Formwork System For Making Circular Tanks Without Through Bars
Solutions adaptable to any requirement, work site and use conditions to erect circular tanks with a radius of up to 40 meters. Produced in the Italian mechanical engineering centre of Breganze, they assure perfect structure tightness and combine quality, versatility of accessories and long service life, in compliance with the high site safety standards.
The BioGas System permits the construction of circular tanks with a minimum radius of 7 meters and ensures the perfect tightness of the structures without having to use tie rods. It consists of completely metallic panels with reduced dimensions and whose surface turned towards the cement pour, calendered with a very large curvature radius, is concave or convex depending on whether the panels are for shoring up the inner face or the outer face of the circular pour. The horizontal sides of the panels are flat and have holes for the vertical tightening accessories or the parapet uprights. As well as fixing to the adjacent panel by means of wedges, the inside panels are connected by fixed or adjustable props to vertical struts, creating a support structure suitable for supporting the pressure of the concrete during the pour stage. Furthermore, it creates an adequate and safe working platform for the workers during the pour casting.
