DRAINAGE DEVICE IN DOME-SHAPED STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a drainage device in a dome-shaped structure capable of surely collecting leakage of rainwater infiltrated in the inside of the dome-shaped structure and rationally distributing the drainage quantity so that the rainwater does not overflow in the midway of the watercourse. SOLUTION: The drainage device is provided with a panel retaining member 2 connected to a framing member 1, a panel 3 supported by the panel retaining member 2, and a bead 7 fixing the panel 3 to the panel retaining member 2. The plurality of these panels 3 etc. are arranged adjacent to intersection V where the longitudinal ends of the plurality of panel retaining members 2 etc. mutually access to constitute the dome-shaped roof. In the panel retaining member 2, a waterway is formed to flow the infiltrate water from the roof toward the intersection part V and the water conductiom members 4 etc. directly connect between the downstream side end of the watercourse and the upstream side end of the watercourse of the downstream panel retaining member 2 and the infiltrated water is conducted to flow to the downstream side through the water conduction members 4 etc. COPYRIGHT: (C)2006,JPO&NCIPI
