SUPPORT STRUCTURE OF BEAM FORMWORK, SUPPORT METHOD FOR THE BEAM FORMWORK, METHOD FOR PLACING CONCRETE, AND CONSTRUCTION METHOD FOR COLUMN AND BEAM FRAMEWORK

摘要

PROBLEM TO BE SOLVED: To provide a construction method for column and beam framework for installing a beam formwork, in advance, even if the construction of a beam floor on the lower story for construction work is not completed.;SOLUTION: In this construction method for the column and beam framework, PC beam members 72, constituting both of end parts of a beam on the story below the story for targeted construction work, are constructed in advance, when the beam formwork is to be installed at a position for a beam on the story for targeted construction work, and then a beam formwork unit 100, provided with a beam formwork body 20; a lattice frame 51 supporting the beam formwork body 20 from below; and support members 54A, 54B turnably connected with the lattice frame 51 is installed to support the beam formwork body 20 on the PC beam members 72 which constitute both the end parts of the beam, on the story below the story for targeted construction work by the support members 54A, 54B with reactive force taken therein.;COPYRIGHT: (C)2010,JPO&INPIT
