METHOD FOR MOVABLE FORMWORK PASSING THROUGH HOLE, AND DEVICE FOR MOVABLE FORMWORK PASSING THROUGH HOLE

WIPO Patent Application WO/2021/031354

A1

Provided are a method for a movable formwork passing through a hole, and a device for a movable formwork passing through a hole, which cannot affect the construction requirements and requirements for passing through a hole of under-deck self-propelled movable formworks. The method for a movable formwork passing through a hole comprises the following steps: assembling a movable formwork in place, adjusting the elevation of a form after pre-pressing is completed, and preparing to pour concrete after jacking and form assembly; curing the concrete after pouring is finished; hanging the whole movable formwork system by means of a front cross beam, a middle cross beam and a rear cross beam, dismantling a bracket and a bracket support leg, and moving a self-propelled trolley, the bracket and the bracket support leg to the next construction pier position; after same arrives in place, supporting the whole movable formwork system, dismantling a hanger system of the middle cross beam, the movable formwork falling as a whole, moving the movable formwork longitudinally under pushing of the self-propelled trolley, and the position of the rear cross beam being fixed; and moving the rear cross beam longitudinally and sliding same until the movable formwork, as a whole, longitudinally moves in place, and after same arrives in place, performing form assembly and jacking to conduct pouring construction of the next hole.
