SUPPORTING ASSEMBLY OF SHEATH TUBE OF FORM FOR SEGMENT OR THE LIKE

Japanese Patent JP3558791

B2

PROBLEM TO BE SOLVED: To rapidly and simply mount a sheath tube in a form in a predetermined state by bringing a seating plate of the tube into close contact with a base surface of a support shaft without regulating a length of the tube.
SOLUTION: The sheath tube 1 is engaged at both ends with support shafts 21, 22, and installed between side plates 12 and 13 or between the plate 12 and end plates 14, 15. In this mounting state, seating plates 23 of the tubes 1, 2 are brought into close contact with a base surface 21c by means of attracting action of a magnet 26 to hold its state. Accordingly, the tubes 1, 2 are supported in a predetermined state without generating a gap between the plate 23 and the base surface 21c of the shaft 21, and embedded always in a correct state in placed concrete. Since length regulations of the tubes 1, 2 are not required, mounting operations of the tubes 1, 2 in a form can be efficiently conducted.
