This utility model discloses a connection structure and device for precast concrete components. The connection structure includes a connector and at least one opening groove on the outer edge of an end plate on the precast concrete component. The opening groove penetrates the upper and lower surfaces of the end plate, and the connector is embedded in the opening groove. The connection device includes two end plates located at the ends of adjacent precast concrete components, and also includes the connection structure. The opening grooves on the outer edges of the two end plates of the two precast concrete components are vertically aligned, and the two end plates are connected together by the connector embedded in the two vertically aligned opening grooves. This utility model has a simple structural design, enabling rapid and reliable connection of multiple precast concrete components.
