FORMWORK FOR PRECAST CONCRETE MEMBER INTEGRATING BEAM AND COLUMN-BEAM JOINT SECTION AND PRODUCTION PROCESS OF PRECAST CONCRETE MEMBER INTEGRATING BEAM AND COLUMN-BEAM JOINT SECTION USING THE FORMWORK

摘要

PROBLEM TO BE SOLVED: To provide a formwork for precast concrete member capable of reducing labor hour and cost of separately casting concretes of different strength, improving efficiency of production operation, and integrating the concretes.;SOLUTION: The formwork 20 comprises a beam section formwork 22, a column-beam joint section formwork 24, and a partition member 26. The partition member 26 is inserted to or removed from a cast dividing section of casting spaces 36, 38 for beam concrete. The partition member 26 is equipped with a partition plate 44 and a plurality of sheet members 46. Each sheet member 46 bends in contact with a beam bottom bar T1 at a part where the beam bottom bar T1 is inserted so as to allow the beam bottom bar T1 to be inserted through a beam main bar insertion groove 4402, and every sheet member 46 is made to plug the beam main bar insertion groove 4402 except the ones where the beam bottom bar T1 is inserted. Also, each sheet member 46 is attached so that it may deform or shift in its upward extraction, allowing the beam bottom bar T1 a relative shifting in the beam main bar insertion groove 4402.;COPYRIGHT: (C)2010,JPO&INPIT
