The mold fixing tool 1 is provided at the other end of the main body 3, a rod-like main body 3, a mold standing part 5 for fitting a metal mold 50, which will be described later, provided at one end of the main body 3. The fitting part 6 that has been subjected to threading, the clamping part 7 that fits the fitting part 6 into a hole provided in the wooden formwork 30 to be described later, and is held between the wooden formwork 30 using a nut, and the main body part 3 Are connected to or integrally formed with each other, and are configured to include a main body support section 8 that supports the main body section 3 by being applied to the wooden mold 30. The mold fixing tool 1 of the present embodiment is made of iron, and at least a portion exposed from the concrete foundation of the fitting portion 6 and the main body support portion 8 is subjected to rust prevention treatment. Note that the mold fixture 1 may be made of a metal other than iron, or may be made of highly rigid plastic, wood, ceramics, or the like.

  FIG. 3 shows a cross-sectional state of the upright portion of the outer peripheral portion of the solid foundation 100 formed using the solid foundation construction method in which the base portion and the upright concrete according to the embodiment of the present invention are formed by a single concrete shot. Yes. The dotted line part shown in FIG. 3 has shown the concrete reinforcement.

  As shown in FIG. 3, according to the solid foundation construction method according to the present embodiment, the formwork fixture 1 is used to erect the formwork of the upright portion of the outer periphery of the solid foundation, and the formwork is erected The mold fixing tool 10 is used to fix the frame at the upper end. The formwork for forming the outer wall surface of the solid base outer peripheral portion uses a wooden mold 30, and the formwork for forming the inner wall surface of the solid base outer peripheral portion is a metal mold. A frame 50 is used. In addition, a thin plate-shaped mold may be applied to the lower part of the mold fixture 1 to perform concrete casting. By doing in this way, it becomes easy to finish the inside of a standing top cleanly.

  FIG. 4 is a front view of the formwork fixture 20 used in the solid foundation work method according to the embodiment of the present invention, and FIG. 5 is a right side view of the formwork fixture 20. The mold fixing tool 20 is used to form an upright portion inside the outer peripheral portion of the solid foundation. The mold fixing tool 20 includes a base 21, a first mold standing part 25 a for fitting and standing the metal mold 50, a mold standing part 25 having a second mold standing part 25 b, and the base 21.
