  In the sash described in Patent Document 1, a portion that receives a glass window is formed in a cylindrical shape, and the inner side of the cylindrical shape is used as a drainage channel. In order to form such a cylindrical sash, aluminum is used as the material of the sash and molding is performed by extrusion. However, when aluminum is used as the sash material, the fireproof performance of the sash is low. Steel is an example of a material having a high fireproof performance, but it is extremely difficult to form steel into a cylindrical shape by extrusion. For this reason, when using steel with high fireproof performance, there exists a problem that the drainage channel which prevents the movement of the water just under a sash cannot be formed like the sash described in patent document 1. FIG.

  Therefore, the present invention provides a sash structure capable of exhibiting drainage performance as a sash and preventing the movement of water immediately below the sash, and an opening, even if the material is not suitable for forming a cylindrical shape such as steel. An object is to provide a draining structure.

  The sash structure which concerns on one side of this invention is equipped with the holding frame body which hold | maintains a glass window, and the draining support body which supports a holding frame body from the downward direction. The draining support includes a flat portion that receives the holding frame, a first inclined portion that is inclined downward from one side end portion of the flat portion, and a downward inclined shape or a second inclined portion from the other side end portion of the flat portion. And a second inclined portion inclined in a downward inclined direction toward the one inclined portion side. The holding frame is fixed in a state of surface contact or line contact with the surface of the flat portion.

  In this sash structure, water droplets adhering to the first inclined portion side of the glass window and the holding frame reach the flat surface portion of the draining support body due to gravity drop or the like, and are then discharged from the lower end portion of the first inclined portion. The Further, on the side facing the first inclined portion side across the plane portion, there is a second inclined portion that is inclined downward from the flat portion of the draining support or toward the first inclined portion toward the first inclined portion. Is provided. The second inclined portion is flat when the water droplets adhering to the second inclined portion side of the glass window and the holding frame body and the water droplets that have entered the second inclined portion side through the glass window and the holding frame body are flat. In the case of a downwardly inclined shape from the portion, the water is drained from the lower end portion of the second inclined portion, and the movement of the water directly under the draining support is restricted. Further, when the second inclined portion is downwardly inclined toward the first inclined portion side, the water toward the second inclined portion side is blocked by the inclination of the second inclined portion, Waterproofness on the second inclined portion side is ensured.

  Moreover, since the holding frame is attached in a state of surface contact or line contact with the surface of the flat portion, the space between the holding frame and the flat portion is changed from the second inclined portion side to the first inclined portion side. The water can pass from the first inclined portion side to the second inclined portion side. Thereby, when the second inclined portion is downwardly inclined toward the first inclined portion side, the water droplets adhering to the second inclined portion side of the glass window and the holding frame body are removed from the flat portion of the draining support. Then, the second inclined portion moves to the first inclined portion side through the space between the holding frame and the plane portion. In this way, the water droplets adhering to the glass window and the second inclined portion side of the holding frame can be moved to the first inclined portion side and discharged from the lower end portion of the first inclined portion.
