[0002] Steel wire mesh insulation board is a composite structure that combines steel wire mesh and insulation materials. Its construction method involves connecting the steel wire mesh to the insulation board, then fixing it uniformly on the template and pouring concrete to form an integrated insulation structure. It has high strength and stability and is widely used in cast-in-place concrete buildings, masonry buildings and the external wall insulation of existing buildings.

[0003] The prior art patent CN213897581U discloses a fixed connection structure for parallel wire mesh insulation boards, including a first wire mesh sheet, a second wire mesh sheet, a third wire mesh sheet, an insulation board, connectors, and fixing plates. It achieves precise fixing of the wire mesh sheet and insulation board through the cooperation of the snap-fit ​​plates and fixing plates. The overall structure is simple, and the installation process is simple and quick. However, during use, due to different construction requirements, it is often necessary to connect wire mesh frames of different specifications to the insulation board. However, the size of the snap-fit ​​plates is fixed and cannot be adjusted, which leads to the snap-fit ​​plates being too large or too small to be suitable for fixing different specifications of wire mesh frames. This limits its applicability and requires further improvement. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a connection structure between a building exterior wall insulation board and a wire mesh frame. This solves the problem that the size of the snap-fit ​​pieces is fixed and cannot be adjusted, which leads to the snap-fit ​​pieces being too large or too small to be compatible with wire mesh frames of different specifications for fixed connection, resulting in a limited range of applications.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a connection structure between a building exterior wall insulation board and a wire mesh frame, comprising an insulation board body and a wire mesh frame body. The wire mesh frame body is fixedly connected to the side of the insulation board body via multiple connecting components. Each connecting component includes a connecting sleeve, a connecting ring slidably fitted on the connecting sleeve, four hollow cylinders uniformly fixed on the outer periphery of the connecting ring, telescopic rods slidably fitted inside each of the four hollow cylinders, multiple triangular teeth fixed on the inner walls of each of the four hollow cylinders, multiple triangular grooves adapted to the triangular teeth opening on the outer periphery of each of the four telescopic rods, L-shaped limiting pieces fixed at the ends of each of the four telescopic rods, and the inner sides of each of the four L-shaped limiting pieces fitting against the wire mesh frame body. An adjustment unit for fixing the connecting ring is connected to the connecting sleeve.

[0006] Preferably, the adjusting unit includes an adjusting bolt, a threaded hole is provided on the outer peripheral side of the connecting ring, the adjusting bolt is threadedly installed in the threaded hole, and a plurality of adjusting holes are evenly provided on the outer peripheral side of the connecting sleeve, one end of the adjusting bolt extends into one of the adjusting holes.

[0007] Preferably, a plurality of guide grooves are evenly provided on the inner circumferential side of the connecting ring, and guide strips are slidably installed in each of the plurality of guide grooves, and the plurality of guide strips are fixed on the outer circumferential side of the connecting sleeve.

[0008] Preferably, one end of the connecting sleeve is fixed with a pressure plate, and the side of the pressure plate is in contact with the side of the insulation board body.

[0009] Preferably, a plurality of positioning pins are evenly fixed on the side of the pressure plate near the main body of the insulation board.

[0010] Preferably, a self-tapping screw is slidably installed inside the connecting sleeve, and one end of the self-tapping screw is fixed with an internal hexagon head that fits against the end of the connecting sleeve.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by rotating the internal hexagonal screw head, can drive the self-tapping screw to automatically screw into the insulation board body, fixing the connecting sleeve to the insulation board body. Then, the telescopic rod is inserted into the hollow cylinder. With the cooperation of the triangular teeth and triangular groove, the telescopic rod can only move into the hollow cylinder and cannot move outward until the four L-shaped limiting pieces are pressed against the four steel wires on the mesh edge of the wire mesh frame body. The wire mesh frame body is then fixedly connected to the insulation board body. As the telescopic rod is continuously inserted, the position of the L-shaped limiting pieces can be adjusted, thus adapting to the installation of wire mesh frame bodies of different specifications. It has a wide range of applications, is simple and convenient to use, and has good practicality.

[0013] 2. Through the coordinated setting of the adjustment unit, when the adjustment bolt is rotated so that its end moves into or out of the adjustment socket, the connecting ring can be fixed or loosened. When the connecting ring is in the loose state, the position of the sliding connecting ring can be adjusted. Thus, the gap between the insulation board body and the wire mesh frame body can be adjusted during installation to adapt and connect wire mesh frame insulation boards of different standards, thus having a wider range of applications.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 4 The present invention will be further described below.

[0021] A connection structure between a building exterior wall insulation board and a wire mesh frame includes an insulation board body 1 and a wire mesh frame body 2. The wire mesh frame body 2 is fixedly connected to the side of the insulation board body 1 by multiple connecting components. Each connecting component includes a connecting sleeve 3, a connecting ring 4 slidably fitted on the connecting sleeve 3, four hollow cylinders 5 evenly fixed on the outer periphery of the connecting ring 4, and telescopic rods 6 slidably fitted inside each of the four hollow cylinders 5. Multiple triangular teeth 8 are fixed on the inner walls of each of the four hollow cylinders 5, and multiple interlocking triangular teeth 8 are formed on the outer periphery of each of the four telescopic rods 6. The corresponding triangular slot 9 is designed to allow the telescopic rod 6 to move only into the hollow cylinder 5 and not outward through the cooperation of the triangular teeth 8 and the triangular slot 9. The ends of the four telescopic rods 6 are all fixed with L-shaped limiting pieces 7. The inner sides of the four L-shaped limiting pieces 7 are in contact with the main body 2 of the wire mesh frame. A self-tapping screw 14 is slidably installed in the connecting sleeve 3. One end of the self-tapping screw 14 is fixed with an internal hexagon head 15 that is in contact with the end of the connecting sleeve 3. An adjustment unit for fixing the connecting ring 4 is connected to the connecting sleeve 3. In use, first insert the self-tapping screw 14 into the connecting sleeve 3, then use a tool to turn the internal hexagon head 15, which will cause the self-tapping screw 14 to automatically screw into the insulation board body 1, fixing the connecting sleeve 3 onto the insulation board body 1. Then, the worker can take the L-shaped limiting piece 7 and insert the telescopic rod 6 into the hollow cylinder 5. At this time, with the cooperation of the triangular teeth 8 and the triangular groove 9, the telescopic rod 6 can only move into the hollow cylinder 5 and cannot move outward. Sequentially press the four L-shaped limiting pieces 7 against the four steel wires on the mesh edge of the wire mesh frame body 2, and the wire mesh frame body 2 can be fixedly connected to the insulation board body 1. As the telescopic rod 6 is continuously inserted, the position of the L-shaped limiting piece 7 can be adjusted, so that different specifications of wire mesh frame body 2 can be adapted for installation. It has a wide range of applications, is simple and convenient to use, and has good practicality.

[0022] like Figure 3 As shown, the adjustment unit includes an adjustment bolt 10. A threaded hole is provided on the outer periphery of the connecting ring 4, and the adjustment bolt 10 is threaded into the threaded hole. Multiple adjustment sockets are evenly distributed on the outer periphery of the connecting sleeve 3, and one end of the adjustment bolt 10 extends into one of the adjustment sockets. When the adjustment bolt 10 is rotated, the threaded hole causes the adjustment bolt 10 to move while rotating, thus allowing it to be moved into or out of the adjustment socket to fix or loosen the connecting ring 4. Furthermore, by inserting the adjustment bolt 10 into the adjustment sockets at different positions, the position of the connecting ring 4 can be adjusted. This allows for adjustment of the gap between the insulation board body 1 and the wire mesh frame body 2 during installation, enabling the connection of wire mesh frame insulation boards of different standards, thus broadening its applicability.

[0023] like Figure 3As shown, multiple guide grooves are evenly distributed on the inner circumference of the connecting ring 4, and guide bars 11 are slidably installed in each of the multiple guide grooves. The multiple guide bars 11 are fixed on the outer circumference of the connecting sleeve 3. Through the cooperation of the guide bars 11 and the guide grooves, the connecting ring 4 can only slide on the connecting sleeve 3 and will not rotate, thus playing a guiding role.

[0024] like Figure 2 As shown, a pressure plate 12 is fixed at one end of the connecting sleeve 3, and the side of the pressure plate 12 is in contact with the side of the insulation board body 1. By setting the pressure plate 12, the force-bearing area between the connecting sleeve 3 and the insulation board body 1 can be effectively increased, thereby allowing it to withstand greater support force.

[0025] like Figure 3 As shown, a plurality of positioning pins 13 are evenly fixed on the side of the pressure plate 12 near the insulation board body 1. By inserting the positioning pins 13 into the insulation board body 1, the position of the pressure plate 12 can be positioned to prevent the pressure plate 12 from sliding during installation.

[0026] In summary: When using this utility model, first rotate the adjusting bolt 10 until its end moves out of the adjusting socket, loosening the connecting ring 4. At this time, the connecting ring 4 can be slid to adjust its position. After adjusting to the appropriate position, rotate the adjusting bolt 10 in the opposite direction until its end is inserted into the adjusting socket, fixing the position of the connecting ring 4. Take the connecting sleeve 3 and place it in the middle of the mesh of the wire mesh frame body 2, pressing the pressure plate 12 against the insulation board body 1, so that the positioning pin 13 is inserted into the insulation board body 1 for positioning. Then, take the self-tapping screw 14 and insert it into the connecting sleeve. 3. Then, use a tool to turn the internal hexagon head 15, which will cause the self-tapping screw 14 to automatically screw into the insulation board body 1, fixing the connecting sleeve 3 onto the insulation board body 1. Then, the worker can take the L-shaped limiting piece 7 and insert the telescopic rod 6 into the hollow cylinder 5. At this time, with the cooperation of the triangular tooth 8 and the triangular groove 9, the telescopic rod 6 can only move into the hollow cylinder 5 and cannot move outward. Until the four L-shaped limiting pieces 7 are pressed against the four steel wires on the mesh edge of the wire mesh frame body 2, the wire mesh frame body 2 can be fixedly connected to the insulation board body 1.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
