Wall beam prefabricated structure

The utility model provides a wall body beam prefabricated structure which comprises a concrete beam body, the lower side of the concrete beam body is fixedly connected with a supporting plate, the upper side of the supporting plate is provided with four threaded rods, each threaded rod penetrates through the concrete beam body and extends out of the upper side of the concrete beam body, and the upper side of the concrete beam body among the four threaded rods is provided with an arc-shaped arch. Each threaded rod is connected with a locking nut in a threaded fit mode, a flat plate is arranged between each locking nut and the corresponding arc-shaped arch, and four connecting holes are formed in the lower sides of the two ends of the concrete beam body. The supporting device has the advantages that the flat plate is tightly pressed on the upper side of the arc-shaped arch of the concrete beam body through the four locking nuts, so that the flat plate deforms along with the arc-shaped arch and arches upwards, t
