[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a curtain wall rain closure structure, and is characterized by achieving a strong watertight function while significantly reducing the number of installation steps. That is.

[Purpose of the invention]

That is, the gist of this invention is to provide a mullion attached to the outer surface of a building frame, a waist panel fixed to the mullion, and a window panel placed on the waist panel while engaging with the mullion. The mullion and the window panel, and the mullion and the waist panel are connected by closing the indoor side with an airtight material to form a vertical space, and each vertical space is connected through an outside air inlet formed on the outdoor side. In addition to making the pressure equal to the outside air, a lateral space is formed between at least the waist panel and the window panel, and a part of this lateral space is opened to the outside to make the pressure inside this lateral space equal to the outside air pressure. At the same time, an equal pressure space is formed between the glass of the window panel and a frame surrounding this glass, and the lower frame of this equal pressure space and the horizontal space are connected to each other through a communication hole provided in the lower frame. forming an auxiliary space on the lateral space side of the airtight material that closes the indoor side between the waist panel and the window panel located above the waist panel and the window panel positioned above,
The auxiliary space communicates with the horizontal space through a communication hole, and it is possible to form a curtain wall structure without using blinds or other attachment members, and to perform rain protection based on the principle of equal pressure. It is an object of the present invention to provide a rain closing structure for a curtain wall, which is characterized in that its watertight function can be improved by making the pressure of the glass groove part equal to the outside pressure.

The inside of this horizontal space 14 is formed at the same pressure as the outside air pressure through an opening provided in a part of the tight material 18, that is, an outside air introduction hole 19, and the auxiliary space B is formed in the upper frame 8a.
It is communicated with the horizontal space 14 through a communication hole C formed in the lateral space 14, and is similarly formed at the same pressure as the outside air pressure. Note that this outside air introduction hole 19 also serves as a water drain hole.

Also, the waist panel 2 is attached to the upper part of the window 3 in the same way as described above, but in this case,
Lower frame 8b of waist panel 2 and upper frame 3a of fitted window 3
An airtight material 22 is interposed between the engagement grooves 20 and 21 provided on the frame side of the upper frame 3.
A air-tight horizontal space 24 similar to the horizontal space 14 is formed in close contact with the outdoor side surface of the room a, and this horizontal space 24 is provided with an opening, that is, an outside air-tight hole 25 provided in a part of the tight material 23, for example. Or tight material 2
It communicates with the outside only through the opening formed by removing 3. The horizontal spaces 14 and 24 formed in this manner are respectively communicated with the vertical space 12 to form equal pressure spaces around the four circumferences of each panel 2 and 3.

Note that the fitted window 3 has the upper frame 3a and the lower frame 3.
b and the left and right vertical frames 3c surround the glass 3d, and form an equal pressure space 26 that communicates with each other between each frame 3a, 3b, 3c and the glass 3d, and this equal pressure space 26 is communicated with the outside air via a communication hole 27 provided in the lower frame 3b.

The fitted window 3 of the above structure has edge frames 28, 28 (shown in the fifth figure) which are respectively attached to the mullion 1 in advance.
It is attached to the mullion 1 by screwing the frame side of each vertical frame 3c to the mullion 1, and auxiliary frames 29, 29 are interposed between the outdoor side of each vertical frame 3c and the mullion 1, A vertical space 32 communicating with the vertical space 12 is created by bringing the tongue-shaped tight members 30, 30 fitted into the vertical frame 3c into close contact with the outdoor surfaces of the auxiliary frames 29, 29.
is formed. This vertical space 32 is also communicated with the outside air, for example, through an opening provided in a part of the tight material 30, that is, an outside air introduction port 31.

〔Effect of the invention〕

As described above, the rain cover structure of the present invention is particularly important in the rain cover between the waist panel and the window panel. It is possible to prevent rainwater from adhering to the airtight material 17 and causing water leakage indoors. That is, when rainwater enters the glass groove for some reason through the auxiliary space B and the communication hole C, it is safe to drain it to the outside through the horizontal space 14. Due to the adhesive force, the airtight material 17 passes through the window panel 3.
Even if rainwater tries to migrate to the side, the capillary phenomenon is cut off by the auxiliary space B, and since the auxiliary space B and the lateral space 14 are at equal pressure, there is no communication hole from the auxiliary space B to the lateral space 14. Water can be easily drained through C, and no water leakage occurs.

Furthermore, an outside air introduction hole 19 between both panels 2 and 3
Rainwater with a certain kinetic energy from the horizontal space 1
Even if rainwater enters the airtight material 17, the rainwater will not reach the airtight material 17 because of the auxiliary space B.

It also consists of a mullion 1 attached to the frame A, a waist panel 2 fixed to the mullion 1, and a window panel 3 placed on top of the waist panel 2 while engaging with the mullion 1. In order to significantly reduce the number of installation steps, a horizontal space 14 and an auxiliary space B communicating with the horizontal space 14 are formed between at least the waist panel 2 and the window panel 3, and this horizontal space 14 is A part of the lateral space 14 and the auxiliary space B are communicated with the outside to make the pressure in the horizontal space 14 and the auxiliary space B equal to the outside pressure, so rainwater etc. can be prevented from entering the indoor side due to the equal pressure principle. Furthermore, by forming the equal pressure spaces 26 around the four circumferences of the window panel 3 that communicate with the horizontal space 14, the inside of these equal pressure spaces 26 can be instantly made equal to the outside pressure. Furthermore, in this invention, outside air is introduced separately into the vertical space and the horizontal space, so that the connecting part between the window panel and the waist panel and between the waist panel and the It is possible to prevent water leakage by instantaneously forming the connection part with the vertical line at equal pressure, and its utility value is remarkable.
