Lifting platform slab type ceiling slab support frame structure

Abstract

This invention discloses a ceiling panel support structure for lifting platforms, including a main boom mechanism, multiple extension boom mechanisms, multiple telescopic boom mechanisms, multiple extension boom positioning mechanisms, and multiple telescopic boom positioning mechanisms. The main boom mechanism has an elongated rectangular outline. Each extension boom mechanism is movably inserted at both ends of the main boom mechanism in its extension direction and positioned by the extension boom positioning mechanisms. Each telescopic boom mechanism is symmetrically pivotally connected to both sides of the main boom mechanism and positioned by the telescopic boom positioning mechanisms. This allows for the stacking and selective lifting of panels, assisting construction workers in supporting and positioning the panels, thereby reducing manpower and improving construction efficiency.
