Description

Technical Field

[0001] The present invention relates to the technical field of building thermal insulation materials, and particularly to an exterior wall thermal insulation board for buildings that is easy to install. Background Art

[0002] The exterior wall thermal insulation board is composed of materials such as polymer mortar and fiberglass mesh cloth. The on-site bonding construction of the exterior wall thermal insulation board is the preferred material to meet the current energy-saving requirements of building construction and improve the exterior wall thermal insulation level of industrial and civil buildings. It is also the first choice for energy-saving renovation of existing buildings. It is used in places such as high-rise exterior walls, indoor shopping malls, and industrial equipment.

[0003] According to the Chinese patent with the publication number CN220203032U, an exterior wall thermal insulation board, an exterior wall thermal insulation board anchoring structure, and an exterior wall thermal insulation wall system are disclosed. The anchor is in the combined form of an expansion tube, a pressure plate, and an expansion nail. The expansion section of the expansion tube has a thicker tube wall compared to the main section. Firstly, a larger expansion degree can be obtained to ensure that the expansion tube is closely attached to the inner wall of the wall hole in the wall, and the grasping force is more stable. Secondly, the expansion section has a thicker tube wall and is not easily broken during expansion, having better anti-extrusion ability. During concealed construction, the quality of the expansion tube after installation can be ensured. This solution drives the plate body to closely adhere to the wall surface through the expansion tube assembly and the expansion nail. However, when the thermal insulation board shakes or is impacted, the anchor is likely to cause the installation of the thermal insulation board to become loose due to the shaking.

[0004] According to the Chinese patent with the publication number CN115405002A, an installation device for an exterior wall thermal insulation board and a decorative board is disclosed. When in use, the steel belt can be first installed on the wall. At this time, the two side belts are respectively movably installed on the side walls of the wall. Then, the moving column is inserted into the circular groove. With the movement of the moving column, the fixed ring fixed thereto moves accordingly. With the movement of the fixed ring, the elastic strip fixed thereto moves accordingly. With the movement of the elastic strip, the clamping strip moves accordingly. When the clamping strip moves to the limit groove, the elastic strip recovers its deformation to complete the clamping, so that the steel belt can be connected to the wall and is not easily loosened. This solution is designed with elastic strips and clamping strips to fix the steel belt to the wall, and then anchor nails are used to install the thermal insulation board on the wall. This installation design cannot achieve sufficient strength tightening adjustment and anti-detachment protection when installing the thermal insulation board. Summary of the Invention

[0015] Preferably, an anti-deflection groove is provided at the lower edge of the vacuum insulation panel, an insert block is fixed to the upper edge of the vacuum insulation panel, and both side edges of the vacuum insulation panel are arranged in a "Z"-shaped structure.

[0016] Preferably, a sealing opening is provided on the outer surface of the insulation board body close to the fastening pin, and a protective cover is interference fit in the sealing opening, and sealant is filled between two adjacent insulation board bodies.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the exterior wall insulation board for buildings is easy to install, and the docking mechanism, the self-locking mechanism and the tightening mechanism are linked and arranged; the inner locking hook and the outer locking hook are driven to clamp the limit block by adjusting the fastening pin of the docking mechanism; and the self-locking mechanism follows the movement of the guide member to rotate the swing arm to drive the gas spring rod to lock the angle between the wide body support arm and the outer locking hook; and then the limit block is fastened by the synchronous movement of the clamping plate of the tightening mechanism and the inner locking hook, so that the clamping plate squeezes and pushes the two top pins to be inserted into the inner wall of the positioning hole of the vacuum insulation board to increase the anchoring strength, thereby ensuring the exterior wall insulation board has a stable installation function with anti-fall protection.

[0018] 1. The exterior wall insulation board for the building is easy to install. The fastening pin on the surface of the insulation board body is rotated by a tool, so that the fastening pin and the limit block thread transmission drive the fastening pin to push the guide piece, thereby driving the inner lock hook and the outer lock hook to engage with the limit block, and when the support block moves in the forward direction, it will move through the gear on one side to mesh with the rack on the surface of the outer hexagonal screw head. When the swing arm drives the gas spring rod to rotate to stagger with the wide body support arm, the output rods at both ends of the gas spring rod will automatically extend and expand and abut between the wide body support arm and the hook tail of the outer lock hook. The output rod of the gas spring rod locks the angle between the wide body support arm and the outer lock hook, which can prevent the inner lock hook and the outer lock hook from being clamped by the limit block;

[0019] 2. The building uses an exterior wall insulation board that is easy to install. When the inner locking hook and the outer locking hook are locked and tightly abutted against both sides of the limit block, the limit block will squeeze one end of the inner clamping plate, so that the clamping plate rotates around the damping shaft and drives the protrusion to clamp the side of the limit block away from the expansion bolt, ensuring a lateral tightening effect between the limit block, the docking mechanism and the expansion bolt. At the same time, the two ejector pins are pushed out from both sides of the inner locking hook and inserted into the inner wall of the positioning hole of the vacuum insulation panel through the clamping plate, ensuring that the vacuum insulation panel can increase the anchoring strength through the connection with the ejector pin.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 8 , the present invention provides a technical solution: an exterior wall insulation board for buildings that is easy to install, including an insulation board body 1, a vacuum insulation board 2, and expansion bolts 6. A vacuum insulation board 2 is arranged on one side of the insulation board body 1, and one side of the vacuum insulation board 2 is adhesively butt-jointed to the wall 4 through an adhesive 3.

[0034] Positioning holes 203 are provided in the middle and one of the corners of the surface of the vacuum insulation board 2. By providing positioning holes 203 in the middle and one of the corners of the surface of the vacuum insulation board 2, the expansion bolts 6 corresponding to the positioning holes 203 can firmly install the vacuum insulation board 2 on the wall 4. And when the insulation board body 1 and the vacuum insulation board 2 are regularly spliced and arranged on the wall 4, it can ensure that the expansion bolts 6 are evenly distributed on the wall 4 and prevent excessive damage to the surface of the wall 4 due to multiple expansion bolts 6 at local positions of the wall 4; a limiting block 5 is vertically arranged inside the positioning hole 203, an expansion bolt 6 is inserted into the wall 4, and the external hexagonal head of the expansion bolt 6 extends out of the surface of the wall 4. A docking mechanism 7 is arranged on one side of the external hexagonal head of the expansion bolt 6. The docking mechanism 7 includes a connecting seat 701 integrally formed with the external hexagonal head. A rotating shaft 702 is inserted into the middle of the connecting seat 701. An internal locking hook 703 is rotatably connected to the rotating shaft 702. External locking hooks 704 sleeved on the rotating shaft 702 are arranged on both sides of the internal locking hook 703. Both the internal locking hook 703 and the external locking hook 704 are composed of a hook head and a hook tail. And a bayonet for clamping with the limiting block 5 is provided on one side of the hook head. The hook tail of the internal locking hook 703 is movably connected to two narrow body arms 705. A wide body arm 706 is movably connected to the side of the hook tail of the external locking hook 704. A guiding member 707 is connected between the narrow body arm 705 and the wide body arm 706. A self-locking mechanism 8 is arranged on one side of the guiding member 707 close to the wide body arm 706. The self-locking mechanism 8 includes a gear 801 arranged on one side of the guiding member 707. A rack 804 meshing with the gear 801 is arranged on the external hexagonal head of the expansion bolt 6.

[0035] The middle part of the connecting seat 701 is provided with a U-shaped opening, through which the hook tails of the inner locking hook 703 and the outer locking hook 704 can be conveniently rotated and adjusted in the connecting seat 701. And the outer side of the connecting seat 701 is set as an arc surface structure matching the positioning hole 203. When the connecting seat 701 is docked with the vacuum insulation panel 2, the arc surface structure on the outer side of the connecting seat 701 is inserted into the positioning hole 203, which can play a role in positioning and preventing deviation.

[0036] The guiding member 707 is composed of a guiding shaft and a supporting block fixed at one end of the guiding shaft. The expansion bolt 6 is provided with a telescopic channel near the middle part of the expansion bolt 6, and the telescopic channel is slidably inserted with the guiding shaft of the guiding member 707. And a groove is provided on the side of the supporting block away from the guiding shaft. A return spring a708 abutted against the telescopic channel is sleeved outside the guiding shaft of the guiding member 707, and the side surface of the supporting block of the guiding member 707 is movably connected with the gear 801.

[0037] A fastening pin 709 is threadedly connected to the middle part of the limiting block 5. One end of the fastening pin 709 extending through the inner locking hook 703 abuts against the supporting block of the guiding member 707. The inner hexagonal head at the other end of the fastening pin 709 is inserted into the heat preservation board body 1. The supporting block abuts against one end of the fastening pin 709 through the groove, so that the fastening pin 709 will not deviate when pushing the supporting block to move.

[0038] During specific implementation, the expansion bolt 6 is firmly installed inside the wall body 4, so that the part of the expansion bolt 6 exposed outside the wall body 4 has the function of resisting pulling. Then, the positioning hole 203 of the vacuum insulation panel 2 is aligned with the outer hexagonal head of the expansion bolt 6, so that the inner locking hook 703 and the outer locking hook 704 are inserted into the positioning hole 203, and it is ensured that the inner locking hook 703 and the outer locking hook 704 are docked with the limiting block 5. At this time, the fastening pin 709 on the surface of the heat preservation board body 1 is rotated by a tool, so that the fastening pin 709 performs positive thread transmission with the limiting block 5, thereby making one end of the fastening pin 709 push the supporting block of the guiding member 707, so that the guiding shaft of the guiding member 707 slides forward along the telescopic channel of the expansion bolt 6 and compresses the return spring a708 to contract and deform.

[0039] When the guide member 707 moves toward the outer hexagonal screw head of the expansion bolt 6, the guide member 707 will pull the narrow support arm 705 and the wide support arm 706 to move toward the inside of the connecting seat 701 through the support block, and the narrow support arm 705 and the wide support arm 706 will pull the hook tails of the inner locking hook 703 and the outer locking hook 704, so that the inner locking hook 703 and the outer locking hook 704 rotate around the connecting seat 701 through the rotating shaft 702. At this time, the inner locking hook 703 and the outer locking hook 704 are locked. The angle will gradually become smaller, while the angle between the wide support arm 706 and the outer locking hook 704 and the angle between the narrow support arm 705 and the inner locking hook 703 will gradually become larger, so that the inner locking hook 703 and the outer locking hook 704 can be engaged with the limit block 5 through the bayonet of the hook head, ensuring that the insulation board body 1 and the vacuum insulation board 2 can be installed on the surface of the wall 4 to a limited extent, and the opening degree of the inner locking hook 703 and the outer locking hook 704 is limited by the threaded connection between the fastening pin 709 and the limit block 5.

[0040] See also Figures 5 - 9 , swing arms 802 coaxially connected to the gear 801 are also provided on both sides of the support block of the guide member 707, and a gas spring rod 803 is installed at one end of the swing arm 802 away from the support block. When the inner locking hook 703 and the outer locking hook 704 are in an unlocked state, two wide support arms 706 are provided to block the two output rods of the gas spring rod 803. When the inner locking hook 703 and the outer locking hook 704 are in a locked state, the gear 801 on the guide member 707 will complete the meshing rotation with the rack 804. At this time, the swing arm 802 will drive the gas spring rod 803 to break away from the contact with the wide support arm 706 when rotating.

[0041] In specific implementation, when the fastening pin 709 pushes the support block of the guide member 707 to move forward in the direction of the outer hexagonal screw head of the expansion bolt 6, the guide member 707 slides linearly along the expansion bolt 6 through the guide shaft to prevent the support block from tilting and shaking, and when the support block moves in the forward direction, it will move through the gear 801 on one side to positively mesh with the rack 804 on the surface of the outer hexagonal screw head. When the gear 801 and the rack 804 are positively meshed, they will drive the swing arms 802 on both sides of the guide member 707 to rotate forward. When the swing arms 802 drive When the gas spring rod 803 rotates to be offset from the wide support arm 706, the output rods at both ends of the gas spring rod 803 will automatically extend and expand, so that the output rods at both ends of the gas spring rod 803 abut between the wide support arm 706 and the hook tail of the outer locking hook 704. Therefore, when the fastening pin 709 of the exterior wall insulation board breaks after long-term use, the output rod of the gas spring rod 803 locks the angle between the wide support arm 706 and the outer locking hook 704, thereby preventing the inner locking hook 703 and the outer locking hook 704 from being disengaged from the clamping of the limit block 5.

[0042] See also Figures 5 - 8 , Figure 10 and Figure 11A receiving cavity is formed in the middle of the inner locking hook 703, and a tightening mechanism 9 for secondary clamping is further provided on the inner locking hook 703. The tightening mechanism 9 includes a clamping plate 901 rotatably connected to the receiving cavity through a damping rotating shaft;

[0043] A convex block is integrally formed on the edge of the clamping plate 901 close to the limiting block 5. A cylindrical cavity vertically communicating with the receiving cavity is penetrated through the middle of one end of the inner locking hook 703, and a top pin 903 is slidably connected in the cylindrical cavity. Moreover, a protrusion is provided on the inner wall of the cylindrical cavity. A reserved groove for the sliding of the top pin 903 is formed on the outer side of the top pin 903, and a return spring b902 abutted against the protrusion is arranged in the reserved groove. A double-sided inclined surface is arranged on the edge of the clamping plate 901 close to the convex block, which facilitates the clamping plate 901 to squeeze the top pin 903 through the double-sided inclined surface during rotation. Moreover, when the top pin 903 moves, it will squeeze the return spring b902 between the reserved groove and the protrusion. By arranging the return spring b902, the stability of the top pin 903 during movement can be ensured.

[0044] During specific implementation, when the hook heads of the inner locking hook 703 and the outer locking hook 704 are butted on both sides of the limiting block 5 and are still in an unlocked state, the clamping plate 901 in the inner locking hook 703 will be hidden in the receiving cavity due to the limitation of the damping rotating shaft. When the inner locking hook 703 and the outer locking hook 704 are locked and tightly abut against both sides of the limiting block 5, the limiting block 5 will squeeze one end of the inner clamping plate 901, causing the clamping plate 901 to rotate around the damping rotating shaft, so that the convex block at the other end of the clamping plate 901 buckles the side of the limiting block 5 away from the expansion bolt 6. Since the expansion bolt 6 is installed on the wall body 4 with a tensile resistance effect, the clamping plate 901 has a secondary pressurization and clamping effect when buckling the limiting block 5, ensuring a lateral tightening effect among the limiting block 5, the docking mechanism 7, and the expansion bolt 6;

[0045] While the clamping plate 901 rotates around the damping rotating shaft, the clamping plate 901 will squeeze the top pin 903 in the inner locking hook 703 through the double-sided inclined surface at the edge, causing the top pin 903 to slide outwards along the cylindrical cavity in the inner locking hook 703. When the clamping plate 901 blocks between the two top pins 903, the two top pins 903 can be led out from both sides of the inner locking hook 703 and inserted into the inner wall of the positioning hole 203 of the vacuum insulation panel 2, ensuring that the vacuum insulation panel 2 can increase the anchoring strength through the connection with the top pin 903.

[0046] Please refer to Figures 1 - 4, a deviation prevention groove 201 is provided at the lower edge of the vacuum insulation panel 2, an insertion block 202 is fixed at the upper edge of the vacuum insulation panel 2, and the two side edges of the vacuum insulation panel 2 are arranged in a "Z" shape; a sealing port is provided on the outer surface of the insulation board body 1 near the fastening pin 709, and a protective cover 101 is press-fitted in the sealing port. The protective cover 101 is press-fitted in the sealing port on the outer surface of the insulation board body 1 to hide and protect the fastening pin 709 through the protective cover 101, and the gap where the fastening pin 709 is located is blocked by the protective cover 101, which can ensure the aesthetics of the outer surface of the insulation board body 1; a sealant 102 is filled between two adjacent insulation board bodies 1. Filling the sealant 102 in the splicing gap between two adjacent insulation board bodies 1 can prevent rainwater from entering between the vacuum insulation panel 2 and the wall body 4.

[0047] During specific implementation, when horizontally splicing the exterior wall insulation board, the adjacent vacuum insulation panels 2 arranged horizontally are successively abutted and assembled through the "Z" shaped side edges. When vertically splicing the exterior wall insulation board, the upper vacuum insulation panel 2 is positioned and docked with the insertion block 202 on the upper edge of the lower vacuum insulation panel 2 through the deviation prevention groove 201 at the lower edge, ensuring the role of deviation prevention assistance during vertical splicing.

[0048] In summary, the expansion bolts 6 are equally spaced and driven into the wall body 4, and an adhesive 3 is applied to the wall body 4. The positioning holes 203 of the vacuum insulation panel 2 are aligned with the outer hexagonal heads of the expansion bolts 6. The limiting blocks 5 of the vacuum insulation panel 2 are locked by the inner locking hooks 703 and the outer locking hooks 704, ensuring that the exterior wall insulation board is quickly installed on the building exterior wall. Finally, the exterior wall insulation board is horizontally and vertically spliced, facilitating the exterior wall insulation board to insulate and heat the building exterior wall through the vacuum insulation panel 2. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
