Description

Technical Field

[0001] This utility model relates to the field of building panel technology, specifically to an embedded and externally mounted prefabricated wall panel. Background Technology

[0002] Exterior wall panels are decorative wall panels installed on the exterior walls of buildings. They are typically used to enhance the aesthetics of buildings, increase thermal insulation, and provide waterproofing and fireproofing. They are a type of prefabricated building exterior structure and are non-load-bearing, therefore not contributing to the overall structural load. Due to their advantages of fast construction and good results, they are widely used in the construction industry.

[0003] Currently, common exterior wall panels include ordinary concrete wall panels, sandwich insulated wall panels, solid wood exterior wall panels, or metal exterior wall panels. These are typically dry-hanging construction methods where a framework is pre-installed on the wall, and then the corresponding wall panels are installed and positioned onto the framework. While these dry-hanging methods offer advantages such as structural stability and strong earthquake resistance, they also have drawbacks such as long construction periods, large space requirements, and high construction standards. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides an embedded and externally mounted prefabricated wall panel.

[0005] The present invention adopts the following technical solution: An embedded and external prefabricated wall panel includes: An external mounting frame is used to be installed on the bottom edge of a wall, and the external mounting frame has a supporting recess protrusion. Multiple prefabricated wall panels are provided. Each prefabricated wall panel has a flange and a locking protrusion on its top. The flange is used to screw onto the wall. Each prefabricated wall panel has a groove on its bottom. The multiple prefabricated wall panels are connected end to end in sequence, so that the locking protrusion of the next prefabricated wall panel engages with the groove of the previous prefabricated wall panel. The groove of the bottommost prefabricated wall panel engages with the supporting locking protrusion.

[0006] In one embodiment, a plurality of expansion screw fasteners are also included; The external mounting base also has a protruding base flange, and both the base flange and the plate flange are fixedly connected to the wall by multiple expansion screws.

[0007] In one embodiment, a U-shaped structural cover is also included, which covers the end of the base flange or the plate flange.

[0008] In one embodiment, the structural covering is a metal component.

[0009] In one embodiment, a sealing plug is also included; An air-proof through hole is formed between two adjacent precast wall panels and between the bottommost precast wall panel and the external mounting frame. The sealing plug is used to seal the openings at both ends of the air-proof through hole.

[0010] In one embodiment, the external mounting frame is made of aluminum alloy or engineering plastic.

[0011] In one embodiment, a rain shelter cover is also included; the topmost prefabricated wall panel is provided with a plurality of connecting pins at intervals, and the rain shelter cover is inserted into the topmost prefabricated wall panel through the plurality of connecting pins.

[0012] The beneficial effects of this utility model are as follows: By installing an external mounting frame along the bottom edge of the wall, structural support can be provided for multiple prefabricated wall panels connected end-to-end. During installation, simply engage the groove of the bottom prefabricated wall panel with the support protrusion of the external mounting frame, then fix its top flange to the wall. The remaining prefabricated wall panels are then stacked and secured by engaging them end-to-end. In practice, the protrusion of the next prefabricated wall panel can be directly slid into the groove of the previous panel from the side, resulting in a simple and efficient installation. This invention overcomes the shortcomings of existing dry-hanging construction methods using a keel frame, offering significant advantages such as short construction period, small space occupation, and low construction difficulty.

[0015] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0016] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the instruction manual appendix as well. Figure 1-5 As shown, this utility model discloses an embedded and externally mounted assembled wall panel, comprising an external mounting frame 1 and multiple prefabricated wall panels 2. The external mounting frame 1 is used to be installed on the bottom edge of the wall, and the external mounting frame 1 has a supporting protrusion 11 protruding from it. Each prefabricated wall panel 2 has a plate flange 21 and a plate locking protrusion 22 protruding from its top. The plate flange 21 is used to be screwed to the wall. Each prefabricated wall panel 2 has a plate groove 23 at its bottom. Multiple prefabricated wall panels 2 are connected end to end in sequence, so that the plate locking protrusion 22 of the next prefabricated wall panel 2 is engaged in the plate groove 23 of the previous prefabricated wall panel 2. The plate groove 23 of the bottommost prefabricated wall panel 2 is engaged with the supporting protrusion 11.

[0018] In this embodiment, by installing an external hanging frame 1 at the bottom edge of the wall, structural support can be provided for multiple prefabricated wall panels 2 connected end to end above. During installation, it is only necessary to engage the panel groove 23 of the bottommost prefabricated wall panel 2 with the support protrusion 11 of the external hanging frame 1, and then fix the top panel flange 21 to the wall. Then, the remaining prefabricated wall panels 2 are stacked and fixed by engaging them end to end. In actual operation, the panel protrusion 22 of the next prefabricated wall panel 2 can be directly slid into the panel groove 23 of the previous prefabricated wall panel 2 from the side to achieve engagement. The installation operation is simple and efficient. This utility model can overcome the shortcomings of the existing dry-hanging construction method using a keel frame, and has obvious advantages such as short construction period, small space occupation, and low construction difficulty.

[0019] like Figures 1 to 4As shown, preferably, an embedded external mounting wall panel further includes multiple expansion screw fasteners 3; the external mounting base 1 also has a protruding base flange 12, and both the base flange 12 and the panel flange 21 are fixedly connected to the wall by multiple expansion screw fasteners 3. It can be understood that by using multiple expansion screw fasteners 3 arranged sequentially and spaced along the length direction of the base flange 12 and the panel flange 21, the expansion screw fasteners 3 are pre-driven into the wall for fixation, so that the protruding threaded ends pass through the corresponding base flange 12 or panel flange 21. Then, nuts are tightened onto the threaded ends of the expansion screw fasteners 3 to secure the base flange 12 and the panel flange 21 to the outer edge of the wall. This method occupies little space, is simple and reliable, and is easy to operate.

[0020] like Figures 2 to 4 As shown, preferably, an embedded and externally mounted prefabricated wall panel further includes a U-shaped structural covering 4, which covers the end of the base frame flange 12 or the plate flange 21. It can be understood that in this embodiment, the prefabricated wall panel 2 has a sandwich structure. The outer layer is mainly made of aluminum plate or polymer board, providing certain strength support and serving a decorative function. The inner layer is filled with polyurethane foam (PU / PIR), rock wool, or mineral wool for insulation and lightweighting. A structural steel mesh is also provided in the inner layer to provide structural strength and stability support. Thus, the use of a metal structural covering 4 to cover the end of the base frame flange 12 or the plate flange 21 further improves the structural strength of the ends of the base frame flange 12 and the plate flange 21. This avoids the problem of compression deformation or even damage to the base frame flange 12 or the plate flange 21 when the nut is tightened onto the threaded end of the expansion screw fastener 3, thereby ensuring better stability of the external base frame 1 and the prefabricated wall panel 2 fixed to the wall.

[0021] like Figures 1 to 5 As shown, preferably, an embedded and externally mounted prefabricated wall panel further includes a sealing plug 5; a clearance hole 24 is formed between two adjacent prefabricated wall panels 2, and between the bottom prefabricated wall panel 2 and the external mounting frame 1, and the sealing plug 5 is used to seal the openings at both ends of the clearance hole 24. It can be understood that the threaded end of the assembled expansion screw fastener 3 will extend into the clearance hole 24. To prevent excessive erosion of the threaded end of the expansion screw fastener 3 and the nut by rainwater, the sealing plug 5 is used to seal the openings at both ends of the clearance hole 24. Specifically, the sealing plug 5 is interference-fitted with the opening of the clearance hole 24. Similarly, a clearance hole 24 is also formed between the bottom prefabricated wall panel 2 and the external mounting frame 1, and the opening of the clearance hole 24 here is also sealed with a sealing plug 5 for waterproofing.

[0022] like Figure 1 As shown, preferably, the external mounting frame 1 is made of aluminum alloy or engineering plastic.

[0023] like Figure 1 and Figure 5 As shown, preferably, an embedded and externally mounted prefabricated wall panel also includes a rainproof cover 6; the topmost prefabricated wall panel 2 is provided with a plurality of connecting pins 25 at intervals, and the rainproof cover 6 is inserted into the topmost prefabricated wall panel 2 through the plurality of connecting pins 25. It can be understood that, in this embodiment, the rainproof cover 6 is provided with positioning holes corresponding to the connecting pins 25. During installation, the positioning holes of the rainproof cover 6 are directly aligned with the connecting pins 25 and inserted, and the installation of the rainproof cover 6 is completed by utilizing the interference fit formed between the connecting pins 25 and the positioning holes. Further, in one embodiment, a clearance hole 24 is also formed between the topmost prefabricated wall panel 2 and the rainproof cover 6, and the connecting pins 25 are provided in the clearance hole 24. The opening of the clearance hole 24 is also sealed and waterproofed by a sealing plug 5.

[0024] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
