Rapid erection concrete building components shuttering - using inverted U-sectioned inner self supporting frames easily adjusted and moved

摘要

Shuttering formwork for building components consists of one or more inner shuttering frames (1-3), which are self-supporting, with an inverted U-shaped cross-section. Devices are provided for altering the height and width of these, and for levelling them out and transporting them away. Such a frame is moved to the erecting site on elevating supports with rollers and, raised and levelled out at the height required: it is connected to other shuttering components, to form hollow spaces for filling with concrete these are sealed on the facing sides of the walls and/or ceilings to be erected, then concrete is poured in, and set, if necessary with acceleration by heating or insulation.
