Wood I-Joist And Method Of Fabricating The Same
US Patent:
4638619, Jan 27, 1987
Filed:
Dec 19, 1983
Appl. No.:
6/563181
Inventors:
David C. Fischetti - Cary NC
International Classification:
E04C 330
US Classification:
52729
Abstract:
The present invention entails a wood I-joist and method of manufacturing and fabricating the same. Structurally the wood I-joist comprises a web assembly secured between two wood flange assemblies. Each wood flange assembly comprises a plurality of individual wood members secured together in end-to-end relationship to form an elongated wooden member subassembly that extends the entire length of each respective wood flange assembly. A series of wood member subassemblies are glued together in side-by-side relationship to form a respective wood flange assembly. In forming each wood flange assembly, an inner side is provided for receiving the web assembly. Each inner side is formed by providing an opening or void that stretches the entire length of each wood flange assembly to secure the web assembly within this opening or void. There is provided a number of wood wedge members which are driven into the web receiving opening, between each side of the web and an adjacent side of the wood flange assembly. The presence of these wood wedge members binds the web assembly and secures the same within the respective wood flange assemblies.
Laminated Timber Structure For Use As A Stud, Joist Or Post Substitute
US Patent:
4568577, Feb 4, 1986
Filed:
Jan 4, 1982
Appl. No.:
6/336518
Inventors:
David C. Fischetti - Cary NC
International Classification:
B32B 2100
US Classification:
428 33
Abstract:
The present invention entails a laminated timber structure comprised of a plurality of elongated laminated timbers laminated together in side-by-side relationship to form an elongated timber structure. The cross sectional area of the respective elongated timbers are of a generally uniform shape and size, with the cross sectional area being preferably square such as one-half inch by one-half inch. This enables standard size laminated timbers such as two by four, two by six, four by four, to be formed. In forming the laminated timber structure of the present invention, the respective elongated timbers are disposed in side-by-side relationship and glued along the sides of the timber as well as across the ends, giving rise to both edge and face joints. Moreover, at selected areas in the cross sectional area of the laminated timber structure of the present invention, there can be provided elongated voided areas formed by gluing a plurality of the timbers together in a surrounding configuration so as to define the elongated voided area internally within the surrounding timbers.
