<p>PURPOSE:To improve quality by constituting a supporting device from a wave- shaped supporting plate which has a recessed part into which a small opening diameter pipe is arranged and is fixed in free contact and separation on a floor and a U-bolt having a ratchet screw which fixes the small opening diameter pipe arranged in the recessed part of a supporting device through a hole for supporting tool formed in a projection part. CONSTITUTION:A wave-shaped supporting plate 8 having uneven parts is fixed on a floor 7 so as to be attached and separated by the embedded metalware 6, etc. A pipe 3 having a small opening diameter is arranged in the recessed part of the wave-shaped supporting plate 8. The small diameter pipe 3 is inserted into a supporting fitting hole 9 of the projection part of the wave- shaped supporting plate 8, and a U-bolt 10 having a ratchet screw is pushed into a fixed member 11. The fixed member 11 is spread by the pushing-in, and the ratchet part 10a is fixed. The loosening of the ratchet bolt 10 can be adjusted by the nut 5 of a screw 12. Accordingly, the quality of the supporting device can be easily improved.</p> |
