Abstract

PROBLEM TO BE SOLVED: To carry out the post-treatment of a power supply cable easily by a method wherein a cap which is driven into the bottom end part of the vertical cylinder of a socket main part and made of synthetic resin and nails which are inserted through the nail holes of the socket main part and driven into a floor frame and made of synthetic resin are provided. SOLUTION: A through-hole 1 and a punch-through cover 9 are formed in parallel in the top plate 2 of the vertical cylinder 3 of the synthetic resin socket main part 6 of a power supply cable socket (a). The inner diameter of the lower end part of the vertical cylinder 3 is a little enlarged and protruding parts 4 are formed integrally on both the outer sides of the lower part of the vertical cylinder 3. Vertical nail holes 5 are formed in both the protruding parts 4. Synthetic resin nails 8 are inserted into the nail holes 5 and driven into a floor frame and, further, a synthetic resin cap 7 which is tapered 11 so as to reduce the diameter of the upper part is driven into the bottom end part of the vertical cylinder 3 of the socket main part 6. With this constitution, the post-treatment of a power supply cable can be carried out easily and simply without spoiling the appearance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary power cable socket which saves post-processing of a temporary power cable used for lighting, power and the like for construction work of a building.

[0002]

2. Description of the Related Art Conventional temporary power cables of this kind are:
As shown in FIG. 9, the power cable (a) is inserted from the upper part into the through hole (c) of the floor formwork (b) and hangs down, and the outlet (d) at the tip of the power cable (a) is connected to the lower floor. It is used as a power source for lighting and power for work.

Then, concrete is cast on the floor formwork (b) to construct a concrete floor (e). On the other hand, when work on the lower floor is completed, as shown in FIG.
After removing, remove the power cable (a) around the lower part of the concrete floor (e) and cut the power cable (a) with a nipper etc. in the hanging recess.
After that, the recess is filled with mortar (f) to perform post-processing of the power cable (b).

[0004]

In the post-processing of the above-mentioned conventional temporary power cable,

(1) Since the concrete floor is suspended from below, the suspension operation is difficult and inefficient, and is unsanitary.

(2) Since the mortar is also filled from below in the hanging recess, the work is difficult, requires a lot of labor and time, is troublesome, and the workability is poor.

(3) If the hanging and the cutting of the power cable are performed delicately, the power cable hangs down and is exposed below the skeleton to deteriorate the appearance.

[0008]

SUMMARY OF THE INVENTION According to the present invention, a power cable socket is used, and after the work is completed, the power cable is cut off and the socket cap is driven in to perform post-processing of the power cable. It is an object of the present invention to provide a temporary power cable socket which is easy to operate, can save labor, and does not impair the appearance.

That is, a projecting portion (4) is integrally formed outside a vertical cylinder (3) having a top plate (2) provided with a through hole (1) through which a power cable (b) is inserted. A socket body (6) made of synthetic resin provided with a vertical nail hole (5) in the protruding part (4), and a synthetic resin punched into the lower end of the socket body (6) in the vertical tube (3). A temporary power cable socket (a) is formed by a cap (7) and a synthetic resin nail (8) inserted into the nail hole (5) of the socket body (6) and driven into the floor form (A). The purpose of the system is to make the post-processing of the power cable easy and easy to operate and to save labor.
The power cable was inserted into the socket body using a power cable socket, and after the work was completed, the power cable was cut and a cap was driven into the socket body.

[0010]

1 to 8 show an embodiment of the present invention. The structure will be described with reference to the drawings. (A) shows a temporary power cable socket, and (6) shows a power cable socket (a). A) a cylindrical body having a top plate (2) in which a through hole (1) and a punchable lid (9) are juxtaposed; An overhang (4) is integrally formed on both sides of the lower part outwardly, and a vertical nail hole (5) is provided in the overhang (4).

(7) is a dish-shaped cap made of synthetic resin, and the upper part of the outer peripheral surface of the dish-shaped cap (7) is formed with a taper (11) having a small diameter at a slightly upper portion. (8) is a nail made of synthetic resin.

(B) is a power cable, and (12) is an outlet provided at the end of the power cable (b).

(A) is a floor form, (13) is a floor form (A)
(B) is a concrete floor.

The operation will be described. As shown in FIG. 7, the socket body (6) is placed on the floor form (A) facing the through hole (13) of the floor form (A), and the nail (8) is attached to the socket body (6). Floor formwork (A)
To fix the socket body (6) to the floor formwork (A).

After that, the power cable (b) is inserted from the upper part into the through hole (1) of the socket body (6) and hangs down. An outlet (12) is attached to the lower end of the power cable (b) and the outlet (12) is attached. 12) is used as a power source for lighting and power for work on the lower floor.

On the other hand, concrete is cast on the floor form (A) to construct a concrete floor (B).

After the concrete on the concrete floor (B) has hardened and the work on the lower floor has been completed, the floor form (A) is removed as shown in FIG. 8 and the nails (8) made of synthetic resin are removed. The operator breaks off the lower protrusion with a hammer or the like.

Next, the vertical cylinder (3) of the socket body (6)
Then, the power cable (b) is cut by a nipper or the like, and then a cap (7) is driven into the large-diameter (10) at the lower end in the vertical tube (3) to perform post-processing of the power cable (b).

When two power cables (b) are required at one place due to a temporary site, the socket body (6)
By punching out the lid (9) of the socket body (6)
When two power holes (1) are formed in the two holes (1) and the power cable (b) is inserted into each of the two holes (1) and the same operation is performed as described above, two power cables ( b) can be installed hanging.

After the work on the lower floor is completed, the two power cables (b) are cut off in the vertical cylinder (3) of the socket body (6) in the same manner as described above to cut the power supply cable. When the cap (7) is driven into the large-diameter portion (10) at the lower end, post-processing of the two power cables (b) can be performed.

[0021]

The temporary power cable socket of the present invention has the following advantages.

(1) Since the socket body of the power cable socket is simply nailed on the floor formwork, the socket body can be easily, quickly and firmly mounted.

(2) The post-processing of the power cable is performed by cutting the power cable in the vertical cylinder of the socket body, driving a cap into the lower end of the vertical cylinder, and breaking off the lower protrusion of the nail. Therefore,

(A) The post-processing operation of the power cable is easy, and it can be performed quickly to save labor.

(B) Since the nail is made of synthetic resin, the downward projecting portion of the nail can be easily broken off by a worker with a hammer or the like.

(C) Since the power cable is not exposed or the post-processed portion of the power cable does not protrude below the body surface, the appearance is not spoiled.

(2) Since the socket body, cap and nail of the power cable socket are all made of synthetic resin,
It can be mass-produced easily and inexpensively.
