CAST-IN-PLACE HOLLOW CORE CONCRETE SLAB STRUCTURE, CAST-IN-PLACE HOLLOW CORE CONCRETE SLAB AND ITS CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a more improved cast-in-place hollow core concrete slab capable of facilitating an operation at a site and capable of also enhancing the degree of freedom of the execution of works when the cast-in-place hollow core concrete slab is built.;SOLUTION: An upper-end bar 14 and a lower-end bar 12 are connected by an upper-lower bar connector 40, and the lower-end bar 12 is fixed onto forms 10 by engaging a lower-end member 21 with the upper-end member 25 of a lower-end bar fastener 20 engaged with the forms 10. Consequently, the upper-end bar 14 is not uplifted even when the buoyancy of a buried material 30 works to the upper-end bar 14. Since the lower-end bar fastener 20 is fixed completely to the forms 10 by the operation from the upper section of the forms 10, the operation is easy and safe.;COPYRIGHT: (C)2005,JPO&NCIPI
