Fabricated pile and bearing platform joint connecting structure and construction method

The invention belongs to the technical field of fabricated pile-bearing platform connection, and discloses a fabricated pile and bearing platform joint connection structure and a construction method. The connecting structure comprises a joint connecting column, two L-shaped positioning plates and two prefabricated bearing platforms. Wherein the node connecting column is configured to be connected to a precast pile, and the two L-shaped positioning plates are arranged in a spaced mode in the first horizontal direction and are both arranged at the two ends of the node connecting column in a sliding mode. A containing cavity is formed in the joint connecting column, a driving mechanism is arranged in the containing cavity, and each L-shaped positioning plate is connected to the output end of the driving mechanism. Under driving of the driving mechanism, the two L-shaped positioning plates can move in the direction close to each other at the same time, then the two prefabricated bearing platforms arranged on the
