Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a draining device for a part that supports a plate-like object such as a windowpane of a sash.

BACKGROUND OF THE INVENTION Usually, window glass is held in a groove-like space of a sash by a watertight material such as a gasket. but,
If this groove-shaped space is not in an equal pressure relationship with the atmosphere, rainwater will easily enter from the joints between the outside gasket, the glass, and the stile due to the difference in air pressure between the inside and outside, and this rainwater will be absorbed by the edges of the window glass. There is a possibility that it may reach the inside of the room through the gasket and enter the room from there.

Purpose of the invention and its solution Herein, the purpose of the invention is to prevent rainwater from entering into the groove-like space in which the plate-like body is fitted, and to prevent rainwater from entering the groove-like space even if rainwater does enter the groove-like space. The purpose is to prevent water from entering watertight parts such as inner gaskets, and to obtain a good drainage function within the groove-like space for fitting plate-like objects such as window glass. Based on the above objective, the present invention brings a water section into contact with the end face of a plate-shaped body, and thereby prevents rainwater that may infiltrate from gaps in watertight materials such as packing materials on the indoor side to prevent rainwater from entering through gaps in watertight materials such as packing materials on the indoor side. The outdoor space and the indoor space divided by the water section are made to communicate with the outdoor atmosphere, so that the isobaric theory can be applied to these spaces as well.

Configuration of main parts of the invention This curtain wall 1 is designed based on the isobaric theory. This isobaric theory is based on the idea that a space is formed inside the outer surface of the curtain wall 1, and the inflow of rainwater is prevented by communicating this space with the outside so that the air pressure in this space is always equal to the outside air pressure. This is the design principle for preventing water leakage by controlling water leakage and achieving a high degree of watertightness. The present invention applies this design principle to the movable shoji 4 and the window glass 5.

First, as shown in FIG. 2, the lower end portion of the window glass 5 is a horizontal space 122 formed by the blind 3, the lower rim 41, and a pair of gaskets 39, 40.
This horizontal space 122 is located inside the lower ridge 41 and the isobaric holes 123, 12 of the blind 3.
4, 125 and the isobaric hole 126 of the retaining plate 56 of the outer cover 54 in a downward direction to the atmosphere outside the room.

On the other hand, the left and right vertical sides of the window glass 5 are attached to a vertical space 122V formed on one side of the mullion 2 for fitting a plate-like body, as shown in FIG. 2 and mullion 2 outdoor wing piece 2a
It is formed between the vertical ridge 47 and communicates with the horizontal space 122.

The vertical space 122V is divided into indoor and outdoor areas by a water section 127 that contacts the end surface of the window glass 5, and in either divided state, the vertical space 122V,
122Vb is also communicated with the horizontal space 122 below to introduce outside air, and is further communicated with each other by equal pressure holes 128 provided at predetermined intervals in the water section 127. This makes it possible to smoothly introduce the atmosphere into both spaces 122Va and 122Vb, thereby ensuring an equal pressure relationship between the vertical spaces 122Va and 122Vb and the atmospheric pressure.

The water section 127 is fitted into a support member 129 fixed to the side surface of the mullion 2 by suitable means such as welding. In addition, the contact part of the water section 127 is
As an example, it is made hollow so that it can be greatly deformed.

Next, in the movable shoji 4, the upper stile 60, the lower stile 61, and the left and right vertical stile 59 are each provided with a horizontal space 130 for fitting a plate-like object, and A vertical space of 130V is provided and they are in communication with each other. especially,
As shown in FIG. 4, the vertical space 130V of the vertical stile 59 is formed between the vertical ridge 86, which has an approximately L-shaped cross section, and the hollow reinforcing portion 83.
is divided into indoor and outdoor areas by a water segment 144 attached to the water segment attachment portion of the vertical rim 86 and having its tip abutted against the end surface of the window glass 89.
Of the vertical space 130V divided into two, the vertical space 130Va on the indoor side is connected to the vertical space 142 inside the rectangular cylinder part through an isobaric hole 139 provided in the boundary wall between the vertical stile 59 and the rectangular cylinder part. In addition, the vertical space 130Vb on the outside of the room is connected to the inside of the rectangular cylinder part through an isobaric hole 138 provided in the water section attachment part and an isobaric hole 140 provided in the boundary wall with the rectangular cylinder part. It communicates with the vertical space 142 of. This vertical space 142 is
Horizontal space 147 in the square tube part of the upper stile 60 and lower stile 61,
Furthermore, this vertical space 142 is in communication with the vertical space 143 which is sandwiched between the outer tight material 97 and the inner tight material 98 between the vertical stile 59 and the vertical frame 104. and the above outer tight material 9
7. The inner tight members 98 communicate with each other through equal pressure holes 141 provided in the vertical frame 59. The above-mentioned vertical space 143 is also formed between the upper stile 60 and the blind 3, between the outer tight material 97 and the inner tight material 98, and into the upper horizontal space, and between the lower stile 61 and the lower frame 64. It communicates with the lower horizontal space 136 formed between the outer tight material 97 and the inner tight material 98,
As seen in FIG. 3, this lower horizontal space 136 includes an equal pressure space 137 formed between the lower frame 64 and the blind 3 holding it, and an equal pressure space 137 formed in the lower frame 64. It communicates with the air pressure hole 150. This equal-pressure space 137 includes an equal-pressure hole 133 provided in the outdoor side rising piece 28 of the open space 3, a gap formed between this rising piece 28 and an outer cover 54 provided on the outdoor side thereof, and It communicates with the atmosphere through a cutout 134 provided in the retaining plate 56 of the outer cover 54.

Therefore, the lower horizontal space 136 and the horizontal space 135 in the rectangular tube part that are in communication with the above-mentioned equal pressure space 137 are both connected to the atmosphere, and at the same time, the vertical space 143 that is in communication with the lower horizontal space 136 is in communication with the atmosphere. , the horizontal space 135 inside the rectangular tube and the vertical space 142 in the rectangular tube that are in communication with each other communicate with the atmosphere, and as a result, the vertical space 130V for fitting the plate-shaped body is divided into two indoor and outdoor vertical spaces. Both 130Va and 130Vb communicate with the atmosphere.

Furthermore, from the above communication relationship, the upper stile 60 and the mume 3
The upper lateral space between the upper stile and the lateral space 147 inside the upper stile corner cylinder part are both in communication with the atmosphere, and the space 130 for fitting the plate-shaped body of the lower stile 61 is connected to the isobaric hole 131 provided in the bottom wall of the space. The horizontal space 135 inside the rectangular tube part through
On the other hand, the space 130 for fitting the plate-like body of the upper stile 60 is connected to the rim 76 and the horizontal space 147 in the square tube part.
Since it communicates with the horizontal space 147 in the rectangular tube part through drain holes 148 and 149 provided in the boundary wall between the inner and outer walls, the horizontal space 130 for fitting the plate-shaped body also communicates with the atmosphere.

action of invention Next, the operation of the present invention will be described.

When the movable shoji 4 is sealed, the outer tight material 97
And the inner tight material 98 is a lower bottom plate 99,
100 and the left and right contact pieces 105, 106, rainwater is unable to enter the indoor side from the outdoor side. However, even if rainwater passes through the gap between the outer tight material 97 and the bottom plate 99, the water is controlled based on the isobaric theory and will not enter the indoor side. In other words, since the atmospheric pressure in the lower horizontal space 136 and the equal pressure space 137 is set equal to that of the atmosphere, rainwater that has entered the lower horizontal space 136 and the equal pressure space 137 does not flow due to the pressure difference, but is affected by the gravity. It flows down based on the isobaric hole 133 and the cutout part 134 as it is guided by the slope 26.
It flows out of the room through . Furthermore, even if rainwater were to infiltrate from the outer packing 91, the rainwater would be controlled by the isobaric lateral spaces 130, 135 and the lower lateral space 136 and flow down to the isobaric space 137, similar to the above. leaks outside the room. In this way, the horizontal spaces 130, 135, the lower horizontal space 136, and the equal pressure space 137 form a sufficiently large volume, so that the equal pressure state can be reliably maintained at that position.
Therefore, the control for preventing rainwater intrusion by isobaric pressure is sufficiently performed.

In addition, the left and right end surfaces of the window glass 5 are water intercepts 127.
Even if rainwater enters through the gap in the outer gasket 39, it will not go around to the indoor side of the window glass 5 and will fall as it is. At this time as well, since the isobaric holes 128 make the vertical spaces 122Va, 122Vb on the indoor side and the outdoor side equal to atmospheric pressure, the rainwater is controlled to flow naturally. This draining phenomenon is caused by the vertical space 130 Va between the window glass 89 and the packing 91 on the outdoor side.
The same goes for 130Vb. However, the water section 144 at this position does not have an isobaric hole 128 in itself like the water section 127. instead of,
The isobaric holes 138, 139, 140 communicate with both the vertical spaces 13Va, 130Vb divided by the water section 144 via the vertical space 142, so that no pressure difference occurs between them. In addition, rainwater that has entered from the upper outer tight material 97 is
Space 147 from the joint surface of vertical stile 59 and upper stile 60
Since there is a possibility that the gas may enter the room, that portion is connected to the outdoor side of the space 130 through exhaust holes 148 and 149 at the ends. Therefore, the rainwater flows into the vertical space 130Vb on the outdoor side partitioned by the water section 144.
and flows down from the isobaric holes 131 and 132. Further, even if there is a strong wind blowing in, the raindrops will not cross the equal pressure space 137 and reach the lower horizontal space 136 upward in the process of passing through the cutout part 134 of the outer cover 54. This is horizontal space 130, 135, lower horizontal space 13
6. This is because the equal pressure space 137 opens only on the outside of the room, and the direction in which raindrops enter is in a direction that opposes gravity.

Modification of the invention In the above embodiment, the window glass is supported by a pair of gaskets, but these gaskets are
It may be a watertight material such as caulking material, and is also used to support plate-shaped objects such as panels in addition to plate glass. In addition, the water sections 127 and 144 of the above embodiment
is held by the mullion 2 or the ridge 86, but it is also possible to hold it by other members at that position, such as the vertical stile 59 or the ridge 47, as illustrated in FIG. For example, it may be constructed integrally with the packing 40 on the indoor side. Of course, the dewatering device of this invention is
The application is not limited to the curtain wall 1.

Effects of the invention According to the invention, even if rainwater infiltrates from a watertight part such as a gasket on the outside, the infiltrated rainwater is blocked by the water cutter that comes into contact with the end surface of a plate-like object such as a window glass, and the rainwater enters the room. Since the contact surface between the inner packing and the plate-like body, that is, the watertight part on the indoor side, cannot be reached, a high watertight function can be expected even between watertight members such as a pair of separated packing.

Moreover, although the water section divides the space formed at the end of a plate-like object such as a window glass into an outdoor side and an indoor side, both spaces after division are open to the atmosphere.
The rain partition function based on isobaric theory can be ensured.
