How to build precast formwork and foundation structure

摘要

PROBLEM TO BE SOLVED: To provide a precast form and the like capable of shortening a construction period at the time of construction of a foundation structure such as piping foundation.;SOLUTION: A precast form 10 is a concrete precast form used for construction of a convex foundation structure such as piping foundation. The precast form 10 has a cylindrical upper member 12 and a lower member 11, where a width of a plane of the upper member 12 is narrower than a width of a plane of the lower member 11, and a side wall of both ends in a longitudinal direction of the upper member 12 is arranged above the side wall of both ends in a longitudinal direction of the lower member 11. A reinforcement 13 to be buried in the foundation structure is provided inside of the upper member 12 and the lower member 11.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
