Abstract: A gang form system is provided to move a gang form unit easily at a certain distance from one side of a wall and to locate a gang form unit to the preset location. A gang form system comprises a gang form unit(100) ascending by getting supplied with lifting force from the upper part of many stories and comprising an upper gang form unit(110) composed of first vertical bars(111), first horizontal bars(112) and first support plates(113) and a lower gang form unit(120) composed of second vertical bars(121), second horizontal bars(122) and second support plates(123) and coupled to the bottom of the upper gang form unit to be separable, a guide rail unit(200) locating the gang form unit at a certain distance along the longitudinal direction of a wall(10) by ascending the gang form unit and comprising many rails(210) coupled to one side of the lower gang form unit along the longitudinal direction of the wall, guide devices(220) arranged on the wall at regular intervals to guide the movement of the rails and a stopping device stopping the movement of the rails at regular intervals, a spacer unit(300) installed to one side of the gang form unit and spacing out the gang form unit from the wall and rotating to change the location by getting supplied with the lifting force and comprising a first support(310) coupled to one side of the rail, a second support(320) hinged to the top of the first support, many sliding brackets(350) guiding the horizontal movement of the second support and provided with a sliding hole fitted with a sliding projection projected to the top of the rail and formed on the outside of the second support, a third support(330) hinged to the top of the second support and coupled to one side of the upper gang form unit and a fourth support(340) coupled to one side of the upper gang form unit and hinged to the top of the third support, many wall rollers(400) provided to the bottom of the lower gang form unit and contacted to the outside of the wall to roll over to keep the bottom of the lower gang form unit not to be bumped into the outside of the wall, a length fixing unit(500) formed on one side of the upper gang form unit, suspended on the top of the wall by ascending the gang form unit along the longitudinal direction of the wall to fix the vertical length for forming the wall and composed of a top fixing member(510) installed to the top of a cover plate(540) installed to cover the longitudinal surface of the wall and a bottom fixing member(520) installed to the bottom of the cover plate to form the vertical length with the top fixing member, lifting bars(610,620) connected with first and second ropes to get supplied with lifting force, a fixing device fixing the lower gang form unit to many spots of the wall and comprising a fixed bracket fixed to the gang form unit and an anchor bolt fixing the fixed bracket and the wall, and a pair of mold frames for wall formation installed to two corners along the direction of the first vertical bars of the upper gang form unit and composed of a first frame, a projection projected from the first frame and a second frame bent at a right angle from the first frame.
