Abstract:
The quality and cost effectiveness of concrete construction is strongly influenced by the choice of the construction method. In the slipforming method, the stripped walls typically exhibit rough faces and often are deeply cracked. The advantages of working with the highly productive vertical conveyor such as the slipform may be lost, and the appearance of the concrete structure may not meet today's standards. With this disruption of quality, the volume of finishing labor and delivery materials increases, and so do other construction costs. These are some of the reasons that slip forming is not widely used, and is limited to special projects only. The idea behind the roller form system is to avoid the shortcomings of the slipforming method, and to offer the quality and precise geometry made possible by construction systems with immovable forms sheathing and the efficiency of working with the highly productive vertical conveyor of slipforms. The rollerform system can be applied to structures for which the conventional Slipforms method has been used, such as grain elevators, silos, flour mills, bridge piers, nuclear containment vessels, and multistory residential buildings.
