FRAMING FOR MAKING MANSARDS AND PROCESS FOR MANSARD-ROOFING EXTANT TERRACES BY USING THIS FRAMING

摘要

The invention relates to a four-slope framing for making mansards and to a process for mansard-roofing the building terraces in general by using this framing. The framing consists of more types of trusses adapted for certain positions occupied within the framing assembly, namely, some lateral half-trusses (5) whereon some current symmetrical trusses (7), some half-trusses for the lateral hip (6) of the roof are secured, some double symmetrical trusses (8), some end half-trusses (16), some long corner half trusses (17) and some short corner half-trusses (18) are fastened, the nodes between the vertical beams, diagonal members and truss bases being stiffened by means of some connecting plates (12) and the attachment to a z-shaped section attic (1) being made by means of angle stiffeners (11) by some bolts (13) and stranded nails (14). The framings are achieved by means of a process for mansard-roofing the extant building terraces.
