PROBLEM TO BE SOLVED: To provide a junction structure for a precast foundation that suppresses deformation of a junction part and conveys tensile force effectively, even when a joint metal fitting is exposed to the tensile force.SOLUTION: A male-side joint metal fitting 11 having a protrusion 11a with a T-shaped horizontal cross-section is embedded in one of a pair of precast foundations 1A and 1B, edge surfaces of which are connected to each other. A female-side joint metal fitting 12 is provided on the other precast foundation 1B, the female-side joint metal fitting having a joint groove part 12a with a T-shaped horizontal cross-section into which the male-side joint metal fitting 11 is fitted. A curing-type filler 15 is filled in a gap between the joint metal fittings that have been fitted. A metallic filler member 14 is interposed in one or both of a gap 13a between a neck side surface of a head part 11aa of the male-side joint metal fitting 11 and an inner surface of the joint groove part 12a of the female-side joint metal fitting 12 opposite to the neck side surface, and a gap 13b between an opposite-the-neck side surface of the head part 11aa of the male-side joint metal fitting 11 and the inner surface of the joint groove part 12a of the female-side joint metal fitting 12 opposite to the opposite-the-neck side surface, the metallic filler member conveying a longitudinal direction load exerted on both precast foundations 1A and 1B.SELECTED DRAWING: Figure 9 |
