Tower structures: features and nuances
Considering the calculation of the tower structure in the stage of its construction, you can accept the same calculated scheme. In this case, the depth of the upper sections can be even larger, since freshly laid concrete has the property of creep.
The sliding formwork, relying on the tower structure by means of jack rods, is rearranged by a flexible or hard disk on the system of numerous racks. Therefore, the hard disk of sliding formwork can rotate from torque around the axis, without changing its shape, if it resists horizontal loads.
In this case, the jack rods are deformed (bend), concrete walls following the sliding formwork, without changing the geometric sizes in the cross section, are shifted in plan in the form of the so -called corkscrew, which is often found in construction practice.
