Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an illumination light mounting structure in a hold of a car carrier.

[0002]

[Prior art]

 In a car carrier, the inside of the hold, which is divided by an outer plate, is usually divided into layers (decks), and about 1600 fluorescent lamps are installed on the deck to secure the illuminance of the deck. Although fluorescent lamps are installed on the deck, special attention must be paid to the breaking of the fluorescent lamp bulb and falling of the lamps because the vehicle runs on the deck.

Conventionally, such a fluorescent lamp fixture is mounted on a deck by attaching a bolt 13 to an abutment plate 12 directly below a bone 11 which is a structural member as shown in FIG. There has been a method of mounting the lighting fixture 6 using the lighting apparatus. As another method, there is a method of suspending a fluorescent lamp using a wire.

[0004] However, the upward work as described above imposes a heavy burden on the worker, and the former method is inexpensive, but has many broken balls and the latter method seems to be easy to install. There was a problem that the wire could not come off from the hook during normal rotation, so it could not be mounted in advance.

[0005] In recent years, so-called leading outfitting has been considered, in which ceiling equipment, which had been mounted upward, is mounted downward. This method of leading outfitting is a method in which the equipment to be mounted on the ceiling is mounted downward, which allows efficient work in a good working environment and the electrical equipment installed throughout the ship in the form of a ship. Since the electrical equipment is installed in the state of a small structure before it has the advantage, it has the advantage that the labor for equipment delivery can be saved.

[0006]

[Problems to be solved by the invention]

 The present invention addresses the above-mentioned situation, and in particular, finds a method that can be equipped in advance in place of the conventional upward working method, thereby reducing the burden on workers, efficiently and easily in a good working environment. The purpose is to install the interior lighting.

[0007]

[Means for Solving the Problems]

 That is, the feature of the illumination light mounting structure of the present invention that meets the above-mentioned object is that one end of the bolt is fixed to the structural member attached to the lower part of the deck by welding at a required length, and the other end is required to be longer than the structural member. Then, a washer is mounted on the base of the protruding portion, and a washer and a nut are mounted on the distal end side of the protruding portion, respectively.In addition, the hanging ring of the lighting fixture having the hanging ring attached between both washers of the bolt protruding portion is inserted. Then, the lighting fixture is suspended and held between the washers by tightening a nut.

[0008]

[Embodiment of the invention]

 Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an example of a mounting structure of the in-hold lighting according to the present invention. As shown in detail in FIG. 2, a bolt 2 is attached to a structural member 1 made of I-shaped steel, L-shaped steel, etc. In the case of a bolt having a required length a at one end, for example, a bolt having a length of 60 mm, a length of about 25 mm is fixed by welding, the other end is projected from the structural member 1, and a washer 4 and a nut 3 are attached to the projected tip. Also, a washer is fastened to the base of the protruding portion of the bolt 2, and an illuminating device 6 having a suspension ring 5 mounted on the upper portion is clamped between both washers of the protruding portion of the bolt 2, and is suspended and held. I have.

As shown in FIG. 3, the lighting fixture 6 includes a fluorescent lighting fixture 6 a having a built-in fluorescent lamp 6 b and an upper suspension ring 5, and the suspension ring 5 is removable. In the figure, reference numeral 7 denotes a mounting portion of the suspension ring 5, and as shown in FIG.

The lighting fixture 6 is installed in the above-structured hold by turning the deck structure upside down and mounting the bolts 2 on the structural member 1 below the deck D in a downward direction. The lighting device 6 is attached through the bolt 2 before the sword rotates forward. Next, wiring is performed to the lighting fixture 6 by using the branch electric circuit 8 to complete the wiring work. At this time, since the work is performed on the structure before it becomes a ship, there is an advantage that the movement of tools is small and the labor of equipment distribution can be saved.

After the installation and wiring of the lighting equipment are completed, the lighting equipment is turned forward and the deck structure is mounted thereon, and is sequentially formed into a ship shape. As a result, it is stable during forward rotation, and the deck structure can be rotated forward without worrying about falling.

Thus, when the outfitting is performed as described above, the fluorescent lamp is turned on when the power is supplied after the deck is mounted, and the lighting in the hold is secured. In the past, since the car deck was fixed inside the ship in a short period of time, it was necessary to secure lighting for work inside the ship, and an installation light was separately arranged on the ship. According to the lighting, after the deck is mounted, the fluorescent lamp can be turned on as long as the power can be supplied, so that it can be used as an erection lighting. Therefore, there is no need to remove the construction light after the construction is completed.

[0014]

[Effect of the invention]

 According to the present invention, one end of the bolt is welded to a structural member having a required length, and the other end of the bolt is projected from the structural member by a required length. And, a washer and a nut are respectively inserted and provided on the tip side of the protruding portion, and the hanging ring of the lighting fixture having the hanging ring attached to the bolt protruding portion is inserted, and the nut is fastened to fix the lighting lamp between the washers. The fixtures are suspended and held.Because the bolts are attached to the hull in advance, the suspension rings are attached to the lighting fixtures in advance, and the lighting fixtures can be installed simply by assembling both. Preliminary outfitting is possible, and the lighting fixtures to be mounted on the ceiling can be attached by downward work, and the wiring work for attaching the lighting and lighting fixtures can be completed with the deck turned over. Therefore, the burden on the operator can be greatly reduced, and each of these operations can be performed in the state of a small structure before being formed into a ship. It has a remarkable effect of reducing the time and labor required to deliver equipment and greatly improving work efficiency.

[0015] Furthermore, since the lighting equipment is fixed with bolts and is stable, there is no fear of falling when the vehicle rotates forward, and there is no danger of falling even if the car runs on the deck. In addition, the equipment of the present invention allows the fluorescent lighting equipment to be used as it is as an erection lighting, eliminating the troublesome work of removing the erection light, which has conventionally required a great deal of time.
