【Example】

 1 to 8 show an embodiment of the present invention, FIGS. 1 to 6 show a first embodiment, and FIGS. 7 and 8 show a second embodiment.

It should be noted that the same reference numerals are used for the same mode parts as those of the conventional structure of FIG.

In the first embodiment of FIGS. 1 to 6, reference numeral 11 denotes a support member, in which case a bulge 11b is formed at the tip of a metal shaft 11a, and the tip of the shaft 11a is formed. A female screw portion 12 that can be screwed to the male screw portion 5 of the separator 3 is formed, and a hexagonal nut-shaped locking portion 13 is fixed to the outer end portion of the support member 11 by welding.

Reference numeral 14 denotes a holder, and in this case, it is welded to the outer peripheral surface of the metal cylindrical portion 14a which is rotatably inserted in the outer peripheral surface of the support member 11 in a loose state. It is composed of two metal blade-shaped holding parts 15, and each holding part 15 is formed with a locking recess 15a.

Reference numeral 16 denotes a wedge member, which in this case is formed by bending a plate material into a substantially U shape and has two widths B ₁ and B ₂ , and a side surface having a wide width B ₁ . Is used as the pressure contact surface 16a, and the split pin 17 is inserted into the open end.

Reference numeral 18 is a disc spring washer, and the disc spring washer 18 elastically presses the holding body 14 when holding the flap material 4 so that the holding portion 15 elastically contacts the flap material 4 and is held by this frictional action. The body 14 is designed so that it cannot be rotated by play.

Reference numeral 19 denotes an abutting member, which in this case is formed on the outer peripheral surface of the cylindrical portion 14 a of the holding body 14 by welding so as to protrude, and has a tip end on a disc that can abut the outer surface of the dam plate 2. The contact seat 19a is welded.

Since the first embodiment has the above-described structure, the cylindrical portion 14a of the holding body 14 is rotatably inserted into the shaft member 11a of the support member 11 in a loose state as shown in FIG. The disc spring washer 18 is inserted in the above, the locking portion 13 is fixed to the outer end of the shaft member 11a by welding, and the wedge member 16 is interposed between the locking portion 13 and the cylindrical portion 14a of the holding body 14. Then, the split pin 17 is inserted into the open end of the wedge member 16, and as a result, a finished product of the frame material holding metal fitting for the steel pipe is assembled as shown in FIG.

Therefore, for example, as shown in FIG. 3, first, the female screw portion 12 of the support member 11 is screwed to the male screw portion 5 of the separator 3 to connect and project the support member 11 to the female screw portion 12. The locking part 13 is clamped by a spanner or box wrench and rotated, and at this time, the narrow width B ₂ of the wedge member 16 is positioned between the cylindrical part 14a and the disc spring washer, and the holding body 14 is retracted. In this state, the flap material 4 is longitudinally arranged on the side surface of the barrier plate 2 and then laterally arranged on the flap material 4, and the holding portion 14 is attached to the flap material 4. Are arranged so as to face each other in an orthogonal state, and in this state, the wedge member 16 is hit with a hammer or the like as shown in FIG. 4, and the wider width B ₁ is positioned between the cylindrical portion 14a and the disc spring washer. 14 is advanced by the difference between the width B ₁ and the width B _2, holding member 14 is pressure contact with pressing surface 16a Then, the locking recess 15a of the holding portion 15 is pressed against the side surface of the flap material 4, whereby the disc spring washer 18 is compressed, and if the holding portion 15 is pressed against the flap material 4 via this spring action. The material 4 is held by the barrier plate 2 and the holding portion 15 in a sandwiched state.

When the flap material 4 is removed, the holding portion 15 releases the flap material 4 by loosening and turning the locking portion 13 with a spanner or box wrench. The flap 4 can be removed, and by loosening and rotating the locking portion 13, the entire supporting member 11 can be removed from the separator 3.

Therefore, the locking member 13 is rotated to attach the support member 11 to the separator 3, the flap member 4 is arranged, and then the wedge member 16 is tapped to remove the flap member 4 by the holding portion 15 of the holder 14. The flap material 4 can be released by tightening and holding, and by loosening and turning the locking portion 13, the entire member including the support member 11 can be removed. Workability can be significantly improved.

Further, in this case, since the holding body 14 is in the state of being prevented from coming off due to the locking portion 13 at the end portion of the support member 11, it is convenient to carry and the parts management can be facilitated. Moreover, since the tubular portion 14a is inserted into the support member 11, the bending strength of the support member 11 is also increased.

In this case, the abutting portion 19 a of the abutting member 19 abuts on the outer side surface of the barrier plate 2 in the state where the flap material 4 is held, and by this abutment, the abutting portion 19 a hangs on the holding portion 15 via the flap material 4. The force can be received, the bending of the support member 11 and the holding body 14 can be prevented, and the strength is increased. Further, this abutment allows the holding body 14 to move freely in addition to the action of the locking recess 15a. The rotation can be regulated, the flap member 4 can be prevented from being detached due to the unexpected rotation of the holding body 14, and the safety is improved.

The second embodiment shown in FIGS. 7 and 8 shows another structure, in which the formwork structure has two flaps 4 arranged in the vertical direction first, and then two pieces 4 arranged in the horizontal direction. The above embodiment is applied to the above.

The shapes of the holding body 14 and the holding portion 15 are appropriately changed and designed according to the size of the flap 4, and there is also one holding portion 15.

Although the holding portion 15 is formed by welding, it may be integrally formed with the holding body 14 by another processing means such as die casting, casting or forging.

Further, although the above embodiment is applied to the case where the flap material 4 is first arranged in the vertical direction, it is also applicable to the case where the flap material 4 is arranged first in the horizontal direction.

Further, although the flap 4 is a steel pipe in the above embodiment, it can be applied to a square pipe by changing the shape of the holding portion 15 as it is or changing it.

Further, although the disc spring washer 18 is used in the above embodiment, the number of the disc spring washer 18 may be changed appropriately, and another spring member such as a cylindrical coil vane or urethane rubber may be used instead of the disc spring washer 18. You may use the elastic material.

Further, the separator 3 of the above-described embodiment has a structure in which the male screw portion 5 is projected at the end portion, and therefore the female screw portion 12 is formed on the support member 11 so as to be connectable. Some separators have a structure in which a female screw is engraved at the end thereof. In this case, a male screw portion that can be screwed into the female screw is integrally formed on the support member 11 so as to project therefrom. Alternatively, the support member 11 is left as it is, and a screw rod having one end screwed to the female screw portion 12 and the other end screwed to the female screw of the separator is prepared, and the support member 11 is supported by this screw rod. May be attached to the separator 3.
