Description

Technical Field

[0001] The utility model relates to building materials, and more specifically, to a heat-insulating hollow block brick. Background Art

[0002] The hollow block brick is also called hollow aerated block brick or non-fired brick. A new type of wall material made from fly ash, coal cinder, coal gangue, tailings slag, chemical slag, concrete or natural sand, sea mud, etc. (one or several of the above raw materials) without high-temperature calcination is called non-fired brick. The hollow block brick does not need to be sintered and can be naturally cured or cured at normal temperature.

[0003] A composite autoclaved aerated concrete heat-insulating block disclosed in a Chinese patent with the publication number CN205012548U has the following technical key points: including a block body, the block body includes a heat-insulating cavity surrounded by autoclaved aerated concrete, ribs are arranged in the heat-insulating cavity, a heat-insulating board is installed in the cavity of the heat-insulating cavity, a connecting groove is arranged on one side of the block body, and a connecting convex block is arranged on the other side of the block body.

[0004] When the existing blocks are produced, the installation of the heat-insulating board is rather troublesome, the production cost is relatively high, and the connection strength between the block body and the heat-insulating board is also insufficient.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a heat-insulating hollow block brick.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a heat-insulating hollow block brick, including a block, an injection cavity communicating with the top surface and the bottom surface of the block is opened in the block, a foaming glue layer formed by the expansion and curing of a foaming agent is filled in the injection cavity, and cutting surfaces flush with the top surface and the bottom surface of the block are respectively arranged on the top surface and the bottom surface of the foaming glue layer.

[0008] The utility model is further arranged as follows: a cutting groove communicating with the injection cavity is opened inward on the top surface or the bottom surface of the block, and the left and right ends of the cutting groove are respectively located outside the left and right sides of the injection cavity.

[0009] The utility model is further arranged as follows: the foaming glue layer is a polyurethane foaming glue layer.

[0010] The utility model is further arranged as follows: there are two injection cavities, and the two injection cavities are respectively located on both sides of the block.

[0011] The utility model is further arranged as follows: the block is arranged in a "day" shape or a "mouth" shape.

[0012] The utility model is further configured as: the building block is a lightweight aggregate concrete building block.

[0013] In summary, the utility model has the following beneficial effects: there is no need to install a separate insulation board on the building block. Instead, the building blocks can be stacked vertically, so that the injection cavities on multiple building blocks are interconnected. Then, a foaming agent is injected, so that the foaming agent expands in multiple injection cavities and is firmly fixed to the inner wall of the injection cavity. Then, only by cutting the edges of adjacent building blocks, the foamed rubber after expansion and curing can be cut off to form a foamed rubber layer located in the injection cavity. The foamed rubber layer can play a role in heat preservation. At the same time, the production cost of the heat-insulating building block produced in this way is relatively low, the production is relatively efficient, and the connection strength between the foamed rubber layer and the building block is also sufficient.

[0018] The following combines the drawings and embodiments to describe the present utility model in detail.

[0019] Embodiment 1:

[0020] A heat-insulating hollow building block brick, as Figure 1 shown, includes a building block 1. The building block 1 is a lightweight aggregate concrete building block, which is prepared by using lightweight coarse aggregate (ceramsite), ordinary sand, cement and water. The lightweight aggregate concrete has the characteristics of light self-weight, high strength, heat insulation, shock resistance and impermeability. Compared with ordinary concrete of the same grade, the self-weight can be reduced by more than 20-30%, so that the building block 1 has the characteristics of light self-weight, heat insulation and good fire resistance. The building block 1 is arranged in a Japanese character shape, which can keep the building block 1 with a high bearing capacity while reducing the weight of the building block 1, facilitating transportation, and the cavity in the building block 1 also has many advantages such as heat insulation, sound insulation, etc.

[0021] As Figure 1 and Figure 2As shown in the figure, an injection cavity 2 is formed inside the building block 1, which is communicated with its top surface and bottom surface. The injection cavity 2 is arranged in a cuboid shape, and a foamed rubber layer 3 formed by the expansion and curing of a foaming agent is filled inside the injection cavity 2. The top surface and the bottom surface of the foamed rubber layer 3 are provided with cut surfaces flush with the top surface and the bottom surface of the building block 1 respectively. Instead of installing a separate insulation board on the building block 1, the building blocks 1 can be stacked vertically, so that the injection cavities 2 on multiple building blocks 1 are communicated with each other. Then, a glue gun is inserted into the injection cavity 2 to inject the foaming agent, so that the foaming agent expands in multiple injection cavities 2 and is firmly fixed to the inner wall of the injection cavity 2. Then, by simply cutting the edges of adjacent building blocks 1, the expanded and cured foamed rubber can be cut off to form the foamed rubber layer 3 located inside the injection cavity 2. The foamed rubber layer 3 can play a role in heat preservation. At the same time, the production cost of the heat-insulating building block 1 produced in this way is relatively low, the production is relatively efficient, the connection strength between the foamed rubber layer 3 and the building block 1 is sufficient, and the foamed rubber layer 3 is a polyurethane foamed rubber layer. As a new type of heat-insulating material, polyurethane foamed rubber has excellent heat-insulating performance and durability. The polyurethane foamed rubber layer can form a closed heat-insulating layer to prevent the transfer and loss of heat. Compared with traditional heat-insulating materials, polyurethane foamed rubber has a higher heat-insulating effect, which can ensure the temperature stability inside the building. At the same time, the polyurethane foamed rubber layer can also effectively prevent the intrusion of water vapor and oxygen, and maintain the dryness and stability inside the building.

[0022] Further, as Figure 1 and Figure 2 shown, a cutting groove 4 communicating with the injection cavity 2 is formed inwardly on the top surface or the bottom surface of the building block 1. The left and right ends of the cutting groove 4 are respectively located outside the left and right sides of the injection cavity 2. The setting of the cutting groove 4 enables the building blocks 1 in the stacked state to be separated by inserting a cutting tool into the cutting groove 4 to cut the foamed rubber layer 3. The setting of the cutting groove 4 facilitates cutting the foamed rubber layer 3, thereby facilitating the separation of multiple building blocks 1. And because the length of the cutting groove 4 is longer than the length of the injection cavity 2, the entire foamed rubber layer 3 can be cut transversely and completely.

[0023] As Figure 1 and Figure 2 shown, there are two injection cavities 2, and the two injection cavities 2 are respectively located on both sides of the building block 1. The injection cavities 2 are arranged on both sides of the building block 1, so that two foamed rubber layers 3 can be arranged, thereby further improving the heat-insulating performance of the building block 1.

[0024] Embodiment 2:

[0025] As Figure 3 shown, the difference from Embodiment 1 is that the building block 1 is arranged in a "mouth" shape. Compared with the building block 1 arranged in a "day" shape, it has a smaller volume and different building usage scenarios. Similarly, as the heat-insulating layer, the foamed rubber layer 3 has a relatively low production cost, relatively efficient production, and sufficient connection strength between the foamed rubber layer 3 and the building block 1.

[0026] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
