BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable support insert for a deck plate suitable for suspending a cable on the lower surface of the deck plate.

[0002]

2. Description of the Related Art A conventional cable support insert for a deck plate is constructed by inserting the insert from the top surface of the deck plate into an insert mounting hole formed in the deck plate and suspending it from the bottom surface of the deck plate after placing concrete. The metal fittings and hanging bolts are attached, and the specified cables are supported on these hanging hardware and hanging bolts (see No. Shokai 60-83105).

On the other hand, in wiring work in apartments and condominiums, since the space from the ceiling slab surface to the ceiling is generally small, the area near the ceiling slab surface should be as close as possible.
It is desirable to wire the F cable, etc. by prior construction. Therefore, the applicant of the present application has previously proposed a cable suspension insert capable of supporting a cable at a position close to the ceiling slab surface (see Japanese Utility Model Publication No. 1-86428). This cable suspension insert is provided with a suspension part on the lower surface of the suspension body through which a binding tool such as a so-called vinyl band or nylon band can be inserted, and the cable to be suspended is tightened to this suspension part. It is something.

[0004]

[Problems to be Solved by the Invention] However, in the conventional cable support insert for deck plate, the cable is supported after the hanging metal fittings are attached to the insert.
There was no choice but to support the cable at a position away from the ceiling slab surface, and this wiring hindered the subsequent construction work. Moreover, the work of installing the hanging metal fittings made the wiring work more troublesome.

Further, a cable suspension insert capable of supporting a cable at a position close to a ceiling slab surface is
Due to its structure, it is used for wooden floor formwork and cannot be mounted on deck plates.

Therefore, the present invention was devised to eliminate the above-mentioned inconvenience, and wiring can be made as close as possible to the ceiling slab surface using the deck plate, and wiring on the deck plate is possible. It is an object of the present invention to provide a cable support insert for a deck plate that can simplify the construction work.

[0007]

In order to achieve the above-mentioned object, the present invention provides a suspension portion 1 which is inserted from the upper surface of the deck plate P in a through hole P1 formed in the deck plate P. Then, an engaging portion 2 that engages around the insertion hole P1 is provided at the upper end of the suspension portion 1, and the suspension portion 1 and the engagement portion 2 form an insert. Furthermore, the suspension part 1 penetrates the insertion hole 1A into which the binding material S or the cable Q having a predetermined diameter can be laterally inserted. Further, a mark 2A indicating the wiring direction of the cable Q is provided on the upper surface of the locking portion 2.

[0008]

According to this invention, the suspension portion 1 projects from the lower surface of the deck plate P, and the locking portion 2 locks on the upper surface of the deck plate P.

Then, the binding material S is inserted into the insertion hole 1A of the suspension portion 1.
Is inserted to bind the cables Q, or the cables Q are directly inserted into the insertion holes 1A to support the cables Q. At this time, the wiring direction of the cable Q on the lower surface of the deck plate P can be confirmed on the upper surface of the deck plate P by the mark 2A of the locking portion 2.

[0010]

Embodiments of the present invention will be described in detail below with reference to the drawings.

Reference numeral P shown in the drawing is a deck plate P used as a waste formwork for slab construction. The deck plate P has a through hole P1 for inserting an insert, which is punched at a predetermined position in advance. When the through hole P1 is punched, a large punch-like shape is used in which the through hole P1 is punched out by using its own weight. It is formed using a dedicated tool.

The insert of the present invention comprises a suspending portion 1 to be inserted into the through hole P1 and a locking portion 2 to be locked around the through hole P1 (see FIG. 1). The suspension part 1 shown in the drawing has a flattened bottom end so that it can be easily inserted from the upper surface of the deck plate P. Then, an insertion hole 1A through which the binding material S or the cable Q having a predetermined diameter is laterally inserted is passed through the flat portion. In the suspension unit 1 shown in FIG. 1, the binding material S is inserted into the insertion hole 1A, and the binding material S is used for the cable Q.
Is locked. Further, the suspension part 1 shown in FIG. 4 has a large insertion hole 1A, and the cable Q is directly inserted into the insertion hole 1A.
The cable Q is locked by inserting the cable. Further, the shaft portion of the suspension portion 1 which is in contact with the through hole P1 of the deck plate P is formed thick so as to be forcibly fitted into the through hole P1 to prevent the suspension portion 1 from coming off.

A mark indicating the wiring direction of the cable Q
2A is provided on the upper surface of the locking portion 2. This mark 2A is
Since the wiring direction of the bull Q is shown, as shown in FIG. 1 and FIG.
In the type in which the binding material S is inserted into the insertion hole 1A,
The directions of the through hole 1A and the mark 2A do not match. Also, FIG.
And, as shown in FIG. 4, insert the cable Q directly into the insertion hole 1A.
In the case of the type that does, the insertion hole 1A and the mark 2A
The orientation will be the same. Thus, the upper surface of the locking portion 2
Mark 2A indicates the wiring direction of the cable Q to be wired.
Is formed .

[0014]

The present invention achieves the original purpose by being configured as described above.

That is, a suspending portion 1 which is inserted from the upper surface of the deck plate P is provided in a through hole P1 formed in the deck plate P, and a binding material S or a cable Q having a predetermined diameter is laterally provided in the suspending portion 1. By penetrating through the insertion hole 1A that can be inserted, it becomes possible to wire the deck plate P as close to the ceiling slab surface as possible.

In addition, by providing a mark 2A indicating the wiring direction of the cable Q on the upper surface of the locking portion 2 which is locked around the insertion hole P1, the insert of this invention is mounted on the deck plate.
Check the wiring direction of the cable Q at a glance when installing on P
Can be installed while working, so work on the deck plate P
Can be performed reliably and easily .

As described above, according to the present invention, it is possible to wire as close as possible to the ceiling slab surface using the deck plate, and the wiring work can be simplified to ensure the work on the deck plate. And easy to do
It has various practically useful effects such as being able to do so .
