Description

[Detailed explanation of the invention] [Industrial application field] The present invention relates to a ceiling that takes drainage into consideration.
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 horizontal 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, and the only way to prevent water leaks is to put up a sign to warn passersby under the ceiling that there is a water leak, or to use an appropriate plastic sheet from the leak area. 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 at other locations, it will be necessary to deal with it again, which requires a lot of time and effort, and may also impede traffic in the treated area. cause In addition, various efforts have been made to prevent water leakage in the structure of underground structures, but it is difficult to achieve perfection, and some kind of drainage system in the ceiling structure itself has been desired. In addition, there has been a desire for a ceiling structure that provides a drainage structure on the ceiling of a building that has a roof where there is a risk of water leakage to prevent water from leaking into the room.

Therefore, an object of the present invention is to provide a ceiling that can drain leaking water smoothly and reliably.

[Means for solving problems]

In order to solve the above problems, in the present invention, a large number of ceiling panels whose upper surfaces are waterproof at least are arranged adjacent to each other, and a plurality of ceiling rails are arranged in parallel at intervals, so that one ceiling rail A plurality of panels are commonly supported, a continuous gutter section is formed in the ceiling rail along the longitudinal direction of the ceiling rail to receive water flowing down from the upper surface of the ceiling panel, and a continuous gutter section is formed along the direction perpendicular to the ceiling rail and the ceiling panel A main gutter is provided at the joint position between the two, and a main gutter is provided for reinforcing the ceiling panel that opens laterally at the edge of the ceiling panel in the direction perpendicular to the ceiling rail at the joint position where the main gutter is installed. A groove-shaped frame is provided, and the main gutter is housed in the groove of the adjacent frame of the adjacent ceiling panel, and the water from each of the gutter parts is collected and drained in the main gutter.

[Effect]

In the present invention, a gutter is formed in the ceiling rail that supports the ceiling panel, and leaked water dripping onto the ceiling panel is made to flow down the gutter. Therefore, there is no need to provide a gutter as a separate member, which is preferable in terms of fitting. On the other hand, the water flowing down to each gutter needs to be collected and drained in some way. Therefore, in the present invention, the main gutter is disposed perpendicular to the ceiling rail, and the main gutter is housed in the joint between the ceiling panels. As a result, it is possible to prevent the joints between the ceiling panels from being largely separated from each other and causing an unsightly appearance. In other words, a groove-shaped frame for reinforcing the ceiling panel is provided that opens laterally at the edge of the ceiling panel in the direction orthogonal to the ceiling rail at the joint position where the main gutter is installed, and Since the main gutter is housed in the groove of the frame, the ceiling panel can be reinforced by the presence of the frame, and the frame groove can be used as a housing groove for the main gutter, reducing the appearance when viewed from inside the room. disappears.

[Specific example of idea]

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

FIG. 2 is a schematic diagram of the ceiling according to the present invention, and the structure can be summarized with reference to FIG. 2. Many rows of ceiling rails 1 or 2 are arranged in the left-right direction in the figure. The ceiling rails 1, 1 are arranged at relatively narrow intervals, and equipment lines in which lighting equipment 3 and sprinklers 4 are provided are formed at required locations in the gaps. Further, a ceiling panel 5 is provided straddling the 1 and 2 rows of ceiling rails. ceiling rail 2
At the locations along the rows, only the ceiling panels 5 are supported, and there are no equipment lines for lighting equipment 3 or the like.

With this outline in mind, if we pay attention to FIG. 1A, we can see that the ceiling rail 1 is mounted by means of hanging bolts 6, 6 (only one of which is shown in the figure), which is made of channel steel, and which is fixed to the frame (not shown). It is fixed to the base material 7 with fixing bolts 8. On the other hand, on the ceiling rail 1,
An upward L-shaped lip portion 1b is formed on the ceiling panel 5 side from the middle of the main body piece 1a, and a lining material 1c such as vinyl chloride is coated in the groove formed by the lip portion 1b. , thereby forming a gutter portion 1A. The lower end of the ceiling rail 1 is T-shaped with respect to the main body piece 1a, and one side is the support part 1d of the ceiling panel 5, and the other side is the side of the lighting equipment, such as the fluorescent lamp reflector 9 or the equipment line panel 10. This serves as an edge support portion 1e. 9A
is a fluorescent light.

The ceiling panel 5 has, for example, a honeycomb sandwich panel 5a whose upper and lower surfaces are covered with thin aluminum waterproof surface plates 5b, and whose four peripheries are reinforced with a lip groove-shaped frame 5c, on which a worker stands. It is said to have the strength to not deform. Since at least the upper surface of the ceiling panel 5 is kept waterproof by the aluminum surface plate 5b, leakage water that drips onto the top surface does not pass through the ceiling panel 5 and is kept at a slight installation slope of the ceiling panel 5. Accordingly, it is guided to the gutter section 1A of the ceiling rail 1.

On the other hand, the gutter section 1A described above extends into the frame 5c, and therefore the upper lip 5 of the frame 5c.
d is in a state of hanging down on the groove of the gutter portion 1A. As a result, as shown in the figure, the leaking water that drips onto the ceiling panel 5 and is guided to its periphery flows down into the gutter section 1A from the upper lip 5d.

On the other hand, the lighting equipment 3 dislikes water leakage. Therefore, the mounting plate 11 of the lighting equipment 3 is attached to the mounting piece 1 of the ceiling rail 1.
When fixing to f, a waterproof cover 12 made of metal, for example, is provided above the mounting plate 11 to cover it. Furthermore, a gasket 13 is provided between the waterproof cover 12 and the water pipe to the sprinkler 4 to prevent water from flowing.
The waterproof cover 12 is installed on the ceiling rail 1 by having its end portion engage with the corner portion of the main body piece 1a and the mounting piece 1f. Further, a guide hole 1g is formed in the main body piece 1a from the edge position of the waterproof cover 12 to a position above it. This guiding hole 1g is positioned above the gutter portion 1A.

As a result, water leaking onto the waterproof cover 12 from the equipment line is guided to the periphery along the slope, and drips into the gutter portion 1A through the guide hole 1g. Further, as shown in FIG. 6 (--cross-sectional view of FIG. 1A), the waterproof cover 12 is connected in a waterproof manner.

In this way, the water that has fallen onto each of the ceiling panels 5, 5, . . . and the waterproof cover 12 flows down to the gutter portion 1A of each ceiling rail 1 in the corresponding row.

The water flowing down into these gutter sections 1A, 1A, . . . is collected in the following manner and finally drained through the downpipe.

Next, paying attention to Fig. 1B, we can see that the joints of the adjacent ceiling panels 5, 5 fit together, and the ceiling rails 1, 2
The arrangement of the main gutter perpendicular to the main gutter is shown. That is, the upper lips 5d, 5d of the ceiling panels 5, 5
For example, packing mounting materials 14A and 14B made of PVC are formed with slightly different shapes, and packing mounting materials 15 and 15 are formed between these and the upper surfaces of the ceiling panels 5 and 5.
is provided to prevent water from leaking downward from between the ceiling panels 5, 5. Further, a main gutter holder 16 made of an aluminum profile is fixed to the lower lip portion of one (left and right in the illustrated example) ceiling panel 5, and an upwardly U-shaped main gutter 17 made of, for example, PVC is fixed to the lower lip portion of the ceiling panel 5.
is installed. The length of the main gutter 17 is limited, so it is installed continuously, but the connected part is connected to the connecting material 18.
They are connected to prevent water leakage. Although FIG. 1B is a diagram of the location where the main gutter 17 is provided, the other joints have a similar joint structure except that there is no main gutter.

As shown in FIG. 2, the main gutter 17 is perpendicular to the ceiling rails 1 and 2, and extends to the end of the ceiling across the equipment line where the lighting equipment 3 is not installed. and,
As described above, this main gutter 17 collects water flowing down to each gutter portion 1A. For this purpose, as shown in FIG. 1B, the ceiling rail 1,
1 are arranged in series, and the rising part of the gutter part 1A of the ceiling rails 1, 1 and the lower part of the main body piece 1a are cut out to form cutout parts 1p and 1q. As a result, the water from the gutter parts 1A, 1A flows down from the notches 1p, 1p onto the main gutter 17, and the main gutter 17 can cross the ceiling rails 1, 1 due to the presence of the notches 1q, 1q. It is becoming. Note that it is possible to arrange the main gutter 17 at a position other than the connecting portions of the ceiling rails 1 by providing notches similar to the above-mentioned 1p, 1p, 1q, and 1q in the ceiling rails.

The water thus collected in the main gutter 17 flows along it and is led to the downcomer pipe 19 at the end of the ceiling shown in FIG. As shown in the figure, the end ceiling rail 22 fixed to the ceiling end wall 20 by hole-in anchors 21 has almost the same shape as the ceiling rail 1, and has a gutter section from the end ceiling panel 5. 22A,
and a support portion 22d for the ceiling panel 5. The downcomer pipes 19 penetrate the base side of the support portion 22d and are arranged one above the other. The upper end of this downcomer pipe 19 opens at a lower surface near the end plate 17a of the main gutter 17. As a result, the water in the main gutter 17 is transferred to this downcomer pipe 19.
is drained through. A downhole 22a is formed in the gutter section 22A at the downcomer pipe 19 position, so that water that has fallen into the gutter section 22A drips directly into the downcomer pipe 19 from the downflow hole 22a.

By the way, the ceiling rail 2 outside the equipment line has a shape that is symmetrical to one side of the ceiling rail 1, as shown in FIG. Since its shape and function are clear from the drawings and the previous description, a description thereof will be omitted. 2A and 2A are gutter parts.

In this way, water leaking from above the ceiling flows from the ceiling panel 5 and waterproof cover 12 to the gutter sections 1A and 2.
A, 22A, and further can drain through the main gutter 17 to the downcomer pipe 19. In addition, Figures 2 and 3
The figure shows these drainage routes with arrows.

[Effect of idea]

As described above, according to the present invention, water can be reliably drained through the gutter section of the ceiling rail and the main gutter without leaking water from the underground structure or the roof below the ceiling. Furthermore, since a gutter is formed on the ceiling rail and a main gutter is formed at the joint between the ceiling panels, it is extremely superior in terms of fitting.
