DETAILED DESCRIPTION

[0036] The following is a further detailed description of the specific implementation of the present invention in conjunction 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 intended to limit the present invention.

[0037] Example 1

[0038] This embodiment provides a heat-insulating decorative sandwich panel, such as Figure 1-7 As shown, the invention comprises a metal panel 100 with metal hems 110 around its perimeter, a base plate 200, an insulation board 300 positioned between the metal panel 100 and the base plate 200, and multiple connecting structures. The metal panel 100 is square and has four metal hems 110 around its perimeter. One end of the connecting structure is fixedly connected to the base plate 200, and the other end is connected to the metal hem 110. Part of the connecting structure is movable relative to the metal panel 100. One end of the connecting structure is fixedly connected to the base plate 200, ensuring structural stability; the other end is connected to the metal hem 110, and is designed to be partially movable relative to the metal panel 100. This design allows the metal panel 100 to slightly move along the guide of the connecting structure during thermal expansion and contraction, thereby preventing deformation caused by internal stress accumulation.

[0039] like Figure 1-3 As shown, the outer surface and inner surface of the insulation board 300 are respectively bonded to the metal panel 100 and the bottom plate 200 using adhesive 400. Figure 3 From a certain perspective, the outer surface of the insulation board 300 is its upper surface, and the inner surface of the insulation board 300 is its lower surface. This ensures that the insulation board 300 is tightly bonded to the metal panel 100 and the bottom plate 200.

[0040] The insulation board 300 can be made of insulation materials such as rock wool board, aerogel board or high-strength glass fiber board, and the thickness can be 4-10 cm. The base plate 200 is a fiber cement board, a calcium silicate board, a mortar layer with built-in fiber mesh cloth, cement cloth or an insulation material board with built-in steel mesh. The insulation material board can be a rock wool strip, rock wool board, aerogel board or high-strength glass fiber board.

[0041] like Figure 1-3 As shown, to facilitate installation of the thermal insulation decorative sandwich panel, at least two insertion holes 111 are provided on each of the upper and lower folded edges of the metal panel 100. One end of the connecting structure is located between the base plate 200 and the thermal insulation panel 300, and the other end is fixed to the left and right folded edges of the metal panel 100. By providing two insertion holes 111 on the upper and lower folded edges of the metal panel 100, the metal panel 100 can be quickly installed from the bottom up. The insertion holes 111 are plugged into the anchors fixed to the exterior wall, allowing the metal panel 100 to be easily installed on the exterior wall from the bottom up.

[0042] In order to strengthen the connection performance between the thermal insulation decorative sandwich panel and the exterior wall, such as Figure 1-3 As shown, a fixing plate 500 is fixed to the left and right sides of the base plate 200. The fixing plate 500 includes a connecting straight portion 510, an inclined connecting portion 520, and a fixed straight portion 530. The connecting straight portion 510 is fixed to the base plate 200, and the fixed straight portion 530 is provided with a mounting hole 531. Anchor bolts are fixed to the exterior wall through the mounting holes 531, anchoring the thermal insulation decorative sandwich panel to the exterior wall and further strengthening the connection. The fixed straight portion 530 abuts the exterior wall. Due to the presence of the inclined connecting portion 520, a gap is left between the connecting straight portion 510 and the base plate 200 and the exterior wall. The gap can accommodate bonding mortar, allowing the thermal insulation decorative sandwich panel to be further bonded and fixed to the exterior wall.

[0043] like Figure 1-7 As shown, the connection structure includes an intermediate connecting plate 610 and a first L-shaped connecting plate 620. The first end of the intermediate connecting plate 610 is fixedly connected to the metal folding edge 110. Specifically, the first end of the intermediate connecting plate 610 is fixedly connected to the metal folding edge 110 by rivets. The second end of the intermediate connecting plate 610 is provided with at least two inner screw holes 611, as shown in FIG. Figure 5 As shown, this embodiment takes two as an example. The first L-shaped connecting plate 620 includes a first connecting plate 621 and a second connecting plate 622 arranged perpendicular to the first connecting plate 621. The first connecting plate 621 is fixedly connected to the bottom plate 200 by fixing screws 630. Figure 4 As shown, the fixing screws 630 simultaneously clamp and fix the fixing plate 500 and the first L-shaped connecting plate 620 on the bottom plate 200. Figure 4 、6 As shown, the second connecting plate 622 is located on one side of the insulation board 300 and has an elongated hole 623 corresponding to the position of the inner screw hole 611. The inner screw hole 611 of the intermediate connecting plate 610 and the elongated hole 623 on the second connecting plate 622 are movably connected by a fixing screw 630. That is, the fixing screw 630 is not tightened and can move within the elongated hole 623 to prevent the metal panel 100 from bulging and deforming due to thermal expansion during high temperatures in summer after the metal fold 110 is completely fixed to the first L-shaped connecting plate 620. The first connecting plate 621 and the insulation board 300 can also be further bonded together using adhesive 400. In the connection structure of this embodiment, the intermediate connecting plate 610 is fixed to the metal fold 110 and cannot move relative to it, while the intermediate connecting plate 610 and the first L-shaped connecting plate 620 are connected to each other in a relatively movable manner. The connection structure of this embodiment adopts a partially movable arrangement relative to the metal panel 100. In other optional embodiments, the first connecting plate 621 may also be pre-fixed to the insulation plate 300 using adhesive 400 so that the position of the first connecting plate 621 can remain unchanged when connected with the fixing screws 630.

[0044] Furthermore, the first connecting plate 621 and the insulation plate 300 are bonded with adhesive 400 , that is, the adhesive 400 used to bond the bottom plate 200 and the insulation plate 300 is filled between the first connecting plate 621 and the insulation plate 300 .

[0045] Example 2

[0046] In the first embodiment, the inner side of the heat preservation board 300 is flat. Figure 8 、 9 As shown, the inner surface of the insulation board 300 of this embodiment is provided with a plurality of grooves 310 corresponding to the installation positions of the first connecting plates 621, and the first connecting plates 621 are disposed within the grooves 310. In this way, the grooves 310 can position the first connecting plates 621. After the first connecting plates 621 are disposed within the grooves 310, their surfaces are flush with the inner surface of the insulation board 300. The adhesive 400 can be applied along the same plane during bonding, and the bottom plate 200 can also be placed parallel to the inner surface of the insulation board 300.

[0047] The other structures of this embodiment are consistent with those of the first embodiment.

[0048] Example 3

[0049] The connection structure of the embodiment is partially movable relative to the metal panel 100, while the connection structure of this embodiment is entirely movable relative to the metal panel 100. Specifically, Figure 10-15As shown, the metal folding edge 110 is provided with a connecting hole 112, and the connecting structure includes a hook-type connecting plate 640 and a second L-shaped connecting plate 650. The first end of the hook-type connecting plate 640 has a hook portion 641, and the hook portion 641 is clearance-matched with the hole wall of the connecting hole 112, and the hook portion 641 can move slightly in the connecting hole 112. The second end is provided with at least two internal screw holes 611, and the second L-shaped connecting plate includes a third connecting plate 651 and a fourth connecting plate 652 arranged perpendicular to the third connecting plate 651. The third connecting plate 651 is fixedly connected to the bottom plate 200 by a fixing screw 630, and the fourth connecting plate 652 is located on one side of the insulation plate 300, and a fixing hole 653 corresponding to the position of the internal screw hole 611 is opened on it. The internal screw hole 611 of the intermediate connecting plate 610 is fixedly connected to the fixing hole 653 on the fourth connecting plate 652 by a fixing screw 630. In other optional embodiments, the internal threaded hole of the hook-type connecting plate 640 can be replaced by a circular hole without threads, and the middle connecting plate 610 is fixedly connected to the fourth connecting plate 652 by rivets.

[0050] The other structures of this embodiment are consistent with those of the first embodiment.
