Abstract: The structural wooden joist described comprises a lower chord, an upper chord spaced from the lower chord and a laminated panel structure joining the chords. This panel structure defines an uninterrupted surface from one end of the joist to an opposite end thereof and has opposite upper and lower edges joined to the lower and upper chords respectively. The laminated panel structure is formed of a series of elongated planks adhesively secured edgewise to one another and extending vertically between the lower and upper chords.

Abstract: The structural wooden joist described comprises an elongated lower chord, an elongated upper chord and an openwork web structure joining the chords and consisting of a series of connector members formed of inclined branches and adhesively secured to the lower and upper chords. Each branch of a connector member is formed of at least two planks having contiguous sides adhesively joined to one another. The connector members define a series of triangular openings in the web structure.

Abstract: The structural wooden joist described comprises a lower chord, an upper chord, a plurality of connector members spaced along the joists and extending between the upper and lower chords, a plurality of plates attaching the connector members to the lower and upper chords and a laminated panel structure mounted at each end section of the joist. Each panel structure extends from an opposite end of the upper/lower chords to adjacent a first of the plurality of attachment plates and defines an uninterrupted surface which is formed of a series of elongated vertical planks secured edgewise to one another whereby the joist has opposite ends which are trimmable to provide one of reduced width.

Abstract: The structural wooden joist described comprises a lower chord, an upper chord spaced from the lower chord and an openwork web structure joining the chords. The web structure includes, between opposite ends thereof, a series of horizontally spaced trapezoidal laminated panels defining a series of triangular spacings therebetween; each panel has opposite short and long sides adhesively joined to the lower and upper chords respectively and each panel is formed of short obliquely extending boards adhesively secured edgewise to one another.
