Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation walls, in particular to a polymerized polystyrene board composite thermal insulation wall. Background Art

[0002] Polystyrene composite insulation boards are made of polystyrene foam sheets as the insulation matrix, composited with inorganic material slurry. Polystyrene sheets with Class A combustion performance are bonded with graphite extruded sheets with Class B combustion performance, bonded with a special adhesive, and then pressurized to form a composite insulation board. Currently, polystyrene composite insulation boards are often fixed to the base wall using bonding mortar and anchor bolts, resulting in poor connectivity. Furthermore, the entire wall's insulation layer is composed of multiple panels spliced ​​together, with a lack of fasteners between adjacent panels, resulting in low overall connection strength. Furthermore, during construction, wall paint is applied directly to the exterior of the insulation layer, increasing the insulation layer's load-bearing capacity and potentially causing cracking and shedding.

The provision of the keels increases the connection between the insulation boards and the base wall, and the keels can provide support for the insulation boards. The fasteners are used to connect the adjacent insulation boards, thereby increasing the integrity and preventing the insulation boards from falling off. A steel mesh is provided between the insulation layer and the paint layer, and the steel mesh provides an overall framework for the paint layer. The steel mesh is fixedly connected to the keels, thereby dispersing the load brought by the paint layer to the insulation boards and enhancing the strength and durability of the insulation layer.

[0006] Specifically, the interior of the base wall is further provided with planted steel bars, and the keel is fixedly connected to the planted steel bars, thereby increasing the stability between the keel and the base wall and improving the bearing capacity of the keel.

[0007] Furthermore, the upper and lower sides of the keel are provided with rectangular slots that can be engaged with the insulation board. After the insulation board and the keel are engaged, the movement of the insulation board in a direction perpendicular to the base wall can be restricted, thereby improving the stability of the insulation layer.

[0008] As for the arrangement structure of the insulation panels, several of the insulation panels are arranged in an upper and lower staggered manner, which can not only improve the overall stability and stress strength, but also avoid the formation of continuous splicing gaps that cause excessive heat loss.

[0009] Preferably, an anti-cracking layer is provided between the wire mesh and the coating layer, which can protect the thermal insulation layer, prevent cracking, waterproof and impact-resistant, and the anti-cracking layer directly covers one side of the wire mesh, so that the wire mesh can offset part of the load brought by the anti-cracking layer to the thermal insulation layer.

[0010] As a preferred embodiment, an insulation strip is provided between the insulation board and the fastener, corresponding to the keel. The vertical width of the insulation strip is not less than the vertical width of the keel, and the horizontal length is not less than the horizontal length of the keel. The addition of the insulation strip can insulate the joint gap between the upper and lower adjacent insulation boards, preventing the formation of thermal bridges at the keel, which would reduce the thermal insulation effect of the insulation layer.

[0012] Furthermore, the insulation board is provided with a plurality of circular fixing grooves that cooperate with the fasteners, and the connecting piece is configured to be fixed in the fixing grooves. By pre-arranging the fixing grooves on the insulation board, there is no need to drill holes on site, which facilitates the positioning and installation of the fasteners.
