Support. As such a drainage pipe support device, it is necessary to finely adjust the support position of the drainage pipe in each support device part in order to ensure the flow gradient of drainage.

  As shown in FIG. 22 of Patent Document 1, the above-described drainage pipes are supported on the floor by supporting plate portions at both ends of a pair of half-ring-shaped split supports that support the drainage pipes from above and below. The supporting height of the drainage pipe to be supported is adjusted by supporting the pair of bolt shafts at a predetermined height position via a nut. Therefore, the pair of upper and lower half-ring-shaped split supports are supported by the pair of bolt shafts via a total of four nuts from the upper and lower sides at the support plate portions at both ends thereof.

  For this reason, in order to adjust the support height of the drain pipe, a total of four nuts can be screwed and rotated (the operation of rotating the nut screwed to the bolt and moving it in the axial direction of the bolt). It is necessary and the adjustment is very troublesome. In particular, the screw turning operation of the nut arranged below in each bolt shaft has to be performed in a cramped form that bends the fingertip of the thrusting hand upward. It was troublesome because I could not get it.

  Therefore, in Patent Document 1, of the above-described total of four nuts, two nuts arranged below are improved so that a screw rotation operation can be performed above the nuts. However, since the screw turning operation of the nut is still necessary, it takes time to adjust the position of the support height of the drain pipe.
