Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated wall structures, and particularly relates to a heat-insulating wall with a double-layer structure of a prefabricated infill wall. Background Technique

[0002] The prefabricated heat-insulating wall is a modern building component widely used in the prefabricated building system. Its characteristic is that the structure and finish of the exterior wall are prefabricated in the factory and then transported to the site for assembly. This method greatly improves the construction efficiency of buildings, reduces the on-site operation time and cost, and also enhances the environmental protection performance and quality control level of buildings. For the built-in insulation board in the wall, there are generally two structural forms. One is the shear wall, that is, the insulation board structure used for the load-bearing wall part of the whole building; the other is the infill wall, that is, the insulation board structure for the non-load-bearing wall part of the building. For the two different wall forms, different fixed assembly structure components are required for fixed installation. The following are some key characteristics and applications of the prefabricated heat-insulating wall:

[0003] 1. Modular design: The prefabricated heat-insulating wall adopts modular design, and customizes the size and style according to the specific needs of the building, including different heat-insulating performances, finish materials and colors, to meet the diverse building styles and functional requirements.

[0004] 2. High-performance materials: The exterior wall panels usually adopt high-performance building materials such as concrete, metal, composite materials, etc. These materials have good weather resistance, fire resistance and heat-insulating and heat-preserving performances, and can significantly improve the energy efficiency and living comfort of buildings.

[0005] 3. Quick installation: Since the exterior wall panels are prefabricated in the factory, only hoisting and splicing are required on site, which greatly reduces the on-site construction time and labor demand and improves the construction efficiency.

[0006] 4. High precision and quality control: Produced in a controlled factory environment, more strict dimension and quality control are realized, ensuring the precision and consistency of each exterior wall panel, thereby improving the overall construction quality and appearance effect of the building.

[0007] 5. Environmental protection and sustainability: The prefabricated exterior wall panels reduce the on-site wet operations, reduce the noise and dust pollution during the construction process. At the same time, due to the efficient utilization and recyclability of materials, it helps to achieve the green and sustainable development goals of the construction industry.

[0008] 6. Convenient maintenance: The modular structure of the exterior wall panels facilitates later maintenance and replacement. In case of damage or aging, only the damaged part needs to be replaced separately without affecting the entire wall. The prefabricated exterior wall panels have a wide range of applications, from residential buildings to commercial complexes, and can be seen in schools, hospitals, and industrial factories. With the continuous development of building technology, the design and materials of prefabricated exterior wall panels are also constantly innovating to meet more complex and diversified building requirements.

[0009] At present, the thermal insulation wall generally adopts a single-layer structure. The single-layer structure plays a role in thermal insulation but cannot play a role in blocking moisture. When assembling two-layer structures, the connection between the two layers is prone to instability and the phenomenon of staggered floors.

[0010] Therefore, there is an urgent need to design a thermal insulation wall with a double-layer structure for prefabricated infill walls to solve the problems of poor blocking effect of the existing single-layer structure of prefabricated walls and unstable fixation of the two-layer structure. Summary of the Invention

[0011] Aiming at the problems existing in the prior art, the purpose of the present utility model is to provide a thermal insulation wall with a double-layer structure for prefabricated infill walls.

[0012] The technical solution adopted by the present utility model to solve its technical problems is: A thermal insulation wall with a double-layer structure for prefabricated infill walls, including a barrier layer, a thermal insulation layer, and a connecting member. The barrier layer and the thermal insulation layer form a thermal insulation wall through the connecting member. The connecting member includes a fixed pull rod and a connecting and fixing structure. The barrier layer is located inside the thermal insulation layer. Mesh sheets are arranged on both the inner and outer sides of the barrier layer. A grid is arranged on the outer side of the thermal insulation layer. The connecting and fixing structures are connected to both the grid on the outer side of the thermal insulation layer and the outer mesh sheet of the barrier layer. The fixed pull rod is installed between the connecting and fixing structures. An inclined stay wire is connected between the inner side of the grid and the outer mesh sheet of the barrier layer.

[0013] Specifically, the mesh sheets include mesh sheet one and mesh sheet two. Both mesh sheet one and mesh sheet two adopt steel wire mesh sheets. Mesh sheet two is arranged between the barrier layer and the thermal insulation layer, and mesh sheet one is arranged on the outer side of the barrier layer.

[0014] Specifically, the inclined stay wires are arranged crosswise. The inclined stay wires adopt steel wires. One end of the inclined stay wire is connected to the grid, and one end of the inclined stay wire is connected to mesh sheet one.

One end of the "U" - shaped structure of the fixed pull rod is installed on the grid through one group of connecting and fixing structures, and the two rod ends of the fixed pull rod are installed on mesh sheet one through the other group of connecting and fixing structures.

[0016] Specifically, the pulling and fixing structure includes a limiting side plate, a fixing plate, a buckle, and a waterproof plate. The fixing pull rod passes through the fixing plate, the grid frame, the limiting side plate, the thermal insulation layer, the second mesh sheet, the barrier layer, the limiting side plate, the first mesh sheet, and the fixing plate. The barrier layer and the thermal insulation layer are clamped between the two limiting side plates. Buckles are arranged on the limiting side plates, card slots are arranged on the buckles, buckle through holes adapted to the buckles are arranged on the fixing plate, and the fixing plate and the limiting side plate are fixedly connected through the buckles and the buckle through holes.

[0017] Specifically, at least two groups of the buckles and the buckle through holes are provided, and the buckles and the buckle through holes are uniformly arranged in a square shape along the circumferential direction of the limiting side plate.

[0018] Specifically, a waterproof plate is further arranged on one side of the fixing plate, and the waterproof plate and the fixing plate are fixedly connected through waterproof buckles and buckle through holes.

[0019] Specifically, the barrier layer is made of gypsum board, and the thermal insulation layer is made of an integrated board.

[0020] The utility model has the following beneficial effects:

[0021] The thermal insulation wall body of the assembled filler wall double-layer structure designed by the utility model adopts a moisture-proof and fire-proof gypsum board and a heat-insulating integrated board to form an integral structure through a grid frame, double mesh sheets, and a pulling and connecting member. The gypsum board and the integrated board are fixed between the grid frame and the outer mesh sheet through diagonal tension web wires. The fixing pull rod is obliquely inserted into the mesh holes of the two-layer mesh sheet. The two-layer fixing structure is more stable and reliable, and is integrally assembled on site, which is convenient for construction and improves the construction efficiency.

[0028] The following will further describe in detail the technical solutions in the embodiments of the present utility model clearly and completely in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0029] As Figures 1-4 shown, a heat-insulating wall with a double-layer structure of prefabricated infill walls includes a barrier layer 1, a heat-insulating layer 2, a connecting member 3, a first mesh 4, a second mesh 5, a grid 6 and diagonal tension filaments 7. The barrier layer 1 and the heat-insulating layer 2 form a heat-insulating wall through the connecting member 3. The barrier layer 1 is made of gypsum board, and the heat-insulating layer 2 is made of an integrated board.

[0030] The barrier layer 1 is located inside the heat-insulating layer 2. Meshes are arranged on both the inner and outer sides of the barrier layer 1. The meshes include the first mesh 4 and the second mesh 5. Both the first mesh 4 and the second mesh 5 are made of steel wire mesh sheets. The second mesh 5 is arranged between the barrier layer 1 and the heat-insulating layer 2, and the first mesh 4 is arranged on the outer side of the barrier layer 1.

[0031] The connecting member 3 includes a fixed pull rod 3.1 and a connecting and fixing structure. The connecting member 3 adopts a similar structure to an improved prefabricated infill wall heat-insulating board support and fixing connecting member disclosed in Patent Application No. 202121841209.2. A grid 6 is arranged on the outer side of the heat-insulating layer 2. Connecting and fixing structures are connected to both the grid 6 and the outer first mesh 4 of the barrier layer 1, and the fixed pull rod 3.1 is installed between the connecting and fixing structures.

[0032] There are two groups of connecting and fixing structures. The fixed pull rod 3.1 adopts a "U" - shaped structure. One end of the "U" - shaped structure of the fixed pull rod 3.1 is installed on the grid 6 through one group of connecting and fixing structures, and the two pull rod ends of the fixed pull rod 3.1 are installed on the first mesh 4 through the other group of connecting and fixing structures.

[0033] The connecting and fixing structure includes a limiting side plate 3.2, a fixing plate 3.3, a buckle 3.4 and a waterproof plate 3.6. The fixed pull rod 3.1 passes through the fixing plate 3.3, the grid 6, the limiting side plate 3.2, the heat-insulating layer 2, the second mesh 4, the barrier layer 1, the limiting side plate 3.2, the first mesh 4 and the fixing plate 3.3. The barrier layer 1 and the heat-insulating layer 2 are clamped between the two limiting side plates 3.2. A buckle 3.4 is arranged on the limiting side plate 3.2, a clamping groove is arranged on the buckle 3.4, and a buckle through hole 3.5 adapted to the buckle 3.4 is arranged on the fixing plate 3.3. The fixing plate 3.3 and the limiting side plate 3.2 are fixedly connected through the buckle 3.4 and the buckle through hole 3.5.

[0034] There are at least two groups of the buckle 3.4 and the buckle through hole 3.5. The buckle 3.4 and the buckle through hole 3.5 are uniformly arranged in a square shape along the circumferential direction of the limiting outer side plate 3.2 and are used to be stuck at the cross - intersection of the connecting parts of the grid 6.

[0035] On one side of the fixing plate 3.3, a waterproof plate 3.6 is also provided. The waterproof plate 3.6 is fixedly connected to the fixing plate 3.3 through waterproof buckles and buckle through-holes 3.5, and is used to cover and hide one end of the fixed pull rod 3.1.

[0036] Waterproof plates 3.6 are respectively arranged at both ends of the fixed pull rod 3.1. On the one hand, it plays a waterproof effect after the construction of the entire wall is completed, preventing water seepage around both ends of the fixed pull rod 3.1; on the other hand, it plays a role in blocking heat transfer. The fixed pull rod 3.1 is generally made of metal, especially threaded steel. If its two ends are directly exposed or close to both sides of the wall, heat transfer will inevitably occur, resulting in a discount in the insulation effect of the wall. In this way, the waterproof plate 3.6 generally made of plastic products plays a very good role in blocking heat transfer.

[0037] Diagonal stay web wires 7 are connected between the inner side of the grid 6 and the first outer mesh sheet 4 of the barrier layer 1. The diagonal stay web wires 7 are arranged in a cross pattern. The diagonal stay web wires 7 are made of steel wires. One end of the diagonal stay web wires 7 is connected to the grid 6, and one end of the diagonal stay web wires 7 is connected to the first mesh sheet 4.

[0038] The working principle of the present utility model is as follows: First, the fixing plate 3.3 and the limiting outer plate 3.2 are fixedly clamped at the cross intersection of the connecting part of the grid 6. Then, the fixed pull rod 3.1 is sequentially passed through the fixing plate 3.3, the grid 6, the limiting side plate 3.2, the integral board, the second mesh sheet 4, the gypsum board, the limiting side plate 3.2, the first mesh sheet 4 and the fixing plate 3.3. The two rod bodies of the fixed pull rod 3.1 obliquely pass through the wire mesh holes of the two layers of mesh sheets. The two sets of connecting and fixing structures clamp and fix the integral board and the gypsum board. Finally, the waterproof plate 3.6 is installed. After the installation is completed, operations such as pouring or applying mortar can be carried out to form a wall.

Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model.
