Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a rain sill bead provided on the outer surface of a horizontal frame member of a curtain wall.

<Prior Art> As shown in a schematic vertical sectional view of FIG. 3, a horizontal frame member 1 attached to a mullion H is attached to a glass plate 2 from above and below.
2 is attached via a structural seal material P or the like. Then, the glass plates 2 and 2 are attached so as to be held between the horizontal frame member 13 and the ridge member. The ridge member 3 is composed of a long face plate 31 and a flange 32 which is orthogonal to the face plate 31 and is provided in the longitudinal direction. Flange 32 is glass groove 11
It is fitted through the engaging side 11b provided on the bottom 11a. Further, the drainage port 4 is opened over the corner portion which is substantially the same as the bottom portion 11a and which is formed by the face plate 31 and the flange 32. Therefore, rainwater, dew condensation water, etc. that have entered the glass groove 11 from the glass plate 2 will not reach the bottom 11a.
Is discharged to the outside through the drainage port 4. In order to efficiently discharge the rainwater and the condensed water inside the glass groove 11, the drainage port 4 has a large opening area so that the inside of the glass groove 11 is made to have the same pressure as the outside.

<Problems to be Solved by the Invention> However, if the opening area of the drainage port 4 is increased, rainwater or the like easily intrudes into the glass groove 11 from the outside accordingly.
As a result, rainwater will flow into the room. Therefore, as shown in the figure, it is necessary to attach the outer face plate 5 for raining to the outside of the face plate 31. However, attaching the outer surface plate 5 not only impairs the appearance design of the curtain wall, but also causes a rise in construction labor and cost for the attachment.

<Means for Solving the Problems> The present invention has been made to solve the above problems.
In the rain siding edge member having a side surface substantially formed by the upper plate, the outer plate and the inner plate, a flange for attaching to the glass groove bottom portion of the horizontal frame member is extended from the lower end of the inner plate in the direction opposite to the outer plate, This flange and the corner formed by the flange and the inner surface plate are cut out to open a drainage port, and an outside air introduction hole having a larger opening than the drainage port is drilled above the inner surface plate where the drainage port is opened. It was done.

<Function> Since the drainage outlet for discharging rainwater and dew condensation water in the glass groove is provided, and the introduction hole for introducing the outside air is provided in a large opening state from this drainage outlet, the inside of the glass groove is external. The pressure becomes almost the same, and the rainwater and condensed water inside are efficiently discharged to the outside.
Moreover, the outer surface plate only needs to cover the outside air introduction hole, and thus can be made smaller than the conventional one. That is, despite reducing the outer plate,
The inside of the glass groove has the same pressure as the outside air, improving the drainage function.

<Embodiment> Next, the rain end retaining ledge of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a horizontal frame member 1 attached to the mullion H.
Further, the glass plates 2 and 2 are arranged on the outside of the horizontal frame member 1, and further the lower edge portion 21 and the upper edge portion 22 of the glass plates 2 and 2 are pressed through the packing P and the ridge member 6 is attached. FIG. As shown in the partially omitted perspective view of FIG. 2, the ridge member 6 is a long member formed by an upper plate 61, an outer plate 62 extending in a substantially parallel state from both ends of the upper plate 61, and an inner plate 63 in a substantially side surface shape. Is. At the lower end of the inner surface plate 63, a flange 64 having a constant width in the direction opposite to the outer surface plate 62 is also extended along the longitudinal direction. A drainage port 66 formed by cutting out a corner portion 65 formed by the flange 64 and the inner surface plate 63 is formed at an appropriate portion of the flange 64. Furthermore, the inner surface plate above the drainage port 66
An outside air introduction hole 67 is formed in the 63 so as to be wider than the drainage port 66, for example. The ratio of the opening area of the drainage port 66 to the outside air introduction hole 67 is such that the drainage port 66 is formed by notching the flange 64, and the corner portion 65 formed by the inner surface plate 63 and the flange 64 is similarly cut out. If the hole 67 is made wider than the drainage port 66,
Naturally, the opening area of the outside air introduction hole 67 is larger than that of the drainage port 66.

When the flange 64 having the above-mentioned configuration is engaged with the locking side 11b provided on the bottom portion 11a of the glass groove 11, the drainage port 66 thereof communicates with the bottom portion 11a in the same plane, and thus penetrates into the glass groove 11. The rainwater or the like is discharged to the outside through the bottom 11a-the drainage port 66.

On the other hand, from the outside air introduction hole 67, outside air corresponding to the opening area is naturally introduced into the glass groove 11. Therefore, the pressure inside the glass groove 11 is the same as the outside, and the drainage port 66 having a small opening area can sufficiently exert the discharging function.

<Effects of the Invention> As described above, in the rain sill ledger of the present invention, the drainage port is exclusively for drainage and the outside air introduction hole is exclusively for introducing outside air. Therefore, even if the drainage port has a small opening area. ,
Negative pressure does not occur in the glass groove, and if the opening area is small, rainwater from the outside will not be directly blown in. Therefore, it is sufficient that the outer plate is used only for the outside air introduction hole, so that the outer plate can be made small. As a result, the external appearance of the outer surface of the horizontal frame of the curtain wall is improved, and the attachment cost is reduced.
