を特徴とする。Means for Solving the Problems In order to achieve the above object, in the present invention, the lower end of the support bolt is inserted into a floor plate installed on the ground such as a split stone,
The support bolt is fixed by sandwiching the floor plate with the upper and lower nuts screwed to the support bolt, and in the support metal fitting that supports the mold by the receiver attached to the upper end of the support bolt, to the floor plate portion corresponding to the nut. It is characterized in that a rib having a recess on the back surface side is formed and the nut on the back surface side of the floorboard is housed in the rib so as not to protrude from the rib.

がないといった利点がある。First, as in the conventional case, the lower ends of the support bolts (3) and (3) are inserted by penetrating the lower end horizontal portion of the cover plate (2) and the floor plate (1). Then, at this lower end portion, by the nut (4) on the upper side of the floor plate (1), that is, the cover plate (2) and the nut (5) on the back side of the floor plate (1), these floor plate (1) and cover plate (2) ) Is fixed so that it is sandwiched. At this time, as shown in FIG. 2, the floor plate (1) is provided with a rib (21) having a trapezoidal cross section in which the back surface is recessed upward at a portion corresponding to the nut (5) on the back surface side. The nut (5) on the back side is housed in the recess (22) formed by (21). At this time, rib (21)
Is deeper than at least the nut (5), so that the nut (5) is housed so as not to project beyond the floor plate (1). Further, when the lower end of the support bolt (3) projects below the nut (5), the depth of the rib recess (22) should be smaller than the projecting length of the support bolt (3). It is desirable to make it large. However, the diameter of the support bolt (3) is smaller than that of the nut (5), and even if this is not the case, that is, even if the lower end of the support bolt (3) is projected, the floor plate (1) can be stabilized. It is possible to install. Also, if the width l of the ceiling of the recess (22) on the back side formed by the rib (21) is made smaller than the maximum diameter of the nut (5), the nut (4) on the upper side is rotated. This has the advantage that the nut (5) on the back side does not rotate during operation.

しないように支持させている。Next, a receiver (6) for supporting the rising formwork (11)
In the same manner as described above, the upper part of the upper part is provided with the protruding piece (13) for preventing the rising formwork (11) from moving outward and the other locking piece (20) on the outer side thereof. In addition, from the outer end of the slit (7) (7) for inserting each support bolt (3), another projecting piece (23) is provided.
(23) Cut and raised to form these inner and outer protrusions (13)
The rising formwork (11) is supported by the (23) so as not to move inward and outward.

And the base formwork (12) is supported, and the rising formwork (11) has the inner and outer projecting pieces (13) (2) as described above.
3) supported by and on the outside of it, the longitudinal stripes (2
The upper end of the wire mesh formwork (26) consisting of 4) and the horizontal bar (25) is attached to the engaging piece (20) by engaging it, and is made of an inexpensive material such as waste plastic or plastic cardboard on the outside. A disposable base formwork (12) is installed. In this way, with the stand-up formwork (11) and the base formwork (12) installed, the base formwork (12)
After backfilling (27) so as not to float, concrete is placed from above the rising formwork (11) (11) to construct the foundation.

きる。As described above, according to the present invention, in order to fix the support bolt to the floor plate, the nut screwed to the lower end of the support bolt is
Since the nut is housed in the concave portion of the rib formed on the floor plate, the nut does not project to the back surface side of the floor plate and can be stably installed even when the floor plate is installed on a split stone.
Then, the rib itself has an effect of reinforcing the strength of the base plate, and the base plate has only a slight insertion hole for the support bolt formed in the rib portion.
The strength of the floor plate does not decrease. Further, since the formwork support of the present invention can be disassembled into a receiving plate, a supporting bolt, a floor plate, a nut, etc., it can be compacted when stored or transported.
