Drainage basins structure of expansion joint devices

摘要

(57) [summary] [purpose] to prevent the scattering of rain water that flows down along the water stop plate, also it is possible to prevent rainwater from entering the internal side, to improve the drainage function. [Configuration] two precursors 13a adjacent to each other with a space L, Over between 13b, inside the horizontal cross section the space L 1 In the drainage structure of the expansion joint device with a water stop plate 18 having flexibility to curved convexly toward the 5, and the water stop plates 1 Below the eight, the waste water outlet 48 which opens so as to face the outside 16 Once, a condenser water inlet 45 which is open facing upward, the condenser water inlet 4 It said it faces from internal 15 side to 5 rises above the rising surface 4 The box-shaped water collecting basins 36 9 and is formed is provided, the water stop plate 18 the lower end 18a is at least the rising surface 49 It is provided so as to reach the.
