Description

Technical Field

[0001] This utility model relates to the field of building exterior wall materials technology, and in particular to a spliced, ventilated exterior wall panel. Background Technology

[0002] Exterior wall panels are the external enclosure structure of a building. Their main functions are to provide protection, decoration, and a certain degree of thermal insulation for the building. With the development of the construction industry and the improvement of environmental awareness, the function of exterior wall panels, as an important part of the building's external enclosure structure, is no longer limited to simple decoration and thermal insulation. Modern buildings have put forward higher requirements for exterior wall panels, including ventilation performance, ease of installation, structural stability, energy saving and environmental protection.

[0003] Currently, exterior wall panels are typically assembled to form a complete external envelope structure in practical applications. However, existing assembly methods mostly rely on structural adhesives for bonding. While this method is simple to operate, it has the following significant drawbacks: 1. The bonding strength of structural adhesives is easily affected by external forces, temperature changes, and humidity fluctuations, leading to loosening or even cracking at the joints. 2. Over time, the aging of the structural adhesives can cause the joints to gradually separate, which not only reduces the performance of the exterior wall panels but may also pose safety hazards. 3. Assembly methods relying on structural adhesives require a long curing time and have high requirements for the construction environment, increasing construction difficulty and cost.

[0004] To address these issues, the market urgently needs a modular, permeable exterior wall panel to meet the diverse requirements of modern architecture for functionality, safety, and construction efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of existing exterior wall panels that rely on structural adhesive for bonding and assembly, such as poor connection reliability, susceptibility to environmental factors, and high construction difficulty and cost, this utility model provides a spliced, ventilated exterior wall panel.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a splicing, ventilated exterior wall panel, comprising a convex exterior wall panel and a concave exterior wall panel. The bottom of the convex exterior wall panel and the top of the concave exterior wall panel are vertically spliced ​​together through an interlocking design. Furthermore, both the convex and concave exterior wall panels are made of ventilated material. Mounting grooves are provided on both sides of the back of both the convex and concave exterior wall panels. Each mounting groove contains a semi-circular slot, into which a pin is inserted. The pin has protruding structures on both sides, which can be embedded within the semi-circular slot. An X-shaped reinforcing rod is provided on the pin, with fixing rods connected to the four ends of the X-shaped reinforcing rod. The mounting groove has locking holes at its two corners that match the fixing rods.

[0007] More preferably, the bottom of the convex exterior wall panel is provided with a cylindrical insert, the top of the concave exterior wall panel is provided with a groove that matches the cylindrical insert, and slots are provided on both sides of the groove. Both sides of the cylindrical insert are slidably provided with locking blocks that match the slots, and an elastic element connects the locking blocks and the cylindrical insert.

[0008] More preferably, the concave exterior wall panel is provided with a water-blocking strip at the top, the convex exterior wall panel is slidably provided with a guide rod on one side of the bottom, a pressure plate is fixedly connected to the guide rod, and a screw is threadedly provided on the other side of the bottom of the convex exterior wall panel, the bottom end of the screw being rotatably connected to the pressure plate.

[0009] More preferably, mounting holes are provided on both sides of the upper part of the convex exterior wall panel and on both sides of the lower part of the concave exterior wall panel.

[0010] More preferably, threaded holes are provided at the four corner joints of the convex and concave exterior wall panels, and screws are installed inside the threaded holes.

[0011] More preferably, a filling groove is provided at the joint between the convex exterior wall panel and the concave exterior wall panel.

[0012] More preferably, sound insulation cotton is provided on the back of the convex and concave exterior wall panels.

[0013] Compared with the prior art, the present invention has the following technical effects: 1. The convex and concave exterior wall panels are spliced ​​vertically through the interlocking design, ensuring the stability of the upper and lower splices. The horizontal splicing strength is further enhanced by the design of X-shaped reinforcing rods and pins, effectively resisting the influence of external forces, vibrations or severe weather. In addition, all exterior wall panels and their components are prefabricated in the factory, and only need to be assembled on site in a modular manner, which greatly shortens the construction time, reduces labor costs, and ensures the consistency of installation quality.

[0014] 2. Through the interlocking design of the cylindrical insert and the groove, combined with the reset function of the locking block and the elastic element, a stable connection between the convex and concave exterior wall panels is achieved. This locking method significantly improves the stability of the upper and lower splicing.

[0015] 3. Install a water-blocking strip on the top of the concave exterior wall panel and use screws to drive the pressure plate to press and fix it, effectively sealing the splicing gaps, preventing rainwater from seeping into the interior of the wall, and enhancing the building's waterproofing ability.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1: Please refer to Figures 1-4A type of spliced, ventilated exterior wall panel includes a convex exterior wall panel 1 and a concave exterior wall panel 2. The bottom of the convex exterior wall panel 1 and the top of the concave exterior wall panel 2 are vertically spliced ​​together through an interlocking design. Furthermore, both the convex exterior wall panel 1 and the concave exterior wall panel 2 are made of breathable material to enhance the ventilation performance of the wall, reduce moisture accumulation, and lower the risk of mold and corrosion. The convex exterior wall panel 1 and the concave exterior wall panel 2 have mounting grooves on both the left and right sides of their back surfaces, and each mounting groove contains a... A semi-circular slot is provided, and a pin 3 is inserted into the semi-circular slot. The pin 3 has protruding structures 4 on both working sides. The protruding structures 4 can be embedded inside the semi-circular slot to strengthen the connection stability of the pin 3. An X-shaped reinforcing rod 5 is provided on the pin 3. The four ends of the X-shaped reinforcing rod 5 are respectively connected to fixing rods 7. The two corners inside the mounting groove are provided with locking holes 8 that match the fixing rods 7. The position of the X-shaped reinforcing rod 5 is further fixed by locking the fixing rods 7 into the locking holes 8.

[0027] First, all convex exterior wall panels 1, concave exterior wall panels 2, and their components are prefabricated in the factory for easy installation after transportation to the designated location. When installing the exterior wall panels, align the bottom of a convex exterior wall panel 1 with the top of a concave exterior wall panel 2, and complete the vertical splicing through the interlocking design. When performing horizontal splicing, first horizontally insert half of the X-shaped reinforcing rod 5 into the installation groove of one exterior wall panel, ensuring that half of the pin 3 slides into the corresponding semi-circular slot. At the same time, adjust the position so that the fixing rods 7 at both ends of the X-shaped reinforcing rod 5 are accurately inserted into the locking holes 8 in the installation groove, thereby initially fixing the X-shaped reinforcing rod 5. Next, horizontally align the other exterior wall panel to be spliced, insert the other half of the X-shaped reinforcing rod 5 into the installation groove of the exterior wall panel, and simultaneously allow the other half of the pin 3 to slide into the corresponding semi-circular slot. Finally, check whether the fixing rods 7 of the X-shaped reinforcing rod 5 are fully embedded in the locking holes 8 to ensure a stable connection between the two exterior wall panels in the horizontal direction.

[0028] Example 2: Based on Example 1, please refer to... Figure 4 The bottom of the convex outer wall panel 1 is provided with a cylindrical insert 9, and the top of the concave outer wall panel 2 is provided with a groove that matches the cylindrical insert 9. The groove is also provided with slots on the left and right sides. The cylindrical insert 9 is slidably provided with a locking block 10 that matches the slot on both the left and right sides. An elastic element 11 is connected between the locking block 10 and the cylindrical insert 9 to provide a reset elastic force for the locking block 10.

[0029] When the bottom of the convex exterior wall panel 1 is aligned and spliced ​​with the concave exterior wall panel 2, the cylindrical insert 9 is inserted into the groove. During this process, the inner wall of the groove applies lateral pressure to the locking block 10, causing the locking block 10 to slide into the cylindrical insert 9. At the same time, the elastic element 11 is compressed. As the cylindrical insert 9 gradually penetrates deeper into the groove, the locking block 10 is ejected outward under the reset action of the elastic element 11 and embedded in the pre-set slots on both sides of the groove, thereby achieving a stable connection between the convex exterior wall panel 1 and the concave exterior wall panel 2, significantly improving the stability of the upper and lower splicing.

[0030] Please see Figures 5-7 The concave exterior wall panel 2 is provided with a water-blocking strip 14 on the top to prevent rainwater from seeping into the splicing gap. A guide rod 15 is slidably provided on one side of the bottom of the convex exterior wall panel 1. A pressure plate 12 is fixedly connected to the guide rod 15 to press the water-blocking strip 14. A screw 13 is threaded on the other side of the bottom of the convex exterior wall panel 1. The bottom end of the screw 13 is rotatably connected to the pressure plate 12 to ensure that the screw 13 can drive the pressure plate 12 to move up and down when it rotates.

[0031] After the bottom of the convex exterior wall panel 1 and the concave exterior wall panel 2 are aligned and spliced, the screw 13 is rotated. The screw 13 drives the pressure plate 12 and the guide rod 15 fixed thereto to move downward together through the threaded transmission. The pressure plate 12 presses down on the water-blocking strip 14 on the top of the concave exterior wall panel 2 and fixes it in the preset position, thereby effectively blocking the splicing gap between the bottom of the convex exterior wall panel 1 and the concave exterior wall panel 2 and preventing rainwater from seeping in.

[0032] Please see Figure 1 and Figure 8 Mounting holes are provided on both sides of the upper part of the convex exterior wall panel 1 and on both sides of the lower part of the concave exterior wall panel 2. Bolts or other fasteners are passed through these mounting holes and connected to the wall, ensuring the exterior wall panel is firmly attached to the building surface and preventing it from falling off due to external forces or vibrations. Threaded holes are provided at the four corner joints of the convex exterior wall panel 1 and the concave exterior wall panel 2. Screws 16 are installed inside these threaded holes. Tightening the screws 16 further strengthens the connection at the joint, reducing loosening or deformation caused by external environmental factors, thereby improving the overall structural integrity. Stability; A filling groove 17 is provided at the joint between the convex exterior wall panel 1 and the concave exterior wall panel 2. By filling the filling groove 17 with adhesive, the connection strength at the joint is improved, and the joint gap is effectively sealed to prevent rainwater, dust and other external substances from seeping into the wall, thereby enhancing the waterproof performance and durability of the exterior wall panel; Sound insulation cotton 18 is provided on the back of the convex exterior wall panel 1 and the concave exterior wall panel 2, which is mainly used to improve the sound insulation effect of the building. The sound insulation cotton 18 can absorb sound wave energy, reduce noise transmission, and provide a quieter living or working environment indoors.
