Description

Technical Field

[0001] The invention belongs to the technical field of exterior wall thermal insulation decorative panels and relates to an inorganic facing layer thermal insulation decorative panel and an exterior wall thermal insulation system. Background Art

[0002] The thermal insulation decorative panel is a thermal insulation panel with both decorative and thermal insulation functions. It is installed on the exterior wall using a construction process that is mainly based on bonding and supplemented by anchors. It has the advantages of being beautiful, waterproof, energy-saving, and easy to construct. It is currently widely used in construction projects.

[0003] However, decorative panels such as metal panels, ceramic thin plates, calcium silicate boards or fiber cement boards in the thermal insulation decorative panels are connected to the thermal insulation panels by bonding with polyurethane glue. Polyurethane glue is an organic glue and its bonding performance can easily deteriorate in hot weather and after long-term use, causing the decorative panels and the thermal insulation panels to separate, making it easy for the decorative panels to fall off the exterior wall, posing a safety hazard.

[0004] In addition, the existing thermal insulation decorative panels use anchors to anchor the upper and lower edges of the panels to the exterior wall. There is no anchoring measure in the middle area of ​​the thermal insulation panels, and the anchoring force of the anchors installed on the exterior wall is relatively small, only about 300N in aerated blocks and only about 600N in concrete. The anchoring force of an thermal insulation decorative panel after installing 4 to 6 anchors is only 1 to 3KN, which is much lower than the bonding force of the thermal insulation decorative panel to the exterior wall. When the bonding force of the decorative panel fails, the safety performance of the panel will be greatly reduced, and further improvement is urgently needed. Summary of the invention

DETAILED DESCRIPTION

[0045] The following will further describe the specific implementation of the present invention in combination with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] Embodiment 1

[0047] This embodiment provides an inorganic facing layer insulation decorative board exterior wall insulation system, such as Figure 1-6 As shown, it includes an inorganic facing layer insulation decorative board, a plurality of anchors 110 and bonding mortar 120 arranged on both sides of the inorganic facing layer insulation decorative board. Figure 1As shown, the anchors 110 are located on the upper and lower sides of the insulation trim panel.

[0048] The inorganic facing layer insulation decorative board includes insulation board 200, inorganic composite layer 300 and decorative surface layer 400 from inside to outside. The insulation board 200 can be made of thermosetting composite polystyrene foam insulation board 200, polyurethane board, polystyrene board, inorganic light aggregate board, foam glass board, silicon graphene insulation board 200 with built-in single-layer steel wire mesh or two-layer steel wire mesh, etc. The inorganic composite layer 300 is composed of polymer mortar layer 310 and wire mesh 320. The polymer mortar layer 310 can be made of anti-cracking mortar, waterproof and breathable mortar, etc. Multiple rows of built-in anchor rods 500 are arranged in the insulation board 200. The wire mesh 320 is a fiber mesh cloth or a galvanized steel wire mesh. At least most of the wire mesh is arranged in the inorganic composite layer 300. The decorative surface layer 400 can be made of putty layer and decorative topcoat. The built-in anchor rod 500 can be made of non-metallic materials such as nylon.

[0049] The two ends of the built-in anchor rod 500 are respectively provided with an inner threaded hole 510 and an outer threaded hole 520. The outer side of the insulation board 200 is provided with a plurality of anchoring plates 600 located in the inorganic composite layer 300. The anchoring plates 600 are provided with a plurality of fixing holes 610 corresponding to the positions of the outer threaded holes 520 of the built-in anchor rod 500 and a plurality of first oblique protrusions 620 arranged obliquely. The outer end of the built-in anchor rod 500 is fixedly connected to the anchoring plate 600 by a first fixing screw 521, and the inner end passes through the insulation board 200 inwardly. The anchoring plate 600 is provided with a first forming hole 630 so that the first oblique protrusion 620 can be stamped and formed on the anchoring plate 600. The inclination direction of the first oblique protrusion 620 is preferably extended obliquely upward toward the outside. In other optional embodiments, the anchoring plate 600 can also be provided on the decorative surface layer 400.

[0050] The same anchor plate 600 is fixedly connected to multiple built-in anchor rods 500 at the same time. By fixing the same anchor plate 600 to multiple built-in anchor rods 500, a more stable support system can be formed. This connection method can effectively disperse the load and reduce the stress borne by a single anchor rod, thereby improving the bearing capacity of the entire structure. Using this connection method, the construction steps can be simplified and the number of positioning times between the anchor plate 600 and the anchor rod can be reduced. This not only reduces the construction difficulty, but also shortens the construction period and improves the construction efficiency.

[0051] The wire mesh is a layer, the anchor plate 600 is located inside the wire mesh, and the anchor plate 600 abuts against the insulation board 200. In other optional embodiments, the anchor plate 600 may also be located outside the wire mesh, and the part where the wire mesh contacts the anchor plate 600 is close to the outside of the insulation board 200, or the part where the wire mesh contacts the anchor plate 600 is spaced from the outer side of the insulation board 200.

[0052] In other optional embodiments, the wire mesh may also be a double-layer mesh. Specifically, the wire mesh includes an inner mesh and an outer mesh. The anchor plate 600 is located on the outside of the inner mesh, and the outer mesh is located on the outside of the anchor plate 600. The portion where the inner mesh contacts the anchor plate 600 is close to the outside of the insulation board 200, or the portion where the inner mesh contacts the anchor plate 600 is spaced apart from the outer side of the insulation board 200.

[0053] like Figure 1 , 2 As shown, the inner end of the built-in anchor rod 500 protrudes from the inner side surface of the inorganic facing layer thermal insulation decorative board. The inner side of the inorganic facing layer thermal insulation decorative board is provided with at least two L-shaped connecting plates 700 distributed up and down and fixed in the inner end threaded hole 510 of the built-in anchor rod 500. The L-shaped connecting plate 700 includes a transition plate 710 and a plug-in plate 720 vertically arranged with the transition plate 710. The transition plate 710 is fixedly connected with the built-in anchor rod 500. The plug-in plate 720 is located on one side of the thermal insulation board 200 and is provided with a plug-in hole 721. The anchor 110 is fixedly connected with the plug-in hole 721 and fixed to the outer wall 100, so that the plug-in plate 720 is anchored to the outer wall 100. In other optional embodiments, the built-in anchor rods corresponding to the upper and lower L-shaped connecting plates 700 can also be staggered and arranged in parallel.

[0054] like Figure 1 , 4 As shown, the transition plate 710 is spaced apart from the insulation board 200, and is provided with a plurality of second forming holes 711 and second oblique protrusions 712 corresponding to the positions of the second forming holes 711. The bonding mortar 120 can be embedded in the interval between the transition plate 710 and the insulation board 200, so that the transition plate 710 can be embedded in the bonding mortar 120 to form a mechanical connection, and the connection is more secure. The length of the second forming hole 711 is greater than the second oblique protrusion 712, and the larger second forming hole 711 facilitates the bonding mortar 120 to pass through, which is conducive to the bonding mortar 120 filling the interval between the transition plate 710 and the insulation board 200. The second oblique protrusion 712 is preferably inclined downward and toward the inside. When the thermal insulation decorative board is bonded to the exterior wall 100, the second oblique protrusion 712 and the inner side of the second forming hole 711 are provided with bonding mortar 120 and bonded to the exterior wall 100. When the bonding mortar 120 is cured, the thermal insulation decorative board not only bonds to the exterior wall 100 but also hangs on the exterior wall 100 by using the second oblique protrusion 712 embedded in the bonding mortar 120 and the bonding mortar fixed in the second forming hole 711, thereby improving the safety performance of the thermal insulation decorative board. In other optional embodiments, the transition plate 710 can also be close to the thermal insulation board 200.

[0055] The bonding mortar 120 of this embodiment is in direct contact with the thermal insulation board 200 . In other optional embodiments, an additional inorganic composite layer 300 may be further provided on the inner side of the thermal insulation board 200 .

[0056] The bonding mortar 120 cooperates with the L-shaped connector and the anchor 110 to form an inorganic facing layer thermal insulation decorative board with a bonding and anchoring installation process. The inorganic facing layer thermal insulation decorative board with a bonding and anchoring installation process is installed on the exterior wall 100 using a construction process that is mainly bonding and supplemented by anchoring.
