FORM FOR CONSTRUCTING CONCRETE STRUCTURE

PROBLEM TO BE SOLVED: To simplify mounting work by placing concrete into partitioned spaces, performing supporting with a column on the rear side of precast concrete(PC) board forming a wall surface after it is solidified, arranging an angle member on the rear side, and placing a wedge between the rear surface of PC board and the column. SOLUTION: On the flattened concrete reinforcement bars are arranged and ready mixed concrete is placed, timbering 10 is assembled on the floor board, and PC boards 20 are arranged form the first stage in order. In this case, the work is carried out in a space where concrete is placed, between the board 20 and the column 12 a wedge is placed through a guide groove of the board 20, and the two 210, 12 are fixed. Then, similarly, other boards 20 and columns 12 are fixed, and the boards 20 are stacked by one lift while concrete is placed by one lift. Accordingly a form is worked by one lift, and after the placement the form is remained as it is to serve as a wall surface of retaining wall.
