The present invention relates to an apparatus for fixing a concrete form for a waterproof jaw, comprising: a polygonal column-shaped support part (10); a skirt part (20); a cutting part (30); and a supporter (40). The polygonal column-shaped support part (10) has a polygonal shape, a hexagonal or octagonal shape, with a section gradually becoming larger from the upper end to the lower end and each surface is divided by ribs (11) formed with a geometrical shape to have insertion grooves (12). The skirt part (20) has a section larger than a lower end of the support part (10), a center recessed upward to the support part (10) with a predetermined depth and opened downward to form a spiral groove (21), and an outer circumferential surface extended downward. The cutting part protrudes from the upper end of the support part (10) to have a diameter smaller than the upper surface of the support part (10) and a predetermined height, has a pin hole (31) of a long shape formed to horizontally pass through the outer circumferential surface with a predetermined height to allow a fixing pin (33) to be inserted thereinto, and has a cutting groove (32) formed on the outer circumferential surface of the pin hole (31). The support part (40) has its upper end coupled to the spiral groove (21) of the skirt part (20) and is coupled to a slab form (50). According to the present invention, a further strong coupling force is secured in comparison with concrete mortar, and the slab form and the form for the waterproof jaw can further easily and rapidly be assembled and disassembled. |
