DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a suspended ceiling structure,
The present invention relates to a ceiling frame horizontal member that is used as a ceiling frame structural member and is suitable for arranging building equipment such as lighting fixtures facing the indoor side inside the member.

[0002]

2. Description of the Related Art In recent years, a single-layer ceiling frame has been proposed in place of a conventionally used double-layer ceiling frame composed of a field support and a field edge. A single-layer ceiling frame does not use unnecessary ceiling frame members, which saves materials used, and does not use complex ceiling frame members in the ceiling construction space. When installing piping for building equipment to be installed, it is easy to install without disturbing the ceiling frame members, the number of component parts is small, and in many cases, prefabricated materials are used instead of semi-prefabricated materials. Various advantages can be obtained, such as a reduction in manual work at the site such as an unloading operation and a cutting operation, and ease of construction. In addition to such advantages, proposals have been made to accommodate the building equipment to be exposed indoors in the ceiling frame member itself, thereby simplifying the ceiling structure and facilitating the assembly work. However, as for the members for ceiling frames that house the building equipment to be exposed indoors, the construction results thereof are very small, the technology has not been established, and the completed ceiling has many problems.

[0003] One example of the above-mentioned problems is related to the reinforcement of the horizontal members. The single-story ceiling frame has the advantage of managing parts composed of a small number of members, and in order to rationalize the assembly work, the horizontal members used for it are long and large. The length of the suspension span in which both ends are suspended by a suspension member from the ceiling slab has also been increased in size. In addition, since the single-layer ceiling frame employs a simple frame structure, the stress acting on the ceiling frame is not distributed to other members and the individual unit transverse members themselves bear the burden. Consideration must be given to sufficient stress in the horizontal members themselves. In addition, when building equipment is housed in the horizontal member, further consideration is indispensable for reinforcement of the horizontal member because a stress load due to the load of the building equipment is also added. An example of the next problem relates to the attachment of equipment to the ceiling frame member. When equipment is mounted on a horizontal member that is a ceiling frame member, it is possible to directly install the equipment on the horizontal member. Providing mounting means for equipment on the exposed surface significantly deteriorates the appearance of the ceiling and cannot be adopted at all. Therefore, the mounting means will be provided in a place where the horizontal member is not exposed in the room, but such a place is often a small space,
Not only is it difficult to install the equipment and equipment, but also when the installed equipment and the like are to be repaired later, a sufficient working space cannot be secured, and the repair work becomes difficult. Another example of the problem is an example in which a lighting device is provided in a cross member internal space having a groove-shaped cross section, and in many cases, the lighting device is arranged at intervals in the cross member internal space. , Other equipment will be placed between the lighting equipment,
When the light from the lighting equipment reaches the place where the other equipment and equipment to which the equipment is communicated, light leaks from the horizontal member where the other equipment and equipment are installed, and the lighting becomes incongruous. That is.

[0004]

The problem to be solved by the present invention is to improve the drawbacks of the above-mentioned conventional products, and not only to be used as a member for a ceiling frame, but also to install building equipment and devices that are exposed indoors. The case is easy to install,
It is another object of the present invention to provide a horizontal member for a ceiling frame which can block light from an enclosed lighting device and reinforces a bending load.

[0005]

In order to solve the above-mentioned problems, a transverse member for a ceiling frame of the present invention has a substantially U-shaped cross section, and means for suspending both longitudinal ends from a ceiling slab. And a bottom plate portion along the lower side of the space having a shape adapted to the cross section of the space opened to the lower side of the cross-section of the main body of the substantially inverted U-shape. A partition member having the partition member in the space at a predetermined position in the longitudinal direction of the horizontal member at least in a top wall portion of the horizontal member and a side wall portion continuous with the top wall. The main feature is that the top portion and both side portions of the partition member are fixedly attached to partition the space in the length direction.

[0006]

The partition member is inserted into a space opened downward at a predetermined position in the longitudinal direction of the horizontal member mainly having a substantially U-shaped cross section.
Since the top portion and both side portions of the partition member are fixedly attached to at least the top wall portion and the both side wall portions that are continuous with the top wall of the transverse member, the transverse member mainly having a substantially U-shaped cross section. In the partition member mounting position, the space fixes the top wall and both side walls of the horizontal member mainly by the partition member and does not cause the cross-sectional deformation of the horizontal member, Can sufficiently resist the deformation due to the bending load, and the strength and rigidity of the entire transverse member can be increased. Further, since the partition member attached to the cross member main body has a bottom plate along the lower side of the space in a shape conforming to the cross section of the space opened below the cross section of the cross member main body, When mounting the building equipment to be exposed to the room mainly to the frame material, the bottom plate can be used as a mounting part of the building equipment, so that the mounting part can be mounted well without exposing the mounting part to the outer surface. In addition, the work space around the mounting portion can be widely taken, so that the mounting work is easy, and the working space does not run short even when the mounted building equipment is repaired. Further, since the partition member attached to the cross member main body has a shape adapted to the cross section of the space opened to the lower side of the cross member main section, the partition member is released to the lower side of the cross member main body. In the space, the light beam of the lighting device provided on one side of the partition member is blocked by the partition member, and the light does not reach the other side of the partition member, and is located on the other side of the partition member. It does not cause unnatural light leakage from other building equipment arrangement spaces.
