Telescopic means having, for example, mechanical jacks and hydraulic jacks 40 having both ends attached to a substantially central portion in the longitudinal direction of each post 38 and the other end of each base 36 so as to be swingable around a horizontal axis. Including.

A plurality of brackets 42 for mounting the first clamp 16 are attached to each post 38 at intervals in the longitudinal direction. Each end of each first clamp 16 and each bracket 42 are provided with holes 44, 46 (FIGS. 3 and 5) that can be aligned with each other, and a pin 48 is inserted into both holes 44, 46. By doing so, the form panels 12, 14 and the first clamp 16 can be held on the bracket 42. A plurality of holes 44 of the first clamp 16 are provided at intervals in the longitudinal direction.

Referring to FIG. 6, the form panels 12, 14 and the clamp 16 are carried toward the installation position of the column bar 10 in a state where both the hydraulic jacks 40 are contracted and the both posts 38 are inclined. . After arriving at the predetermined place, both hydraulic jacks 40 are extended to make both posts 38 vertical. Next, the level of the wheels 32 is adjusted to adjust the level of the lower ends of the form panels 12 and 14.

As shown in FIGS. 7 and 8, after the form panels 12, 14 and the form panels 12, 14 are arranged at positions facing each other, a space between these form panels similar to that of the form panel 14 is provided. Are arranged. This forms a concrete casting space having a substantially rectangular cross section.

Next, another plurality of clamps (second clamps) are arranged around the column bars 10. More specifically, a pair of other clamps (second clamps) 50 similar to the clamps are placed on both ends of the pair of clamps 16 at each level. Next, the first and second clamps 16, 50 are interconnected. Thus, the pair of first clamps are connected to each other via the second clamp. For this interconnection, bolts 52 are passed through both holes 44 at one end of both clamps 16 and 50, and nuts 54
Is screwed. The other end of each of the clamps 16 and 50 has a bolt 56 movable in the longitudinal direction of the clamp.
