Description

Technical Field

[0001] The utility model relates to the technical field of wall panels, in particular to a prefabricated thermal insulation wall panel. Background Technique

[0002] As the name implies, a thermal insulation wall must play the role of heat preservation and insulation and maintaining the stability of the indoor temperature. It refers to an engineering practice that uses a certain fixing method (bonding, mechanical anchoring, bonding + mechanical anchoring, spraying, casting, etc.) to fix a heat-insulating material with a relatively low thermal conductivity (that is, good heat preservation and insulation effect) to the building wall body, increasing the average thermal resistance value of the wall body, so as to achieve the effect of heat preservation or insulation.

[0003] For example, the prior art Chinese patent publication number "CN207260367U" provides a prefabricated thermal insulation wall, including outer concrete, triangular installation holes, reinforcing bars, steel bar sleeves, inner concrete, installation meshes, thermal insulation boards, and installation grooves. Four groups of triangular installation holes are drilled at the four corners of the outer concrete and the inner concrete. The outer concrete is connected to the inner concrete through reinforcing bars and steel bar sleeves. The installation groove of the outer concrete is provided with a thermal insulation board, and an installation mesh is bolted to the right side end of the thermal insulation board, a prefabricated thermal insulation wall.

[0004] The device includes outer concrete, triangular installation holes, reinforcing bars, steel bar sleeves, inner concrete, installation meshes, thermal insulation boards, and installation grooves. Four groups of triangular installation holes are drilled at the four corners of the outer concrete and the inner concrete. The outer concrete is connected to the inner concrete through reinforcing bars and steel bar sleeves. The installation groove of the outer concrete is provided with a thermal insulation board, and an installation mesh is bolted to the right side end of the thermal insulation board, a prefabricated thermal insulation wall.

[0005] In the existing prefabricated thermal insulation wall panels, the internal thermal insulation structure is relatively simple, the connection strength is insufficient, and loosening and gaps are likely to occur, resulting in a reduction in the thermal insulation performance of the thermal insulation wall panels, and the stability of the thermal insulation structure of the thermal insulation wall panels cannot be effectively improved. At the same time, there is also a lack of a sealing structure on the side of the thermal insulation wall panel. When the thermal insulation wall panels are assembled, the connection gap between two adjacent thermal insulation wall panels is relatively large, and they cannot be tightly connected and the gap cannot be reduced, affecting the thermal insulation performance of the thermal insulation wall panels.

Connecting rods are embedded between the outer concrete layer and the inner concrete layer. A connection groove is formed in the middle of the connecting rods. Clamping plates are connected to both ends of the surface of the connecting rods.

[0009] Furthermore, a sealing ring is bonded to the outer edge of the outer concrete layer. A second release film is bonded to the outer layer of the sealing ring.

[0010] Furthermore, the insulation layer is made of fiberglass wool material, and the waterproof layer adopts a polyethylene waterproof membrane structure.

[0011] Furthermore, the reinforcement plate is made of basalt fiber reinforced plastic, and the thermal insulation layer adopts a foamed polystyrene insulation board structure.

[0012] Furthermore, the bonding layer adopts marble glue material, and the first release film adopts a polyethylene film structure.

[0013] Furthermore, the connecting rods are evenly distributed between the outer concrete layer and the inner concrete layer. Both ends of the connecting rods are respectively inserted into the inner parts of the outer concrete layer and the inner concrete layer, and are connected by concrete pouring.

[0014] Furthermore, the connecting rods pass through the insulation layer, the waterproof layer, the reinforcement plate and the thermal insulation layer.
