In addition, it has a size that does not hinder work such as inspection.

In this embodiment, the mounting table 11 is configured separately from the accessory device 10 and fixed to the bottom of the accessory device 10, and the storage portion 12 is provided on the bottom surface of the mounting table 11. This storage section 12
It is also possible to adopt a configuration in which the holding body 1 is attached to.

Furthermore, instead of storing the holding body 1 at the bottom of the accessory device 10, a simple method may be adopted in which it is detachably attached directly to the bottom or the like with bolts or the like.

A pair of locking portions 4, 4 are provided on the bottom surface of the storage portion 12.
is provided vertically, and the upper base portion 3 of the holding body 1 is fitted between the locking portions 4, 4.

The clamping body 1 has a base 3 on its upper part, and this base 3
A pair of clamping legs 2 are provided below with a gap 2a and facing each other. This gap 2a is slightly wider than the thickness of the existing pile P and is approximately equal to the surface shape of the pile P, and prevents the clamping legs 2 from wobbling when the accessory device 10 is installed on the pile P. Also, the fifth
In the second embodiment shown in the figure, a fixing device 2b is provided at the lower end of one of the clamping legs 2. The fixing device 2b is composed of a bolt or the like, and stabilizes the clamping body 1 with respect to the pile P by coming into contact with the existing pile P. Further, the base 3 is rotatably supported by the locking parts 4, 4 by a shaft 5, and by removing this shaft 5, the holding body 1 can be attached to and detached from the mounting table 10, etc. .

The mounting position of the holding body 1 can also be at the front and rear ends of the accessory device 10, as shown in FIG. In this case, a configuration may be adopted in which the clamping body 1 can be detachably fixed to the accessory device 10 with bolts 51, or can be rotated 180 degrees by the shaft 51 attached to the accessory device 10.
