The utility model discloses a clutch pressure plate with a good heat dissipation effect, and relates to the technical field of clutch pressure plates, the clutch pressure plate comprises a pressure plate body, the center of the pressure plate body is provided with a center hole, and the pressure plate body comprises an inner plate surface and an outer plate surface; a plurality of rivet holes are formed in the edge of the top of the pressing disc in a circular array mode. A thickening sleeve is arranged on the outer disc surface; a plurality of short protruding edges are arranged on the top of the thickening sleeve in a circular array mode, a plurality of arc-shaped heat dissipation through grooves are formed in the top of the thickening sleeve and the pressure plate body in a circular array mode, and all the short protruding edges are located between every two adjacent arc-shaped heat dissipation through grooves respectively. A long rib is arranged on one side, far away from the short rib, of the arc-shaped heat dissipation through groove; the problem that the clutch pedal makes contact with the clutch plate to slip when the clutch pedal is loosened is solved, the heat dissipation effect is achieved, deformation or cracking caused by temperature changes in the using process is avoided, and the service life of the pressure plate body is prolonged.

This invention belongs to the field of prefabricated building technology and discloses a prefabricated ceiling and its installation method. A supporting component is provided between the keel component and the panel. The supporting component includes a hanger connecting the keel component and a supporting rod for connecting the panel. The panel has a bearing groove formed by bending at least two opposite sides. The bearing groove extends along the edge of the panel and has an open structure design at the corner of the panel to facilitate the lateral sliding or insertion of the supporting rod. This invention provides an independent supporting component composed of hangers and supporting rods between the keel component and the panel, so that the support of the decorative panel no longer depends on the continuous passage of the secondary keel. When the secondary keel path encounters electromechanical pipelines such as fire sprinkler pipes, it can be directly bypassed without on-site cutting; while the panel obtains effective support through adjustable supporting rods.
