A PROCEDURE FOR MANUFACTURING A DEVICE FOR CASTING A SLOPE OF A FLOOR, A DEVICE AND A METHOD FOR CASTING A SLOPE

摘要

A procedure for manufacturing a device (40) intended to be used for casting a slope with correct inclination toward a floor drain (41) provides an element (10) with a first (11) and a second (12) sheet of metal foil, which are arranged in parallel to each other, and a core (13) of a polymeric material. A through circular hole (20) of the element is taken out of the element (10), and several grooves (21) are made in the first sheet. After heating a pressing force is applied to the first sheet of metal foil for forming the sheets so that the bottom surface of the element corresponds to an inclination providing a correct slope, simultaneously the edges of the circular hole are bent so that a tubular part is formed for connection to the floor drain. The grooves of the sheet allow the polymeric material to flow, which will increase the formability of the element, and also tensions of the element will be reduced. A method uses the manufactured device for casting a slope with a correct inclination toward a floor drain.
