BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure for a system ceiling, and particularly to the ease of assembling the frame itself,
The present invention relates to a skeleton structure of a system ceiling that can secure and standardize dimensions of installation areas of equipment and ceiling panels.

[0002]

2. Description of the Related Art As a conventional system ceiling, lighting equipment such as a fluorescent lamp and other equipment such as an air conditioner, a sprinkler, a speaker or a smoke detector are arranged in series to form an equipment line. There is known a ceiling structure in which ceiling panels are arranged on both sides of the vehicle (Japanese Patent Laid-Open No. 62-2564)
(See Japanese Patent Publication No. 5). In this system ceiling, a finishing material for mounting equipment is supported at appropriate intervals on a base material suspended by a suspending member suspended from a ceiling slab, and lighting equipment and air conditioning equipment are provided between a pair of finishing materials. This is a structure in which equipments such as are arranged in a straight line and a ceiling panel is installed between adjacent finishing materials. Therefore, in this type of system ceiling, since the installation space for the entire equipment is secured, it is possible to assemble the equipment relatively easily. Further, since the equipment line is separated from the ceiling panel and arranged linearly, the installation of the ceiling panel is easier than the system ceiling in which the equipment is installed at an arbitrary position on the ceiling surface.

[0003]

However, in the frame structure of the above-mentioned system ceiling, in the field, after suspending the base material, the finish material is supported while measuring the dimensions, and the equipment is mounted between the finish materials. There is a problem that it requires a lot of labor and time to assemble the frame because the openings for the roof and the openings for installing the ceiling panel are formed. Further, since the finishing material is simply fixed to the lower surface of the base material to form the opening for mounting the equipment between the pair of finishing materials and the opening for mounting the ceiling panel between the adjacent finishing materials, respectively. However, the dimensions of the respective installation areas may become unstable, and the installation of various equipment and ceiling panels may be insufficient.

The present invention has been made in view of the above circumstances, and is a system for facilitating the assembling of the skeleton itself and for ensuring and standardizing the dimensions of the installation areas of various equipment and ceiling panels. It is intended to provide a frame structure for a ceiling.

[0005]

In order to achieve the above object, a frame structure for a system ceiling according to the present invention has a base material suspended horizontally and in parallel via a ceiling suspension member, and a lower surface of the base material. A finishing material that is supported orthogonally to each other to form a single line of equipment, a tentering material that is provided between the pair of finishing materials, and a finishing material that is opposed between the equipment lines. And a tentering member attachment portion and a joining member attachment portion are provided at predetermined positions along the longitudinal direction of the finishing material, and the tentering material and the joining member are formed to have predetermined dimensions, respectively. , Providing engaging portions at both ends thereof, and engaging and fixing the engaging portions to the tenter material attaching portion and the joint member attaching portion of the finish material to form a predetermined facility equipment installation area and ceiling panel installation area. It is characterized by what is done.

In the present invention, it is preferable that the finishing materials are connected to each other in the longitudinal direction via a joint and a breath member is stretched between the finishing material and the base material and the hanging member.

[0007]

According to the frame structure of the system ceiling of the present invention constructed as described above, along the longitudinal direction of the finishing material which is orthogonally supported on the lower surface of the base material suspended by the ceiling suspension member. Providing the tentered material mounting portion and the joint member mounting portion at predetermined positions, and providing the engaging portions at both ends of the tentered material and joint member of a predetermined size, and attaching these engaging portions to the finishing material tenter material By engaging and fixing the portion and the joint member attaching portion, the finishing material and the tenter material and the joint member can be easily assembled. In addition, it is possible to secure the dimensions of various equipment installation areas and ceiling panel installation areas to a predetermined dimension, and to standardize the framework of the system ceiling having these installation areas. Furthermore, lighting equipment, other equipment, and ceiling panels can be easily assembled in these areas.

Further, the finishing materials are connected to each other in the longitudinal direction through joints, and the breathing member is stretched between the finishing material and the base material and the hanging member, so that various equipment equipment areas and ceiling panel installation areas can be provided. Since the and can be held in a grid pattern, it is possible to secure sufficient strength for mounting various equipment and ceiling panels.
