Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a high-strength, crack-resistant building exterior wall brick. Background Technology

[0002] Building exterior wall bricks refer to building materials used for the decoration and protection of building facades, widely used in various types of buildings, including residential, commercial, and industrial buildings. However, a major drawback is that while the overlapping interlocking design increases the stability of the bricks, this design typically only considers interlocking in a few directions, neglecting multi-directional interlocking such as left-right and top-bottom, resulting in poor stability between the bricks. To address this drawback, existing technology (application number: 202120471768.2, authorized)... A Chinese patent published on January 14, 2022, discloses a prefabricated building exterior wall brick, which is composed of brick body A and brick body B. Brick body A and brick body B can be interlocked to form a whole brick body. Furthermore, protrusions are provided on the sides of brick body A and brick body B, which can make the brick bodies more stable when stacked vertically and horizontally by interlocking with each other through the protrusions. In addition, grooves A and groove B are also provided on brick body A and brick body B, so that the cavity formed by grooves A and groove B can accommodate heat insulation material and play a role in heat preservation.

[0003] Existing technology uses bricks A and B to interlock and form a single brick, but this single-layer structure results in low overall strength. When the building's exterior wall is subjected to external impacts, such as hail, falling objects, or human collisions, the bricks may experience significant localized impact, leading to breakage. Furthermore, the lack of an insulation layer on the exterior wall bricks increases energy consumption, reduces indoor comfort, and affects the building structure. The absence of a noise reduction layer also causes severe noise interference and degrades sound quality. Therefore, we have proposed a high-strength, crack-resistant exterior wall brick that effectively solves these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength, crack-resistant building exterior wall brick to solve the problems mentioned in the background art, such as the low overall strength caused by the single-layer structure design of the building exterior wall brick, which makes it easy to break under external impact; at the same time, the lack of a heat insulation layer will lead to increased energy consumption, decreased indoor comfort and damage to the building structure; and the lack of a noise reduction layer will cause defects such as large noise interference and poor sound quality, which seriously affect the user experience and building performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, fracture-resistant building exterior wall brick, comprising a brick body, drainage grooves evenly spaced on the front side of the brick body, and a cavity inside the brick body; further comprising: a first rib and a second rib equally spaced inside the cavity, a heat insulation layer bonded to one side of the brick body located inside the cavity, and a noise reduction layer bonded to the other side of the brick body located inside the cavity, and a rubber strip provided on the outer wall of the brick body.

[0006] Preferably, the wall tile body is composed of a base layer, a reinforcing layer and a waterproof layer, wherein the reinforcing layer is bonded to the side of the base layer, and the waterproof layer is bonded to the side of the reinforcing layer away from the base layer.

[0007] Preferably, the base layer is made of high-strength cement-based material, and the reinforcing layer is made of glass fiber mesh material.

[0008] Preferably, the inner wall of the wall brick body is provided with slots at equal intervals around its perimeter, and the inner wall of the slots is provided with blocks, the slots and blocks being arranged in a "T" shape.

[0009] Preferably, the two ends of the first rib and the second rib are fixedly connected to the side of the locking block, and the first rib and the second rib are installed on the inner wall of the cavity through the locking block. The first rib and the second rib are arranged in an arc shape.

[0010] Preferably, the heat insulation layer is made of polyurethane foam, and the noise reduction layer is made of glass wool.

[0011] Preferably, the rubber strip is embedded in the outer wall of the wall tile body, and the rubber strip can improve the waterproof and sealing performance of the wall tile body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the high-strength, crack-resistant building exterior wall brick adopts a novel structural design, the specific details of which are as follows:

[0013] (1) The wall brick body adopts a multi-layer composite structure design. The base layer uses high-strength cement-based materials to provide basic support strength. The reinforcing layer can be glass fiber mesh or carbon fiber cloth, etc. By embedding these reinforcing materials in the base layer, the tensile and tear resistance of the wall brick body is improved. The waterproof layer uses a waterproof coating or waterproof film to prevent water from penetrating into the interior of the wall brick body and avoid the decrease in strength due to water erosion.

[0014] (2) The first rib and the second rib are inserted into the slot by the locking block, so that the two are tightly connected and can work together to withstand external pressure when subjected to force. At the same time, the first rib and the second rib can evenly distribute the external force, effectively improve the load-bearing capacity of the wall brick body, make it more able to withstand external forces such as wind load and seismic force, reduce the risk of damage such as cracking and deformation caused by external forces, and improve the stability and safety of the building exterior wall.

[0015] (3) By setting the heat insulation layer inside the wall brick body, the heat transfer coefficient of the wall brick body can be reduced, achieving the effect of energy saving and heat preservation. At the same time, by using the noise reduction layer, the noise from the outside can be absorbed and reflected, reducing the indoor noise level and improving the comfort of living and working.

[0016] (4) Setting drainage grooves on the wall brick body can effectively guide rainwater out and prevent rainwater from accumulating on the brick surface or in the brick joints, thereby improving the waterproof performance of the exterior wall and reducing problems such as leakage and freeze-thaw damage caused by long-term water accumulation; furthermore, setting rubber strips between the wall brick bodies can buffer the stress caused by temperature changes, wall deformation and other factors, avoid stress concentration that causes the wall brick body to crack or fall off, and at the same time play a sealing role to prevent rainwater, dust and other things from entering the brick joints, thereby improving the waterproof and sealing performance of the wall brick body.

[0024] 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.

[0025] Please see Figures 1-6 This utility model provides the following technical solution: a high-strength, crack-resistant building exterior wall brick;

[0026] Example 1: To address the problems in existing technologies where the single-layer structure of exterior wall bricks results in low overall strength and susceptibility to breakage under impact, and where the lack of a thermal insulation layer 8 leads to increased energy consumption, decreased indoor comfort, and structural damage, while the absence of a noise reduction layer 9 causes significant noise interference and poor sound quality, severely impacting user experience and building performance, the following solution is disclosed for reference. Figures 1-4 and Figure 6 As shown, the wall tile body 1 includes a wall tile body 1 with drainage grooves 2 evenly spaced on the front side and a cavity 3 inside the wall tile body 1. It also includes: a first rib 6 and a second rib 7 evenly spaced inside the cavity 3; slots 4 evenly spaced around the inner wall of the wall tile body 1; and a locking block 5 on the inner wall of the slots 4. The slots 4 and locking blocks 5 are arranged in a "T" shape. The two ends of the first rib 6 and the second rib 7 are fixedly connected to the sides of the locking blocks 5, and the first rib 6 and the second rib 7 are installed on the inner wall of the cavity 3 via the locking blocks 5. The first rib 6 and the second rib 7 are arc-shaped. The wall tile body 1 is composed of a base layer 101, a reinforcing layer 102, and a waterproof layer 103. The reinforcing layer 102 is bonded to the side of the base layer 101, and the waterproof layer 103 is bonded to the side of the reinforcing layer 102 away from the base layer 101. The base layer 101 is made of high-strength cement-based material, and the reinforcing layer 102 is made of fiberglass mesh material.

[0027] The wall brick body 1 adopts a multi-layer composite structure design. The base layer 101 uses high-strength cement-based material to provide basic support strength. The reinforcing layer 102 can improve the tensile and tear resistance of the wall brick body 1. The waterproof layer 103 uses a waterproof membrane to prevent water from penetrating into the interior of the wall brick body 1 and avoid the decrease in strength due to water erosion. Then, by inserting the first rib 6 and the second rib 7 into the slot 4 through the locking block 5, the two are tightly connected to ensure that they can work together to withstand external pressure when subjected to force. At the same time, the first rib 6 and the second rib 7 can evenly distribute the external force, effectively improving the load-bearing capacity of the wall brick body 1, making it more resistant to external forces such as wind load and seismic force, reducing the risk of damage such as cracking and deformation caused by external forces, and improving the stability and safety of the building exterior wall. Furthermore, by setting drainage channels 2 on the wall brick body 1, rainwater can be effectively guided out and prevent rainwater from accumulating on the brick surface or brick joints, thereby improving the waterproof performance of the wall brick body 1 and reducing problems such as leakage and freeze-thaw damage caused by long-term water accumulation.

[0028] Example 2: Unlike Example 1, this example utilizes the insulation layer 8 to reduce the heat transfer coefficient of the wall brick body 1, achieving energy-saving and heat-insulating effects. See details... Figure 4 As shown, a heat insulation layer 8 is bonded to one side of the cavity 3 inside the wall tile body 1, and a noise reduction layer 9 is bonded to the other side of the cavity 3 inside the wall tile body 1. The heat insulation layer 8 is made of polyurethane foam material, and the noise reduction layer 9 is made of glass wool material.

[0029] By setting the heat insulation layer 8 inside the wall brick body 1, the heat transfer coefficient of the wall brick body 1 can be reduced, achieving the effect of energy saving and heat preservation. At the same time, the noise reduction layer 9 can absorb and reflect external noise, reduce indoor noise level, and improve the comfort of living and working.

[0030] Example 3: Unlike Example 2, this example utilizes a rubber strip 10 to improve the waterproof and sealing performance of the wall tile body 1. See details... Figure 5 As shown, a rubber strip 10 is provided on the outer wall of the wall tile body 1. The rubber strip 10 is embedded in the outer wall of the wall tile body 1, and the rubber strip 10 can improve the waterproof and sealing performance of the wall tile body 1.

[0031] Rubber strips 10 are installed between the wall brick bodies 1 to buffer the stress caused by temperature changes, wall deformation and other factors, and avoid stress concentration that could cause the exterior wall bricks to crack or fall off. At the same time, they can also play a sealing role to prevent rainwater, dust and other substances from entering the brick joints and improve the waterproof and sealing performance of the wall brick bodies 1.
