Description

Technical Field

[0001] The utility model belongs to the technical field of exterior wall panels, and particularly relates to an assembled thermal insulation exterior wall panel. Background Art

[0002] An assembled thermal insulation exterior wall panel is a building component prefabricated in a factory and then transported to a construction site for assembly and installation. Such exterior wall panels usually adopt advanced materials and processes, have excellent thermal insulation performance, can effectively block the heat exchange between indoors and outdoors, and greatly reduce the energy consumption of buildings.

[0003] The structure of the thermal insulation exterior wall panel is exquisitely designed and is usually composed of multiple layers of materials. For example, a graphic code thermal insulation panel applicable to the exterior wall of a building disclosed in the utility model patent with the authorized patent publication number CN203238876U includes: a metal decorative layer, a substrate, and a thermal insulation layer disposed between the metal decorative layer and the substrate. The thermal insulation layer is bonded to the metal decorative layer and the substrate respectively by polyurethane foaming agent and sealed with polyurethane foaming agent at the edges. The thermal insulation layer is formed by bonding multiple pieces of rock wool. In the processing of such thermal insulation exterior wall panels, a press is required to apply pressure to ensure the bonding effect. At the same time, the bonded thermal insulation layer may shift during the pressing process, so secondary cutting is required, and waste materials are generated at the same time, resulting in material waste. To solve the above problems, an assembled thermal insulation exterior wall panel that can improve production efficiency and reduce production processes is needed. Summary of the Invention

[0004] In view of the above problems, the utility model provides an assembled thermal insulation exterior wall panel, which well solves the problems in the prior art that the thermal insulation exterior wall panel needs to be bonded under pressure, and the thermal insulation layer is prone to shift during the pressing process, requiring secondary cutting and easily generating waste materials, resulting in material waste.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows: an assembled thermal insulation exterior wall panel, including a housing, the housing includes a housing one and a housing two, the inner sides of the housing one and the housing two are both fixedly connected with a grid layer, a bonding layer is disposed between the grid layers, the bonding layer is provided with a plurality of connection holes, and fixing parts are disposed in the connection holes. Each fixing part includes two connecting columns and a tension bolt. The two connecting columns are fixedly connected to the inner sides of the housing one and the housing two, and the tension bolt passes through one of the connecting columns and is threadedly connected to the other connecting column.

[0006] Furthermore, side plates one and side plates two are respectively disposed at the edges of the housing one and the housing two. An insertion plate is disposed on the side plate one, and an insertion groove is opened on the side plate two. The insertion plate is inserted into the insertion groove.

[0007] Further, an overflow glue hole is formed in the second side plate, and the overflow glue hole communicates with the insertion slot.

[0008] Further, the adhesive layer includes a heat preservation layer and protective layers adhered to both sides of the heat preservation layer.

[0009] Further, the connecting column includes a first connecting column and a second connecting column. The first connecting column and the second connecting column are respectively fixedly connected to the inner sides of the first housing and the second housing. The outer side surface of the second connecting column fits with the inner side surface of the connecting hole. The length of the second connecting column is less than the thickness of the adhesive layer, and the length of the second connecting column is greater than the sum of the thicknesses of the heat preservation layer and one of the protective layers.

[0010] Further, a jack is formed in the second connecting column, and the first connecting column is inserted into the jack.

[0011] Further, reinforcing discs are arranged at the bottoms of the first connecting column and the second connecting column, and the reinforcing discs are fixedly connected to the outer shell.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By arranging the grid layer, the utility model improves the structural strength of the outer shell and forms a cavity in the product itself, improving the heat preservation and heat insulation effects. At the same time, by arranging the connecting column in cooperation with the connecting bolt, the first housing and the second housing are pulled against each other to directly form good adhesion and fixation of the adhesive layer. At the same time, since the fixing part is inserted into the connecting hole, it effectively prevents the offset of the adhesive layer during the pressing process and avoids secondary cutting and trimming of the edge of the adhesive layer.
