Sanitary Floor

The present invention relates to an arrangement for a sanitary floor such as a floor in a bathroom, a laundry or the like, said floor includes at least one fall of the same towards at least one floor drain.

Today a big problem is to provide sanitary floors having adequate and correct fall to a floor drain provided therein. The most common method is to cast the floor or fill up the same with concrete so that a fall is formed in a direction towards the floor drain. It has been found to be very difficult, especially after construction, for example to create said top casting or filling so that the outflow towards the floor drain functions satisfactory without having water remaining in pools in different locations on the floor surface. During new construction often uses prefabricated wiping rails inclinded towards the floor drain, which are later removed. After that a first casting is carried out and whereafter the marks after the rails have been filled up by concrete. This has been found to be very expensive and time consuming.

The object with the present invention is to provide an arrangement for a sanitary floor of the type mentioned above by aid of which the drawbacks stated above have been eliminated. The distinguishing features according to the invention are stated in the claims enclosed.

The invention makes it possible in a very easy way to provide a sanitary floor having a fall towards a floor drain which means that problems concerning a correct outflow no longer exist. The floor can be mounted on an already existing even supporting surface and a method using castings in different stages is no longer implemented. After mounting the block elements forming the sanitary floor the floor is finished to serve as a support for a sanitary carpet of plastic material or a suitable type of clinker or tile floor. A special treatment of the block elements is not necessary after mounting the same since each respective block element is prefabricated. The block elements often only need to be cut off along the edges which are turned towards the outer walls of the room in question. In the case of large floor surfaces, the outermost elements only have to be raised to a level which is the same as adjacent elements by aid of special spacers. In the cases the different block elements forming the floor in their edge sections are provided with groove and tenon, it is guaranteed that a correct passage in the same level can be provided without a filling up casting afterwards. This is an advantage in the event that the floor is later covered by a plastic carpet.

The invention shall be described closer below with reference to the drawing enclosed, in which

FIG. 1 shows a schematic plane view of a sanitary floor according to the present invention.

FIG. 2 shows a cross section along the line II--II in FIG. 1.

FIG. 3 shows an embodiment of the groove and tenon feature of the invention .

As can be seen from the drawings an embodiment of the invention refers to a sanitary floor 1, such as a floor to a bathroom, laundry or the like, said sanitary floor comprises a number of separate, prefabricated block elements 2, 3 and 4. These elements are, in the example illustrated, of a square formation. One of the block elements 2 comprises a floor drain 5, towards which the upper surface of this element inclines in a predetermined angle from the respective outer edge. The block elements 2-4 are supported by a bedding 6 against which their lower surface 7 contacts and extends parallelly. The upper surface 8 of the block elements 2-4 is, to the contrary, inclined a predetermined angle or inclines towards the floor drain 5 included in one or some of the elements.

In the example illustrated the floor 1 comprises of five corner block elements 4, each of which is provided with two inclinations which are inclined towards each other along a diagonal over the element in question. The floor 1 further comprises twelve block elements 3 which only are provided with an inclination towards one and the same direction and finally the block element 2 provided with the floor drain 5 itself which has four surfaces which incline or are inclined towards the floor drain 5.

Spacers 9 are used in order to have the outermost mounted block elements situated in level with and form smooth passages to adjacent block elements. This arrangement can be of an advantage in the cases of larger floor surfaces, where a bigger number of block elements are required. The area of the spacers 9 corresponds mainly to the block elements.

Referring now to FIG. 3, the block elements 2-4 can also be provided with groove 10 and temon 11 in their edge sections in order to achieve smoothness and in one and the same level lying passages between the different block elements 2-4, this which can be especially suitable if, for example, a plastic carpet shall be mounted on the floor formed by the block elements.
