Oval reinforced concrete tank erection with climbing formwork - uses climbing rail sections hinged for angular turning, with sliding guide shoes

摘要

Device for erecting thin-wall reinforced-concrete structures which are curved in plan and elevation, such as oval septic tanks, comprises a climbing scaffolding carriage movable on sectioned rails, and then removed. For structures with a pronounced curve in elevation, individual sections of the climbing rails (16) are hinged to each other so as to permit angular turns. The guiding media are in the form of sliding shoes (10, 12) led on the climbing rails. On the scaffolding carriages the inner long bars (4) may comprise individual sections (4, 4', 4") hinged together and mutually adjusted by hinged spindles (15). The rails can be precisely adapted to the height of concreting sections, with joints sited between these.
