The invention discloses a novel combined flat plate hinged support. The novel combined flat plate hinged support comprises a lower supporting structure, a support bottom plate and a support ball. The support ball is fixedly connected to the support bottom plate through a support bearing plate. The support bottom plate is connected with a transition plate arranged under the support bottom plate through anchor bolts. The support bottom plate is provided with holes. The anchor bolts perpendicularly penetrate through the holes in the support bottom plate and are in plug welding connection with the transition plate. The transition plate is in welding connection with an embedded steel plate arranged on the lower supporting structure. Pressure springs are placed on the upper portions of the anchor bolts. Gaskets are placed at the lower ends of the pressure springs, and washers are placed at the upper ends of the pressure springs. Double-nuts are placed at the upper ends of the washers. The novel combined flat plate hinged support not only can effectively transmit horizontal shear force, but also can slide unidirectionally and bi-directionally, meets the position changing requirement and cannot slide down when abnormal position changing occurs.
