Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower frame structure of an aluminum sash attached to an entrance such as a veranda or an entrance. 2. Description of the Related Art Rainwater sprayed on a sliding door or door by an aluminum sash accumulates in a lower frame of an aluminum sash at an entrance of a veranda or an entrance or the like, and the water flows out to an outside front portion of the veranda or entrance of the entrance or the like. For this purpose, as shown in FIG. 4, a groove 2 is formed in front of a lower frame 1 of an aluminum sash, and water overflowing from the lower frame 1 of the aluminum sash is caused to flow into the groove 2. In general, the drainage pipe 3 buried in a concrete slab is used to flow out to a water collecting hole 4. However, the outside front part of the entrance is made of concrete, and it takes a lot of time and labor to form a groove in the concrete, so that the water can flow smoothly, and a beautiful technology is required to make the appearance beautiful. Is required. Therefore, such a groove accumulates water and is not preferable from the viewpoint of aesthetics. Therefore, the technique disclosed in Japanese Patent Application Laid-Open No. 9-221946 has been developed. In this technology, a drain hole is formed in the lower part of the side wall of the lower frame of the aluminum sash, and this drain hole is connected to a drain pipe buried in the front outside of the entrance and outlet to discharge water accumulated in the lower frame, The drainage structure is buried and cannot be seen from outside. However, according to the above technology, the drain pipe connected to the drain hole of the lower frame of the aluminum sash must be buried in the concrete on the outside front part with a gradient. In addition, there is a problem that the workability is poor and the cost is high, and when dirt and dead leaves flow into the drain pipe and become clogged, the concrete can be broken and the drain pipe must be taken out before the penetration work can be performed. There is a problem with management. In both of the above techniques, since the drainage pipe and the like are embedded in the concrete, the thickness of the concrete becomes extremely large, so that in the veranda or the like, the entire structure must have a structure corresponding to its weight. There's a problem. Accordingly, the present invention provides an aluminum

The drain hole at the rising part outside the lower frame body.
To drain water collected in the ditch by communicating with the drain hole
, The rising portion of the lower frame body as one side wall,
The other side wall which is opposite via the bottom of a predetermined width is formed and drained.
A water ditch, and this drain ditch is integrated with the lower frame body,
Open the drainage hole opened in the rising part to this drainage ditch,
The water in this drainage ditch is further introduced into the drainage ditch outside the outer front part to the guide groove
So that these drains and guide grooves are
It is characterized by being formed so as to be exposed on the front surface . An embodiment of the present invention will be described below with reference to the drawings in the case of a shoji. The details of the door are different, but the basic structure is the same. FIG. 1 is a sectional view of a main part,
FIG. 2 is an overall explanatory view. In the figure, reference numeral 5 denotes a lower frame main body of an aluminum sash. Since the present embodiment is a shoji, there are two rails 6 and 7, each of which has a shoji 8, 9 is attached. A drain hole 11 is formed at a desired location of the groove 10 inside the rail 6 in which the outer sliding door 8 of the lower frame main body 5 is fitted, in this embodiment, both ends are provided. A drain hole 13 is also formed at a desired portion of the portion 12, in this embodiment, at both end portions, and water accumulated in the groove 10 is discharged through the bottom plate 14 in communication with the drain hole 11. is there. A drain hole 16 is also formed at a desired location above the outer rising portion 12 forming the outer groove 15 of the rail 6, in this embodiment, at both end portions.
The water that has accumulated inside is discharged. In the above description, the case of a shoji screen and the case where there are two grooves via a rail have been described, but there is also a case where there is only one groove such as a door, and in that case, one of the grooves is used. Drainage is possible by forming a drain hole at a desired location of the groove or by forming a drain hole at the rising portion without forming the drain hole. Reference numeral 17 denotes a drain groove having both ends closed. The rising portion 12 of the lower frame main body 5 is used as one side wall, and the other side wall 19 is formed through a bottom 18 having a predetermined width. Are integrally formed along the line. Therefore, the drain hole 13 and the drain hole 16 open to the drain groove 17. The other side wall 19 has the same height as the concrete thickness of the outer front portion 20. 21 is a buried edge. If the height of the rising portion 12 and the side wall 19 is set to be substantially the same, the height of the concrete and the rising portion 12 become substantially the same, so that the foot does not obstruct the foot when going in and out. , And a wheelchair can be passed. Further, if the heights of the two rails 6 and 7 are also substantially the same as the heights of the rising portions 12 and the side walls 19, the usability is further improved. Further, the height from the outermost side wall 19 to the rising portion 12, the outer rail 6, and the inner rail 7 may be sequentially adjusted so as to have a smooth gradient toward the outside. Reference numeral 22 denotes a check valve, which allows air to flow from the drain hole 11
This is to prevent water and insects from entering. 23 is a guide groove provided as needed.
For example, when the outer front part 20 is a veranda or the like, the drain groove 17
The water is further guided to the drainage groove 24 outside the outer front face part 20, and the required number of watersheds are provided at both ends of the drainage groove 17 and between them. As shown in FIG. 3, the height of the side wall of this guide groove 23 is also equal to the thickness of the concrete of the outer front surface portion 20, and a buried edge 25 is formed on the outer side of the bottom, and also serves as a locking portion. . According to the lower frame structure configured as described above,
A drain groove 17 integrated with the lower frame main body 5 is formed so as to be exposed on the outer front surface portion 20.
By opening the drain holes 13 and 16 for discharging the water that accumulates at 0 and 15, rainwater sprayed on the sliding doors and doors due to the aluminum sash at the entrance of the veranda or entrance is immediately drained to the drain 17. . Furthermore, the water can be guided and discharged to the drainage groove 24 outside the outer front surface portion 20 by the guide groove 23. Further, since the drain groove 17, the guide groove 23 and the drain groove 24 outside the outer front surface portion 20 are formed to be exposed, the inside of each groove can be cleaned, and if the clogged with dead leaves or debris, it can be cleaned. Can be removed immediately. In addition, the drain 17
Is formed integrally with the lower frame body 5 as an aluminum sash, so that a groove can be formed in which the gradient and the running surface roughness of the bottom and side walls are accurate, and a reliable flow of water can be secured. . According to the present invention described in detail above, the water accumulated in the groove of the lower frame main body is discharged by the drain hole formed in the rising portion outside the lower frame main body of the aluminum sash. By forming the rising portion of the lower frame main body as one side wall and forming the other side wall opposed to the lower frame main body via a bottom portion having a predetermined width to integrally form the drainage groove with the lower frame main body,
The groove will be formed exposed along the lower frame body,
Since its presence does not disturb and can clean the inside of the groove, it has the effect of being able to immediately remove dead clogged with dead or garbage. Further, since the drainage groove is formed integrally with the lower frame body as an aluminum sash, the groove can be formed with an accurate gradient and the roughness of the bottom and side walls, and a reliable flow of water can be achieved. Has the effect that can be ensured.
