PRESTRESS INTRODUCING METHOD TO FILLING PART BETWEEN PRECAST CONCRETE MEMBERS

PROBLEM TO BE SOLVED: To provide a prestress introducing method to a filling part between precast concrete members capable of successively introducing a prestress equal to or more than that of a precast concrete plate to cast-in-place filling concrete in a narrow range. SOLUTION: This prestress introducing method to the filling part between the precast concrete members, introduces the prestress to the filling concrete by return force of the precast concrete plate 13 by opening a load, after its filling concrete reveals required strength, by placing the filling concrete 14 in an expanded filling clearance, by elastically deforming the filling clearance between the mutually adjacent precast concrete plates 13 in the expanding direction, by applying the load for deforming this plate to the precast concrete plate 13.
