JPS5911197Y2 - Drainage structure of the lower frame - Google Patents

Description

[Detailed explanation of the idea] This invention relates to a 1,000-frame drainage structure.

In the sash frame, in order to prevent rainwater from entering from the glass seal part, an air introduction hole is opened in the lower frame of the sash frame, and by introducing outside air, the pressure inside and outside of the glass is the same. Measures are in place to prevent rainwater from entering.

The air intake hole mentioned above will also be used as a drainage hole, so in the unlikely event that rainwater gets in,
The rainwater that entered the room flowed into the air intake hole, and the air sucked in from outside caused the rainwater to flow backwards and enter the interior of the room.

The purpose of the present invention is to provide a unique water drainage structure that can eliminate the above-mentioned drawbacks of the conventional method.

The structure of the present invention will be explained in detail based on the embodiment shown in the drawings. A glass fitting groove 7 is formed by connecting the lower end of the wall 5 provided with the airtight material mounting portion 4 facing the airtight material mounting portion 2 and the lower end of the groove wall 3 with a bottom plate 6. I am admonishing you.

In the figure, reference numeral 8 indicates a guide plate provided at an angle to facilitate air introduction, and reference numeral 9 indicates a sill plate continuous with the guide plate 8, from which a rail 10 is protruded.

Fitting holes 11 into which an air introducing tool B (to be described later) is fitted are bored in the bottom plate 6 at positions located at both ends of the glass-fitting portion of the glass-fitting groove 7, extending throughout the glass-fitting groove 7. .

Then, on both sides of the fitting hole 11, there are small drain holes 12 whose width is smaller than the width of the glass fitting groove 7 and whose length is shorter.
12' is drilled in the bottom plate 6.

As shown in FIGS. 1 and 3, the air introduction device B has a longitudinal indoor side wall 13, an outdoor side wall 14, and a side wall 15. 16 constitutes a rectangular case, and the side wall 1
5. A connecting wall 17 parallel to the connecting wall 16 connects the connecting wall 16 at the center, and air introduction holes 18 and 1g are formed on both sides of the connecting wall 17.

The height is approximately four times that of the bottom plate 6, the lower end of the indoor side wall 13 is positioned above the lower end of the outdoor side wall 14, and the lower ends of both side walls 15 and 16 are inclined.

And both side walls 15. Mounting pieces 19, -11 to be mounted on the bottom plate 6 are protrudingly provided at both ends of the central portion (in the height direction) of the indoor outer wall 13. 3 that engages with the lower surface of the bottom plate 6 at both ends of 14
Square-shaped protruding pieces 20, 1-1 are provided in a protruding manner.

The embodiment of the present invention is constructed as described above, and when the air introducing tool B is inserted from above into the fitting hole 11 provided in the glass fitting groove 7, the triangular protruding piece 20, The indoor/outside walls 13 and 14 provided with one bend inward and pass through the fitting hole 11, and after passing, return to their original state and engage with the lower surface of the bottom plate 6,
The mounting pieces 19, --- are mounted so that they come into contact with the upper surface of the bottom plate 6 so that the air introduction tool B does not come off.

In this state, the air introduction tool B is in a state of vertically protruding from the bottom plate 6.

After installing the air introduction tool B, fit the glass plate.

Outdoor air is introduced through the air introduction holes 18, 18' of the air introduction device B projecting downward from the bottom plate 6 as shown by arrow C in Fig. 4, thereby equalizing the indoor and outdoor air pressure of the glass plate. This prevents rainwater from entering.

In the unlikely event that rainwater enters, the rainwater will pass through the glass fitting groove 7, and since the air introducing device B protrudes upward, it will flow through the drain holes 12, 12' as shown by arrow D in Fig. 4. like,
leak to the outside.

Note that the water drain holes 12, 12' are the air introduction holes 18. 18'
Because the holes are smaller than those in the drain holes 12, 1
Air introduction holes 18, 18 without being introduced from 2'
Since it will be introduced only from ', there is no risk of rainwater backflowing.

Moreover, since the lower part of the air introduction device B projects below the bottom plate 6, rainwater flowing out from the drain holes 12, 12' is not caught up and caused to flow back through the air introduction holes 18, 18'.

In the above embodiment, the air introduction hole 18. 18' are provided on both sides, but one large air introduction hole 18 may be provided without providing the connecting wall 17.

Since the present invention has the above-mentioned structure and function, the rainwater that has entered will flow out only from the drainage holes 12, 12', and the outside air will be introduced only from the air introduction hole 18, so that the rainwater will backflow and prevent the building from leaking. There is no risk of intrusion inside.

[Brief explanation of the drawing]

The figures show one embodiment of the unique water drainage structure according to the present invention, in which Fig. 1 is a plan view, Fig. 2 is a vertical side view, Fig. 3 is a perspective view of air introduction tool B, and Fig. 4 is a perspective view of air introduction device B. The figure is a longitudinal sectional front view of the main part. In addition, in the figure, A is the frame, B is the air introduction device, 6 is the bottom plate, 7 is the glass introduction groove, 12, 12' are the drain holes, 18, 18
' is an air introduction hole, 19 is a mounting piece, and 20 is a protruding piece.
