Description

The present invention relates to a floorboard made of plastic for keeping pigs. .

Different types of heating systems are used in pig-rearing stables. This includes different types of heated floors. An economically advantageous and physiologically well-seeded floor heating system is disclosed in CS 213 996. copyright certificate for an air-conditioned compartment for pigs. The heating element used here is a metal tensioned floor plate, which is electrically heated to a surface temperature of 38 ° C. The disadvantage of this solution, due to the significant weight and the limited lifetime caused by the aggressive stabbing, is that it cools down and withdraws from the piglets very quickly after the electricity is switched off or off. Thus, the above-mentioned solution can only be used after being connected to the electric current. Operationally, the rapid transfer of heat from the metal to the surface of the floorboard by the metal heater can be disadvantageous, as during intensive cooling, such as when piglets are removed, surface heating is accelerated so much that both the surface and interior temperature of the floorboard are reduced.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the disadvantages hitherto encountered in keeping piglets warm by providing a heating system which optimally provides for both the mode and amount of heat delivered to the piglets in accordance with physiologically sound principles.

SUMMARY OF THE INVENTION The object of the present invention is solved by a multipurpose floor suitable for pigs comprising at least one heat-insulating layer, at least one heat-conducting layer and an electric surface-mounted heating body with connecting wires embedded between the heat-insulating layer and the heat-conducting layer. in essence, the heat-insulating layer is made of a plastics material such as expanded polypropylene having a heat conductivity coefficient of less than 0.20 N.m'LK * ¹ , while the heat-conducting layer is made of a modified plastics material such as polypropylene. ' having λ »'thermal conductivity! has a coefficient of n ^J smoother than 0.35 Winr'.K ' ¹ and to which a heat-conducting additive such as finely ground limestone powder has been added.

Foamed polypropylene, compared to foamed polystyrene, which is often used for thermal insulation purposes, is more robust and thus more resistant to damage by pressure, tensile and bending, and is resistant to chemicals and the microclimate of the barn.

A further advantage is that it is non-absorbent, well formed and weldable. In addition, it is less flammable than polystyrene.

The thermal insulating and heat-conducting layers, between which an electric surface heater is embedded, e.g. rectangular in shape, overlap each other and are bonded together firmly and insoluble.

In a preferred embodiment of the present invention, the thermal insulating and heat-conducting layers form a two-part, rectangular and also rectangular front and side cover, wherein the electrical surface heater with conductive conductor, wherein the inlet conduit for the surface heater passes through a passageway and through a heat-insulating layer of the casing into a heat-insulating pad that contacts the heat-insulating layer. The heat-conductive layer, which forms the upper part of the casing, is provided with at least two transverse extruded reinforcing ribs, while the outer surface of the heat-insulating and heat-conductive layers is firmly and insoluble connected.

The electric surface heater is formed by a surface-mounted electric shielding wire which is embedded in an electrical insulating fabric. Preferably, the conductor of the electrical surface heater is provided on one of the narrow side walls of the floor panel, in the middle thereof.

The electrical connection between the electrical surface heater and the connection conduit is accessible and releasably formed in a cavity formed inside the thermal insulating layer which is hermetically sealed from the outside. The opening of the cavity can be sealed either by means of a plastic screw or by covering the aperture with a plastic sheet which is connected to the surrounding surface on the outside of the heat-insulating layer of the floorboard by a visible welding seam. By heating the welding seam, the plastic sheet can be removed and, if necessary, the electrical connection becomes accessible.

The invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. In the drawing, la.

The polypropylene thermal insulating layer 1, which is located on the bottom of the floor panel when the surface heater is turned on, i.e. in contact with the ground, prevents the heat of the surface heater 35 from escaping downwards. In contrast, the upper thermal insulation layer 2 on which the piglets are lying provides heat transfer from the surface heater 3 towards the top surface of the floor panel. 40

The electric surface heater 3 is embedded between the thermal insulating layer 1 and the thermal conductive layer 2, which layers are welded along their circumference to form a compact floor polish. 45
