Description

[Detailed Description of the Invention] Technical Field This invention relates to a support for a pile pile that is attached to a rod-shaped pile body so that its position can be adjusted in the longitudinal direction and circumferential direction of the pile body.

BACKGROUND TECHNOLOGY Generally, when constructing a foundation for a house, as shown in Fig. 1, after pouring a base part 1 of foundation concrete, a temporary framework for a cloth foundation is installed on top of the base part 1. First, in order to center the top surface of the base part 1 and determine the horizontal position,
A so-called mizuori method is performed. When using the conventional method of applying water, the first and second
As shown in the figure, the base part 1 of the foundation concrete
After driving the pile bodies 2 made of iron pipes at appropriate positions on the outside of the corners and the outside of the edges of The cylindrical support 4 of 3 and 3a is inserted into the pile body 2, and the support 4 is fixed at the mark position on the pile body 2 with screws 5. Then, with the punched board 8 placed on the punched board receiver 7 of each punched board support piece 6, the punched board 8 is held between the end of the screw 9 and the outer peripheral surface of the support 4, and the punched board 8 is 8 threads between 8 boards
There is one in which a is stretched.

However, in this conventional pile, the pile body 2 is held between the end of the screw 5 and the inner surface of the support 4 to fix the punched plate support 3 to the pile body 2, so that There are problems in that the plate support 3 cannot be firmly fixed and the pile body 2 may be damaged. That is, in this conventional configuration, the tip of the screw 5 directly contacts the pile body 2, and the stronger the tightening, the more the outer peripheral surface of the pile body 2 is damaged by the tip of the screw 5. And the pile body 2
As the number of times the pile body 2 is used increases, the number of unevenness and scratches on the pile body 2 increases. When tightening the screw 5 against the pile body 2, if the uneven scratches are close to each other, if the tip of the screw 5 that was supposed to be tightened enters the groove of the scratch, the tightening force of the screw 5 will be weakened. , there is a problem that the plate support 3 may come off. In order to eliminate such a problem, it is necessary to selectively attach it to the outer circumferential surface of the pile body 2 which is not damaged, but the fixing position of the peg board support 3 is very restricted. . In addition, since the punched plate support piece 6 is welded and fixed with its base end surface in contact with the outer surface of the support 4, its positioning etc. are especially difficult when manufacturing the corner punched plate support 3a. This becomes troublesome, and furthermore, since the punching board support piece 6 and the punching board receiver 7 are separate parts, there is a drawback that the manufacturing and assembly cost increases.
