The support element (2) is a floor grate. The grate comprises several beams (3). The beams (3) are interconnected by several transverse beams (4). The spaces between the beams (3) form the slots or openings. The beams (3) extend from the working surface to the lower surface of the floor grate, and the slots or openings between the beams (3) of the same support element (2) taper from the working surface to the lower surface of the floor grate. In one of the said slots or openings an insertable element (9) is provided made of rubber or elastic synthetic material. The insertable element (9) extends from the inner space of the slot or opening to directly below, on one line with the work surface, or above it. The support element (2) is made of concrete and is a part of the element of the stall (1) floor. The insertable element (9) is a part of the prefabricated element (1) of the stall (1) floor and made with the ability to be inserted into a slot or opening provided in the working surface of the stall (1) floor prefabricated element. The shape and dimensions of the insertable element (9) such that it can be mounted accurately in the slot or opening.
