Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated wall structures, and particularly relates to a prefabricated shear wall with holes and thermal insulation. Background Art

[0002] The prefabricated thermal insulation 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 the building, reduces the on-site operation time and cost, and also improves the environmental protection performance and quality control level of the building. For the built-in thermal insulation board in the wall, there are generally two structural forms. One is the shear wall, that is, the thermal insulation board structure used for the load-bearing wall part of the whole building; the other is the infill wall, that is, the thermal 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 features and applications of the prefabricated thermal insulation wall:

[0003] 1. Modular design: The prefabricated thermal insulation wall adopts modular design, and customizes the size and style according to the specific needs of the building, including different thermal insulation performances, finish materials and colors, so as 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 thermal insulation performance, and can significantly improve the energy efficiency and living comfort of the building.

[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 achieved, ensuring the precision and consistency of each exterior wall panel, thus improving the construction quality and appearance effect of the overall 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 use 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 diverse building requirements.

[0009] Currently, the gypsum boards used in the barrier layer are all solid boards, which are heavy, causing inconvenience in construction, and have poor sound insulation and noise reduction effects. The fixation of the barrier layer and the insulation layer only relies on fasteners, which is unstable and cannot effectively meet the performance requirements of prefabricated walls.

[0010] Therefore, there is an urgent need to design a prefabricated shear wall with perforated insulation wall to solve the problems of inconvenient construction, poor sound insulation and noise reduction effects, and unstable fixation of the two-layer structure caused by the use of solid gypsum boards in existing prefabricated walls.

The fixed pull rod adopts a "U" - shaped structure. The fixed pull rod passes through the fixing plate, the grid, the limiting outer plate, the barrier layer, the mesh, the insulation layer and the limiting inner plate.

[0032] The following will further describe the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1-5 shown, a prefabricated shear wall with perforated insulation wall includes a barrier layer 1, an insulation layer 2, a connecting piece 3, a mesh sheet one 4, a mesh sheet two 5 and a grid frame 6. The barrier layer 1 and the insulation layer 2 are installed on the wall through the connecting piece 3. The barrier layer 1 is made of gypsum board, and the insulation layer 2 is made of an integrated board.

[0034] The barrier layer 1 is located inside the insulation layer 2. Meshes are arranged on both the inner and outer sides of the barrier layer 1. The meshes include a mesh sheet one 4 and a mesh sheet two 5. Both the mesh sheet one 4 and the mesh sheet two 5 are made of steel wire mesh sheets. The mesh sheet two 5 is arranged between the barrier layer 1 and the insulation layer 2, and the mesh sheet one 4 is arranged on the outer wall of the barrier layer 1.

[0035] The barrier layer 1 is provided with a single row of hollow holes 1.1. The hollow holes 1.1 are single - row through holes penetrating the gypsum board. The setting of the hollow holes 1.1 reduces the weight of the overall prefabricated wall, making the construction more convenient. The through - hole design achieves the effect of sound absorption and noise reduction, and the sound insulation effect is better.

[0036] The grid frame 6 is arranged on the outer side of the insulation layer 2. Mounting plates 6.1 are vertically and fixedly installed on both the upper and lower parts of the grid frame 6. The front part of the mounting plate 6.1 is flat, and the flat part of the mounting plate 6.1 is inserted into the insulation layer 2. The connecting piece 3 is connected to the grid frame 6. The connecting piece 3 adopts a similar structure to an improved prefabricated shear wall insulation board support and fixing connecting piece disclosed in Patent Application No. 202121841233.6.

[0037] The tie member 3 is provided with a fixed tie rod 3.1, a limiting outer plate 3.2, a fixing plate 3.3, a buckle 3.4, a waterproof plate 3.6 and a limiting inner plate 3.7. The fixed tie rod 3.1 adopts a "U" - shaped structure, and the "U" - shaped structure is arranged at the cross - intersection of the connecting parts of the grid 6. The two rod bodies of the fixed tie rod 3.1 obliquely pass through the wire mesh holes of two layers of mesh sheets, as Figure 4 shown. The fixed tie rod 3.1 passes through the fixing plate 3.3, the grid 6, the limiting outer plate 3.2, the gypsum board, two layers of mesh sheets, the integrated board and the limiting inner plate 3.7. The gypsum board and the integrated board are clamped between the limiting outer plate 3.2 and the limiting inner plate 3.7. A buckle 3.4 is arranged on the limiting outer 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 outer plate 3.2 are fixedly connected through the buckle 3.4 and the buckle through - hole 3.5.

[0038] At least two groups of the buckle 3.4 and the buckle through - hole 3.5 are provided, and the buckle 3.4 and the buckle through - hole 3.5 are evenly arranged in a square shape along the circumferential direction of the limiting outer plate 3.2 and are used for clamping at the cross - intersection of the connecting parts of the grid 6.

[0039] A waterproof plate 3.6 is also arranged on one side of the fixing plate 3.3. The waterproof plate 3.6 and the fixing plate 3.3 are fixedly connected through a waterproof buckle and the buckle through - hole 3.5 and are used for covering and hiding one end of the fixed tie rod 3.1.

[0040] Waterproof plates 3.6 and waterproof caps 3.9 are respectively arranged at both ends of the fixed tie rod 3.1. On the one hand, it plays a waterproof role after the construction of the whole wall is completed, preventing the phenomenon of water seepage around both ends of the fixed tie rod 3.1; on the other hand, it plays a role in blocking heat transfer. The fixed tie 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 heat - preservation effect of the wall. In this way, the waterproof plate 3.6 and the waterproof cap 3.9 generally made of plastic products play a very good role in blocking heat transfer.

[0041] A barbed structure 3.8 is arranged on the limiting inner plate 3.7. The small - diameter end of the barbed structure 3.8 abuts against the fixed tie rod 3.1. The barbed structure 3.8 increases the friction force between the limiting inner plate 3.7 and the fixed tie rod 3.1, enabling the limiting inner plate 3.7 to better play the role of fixing the integrated board.

[0042] 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 fixing pull rod 3.1 is sequentially passed through the fixing plate 3.3, the grid 6, the limiting outer plate 3.2, the integral plate, the second mesh 5, the gypsum board and the first mesh 4. The two rod bodies of the fixing pull rod 3.1 obliquely pass through the wire mesh holes of the two layers of meshes. The mounting plate 6.1 on the grid 6 is extruded and inserted into the integral plate. Then, the limiting inner plate 3.7 is pushed into the fixing pull rod 3.1, and under the action of the barbed structure 3.8, the integral plate is clamped and fixed. Finally, the nut, the waterproof cap 3.9 and the waterproof plate 3.6 are installed. After the installation is completed, operations such as pouring or applying mortar can be carried out to form a wall.
