The Life and the Work of the Prague Carpenter Michael Ranek
Bláha, Jiří
The designs of the low-cost roof trusses created at the end of 1820s by Prague carpenter of Hungarian origin Michael Ranek (1770-1842) form a sort of link between traditional trusses with collars and modern purlin constructions. The swift adoption of Ranek’s truss among carpenters was helped by the relationship of trusses to traditional collar systems, easier handling of beams with smaller profiles and last but, not least, its simplicity during fabrication and erection. During the course of the second half of the 19th century Ranek’s trusses, together with traditional trusses with collar beams, were forced out by new, progressive constructions, especially by the generally widespread purlin trusses.
