PRECAST CONCRETE SLAB JOINING PART STRUCTURE ON STEEL GIRDER

摘要

PROBLEM TO BE SOLVED: To provide a precast concrete slab joining part structure on a steel girder, without allowing water to stay on support girders supporting filling concrete, by only generating cracks on the end part side in the width direction of the filling concrete, without generating cracks in the middle of the filling concrete.;SOLUTION: A clearance D between end parts of precast concrete slabs 5 and 5 adjacent on the respective support girders 3, is set smaller than a maximum crack interval. Crack inducing parts 10 and 11 are respectively arranged in its boundary direction in a boundary between the respective side precast concrete slabs 5 and 5 on both sides of upper-lower surfaces of the filling concrete 6.;COPYRIGHT: (C)2008,JPO&INPIT
