という欠点がある。Conventionally, when it was necessary to continue the foundation upward in this way, as shown in Figure 1, the lower foundation (1a
) Place and assemble the left and right temporary frames (2) (2) on top of the
Concrete was poured into this temporary frame (2) (2), but according to this method, even if you wanted the finished shape of the entire foundation to be vertical, the steps as shown in Figure 2 would not be possible. There was a drawback that this resulted in problems in terms of appearance and delivery.Therefore, as a method to eliminate such drawbacks, the third method
As shown in the figure, the temporary frame (2a) (2) of the lower foundation (1a)
a) Before removing the temporary frame for the upper foundation (3a) (3a
) is placed on top of the lower temporary frame (2a) (2a), and in that state, concrete is poured as shown in ) in the same figure, and after the concrete hardens, the lower temporary frame (2a) is placed. 2
a) A method is used in which (2a) is removed and this process is repeated in sequence. However, although this construction method eliminates the drawback that the entire foundation is shaped like a staircase as shown in Figure 2, it always requires a temporary frame for two levels, and the lower level foundation (1b) is hardened after the upper level foundation (1b) has hardened. There is a drawback that rotation of the temporary frame and workability are deteriorated, such as having to remove the temporary frame (2a).

間が出来ないようにすることが望ましい。(23) is explained in accordance with the construction order of the bending groove formed slightly inward of the support piece (21) in the same manner as in the case of the fixing fitting main body (11). First, as shown in FIG. When constructing the foundation (24a), bury the above-mentioned poles (13) at appropriate intervals with their heads facing down, at approximately the center in the width direction of the upper foundation that is about to be constructed. Let it stick out upwards. In this case, in consideration of the overall thickness of the fixing metal fittings, a recess (25) corresponding to the thickness is formed on the upper surface of the lower foundation (24a), thereby allowing the upper temporary frame and lower foundation (24a' ) It is desirable to prevent any gaps from forming between the two.

２１）（２１）が左右交互となるように配置する。Next, after removing the temporary frame (26) of the lower foundation (24a) in Figure 5, as shown in Figure 6, the bracket body (12) is installed on the upper surface of the lower foundation (24a). Pol) (13
) to protrude beyond the bolt hole (20),
The support piece (21) is brought into contact with the side surface of the lower foundation (24a) (FIG. 7). This is the upper foundation (24b) that will be discussed later.
This is to support the temporary frame (26) for use via the lip (22), and in this embodiment, as shown in FIG.
21) Arrange so that (21) are alternated on the left and right.

The temporary frames used for this do not need to be prepared in two stages as in the conventional construction method shown in Figure 3, and there is no restriction such as removing the lower temporary frame after the upper concrete has hardened, so the rotation of the temporary frames is easy and the work is easy. Good properties.
