PURPOSE: An apparatus for maintaining a gap between concrete molds using bolts integrated with the molds is provided to maintain the gap between the molds by controlling the movement of the molds in all directions. CONSTITUTION: An apparatus for maintaining a gap between concrete molds (1,2) comprises first and second bolts (10,20), a screw rod (30), first and second support plates (40,50), and first and second fastening nuts (60,70). The first and second bolts are supported by the first and second molds. Screw parts are formed in both sides of the screw rod. The first and second bolts are connected to the screw parts of the screw rod. The first and second support plates support the first and second bolts to sleepers (4). The first and second fastening nuts are coupled to the first and second bolts and push the first and second bolts toward the first and second molds through the first and second support plates. |
