The invention relates to a multilayer floor or sub-floor to be dried out its edges opening out ventilation channels, which are formed by covered slots, and with Means for evacuating moist air from the ventilation ducts.

In a known floor or sub-floor of this type (German Patent 926 033) is as Means for removing moist air from the ventilation ducts are provided with a fan through which warmed air is forced through the ventilation ducts.

In this known floor or sub-floor, the moisture is not removed evenly, because the air pushed through the ventilation ducts inevitably makes its way through these ducts cools down and therefore, under certain circumstances, at the end of its path, the moisture absorbed at the beginning can no longer convey further, because the distances to be covered by the warmed air are different are long and because the resistance to the air flow is inevitable for the flow conditions unfavorable channel routing is uneven.

There is thus the technical task of a floor for the purpose of its uniform dehumidification to equip with means that pass the moist air and cool it down in the ventilation ducts impede.

In the case of a floor or sub-floor of the specified type, this object is achieved by that on a soil layer to be dried out a second layer with high vapor diffusion resistance is glued that the slots in either the first or second layer to the dividing line of the both layers are open and closed by the other layer and that in the ventilation channels Heating wires are built in.

The embedding of heating wires in floor layers is known (German patent specification 421233). With this arrangement, however, the moisture from the ground cannot be removed for this reason alone because ventilation ducts are not provided in this known floor.

In the floor or subfloor designed according to the invention, the heating wires, which emit a certain amount of heat per unit length, heat the humid air in the ducts and generate the vapor pressure that drives the humid air out of the ducts. Because, on the one hand, there is a higher vapor pressure in places with greater moisture and, on the other hand, the air is prevented from flowing away

ker is heated and thus a higher vapor pressure is created, are the same with regard to the Moisture different initial conditions in the lower layer to be dried out by itself and with simple means there will be a very even drying out of the lower layer of the Reached the floor. The arrangement designed according to the invention can also be used as permanent floor heating be used.

Two embodiments of the invention are shown in the drawing and explained below, show it

Fig. 1 and 2 cross-sections through floors or sub-floors that are laid on a raw ceiling,

F i g. 3 shows a plan view of a floor or sub-floor according to FIG. 1 and 2.

An insulation layer 2 and a floor layer 3 to be dried out are applied to a raw ceiling 1. The soil layer 3 to be dried out can, for example, use synthetic anhydrite be made and consist of a cohesive covering or prefabricated screed panels. The mutual arrangement of prefabricated screed panels is shown in FIG. 3.

On the bottom layer 3 to be dried is a second layer 4 (cover layer) with high vapor diffusion resistance glued on, which in the embodiment according to FIG. 1 on their bottom over has the entire width distributed, ventilation channels forming slots 5. These ventilation ducts are about 5 mm high and about 6 mm wide. Their mutual distance is about 4.5 to 6 cm. In heating wires 6 are built into these ventilation ducts. On the second layer 4 can be known per se Way, walking surfaces, for example made of linoleum or plastic, can also be attached.

Claims (1)

i 255 899 In the execution form according to FIG. 2 are the Slots 5 in the bottom layer 3 to be dried out are also arranged distributed over the entire width. Claim: Multi-layer floor or sub-floor to be dried out with opening out at its edges Ventilation channels, which are formed by covered slots, and with means for removing moist air from the ventilation ducts, characterized in that that on a bottom layer (3) to be dried out a second layer (4) with high vapor diffusion resistance is glued that the slots (5) located either in the first or second layer to the dividing line of the two layers are open and closed by the other layer and that in the ventilation ducts (5) Heating wires (6) are installed.
