FIG. 4 is a schematic perspective view of a column-forming mold having a level adjusting function of the present invention in which a level adjusting tool 1 is provided near the lower edge of a column-forming mold 2 having a substantially cylindrical shape. In the figure, four level adjusters 1 are mounted near the lower edge of the column forming mold 2. The column forming mold 2 may have any of a substantially cylindrical shape as shown in the figure, for example, a circular or elliptical shape, a substantially prismatic shape, or a polygonal prism shape. There is no particular limitation as long as it can be formed.

FIG. 5 is a cross-sectional view of a main part of the details of mounting the level adjuster 1. As shown in FIG. In the figure, 4 is the ground, 3
Indicates soil concrete on the ground 4. The column-forming formwork with a level adjustment function of the present invention is a concrete
Above is fixed by nails 5 via an anchor plate 10. On the other hand, the column forming mold 2 is adhesively fixed to the outer peripheral surface of the freely rotatable bracket member 50,
The height of the column forming mold 2 can be arbitrarily adjusted by moving the entire column forming mold 2 up and down using the rotating plate 40.

After adjusting the height in this manner, concrete is poured into the space 6 to form a column serving as a foundation of a house. An example of the foundation of the house constructed in FIG. 6 is shown in a sectional view of a main part. In the figure, reference numeral 4 denotes the ground, 3 denotes soil concrete on the ground 4, 8 denotes a cloth foundation, and 7 denotes a column using the column forming formwork with a level adjusting function of the present invention. In the present invention, since the level can be accurately adjusted so that the upper edge surface of the cloth foundation 3 and the upper edge surface of the column are aligned, the base 9 placed on these foundations can be horizontally constructed. it can.

As described above, according to the level adjuster of the present invention, the moving member has the above-described female screw portion on the inner peripheral surface and the substantially cylindrical moving portion main body having the flange portion on the upper edge. ,
A rotating plate fixed to a lower portion of the outer peripheral surface of the moving unit main body, and a freely rotatable bracket member positioned above the rotating plate and provided with a step on its upper edge so as not to be detached by the flange of the moving unit main body Therefore, it is easy to adjust the level, which is troublesome, and the horizontal level can be easily adjusted to within 2 mm.

Further, the column-forming formwork with the level-adjusting function provided with the level-adjusting tool at the lower edge of the column-forming formwork is provided so that a base, a large-scale drawing, etc. can be horizontally installed. Since the height of the upper edge end face can be easily adjusted to the height of the upper edge end face of the outer peripheral fabric base, it is easy to adjust these levels, which is troublesome.
It can be easily adjusted to within mm.

Therefore, as compared with the conventional whole fabric base structure in which the outer and inner partitions are continuously formed by the fabric foundation, the superior function and the like as compared with the whole fabric base structure are the ventilation property of the underfloor space. Since there is no damp stagnation and mold and corrosion are less likely to occur, the durability of the upper structure can be improved, and the underfloor space is widened. Maintenance can be facilitated. In addition, since the amount of formwork and concrete used for the foundation can be reduced, construction can be simplified,
Since the cost can be reduced, it is possible to easily construct a basic structure such as a wooden building and other houses having excellent functions and cost.
