Publication No. 4411).

(Problems to be Solved by the Invention) However, there are a large number of types of buried boxes 120, each of which has a different opening size or depth. Furthermore, there are many ways to fix the buried box to the formwork, and it must be equipped with a functional structure that supports these fixing methods. As you can see, there are many types of buried boxes 1
Providing the cylinder body 122, which is one of the methods of fixing to the formwork, on all of the cylinders 20 is not only extremely troublesome, but also has the disadvantage of increasing costs.

In addition, as shown in Fig. 12, the buried box 1
In the conventional method of constructing the supporting member 30 between the cylindrical body 122 and the formwork 40b, if the pressing force applied to the buried box 120 by the supporting member 30 becomes uneven, the cylindrical body 122 and the formwork 40a, the buried box 120 and box cover 110 are deformed and a gap is formed between them.
There is a possibility that concrete may enter the buried box 120 through this gap.

In addition, as shown in FIG.
20 may be fixed to studs 140 or the like, and in this case, in the case of a buried box 120 with a cylindrical body 122 provided on the periphery, the cylindrical body 122 gets in the way, making it difficult to securely fix it to the stud 140. It also has the disadvantage that it cannot be done.

The present invention has been made in consideration of the above-mentioned situation, and its purpose is to provide a box cover for a buried box that can position and fix a general buried box between formwork using a support member, and that has a structure that can prevent the box cover and the buried box from deforming due to the tension of the support member.

(Means for Solving the Problems) The means taken by the present invention to solve the above-mentioned problems are as shown in FIGS. 1 to 11.
``A box cover that is attached to a buried box 20 that is positioned and fixed between opposing formworks 40a and 40b in order to be buried in a concrete wall etc.
A locking part 11 is formed to lock one end of the support member 30 installed between the support member 30 and the other formwork 40b in order to bring it into close contact with the box cover 10. A box cover 1 for a buried box 20, characterized in that a locking body formed so as to be located on a surface is provided on the periphery.
0”.

That is, the present invention makes it possible to position and fix the box cover 10, which is attached to the buried box 20 and which is of a much smaller variety than the buried box 20, between the formworks 40a and 40b using the support member 30, and this box The buried box 20 to which the cover 10 is attached is positioned and fixed between the formworks 40a and 40b.

(Effect of the invention) By adopting the above-mentioned means, the present invention
It has the following effects.

A locking portion 11 that locks one end of a support member 30 installed between the box cover 10 and the other mold 40b in order to bring the box cover 10 into close contact with the other mold 40a.
is provided on the periphery of the box cover 10, so that the box cover 10 can be attached to one of the formworks 40.
The support member 30 is installed between the locking part 11 and the other formwork 40b in close contact with the box cover 10, or the support member 30 is installed between the locking part 11 of the box cover 10 and the formwork 40b. Box cover 10
The buried box 20 to which the box cover 10 is attached can be positioned and fixed between the opposing mold frames 40a and 40b.

Then, the tip of the locking body provided with the locking part 11 is
Since it is formed so as to be located on the same plane as the formwork abutting surface of the box cover 10, when the tip of the locking body comes into contact with the formwork 40a, the formwork abutting surface of the box cover 10 is brought into contact with the formwork. The buried box 20, which is attached to the box cover 10 by contacting the frame 40a and following the frame 40a, is positioned and fixed. Therefore, there is almost no worry that the buried box 20 and box cover 10 will be deformed.
Reliable burying can be expected without concrete intrusion into the burying box 20 due to deformation.

That is, the formwork support member 30 is provided between the formworks 40a,
At 40b, it acts like a poking rod, and its both ends are the parts where the force of poking against the formwork is most likely to be applied. Therefore, the locking part 1
The tip of the locking body with the box cover 10
Since the box cover 10 is formed so as to be located on the same plane as the formwork abutting surface, the box cover 10 is stretched against the formwork on the straight line on which the formwork support member 30 is arranged. This prevents the box cover 10 and the box 10 from being deformed by preventing direct tension from being applied to the box cover 10 and the box 10.

(Example) Hereinafter, the present invention will be described in detail according to an example shown in the drawings.

As shown in FIGS. 1 to 9, the painting allowance cover, which is one of the box covers 10 for the buried box 20 according to the present invention, has tips abutting the formwork 40a at the four corners of its periphery. A cylindrical body 12, which is a locking body into which an end of the support member 30 is fitted, is integrally provided. In this embodiment, the bottom of the cylinder 12, that is, the locking part 11 that locks one end of the support member 30 is connected to the surface (the tip of the cylinder 12) that contacts the formwork 40a of the box cover 10. A predetermined distance is provided between the two. Therefore, as shown in FIGS. 8, 10, and 11, the formwork 40
If the distances between a and 40b are equal, the distance between the formwork 40b on which the support member 30 is constructed and the locking part 11 will be the same, even if the thickness of the buried box 20 and the box cover 10 themselves are different. The supporting members 3 are always at a constant distance and have the same length.
0 can be used.

In this invention, the position of the locking portion 11 is set to the support member 30 when the locking portion 11 is attached to the embedded box 20.
As in this embodiment, the box cover 10 may be attached to the mold 40a.
There is no particular need to provide a predetermined distance between the surface (the tip of the cylindrical body 12) that contacts the box cover 10 and the cylindrical body 12. Also, the number of the cylindrical bodies 12 provided on the box cover 10 is not particularly limited, but it is possible to more reliably attach the buried box 20 to the formwork 40a.
In order to position and fix the plate so as to be in close contact with the plate, it is preferable to provide at least two plates.
In this embodiment, the box cover 10 is a paint edge cover and has an opening formed in advance, but it may be something other than a paint edge cover, or it may be something in which an opening is formed by punching out a part of it after the formwork is removed.

As shown in FIG. 12, in the conventional method of erecting the support member 30 between the buried box 120 and the formwork 40b, the pressing force applied to the buried box 120 by the support member 30 is uneven. If the buried box 120 and the box cover 1
10 is deformed and a gap is formed between the two, and there is a risk that concrete may enter the buried box 120 through this gap. However, in this embodiment, the box cover 1 is
Even if the pressing force applied to the box becomes uneven, the tip of the cylindrical body 12, which is a locking body, comes into contact with the formwork 40a, so there is no fear that the buried box 20 and the box cover 10 will be deformed. There is almost no concrete intrusion into the burial box 20, and reliable burial can be expected.

Next, the buried box 20 to which the box cover 10 for the buried box 20 according to the present invention is attached is shown.
An example of positioning and fixing work will be explained.

First, as shown in FIG.
Four mounting members 50 are fixed with nails 51 to the formwork 40b on the opposite side from the formwork 40a to which the box cover 10 attached to the box cover 10 is closely attached, so as to correspond to the cylindrical body 12 of the box cover 10.

Next, as shown in FIG.
A pedestal 60 into which one end of the support member 30 is fitted is attached to each of the pedestals 60,
One end of the support member 30 is fitted.

Next, as shown in FIG.
The cylindrical body 12 of the box cover 10 attached to the box cover 10 is fitted onto the support member 30 so that the locking portion 11 comes into contact with the support member 30.

Finally, as shown in FIG. 8, by attaching the other formwork 40a closely to the tip of the cylindrical body 12, the buried box 20 is fixed closely to the one formwork 40a. It's getting old. In this example, after forming the concrete wall,
When the formworks 40a and 40b are removed, the mounting member 50 fixed to the formwork 40b is removed together with the formwork 40b, and a hole corresponding to the mounting member 50 is formed in the wall surface, as shown in FIG. This hole can be closed by attaching the lid member 70 to the hole.
Although this embodiment is an example in which the formwork 40a is retrofitted,
Buried box 20 according to the present invention may also be used in other cases.
Needless to say, a box cover 10 for use in the present invention can be applied.

(Effects of the invention) As described above, the buried box equipped with the box cover according to the present invention is a box cover that is attached to a buried box that is positioned and fixed between opposing formworks in order to be buried in a concrete wall, etc. In order to bring the box cover into close contact with one formwork, a locking part is formed to lock one end of the support member installed between the other formwork, and the tip thereof is connected to the mold of the box cover. The feature is that a locking body formed on the periphery is provided on the same surface as the frame abutting surface, which allows the box cover to be locked in close contact with one of the formworks. If a support member is installed between the stop part and the other formwork, or a support member is installed between the stop part of the box cover and the formwork, and the formwork is brought into close contact with the box cover, the box cover A general buried box to which this box cover is attached can be positioned and fixed between opposing formworks.

Furthermore, there is almost no fear that the buried box and box cover will be deformed when tensioned with the support member, and reliable burying can be expected with no concrete intrusion into the buried box due to deformation.
