[0001] The utility model relates to the technical field of heat-insulating walls, in particular to an exterior wall panel composite heat-insulating layer structure. Background Art

[0002] With the development of modern construction technology, people have put forward higher requirements for the comfort and energy-saving performance of buildings. As the external protective structure of the building, the thermal insulation performance of the exterior wall panel directly affects the building. At present, the thermal insulation technology of the exterior wall panel has become an important part of building energy conservation.

[0003] Current exterior wall insulation technology on the market has several drawbacks. For example, due to cost and construction considerations, single-material insulation brick walls are often used, which have limited insulation performance. Insulation is primarily achieved by increasing wall thickness. This approach not only increases the amount of building materials used and the weight of the building, but also occupies valuable building space, reducing the usable area of ​​the interior. Furthermore, single-material insulation brick walls are prone to material deformation and aging over time, resulting in reduced insulation performance and increased maintenance costs.

[0004] Therefore, a composite thermal insulation layer structure of an exterior wall panel is needed to solve the above technical defects. Utility Model Content

[0005] The purpose of the utility model is to provide an exterior wall panel composite insulation layer structure to solve the problem of limited insulation performance of insulation brick walls made of a single material, as proposed in the above background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite insulation layer structure of an exterior wall panel, comprising an insulation brick wall and an anti-cracking board, wherein the insulation brick walls are stacked layer by layer, and anti-cracking boards are padded between each layer of insulation brick walls, and a grid is provided inside the insulation brick wall, and a plurality of through square intervals are formed in the grid, and each group of square intervals is provided with type A insulation filling material and type B insulation filling material, the type A insulation filling material is polyurethane foam, and the type B insulation filling material is rock wool.

[0007] Preferably, the type A thermal insulation filling material and the type B thermal insulation filling material are arranged at intervals in the length direction and width direction of the thermal insulation brick wall, and four adjacent groups of type A thermal insulation filling materials or type B thermal insulation filling materials form a "cross" structure.

[0008] Preferably, the anti-crack plate is a long rectangular strip, and its length is arranged according to the length of the insulation brick wall.

[0009] Preferably, a connecting groove is processed on one edge of the anti-crack plate, and two groups of anti-crack plates are bonded with adhesive between the connecting grooves. An I-beam sheet is fitted in the connecting groove, and a fixing bolt is fixed between the I-beam sheet and the connecting groove.

[0010] Preferably, the number of connections of the anti-crack plates can be set according to the length of the wall.

[0011] Preferably, the outer wall of the heat-insulating brick wall is installed with a structural base plate, the outer wall of the structural base plate is installed with a waterproof board, the outer wall of the waterproof board is installed with a brick backing plate, and the outer wall of the brick backing plate is installed with an anti-radiation finish board.

[0012] Preferably, the structural base plate, waterproof board, brick backing plate and anti-radiation finish plate are assembled layer by layer, and the gaps at the edges are filled with caulking glue.

[0013] Preferably, the structural base plate, waterproof board, brick backing plate and anti-radiation topcoat board have the same thickness.

[0014] Compared with the existing technology, the beneficial effects of the present invention are as follows: the composite insulation layer structure of the exterior wall panel not only realizes the combination of multiple materials, reduces the weight and thickness of the insulation brick wall, enhances the insulation effect, enhances the overall structural strength of the wall, ensures the stability and deformation resistance of the connection, but also achieves both insulation and waterproofing, can maintain the stability of the indoor temperature, save energy, and improve living comfort;

[0015] (1) By providing an insulating brick wall, a grid, a type A insulating filling material and a type B insulating filling material, and by providing a grid inside the insulating brick wall and adopting a design of filling with type A insulating filling material and type B insulating filling material at intervals, the thermal insulation performance of the wall is effectively improved. The type A insulating filling material is polyurethane foam, which has low density and low thermal conductivity and can effectively reduce heat conduction, while the type B insulating filling material is rock wool, which has good fireproof and sound absorption properties, further enhancing the comprehensive thermal insulation effect of the wall, solving the problem of limited thermal insulation effect of a single material, and utilizing a combination of multiple materials to reduce the weight and thickness of the insulating brick wall and enhance the thermal insulation effect. In addition, the structure of the grid provides stable support to prevent the filling material from shifting or collapsing during long-term use, thereby ensuring the durability and stability of the thermal insulation effect;

[0016] (2) By providing anti-crack plates, I-shaped steel sheets, and fixing bolts, and by adding anti-crack plates as a separation layer in the vertical stacking of the thermal insulation brick wall, and adopting an I-shaped structure for horizontal connection, the overall structural strength of the wall is effectively enhanced. The combination of the I-shaped steel sheets and the fixing bolts ensures the stability and deformation resistance of the connection, solves the problem that traditional walls are prone to cracks and deformation during long-term use, and improves the durability and seismic resistance of the wall. At the same time, the anti-crack plates can prevent the thermal insulation material from thermal expansion and contraction due to temperature changes;

[0017] (3) By setting up a structural base plate, a waterproof board, a brick pad, and an anti-radiation paint board, a multi-level composite structure is adopted on the outer wall of the thermal insulation brick wall.

This multi-level composite structure solves the problem that the wall cannot take into account both thermal insulation and waterproofing. Especially in the high temperature in summer and low temperature in winter, it can maintain the stability of indoor temperature, save energy, and improve living comfort.
