Description
Technical Field
[0001] This utility model relates to a built-in mesh vacuum insulation exterior wall structure, belonging to the field of insulation structure technology. Background Technology
[0002] In building construction, the thermal insulation performance of external walls directly affects the building's energy consumption and occupant comfort. Vacuum insulation technology, due to its excellent thermal insulation effect, is widely used in external wall insulation systems. Existing vacuum-insulated external wall structures typically use direct pasting or simple fixing methods to place vacuum insulation panels between walls. However, this method has several drawbacks: firstly, the fixing stability of vacuum insulation panels is poor, and they are prone to displacement during construction, affecting the integrity of the insulation layer; secondly, the overall strength of vacuum insulation panels is not high, making them susceptible to damage. Utility Model Content
[0003] This utility model provides a built-in mesh vacuum insulation exterior wall structure, which solves the problems existing in the background art.
[0004] This utility model relates to a built-in mesh vacuum insulation exterior wall structure, including a concrete exterior wall, a vacuum insulation board, and a concrete protective layer. The vacuum insulation board includes a supporting mesh plate, in which a vacuum insulation board is provided. An insulation protective plate covering the outside of the supporting mesh plate is provided. The supporting mesh plate has multiple mounting holes evenly distributed, and a positioning tube is fixed in the mounting holes. The two ends of the positioning tube are flush with the outer ends of the insulation protective plate. A tie rod is provided in the inner hole of the positioning tube. The inner end of the tie rod has at least one binding hole. A fixing wire is provided in the binding hole. The two ends of the fixing wire are bent and fixed to the upper and lower adjacent longitudinal steel bars of the main steel cage in the concrete exterior wall. A wire mesh is fixed in the concrete protective layer at the outer end of the tie rod.
[0005] As a preferred option, the positioning tube comprises a nylon inner tube and a metal outer tube, with flanges at both ends of the nylon inner tube covering the ends of the metal outer tube. This solves the problem of cold and thermal bridging at the tie rod while ensuring structural strength.
[0006] As a preferred embodiment, the tie rods at both ends of the positioning tube are threaded with an inner limiting disc and an outer limiting disc, respectively. The inner and outer limiting discs are in contact with the positioning tube on the side closest to the vacuum insulation plate. This allows for better control of the lateral position of the vacuum insulation plate.
[0007] As a preferred embodiment, the outer side of the limiting disc is provided with a limiting sleeve that fits onto the tie rod, and limiting plates are provided on both sides of the wire mesh. A locking bolt is fitted in the middle of the outer limiting plate, and the locking bolt is threaded into the threaded inner hole at the outer end of the tie rod. The inner limiting plate is fixed to the limiting sleeve. This allows for quick positioning of the lateral position of the wire mesh and facilitates the clamping and fixing of the wire mesh.
[0008] As a preferred embodiment, each vacuum insulation panel has a splicing boss and a splicing groove on opposite sidewalls. During splicing, the boss is inserted into the groove to form a tight fit.
[0009] As a preferred option, the outer surface of the thermal insulation panel is provided with multiple vertical guide channels, the cross-section of which is an arc shape larger than a semicircle. The guide channel structure allows concrete to enter, increasing the overall connection between the vacuum insulation panel and the two sides, and better preventing detachment.
[0010] As a preferred embodiment, the inner limiting disc, on the side furthest from the insulation and protective board, is equipped with an anti-detachment sleeve that fits onto the tie rod. The outer wall of the anti-detachment sleeve is evenly covered with anti-detachment barbs. During concrete pouring, the concrete firmly encapsulates the anti-detachment sleeve and barbs, creating a mechanical interlocking effect that effectively prevents axial displacement of the tie rod, further strengthening the connection between the tie rod and the concrete exterior wall, and ensuring the long-term stability of the exterior wall structure.
[0011] This utility model has the following beneficial effects: This structure provides stable support for the vacuum insulation panel through the supporting grid plate, and the insulation protection panel forms effective protection. With the coordinated fixing of positioning tubes, tie rods and fixing wires, a reliable connection between the insulation panel and the main steel cage is achieved. The wire mesh can also enhance the strength of the concrete protective layer, prevent cracking and falling off, and greatly improve the overall structural stability and insulation durability. In addition, the positioning tube can position the tie rod installation position without drilling holes in the vacuum insulation panel, thus avoiding damage to the vacuum insulation panel.

An insulation protective board 4 covering the outside of the supporting grid plate 2 is provided. Multiple mounting holes are evenly provided on the supporting grid plate 2. A positioning tube is fixed in the mounting hole. The two ends of the positioning tube are flush with the outer ends of the insulation protective board 4. A tie rod 5 is provided in the inner hole of the positioning tube. The inner end of the tie rod 5 is provided with at least one binding hole. A fixing wire 15 is provided in the binding hole. The two ends of the fixing wire 15 are bent and fixed to the upper and lower adjacent longitudinal steel bars of the main steel cage 7 in the concrete exterior wall 8. A wire mesh 9 located in the concrete protective layer 1 is fixed to the outer end of the tie rod 5.
[0015] During construction, the vacuum insulation board is placed in the installation position, and then the tie rod 5 is inserted into the positioning tube. Then, the fixing wire 15 is inserted into the binding hole at the inner end of the tie rod 5. The two ends of the fixing wire 15 are bent and fixed to the upper and lower adjacent longitudinal steel bars of the main steel cage 7 inside the concrete outer wall 8 to complete the fixing. The wire mesh 9 is fixed to the outer end of the tie rod 5, the formwork is erected, and then the concrete outer wall 8 and the concrete protective layer 1 are poured. After the concrete outer wall 8 and the concrete protective layer 1 are dried, the leveling layer, the waterproof layer and the decorative layer are applied to the outside of the concrete protective layer 1.
[0016] Example 2, based on Example 1, includes a nylon inner tube 6 and a metal outer tube 10. Both ends of the nylon inner tube 6 are provided with flanges that cover the ends of the metal outer tube 10. The pull rod 5 is a metal inner rod covered with high-strength plastic.
[0017] The tie rods 5 at both ends of the positioning tube are threaded with a limiting inner disc 14 and a limiting outer disc 11, respectively. The limiting inner disc 14 and the limiting outer disc 11 are in contact with the positioning tube on the side closest to the vacuum insulation board. When the tie rod 5 is inserted into the positioning tube, the limiting inner disc 14 and the limiting outer disc 11 are respectively inserted on both sides of the vacuum insulation board. After the tie rod 5 is tied and fixed to the main steel cage 7, the positions of the limiting inner disc 14 and the limiting outer disc 11 can be rotated to limit the vacuum insulation board.
[0018] The outer side of the limiting outer plate 11 is provided with a limiting sleeve 17 that fits onto the pull rod 5. Limiting plates 18 are provided on both sides of the wire mesh 9. A locking bolt 12 is fitted in the middle of the outer limiting plate 18. The locking bolt 12 is threaded into the threaded inner hole at the outer end of the pull rod 5.

The limiting plates 18 on both sides are used to press the wire mesh 9.
[0019] Each vacuum insulation panel has a splicing boss 13 and a splicing groove on its opposite sidewalls. When adjacent vacuum insulation panels are spliced, the splicing boss 13 and the splicing groove cooperate to position and connect them.
[0020] Multiple vertical guide channels 20 are provided on the outer surface of the thermal insulation and protective board 4. The cross-section of the guide channel 20 is an arc shape larger than a semicircle. When the concrete outer wall 8 and the concrete protective layer 1 are poured, the concrete enters into the guide channel 20 to form anti-detachment ribs.
[0021] The inner limiting plate 14, away from the thermal insulation and protective plate 4, is provided with an anti-detachment sleeve 19 that is fitted onto the tie rod 5. The outer wall of the anti-detachment sleeve 19 is evenly provided with anti-detachment barbs 16. When the concrete outer wall 8 is poured, the concrete encloses the anti-detachment sleeve 19 and the anti-detachment barbs 16, forming an anti-detachment structure.
