IMPROVEMENTS IN AND RELATING TO A SANITARY FLOOR

Abstract: The present invention relates to an arrangement for a sanitary floor in bathrooms, laundries or the like, said floor (1) comprises at least one fall of the same towards at least one floor drain (5). The upper layer of said floor (1) consists of at least two separate, adjacent, rectangularly formed block elements (2, 3; 4), at least one block element (2) of which comprises a floor drain (5), the respective block element having a lower surface (7) which is parallel with a bedding (6) supporting the block elements (2-4) but an upper surface (8) which inclines or is inclined a predetermined angle towards a floor drain provided in the same or in any adjacent block element.

Description: IMPROVEMENTSINANDRELATINGTOASANITARYFLOOR The present invention relates to an arrangement for a sani¬ tary 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 enough 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 very difficult especially afterwards for example during repair to create said top casting or filling so that the outflow towards the floor drain functions satisfactory without having water to remain in pools in different locations on the floor surface. During new construction one often uses prefabricated wiping rails inclined towards the floor drain, which are removed after that a irst 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 elimi¬ nated. The distinguishing features according to the inven¬ tion are stated in the claims enclosed. Thanks to the invention it is possible in a very easy way to provide a sanitary floor having a fall towards a floor drain made in the same which means that any problems no longer exist what concerns a correct outflow. The floor can be mounted on an already existing even supporting surface and the method using castings in different stages is no longer actual. After mounting the block elements forming the sani¬ tary 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 the respective block element is prefabricated but they often only need to be cut off along the edges turned towards the outer walls of the room in question and 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 is guaranteed that a correct passage in the same level can be provided without a filling up casting afterwards, which is an advantage in the case that the floor later on shall be 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 and Fig. 2 shows a cross section along the line II-II in fig. l. As can be seen from the drawing an embodiment of the inven¬ tion refers to a sanitary floor 1, such as a floor to a bathroom, laundry or the like, said sanitary floor consists of 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 ele¬ ment 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 ele¬ ments 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 l consists 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 l 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 pass¬ ages to adjacent block elements, which can be of an advan¬ tage in the cases of larger floor surfaces, where a bigger number of block elements are required. The area of the spa¬ cers 9 corresponds mainly to the block elements. The block elements 2-4 can also be provided with groove and tenon in their edge sections in order to achieve smooth and in one and the same level lying passages between the different block elements 2-4, which can be especially suit¬ able if, for example, a plastic carpet shall be mounted on the floor formed by the block elements.

Claims: Cl aims 1. An arrangement for a sanitary floor in bathrooms, laundries or the like, said floor (1) comprises at least one fall of the same towards at least one floor drain (5) , characterized in that the upper layer forming the floor (1) consists of at least two separate, rectangularly formed, adjacent block elements (2, 3,-4) , at least one block element (2) of which comprises a floor drain (5) , the respective block element (2,3;4) having a lower surface (7) which is parallel with a bedding (6) supporting the block elements (2-4) but an upper surface which inclines or is inclined a predetermined angle towards a floor drain provided in the same or in any adjacent block element. 2. An arrangement according to claim l, characterized in that the floor (l) formed by the block elements (2-4) comprises at least two corner block elements (4) , each of which having two falls, which are inclined towards each other and the rest consisting of block elements (3) only provided with one fall towards one and the same direction with the exception of a block element (2) provided with a floor drain (5) . 3. An arrangement according to claim 1, characterized in that lower elements in the form of spacers (9) having mainly the same bottom area as the block elements (2-4) are mountable under the actual block element for obtaining of smooth passages to adjacent block elements. 4. An arrangement according to claim l, characterized in that each block element (2,3;4) is formed with groove and tenon at least at adjacent edge sections.
