Description

[Detailed description of the invention] This invention consists of lower members such as a lower stile and lower frame that support a panel such as glass through a backing, and a panel and lower member in a sash assembled from aluminum or aluminum alloy sections. This relates to a structure of a highly watertight sash that prevents rainwater from entering the room through the hollow part of the member during strong wind and rain from between the backing inserted between the member and the backing.

To explain the case of the aluminum sash shoji shown schematically in Figures 1 and 2, wind pressure is applied to the outer surface of the shoji in which a panel 5 is sandwiched between the upper stile 1, lower stile 2, and vertical stile 3 via the backing 4 during strong winds and rain. A is the hollow area 60 around the panel inside the stile.
It becomes significantly higher than the atmospheric pressure B (which can be considered to be normally equal to the indoor atmospheric pressure °C).

For this reason, rainwater along with the wind invades the backing 4 and is forced into the hollow part 6 of the stile, and when the hollow part 60 atm B becomes higher than the indoor atmospheric pressure C, the rainwater invades the backing 4 and is blown into the room. .

If the air pressure B inside the stile is always equal to the outside pressure A, rainwater will not intrude into the stile as described above.

In this way, when the air pressure B inside the stile becomes equal to the outside air pressure A, which is higher than the indoor air pressure, the wind will attack the indoor backing and blow into the room, but rainwater will be prevented from blowing into the room.

This phenomenon has been confirmed through experiments.

7 is a block (liner) for supporting the weight of the panel.

When a panel is permanently fitted into a window frame (so-called dead fitting)
The same applies to the case where a member supporting the panel, such as a blank panel or the like, is used.

This idea uses a simple structure to make the air pressure in the hollow part of the lower part of the sash equal to the outside air pressure, thereby creating a highly watertight sash that improves the watertightness of frames, frames, and blinds into which panels are fitted. This is a device designed for this purpose.

That is, in this invention, the depth (expected) of the lower member such as a stile, frame, or blind that supports the panel such as glass is made larger than that of other members, and the hollow part 6 around the panel of the lower member is The opening (cut) leading to the outside is opened to the outside without being blocked by a vertical member such as a vertical stile or vertical frame to which the lower member is connected, so that changes in external pressure are immediately reflected in the lower member. This change in air pressure is introduced into the hollow parts of the vertical member and the upper member to make the air pressure around the backing 4 and panel 5 equal to the outside air, thereby preventing rainwater from entering due to the above-mentioned pressure difference. It is something.

Next, an embodiment of this invention will be described with reference to the drawings.

3 to 5 show an example in which this invention is applied to a sash shoji, and FIG. 3 shows a state in which the lower stile 2 and the vertical stile 3 are connected.

A perspective view of the corner excluding the backing 4 and panel 5, FIG. 4 is a side view of the same corner seen in the direction of the wing arrow X in FIG. 3,
FIG. 5 is a plan view of the same corner seen in the direction of the wing arrow Y in FIG.

The lower stile 2 and the vertical stile 3 are formed by integrally connecting a front wall portion and a rear wall portion at a partition wall portion, and a backing 4 is inserted through longitudinal grooves 8 and 9 on one side of the partition wall portion. Hollow portions 6 and 11 into which the edges of the panel 5 are inserted are formed.

In this implementation row, the depth of the lower stile 2 (expected: a) is made larger than the depth of the stile 2, and when assembling both types 2.3, a part of the hollow part 6 with a large depth comes off from the stile 3. It is designed so that it opens only to the outdoors.

That is, as shown in FIGS. 4 and 5, although the indoor side portion of the cut 2a of the lower stile 2 is closed by the vertical stile 3, the outdoor side portion is exposed to the outside and an opening 10 is formed.

Moreover, the hollow part 6 of the lower stile 2 is formed by the backing 4 of the through groove 8 and the hollow part 11 of the left and right vertical stile 3 by the end where the panel 5 is not present.
I am familiar with this.

Similarly, the hollow part 11 of the vertical stile 3 communicates with the hollow part (not shown) of the upper stile 1.

Therefore, when strong winds and rain blow against the door, the wind pressure passes through the opening 10 and enters the hollow part 6 of the lower stile, and extends to the vertical stile and the hollow part of the upper stile, so that the entire inside of the stile surrounding the panel 5 is equal to the outside air. It becomes pressure.

Therefore, for the above-mentioned reasons, it is possible to prevent rainwater from penetrating the backing 4 and entering into the frame, and therefore it is possible to prevent rainwater from blowing into the room.

Also, the rainwater that was blown into the lower stile 2 through the opening 10.

It is discharged from the opening 10 and the drainage hole 17 drilled on the lower surface of the lower stile.

Figures 6 to T show the implementation of this invention applied to the lower frame, which is the lower member of the window frame. Figure 6 is a vertical side view similar to Figure 4, and Figure 7 is the same as Figure 5. As shown in the figure, the window frame is fixed to the opening in the wall by welding the anchors 13 attached to the appropriate positions to the reinforcing bars 14 of the building, and the gap between the window frame and the opening is filled with mortar. There is.

The depth of the lower frame 12 is made larger than the depth of the vertical bow 15.

Therefore, the indoor side portion of the cut 12a of the lower frame 12 is closed by the vertical ridge 15, but the outdoor side portion is exposed to the outside and an opening 16 is formed.

When strong wind and rain blows against the panel 5 fitted in the window frame, the wind pressure passes through the opening 16 and enters the hollow part 6a of the lower frame 12.
As with the case of the shoji mentioned above, the inside of the frame surrounding the backing 4 and panel 5 is all at the same pressure as the outside air, and rainwater is prevented from blowing into the room.
The same is true.

A structure in which a hollow part surrounding the edge of a stile panel is communicated with outside air is disclosed in Japanese Utility Model Publications No. 50-127932 and No. 50-1402.
Although it is also shown in Publication No. 38, the structure shown in these publications is to vertically divide the lower stile into two parts (inside and outside), sandwich the panel between these two parts via a backing, and make both ends vertical. Since it is connected to the stile, the strength and rigidity of the lower stile are weakened, and it is difficult to compress the backing strongly enough to increase the waterproof effect of the backing. It is integrally formed to increase the strength and rigidity of the member, and its depth is larger than the depth of the vertical member so that the hollow parts 6, 6a surrounding the edges of the panel are open to the outside air, so it can be used through the backing. The panel can be strongly supported, and when wind and rain blows, the outside air pressure can quickly match the air pressure inside the hollow part of the sash member around the panel, preventing rainwater from entering through the backing part due to the difference in air pressure. This simple structure significantly improves watertight performance.

Note that FIGS. 8 and 9 explain the reason why the conventional structure as shown in FIG. 2 cannot allow external air pressure to pass through the hollow portion 11 of the vertical stile 3.

In the conventional shoji, the outer width 1f@W1 of the lower stile 2 is made almost equal to the inner width W2 of the vertical stile 3, so that they fit tightly together, so that the partition wall a of the lower stile is connected to the hollow part 6 and the opening at the bottom. Also, the end face of the partition wall a completely contacts the partition wall C of the vertical stile 3, thereby blocking the top and bottom of the hollow part 11.

Therefore, the external air pressure that has entered under the partition wall a of the lower stile 2 cannot enter the hollow part 11 of the stile due to the opening.
