Description

[Detailed description of the invention] This invention relates to a watertight structure in a curtain wall, which is formed by arranging units constituting the curtain wall in which fitted windows are formed.
It is characterized by being watertight using the principle of equal pressure.

In other words, the gist of this invention is to form a rectangular frame that forms this unit around the four sides of a unit that forms a curtain wall that forms vertical and horizontal spaces that are air- and water-tightly isolated from the outside air and communicated with each other. A unit space that communicates with each other is formed between each of the panels such as the rim and the glass, and the unit space is communicated with the outside air through an outside air inlet and drain hole provided in the lower frame of the frame. The unit space is connected to the vertical and horizontal spaces through a communication port provided in a part of the curtain wall unit, and the four circumferences of each curtain wall unit and the vertical and horizontal spaces adjacent to each other are connected to the outside air pressure. Pressure,
It is possible to improve the watertightness between the inside of the units that make up the curtain wall and the joints between these units, and also to allow outside air to be safely introduced without letting rainwater etc. enter into the joints. The present invention aims to provide a watertight structure in a curtain wall characterized by the following.

Examples of this invention will be described below based on the drawings.

FIG. 1 shows a curtain wall structure composed of units 1 forming the curtain wall. Unit spaces 4 are formed at the four corners of these units, and vertical and horizontal spaces 5 and 6 are formed between adjacent units, which communicate with the unit space 4 through communication ports 19, which will be described later. That is, as shown in FIG. 2, the vertical connection between the units 1 includes a watertight eye plate 8, an airtight packing 9, and a tight material 1 between the vertical frames 1a, 1a of the units 1, 1.
0, a vertical space 5 is created between both vertical frames 1a, 1a.
In addition, the horizontal connecting parts between the units 1 are formed by airtight packing 9 and between the upper frame 1b and lower frame 1c of the units 1, 1 attached to the mullion 7, as shown in FIG. The tight material 11 is interposed to connect the upper frame 1b and the lower frame 1c, and a lateral space 6 is formed between the upper frame 1b and the lower frame 1c.

On the other hand, the unit 1 has a vertical frame 1a and an upper frame 1b.
A panel 13 made of glass or the like is fitted into a rectangular frame 1d having a ridge 12 and a lower frame 1c, and a first unit space 14 is formed between the frame 1d and the ridge 12. At the same time, there is a space 1 of the second unit frame between the rim 12 and the panel 13.
5 is formed. The space 15 of the second unit frame is kept air and watertight by a tight material 16 that uses a molded packing 16' and an irregularly shaped sealing material 16''.These two unit spaces 14 and 15 are As shown in FIG. 4, the units 1 are connected to each other by a raised edge 12 at the lower corner, and outside air inlets and drains 17 are bored at appropriate intervals on the lower surface of the lower frame 1c. Therefore, this outside air inlet/drainage port 17
The pressure inside the two unit spaces 14 and 15 is equal to the outside air pressure via the air pressure. In addition, on the outdoor side of the outside air inlet/drainage port 17, a draining piece 18 is provided vertically downward from the lower frame 1c. Further, the first unit space 14, which is one of the unit spaces 4, is communicated with the double space 5 through a communication port 19 bored in the indoor side of the vertical frame 1a.
Since the horizontal space 6 and the horizontal space 6 are in communication with each other, external pressure is introduced into the horizontal space 6 at the same time. Then,
Vertical and horizontal spaces 5 and 6 between adjacent units
Outside air is introduced into all of the areas. In addition, 21
is a water receiving member provided on the upper part of the unit at the intersection of the vertical space 5 and the horizontal space 6 for each unit. In this case, since an airtight packing is provided around the indoor side of each unit, airtight packings 9, 9 are interposed on the indoor side of each connecting part of the unit.
In addition, tight materials 10 and 11 are interposed on the outdoor side,
Since the internal pressure inside the vertical space 5 and the horizontal space 6 is almost equal to the outside pressure, there is no fear that rainwater or the like will directly intrude. Even if rainwater were to enter the unit space 4 due to some reason, such as capillary action, the unit space 4, that is, the first and second unit spaces 14 and 15, would have an equal pressure with the outside pressure. Therefore, the outside air can be easily discharged from the outside air inlet/drainage port 17. For the same reason, even if rainwater were to enter the horizontal space 6b without a water-receiving member, since the horizontal space 6b is connected to the vertical space 5, the rainwater in the horizontal space 6b would be absorbed vertically. The water passes through the space 5, is received by the water receiving member, flows into the horizontal space 6a, and is discharged outside as will be described later. In this case, as described above, water receiving members 21 are provided at appropriate locations on the bottom surface of the horizontal space 6a, and drain ports 20 are formed in the upper frame of the unit forming the horizontal space provided with the water receiving members 21. A part of the rainwater that has entered the horizontal space 6a can be discharged to the outside from the outside air inlet/drainage port 17 via the gutter 22 provided in the upper frame 1b of the unit 1 and the unit space 4. Note that rainwater that has entered from the vertical space 5 and rainwater that has entered from the horizontal space 6b can be similarly discharged through the gutter 22.

In addition, 23 is a watertight block, and the tight material 1 at the intersection of the vertical and horizontal spaces 5 and 6 is
It is arranged at the part where 0 and 11 are cut.
Note that the portion where the water receiving portion 21 is formed is formed integrally with the water receiving portion 21.

As explained above, the watertight structure of this invention is
A rectangular frame, a selvedge, and facing materials such as glass that constitute this curtain wall unit are placed around the four circumferences of the curtain wall unit, which forms vertical and horizontal spaces that are air-tightly isolated from the outside air and communicated with each other in adjacent areas of the units. A unit space that communicates with each other is formed between the units, and this unit space is communicated with the outside air through an outside air inlet and drainage port that is provided in the lower frame that makes up the frame. Since the unit space is communicated with the vertical space or the horizontal space through the communication port, the space of the unit frame formed around the four circumferences of the curtain wall unit and the adjacent parts of the units forming each curtain wall are connected. It is possible to instantly equalize the pressure of the vertical and horizontal spaces with the outside pressure, and once the four circumferences of the curtain wall unit have been equalized,
Since outside air is introduced into the space adjacent to the units, there is no risk of rainwater or the like entering the space between the adjacent units, and only safe outside air can be introduced. In the case shown in the embodiment, the outside air inlet can be provided not only in the lower frame portion which also serves as a drainage hole, but also in the vertical frame. In this case, the ribbed edge also serves as a butthole, which is convenient because it does not reduce watertightness, and since the fitting groove of the panel of the unit that makes up the curtain wall is made of the ribbed edge, special processing is not required. It has the advantage of allowing the spaces in the unit frames to communicate with each other without any problems, and its utility value is remarkable.
