CONCRETE FLOOR SLAB JOINING METHOD
To provide a concrete floor slab joining method that reduces the occurrence of a gap between a filling concrete and reinforcing bars after the filled concrete has hardened.SOLUTION: In a concrete floor slab joining method in which a concrete floor slab is joined through a filling concrete section 30, a filling concrete 31 of the filling concrete section 30 is poured by a filling concrete placement process while a first concrete slab 10 is in service for vehicle traffic, after reinforcing bars 40A are connected to a first joint reinforcement 12 and a second joint reinforcement 22 by a reinforcing bar joining process. Even when the first concrete slab 10 and the first joint reinforcement 12 are displaced due to vehicle traffic, the second joint reinforcement 22 joined to the first joint reinforcement 12 through the reinforcing bars 40A displaces the second joint reinforcement 22 and the cast in place filling concrete 31 following the displacement of the first concrete slab 10. Thus, the occurrence of gaps between the filling concrete 31 and the reinforcing bars of the first joint reinforcement 12 is reduced after the hardening of the filling concrete 31.SELECTED DRAWING: Figure 1
【課題】間詰コンクリートが硬化した後に間詰コンクリートと鉄筋との間の隙間の発生を低減するコンクリート床版の接合方法を提供する。【解決手段】間詰部３０を介して接合するコンクリート床版の接合方法で、補強鉄筋連結工程により第１継手鉄筋１２と第２継手鉄筋２２とに補強鉄筋４０Ａが連結された後に、第１コンクリート床版１０が車両の通行のために供用されているときに、間詰コンクリート打設工程により間詰部３０の間詰コンクリート３１が打設される。第１コンクリート床版１０及び第１継手鉄筋１２が車両の通行により変位しても、補強鉄筋４０Ａを介して第１継手鉄筋１２に連結された第２継手鉄筋２２により、第２継手鉄筋２２及び打設された間詰コンクリート３１も第１コンクリート床版１０の変位に追随して変位し、間詰コンクリート３１の硬化後に間詰コンクリート３１と第１継手鉄筋１２等の鉄筋との間の隙間の発生が低減される。【選択図】図１
