Prefabricated part for assembled building construction

The invention relates to the field of prefabricated parts and discloses a prefabricated part for assembled building construction. For the problem that the erection of an assembled prefabricated canopyframe wastes time in the prior art, the following scheme is provided; the prefabricated part for assembled building construction comprises four supporting columns and two top beams; two connecting plates are connected to the two sides of the four supporting columns through connecting mechanisms in a sliding manner; fixing piles are fixed at the bottoms of the connecting plates; fixing rings are rotationally connected to the tops of the two connecting plates; two connecting cylinders are fixed at the bottoms of the two top beams; one ends of the four supporting columns respectively extend intothe four connecting cylinders; and the four connecting cylinders are respectively in detachable connection with the four supporting columns. The prefabricated part for assembled building constructionhas the advantages that th
