Description

[Detailed Description of the Invention] [Field of Use] The present invention relates to a lighting support metal fitting, and more particularly to a lighting metal support fitting used for wiring work in a manhole. It is intended to support the lighting to ensure reliable lighting during wiring work.

[Prior Art and its Problems] Underground wiring is designed to connect each wiring in a manhole, and the construction of this manhole is as shown in FIGS. , The ends of a large number of pipes (P) (P) through which wiring is inserted are open, and a plurality of support bars (1) (1) are arranged in parallel in the vertical direction on the other opposing wall. .

The support rails (1) (1) support the wires installed between the opposed pipes (P) (P), so that the support rods (2) (as shown in FIGS. 10 to 12) are supported. 2) is installed. There are usually two types of combinations of the support bar (1) and the support rod (2), one for a small manhole and one for a large manhole. The former one is shown in FIGS. 6 and 7. As shown in, a large number of through holes (11) (11) are penetrated through the strip-shaped support bar (1), and this is made into a wall surface (W).
From the above, it is arranged at regular intervals. Other large manholes have a channel bar with a U-shaped cross section as a support bar (1), as shown in Figs. 8 and 9, and as shown in the same figure, many are provided on the top surface. The through holes (11) and (11) are arranged. In the latter case, the through hole (11) is formed in a gourd shape as a whole by extending the notch (13) from the lower end of the circular hole (12) as shown in FIG. There is.

In the small manhole, a rod-shaped body is installed between the through holes (11) and (11) to support the wiring between the pipes (P) and (P). In the latter large manhole, the supporting rod shown in FIG. (2) Locking head
(21) is locked in the through hole (11) and projected from each support bar (1) (1) as shown in FIG. 12, and the wiring between the pipes (P) (P) is supported by this. .

To connect the wiring in the manhole with the above configuration, it is necessary to sufficiently illuminate the inside of the manhole, but since it is difficult to illuminate the entire area of the manhole brightly, use a normal floodlight or dry cell type handlight. I used it to attach the wire connections and the support rods (2) (2).

For example, by placing the floodlight on the floor surface (D) of the manhole sideways, or by wrapping a cord connected to the floodlight around the support bar (1) (1), etc., the main illumination is performed, and regarding the wiring connection part, This is a method that uses a hand light partially. In some cases, a method of mounting a large number of light projectors in a manhole and illuminating the whole area is also adopted.

In the former method, there is a problem that the workability is poor because the handlight is used especially for the work that requires lighting, and in the latter case, the manhole is heated by the lighting to a high temperature and the working environment Becomes worse.

The present invention has been made in view of the above point, and describes "wiring to be inserted through the manhole by the support rods (2) and (2) attached to the support bars (1) and (1) installed on the wall of the manhole. In the `` illumination in the manhole configured to support '', the task is to improve workability and not to deteriorate the working environment in the manhole. It is a technical issue to be able to fix it at any position.

[Technical Means] The technical means of the present invention taken in order to solve the above technical problem is "a pair of plate-like parts (31) (32) and a connecting piece (33) connecting one side edge of the plate-like parts (31) (32)". And a lighting mounting portion (4) on a mounting plate (3) having a U-shaped cross section, which is configured to surround the front and back sides of the strip-shaped supporting bar (1) and one side edge thereof by the above respective parts. Then, the shaft hole (34) is formed in one of the plate-like parts (31), and the shaft body (30) having the tip end protruding from the shaft hole and biased in the protruding direction is provided in the plate-like part (31). This plate-shaped part
The diameter of the tip of (31) is set to the diameter to fit into the through hole (11) of the strip-shaped support bar (1), and the locking head (2
