Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system ceiling, and more particularly to an improvement of a system ceiling in which facility equipment such as lighting equipment and air conditioning equipment and a ceiling panel are combined.

[0002]

2. Description of the Related Art As a conventional system ceiling of this type, an equipment line is formed by arranging lighting equipment such as a fluorescent lamp and other equipment such as an air conditioner, a sprinkler, a speaker or a smoke detector in series. A ceiling structure in which ceiling panels are arranged on both sides of a facility line is known (Japanese Patent Laid-Open No. 62-62-62).
25645). In this system ceiling, a finishing material for mounting equipment is supported at appropriate intervals on a base material suspended by a suspension bolt suspended from a ceiling slab, and lighting equipment and air conditioning equipment are provided between the finishing materials. This is a structure in which the equipment such as the above is linearly arranged and a ceiling panel installation space is formed. Therefore, in this type of system ceiling, there are advantages that the installation space for the equipment can be secured, and the equipment can be easily assembled. Also, since the equipment line is separated from the ceiling panel and arranged in a straight line, the installation of the ceiling panel becomes easier and the workability can be improved compared to the system ceiling in which the equipment is installed at any position on the ceiling surface. it can.

[0003]

However, in the conventional system ceiling of this type, since the finishing line is supported by the base material to form the equipment line and the ceiling panel installation space, the equipment line and There is a problem that positioning of the ceiling panel installation space is troublesome and a lot of labor is required for construction. Also, in equipment lines, equipment such as lighting equipment, air-conditioning equipment, and speakers are installed between finishing materials supported by a base material, so indexing the positions where these equipments are attached is troublesome. There was also a problem.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a system ceiling in which the mounting areas of the equipment and the ceiling panel are clarified and the equipment and the ceiling panel are easily mounted. It is a thing.

[0005]

In order to achieve the above object, the system ceiling of the present invention is connected in a cross shape between a facility line for continuously mounting facility equipment in the length direction and the facility line. A joining member, and a plurality of ceiling panels installed in a rectangular space formed by the equipment line and the joining member, the equipment line, a finishing material continuous in parallel in the length direction, It is composed of a tentering material which is orthogonally connected at appropriate intervals between the finishing materials, and the finishing material and the tentering material partition and form a lighting equipment mounting area and other equipment equipment mounting area. It is characterized by that.

In the present invention, the finishing material may be suspended by a suspension bolt suspended from the ceiling slab, but it is preferable that the finishing material is supported by the base material suspended from the ceiling. .

[0007]

According to the system ceiling of the present invention configured as described above, the connecting member is connected in a cross shape between the equipment lines for continuously installing the equipment in the length direction to form the rectangular space. The facility equipment installation area and the ceiling panel installation area can be partitioned in a straight line, and the equipment equipment and the ceiling panel can be easily installed. In addition, the equipment line is composed of finishing materials that are continuous in parallel in the length direction, and tentering materials that are connected in an orthogonal shape at appropriate intervals between the finishing materials. By partitioning the lighting equipment installation area and other equipment equipment installation areas with materials, the equipment line can be reinforced, and the installation position of each equipment equipment can be clarified to facilitate the installation of equipment equipment. it can. Further, by supporting the finishing material with the base material suspended from the ceiling, the mounting portion of the equipment can have a robust structure.
