Description

Technical Field

[0001] This utility model relates to the field of building decoration, and in particular to a prefabricated wall panel system. Background Technology

[0002] With the rapid development of industrialized construction, prefabricated decoration has been widely used due to its advantages such as quick construction, environmental protection and energy saving, and controllable quality. Among them, prefabricated wall panel systems are an important component of prefabricated decoration.

[0003] In existing prefabricated wall panel structures, a common connection method is to directly fix multiple decorative wall panels to the keel behind them with adhesive. While this method offers some convenience, it also has significant drawbacks: the connection strength depends entirely on the performance of the adhesive. In long-term use, relying solely on adhesive for connection can easily lead to cracking at the joints, warping or detachment of the decorative wall panels due to adhesive aging, changes in environmental temperature and humidity, or slight structural deformation, thus affecting the long-term stability of the structure.

[0004] Another connection method is to directly drive screws into the surface of the decorative wall panel, such as authorized notice number CN213014806U, or to add exposed screws on top of adhesive bonding. However, this approach will damage the integrity and aesthetics of the decorative wall panel surface, as the screws are exposed, affecting the decorative effect. Even after post-treatment, it is difficult to completely eliminate the damage to the overall aesthetics of the decorative surface, forming a noticeable "patchwork" effect. This is unacceptable in occasions requiring high aesthetics, such as high-end residences, office buildings, and hotels.

[0005] Therefore, there is an urgent need in this field for a prefabricated wall panel system that can simultaneously ensure a smooth and aesthetically pleasing surface and a long-lasting and secure connection. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this application is to provide a prefabricated wall panel system that can simultaneously achieve a smooth and aesthetically pleasing surface and a long-lasting and secure connection.

[0007] A prefabricated wall panel system includes a keel, a first decorative wall panel and a second decorative wall panel, each having its back side connected to the keel via an adhesive layer. The first decorative wall panel has a slot on its side facing the second decorative wall panel, and the second decorative wall panel has an insertion part inserted into the slot on its side facing the first decorative wall panel. The slot wall is also connected to a reinforcement member connected to the keel, and the reinforcement member is disposed between the back side of the insertion part and the keel.

[0008] Preferably, the reinforcement includes a groove wall connecting part, a keel connecting part for connecting with the keel, and an intermediate part connecting the groove wall connecting part and the keel connecting part.

[0009] Preferably, the middle portion is further connected to a plug portion that is laterally inserted into the second decorative wall panel on the other side opposite to the groove wall connection portion.

[0010] Preferably, the keel connecting part is fixedly connected to the keel by a self-tapping screw, and the plug part is also provided with a clearance hole to accommodate the self-tapping screw.

[0011] Preferably, the insertion part has a transition connection surface that transitions to connect with the groove wall connection part.

[0012] Preferably, the transition connection surface is either an arc surface or an inclined surface.

[0013] Preferably, the groove wall connecting part is connected to the groove wall of the slot by an adhesive layer.

[0014] Preferably, the lengths of the first decorative wall panel and the second decorative wall panel are both 0.5m to 1m and are equal, and the number of the reinforcing parts is one, with the reinforcing parts located at the middle position in the length direction of the slot.

[0015] Preferably, both the first decorative wall panel and the second decorative wall panel are provided with weight-reducing holes, which are round holes.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The prefabricated wall panel system of this utility model forms a composite connection mechanism of "adhesive bonding as the main method and mechanical reinforcement as a supplement," which greatly improves the safety and service life of the system and achieves long-term firmness. At the same time, the plug-in structure formed by the cooperation between the plug part and the slot also restricts the displacement of the two wall panels in the direction perpendicular to the wall surface, further enhancing the overall stability of the system. In addition, the reinforcement is set between the back of the plug part and the keel, which is cleverly hidden behind the plug part, so that there are no exposed fasteners on the front of the wall panel that will damage the decorative effect. At the same time, the precise cooperation between the plug part and the slot ensures the flatness and continuity of the joint, ultimately presenting a complete, clean and beautiful wall surface effect.

[0018] 2: The prefabricated wall panel system of this utility model has a plug-in part for the reinforcement to be inserted laterally into the second decorative wall panel, so that the reinforcement simultaneously restricts the displacement of the two wall panels in the direction perpendicular to the wall surface, further enhancing the overall stability of the system.

[0019] 3: In the prefabricated wall panel system of this utility model, the plug-in part has a transition connection surface that transitions with the groove wall connection part. The advantage of setting the transition connection surface is that when the plug-in part on the second decorative wall panel is inserted into the slot of the first decorative wall panel, the more appropriate operation method is generally to place the plug-in part on the groove wall connection part of the reinforcement and push it in smoothly. However, with the existence of the transition connection surface, even if the plug-in part accidentally touches the plug-in part, it can still be pushed into the slot smoothly, which is beneficial for the insertion between the two wall panels.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example:

[0027] A prefabricated wall panel system, such as Figure 1 As shown, it includes a keel 1, a first decorative wall panel 2, and a second decorative wall panel 3. The keel 1 is a light steel keel that is fixedly connected to the building wall.

[0028] The backs of the first decorative wall panel 2 and the second decorative wall panel 3 are both bonded and fixed to the keel 1 by a fully covered adhesive layer 4, which realizes the initial connection and force transmission. The adhesive layer 4 is specifically an epoxy resin adhesive layer.

[0029] On the side of the first decorative wall panel 2 facing the second decorative wall panel 3, a slot 21 is provided. The slot 21 extends along the length of the side and extends to both ends of the first decorative wall panel 2. Correspondingly, on the side of the second decorative wall panel 3 facing the first decorative wall panel 2, an insert part 31 is integrally formed and inserted into the slot 21. The mutual cooperation between the insert part 31 and the slot 21 realizes the precise alignment and tight splicing between the two wall panels.

[0030] The slot wall of the slot 21 is also connected to a reinforcement member 5 that connects to the keel 1. Structurally, the reinforcement member 5 includes a slot wall connecting part 51, a keel connecting part 52 for connecting to the keel 1, and a middle part 53 connecting the slot wall connecting part 51 and the keel connecting part 52. The keel connecting part 52 is fixedly connected to the keel 1 by a self-tapping screw 6. Positionally, the reinforcement member 5 is located between the back of the insertion part 31 and the keel 1. Thus, the insertion part 31 completely conceals and covers the reinforcement member 5 and the self-tapping screw 6 from the front. When viewed from the front of the wall panel, only a straight, thin seam is visible, with no trace of any mechanical fasteners. Generally, considering that the slot width of the slot 21 is not very large, an adhesive layer is used to connect the slot wall connecting part 51 and the slot wall of the slot 21 to facilitate the connection between the reinforcement member 5 and the slot 21.

[0031] The aforementioned prefabricated wall panel system has the following advantages:

[0032] ① Smooth and beautiful surface: Since the reinforcing parts 5 and their connecting screws 51 are cleverly hidden behind the insert part 31, there are no exposed fasteners on the front of the wall panel that would damage the decorative effect. At the same time, the precise fit between the insert part 31 and the slot 21 ensures the smoothness and continuity of the joint, ultimately presenting a complete, clean and beautiful wall effect.

[0033] ② Long-lasting and secure connection: This system forms a composite connection mechanism of "adhesive bonding as the main method and mechanical reinforcement as a supplement." The adhesive layer 4 provides a large area of ​​initial bonding force and uniform stress distribution, while the hidden reinforcement 5 provides reliable mechanical protection. Even if the adhesive ages to a certain extent in the future, the reinforcement 5 can still effectively prevent the wall panel from falling off, which greatly improves the safety and service life of the system and achieves long-lasting and secure connection. At the same time, the plug-in structure formed by the insertion part 31 and the slot 21 also restricts the displacement of the two wall panels in the direction perpendicular to the wall surface, further enhancing the overall stability of the system.

[0034] In this embodiment, the lengths of the first decorative wall panel 2 and the second decorative wall panel 3 are 0.5m-1m and are equal. The number of reinforcement parts 5 is one, and the reinforcement part 5 is located in the middle position of the length direction of the slot 21. The reasonable length and the appropriate number of reinforcement parts 5 can appropriately reduce the installation workload of the first decorative wall panel 2.

[0035] In this embodiment, both the first decorative wall panel 2 and the second decorative wall panel 3 are provided with weight-reducing holes 7. The weight-reducing holes 7 are round holes with a hollow design to reduce the density and weight of the wall panels. At the same time, drawing on the mechanical principles of arched bridges in ancient architecture, the compressive strength of the wall panels is prevented from decreasing too much when the wall panels lose some material due to the presence of weight-reducing holes 7. The diameter of the weight-reducing holes 7 can be determined in advance through experiments.

[0036] In a further embodiment, such as Figure 2-3 As shown, the middle part 53 is also connected to a plug-in part 54 on the other side of the groove wall connection part 51, which is laterally inserted into the second decorative wall panel 3. In effect, the reinforcement part 5 restricts the displacement of the two wall panels in the direction perpendicular to the wall surface, further enhancing the overall stability of the system. Of course, in order to facilitate the tightening of the self-tapping screw 6, the plug-in part 54 is also provided with a clearance hole 540 for the self-tapping screw 6.

[0037] In a further embodiment, such as Figure 4-5 As shown, the insertion part 54 has a transition connection surface 541 that transitions to the groove wall connection part 51. The transition connection surface 541 is either an arc surface or a slope surface. The advantage of providing the transition connection surface 541 is that when the insertion part 31 on the second decorative wall panel 3 is inserted into the slot 21 of the first decorative wall panel 2, the more suitable operation is generally to place the insertion part 31 on the groove wall connection part 51 of the reinforcement part 5 and push it in smoothly. However, with the presence of the transition connection surface 541, even if the insertion part 31 accidentally touches the insertion part 54, it can still be pushed into the slot 21 smoothly, which is beneficial for the insertion between the two wall panels.

[0038] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
