Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water leakage protection facility provided under a ceiling for protecting electronic devices and materials such as an electronic computer, an electron microscope, and the like, which are particularly sensitive to water leaking from a ceiling surface.

[0002]

2. Description of the Related Art Conventionally, in a concrete building or the like, rainwater or the like sometimes leaks to lower floors through cracks in a skeleton due to poor construction or aging. In particular, when the lower floor is a computer room or the like in which facilities such as a computer and a precision machine are installed, water leakage may invade these machines and equipment, causing serious damage.

In recent years, in order to deal with such a problem,
Equipment has been proposed in which a waterproof plate is hung from a ceiling to prevent water leakage from dropping onto electronic devices and the like. For example, in Japanese Patent Publication No. 6-96880 (first publicly known example), a waterproof plate is arranged under the ceiling with the edge close to the beam, and a gutter for the beam is provided along the lower edge of the beam. Along with the round gutter wound and arranged below the edge position of the beam gutter,
There is disclosed a water leakage recovery device that collects water flowing down from the waterproof plate to a round gutter via the gutter for beams.

In Japanese Patent Application Laid-Open No. 53-41017 and Japanese Utility Model Application Laid-Open No. 52-28914 (second known example), a waterproof plate is fixedly arranged on a base member attached to a ceiling surface via an anchor bolt. A double ceiling structure is disclosed.

Further, in Japanese Patent Application Laid-Open No. 53-41017 (third known example), an arched ceiling member is arranged on the ceiling side, and a collecting groove member straddling the side edges of adjacent arched ceiling members. Is disclosed.

[0006]

However, in the waterproof equipment according to the first to third known examples, various problems are expected in terms of construction and structure.

First, in the case of the first known example, a waterproof plate must be provided on almost the entire surface of the ceiling except for the beams, and at the same time, the entire waterproof plate must have a structure that does not completely leak water. In practice, it is difficult to cover the entire ceiling surface between beams with a single waterproof plate, so a connection part for the waterproof plate will be provided at a key point, but the watertight structure at this connection part will be complicated In addition, problems such as deterioration of workability occur. In addition, exactly the same problem occurs when a part of the waterproof plate is to be used as an open / close lid for maintenance management, and there is also a problem that it is difficult to repair from the indoor side if water leaks at the connection part. is there. Further, in an ordinary office building or the like, facilities such as a management opening / closing lid, a fire alarm, and an air-conditioning outlet are often provided on a ceiling surface. There are also problems such as inability to deal flexibly.

Next, the second known example discloses a waterproof plate supporting structure that completely blocks water leakage from a connecting portion, but has a complicated structure and poor workability.
It is difficult to deal with the existing ceiling where facilities such as fire alarms and air conditioning vents are installed.Furthermore, there is no disclosure of the treatment of leaked water, and in some cases the leaked water may be behind the waterproof plate. It is also expected to remain stagnant.

The third known example is applied to an extremely narrow room such as a cooking place or a washing place that emits moisture, and is not suitable for an office building having a wide space. Specifically, the same problem as in the first known example occurs.

Therefore, the main object of the present invention is to firstly provide a structure having a simple structure and no fear of water leakage between adjacent waterproof plates, as well as quick installation of the waterproof plates and excellent workability. Secondly, the method of water treatment should be clear and the drainage treatment should be clear, and thirdly, maintenance can be performed easily and ceilings for air-conditioning blowout, fire alarm, lighting, etc. There is a need to be able to easily cope with equipment and to be able to flexibly cope with future changes in the arrangement of equipment.

[0011]

To solve the above-mentioned problems, a ceiling water leakage protection system includes a gutter / frame member having a plurality of frames below a ceiling surface in almost all or a part of a room. In addition to being provided horizontally or slightly inclined, a waterproof plate is detachably attached to an arbitrary frame portion of the gutter / frame member.

More specifically, in almost all or a part of the room, a gutter / frame member formed in a lattice by a U-shaped cross section is provided horizontally or slightly inclined below the ceiling surface. For a given lattice frame of the gutter / frame member, a waterproof plate provided with hanging pieces integrally connected to the periphery from the plate body at the periphery is formed by attaching the hanging pieces to the entire U-shaped section of the grid frame. It is characterized in that it is placed so that the lattice frame of the shaped member covers the side wall.

In this case, the gutter / frame member includes a substantially longitudinally-shaped U-shaped main frame disposed in one side of the lattice frame and the parent frame disposed in the other direction of the lattice frame. A U-shaped cross-section child frame that is laid between frames. A cut-out portion is provided at the sub-frame connection portion of the main frame so that the end of the sub-frame is fitted. It is desirable to adopt a structure fitted and connected to the notch. Still more preferably, at least both bottom plates and engagement flanges extending in substantially orthogonal directions integrally from both side walls are provided at both ends of the U-shaped cross-section frame arranged in the other side direction. It is preferable that the engaging flange is engaged with the formed notch and connected.

On the other hand, in order not to block the illumination installed on the ceiling surface, a transparent resin plate or glass plate is preferably used as the waterproof plate. Furthermore, by using a material having a light-transmitting property, it is possible to easily check a leaking point on the ceiling surface from below without removing the waterproof plate.

Also, the waterproof plates 4, 4,... Can be installed on all or a part of the frame members 1A, 1B. In the illustrated example, on the room L side, the frame member 1A is arranged in almost the entire area of the room except for the vicinity of the entrance, and the waterproof plates 4, 4,... Are installed only in the relatively left area A. On the R side, the frame member 1B is installed in a part of the room, and the waterproof plates 4, 4,... Are installed relatively only in the lower area C. If planning is made in anticipation of a change in the arrangement of equipment in the future, the frame members 1A and 1B are arranged over a relatively large area, and the waterproof plate 4,
It is a more preferable aspect to be able to easily cope with the relocation of 4..

The structure will be described in detail below along with the construction procedure. The ceiling structure of a building is shown in FIG.
As shown in FIG. 2, first, the ridge receivers 12, 12,... Are attached to the suspension bolts 14 suspended from the skeleton slab (not shown).
Are generally supported, and the ceiling plate 13 is supported on the ridges 10, 10, 11... Fixed in place to the ridge receivers 12, 12. In the case of such a ceiling structure, First, the parent frame 2 is suspended from the ridges 10 and 10 as a support.

More specifically, as shown in FIG. 5, blacking is performed on the ceiling plate 13 at the position of the edge 10, and a piece member 9 having a U-shaped cross section is fixed immediately below the ceiling surface of the edge 10. Fixed by. On the other hand, as shown in FIG. 2, a hanging metal fitting 7 having a U-shaped cross-section having a screw coupler 7a fixed at the center thereof is fixed in advance to an appropriate position in the longitudinal direction of the main frame 2 by welding or the like. The lower end of the suspension bolt 5 is screwed into the screw coupler 7a of the suspension fitting 7, and the upper end of the suspension bolt 5 is connected to the lower flange 9a of the piece member 9.
The nuts 6 and 6 are disposed on both sides of the lower flange 9a through the through holes formed in the lower flange 9a, and the upper portions of the suspension bolts 5 are fixed and suspended. In this example, in addition to the support by the hanging bolts 5, as shown in FIGS. 3 and 4, as shown in FIGS. Are stretched between the walls in the horizontal direction on the lower surface side of.

The adjustment of the core of the main frame 2 and the adjustment of the height and gradient thereof can be performed by adjusting the amount of screwing of the suspension bolt 5 into the screw coupler 7a and adjusting the nuts 6, 6. The parent frames 2, 2,... May be arranged horizontally, but are preferably installed so as to have a drainage gradient of about 1/50 to 1/200, and all the parent frames 2, 2,. Will be adjusted to

As the parent frame 2, a single member having no connecting portion is preferably used, but a connecting portion may be provided in the middle due to restrictions on transportation and the like. Of course, in this case, the joint of the connecting portion is sealed to complete the water stoppage. In any case, the parent frame 2
Is installed substantially as a longitudinal thread in the installed state. Further, the support structure of the parent frame 2 may be suspended and supported by, for example, a suspension wire in addition to the support by the suspension bolts 5.

After the parent frames 2, 2,... Are installed under the ceiling according to the above-described procedure, the child frames 3, 3,. The child frame 3
As shown in FIG. 7, a wall height h of which is lower than the wall height H of the parent frame 3 is used.
The rectangular cutouts 2a, 2a, 2a, 2c,
2a, while a bottom plate is provided at the end of the child frame 3,
By forming engaging flanges 3a to 3c integrally extending from both side walls in a substantially orthogonal direction, and dropping the engaging flanges 3a to 3c of the child frame 3 into the notches 2a of the parent frame 2, Both are connected. Thereafter, a seal is applied around the outer surface of the connecting portion to prevent water leakage from the corners k, k of the engaging flanges 3a to 3c and to prevent backlash, thereby completing the connecting operation per one. If the flange shape at the end of the child frame 3 is an engagement flange 3d continuously surrounding the three sides of the bottom surface and both side surfaces as shown in FIG. 8, the child frame 3 is simply dropped. Water leakage from the corner K can be completely prevented, so that a seal is not required and the construction can be simplified.

In this manner, each child frame 3, 3,...
, And as shown in FIG.
A and 1B are constructed under the ceiling. The child frame 3
Is connected to the parent frame 2 so that the waterproof plate 4 described below does not rattle so that the side wall top level of the child frame 3 and the side wall top level of the parent frame 2 are the same.
In other words, in the completed state of the lattice-shaped frame connection 1A, 1B, the upper surface level is made substantially the same.

On the other hand, with respect to an end frame member 16 (hereinafter referred to as a water collecting gutter frame) disposed below the water of the parent frames 2, 2,... In addition, since it must flow down to the water side, as shown in FIG.
In addition, a vertical gutter 17 is provided at an underwater end of the water collection gutter frame 16 so as to reliably discharge water leakage to the outside.

When the installation of the frame members 1A and 1B is completed, the waterproof plates 4, 4... Are then applied to an arbitrary lattice frame, in this example, the area A on the frame member 1A side and the area C on the frame member 1B side. Is installed. The waterproof plate 4 is preferably made of a material such as a transparent resin or glass so as not to block the illumination, and has a hanging piece 4 extending integrally around its periphery (four sides).
a, 4a ... are formed. Using the diagonal portion of the lattice frame, the frame is passed over the frame members 1A, 1B, and as shown in FIG. 9, the hanging pieces 4a, 4a. The lattice members of the frame members 3 are placed so as to cover the side walls. In addition, the waterproof plate 4,
FIG. 6 shows the completed state of the water leakage protection equipment in which 4 are installed.
In this case, it is preferable that the dimensions of the lattice frames are set to be the same as much as possible, and the types of dimensions of the waterproof plates 4, 4,... In this example, as shown in FIG. 1, for the purpose of adjusting the length, the central portion has the same size in a square shape, and rectangular waterproof plates 4 'having different sizes are installed at both ends or one end. ing.

Since the existing ceiling is not originally designed to be able to hang heavy objects, the above-mentioned frame members 1A. 1B
It is preferable to use a member that is as light as possible. Specifically, in addition to a thin C-shaped steel made of stainless steel, a resin material such as a vinyl chloride resin can be suitably used. Also, as for the waterproof plate 4, it is preferable to use a thin waterproof plate as far as possible without causing bending.

With the water leakage protection equipment as in this example, the structure is very simple and the cost is low. In addition, each waterproof plate 4, 4
... Also have small dimensions and are excellent in handling properties, and can be installed simply by placing them, which is extremely excellent in terms of workability. Furthermore, since each of the waterproof plates 4, 4,... Has no connection portion, there is no possibility of water leakage in the future. In addition, if a fire alarm or an air-conditioning outlet is present on the ceiling, if the waterproof plate 4 is left open without attaching the waterproof plate 4 to the lattice frame corresponding to the installation location of these devices, these There is no obstacle to equipment. Maintenance can be performed very easily because the waterproof plate 4 can be inserted into the back side of the frame members 1A and 1B only by lifting the waterproof plate 4 upward from an arbitrary location. Becomes

When water leakage occurs in the water leakage protection equipment, the water leaked from the waterproof plates 4, 4,... Flows down to the child frames 3, 3,. Flow down. And parent frame 2,
The water leaked to 2 ... flows down the water according to the drainage gradient, is collected by the water collection gutter frame 16 at the lowermost end of the water, and is finally discharged to the outside from the vertical gutter 17.

As described above, as one embodiment of the present invention, the parent frames 2, 2,..., The child frames 3, 3,.
A leakage protection system comprising: a parent frame 2;
2 ... then child frames 3, 3 ... and finally waterproof plates 4, 4
The method of performing the construction according to the above procedure has been described in detail. This embodiment is particularly preferably employed when electronic devices are already arranged in a room.In addition, for example, a lattice-shaped frame unit having a predetermined size is manufactured in advance at a factory, and It may be brought to the site and installed. If the lattice frame units can be easily connected to each other, even a large lattice frame can be easily constructed on site. In the case of factory-built frame members,
The members in the X and Y directions of the lattice skeleton are exactly the same,
That is, the parent-child relationship between members in each direction as in this example may be eliminated, and these members may be joined by welding at intersections.

In the case where no electronic equipment is installed and the room is vacant, after laying the ground on the floor, it may be pulled up to the ceiling side with a wire or the like and fixed as it is.

[0031]

As described above in detail, according to the present invention, the structure is very simple because it is basically composed of a frame member and a waterproof plate. In addition, since the waterproof plates do not have a connection portion, there is no problem of water leakage from the waterproof plate connection portion as in the related art. The water plate has a light weight per sheet and is excellent in handleability, and furthermore, since it only needs to be placed in the opening frame portion, the workability is excellent and the work can be completed in a short time.

Further, the method of water treatment is clear and the drainage treatment can be performed reliably, and at the same time, the maintenance can be easily performed. In addition, air conditioning
It is possible to easily deal with ceiling equipment such as a fire alarm and lighting, and it is possible to flexibly deal with future changes in the arrangement of equipment.
