Description

Technical Field

[0001] This utility model belongs to the field of building insulation board technology, specifically relating to a modular installation structure for vacuum insulation boards. Background Technology

[0002] In the construction industry, wall insulation performance is crucial for building energy efficiency and occupant comfort. Vacuum insulation panels, with their low thermal conductivity (0.004-0.008), have been experimentally applied in the market. Traditional vacuum insulation panels are installed and fixed by adhesive anchors, which is prone to detachment, affecting insulation performance and building safety. Some modern vacuum insulation panels are fixed to the reinforcing cage within the main wall using anchors and connected to the inner formwork of the cast-in-place main wall using tie bolts. However, this structure results in poor insulation between adjacent insulation panels, affecting overall insulation performance, and the anchor installation requires drilling holes at the support strips, which can easily damage the insulation panels. Utility Model Content

[0003] Therefore, it is necessary to provide a modular installation structure for vacuum insulation panels to address the existing technical problems.

[0004] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows: A modular installation structure for vacuum insulation panels includes multiple vacuum insulation panels. Each vacuum insulation panel is equipped with anchor rods, and the inner ends of the upper and lower anchor rods are fixedly connected to an inner template. Protective plates are fixed to the outer walls of each vacuum insulation panel. The inner sides of the opposite protective plates of each vacuum insulation panel are provided with mutually cooperating pressing bosses. Reinforcing screws are provided on the pressing bosses. Anti-loosening barbs are provided on the middle part of the anchor rods and the outer walls of the inner ends of the reinforcing screws. An insulating filling layer is filled between the protective plates outside the pressing bosses. A protective sleeve fixed to the vacuum insulation panel is fitted on the outer side of each anchor rod, and the two end faces of the protective sleeve are flush with the two side walls of the vacuum insulation panel.

[0005] Each vacuum insulation panel comprises multiple vacuum insulation boards, with support strips between adjacent boards. The inner side of each vacuum insulation board has a crack-resistant mortar protective layer, while the outer side has a polystyrene particle layer. A protective sleeve is positioned at the support strips, with limiting bosses at both ends. Limiting grooves are located at the corresponding limiting bosses of the polystyrene particle layer and the crack-resistant mortar protective layer. The support strips enhance the overall rigidity of the vacuum insulation panel, preventing bending deformation during installation or concrete pouring, and providing a stable support foundation for the anchor rods. The combination of the crack-resistant mortar protective layer and the mesh fabric improves the crack resistance of the inner side of the insulation panel. The polystyrene particle layer and the wire mesh enhance the structural strength and impact resistance of the outer side of the panel, protecting it from environmental damage. The cooperation of the limiting bosses and grooves ensures the protective sleeve is positioned at both ends, preventing displacement during use and ensuring stable protection of the anchor rods.

[0006] The anchor rod is a variable diameter rod with an outer diameter larger than the inner diameter. The outer pressing boss has a threaded hole that mates with the reinforcing screw, and the inner pressing boss has an open groove that mates with the outer wall of the reinforcing screw. The opening of the open groove faces upward. Before the upper and lower vacuum insulation panels are joined, the reinforcing screw is screwed into the threaded hole. Then, during the joining, the reinforcing screw enters the open groove, which facilitates the joining of the mating pressing bosses. Furthermore, the installation of the reinforcing screw does not affect the joining of the pressing bosses.

[0007] The protective board has limiting flanges on both its inner and outer sides. The ends of the polystyrene particle layer and the crack-resistant mortar protective layer have limiting recesses that engage with these flanges. The engagement of the limiting flanges and recesses ensures a tight connection between the protective board and the insulation board. The outer end of the insulation filling layer covers the outer limiting flanges. A recessed filling groove is located in the middle of the protective board, into which the insulation filling layer is inserted. This filling groove allows for a fuller filling of the insulation filling layer, effectively sealing the joints between adjacent boards, reducing thermal bridging, and ensuring overall insulation performance.

[0008] Each vacuum insulation panel has binding holes on its anchor rods and reinforcing screws that are not connected to the inner formwork. These binding holes allow the insulation panel to be tied and fixed to the reinforcing cage inside the main wall, further improving the connection stability between the insulation panel and the main wall and preventing the panel from shifting during concrete pouring.

[0009] The polystyrene particle layer contains a steel wire mesh, and the crack-resistant mortar protective layer contains a mesh fabric. The polystyrene particle layer and steel wire mesh enhance the structural strength and impact resistance of the outer side of the panel, protecting it from damage caused by the external environment.

[0010] The outer side of the vacuum insulation panel is successively covered with a leveling mortar layer, a waterproof layer, and a decorative layer. The leveling mortar layer ensures the flatness of the outer side of the insulation panel, providing a good foundation for the subsequent construction of the waterproof and decorative layers; the waterproof layer effectively blocks the intrusion of external moisture, preventing moisture from affecting the insulation performance and panel structure; the decorative layer allows for the selection of appropriate materials according to building requirements, enhancing the building's aesthetic appearance.

[0011] The advantages of this utility model compared with the prior art are: This utility model uses anchor rods to fix the vacuum insulation panel to the inner formwork, and the insulation layer can be installed simultaneously when the main concrete wall is poured, realizing "integrated construction of structure and insulation", which greatly shortens the construction period and reduces labor costs.

[0012] The protective sleeve prevents the anchor rod from damaging the vacuum insulation layer, while the insulation filling layer seals the joints between adjacent insulation panels, effectively reducing the thermal bridging effect and ensuring overall insulation performance.

[0013] The anchor rod's anti-loosening barb design and the reinforcement screws' fixation of the pressing boss, along with multiple reinforcement measures, ensure a firm connection between the insulation board and the main wall, effectively resisting the risk of loosening caused by factors such as temperature changes and wall settlement.

[0015] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0016] Example 1, Reference Figures 1 to 4 This utility model is a modular installation structure for vacuum insulation panels, comprising multiple vacuum insulation panels. Each vacuum insulation panel is provided with an anchor rod 1. The inner ends of the upper and lower anchor rods 1 are fixedly connected to the inner template 3. Protective plates 8 are fixed to the outer walls of each vacuum insulation panel. The inner sides of the opposite protective plates 8 of each vacuum insulation panel are provided with mutually cooperating pressing bosses 19. Reinforcing screws 7 are provided on the pressing bosses 19. Anti-detachment barbs 2 are provided on the middle part of the anchor rod 1 and the outer wall of the inner end of the reinforcing screw 7. The space between the protective plates 8 outside the pressing bosses 19 is filled with a heat insulation filling layer 9. Each anchor rod 1 is covered with a protective sleeve 17 fixed to the vacuum insulation panel. The two ends of the protective sleeve 17 are flush with the two side walls of the vacuum insulation panel.

[0017] During construction, the reinforcing cage 5 is tied at the location where the main wall 4 is to be poured. Then, the inner formwork 3 is placed inside the reinforcing cage 5, and the vacuum insulation board is placed at the installation position outside the reinforcing cage 5. Adjacent vacuum insulation boards are joined together by pressing bosses 19, and anti-detachment barbs 2 are inserted into the installation holes of the pressing bosses 19. Then, anchor rods 1 are inserted into the protective sleeve 17. The inner ends of the longer upper and lower anchor rods 1 pass through the inner formwork 3 and are connected to locking nuts. The middle anchor rods 1 and reinforcing screws 7 are tied and fixed to the reinforcing cage 5 with iron wire. Then, the main wall 4 can be poured. After the main wall 4 is poured and dried, the inner formwork 3 is removed, and the excess part of the anchor rods 1 inside the main wall 4 is cut off. Then, the heat insulation filling layer 9 is filled between the adjacent protective plates 8.

[0018] In Example 2, based on Example 1, each vacuum insulation panel includes multiple vacuum insulation panels 10. Supporting strips 11 are provided between adjacent vacuum insulation panels 10. An anti-crack mortar protective layer 6 is provided on the inner side of each vacuum insulation panel 10, and a polystyrene particle layer 13 is provided on the outer side. A protective sleeve 17 is installed at the supporting strips 11. Limiting bosses are provided at both ends of the protective sleeve 17, and limiting grooves are provided at the corresponding limiting bosses of the polystyrene particle layer 13 and the anti-crack mortar protective layer 6. The anchor rod 1 and the reinforcing screw 7 both adopt a composite structure of metal connecting rods and high-strength plastic to reduce thermal bridging. When installing the protective sleeve 17, mounting holes are opened at the supporting strips 11, and the protective sleeve 17 is embedded into the mounting holes.

[0019] Anchor rod 1 is a variable diameter rod with an outer diameter larger than its inner diameter. The outer pressing boss 19 has a threaded hole that mates with the reinforcing screw 7, and the inner pressing boss 19 has an open groove 18 that mates with the outer wall of the reinforcing screw 7. The opening of the open groove 18 faces upwards. Because anchor rod 1 is a variable diameter rod with an outer diameter larger than its inner diameter, it is relatively easy to insert.

[0020] The protective plate 8 has limiting flanges 20 on both its inner and outer sides. The ends of the polystyrene particle layer 13 and the crack-resistant mortar protective layer 6 have limiting recesses that cooperate with the limiting flanges 20. The outer end of the thermal insulation filling layer 9 covers the outer limiting flanges 20. The protective plate 8 has a recessed filling groove 21 in its middle, into which the thermal insulation filling layer 9 is filled. When filling the thermal insulation filling layer 9, the thermal insulation material will enter the filling groove 21. The thermal insulation filling layer 9 can be made of polyurethane foam sealant or thermal insulation mortar.

[0021] Each vacuum insulation panel has a binding hole 23 on the anchor rod 1 and reinforcing screw 7 that are not connected to the inner template 3 in the middle. When binding the anchor rod 1 and reinforcing screw 7, the wire can be inserted into the binding hole 23 and then bound and fixed to the steel cage 5.

[0022] The polystyrene particle layer 13 is provided with a steel wire mesh 12, and the crack-resistant mortar protective layer 6 is provided with a mesh cloth 22.

[0023] The outer side of the vacuum insulation panel is provided with a leveling mortar layer 14, a waterproof layer 15 and a decorative layer 16 in sequence. After the insulation filling layer 9 is filled, the leveling mortar layer 14 can be applied to the outer side of the vacuum insulation panel, then the waterproof layer 15 can be sprayed on the outer side, and then the decorative layer 16 can be sprayed on the outer side.

[0024] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
