Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically to a building exterior wall. Background Technology

[0002] Building exterior wall waterproofing should have the basic function of preventing rainwater and snowmelt from penetrating the wall, and should also have properties such as freeze-thaw resistance, high and low temperature resistance, and wind load resistance. In order to ensure the strength and durability of the wall, moisture-proof and waterproof measures should be taken for the exterior walls of the building, especially the plinth. Selecting good waterproof materials and construction methods is a prerequisite for ensuring a good sanitary environment indoors.

[0003] A search revealed Chinese patent CN218990533U, which discloses a building exterior wall structure, comprising a first base block; a second base block; a thermal insulation layer disposed on one side of the first base block; a thermal insulation layer disposed between the first and second base blocks to block heat exchange between them; and a reinforcing support block embedded in the upper surface of the thermal insulation layer to support the space between the first and second base blocks. This invention, by adding a thermal insulation layer in the middle of the exterior wall, effectively blocks heat conduction between the outside and the bathroom; the reinforcing support block ensures uniform stress distribution between the first and second base blocks, supporting the thermal insulation layer and preventing deformation that could affect the wall's quality.

[0004] Although the building exterior wall structure of this utility model can insulate heat, it lacks a fireproof structure, which causes the wall to burn very quickly when exposed to fire, seriously affecting the quality of the wall structure and failing to meet the usage requirements. Therefore, a building exterior wall is proposed to solve the problems mentioned above. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a building exterior wall with the advantages of strong practicality and good protection effect, which solves the problem that the lack of fireproof structure of the wall leads to the wall burning very quickly after being exposed to fire.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a building exterior wall, comprising an exterior wall structure, wherein the exterior wall structure comprises a first base block, a second base block, and a thermal insulation layer disposed between the first base block and the second base block, and a protective structure is provided on the side of the first base block away from the thermal insulation layer;

[0007] The protective structure includes a fireproof board, a fiber mesh, and a heat insulation layer arranged sequentially from the outside to the inside. The side of the fireproof board away from the fiber mesh is coated with fire-retardant paint.

[0008] Furthermore, the thermal insulation layer includes a thermal insulation board, a sound insulation board disposed on one side of the thermal insulation board, and a heat insulation board disposed on one side of the sound insulation board, wherein the thermal insulation board, the sound insulation board, and the heat insulation board are stacked and combined in sequence.

[0009] Furthermore, the insulation board and the sound insulation board are bonded together with strong adhesive, and the sound insulation board and the heat insulation board are bonded together with strong adhesive.

[0010] Furthermore, two waterproof plates are provided between the first base block and the second base block, and the two waterproof plates are respectively located on both sides of the thermal insulation layer. One waterproof plate is located between the first base block and the thermal insulation layer, while the other waterproof plate is located between the second base block and the thermal insulation layer.

[0011] Furthermore, a reinforcing support frame for reinforcement is provided between the thermal insulation layer and the waterproof plate near the second base block, and the reinforcing support frame is embedded in the outer surface of the thermal insulation layer.

[0012] Furthermore, the reinforcing support frame is used to support the first base block and the second base block.

[0013] Furthermore, the outer surface of the thermal insulation layer is provided with a grid groove, the grid groove is grid-shaped, and the size of the reinforcing support block matches the structure of the grid groove.

[0014] Furthermore, the insulation board is polyurethane foam, the sound insulation board is damping sound insulation cotton, and the heat insulation board is a nano-composite heat insulation board, and the three are connected and fixed together by strong adhesive.

[0015] Compared with the prior art, the present invention provides a building exterior wall with the following advantages:

[0016] 1. The building's exterior walls are protected by fireproof boards and fireproof coatings. The fireproof coating used is Class H, a thick-film type with low thermal conductivity and excellent fire resistance. It can provide fire protection for the exterior wall structure, greatly improving the fire resistance of the exterior wall structure. This results in advantages such as strong practicality and good protective effect, solving the problem of walls lacking fireproof structures, which leads to very rapid combustion when exposed to fire.

[0017] 2. The building's exterior walls, including both the insulation layer and the insulation board, have thermal insulation properties. The optimized combination of these two materials, along with the thermal insulation properties of the insulation board, prevents the exterior walls from peeling off under long-term external erosion. This also avoids exposing the internal thermal insulation layer of the exterior wall structure, which would otherwise lead to a decrease in thermal insulation performance and loss of fire resistance.

[0022] 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.

[0023] Please see Figure 1-3 An exterior wall of a building includes an exterior wall structure 1. The exterior wall structure 1 includes a first base block 100, a second base block 110, and a thermal insulation layer 130 disposed between the first base block 100 and the second base block 110. A protective structure 2 is provided on the side of the first base block 100 away from the thermal insulation layer 130. The thermal insulation layer 130 includes an insulation board 1301, a sound insulation board 1302 disposed on one side of the insulation board 1301, and a heat insulation board 1303 disposed on one side of the sound insulation board 1302. The insulation board 1301, the sound insulation board 1302, and the heat insulation board 1303 are stacked and combined in sequence.

[0024] The insulation board 1301 and the sound insulation board 1302 are bonded together with strong adhesive, and the sound insulation board 1302 and the heat insulation board 1303 are bonded together with strong adhesive. Two waterproof boards 120 are provided between the first base block 100 and the second base block 110, and the two waterproof boards 120 are respectively located on both sides of the heat insulation layer 130. One waterproof board 120 is located between the first base block 100 and the heat insulation layer 130, and the other waterproof board 120 is located between the second base block 110 and the heat insulation layer 130.

[0025] Furthermore, a reinforcing support frame 140 for reinforcement is provided between the thermal insulation layer 130 and the waterproof plate 120 near the second base block 110, and the reinforcing support frame 140 is embedded in the outer surface of the thermal insulation layer 130.

[0026] It should be noted that the reinforcing support frame 140 is used to support the first base block 100 and the second base block 110. The insulation board 1301 is polyurethane foam, the sound insulation board 1302 is damping sound insulation cotton, and the heat insulation board 1303 is a nano-composite heat insulation board, and the three are connected and fixed together by strong adhesive. The heat insulation board 1303 is located on the outermost side.

[0027] In this embodiment, by adding a thermal insulation layer 130 in the middle of the outer wall structure 1, heat conduction between the outside and the inside of the wall can be effectively blocked. The reinforced support frame 140 can ensure that the force between the first base block 100 and the second base block 110 is uniform, and plays a supporting role for the thermal insulation layer 130, preventing the thermal insulation layer 130 from deforming under stress and affecting the quality of the wall. The connection between the layers of the wall is bonded with cement mortar, which further improves the connection strength between the layers to prevent the layers of the assembled wall from separating from each other.

[0028] In this embodiment, a grid groove 1304 is formed on the outer surface of the thermal insulation layer 130. The grid groove 1304 is grid-shaped, and the reinforcing support block 140 matches the size and structure of the grid groove 1304. The grid groove 1304 is formed on the upper surface of the thermal insulation layer 130, and the grid groove 1304 is the same size and structure as the reinforcing support block 140, facilitating the installation of the reinforcing support block 140 into the thermal insulation layer 130, thereby enhancing the internal support strength of the wall and ensuring product quality.

[0029] In this embodiment, the protective structure 2 includes a fireproof board 200, a fiber mesh 210 and a heat insulation layer 220 arranged sequentially from the outside to the inside. The side of the fireproof board 200 away from the fiber mesh 210 is coated with fireproof paint 230.

[0030] It should be noted that the heat insulation coating 230 uses a Class H fire retardant coating, which is a thick-film fire retardant coating with a coating thickness of 8-50 mm. It has a granular surface, low density, and low thermal conductivity. In addition, its heat resistance limit can reach 0.5-3 hours, and it has excellent fire resistance.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the fireproof board 200 and the fireproof coating 230 are used. The fireproof coating 230 is a Class H fireproof coating, a thick-film type with low thermal conductivity and excellent fire resistance. It can provide fire protection for the exterior wall structure 1. Both the insulation layer 220 and the insulation board 1303 have heat insulation properties. The optimized combination of the two materials, along with the heat insulation properties of the insulation board, prevents the wall coating from peeling off under long-term external erosion. It also avoids the problem of the insulation layer 130 inside the exterior wall structure 1 being exposed, which would lead to a decrease in heat insulation effect and loss of fire resistance.
