Then, the fixed end 111 of the scaffold installation beam 110 and the fixed end of the cliff side of the variable support 130 are respectively coupled to the foundation construction part 120 to be fixed to the cliff 2 .

Hereinafter, the basic construction unit 120 will be described with reference to FIGS. 4 to 10 .

Figure 4 is an enlarged view showing the basic construction part of the small island according to the present invention, Figure 5 is an enlarged view showing the base plate coupling structure of the basic construction part according to the present invention, Figures 6 and 7 are the present invention It is an exemplary view showing before and after the operation of the wedge operation part of the foundation construction part according to.

The basic construction part 120 as shown in FIGS. 4 to 7 is largely composed of a base plate 121 , an anchor bolt 122 , and a wedge operation part 123 .

The base plate 121 is made of a metal plate body installed so as to face the upper surface of the footrest installation beam 110 or the fixed end 111 of the variable support 130 is coupled to the lower surface of the cliff (2).

At this time, in the center of the base plate 121 , a hinge coupling part is formed in which the fixed end 111 of the footrest installation beam 110 or the variable support 130 is hinged in a rotatable state, and the four corners of the base plate 121 . A through hole through which the anchor bolt 122 passes is formed in the part.

And, the anchor bolt 122, one side is charged and fixed to the installation hole 2a perforated in the cliff 2, and the other side is to be fixed to the cliff by bolting/nut coupling the base plate 121 to it.

In the configuration of the anchor bolt 122, a thread is formed on the outer surface of the bolt body 1221 extending in the longitudinal direction to be charged into the installation hole 2a of the cliff, and a work tool is installed at the rear end of the bolt body 1221. A chamfered key coupling portion 1222 is formed to transmit the rotational force using it.

A position adjusting nut 1223 is spirally coupled to the bolt body 1221 in front of the key coupling portion 1222, and the base plate 121 is fitted between the position adjusting nut 1223 and the bolt body so as to be fixedly coupled. The position fixing nut 1224 is spirally coupled to 1221).

At this time, the fixing position of the base plate 121 can be adjusted by loosening or tightening the position adjusting nut 1223 and the position fixing nut 1224 . For example, the base plate 121 is preferably installed in close contact with the cliff 2 as much as possible in a parallel state, and the position adjusting nut 1223 and the position fixing nut 1224 are located at four corners of the base plate 121 . ) by adjusting the height of each corner of the base plate 121 through a loosening or tightening operation, close installation is possible.

In addition, a conical cam 1225 is formed at the tip of the bolt body 1221 , and the conical cam 1225 is formed in a conical shape with a diameter gradually decreasing from the tip of the bolt body 1221 .
