a lower base 5. The two sides of the edge of the baffle 3 are respectively pressed against the bottom surface of the upper pressing body 4 and the top surface of the lower base 5. The upper pressing body 4 and the lower base 5 are pressed and fixed. During the production process of the brick body 1, the raw material is placed in the lower mold to form the lower base 5, and then the baffle 3 is placed on the lower base 5, and then the raw material is pressed onto the baffle 3 and the lower base through the upper mold. 5, an upper pressing body 4 is formed on the upper pressing body 4, so that the upper pressing body 4 and the lower base 5 are tightly fixed together with the edge of the baffle 3 during the pressing process. The upper pressing body 4 and the lower base 5 are fixed to form the brick body 1, and the baffle 3 is fixed on the brick body 1. The production is more convenient. At the same time, the connection strength between the baffle 3 and the brick body 1 is high, and the thickness of the upper pressing body 4 is between 3CM and 6CM. In this embodiment, the thickness of the upper pressing body 4 is 5CM. On the one hand, the upper pressing body 4 is thick enough to ensure that the baffle 3 does not fall off. On the other hand, the upper pressing body 4 is not too high, so that the baffle 3 is close to the top surface of the brick body 1, and it is more convenient to remove the concrete that falls on the baffle 3.

[0024] Further, such as Figure 2 As shown, the baffle 3 is a waterproof thick paper sheet. Specifically, the waterproof thick paper sheet includes a base paper and a waterproof film composited on both sides of the base paper. The production cost of the paper baffle 3 is low, which can reduce the production cost of the entire hollow brick. Moreover, the waterproof setting ensures that even if the hollow bricks stacked outdoors encounter rainy days, the paper baffle 3 still has a certain degree of support and can block the concrete and prevent it from falling along the cavity 2. The base paper is kraft paper, which has high strength and good supporting ability. The waterproof film is a PET film, which has water-proof ability, can keep the base paper dry, and can maintain the supporting ability of the baffle 3. In some embodiments, the waterproof film can also be any one of OPP film, PVC film, and PE film.

[0025] Example 2:

[0026] A hollow brick, such as Figure 3 As shown, the difference from the first embodiment is that the brick body 1 is arranged in a sun shape, and accordingly, two cavities 2 are arranged on it, and a blocking piece 3 is arranged in each of the two cavities 2. The brick body 1 is arranged in a sun shape, and compared with the brick body 1 arranged in a mouth shape, it is longer and wall construction is faster.

[0027] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
