DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable for supporting a cable by utilizing a groove on the lower surface of a deck plate. A support for suspending a cable is detachably mounted in a groove on a lower surface of the deck plate. It relates to a cable support.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. 4-119503 discloses a technique for laying a cable on the underside of a deck plate by drilling a through hole in the deck plate and supporting the cable with an insert inserted and locked in the through hole. Have been described.

Further, as a fixture utilizing a groove formed on the lower surface of the deck plate, there is a fixture for hanging metal fittings described in Japanese Utility Model Laid-Open No. 4-107313. This fixture uses a fixture inserted into the groove of the deck plate together with the hanging metal fittings.
By rotating the hook by a degree, the hanging fitting is fixed inside the groove.

[0004]

The insert for supporting the cable has the advantage that the cable can be routed to a position near the lower surface of the deck plate. However, the insert for supporting the cable before the concrete is cast on the deck plate. It is necessary to drill through holes in advance, and wiring work to the deck plate after casting concrete is extremely difficult.

Further, since the latter fixture for hanging metal fittings has a structure in which hanging metal fittings for connecting hanging bolts are mounted, even if it is suitable for hanging the hanging bolts, it is preferable to use a cable for hanging. In wiring work, many cables cannot be efficiently routed.

Accordingly, the present invention has been made to solve the above-mentioned problems, and provides a cable support for a deck plate which can efficiently route cables by using grooves on the lower surface of the deck plate. With the goal.

[0007]

According to a first aspect of the present invention, there is provided a cable support mounted in a groove having a narrow opening formed in a lower surface of a deck plate. And a locking portion 1 that is inserted into the groove P1 of the deck plate P and locked inside the narrowed opening,
A crimping piece 2 for crimping the outside of the opening of the groove P1 is provided below the locking portion 1, and a support member 3 for supporting the cable Q is provided below the crimping piece 2. Then, the locking portion 1 and the crimping piece 2 are separately formed on the support member 3 having an upper opening, and the cable Q is inserted into the support member 3 from the divided portion of the locking portion 1 and the crimping piece 2.
Wire.

[0008] Further, the support member 3 of the third means is for removably connecting another cable support 4 to a lower portion of the support member 3.

[0009]

Embodiments of the present invention will be described below.

The cable support of the present invention is mounted on a deck plate P having a groove P1 having a narrowed opening on its lower surface. Therefore, a locking portion 1 inserted into the groove P1 and locked inside the narrowed opening, a crimping piece 2 crimped outside the opening of the groove P1, and a support member 3 supporting the cable Q are provided. (See FIG. 1).

After the locking portion 1 is inserted into the inside of the groove P1,
By turning it 90 degrees, it locks inside the narrowed opening of the groove P1 (see FIG. 2). Therefore, the locking portion 1 is provided in the groove P1.
Is formed so as to be rotatable in the inside of
Is rotated by 90 degrees, an engaging surface 1A that engages with the inside of the narrowed opening of the groove P1 is formed so as to protrude (see FIG. 4).

The crimping piece 2 is provided below the locking portion 1,
Crimping is performed outside the opening of the groove P1 (see FIG. 3). The illustrated crimping piece 2 is formed in a curved shape with a band-shaped plate having elasticity,
At both ends of the groove P1 that are pressed against the outside of the opening, fitting protrusions 2A that fit inside the opening of the groove P1 to prevent rotation of the locking portion 1 are provided (see FIG. 4). By forming the crimping piece 2 in this manner, the elastic force of the crimping piece 2 is crimped to the outside of the opening of the groove P1 to enhance the stability at the time of mounting, and the fitting protrusion 2
Since A is fitted into the opening of the groove P1 to prevent unexpected rotation of the locking portion 1, a reliable locking state is maintained.

The support member 3 is provided below the crimping piece 2, and the cable Q is suspended by the support member 3 (see FIGS. 3 to 5). The illustrated support member 3 is formed in a loop shape, and the cable Q is inserted into the loop. However, the shape of the support member 3 is not limited to the illustrated example.
The well-known support member 3 for suspending the above can be diverted.

At this time, the support member 3 is formed in a loop shape having an open upper portion, and the upper end of the support member 3 is provided with a locking portion 1.
And the crimping piece 2 are formed separately from each other, so that the cable Q
(See FIG. 1). As a result, the cable Q can be inserted into the inside of the support member 3 from the side, and the wiring work can be streamlined. Further, by providing a tapered surface 1B for introducing the cable Q on the divided surface of the divided locking portion 1, the insertion of the cable Q from the divided portion between the locking portion 1 and the crimping piece 2 is facilitated.

Further, the support member 3 can detachably connect another cable support 4 to a lower portion of the support member 3. That is, the support member 3 shown in FIG. 6 has a band insertion hole 3A opened at the lower end of the loop-shaped support member 3, and a cable support 4 for binding such as a nylon band or a vinyl tie is formed in the band insertion hole 3A. Is to be inserted. In FIG. 7, a pair of hook-shaped cable supports 4 are formed so as to face each other by extending the lower end of the support member 3, and the cable Q is connected to the cable support 4 from the opened lower end of the cable support 4. Is to push. 8 and 9 show that the cable support 4 is connected to the lower part of the support member 3 continuously. This type of cable support 4 has a pair of connecting tools 4 above and below the cable support 4.
A and 4B are provided, and a connecting member 3B provided at the lower end of the supporting member 3 and these connecting members 4A and 4B are connected so that a plurality of cable supports 4 can be connected.

[0016]

According to the present invention, the above-mentioned configuration achieves the original object.

That is, according to the first aspect, the cable Q is formed by utilizing the groove P1 formed on the lower surface of the deck plate P.
Wiring work can be performed extremely reasonably. Moreover, the synergistic action of the locking portion 1 and the crimping piece 2 enhances the fixing force and stability when the support of the present invention is mounted in the groove P1, and can reliably support the cable Q.

Furthermore, since the support of the present invention can be mounted from the side of the cable Q, the work efficiency of the cable wiring work can be greatly improved.

The second aspect of the present invention is extremely versatile because it is easy to add cables to be wired according to the situation at the construction site.

As described above, according to the present invention, various useful effects such as efficient cable routing can be achieved by utilizing the grooves on the lower surface of the deck plate.
