Steel wire lattice frame polystyrene one-side net external wall heat insulation sheet

The utility model relates to a steel wire mesh frame polystyrene one-side mesh external wall heat insulating plate comprising a plate body, fitting pieces connected with an external wall, and connecting pieces connected to the external wall. A polystyrene foam plate is used as the plate core of the plate body. The surface of one side of the plate body is fixed with a steel wire mesh frame. The steel wire mesh frame is smeared with cement mortar. The steel wire mesh frame is welded into mesh pieces through the intertexture of horizontal wires and vertical wires. One end of the steel wire mesh frame and oblique wires which are fixed through mesh pieces are lunged into the polystyrene foam plate core and then are connected to back wires. The fittings are meshed. The connecting pieces are steel U-shaped pieces and expansion bolts. The utility model saves steel, can improve the heat-insulating property of building structure, can improve connecting integrity and fastness with walls, and can prevent crack and wall skin falling off.
