JOINT DEVICE FOR SEISMIC ISOLATED EXPANSION JOINT FLOOR

摘要

PROBLEM TO BE SOLVED: To provide an expansion joint floor which eliminates an obstacle to the traffic of pedestrians and vehicles resulting from respective protrusions to be formed from gaps at both sides of a joint plate and rotated protectors for joints after earthquake at an expansion joint between a seismic isolation building and non-seismic isolation building.;SOLUTION: A pair of concave faces are provided on the top face between a building frame and another building frame. Metal base plates 6a are laid on the pair of concave faces, respectively. The metal base plate 6a has an expansion floor sliding part installed with a rising oblique part 7a and a bellows reception part 8a at the rising part of the concave face. An expansion joint floor 10 is installed across the metal baseplate 6a laid on the pair of concave faces. An extensible joint bellows 11a made of a rubber mold and resin a material in contact with the bellows reception part 8a is provided at both ends of the expansion joint floor 10.;COPYRIGHT: (C)2013,JPO&INPIT
