Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an electric equipment box set for embedding in a formwork.

(Prior Art) As shown in FIG. 3, a conventional appliance box for embedding in a formwork has one end 49a of a spacer 49 fixed to an outer surface 43a of the bottom of an appliance box body 43 and the spacer 49.
To the other end 49b of. It is configured by forming a male screw portion 51. Then, the electric appliance box 41 is attached to the frame plates 60, 6 for the formwork.
When mounting between 1, the frame plate 61 is formed with a hole 56 for inserting the spacer tip portion 49b, the spacer tip portion 49b is inserted into the insertion hole 56, and the male screw portion 51 is framed. Board 61
Workers screw and tighten nuts 53, 53 from inside and outside of the electric appliance box 41 to attach the electric appliance box 41 between the frame plates 60, 61.

However, in the conventional electric appliance box for embedding in a mold as shown in FIG. 3, the spacer 49 is attached to the frame plate 61 for the mold.
Since it is necessary to form the insertion hole 56 for inserting the male screw portion 51 of the above, there is a problem that the drilling process is troublesome and time is required for that, and it takes a long time to install the electric appliance box 41. . Also, this appliance box 41
There is a problem that a worker needs to carry out the mounting work from the inside and the outside of the frame plate 61 respectively when mounting the electric box on the frame plate 61, and a plurality of workers are required to mount the electric appliance box. In a place where the outside of the frame is narrow, it is difficult for a worker to enter the outside of the frame plate 61 when the nut 53 is screwed into the male screw portion 51 of the spacer 49 from the outside of the frame plate 61, which makes the installation work of the electric appliance box 41 complicated. There is also the problem of becoming.

Can be attached to the inner surface 31a of the frame plate 31 from the inside of the frame plate through the mounting holes 34, 34. The cylindrical members (14A, 14B) and the protrusion 13 may be integrally formed with the pedestal body (9, 10), respectively.

The spacer member 19 is made of synthetic resin and has an appropriate length (for example, 100 m).
m-200mm) hollow hollow bar shape, and the scale 21, 21
Is marked, and the length thereof can be adjusted by cutting at appropriate scales 21, 21 ... according to the distance between the frame plates 30 and 31 for formwork.

Reference numeral 25 in the figure is a sealing material such as paper or vinyl sheet for preventing concrete from entering the electric appliance box 3. The sealing material 25 has an area larger than the opening area of the box, and the outer surface 3a of the bottom of the box 3 is
After the pedestal member 5 is fixed to the box, it is attached to the rim of the box opening.

Next, a method of using the electric instrument box set for embedding in the formwork of the illustrated embodiment will be described. When the electric instrument box set X is assembled to the formwork, a spacer member is previously prepared.
Predetermined scale according to the internal spacing of the frame plate to be assembled 21
Cut and put in the part. Further, one of the pair of base material members 5, 6 is attached to the outer surface 3a of the bottom of the electric appliance box 3 with the bolts 35, 35 ... And the spacer member is inserted into the fitting hole 15A of the base member 5. Insert one end 19a of 19 into
The box 3, the pedestal member 5 on one side, and the spacer member 19 are integrally connected. The box opening 3c is the box 3
After assembling the pedestal member 5 and the pedestal member 5, the lid member is covered with the sealing material 25. Next, the frame plate 31 on one side is erected, and the inner surface of the frame plate 31
The other pedestal member 6 is attached to the predetermined position on the side 31a from the inside of the frame plate 31 with wood screws 36, 36, ..., And then, the space fitting hole 15B of the pedestal member 6 is integrally coupled to the box 3 side. The other end 19b of the member 19 is fitted. Then, the frame plate 30 is erected so that the inner surface 30a of the other frame plate 30 is brought into contact with the opening 3c of the electric equipment box 3 covered with the sealing material 25, and the form is assembled. In this way, this electric appliance box set can be assembled entirely from the inside of the mold, and therefore can be installed by only one operator and only from the inside of the mold. Incidentally, the order of assembling the electric equipment box set is not limited to the above assembling method, and the respective members may be sequentially assembled one by one.

(Effect of the invention) The electric equipment box set for embedding in the mold of the present invention is
As described above, one pedestal member 6 of the pair of pedestal members 5 and 6 may be attached to the inner surface 31a of the frame plate 31 from the inside of the mold, and further other members may be sequentially assembled from the inside of the mold. Therefore, the number of workers can be reduced (can be done by one worker) and can be simplified compared with the case of assembling a conventional electric appliance box for embedding in a form as shown in FIG. Since the mounting work can be carried out and the frame plate does not need to be perforated, the end effect period of the frame plate can be extended, which is a practical effect.
