PRECAST MEMBER JUNCTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a junction structure capable of further adequately and easily connecting precast members constituting a concrete structure.SOLUTION: A junction structure comprises: a shear key 1 formed on a joint surface Pa of a precast member P' as one of members to be connected; and a recess 2 formed on a joint surface Pa of a precast member P'' as the other one of the members to be connected, into which the shear key 1 is stored. The shear key 1 is a cylindrical body 1a filled with a fiber-reinforced concrete 6 and comprises one side 1c, which is buried in the precast member P' and the other side 1d of the cylindrical body 1a across a virtual first flat surface x including a central axis 1b of the cylindrical body 1a or a virtual second flat surface y parallel to the virtual first flat surface x. The recess 2 has a shape fitting to an outer shape of the shear key 1 and a depth L1 allowing a part of the shear key 1 to be stored.SELECTED DRAWING: Figure 3
