SYSTEM FOR CONSTRUCTION OF MONOLITHIC CONCRETE TANKS AND SILOS

摘要

A scaffold mechanism for constructing a cylindrical building, such as a concrete silo, with a horizontal platform supported on a plurality of fixed arms having telescopically extensible ends with the platform vertically supported on triangularly positioned peripheral vertical ground supported masts having pins placed in openings for locking the platform at vertical increments and having hydraulic lifters on each of the masts for raising the platform for each pouring of new concrete courses. A ground supported main central mast extends up through the platform and supports, at its upper end, cranes which are pivotally supported on the main mast for lifting the forms to reset positions, elevating concrete to a bucket cart which rolls peripherally around on the platform, or suspending and rotating hoses used for the placement of concrete when pumping is used in lieu of elevating concrete to a bucket cart. A hydraulic motor driven pump is carried on the platform for operating the elevating mechanism, the cart and the cranes.
