Hinge Connection between Precast Member and Base, Rahmen Structure having such Hinge Connection, and Constructing Method for such Rahmen Structure

摘要

The present invention has a structure in which a concave trench is formed to extend in the transverse direction in the foundation, and the lower end of the precast structure is inserted into the trench to be installed vertically, but the lower end of the precast structure is rotationally displaced in a predetermined angular range inside the trench. By doing so, in a state where the slab is completed on the upper part of the precast structure to form the Ramen structure, rotation is allowed between the lower end of the precast structure and the foundation, so that a hinge connection in a form in which a moment is not transmitted by an external force is made, while precasting is performed. "Precast structure and foundation" that can maintain the stable state of the precast structure by suppressing the displacement of the precast structure as much as possible and preventing overturning without the installation of a separate support member during construction until the slab is built on the top of the structure of a hinge connection structure, a ramen structure having the same, and a construction method thereof.
