Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure which is applied to general buildings, high-rise buildings and the like, and which combines ceiling units capable of rationalizing ceiling work by integrating architectural finishing work and facility work.

[0002]

13 and 14 show an example of conventional ceiling construction, FIG. 13 is a sectional view of the ceiling portion, and FIG. 14 is a diagram showing the entire construction process of the ceiling construction. First, in step S1, the formwork is marked out, the inserts 51 are driven in to place concrete, and then the formwork is separated to construct the slab 52, and then the inserts 51 are cleaned to mark out the slabs. After performing the temporary scaffolding work, the hanging bolt 53 is connected to the insert 51.

Next, in step S2, a black thread is stretched for positioning to support the air-conditioning main duct 54 and the sprinkler main water pipe 55 with suspension bolts 53, and the lighting main wiring 56 is suspended bolts 53. Supported by. Further, after a black thread is stretched and the ceiling base 57 is hung by the hanging bolts 53, the ceiling base 57 is marked to reinforce the opening to reinforce the opening of the ceiling base 57.
This opening is an opening for attaching the air conditioning outlet 58, the lighting fixture 59, and the sprinkler 60. Next, in step S3, the connection duct 61 is attached to the air conditioning main duct 54, the air conditioning outlet 58 is attached by the suspending bolt 53, and the sprinkler 60 is attached to the sprinkler main water pipe 55 via the connection pipe 62. Further, the connection wiring 63 is attached to the lighting main wiring 56, and the lighting fixture 59 is attached by the hanging bolt 53. Next, the ceiling finishing plate 64 is attached, and finally the outlet cover, the sprinkler head,
Complete by attaching the lighting cover.

FIG. 15 shows the construction process for each type of ceiling construction work. The construction workmen and the equipment workmen involved in the air conditioning, water piping and lighting work in accordance with the construction order shown in FIG. On the other hand, the construction work is sequentially performed from the nth floor to the n + 1th floor to the upper floor.

[0005]

However, in the above-mentioned conventional ceiling work, as shown in FIG. 15, since the workman is different for each work, each work, that is, the work for each workman is intermittent in the same work section. Become. In the case of such intermittent construction, if the work of the craftsman does not reach the amount of work for one day, do the construction together with other work zones on the same day, or
Alternatively, the construction work in the previous process in other work zones will be waited until the work amount for one day is reached. Therefore, in the case of simultaneous work, there will be a loss due to the preparation and movement of the work area, and if you wait until the amount of work for one day is reached, the schedule of the post-process will be hindered and the whole work will be delayed, and the whole work will progress. In the worst case, there is a problem that you may go back for work in half a day.

Further, since all the members related to the ceiling, the air conditioner, the sprinkler, and the lighting are supported by the suspending bolts, the number of suspending bolts is increased and a marking process is required for each working process. There is a problem that it becomes complicated, and most of the work is upward work, so that the work efficiency is low and it becomes difficult work.

The present invention solves the above-mentioned problems, and rationalizes the ceiling work by integrating construction finishing work and equipment work and making it possible to streamline work, and at the same time simplifies the work to simple work. It is an object of the present invention to provide a ceiling structure that combines ceiling units that can be lightened.

[0008]

To this end, a ceiling structure in which the ceiling unit of the present invention is combined is a ceiling structure in which the ceiling 9 is divided into a plurality of ceiling units 6 and the ceiling units are combined. Is frame 10
A lighting device 11, an air conditioner 15, 16, 17 and a fire extinguishing device 18, 21, 22 attached to the frame,
