Sliding formwork: Features of construction technology
With a flexible disk of sliding formwork, the disk is deployed and if the jack rods are not able to perceive the load, they are deformed, while the geometric dimensions of the cross -section can change and get a circular displacement in the plan, which also took place in the practice of building.
From the above, we can conclude that the main details of the sliding formwork that impede the displacements are jack rods. Therefore, the jack rods should perceive the entire complex of loads. All loads on the jack rods are transmitted through the jack frames.
A vertical load from the weight of the formwork and cargo on it is transmitted to the jack rod, the moment that occurs in the jack frame from the temperature deformations in the construction of the sliding formwork, and the moment from the uneven distribution of the cargo.
