FRAMING SYSTEM AND METHOD FOR MAKING PREFAB FAÇADE ELEMENTS WITH ATTACHED CONCRETE BEAM, AND THEREBY OBTAINED SELF-SUSTAINING FAÇADE SPAN ELEMENTS

摘要

The add-on framing system concerns a kit including a number of attachment elements which, depending on the stretcher structure to be made, are fixed together. Basic concept of the invention is a framing unit assembled from three angle-section elements (i.e. frame bench, stretcher holder and concrete holder), which can be extended with unit elements of the same type and a few accessories into a framing configuration adaptable to a desired shape and size of bearing façade elements as span-corbelling or span-projection elements comprising stretcher masonry with attached concrete beam. The invention makes it possible to prefabricate any kind of not-curved stretcher brickwork span structures attached to a concrete beam. The realisable stretchers may comprise 1, 2 or 3 horizontal faces but also 1, 2 or 3 faces included to 45°. The add-on kit further allows to produce concrete beams of desired section, size and three-dimensional design for integration in façade walls. In addition the invention offers the possibility to work on optimum shop level, which allows a quick and easy 'prefab' manufacture of corbelling façade stretchers simultaneously with accompanying concrete beam.
