Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to a novel hollow double-skin wall. Background Technology

[0002] Precast walls are increasingly widely used because they are easy to manufacture in factories and then transported to construction sites for assembly into prefabricated buildings, which improves construction efficiency. However, complete precast walls are relatively heavy, making transportation inconvenient, especially for export. The weight of the precast walls increases transportation difficulty, limits the quantity that can be transported, or increases transportation costs, thus restricting the application and development of prefabricated buildings. Utility Model Content

[0003] To overcome the above problems, this utility model provides a novel hollow double-skin wall.

[0004] This utility model is achieved by the following solution: The novel hollow double-skin wall includes a wall frame and two barrier components. The two barrier components are respectively fixed on both sides of the wall frame in the thickness direction to form a filling cavity between the two barrier components. The wall frame has a pouring port on one side in the width direction that communicates with the filling cavity.

[0005] The novel hollow double-skin wall described above also includes a wall skin layer, which is fixed to the outside of the wall frame and the barrier.

[0006] The novel hollow double-skin wall described above includes a barrier element comprising a wall mesh or a steel mesh.

[0007] The novel hollow double-skin wall described above includes two horizontal supports spaced apart along the width direction and multiple vertical supports fixedly connected between the two horizontal supports. The multiple vertical supports are spaced apart along the length direction and are located between the two barrier members.

[0008] As described above, the new type of hollow double-skin wall uses square steel pipes for both the horizontal and vertical supports.

[0009] In the novel hollow double-skin wall described above, both the horizontal and vertical supports are made of lightweight steel.

[0010] As described above, the novel hollow double-skin wall has a connecting part on the vertical support, and the novel hollow double-skin wall has an assembly groove at the connecting part, with the connecting part located within the assembly groove.

[0011] As described above, the novel hollow double-skin wall includes a connecting part comprising a plurality of connecting steel rings fixedly distributed at intervals on the vertical support. The connecting steel rings are U-shaped and have two connecting pieces distributed at intervals on them. The two connecting pieces are fixedly disposed on both sides of the vertical support to fix the connecting steel rings to the vertical support.

[0012] As described above, the novel hollow double-skin wall panel includes a first H-groove on the vertical support. When two novel hollow double-skin wall panels are connected, the first H-grooves on the two novel hollow double-skin wall panels are correspondingly arranged, forming a connecting cavity between the first H-grooves on the novel hollow double-skin wall panels. A second H-groove is provided in the connecting cavity. Both the first and second H-grooves are C-shaped, and two second H-grooves are provided in the connecting cavity to connect the corresponding ends of the two first H-grooves respectively, so that the two first H-grooves and the two second H-grooves form a frame-shaped structure.

[0013] As described above, in the novel hollow double-skin wall, the vertical support has a through cavity, the vertical support is connected to the horizontal support, and the pouring port on the horizontal support is connected to the through cavity of the vertical support.

[0014] Compared with the prior art, this application has the following advantages: This invention features two barrier components on a wall frame, creating a filling cavity between them. During the factory prefabrication of this double-skin wall, a wall skin layer is first poured onto the outside of the wall frame and barrier components using a mold, forming wall skin layers on both sides of the wall frame's thickness, with a filling cavity remaining between the two layers. This structure significantly reduces the weight of the factory-prefabricated double-skin wall compared to traditional prefabricated walls, facilitating handling and transportation, reducing export difficulties and costs, and enabling the transport of a larger quantity of walls under the same conditions. Once the wall arrives at the construction site, workers can pour concrete or other insulation materials into the filling cavity through the pouring port, creating a wall suitable for local conditions. This wall can then be directly used for building assembly. The process is simple, widely applicable, and allows for flexible adjustments by construction workers, helping to reduce overall construction costs, improve construction efficiency, and thus broaden the application scope of prefabricated buildings, promoting their further development.

[0021] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] When ordinal numbers such as "first" and "second" are mentioned in the embodiments of this application, unless they actually express the meaning of order according to the context, they should be understood as being used only for distinction.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] Example 1: As Figures 1 to 4As shown, this embodiment discloses a novel hollow double-skin wall, including a wall frame 1 and two barrier members 2. The two barrier members 2 are respectively fixed on both sides of the wall frame 1 in the thickness direction, forming a filling cavity 3 between the two barrier members 2. The wall frame 1 has a casting port 4 communicating with the filling cavity 3 on one side in the width direction. The novel hollow double-skin wall also includes a wall skin layer 7, which is fixed to the outside of the wall frame 1 and the barrier members 2. In this embodiment, by setting two barrier members 2 on the wall frame 1, a filling cavity 3 is formed between them. During the prefabrication of this embodiment's double-skin wall in the factory, the wall skin layer 7 can be cast on the outside of the wall frame 1 and the barrier members 2 using a mold, thereby forming the wall skin layer 7 on both sides of the wall frame 1 in the thickness direction, and retaining the filling cavity 3 between the two wall skin layers 7. By adopting this structure, the double-skin wall of this embodiment, manufactured in the factory, is significantly lighter than traditional precast walls, facilitating handling and transportation, reducing the difficulty and cost of export transportation, and enabling the transport of a larger quantity of walls under the same conditions. Once the wall is delivered to the construction site, construction workers can pour concrete or other insulation materials into the filling cavity 3 through the pouring port 4, according to local environmental requirements, to form a wall suitable for local conditions and directly for building assembly. If the wall is used in low-rise buildings without higher support strength requirements, clay or other insulation materials can be directly poured into the filling cavity 3 to improve the wall's insulation performance; if it is required for high-rise buildings, concrete can be directly poured to ensure sufficient strength. The operation is simple, the application range is wide, and construction workers can flexibly choose and adjust the design, helping to reduce overall construction costs and improve construction efficiency.

[0025] Furthermore, the barrier element 2 includes a wall mesh or a steel mesh. In this embodiment, the use of a wall mesh or steel mesh can both replace steel bars in the wall to improve the wall's supporting strength and create filling cavities 3 in the wall frame 1 during the casting of the wall skin layer 7, thus meeting usage requirements. Specifically, the barrier element 2 is fixed to the wall frame 1 by welding or fasteners.

[0026] Furthermore, the wall frame 1 includes two horizontal supports 11 spaced apart along the width direction and a plurality of vertical supports 12 fixedly connected between the two horizontal supports 11. The plurality of vertical supports 12 are spaced apart along the length direction and are located between the two barrier members 2. The horizontal supports 11 are provided with a plurality of pouring ports 4 along the length direction, and the pouring ports 4 penetrate the horizontal supports 11.

[0027] Furthermore, both the horizontal support 11 and the vertical support 12 can be made of square steel pipes. The use of square steel pipes in the horizontal and vertical supports 11 and 12 ensures that the wall frame 1 serves as the main load-bearing framework of the wall, guaranteeing the wall has the support strength to meet the construction requirements. Simultaneously, assembling the wall frame 1 using square steel pipes, thanks to their regular shape, allows for convenient high-precision drilling and marking using CNC or laser processing technology. This process not only significantly improves the assembly efficiency and forming accuracy of the wall frame 1 and the double-layered wall itself, but also facilitates accurate connections between walls, thus laying a solid foundation for the high-precision assembly of the entire building. Ultimately, this high-precision building structure also facilitates lean construction for interior decoration.

[0028] Furthermore, in order to facilitate the connection between the two novel hollow double-skin wall panels, the vertical support 12 is provided with a connecting part 5, and the novel hollow double-skin wall panel is provided with an assembly groove 6 at the connecting part 5, and the connecting part 5 is located in the assembly groove 6.

[0029] Furthermore, the connecting part 5 includes a plurality of connecting steel rings 51 fixedly distributed at intervals on the vertical support 12, the connecting steel rings 51 being U-shaped. When two novel hollow double-layer walls are connected, the connecting steel rings 51 corresponding to the positions of the two novel hollow double-layer walls are staggered and layered, and then connected by reinforcing bars passing through the corresponding connecting steel rings 51. Concrete is then poured to complete the assembly and connection of the two novel hollow double-layer walls. This effectively ensures that the connection strength of the two novel hollow double-layer walls meets the usage requirements when connected to each other.

[0030] Furthermore, the connecting steel ring 51 is provided with two spaced-apart connecting pieces 52, which are fixedly disposed on both sides of the vertical support 12 to fix the connecting steel ring 51 to the vertical support 12. The two connecting pieces 52 can be fixed to the vertical support 12 by welding or anchoring, and the connecting pieces 52 are fixedly connected to the connecting steel ring 51 by nuts.

[0031] Furthermore, the vertical support 12 is provided with a vertical support cavity 121, and the vertical support 12 is connected to the horizontal support 11. The pouring port 4 on the horizontal support 11 is connected to the vertical support cavity 121. Concrete can be poured into the horizontal support 11 through the pouring port 4 and flow into the vertical support cavity 121, further improving the supporting strength of the wall frame 1.

[0032] The working principle of this embodiment is as follows: This embodiment uses two barrier elements 2 on the wall frame 1 to form a filling cavity 3 between them. During the factory prefabrication of this double-skin wall, a wall skin layer 7 can be cast on the outside of the wall frame 1 and barrier elements 2 using a mold, thus forming wall skin layers 7 on both sides of the wall frame 1 in the thickness direction, with the filling cavity 3 remaining between the two wall skin layers 7. With this structure, the factory-prefabricated double-skin wall of this embodiment is significantly lighter than traditional prefabricated walls, facilitating handling and transportation, reducing the difficulty and cost of export transportation, and enabling the transportation of a larger number of walls under the same conditions. After the wall is transported to the construction site, construction workers can pour concrete or other insulation materials into the filling cavity 3 through the pouring port 4 according to local environmental requirements, forming a wall suitable for local conditions, which can then be directly used for building assembly. If the wall is used in a low-rise building where higher support strength is not required, clay or other insulation materials can be directly poured into the filling cavity 3 to improve the wall's insulation performance. If it is to be used in a high-rise building, concrete can be poured directly to ensure the required strength. The process is simple, widely applicable, and allows construction personnel to flexibly choose and adjust the design, helping to reduce overall construction costs and improve construction efficiency.

[0033] Example 2: like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that both the horizontal support 11 and the vertical support 12 can be made of lightweight steel components. In this embodiment, the wall frame 1 can also be formed using lightweight steel components. Lightweight steel components have a certain supporting strength while being lighter in weight. In building scenarios where high supporting strength is not required (such as low-rise buildings or bungalows), using a lightweight steel structure for the wall frame 1 can meet the requirements for wall supporting strength while further reducing the weight of the wall, facilitating transportation and reducing costs.

[0034] The connecting part 5 includes a first H-groove 53 disposed on the vertical support 12. When the two novel hollow double-skin walls are connected, the first H-groove 53s on the two novel hollow double-skin walls are correspondingly arranged, forming a connecting cavity 54 between the first H-groove 53s on the novel hollow double-skin walls. A second H-groove 55 is disposed in the connecting cavity 54. The second H-groove 55 is used to connect the corresponding two first H-groove 53s. After the two first H-groove 53s are connected by the second H-groove 55, the second H-groove 55 is then connected by fasteners, and grout is poured into the connecting cavity 54, thereby completing the connection of the two novel hollow double-skin walls. Preferably, the first H-groove 53 and the second H-groove 55 are both C-shaped, and the connecting cavity 54 is provided with two second H-groove 55s, which are used to connect the corresponding ends of the two first H-groove 53s respectively, so that the two first H-groove 53s and the two second H-groove 55s form a frame-shaped structure distribution, improving the connection stability of the two novel hollow double-skin walls.

[0035] Furthermore, the vertical support 12 and the first hamlet groove 53 are provided with connecting members 56. The connecting members 56 overlap the vertical support 12 and the first hamlet groove 53, and are fixedly connected to the vertical support 12 and the first hamlet groove 53 respectively by fasteners. Preferably, the connecting member 56 is strip-shaped.

[0036] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
