[0005]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional example, since the condensed water W accumulated in the water storage part 14 is drained by the horizontal (no water gradient) drain groove 15, it cannot be drained smoothly, and a large amount of dew water W accumulates in the water storage part 14. In addition, there is a problem that water runs along a gap between the gutter 13 and the step portion 12 and drops to the indoor side. The lower end on both sides of the glass body 2 is the portion where the temperature is most likely to decrease. However, since the drainage groove 15 is located there, the drainage groove 15 is easily closed by freezing, and the capacity of the water storage portion 14 is small. When the cold day continues, there is a problem that the water reservoir 14 is completely frozen, and the dew condensation water W flowing down the glass surface overflows and is dropped into the room.
[0006]
The present invention has been made in view of the above point, and an object of the present invention is to provide a drainage structure for condensed water of a lighting window, which can suppress the condensation of the condensed water into a room.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the drainage structure of the condensed water of the lighting window according to the present invention mounts the periphery of the glass body 2 on the support frame 1 and mounts the glass body 2 on the support frame 1 via the glass body 2. A glass window body 4 is formed by sandwiching the periphery of the glass body 2 between the holding frame 3 and the holding frame 3, and the glass window body 4 can be freely opened and closed by a rising frame 5 rising on the periphery of the lighting opening on the roof surface. In the mounted daylighting window, a waterproof packing 8 is interposed between the lower surface of the glass body 2 and the upper surface of the support frame 1 so as to cover the entire circumference at a position below the inner circumference of the support frame 1, and has a rectangular shape. On the underwater-side frame member 1a of the support frame 1 located below the water, the position of the water-stop packing 8 is further down-dated than the other portions, and the water-stop packing 8 and the upper surface of the underwater-side frame member 1a. And a glass surface to form a deep water storage section 14 for dew condensation water, and to form both corners of the support frame 1 underwater frame material 1a. It drains 15 for draining water of the water storage portion 14 to the outside at a position deviated to a more central side formed between the glass body 2 and the presser frame 3 and Underwater side frame member 1a, further water lower Of the waterproof packing 8 arranged on the frame material 1a, the water sealing packing 8a located at both ends in the longitudinal direction of the underwater frame material 1a is largely laid down under the water, and the water storage is deep. A portion 14 is formed, and a central water-stop packing portion 8b disposed between both end-side water-stop packing portions 8a is reduced in the amount to be kept below the water to form a shallow water storage portion 14 having a small depth. characterized in that the Underwater-side portion than Gawatomesui packing part 8b formed by the fixed space 18 of the switching mechanism of the lock or the like. The dew condensation water W condensed on the lower surface of the glass body 2 flows down along the glass surface due to a water gradient, and the dew condensation water W is received by the water storage part 14 and drained from the drain groove 15 to the outside. When the dew water W is drained in the drain groove 15, the dew water W drained in the drain groove 15 having a water gradient and accumulated in the water storage portion 14 is smoothly drained. As a result, there is no possibility that the condensed water may drop into the room beyond the water storage unit 14. In addition, since the drainage groove 15 is provided at a position closer to the center side from both ends of the lower portion of the glass body 2 where the temperature tends to decrease, the drainage groove 15 is hardly frozen and closed even in winter. Even if the water is frozen in the drainage groove 15, since the water storage portion 14 is deep and has a large capacity, the period until the dew condensation water W overflows from the water storage portion 14 and starts dropping into the room can be extended. Frozen ice melts due to insolation or rising temperature during the day, but it works particularly effectively when the temperature below the freezing point continues, such as when a cold wave arrives. Further, the glass window body 4 is attached to the rising frame 5 so as to be openable and closable, and ends of the watertight packing 8 arranged on the underwater frame 1a are arranged at both ends in the longitudinal direction of the underwater frame 1a. The water-tight packing portion 8a is deeply formed below the water-stop packing portion 8a to form a deep water storage portion 14, and the central water-stop packing portion 8b disposed between both end-side water-stop packing portions 8a is placed under the water. The water storage part 14 having a shallow depth is formed by reducing the amount reserved on the side, and the part below the center side watertight packing part 8b is a fixed space 18 for an opening and closing mechanism such as a lock. Even when the water storage portion 14 having a large depth is provided in the frame member 1a, the fixing space 18 for the opening / closing mechanism such as a lock can be secured.
[0009]
It is also preferable that a drain groove 15 is formed between the end-side waterproof packing portion 8a and the central waterproof packing portion 8b. Even if there is a deep water storage portion 14 or a shallow water storage portion 14, the water can be drained smoothly in the drain groove 15.
