PROBLEM TO BE SOLVED: To provide a junction structure for a precast concrete member allowing a high junction strength to be easily obtained and having a junction with a good appearance.SOLUTION: A junction structure for a precast concrete member comprises: female metal fittings 3, 3 each buried in a joint end surface part of each precast concrete member; and a pair of male metal fittings 5, 5 each fitted astride between the female metal fittings 3, 3 of each female connection part 4; and a connection rod 7 for connecting both the male metal fittings 5, 5. Taper-shaped holding groove parts 32, 32 each made wide inside of the connection rod axis direction so as to straddle between the female metal fittings 3, 3 of each female connection part 4 are provided in the male metal fitting 5. Connection parts 21, 21 between the female metal fittings, butted against each other on joint end surfaces thereof and fitted into the taper-shaped holding groove parts 32, and having a taper-shaped tenon-like shape, are provided in the female metal fittings 3, 3 of each female connection part 4. An insertion hole 33 through which one end of the connection rod 7 is inserted is provided at least in one male metal fitting 5, a fixation nut 41 is fastened to a male screw part 40 of the end part of the connection rod penetrated through the insertion hole 33, thus anchoring the end part of the connection rod 7 to the male metal fitting 5. |
