メントの継手構造。[Claims for Utility Model Registration] One of a pair of concrete segments to be connected to each other is provided with a recess near the joint end surface, an insertion hole is formed that penetrates from the recess toward the joint end surface, and the other An insertion hole is formed in the concrete segment extending inward from the joint end surface, and a bottomed cylindrical reinforcing member is embedded in the inner wall of the insertion hole to cover at least the vicinity of the tip of the insertion hole. A part of the inner wall is provided with a substantially cylindrical engagement member having multistage engagement protrusions that protrude in a serrated manner toward the tip of the insertion hole. At the same time, a pin is inserted through the communicating insertion hole, and this pin protrudes in a sawtooth shape from the outer periphery of the distal end toward the base end of the engaging member. The pin has a multistage engagement protrusion that engages with the engagement protrusion of the pin, and has a threaded portion on the outer periphery of the proximal end, and the engagement protrusion at the tip of the pin engages the engagement member. A concrete segment joint structure characterized in that the pair of concrete segments are connected by engaging the protrusion and screwing the threaded portion of the base end with a nut on the inner surface of one side of the recess. .
