Description

Technical Field

[0001] This utility model relates to the field of building formwork connection technology, specifically to a wall insulation connector. Background Technology

[0002] Traditional insulation boards rely on adhesives and anchors for fixation, which can easily lead to detachment due to gravity, temperature changes, or material aging after long-term use. In contrast, the design of wall insulation connectors enhances anchoring strength through mechanical structures, ensuring the insulation system has the same lifespan as the building.

[0003] Among existing products, L-shaped integrated snap-on insulation board connectors are L-shaped structures made of metal or FRP. One end is fixed to the wall with expansion bolts, and the other end is embedded in the L-shaped or square groove of the insulation board. Some models are equipped with self-locking spring clips. This type of connector achieves a rigid connection between the insulation board and the wall through a snap-on structure, resisting wind pressure and vibration. Its advantage is that it eliminates the need for complex binding or drilling, simplifying the construction process.

[0004] In practical applications, these types of connectors rely on friction or simple clips for fixation. However, under prolonged exposure to wind vibration or temperature differences, they inevitably loosen, leading to displacement of the insulation board. Therefore, it is necessary to propose a new type of wall insulation connector that improves connection stability and addresses the issue of loosening after extended use. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a wall insulation connector. Through the design of a slidingly adjustable box-shaped insulation support and a wedge-shaped self-locking structure, it solves the problems of displacement and loosening caused by vibration or temperature difference, as well as stress concentration, in traditional insulation connectors, achieving dynamic anchoring and long-term stability.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: it includes an L-shaped main plate, and one end of the main plate is provided with a wall-connecting groove assembly for connecting the wall and the main plate by expansion screws;

[0007] The main body panel has a fastening component at the end away from the wall-connecting groove, which is adjusted according to the thickness of different insulation boards. The fastening component is slidably connected to the main body panel. A connecting component is provided between the fastening component and the main body panel to reinforce the connection between the insulation board and the main body panel. The fastening component has symmetrical connecting plate grooves on its surface. The main body panel has connecting plate holes at the corresponding positions of the connecting plate grooves. The fastening component has symmetrical locking components, which are used to lock and fix the edge of the corresponding insulation board.

[0008] The technical principle of the above solution is as follows: In use, the main body plate of the insulation connector designed in this solution is first installed on the wall using expansion screws via the wall connection groove assembly. Then, according to the position of the insulation board, the fastening assembly is slid a corresponding distance on the main body plate, and the insulation board is secured by the locking assembly design. During this process, the connecting assembly allows for a stepped installation of the sliding distance. Finally, the fastening assembly and the insulation board are fixed to the main body plate through the connecting plate hole and connecting plate groove, thus completing the connection between the insulation board and the wall. During the insulation board's effective operation, the design of the connecting assembly increases the connection stability between the insulation board and the wall, i.e., increases the resistance to detachment in directions away from or near the wall, while the design of the locking assembly increases the resistance to detachment of the insulation board in a direction perpendicular to the main body plate.

[0009] The above approach has the following beneficial effects:

[0010] 1. Traditional connectors have fixed dimensions, which greatly limits their application when dealing with insulation boards of varying thicknesses. The fastening components in this solution feature a sliding adjustment function, enhancing compatibility with different insulation board thicknesses. During construction, workers can flexibly adjust the relative position of the fastening components to the main board according to the actual thickness of the insulation board.

[0011] 2. This solution, by combining the design of connecting components and fastening components, increases four-way stability perpendicular to and parallel to the wall surface, strengthens the connection between the insulation board and the wall, and ensures that the insulation board and the wall can be firmly fixed even under complex external force environments.

[0012] Furthermore, the wall-connecting groove assembly includes a central groove and several side grooves, which are located on both sides of the central groove and are perpendicular to the central groove.

[0013] Beneficial effects: The vertical arrangement of the side and center grooves enhances the fixing stability of expansion bolts compared to the single-groove design of traditional connectors. The vertical and horizontal arrangement of the grooves allows the force to be evenly distributed through the side and center grooves when the expansion bolts are under stress, preventing stress concentration and reducing pressure on localized walls.

[0014] Furthermore, the fastening assembly includes a fastening block, which is a box-shaped structure with one end open.

[0015] Beneficial effects: The box-shaped structure design of the interlocking blocks, with its three-dimensional enclosed frame, has stronger resistance to deformation than traditional sheet structures, effectively restraining the lateral displacement of the insulation board. When the insulation board is subjected to lateral force, all surfaces of the box-shaped structure will work together to resist and prevent the insulation board from moving.

[0016] Furthermore, the fastening block includes a first fastening plate and a second fastening plate that slide and engage with each other.

[0017] Beneficial effects: During construction, various factors may cause errors. The separate design of the first and second interlocking plates can compensate for these errors. Under stress, the first and second interlocking plates can share the pressure, avoiding excessive local stress and improving the adaptability of the insulation connectors.

[0018] Furthermore, the connecting component includes several wedge blocks and wedge grooves. The several wedge grooves are symmetrically opened at the bottom of the first fastening plate and the top of the second fastening plate, and the several wedge grooves are integrally fixedly connected to the surface of the main body plate corresponding to the position of the wedge blocks.

[0019] Beneficial effects: The planar contact design of the wedge block and wedge groove increases the friction between the first or second fastening plate and the main body plate, preventing the corresponding fastening plates from loosening or separating. When the insulation board is subjected to lateral force, a self-locking effect is generated between the wedge block and the wedge groove on the corresponding first or second fastening block connected to the insulation board, effectively dispersing the lateral force, reducing damage to the connectors and the insulation board, and ensuring the stability of the insulation system during long-term use.

[0020] Furthermore, all the locking components include U-shaped locking slots.

[0021] Beneficial effects: The U-shaped groove wraps tightly around the edge of the insulation board, securing it firmly to the wall.

[0022] Furthermore, inclined blocks are fixedly connected to both sides of the inner wall of the slot.

[0023] Beneficial effects: The parallel inclined surface layout of the inclined blocks within the slot effectively decomposes vertical separation forces. When the insulation board is subjected to a vertical separation force, the inclined surfaces of the blocks decompose this force into components in multiple directions. These components are distributed over a larger area, reducing the direct tension on the slot and the insulation board. Through this mechanical dispersion design, the insulation board can better resist vertical separation forces during long-term use, maintain a stable connection, and improve the long-term stability of the entire insulation system.

[0024] Furthermore, the inclined surfaces of the two inclined blocks in the slot are parallel to each other.

[0025] Beneficial effects: The parallel nature of the inclined surfaces of adjacent blocks allows each block to synchronously suppress bidirectional displacement of the insulation board. After the insulation board is inserted into the slot, when the insulation board undergoes lateral or longitudinal displacement, the parallel inclined surfaces of the blocks simultaneously generate a restraining force. During lateral displacement, the inclined surfaces prevent the insulation board from moving; during longitudinal displacement, they also play a role in preventing displacement.

[0026] Furthermore, a friction layer is fixedly connected to the side of the inclined block away from the slot.

[0027] Beneficial effect: The friction layer design allows it to generate sufficient friction when relative sliding occurs between the insulation board and the connector, preventing the sliding from happening.

[0028] Furthermore, several L-shaped reinforcing ribs are fixedly connected to the main body plate.

[0029] Beneficial effects: The L-shaped reinforcing ribs improve the bending stiffness of the main plate. The L-shaped structure can increase the moment of inertia of the main plate, enabling it to better resist deformation when subjected to bending forces.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The following detailed description illustrates the specific implementation method:

[0039] Example 1:

[0040] This embodiment provides a wall insulation connector, specifically as follows: Figure 1 As shown, the main body plate 1 has an L-shaped structure. One end of the main body plate 1 is provided with a wall-connecting groove assembly for connecting to the wall. The wall-connecting groove assembly includes a central groove 2 and several side grooves 3. The side grooves 3 are located on both sides of the central groove 2 and are perpendicular to the central groove 2. The installer can use expansion bolts to fix the wall to be connected to the main body plate 1 through the central groove 2 and several side grooves 3. The other end of the main body plate 1 is used to insert into the insulation board and connect with the insulation board to realize the connection between the insulation board and the wall.

[0041] In particular, conventional connectors that rely on friction or bolts are prone to relative displacement between the wall and the insulation board under long-term external forces. Therefore, the main panel 1 is designed with a fastening assembly on the side away from the central groove 2 to support adjacent insulation boards. Between the fastening assembly and the main panel 1, a connecting assembly is provided to reinforce the connection between the insulation board and the main panel 1. The fastening assembly includes a fastening block 4, which is a box-shaped structure with one open end. The fastening block 4 is slidably connected to the main panel 1. Compared to conventional one-piece fastening connectors with sheet-like supporting components (such as flat plates or L-shaped thin sheets), the box-shaped fastening block 4 (supporting component) designed in this scheme forms a mechanical frame similar to a box beam through a three-dimensional enclosure design of the side walls, top surface, and bottom surface. When the insulation board is subjected to external force, the load is evenly transferred to the main board 1 through the side wall of the box-shaped fastening block 4, avoiding local deformation or tearing of the sheet structure due to single-point force; the side wall of the box-shaped fastening block 4 can limit the lateral displacement of the insulation board it supports, forming a "wrap-up" constraint.

[0042] The fastening block 4 has symmetrical connecting plate grooves 7, and the main body plate 1 has connecting plate holes 8 corresponding to the positions of the connecting plate grooves 7. The installer uses expansion screws to connect the fastening block 4, the main body block and the insulation board into one unit through the connecting plate grooves 7 and the connecting plate holes 8.

[0043] Combination Figure 1 and Figure 2 As shown, the fastening block 4 includes a first fastening plate 401 and a second fastening plate 402 that slide and engage with each other. Compared with the receiving plate used to support adjacent insulation boards in the existing fastening plate connectors, the fastening block 4 in this solution adopts a separate structure. The relative positions of the first fastening plate 401 and the second fastening plate 402 can be manually adjusted by the installer to adapt to the different thicknesses of adjacent insulation boards or wall construction errors, thus avoiding the problems of installation failure or local stress concentration caused by the fixed size of the traditional integrated receiving plate.

[0044] The top surface of the first snap-fit ​​plate 401 and the bottom surface of the second snap-fit ​​plate 402 are both provided with snap-fit ​​components for securing the edges of the corresponding insulation boards. Each snap-fit ​​component includes a U-shaped slot 9. Figure 2 and Figure 3 As shown, inclined blocks 10 are integrally fixedly connected to both sides of the inner wall of the slot 9. The inclined surfaces of the two inclined blocks 10 in the same slot 9 are parallel to each other. The design of the two parallel inclined surfaces of the inclined blocks 10 in the slot 9 can disperse the vertical detachment force of the insulation board located in the slot 9. While not affecting the insulation board's role in being inserted into the slot 9, it increases the resistance of the insulation board to detach from the slot 9 during use.

[0045] Combination Figure 2As shown, the connecting assembly includes several wedge-shaped blocks 5 and wedge-shaped grooves 6. The wedge-shaped grooves 6 are symmetrically opened at the bottom of the first fastening plate 401 and the top of the second fastening plate 402. The wedge-shaped grooves 6 are integrally fixed to the surface of the main body plate 1 corresponding to the positions of the wedge-shaped blocks 5. When the installed insulation board has a tendency to move laterally due to wind vibration or temperature change, the insulation board will generate a lateral force on the slot 9. This force is transmitted to the first fastening plate 401 or the second fastening plate 402 through the slot 9. The wedge-shaped blocks 5 and the wedge-shaped grooves 6 are in planar contact and engaged, which improves the resistance to the detachment force of the first fastening plate 401 or the second fastening plate 402 from the main body plate 1 and avoids loosening.

[0046] Example 2:

[0047] As attached Figure 3 As shown, the difference from Embodiment 1 is that a friction layer 11 is adhered to the side of the inclined block 10 away from the slot 9. The friction layer 11 is preferably a sheet film made of nitrile rubber. The rough surface texture of the friction layer 11 can increase the sliding resistance between the insulation board and the slot 9, effectively suppressing micro-displacement caused by wind vibration or temperature difference. In addition, the friction layer 11 has a certain degree of elasticity, which can absorb the hard collision energy between the insulation board and the metal slot 9, avoid abnormal noise and reduce the risk of breakage of the insulation board edge due to high-frequency impact.

[0048] Example 3:

[0049] As attached Figure 1 As shown, the difference from Embodiment 2 is that several L-shaped reinforcing ribs 12 are welded on the main body plate 1. The design of the L-shaped reinforcing ribs 12 can resist the bending deformation caused by wind load or the self-weight of the insulation board by increasing the moment of inertia of the main body plate 1 (i.e. increasing the bending stiffness of the L-shaped main body plate 1).

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
