Description

[Detailed Description of the Invention] The present invention relates to an improvement of a temporary fixing device used when fixing an embedded box to a temporary concrete pouring frame.

When embedding an embedded box into a concrete wall using a conventional temporary fixing device, as shown in Figure 1, screw the temporary shielding plate 2 installed to close the front opening of the embedded box 1. Hole 5 provided in the temporary concrete pouring frame 4 to hole 3
The temporary shielding plate 2 and the embedded box 1 were fixed in close contact with the temporary concrete pouring frame 4 by screwing bolts 6 passing through them.

However, in the case of this temporary fixing device, when the bolts 6 are rotated when the temporary shielding plate 2 is brought into close contact with the temporary concrete pouring frame 4, the embedded box 1 may rotate along with the rotation.
Or since it does not rotate, is the embedded box 1 tilted at an angle θ with respect to the center line A as shown in Figure 2 from the outside of the concrete pouring frame, or is it attached directly? could not be confirmed.

For this reason, there was a drawback in that it was not possible to tell whether the embedded box was installed correctly or at an angle until after concrete pouring was completed and the temporary concrete pouring frame was removed.

The present invention was developed in view of the above points, and its purpose is to operate the embedded box from outside the temporary concrete pouring frame when attaching the buried box to the temporary concrete pouring frame. The purpose of the present invention is to provide a device for temporarily fixing an embedded box.

The temporary fixing device for the embedded box will be explained below based on FIG. 3 showing an embodiment of the present invention. It is a box-shaped body, and a part of the opening edge is bent inward to provide screw holes 9, 9.

Reference numeral 10 denotes a temporary shielding plate, which is formed in the shape of a plate with a size slightly larger than the opening 8 of the embedded box 7, and has a conical (or pyramidal-shaped) recess in the back approximately in the center thereof. A conical portion 11 is provided, and a rectangular connecting hole 12 is formed at the tip of the conical portion 11.

Reference numeral 13 denotes a fixing metal fitting, with a screw 14 formed on the upper part, and a rectangular part 1 on the lower side to be inserted into the connection hole 12 of the temporary shielding plate.
5 is formed.

A stopper 16 that rotates in only one direction is provided at the tip of the square portion 15.

In order to attach the embedded box to the concrete pouring board frame as shown in FIG. 4, the electrical conduit 17 is connected to the embedded box 7 to which the temporary shielding plate 10 is attached.

After the concrete pouring board frames 18° 18 are assembled, the embedded box I is lowered between the concrete pouring board frames 18 and 18, and the box I is drilled at a predetermined position in the temporary concrete pouring frame 18. Stop at the position of the hole 19.

Next, insert the fixing fitting 13 into the connecting hole 12 from the outside of the hole 19 as shown in FIG. 5, and after the stopper 16 at the tip thereof rotates as shown in FIG. 6, it is fixed as shown in FIG. Pull back the metal fitting 13 and the stopper 16 will fit into the connecting hole 12.
It is tightened with a nut 20 from the outside of the temporary concrete pouring frame 18 without coming off.

At that time, since the rectangular portion 15 of the fixing bracket 13 and the connection hole 12 of the temporary shielding plate 10 are both square shaped, by rotating the fixing bracket 13, the temporary shielding plate 10 and the embedded box 7 are rotated at the same time. .

Therefore, if the embedded box γ is tilted diagonally, the inclination of the embedded box 7 can be easily corrected by rotating the fixture 13.

As shown in FIG. 8, the connecting hole 12a is made circular in cross section and a notch 12b is provided in a part thereof, and the fixing fitting 13a is also made in a circular cross section so that a stopper 1 is attached to the tip.
6 is provided, and the stopper 16 is connected to the notch 12b.
It is also possible to simultaneously rotate the temporary shielding plate 10a by rotating the fixing fittings 13a.

As described above, the present invention is to install a removable temporary shielding plate from the front side of the buried box so as to close the opening of the buried box, which has an open front side, and to connect the temporary shielding plate to the temporary concrete pouring frame. Connect the tip of the fixing bracket to the inner surface of the temporary concrete pouring frame to the connection hole provided in the temporary shielding plate, and attach it to the temporary shielding plate when rotating the fixing bracket from the outside of the temporary concrete pouring frame. Since the temporary fixing device for the embedded box is made such that the box also rotates, the embedded box can be rotated by rotating the fixing fittings from outside the temporary concrete pouring frame, and the inclination of the embedded box can be corrected. It is possible.
