Further, concrete 31 is placed on the foundation base part 32 along the lower side of the foundation rising panels 11, 11, and after this concrete 31 has hardened, the foundation rising panel holding fittings 28 are removed, and the foundation Construction of the structure 22 is completed.

In the thus constructed foundation structure 22, the foundation base portion 32 and the foundation rising portion 33 are integrally constructed, and there is no need to remove the formwork 24, so this series of construction work is extremely simple. This can be done quickly, thus significantly shortening the construction period.

In the above embodiment, the base panel 13° and the foundation rising panel 11 are each formed into a substantially rectangular shape, but the shape is by no means limited to this, and for example, as shown in FIG. 9(a). 9 in the same figure.
It is also possible to form the upper surface of the birch shown in FIG. 0 in a substantially U-shape, and by combining these forms, it is possible to construct the formwork 24 having various shapes. However, the specific shape of each panel does not matter.

Furthermore, when each panel is made of fiber-containing cement as in this embodiment, the strength of the surface side of the foundation structure 22 is enhanced by the panels, so that the so-called so-called shrinkage of the concrete 31 of the foundation structure 22 is increased. The crack is the base FiM
Although it has the advantage that it does not extend to the surface of the structure 22, the material of each panel is not limited to this.

Furthermore, as in the above embodiment, the base rising panel 11 does not necessarily have a receiving portion 12 for attaching the intermediate holding fitting 25.
There is no need to provide

Further, the configuration such as the shape of the base rising panel holding fittings 28 is not limited to the above embodiment, and is shown in FIG. 10(A).
Both ends 29a, 29a of the metal rod 29 are bent as shown in FIG. One end of the screw material 36 of the turnbuckle 35 may be bent, and a locking portion 37 capable of holding the end of the base rising panel 11 may be provided at the tip thereof. In short,

Further, the base panel 13 disposed facing and in contact with the outer surfaces of the side plates 3, 3 of the fixture 1 is not an essential condition of the present invention, and may be used as necessary.

Further, the work of arranging reinforcement as in the above embodiment is by no means essential to the present invention.

(Effect of the invention) In contrast to the birch described above, the present invention provides a fixing device for forming a foundation base portion of a foundation structure on the ground, and then attaches foundation rising panels facing each other between the fixing devices to form a formwork. , and concrete is poured into the formwork. Therefore, at the same time as the foundation base part is formed in the fixing device, the foundation rising part is connected to the foundation base part between the foundation rising panels. This means that it can be constructed in one piece.

Therefore, compared to the conventional method in which the foundation base part and the foundation upright part were constructed in separate processes, the construction period for the foundation structure could be significantly shortened, which was a particularly remarkable effect.

Furthermore, if a support part for a holder is provided on the foundation rising panel, when the foundation rising panels are mounted facing each other, if the holder is constructed and installed between these receiving parts, this will allow the space between the foundation rising panels to be The spacing is maintained, so even if concrete is poured between the foundation rising panels, the spacing can be maintained constant.

Furthermore, if the receiver for attaching the foundation rising panel to the fixing device is configured to be vertically adjustable, the level between the foundation rising panels mounted facing each other on the fixing device can be adjusted, thereby improving accuracy. This has the advantage that a high foundation structure can be constructed, and subsequent construction work for buildings, etc. can be carried out smoothly.

Furthermore, if a foundation rising panel holder is externally fitted to the ends of the foundation rising panels that are attached to the fixtures facing each other, the spacing between the ends of the foundation rising panels can be maintained constant, thereby preventing concrete pouring. This has the advantage of preventing expansion between foundation rising panels due to construction.
