Combined type formwork device with height-adjustable plate descending area

REN CHUNYU / LUO PAN

The invention relates to a height-adjustable combined type formwork device for a plate descending area, and belongs to the technical field of house building plate descending area construction. The height-adjustable combined type formwork device comprises a combined corner plate formed by splicing a plurality of corner plates, and the adjacent corner plates are fixedly connected through bolts and nuts; a lifting support is arranged at the lower end of the joint of every two adjacent corner plates, each lifting support comprises a rotary lifting structure, a screw base and a base connecting screw from top to bottom, and the lifting supports are fixed to a floor formwork through the base connecting screws during use. The rotary lifting structure comprises a rotary lifting sleeve, a rotary screw and a connecting structure from top to bottom, the tail end of the plug pin is inserted into the rotary lifting sleeve and fixedly connected with the rotary lifting sleeve, and the rotary screw is rotated to control the rotary lifting sleeve to ascend and descend so as to drive the plug pin and the combined corner plate to ascend and descend synchronously. The device provided by the invention can be suitable for descending plate areas with different sizes, can ensure the flatness of formworks and concrete in the descending plate areas, and avoids various quality defects after formwork removal.
