Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a highly efficient and stable formwork support structure for the horizontal joint at the bottom of composite floor slabs. Background Technology

[0002] Composite floor slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs offer good overall integrity, with smooth upper and lower surfaces, facilitating finishing processes. They are suitable for high-rise buildings and large-span buildings requiring high overall rigidity. Furthermore, the prefabrication process significantly shortens the construction period, leading to their widespread application in engineering projects.

[0003] Chinese Patent Publication No. CN 222909461 U discloses a composite floor slab support device, including a side plate, a transverse support plate, a longitudinal support plate, a lifting plate, a guide member, a composite floor slab support plate, a driving device, and a locking member. The side plate is detachably connected to an embedded part system. The transverse support plate extends horizontally and is vertically fixed to the side plate. Two longitudinal support plates are spaced apart, each extending vertically and vertically fixed to the upper side of the transverse support plate, and both longitudinal support plates are fixedly connected to the side plate. The lifting plate is located above the two longitudinal support plates. At least two of the two longitudinal support plates and the side plate are connected to the lifting plate by a guide member. A composite floor slab support plate for supporting the composite floor slab is provided on the upper side of the lifting plate. The driving device is arranged on the transverse support plate between the two longitudinal support plates, and the output end of the driving device is used to drive the lifting plate to move vertically away from or towards the transverse support plate under the guidance of the guide member. A locking member is provided on the transverse support plate for locking the lifting position of the lifting plate. The embodiments of this application can adjust the height of composite floor slabs, with a reasonable structure, simple operation, easy disassembly, and reusability, thereby improving construction efficiency, reducing costs, and enhancing the overall aesthetics after construction.
