Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a ceiling structure having a drainage function.
It is used for interior ceilings of underground structures and ceilings of buildings with roofs that are prone to leaks.

[Conventional technology]

Water leakage from above is generally unavoidable in the ceilings of underground structures such as underground malls, underground halls, subway stations, and basements.

Nevertheless, conventionally in this type of ceiling,
There are few measures taken in terms of ceiling structure to prevent water leaks, so either a sign is put up to warn passersby under the ceiling that there is a water leak, or a suitable plastic sheet is used from the leak point. The only thing that could be done was to form a makeshift gutter to drain the water.

[Problems that the idea should solve]

The above method is a temporary and after-the-fact method, and if water leaks occur in other locations, it will be necessary to deal with it again, which requires a great deal of effort and trouble, and may also impede traffic in the treated area. cause In addition, various efforts have been made to prevent water leakage when constructing underground structures, but it is difficult to build a complete structure, and some kind of drainage system in the ceiling structure itself has been desired. There is also a desire for a ceiling structure that provides a drainage structure on the ceiling of a building with a roof that is susceptible to water leakage to prevent water from leaking into the room.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ceiling structure that can smoothly and reliably drain water that falls onto the upper surface of a ceiling panel, and that can fit and stably hold a ceiling panel.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention installs a large number of ceiling panels having continuous upward grooves in parallel, holds each ceiling panel at its longitudinal end on a ceiling rail that extends orthogonally, and A gutter is formed along the longitudinal direction of the ceiling rail, the longitudinal end of each ceiling board faces above the gutter, the longitudinal middle of each ceiling board is suspended from the structure, and the other ceiling board is suspended from the structure. Both sides of the flying ceiling board are secured to the ceiling boards on both sides.

[Effect]

Since grooves are formed in the ceiling plate, water that falls onto the ceiling plate flows along the grooves to the ends in the longitudinal direction of the ceiling plate. On the other hand, each ceiling board is held by a ceiling rail at its longitudinal end, but the ceiling rail has a gutter located below the end of the ceiling board, so water flowing to the end of the ceiling board is From that end it flows down into the gutter, through which it is finally drained, for example, from the end of the ceiling. In this way, the ceiling rail is provided with a holding part for the ceiling board as well as a gutter for receiving water that has fallen onto the ceiling board. Therefore, there is no need to provide a gutter as a separate member, and it is easy to fit.

On the other hand, the ceiling board is installed on the ceiling rail, but if the ceiling board is long, the middle part will be bent and the appearance will be bad. Therefore, in the present invention, the middle part of the ceiling board is suspended to make it planar. Furthermore, although it is not possible to suspend all the ceiling panels, it takes a lot of effort to install, so every other ceiling panel is anchored to the ceiling panels on both sides to simplify the installation. Furthermore, by lifting the non-suspended ceiling plate upward and removing it, it is possible to inspect the interior of the ceiling, which is extremely convenient.

[Specific example of idea]

The present invention will be explained below using specific examples shown in the drawings.

Figure 2 is a ceiling plan, with ceiling rails 1, 1...
are arranged in parallel, and a large number of ceiling plates are arranged between these ceiling rails 1, 1. 2 is lighting equipment, 3
is a sprinkler.

4 is a suspension base made of channel steel, and ceiling rail 1
and is fixed to the underground structure by hanging bolts 5 as shown in FIG. A ceiling rail 1 made of an aluminum profile or the like is fixed to an underground structure via an angle 6 and a hanging bolt 7, as shown in FIG. The ceiling rail 1 has a bottom piece 1 extending outward on both sides from the lower end of the main body piece 1a.
b, 1b, and the supporting piece 1 rising from the end thereof.
c, 1c are formed, thereby the ceiling rail 1
Gutters 1A, 1A are formed along the longitudinal direction. The inner surface of the gutter 1A is covered with a lining material 1d such as vinyl chloride.

The ceiling plates provided orthogonally across the ceiling rails 1, 1 are basically arranged in two types of shapes alternately. That is, especially the first
As shown in the figure and FIG. 4, the first ceiling plate 8A
has a T-shaped hanging portion 8a at the center in the width direction, and also has rising pieces 8c rising up on both sides and having a locking receiving portion 8b at the upper end. The second ceiling plate 8B does not have the above-mentioned hanging portion 8a, and only has a rising piece 8e having outward hook portions 8d on both sides.

The first ceiling board 8A is constructed by hooking the clip 9 to the flange portion of the hanging portion 8a at the longitudinally intermediate portion thereof, and by hanging this onto the hanging base 4.
The middle part is prevented from sagging downward. The second ceiling plate 8B is prevented from drooping by having its both sides locked to the first ceiling plate 8A.

On the other hand, the longitudinal ends of these ceiling plates 8A and 8B face the gutter 1A, and grooves (not shown) are formed by the rising pieces 8c and 8e and the rising parts of the hanging parts 8a. Since the ceiling board 8
The water that fell onto A and 8B flows down from the longitudinal end to gutter 1A, and finally,
As shown in FIG. 2, a downcomer pipe 10 installed at the end of the ceiling
drained from the water.

In addition, in FIG. 3, 11 is a steady rest hook.

The arrangement of the lighting equipment 3 is shown in FIG. 12 is a fluorescent lamp reflector, 13 is a lighting equipment mounting plate, and since lighting equipment hates water, the mounting plate 13 is
A waterproof cover 14 made of an aluminum plate or the like is provided to cover this, and the end thereof is installed on the bottom plate portion of the first ceiling plate 8A. As a result, water that has fallen onto the waterproof cover 14 is guided onto the first ceiling plate 8A, thereby preventing water from leaking into the lighting equipment. The waterproof cover 14 is provided over the entire length of the ceiling board. Further, the sprinkler 3 is provided to pass through 8A, and the penetrating portion is waterproofed with a gasket.

[Effect of idea]

As described above, according to the present invention, water that has fallen onto the ceiling board can be properly drained by being transmitted through the gutter formed on the ceiling rail. In addition, the single ceiling panel is supported in the middle to prevent it from sagging, and the other single ceiling panels are fixed to the ceiling panels on both sides, making the ceiling as a whole extremely stable. Become something.
