材となるため、コスト的に非常に不利である。In the case of the dango system shown in FIG. 7, it takes time for the level mortar 21 to harden, and the work for installing the PC base 3 is inefficient. In the case of the liner system shown in FIG. 8, a plurality of types of liners 22 having different thicknesses are used.
It is necessary to prepare and select the number of sheets to be used and the type thereof, which tends to increase the cost and makes level adjustment work difficult. Especially, fine adjustment is difficult. In the case of the adjuster bolt method of FIG. 9, nuts 23 are provided for each PC foundation 3.
It is necessary to embed the slab and screw the adjuster bolt 24 into it, and these cannot be diverted, that is, the nut 23 and the adjuster bolt 24 are consumable materials, which is very disadvantageous in terms of cost.

により行なわれる。Using the level adjusting jig A having the above structure,
A construction procedure for installing the PC foundation 3 on the site and adjusting the level will be described. First, the laying mortar 13 is laid on the waste concrete 2 at the place where the PC foundation is installed. Simultaneously with or prior to this, the PC foundation 3 is hoisted via, for example, a crane, and the hoisted PC base 3 has a base portion 3
As shown in FIG. 4, the level adjusting jig A is attached to a plurality of positions on both side edges of A. The mounting is performed by loosely fitting the frame body 5 to the side edge of the base portion 3A, and then tightening the tightening bolts 8 screwed into the nuts 7 to fix the base portion 3A of the PC foundation 3 to the seat 9 and the frame body. It is performed by sandwiching it with the lower piece portion 5C of No. 5 of FIG.

Gently lower the PC foundation 3 onto the floor mortar 13,
Install it at the approximate position by aligning the passage with the water thread.
Then, the level adjusting bolt 11 is screwed in to adjust the height level. At this time, for example, an auto level machine is used. Then, while repeatedly measuring the dimensions such as the street, the height, and the distance between the anchor bolts, the adjustment is performed, and
Set the base 3 in place.

図れるという効果がある。In the PC base level adjusting jig of the present invention, a U-shaped jig main body which is loosely fitted to the side edge of the base portion of the PC base is provided on the upper half of the jig main body. Since it can be attached to the base part with a tightening tool and the level can be adjusted with an adjusting bolt screwed into the jig body, the level mortar hardening time unlike the conventional dango method is unnecessary, and the PC base installation In addition to shortening the construction period, fine adjustment is easy and the level adjustment accuracy can be improved. Moreover, the adjustment jig can be easily removed, and the working time can be further shortened. Moreover, since this adjusting jig can be repeatedly used instead of a consumable material, there is an effect that the construction cost can be reduced.
