Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technique for mounting lighting equipment and equipment plates on a ceiling.

[Background Art] Conventionally, as shown in FIG. 8, a lighting fixture 2' is spanned between parallel ceiling bars 1, and equipment is placed between the end of the lighting fixture 2' and the ceiling bar 1. A space S' was provided, and a plate 4' equipped with equipment such as an inspection plate, a plate with a speaker, a plate with a sensor, a plate with an emergency light, etc. was arranged in this equipment space S'. However, in the case shown in FIG. 8, the equipment spaces S' are separated and independent, and the sprinkler 5c is installed at the intersection of the ceiling bars 1, so the equipment placed in each equipment space S' When installing and inspecting the sprinklers, it is necessary to install the sprinklers one by one or remove the plate 4' one by one for inspection, and the sprinkler 5c must also be inspected separately. There was a problem. Furthermore, in the past, the four lighting fixtures 2' were installed in different mounting states and lined up in a straight line with respect to the adjacent ceiling bars 1 arranged orthogonally to each other. When the arranged part is considered as a unit of one room (module), 1
The vertical and horizontal lighting distribution of the room is different for each room unit, for example, partitions are arranged along the ceiling bar 1 arranged orthogonally to each other, and each room unit is divided by partitions. In some cases, the lighting fixtures 2' are installed in different mounting conditions with respect to the adjacent ceiling bars 1 arranged orthogonally to each other, so that the unit of one room depends on the arrangement position of the partition. The vertical and horizontal lighting distribution of each room is different, which poses a problem in that the layout of desks within the room can be restricted.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to allow lighting equipment and plates to be gathered and arranged at the intersection of ceiling bars, and to facilitate installation and inspection. To provide a ceiling structure in which four lighting fixtures are arranged at the intersection of ceiling bars to form a square lighting unit, and uniform lighting distribution in the vertical and horizontal directions of the room is achieved. It is in.

[Disclosure of the invention] The ceiling structure of the invention is such that lighting fixtures 2 each having a trapezoidal shape in a plan view are arranged at four corners of the intersection of orthogonal ceiling bars 1. Ceiling bar 1 perpendicular to the inclined edge 3 of
The area surrounded by the perpendicular ceiling bar 1 and the trapezoidal lighting fixture 2 is defined as an equipment space S. Triangular plates 4 in plan view are placed in this equipment space S, and each of the plates 4 is It is placed on a ceiling bar 1 and a lighting fixture 2 whose edges are perpendicular to each other, and by adopting such a configuration,
This achieves the above-mentioned purpose of the present invention. In other words, in the present invention, four lighting fixtures 2 and 4 are installed at the intersection of the ceiling bars 1 that intersect perpendicularly as described above.
By collecting two equipment spaces S, wiring and inspection can be easily done in one place, and
Four trapezoidal lighting fixtures 2 are arranged around the intersections of the orthogonal ceiling bars 1, forming a square lighting unit that looks the same both vertically and horizontally in the room. This allows the overall illumination distribution to be uniform.

Hereinafter, the present invention will be explained in detail with reference to examples. A plurality of vertical ceiling bars 1 and a plurality of horizontal ceiling bars 1 are framed and constructed in a grid pattern. Lighting fixtures 2 each having a trapezoidal shape in plan view are arranged at four corner portions of intersections of orthogonal ceiling bars 1. Lighting fixture 2 that is trapezoidal in plan view
The edges on both sides are inclined at 45° to the bottom of the trapezoid. Each lower flange 10 of the ceiling bar 1 perpendicularly intersects the inclined edges 3 of the flanges 8 on both sides of this lighting fixture 2.
It is posted on. In this way, four lighting fixtures 2 are arranged at the four corners of the intersection of the orthogonal ceiling bars 1. The area surrounded by the orthogonal ceiling bar 1 and each trapezoidal lighting fixture 2 is the equipment space S.
A plate 4 having a triangular shape in plan view is disposed in each of the panels, and each edge of the plate 4 is placed on a ceiling bar 1 and a lighting fixture 2 that are perpendicular to each other. In this way, four equipment spaces S each closed by a plate 4 are arranged at the four corners of the intersection of the orthogonal ceiling bars 1. Necessary equipment is placed on the ceiling in the equipment space S arranged at the intersection of the ceiling bars 1 in this way. Specifically, by attaching arbitrary equipment such as an emergency light 5a, a speaker 5b, a sensor, etc. to the plate 4 that closes the equipment space S, and attaching the above plate to the equipment space S, various equipment can be arranged in the equipment space S. It is. Here, it is not necessary to attach equipment to all the plates 4 available in the four equipment spaces S, and it is sufficient to attach the various types of equipment described above to any plate 4. Although not shown of course, all four equipment spaces S
Place all equipment on 4 plates 4
You may use one that is equipped with all the necessary equipment. Furthermore, the plate 4 may be made of not only a metal plate or a synthetic resin plate but also the same material as another ceiling material 9. Further, the plate 4 can be lifted and removed as an inspection lid, so that the area around the intersection of the ceiling bar 1 can be inspected. Further, a sprinkler 5c is attached to the intersection of the ceiling bar 1, and the piping of the sprinkler 5c can be inspected by lifting the plate 4. Thus, the four lighting fixtures 2 placed at the intersections of the orthogonal ceiling bars 1 form a square lighting unit in plan view, and the area where these lighting units are placed forms a unit of one room ( When considering the intersection of the ceiling bars 1 as the center (module), the lighting fixtures 2 are installed in the same way on each of the ceiling bars 1 that are orthogonal to each other, and as a result, the lighting units are arranged. The lighting distribution in the vertical and horizontal directions of each room can be made almost the same, and when the lighting unit is viewed from below in the room, it looks the same in both the vertical and horizontal directions of the room. The lighting distribution throughout the room can be made uniform, for example, if partitions are arranged along the ceiling bar 1 arranged orthogonally to each other and each unit of one room is divided by partitions. In this example, the lighting fixtures 2 are installed in the same way on each of the adjacent ceiling bars 1 arranged orthogonally to each other, so that the same lighting effect can be obtained even when partitioned. It looks the same both vertically and horizontally in the room. An example of wiring is shown in FIG. 6, where the wiring 6 (indicated by a broken line in FIG. 6) passes above the ceiling bar 1 along the ceiling bar 1, and is connected to a hanging bolt that hangs the ceiling bar 1. 7 to fix the wiring 6 thereto. Since wiring can be performed in this manner, the wiring path can be shortened. A flange 8 is provided at the end of the lighting fixture 2, and the inclined edge 3 of the flange 8 of the lighting fixture 2 is placed on the lower flange 10 of the ceiling bar 1, and as shown in FIG. A ceiling material 9 is placed on the flange 8 at the top of the trapezoidal lighting fixture 2, and the end of the equipment plate 4 is placed on the flange 8 at the bottom of the trapezoidal lighting fixture 2. It is. It goes without saying that the shape of the ceiling bar 1 is not limited to the shape shown in FIG. 7.

[Effects of the invention] As described above, in the present invention, trapezoidal lighting fixtures are placed in each of the four corners of the intersection of orthogonal ceiling bars, and both sides of the trapezoidal lighting fixtures are arranged. Since the slanted edges of the trapezoidal lamps are mounted on the orthogonal ceiling bars, four trapezoidal lighting fixtures are arranged around the intersections of the orthogonal ceiling bars, forming a square lighting unit. If we consider the area in which this lighting unit is placed as a unit of one room (module) and consider the intersection of the ceiling bars as the center, the same effect will be applied to each orthogonally adjacent ceiling bar. As a result, the vertical and horizontal illumination distribution of each room in which the lighting unit is installed can be made almost the same, and when the lighting unit is viewed from the bottom of the room. Now the room looks the same both vertically and horizontally, and the lighting distribution throughout the room becomes even.As a result, for example,
There are no lighting restrictions on the desk layout in the room, and as mentioned above, lighting fixtures are placed at each of the four corners of the intersection of orthogonal ceiling bars, and the ceiling bars and trapezoidal shapes are orthogonal to each other. The area surrounded by the lighting equipment is the equipment space, and triangular plates are placed in this equipment space when viewed from above, and each edge of the plate is placed on the ceiling bar and the lighting equipment that are orthogonal to each other. So,
Not only can equipment be placed using the four equipment spaces shielded by four plates, but equipment and lighting fixtures can be gathered in one place, making wiring and other installations easier, as well as maintenance and inspection. It can be done. Furthermore, by gathering lighting equipment and equipment in one place, wiring paths can be shortened.
