Abstract

Current timber trusses are mainly made using steel fasteners, nail plates, or dowels with slotted plates. Glued timber trusses are applied commercially by two companies: German PERI produces trussed joists for concrete casting and Canadian Barret Structural makes trussed joists for residential floors. These trusses are based on finger joints made using a cursor. Recently, a Finnish company Teeri-Kolmio Oy started manufacturing glued trusses for residential floors with the joint processed using a saw blade. The such joint enables deep chord routings up to through the chord, long fingers, large web-chord glue areas, minimal timber splitting, and high resistance and reliability. There are further special characteristics. Top chord support is possible without hangers. The truss can be manufactured as a long billet, stored at lumberyards, and cut for actual needs. The truss can be manufactured without open routings and water pockets. The truss is strong and reliable and can be applied for the roofs of commercial buildings up to about 30 m spans. Our study shows that the trussed roof is more cost-effective than the glulam roof which opens a promising new business possibility.
