Description
Technical Field
[0001] This invention relates to the field of external wall insulation technology, specifically to an anchored metal-clad external wall insulation structure with decorative covers. Background Technology
[0002] Existing external wall insulation systems mainly include:
[0003] The structure of thin plastering on the outside of insulation board involves attaching the insulation board to the wall, anchoring the insulation layer with disc-shaped anchors, and then covering the anchors with a plastering layer and a finishing layer containing fiberglass mesh. Since the anchors are inside the plastering layer, they are completely invisible. However, the disadvantages are that the plastering process on the outside of the insulation board is complex, the labor cost is high, and there are many problems of detachment and bulging across the country, making it easy to be damaged by external forces.
[0004] The integrated insulation and decorative panel structure consists of each insulation panel with various prefabricated decorative surfaces fixed to the outside, such as metal or thin stone. During installation, each integrated insulation and decorative panel is fixed to the exterior wall using a keel or side-mounted anchors. Because the panels are fixed from the side, the decorative surface of the insulation panel is not damaged, and the anchors are not visible on the surface. However, the disadvantages of this structure are that it requires a large number of keels and side-mounted anchors, the process is complex, and the labor costs are high, resulting in an expensive price.
[0005] Carved metal decorative integrated panels use a metal sheet to wrap a thin polyurethane insulation board, with snap-fit structures on the top and bottom sides. During installation, anchor nails are used to fix the insulation board at the upper snap. These anchor nails are hidden by the upper insulation board and are not visible. While this structure also hides the anchor nails, its disadvantages include the need for specialized equipment to press and manufacture the metal cover panel, making it difficult to produce. More importantly, because it can only be fixed at one side of the groove, thick insulation boards cannot be used, and it may not meet national standards in some areas.
[0006] Chinese patent CN201721517025.4 discloses an L-shaped color steel plate semi-enclosed insulation structure, including an insulation board, a color steel plate, anchors, and an exterior wall. The color steel plate is in an inverted L-shape and surrounds the top and outside of the insulation board. The insulation board is more than 4 cm thick. The bottom of the color steel plate is more than 1 cm longer than the bottom of the insulation board. Multiple insulation boards surrounded by color steel plates are arranged in contact with each other and stacked. The inner surface of the insulation board is in close contact with the exterior wall. The anchors are divided into two rows and fix the insulation board and the color steel plate to the exterior wall. One row of anchors is in the middle of the color steel plate, and the other row of anchors is in the overlapping part of the upper and lower color steel plates. This structure uses anchor nails to anchor the L-shaped metal plate to the exterior wall at the overlap of the upper and lower layers, so the anchor nails are not visible and the decoration is beautiful. However, the disadvantage is that because the anchors are only anchored at the overlap, the width of the metal cover panel is relatively narrow, the overlap part is more, and the construction complexity is increased, so the cost is relatively high.
[0007] To address the shortcomings currently existing in the market, there is an urgent need to improve the technology of anchored metal-clad external wall insulation structures, so as to better ensure the safe operation of external wall insulation structures and promote the development of the construction industry. Summary of the Invention
[0008] The purpose of this invention is to provide an anchored metal-clad exterior wall insulation structure with decorative cover to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, the present invention provides the following technical solution: an anchored metal-clad exterior wall insulation structure with a decorative cover, comprising a metal cover panel and an insulation board. The metal cover panel has a recessed platform with a through hole. A groove is formed inside the recessed platform, and a straw hat gasket and a cover are installed in the groove. The insulation board is fixed to the exterior wall, and the outer surface of the insulation board is covered with the metal cover panel. The metal cover panel is connected to the exterior wall by anchors. The anchors penetrate the through hole and the insulation board. Sealant is filled between the anchors and the cover. The cover is fixed in the groove by the sealant. The straw hat gasket is fitted onto a metal nail, and the metal nail is inserted and fixed in an expansion tube.
[0010] Preferably, the metal cover panel is pressed with evenly distributed recesses, and a circular through hole is opened at the center of the bottom surface of the recesses. The metal cover panel has two forms: one is a flat plate and the other is an L-shaped folded plate. When the metal cover panel is an L-shaped folded plate, a folded edge is provided at the upper edge of the metal cover panel, and the folded edge is fitted into the groove of the insulation board. The metal cover panel is an embossed metal plate.
[0011] Preferably, when the metal cover panels are arranged vertically, the bottom of the upper row of metal cover panels and the top of the lower row of metal cover panels overlap, and the overlapping part of the lower row of metal cover panels is recessed inward to form a step. The width of the step is greater than the overlapping part, and the height of the step is greater than the thickness of the metal cover panels.
[0012] Preferably, the depth of the recess is greater than the sum of the height of the metal nail head plus the thickness of the straw hat pad plus the thickness of the cover plate, and the diameter of the through hole is greater than the diameter of the expansion tube.
[0013] Preferably, the anchor is assembled from an expansion tube, a metal nail, and a straw hat gasket. The anchor connects the metal cover panel, the insulation board, and the exterior wall. After the anchor is fixed, a cover plate is bonded to the recess on the outside of the anchor, and the outer surface of the cover plate is flush with the outer surface of the metal cover panel.
[0014] Preferably, the cover plate is a symmetrical shape, and the cover plate is adapted to the shape of the concave platform.
[0015] Preferably, the straw hat pad has the same shape as the recessed platform, but the straw hat pad and the recessed platform are different in size, and the straw hat pad is fitted into the recessed platform.
[0016] Preferably, the outer wall and the recessed platform are provided with holes at corresponding positions, the expansion tube is inserted into the holes, the head of the metal nail is located on the right side of the straw hat pad, and the tail of the metal nail passes through the straw hat pad and enters the expansion tube.
[0017] Preferably, the reinforcing plate fixed inside the metal cover panel has a cross-section in the shape of a "7". The horizontal part of the reinforcing plate is inserted into the insulation board, and the vertical part of the reinforcing plate is parallel to the metal cover panel. When the reinforcing plate is set at the anchor point, the vertical part of the reinforcing plate must match the recess and the through hole.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The anchored metal-clad exterior wall insulation structure with decorative cover plate has a reasonable structural design. By setting a recessed platform and a cover plate, the anchor is installed in the recessed platform and then covered by the cover plate, which not only ensures the fixing effect of the insulation board, but also ensures the aesthetic appearance of the decoration. Moreover, the recessed platform is not set at the overlap, which allows the use of a wider metal cover plate, saves more construction time, and reduces costs. By setting a metal cover plate on the outside of the insulation board, the plastering process is eliminated, the installation keel is not required, saving labor, and thick insulation boards can be used. It can better ensure the safe operation of the exterior wall insulation structure and promote the development of the construction industry. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1—4. This invention provides a technical solution: an anchored metal-clad exterior wall insulation structure with decorative cover plates, comprising a metal cover panel 1 and an insulation board 4. The metal cover panel 1 has recessed platforms 2, and the recessed platforms 2 have through holes 3. By setting the metal cover panel 1 on the outside of the insulation board 4, the plastering process is eliminated, the installation keel is not required, labor is saved, and thicker insulation boards 4 can be used. The metal cover panel 1 has evenly distributed recessed platforms 2 pressed on it, and a circular through hole 3 is opened at the center of the bottom surface of the recessed platform 2. The metal cover panel 1 has two forms, one being a flat surface. Another type is an L-shaped folded plate. When the metal cover panel 1 is an L-shaped folded plate, a folded edge 13 is provided at the upper edge of the metal cover panel 1, and the folded edge 13 is fitted into the slot 14. The metal cover panel 1 is an embossed metal plate, and the slot 14 is opened on the insulation board 4. When the metal cover panels 1 are arranged vertically, the bottom of the upper row of metal cover panels 1 and the top of the lower row of metal cover panels 1 overlap. The overlapping part of the lower row of metal cover panels 1 is recessed inward to form a step. The width of the step is greater than the overlapping part, and the height of the step is greater than the thickness of the metal cover panel (1).The recessed platform 2 has a groove 12 inside, and a straw hat pad 9 and a cover plate 10 are installed in the groove 12. The depth of the recessed platform 2 is greater than the sum of the height of the metal nail 8 head plus the thickness of the straw hat pad 9 plus the thickness of the cover plate 10. The diameter of the through hole 3 is greater than the diameter of the expansion tube 7. Because a wider metal cover panel 1 can be used, construction time is saved, and costs are reduced. The insulation board 4 is fixed to the outer wall 5. The outer surface of the insulation board 4 is wrapped with the metal cover panel 1, and a reinforcing plate 15 is provided between the insulation board 4 and the metal cover panel 1. The reinforcing plate 15 has a "7" shaped cross-section. The horizontal part of the reinforcing plate 15 is inserted into the insulation board 4, and the folded edge is clamped in the slot 14, which is opened on the insulation board 4. The vertical part of the reinforcing plate 15 is parallel to the metal cover panel 1. When the reinforcing plate 15 is set at the anchor point, the vertical part of the reinforcing plate 15 needs to match the recess 2 and the through hole 3. The reinforcing plate 15 helps to ensure the flatness of the metal cover panel 1. The metal cover panel 1 is connected to the outer wall 5 through the anchor 6. The outer wall 5 has holes at the corresponding positions of the recess 2, and the expansion tube 7 is inserted into the holes. The metal nail 8 passes through the straw hat gasket 9 and enters the expansion tube 7. The anchor 6 passes through the through hole 3 and the insulation board 4. The space between the anchor 6 and the cover plate 10 is filled with sealant 11. The cover plate 10 is fixed in the groove 12 by the sealant 11. The straw hat gasket 9 is fitted onto the metal nail 8, and the metal nail 8 is inserted and fixed in the expansion tube 7. The anchor 6 is assembled from the expansion tube 7, the metal nail 8, and the straw hat gasket 9. The anchor 6 connects the metal cover panel 1, the insulation board 4, and the outer wall 5. After the anchor 6 is fixed, the recess 2 on the outside of the anchor 6... A cover plate 10 is bonded inside, and the outer surface of the cover plate 10 is flush with the outer surface of the metal cover panel 1. The cover plate 10 is a symmetrical shape and is adapted to the shape of the recessed platform 2. By setting the recessed platform 2 and the cover plate 10, the anchor 6 is installed in the recessed platform 2, and then the cover plate 10 is used to cover it, which ensures both the fixing effect of the insulation board 4 and the aesthetics of the decoration. The straw hat pad 9 has the same shape as the recessed platform 2, but the straw hat pad 9 is different in size from the recessed platform 2. The straw hat pad 9 is snapped into the recessed platform 2, and the head of the metal nail 8 is located on the right side of the straw hat pad 9.
[0026] Working principle: When using this anchored metal-clad exterior wall insulation structure with decorative cover, according to the exterior wall insulation construction standards, firstly, the insulation board 4 is glued and fixed to the exterior wall 5. Then, the metal cover panel 1 is placed on the outside of the insulation board 4. Based on the position of the recessed platform 2 on the metal cover panel 1, the position for drilling holes in the exterior wall 5 is determined. Then, the expansion tube 7 is inserted into the drilled holes in the exterior wall 5. After that, the straw hat gasket 9 is fitted onto the metal nail 8. The metal nail 8 is inserted into the expansion tube 7 through the through hole 3 of the recessed platform 2, thus fixing the metal cover panel 1 to the exterior wall 5. Then, the cover 10 is glued to the recessed platform 2 with sealant 11. Since the cover 10 and the metal cover panel 1 have the same color, the anchor 6 is completely covered. From a distance, the decorative surface looks seamless, achieving an aesthetic function. This is the entire working process of the anchored metal-clad exterior wall insulation structure with decorative cover.
[0027] The metal cover panel 1 can be a color steel plate, a color aluminum plate, an embossed plate with a painted surface, or an embossed plate with a fiberglass mesh bonded to it and then sprayed with real stone paint, etc.
[0028] Insulation board 4 can be EPS board, XPS board, PUR board, rock wool board, etc., which are applied to the exterior wall with adhesive. It can also be insulation board 4 formed by mixing the adhesive powder polystyrene particle insulation mortar evenly on site and then applying it to the base wall. In short, the insulation board 4 mentioned in this article is the insulation layer in general articles.
[0029] The proportions of the metal cover panel 1 and insulation board 4 in the accompanying drawings are only for illustrative purposes. The actual thickness of the metal panel is 0.3-0.8 mm, with 0.8 mm being only for use in the lower floors of buildings that are prone to damage. The insulation board 4 is 30-80 mm thick. The difference between the two and the figures is very large. Therefore, the metal cover panel 1 is very thin and light, and it is also lighter than traditional thin plaster. It will be even lighter after using embossed aluminum panels.
[0030] The metal nails in the attached diagram of the instruction manual are pan head screws. In actual production, flat head screws can also be used instead. The concave part of the straw hat washer is also an inverted cone shape that matches the bottom of the flat head screw.
[0031] In actual use, the selection can be made according to the customer's requirements. The most basic option is a flat plate. For higher requirements, an L-shaped folded plate can be selected. Even higher requirements can include steps at the overlapping parts. The highest requirement is to add a reinforcing plate of 15. Of course, the combination can also be selected according to the application area.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
