Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system ceiling. 2. Description of the Related Art In a first conventional example, as shown in FIG. 5, a downlight 50 as an equipment part is directly suspended by a suspension bolt 51 hanging down from a ceiling slab 52, and a load is applied to a ceiling plate 53. There was nothing. A T-bar 54 is a ceiling support bar for supporting the ceiling plate 53. In a second conventional example, as shown in FIG. 6, an equipment plate 55 is mounted on a pair of parallel ceiling support bars 54, and a downlight 50 is provided on the equipment plate 55. 53 'is a ceiling plate. In the third conventional example, as shown in FIG.
The ceiling plate 53 is provided with a reinforcing member 56 to prevent the ceiling plate 53 from sagging. [0004] However, the first conventional example requires the suspension bolts 51, and the second conventional example requires a large equipment plate 55, which makes ceiling installation difficult and makes it difficult to design the ceiling. There is a disadvantage that the properties are impaired. Further, the third conventional example has a disadvantage that the construction is complicated because the reinforcing member 56 is required. Accordingly, it is an object of the present invention to provide a system ceiling which can reduce the size of a facility plate without requiring a suspension bolt or a reinforcing member. The system ceiling according to the first aspect of the present invention comprises a plurality of ceiling support bars arranged in a grid in a ceiling space, a ceiling plate supported by these ceiling support bars, and
An equipment plate for attaching equipment parts mounted on a pair of intersections of the ceiling support bar;
The corner of the ceiling plate corresponding to the intersection of
And the equipment plate has two edges on the ceiling support.
The other edge is bent at a right angle to form a standing piece
Then, attach a vertical piece of flange with L-shaped cross section to this standing piece.
Attach by a step, and attach the ceiling plate to the horizontal piece of the flange.
The invention is characterized in that the cut portion is mounted . According to the system ceiling of the first aspect, since the equipment plate is held at the intersection of the pair of ceiling support bars and the equipment plate is held on the ceiling support bar, the equipment plate can be downsized, so that the design is not impaired. At the same time, the cut of the ceiling plate is reduced, and the construction is reduced. Also, compared to the conventional example, no suspension bolts are required, and the ceiling plate is not reinforced, so the installation is simple and quick, and the side ceiling plate is used when inspecting equipment parts behind the equipment plate. Can be easily inspected simply by lifting up. An embodiment of the present invention will be described with reference to FIGS. 1 to 4. That is, the system ceiling has the ceiling support bar 1 and the equipment plate 2. The ceiling support bar 1 has a pair of intersecting ceiling support bars 1a. The ceiling support bar 1 has a T-bar as an embodiment, and is arranged in a lattice shape in the ceiling space. These ceiling support bars 1
The ceiling plate 3 is supported in this space to form a ceiling. However, the corners of the ceiling plate 3 corresponding to the intersections of the pair of ceiling support bars 1a where the equipment parts are installed intersect form the cut portions 4. [0008] The equipment plate 2 is for mounting equipment parts, and is engaged at the intersection of a pair of ceiling support bars 1a. The equipment plate 2 of the embodiment forms a right triangle,
Two edges 2a forming a right angle are engaged with the ceiling support bar 1a and held by the ceiling support bar 1a. An edge 2b of the oblique side of the equipment plate 2 is bent at a right angle to form a standing piece 6, and the standing piece 6 has a vertical piece 7b of a flange 7 having an L-shaped cross section.
Are attached by connecting means such as welding, and the cut portion 4 of the ceiling plate 3 is mounted on the horizontal piece 7 a of the flange 7. In this case, the flange 7 is attached to the standing piece 6 while slightly lowering so that the lower surface of the ceiling plate 3 and the lower surface of the equipment plate 2 are flush with each other. A mounting hole 8 is formed in the center of the equipment plate 2, and a downlight as the equipment part 5 is mounted in the mounting hole 8. According to this embodiment, since the equipment plate 2 is held at the intersection of the pair of ceiling support bars 1 and the equipment plate 2 is held on the ceiling support bar 1, the equipment plate 2 can be downsized. While not impairing the design,
The cut portion 4 of the ceiling plate 3 is reduced, and the construction is reduced. Also, compared to the conventional example, no hanging bolts are required, and since the ceiling plate 3 is not reinforced, the construction is simple and quick, and the side ceiling plate 3 is lifted when inspecting the equipment parts 5. Can be easily checked. Although the equipment plate 2 according to the embodiment has a triangular shape, it may have a quadrangular shape. According to the system ceiling of the present invention, the equipment plate is held at the intersection of the pair of ceiling support bars and the equipment plate is held on the ceiling support bar, so that the equipment plate can be downsized. , Not to impair the design,
The cut of the ceiling panel is reduced, and the construction is reduced. Also, compared to the conventional example, no hanging bolts are required, and there is no need to reinforce the ceiling panel, making installation simple and quick. Also, when inspecting equipment parts, simply lift the side ceiling panel Can be checked.
