Embodiment 1

[0021] A polystyrene foam plastic board used for geothermal floor insulation, the thickness of the polystyrene foam plastic board is 4cm, and circular grooves with a diameter of 3cm are distributed on its upper surface in a square lattice of 4cm×4cm. The depth of the circular grooves is 1.2cm, and each circular groove is connected through the horizontal and vertical ventilation grooves perpendicular to each other. The width of the horizontal and vertical ventilation grooves is 0.8cm, and the depth is 0.7cm. A tenon is provided on one side of the plastic plate, and a corresponding tenon is provided on the opposite side.

Embodiment 2

[0023] like image 3 As shown, a polystyrene foam plastic board used for geothermal floor insulation layer, the thickness of the polystyrene foam plastic board is 4cm, and the circular dots with a diameter of 3cm are distributed on the upper surface according to the square lattice of 5cm×5cm. Groove, the depth of the circular groove is 1.2cm, and each circular groove is connected to each other through the horizontal ventilation groove and the vertical ventilation groove. The included angle between the ventilation groove and the longitudinal ventilation groove is 45 degrees, a tenon is arranged on one side of the foam plastic plate, and a corresponding tenon is arranged on the other side opposite to it.

Abstract

The invention discloses a polystyrene foam plastic board for thermal insulating layers of geothermal floors. Circular grooves, transverse ventilation slots and longitudinal ventilation slots are uniformly formed in the upper surface of the polystyrene foam plastic board, and the circular grooves are mutually communicated through the transverse ventilation slots and the longitudinal ventilation slots; one side face of the polystyrene foam plastic board is provided with a tenon, and the opposite other side face of the polystyrene foam plastic board is provided with a corresponding mortise. The foam plastic board can solve the problem that a wood floor is heated non-uniformly due to poor heat transfer between the thermal insulating layer of the existing geothermal floor and the wood floor.

Description

technical field [0001] The invention specifically relates to a polystyrene foam plastic board used for the thermal insulation layer of a geothermal floor. Background technique [0002] The geothermal floor is to spread the heating in the form of coils on the ground. The heat dissipation is mainly concentrated in the height where the human body benefits. It has the advantage of high thermal efficiency. Lay the wooden floor on it again, due to the poor heat transfer performance of the insulation material, the floor will be hot in places with heating coils, but not hot in places without heating coils. Another layer of metal heat conduction layer is added between the floor and the insulation material, but this is not conducive to the control of production costs. Contents of the invention [0003] The object of the present invention is to solve the problem of poor heat transfer between the existing geothermal floor insulation layer and the wooden floor, and provide a polystyre...
