ABSTRACT:
A flexible partitioning member for concrete slab is disclosed, and this partitioning member divides the area (where the concrete slab is to be formed) into a plurality of small areas. The conventional partitioning members are made of wooden material, and can be used only for a horizontal concrete slab. The partitioning member according to the present invention is made by extruding a synthetic resin. The partitioning member includes a main body and a cap, and the cap is detached after the curing of the concrete slab. Into the space which is formed by detaching the cap, a sealing material is filled, so that rainwater cannot intrude into the concrete slab. Further, an inclined cutting line is provided, so that an extra portion can be detached, and that the partitioning member in this case can be used in an inclined concrete slab. In this case, the rainwater is better drained.
