Assembly of prefabricated parts for door and window frames intended for buildings with clad façades

摘要

The present invention concerns an assembly of prefabricated parts made of cast concrete coloured in bulk, reworked on the surface to provide the appearance of natural stone. These parts are intended for making door and window frames, their thickness dimensions are standardised with the current construction materials (cement agglomerates, bricks, cellular concrete, shuttered concrete). These frames are designed for buildings whose facades are to be clad. The bonding of the stones is given by dummy joints and by positioning stones to project with respect to the rest of the block 2. The jamb posts are equipped with pin-shaped concrete irons 8, the threshold and the lintel 1 are equipped with recesses 3, the threshold is equipped with a drip 4, rabbets 6 on the jamb posts are intended to receive the pieces of joinery 6. The external edge of the jamb posts is profiled in order to achieve a good keying with the rest of the façade 7. IMAGE
