Other Embodiments In addition, in the adjuster 1 of the present invention, the base member 2
The shape is not limited to that shown in the above embodiments, but may be any shape as long as it has a smooth base receiving surface 7. Further, the first locking portion 23 and the second locking portion 13 may have various configurations in which both can be engaged in a fixed state. In particular, as shown in the embodiment, when the anchor bolt holding part 17 is provided on the base member 2, the holding part 1
7 may be of various configurations to elastically hold the upper end portion of the anchor bolt 19, such as a pair of holding pieces installed at a distance between the base receiving pieces.

(Effects of the invention) The adjuster of the invention consists of a base member having a smooth base receiving surface and a holding member that holds the base member.
By fixing the formwork for forming a cloth foundation at the required height, the foundation mounting surface at the top of the cloth foundation can be configured accurately and efficiently without the need for leveling work as in conventional construction methods. It is possible to reduce construction costs and shorten the construction period.

As shown in the embodiments, when the main body is provided with an anchor bolt holding portion, the following special effects are produced. In other words, in the past, when placing anchor bolts in foundations, the anchor bolts were pushed into the concrete by checking for the appropriate time for the concrete placed between the formwork to harden. It was extremely difficult to predict. By the way, if you misjudge the timing of this pushing, the concrete will harden too much, making it difficult to push in, or the constructed fabric foundation will have uneven strength. Alternatively, the concrete may be too soft and the anchor bolts pushed in may sag or tilt under their own weight. The anchor bolt holding portion holds the upper end portion of the anchor bolt in a stable fixed state until the concrete hardens,
It solves such problems.
