Description

Technical Field

[0001] This utility model relates to a wall panel structure, specifically a self-locking modular composite wall panel structure, belonging to the field of wall panel structure technology. Background Technology

[0002] As the core space for product display and brand promotion, the exhibition hall is characterized by its temporary nature, high frequency of updates, and personalization. In such scenarios, the "efficiency" and "effectiveness" of structural construction become the core requirements. Therefore, modular composite wall panel structures are needed to package the exhibition hall during construction.

[0003] However, most existing wall panel structures have various problems. For example, in a composite wall panel disclosed in publication number CN108104364A, although it solves the problem of the heavy weight of traditional bricks, in this technical solution and most current composite wall panel structures, traditional exhibition hall construction has long relied on the rigid connection method of welding and nailing. Its technical logic comes from the "fixed construction" thinking of early industrial buildings. Welding is used to achieve rigid splicing of metal components, and nailing is used to fix the panels and the frame to ensure the stability of the basic structure. This method has long been the mainstream choice for exhibition hall construction because of its mature technology and low initial equipment investment. As the exhibition industry upgrades its demands for "efficiency, low cost, and high quality," the inherent defects of welding and nailing methods have gradually become apparent, making them unsuitable for current scenarios. The exhibition industry is currently developing towards "fast assembly and disassembly, recycling, green environmental protection, and quality upgrades." However, the traditional construction methods of welding and nailing cannot meet the "fast-paced" requirements of exhibitions, and their high cost and high waste contradict the industry trend of "green and low-carbon." Furthermore, they are difficult to adapt to the aesthetic and stability requirements of high-end exhibition halls. This contradiction between technology and demand has led to the exhibition construction industry facing a long-term dilemma of "low efficiency, high cost, and poor quality." Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a self-locking modular composite wall panel structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A self-locking modular composite wall panel structure includes a composite wall panel body and connecting components. The composite wall panel body has a rectangular structure and constitutes the main structure of the modular composite wall panel structure. The connecting components are symmetrically arranged on both sides of the composite wall panel body. The connecting assembly includes a first connecting plate, a second connecting plate, a first mounting hole, and a second mounting hole. The first connecting plate is fixed to one side of the composite wall panel body and is recessed into the interior of the composite wall panel body. The second connecting plate is fixed to the other side of the composite wall panel body and is protruding outward from the composite wall panel body. Both the first connecting plate and the second connecting plate have an arch-shaped structure, and the first connecting plate and the second connecting plate between two adjacent composite wall panel bodies are nested and connected to each other. The connecting assembly further includes a first mounting hole, a second mounting hole, and a self-locking screw. The first mounting hole is disposed through the first connecting plate, the second mounting hole is disposed through the second connecting plate, and the self-locking screw passes through the first mounting hole and the second mounting hole and is locked between the first connecting plate and the second connecting plate.

[0006] As a further embodiment of this utility model: the connecting assembly further includes a self-locking block and a nut. The self-locking block is disposed on the peripheral wall of one end of the self-locking screw and abuts against the first connecting plate. The diameter of the overall structure formed by the combination of the self-locking block and the self-locking screw is larger than the mounting hole. The nut is screwed onto the other end of the self-locking screw and abuts against the second connecting plate.

[0007] As a further improvement of this utility model: a gasket is provided on the side of the first connecting plate near the self-locking block, and the gasket is sleeved on the outside of the self-locking screw.

[0008] As a further embodiment of this utility model: both ends of the first connecting plate and the second connecting plate are vertically fixed with snap-fit ​​plates, and together with the snap-fit ​​plates, they form an inverted U-shaped structure. Both ends of the composite wall panel body are provided with inverted U-shaped slots, and the first connecting plate and the second connecting plate are snapped into the inverted U-shaped slots in cooperation with the snap-fit ​​plates.

[0009] As a further improvement of this utility model, at least two nuts are screwed onto the self-locking screw.

[0010] As a further improvement of this utility model, at least two sets of self-locking screw structures are provided between the first connecting plate and the second connecting plate.

[0011] The beneficial effects of this utility model are: In this utility model, a first connecting plate and a second connecting plate are symmetrically arranged on both sides of the composite wall panel body. They adopt an arch-shaped concave-convex nested structure. During installation, the protruding second connecting plate is simply inserted into the recessed first connecting plate to achieve automatic positioning. This design eliminates the positioning and calibration process required by traditional welding and nailing methods, significantly shortening the time for connecting a single wall panel and greatly reducing the exhibition hall construction cycle, thus meeting the needs of rapid installation for exhibitions. The connection is achieved by a self-locking screw passing through the first and second mounting holes, replacing traditional welding and nailing. During installation, only the nut needs to be turned to lock the panel. No professional welders or complex tools are required, and ordinary workers can operate the system, reducing labor costs. At the same time, the combination of the self-locking block and the nut achieves a "reversible connection." When disassembling, the wall panel can be separated simply by unscrewing the nut, avoiding the cutting and damage of traditional welded components. The nesting of the bow-shaped connecting plates, combined with the axial tension of the self-locking screw, forms a three-dimensional constraint structure, which significantly improves the resistance to lateral forces compared to traditional welding. This avoids problems such as weld cracking and loose nails caused by external impacts. At the same time, the gaskets ensure that the connecting plates fit tightly, meeting the stringent appearance requirements of high-end showrooms. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 4As shown, a self-locking modular composite wall panel structure includes a composite wall panel body 1 and connecting components. The composite wall panel body 1 has a rectangular structure and constitutes the main structure of the modular composite wall panel structure. The connecting components are symmetrically arranged on both sides of the composite wall panel body 1. The connecting assembly includes a first connecting plate 2, a second connecting plate 3, a first mounting hole 4, and a second mounting hole 5. The first connecting plate 2 is fixed to one side of the composite wall panel body 1 and is recessed towards the inside of the composite wall panel body 1. The second connecting plate 3 is fixed to the other side of the composite wall panel body 1 and is protruding towards the outside of the composite wall panel body 1. Both the first connecting plate 2 and the second connecting plate 3 have an arch-shaped structure, and the first connecting plate 2 and the second connecting plate 3 between two adjacent composite wall panel bodies 1 are nested and connected to each other. The connecting assembly also includes a first mounting hole 4, a second mounting hole 5, and a self-locking screw 6. The first mounting hole 4 is disposed through the first connecting plate 2, the second mounting hole 5 is disposed through the second connecting plate 3, and the self-locking screw 6 passes through the first mounting hole 4 and the second mounting hole 5 and is locked between the first connecting plate 2 and the second connecting plate 3. The connecting assembly also includes a self-locking block 7 and a nut 8. The self-locking block 7 is disposed on the peripheral wall of one end of the self-locking screw 6 and abuts against the first connecting plate 2. The diameter of the overall structure formed by the combination of the self-locking block 7 and the self-locking screw 6 is larger than the mounting hole. The nut 8 is screwed to the other end of the self-locking screw 6 and abuts against the second connecting plate 3. A washer 9 is provided on the side of the first connecting plate 2 near the self-locking block 7. The washer 9 is sleeved on the outside of the self-locking screw 6.

[0016] In this utility model, the first connecting plate 2 and the second connecting plate 3 are symmetrically arranged on both sides of the composite wall panel body 1, and adopt an arch-shaped concave-convex nested structure. During installation, the protruding second connecting plate 3 is simply inserted into the recessed first connecting plate 2 to achieve automatic positioning. This design eliminates the positioning and calibration process in traditional welding and nailing methods, greatly shortening the time for connecting a single wall panel and significantly reducing the exhibition hall construction cycle, thus meeting the needs of rapid installation for exhibitions. The connection is achieved by the self-locking screw 6 passing through the first mounting hole 4 and the second mounting hole 5, replacing traditional welding and nailing. During installation, only the nut 8 needs to be turned to lock it, eliminating the need for professional welders or complex tools. Ordinary workers can operate it, reducing labor costs. At the same time, the combination of the self-locking block 7 and the nut 8 achieves a "reversible connection". When disassembling, only the nut 8 needs to be unscrewed to separate the wall panel, avoiding the cutting and loss of traditional welded components. The nesting of the bow-shaped connecting plates, combined with the axial tension of the self-locking screw 6, forms a three-dimensional constraint structure, which significantly improves the resistance to lateral forces compared to traditional welding. This avoids problems such as weld cracking and loose nails caused by external impacts. At the same time, the setting of the gasket 9 ensures that the connecting plates fit tightly, meeting the stringent appearance requirements of high-end showrooms. Example 2

[0017] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: Both ends of the first connecting plate 2 and the second connecting plate 3 are vertically fixed with snap-fit ​​plates 10, which together form a U-shaped structure. The two ends of the composite wall panel body 1 are provided with U-shaped grooves. The first connecting plate 2 and the second connecting plate 3 are engaged with the snap-fit ​​plates 10 in the U-shaped grooves to form a "three-dimensional snap-fit ​​structure". During installation, the snap-fit ​​plates 10 can be directly embedded into the U-shaped grooves at both ends of the composite wall panel body 1. This not only achieves precise positioning of the connecting plate and the wall panel body, but also transforms the axial force of the traditional single-point screw connection into surface contact force through the engagement of the grooves and the snap-fit ​​plates 10. This improves the connection strength between the connecting plate and the wall panel body and effectively prevents the connecting plate from lateral displacement or falling off under stress. It is especially suitable for ensuring structural stability in high-frequency handling scenarios in exhibition halls.

[0018] Nut 8 is screwed onto the self-locking screw 6 at least twice. By utilizing the interlocking principle of the double nuts, the vibration resistance and loosening performance of the connection structure are improved. This design can ensure that the wall panel remains firmly connected throughout the entire extension period, avoid the risk of wall panel falling off due to loose nuts, reduce the workload of extension period maintenance, and reduce the probability of sudden safety accidents.

[0019] At least two sets of self-locking screws 6 are provided between the first connecting plate 2 and the second connecting plate 3, which transforms single-point force into multi-point balanced bearing. The shear strength of the two sets of screws is significantly improved compared to a single set, thereby improving the overall structural strength of the wall panel structure.

[0020] Working principle: When using this wall panel structure, first pass the self-locking screw 6 through the washer 9 and the first mounting hole 4 in sequence. Then, align the second connecting plate 3 of the adjacent wall panel with the first connecting plate 2 of the other wall panel along the design axis. Push the wall panel to make the bow-shaped structure of the two wall panels nest and connect. At the same time, ensure that the snap-fit ​​plate 10 is fully embedded in the corresponding slot to complete the planar positioning. At this time, the self-locking screw 6 is inserted into the aligned hole of the first mounting hole 4 and the second mounting hole 5, so that the screw passes through the two connecting plates in sequence. At this time, the self-locking snap-fit ​​block 7 is pressed against the inner side of the first connecting plate 2, and the washer 9 is attached to the surface of the connecting plate. Tighten at least two nuts 8 at the other end of the screw to lock it through the double nut interlocking principle.
