<P>PROBLEM TO BE SOLVED: To provide a bridge capable of solving the problem that molten water is permeated to the inside of floor slabs and frozen by discharging snow instead of melting snow on the bridge without requiring running cost and without complicating the structure of the bridge itself for removing piled snow on the bridge. <P>SOLUTION: A bridge 10 consists of at least floor slabs 1, and opening floor slabs 3 are connected to parts of the bridge 10 via elastic bodies 4 (springs, laminated rubbers, etc.), respectively. When vibration of the bridge 10 (vibration Z1 of the floor slabs 1, vibration Z2 of main girders 2) propagate to the elastic bodies 4, a unit 7 that includes the elastic body 4 and the opening floor slab 3 resonates to discharge the piled snow on the opening floor slab 3 downward via an opening 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
