Description

Technical Field

[0001] This utility model relates to a prefabricated wall panel. Background Technology

[0002] Modern buildings typically feature frame structures with internal partitions using wall panels, which are non-load-bearing interior walls. Precast wall panels used for non-load-bearing interior partitions are also known as lightweight partition panels, a new type of energy-saving building material. They are lightweight, thin, easy to assemble and disassemble, and possess energy-saving and environmentally friendly characteristics, rapidly gaining a foothold in industrialized construction. Precast wall panels on the market utilize a variety of engineering materials and have diverse structures and construction methods. A common type is the sandwich precast wall panel, which has a polystyrene board and polyethylene foam board as an interlayer, providing excellent thermal insulation and making it an excellent energy-saving building material. It is also thin, and the core layer is made of lightweight materials, making installation convenient. A drawback is that to prevent separation between the panel and the core layer, a strong adhesive is generally used to bond them, achieving a peel strength of over 0.1 MPa. This adhesive can slowly release over long-term use. Lightweight partition boards also have another problem: their strength is relatively lower and their thickness is thinner. Pipeline grooves can easily affect the structural strength of the precast wall panels, while placing them on the surface of the precast wall panels can have a certain impact on aesthetics. Utility Model Content

[0003] In view of the problem of harmful substance release in precast wall panels made with adhesives, the purpose of this utility model is to provide a precast wall panel that is connected with concrete.

[0004] Therefore, the present invention provides a precast wall panel, comprising a panel layer and a core layer, wherein the panel layer is disposed on both sides of the precast wall panel, the core layer is disposed inside the precast wall panel, the core layer and the panel layer are connected by a concrete layer, and the present invention also includes a connecting structure, wherein the two ends of the connecting structure are respectively disposed in the concrete layers on both sides of the core layer, and the connecting structure passes through the core layer.

[0005] Furthermore, it also includes wire mesh, which is embedded in the concrete.

[0006] The connecting structure is a strip structure, and its two ends are connected to the wire mesh; or the connecting structure is an I-shaped structure, and the two ends of the connecting structure are horizontally arranged T-shaped heads, which pass through the mesh of the wire mesh.

[0007] Furthermore, the panel layer is a metal panel, and the panel layer is welded with a connector facing the concrete layer, the other end of the connector being connected to a steel wire; or the connector is a stud, and the head of the stud passes through the wire mesh.

[0008] Furthermore, the prefabricated wall panel is provided with a groove, and the grooves of adjacent prefabricated wall panels are arranged opposite each other. The two grooves arranged opposite each other can be combined to form a channel for accommodating conduits or drainage pipes.

[0009] Furthermore, the prefabricated wall panel is also provided with several through holes, the through holes being perpendicular to the groove, and one end of the through hole communicating with the groove, so that the conduit or drain pipe provided in the channel is connected to the through hole.

[0010] Furthermore, junction boxes are pre-embedded in the prefabricated wall panels at the corresponding wiring locations in the partition wall design. Reserved holes are set between the through holes of the junction boxes, allowing the pipelines to pass through the through holes of the junction boxes and then through the reserved holes to connect to the junction boxes.

[0011] Furthermore, the precast wall panel has a rectangular panel layer, the groove is provided on the long side of the panel layer, and a rigid protrusion structure is provided on the other side of the precast wall panel opposite to the groove, which is used to cooperate and fix with the groove of the adjacent precast wall panel in the longitudinal direction.

[0012] Furthermore, the relatively short sides of the panel layer are also provided with rigid protrusion structures, which are installed in conjunction with the mounting grooves corresponding to the structural columns to form a partition wall.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] (1) A precast wall panel of this utility model is constructed with a panel, a concrete layer and a core layer. In order to solve the problem of easy separation between the concrete layer and the core layer, a connector is used to connect the concrete layers on both sides of the core layer. In a specific embodiment of this utility model, a wire mesh structure is also used. The wire mesh structure can not only prevent the thin concrete layer from cracking, but also connect part of the connector to the wire mesh or use the method of increasing the end area and passing through the wire mesh to improve the crack prevention of the precast wall panel and solve the problem of easy separation.

[0015] (2) In a specific embodiment of this utility model, a groove is provided on the long side of the precast wall panel, and two precast wall panels with opposite grooves are combined to form a pipeline channel. This can avoid the loss of thin precast wall panels by grooving, and also avoid the excessive reserved space on one side of the wall panel, which would affect the strength of the thin precast wall panel on that side. Several through holes are set perpendicular to the groove. The use of concrete connection increases the self-weight of the precast wall panel to a certain extent. The through holes can offset the self-weight of the precast wall panel with concrete connection to a certain extent. On the other hand, by using the through holes and groove connection, the pipeline can be conveniently connected to the required design position. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Reference Figures 1 to 5 As shown, a prefabricated wall panel of this utility model has a rectangular structure, including a long side and a short side. When installing the prefabricated wall panel 3, the long side is generally set horizontally. Figure 2 The cross-section of the precast wall panel 3 shows its layers, which sequentially include a panel layer 301, a concrete layer 302, a core layer 303, and another concrete layer 302. The panel layer 301 is located on the outermost side of the precast wall panel 3 and can be a thin metal panel, such as aluminum or steel. The core layer 303 is generally located in the center. The core layer 303 can be made of various materials, such as polystyrene or polystyrene, with fire-resistant and heat-insulating materials being preferred. The concrete layer 302 can be made from cement, lime, silica sand, etc., using aerated concrete molding to form a lightweight, porous concrete layer 302. (Refer to...) Figure 5 As shown, the connecting structure 304 can adopt an I-shaped structure. Both ends of the connecting structure 304 are T-shaped heads with horizontally arranged studs, and have a larger surface area of ​​disc structure to increase the contact area with the concrete layer 302. The middle is a rod that passes through the core layer 303.

[0025] In the above embodiments, reference is made to Figure 2 As shown, it also includes a wire mesh 306, which is disposed within the concrete layer. (Refer to...) Figure 5As shown, the aforementioned connecting structure 304 can pass through the mesh of the wire mesh 306. The connecting structure 304 can also be a strip-shaped structure, with both ends connected to the wire mesh 306. The wire mesh 306 can prevent cracking of the concrete layer 302 and also enhance the strength of the concrete layer 302. Through the tensile force of the connecting structure 304, it can prevent the concrete layer 302 from separating from the core layer 303. Similarly, to improve the strength of the panel layer 301 and the concrete layer 302, the panel layer uses a metal panel and is welded with a connector 305 facing the concrete layer 302, the other end of which is connected to the wire mesh; or the connector 305 is a stud, and the head of the stud passes through the wire mesh 306.

[0026] Reference Figure 1 , Figure 2 and Figure 6 As shown, installing pipelines in prefabricated lightweight partition walls is generally inconvenient. An improved solution involves: a groove 310 on the longer side of the prefabricated wall panel 3; adjacent grooves 310 of the prefabricated wall panel 3 are arranged opposite each other, forming a channel to accommodate conduits or drainage pipes. The prefabricated wall panel 3 also has several through holes, perpendicular to the grooves 310, with one end of each through hole communicating with the groove, allowing conduits or drainage pipes in the channel to connect to the through holes. Junction boxes 308 are pre-embedded in the prefabricated wall panel 3 at the designed wiring locations corresponding to the partition wall 1, with reserved holes between the junction box 308 and the through holes. Figure 2 A wire can be installed in the junction box 308 shown. The wire passes through the through hole in the junction box and then through the reserved hole to connect to the junction box 308. (Refer to...) Figure 1 , Figure 2 and Figure 6 As shown, a structural column 2 is installed at a predetermined position in the partition wall 1. The structural column 2 can be a steel structural column or a concrete structural column. Holes can be drilled at the positions of the installation channels corresponding to the structural column 2 to allow pipes 307 to pass through. The structural column 2 has an installation groove 201 for installing precast wall panels 3. The shape of the installation groove 201 can be a trapezoidal groove, a rectangular groove, etc. The opposite short sides of the precast wall panels 3 are provided with rigid protruding structures 309, such as those formed by concrete casting. The rigid protruding structure 309 cooperates with the installation groove 201. One side of the opposite long side of the precast wall panel 3 is a groove 310, and the other side is provided with a rigid protruding structure 309. The precast wall panels 3 are installed horizontally, that is, the longer side is placed horizontally. From bottom to top, the grooves 310 and rigid protruding structures 309 are used to cooperate in the installation. At the positions designed for installing pipelines or conduits 307, refer to Figure 6As shown, adjacent precast wall panels 3 are arranged with grooves 310 to grooves 310. Stepped surfaces can be provided on both sides of the grooves 310. After the lower precast wall panel 3 is installed, adhesive is applied to the grooves 310 and the upper surface of the precast wall panel 3. A pipe 307 is then inserted, and adhesive is filled above the pipe 307. The upper precast wall panel 3 is then placed on top of the lower precast wall panel 3 and compacted. The stepped surfaces are filled and connected with adhesive. Magnesium oxychloride cement can be used as the adhesive, which not only provides a sealing effect but also enhances the strength and durability of the connection, compensating for the lack of a rigid protruding structure to cooperate with the grooves 310. The precast wall panels 3 are then installed upwards using a rigid protruding structure to cooperate with the grooves 310, forming the required partition wall 1.
