Abstract: A segmented end shape for an elongate, parallel-sided wooden web for a roof truss, suitable for use in the Turb-O-Web method of roof truss construction, is shaped as a series of three or more substantially straight facets to approximate a notional part circle, preferably a semicircle having an endpoint coinciding with an endmost point of said web. The end shape includes an irregular part polygon having an end point coinciding with the endpoint of the notional part circle, and wherein junctions between one or more adjacent facets of the polygon lie outside the notional part circle and a part of one or more facets lie inside the notional part circle.

Abstract: A method of cutting an elongate timber web which forms on each of two opposed ends thereof a tapered end shape including a series of at least four cuts at successive angles to approximate an arcuate convex end. The method includes the steps of performing first and second passes of the web through a saw having cutter groups at adjustably spaced apart locations, each cutter group having at least two cutters (101, 102, 103, 104) set to angles so that the cutters of each cutter group correspond to a subset of said series of cuts (201, 202, 203, 204) at a respective end of the web. The web is rotated between the passes, the rotation between passes and the cutter settings together result in a multi-faceted end cut.

Abstract: A plurality of wooden roof trusses for constructing a roof includes first and second wooden roof trusses. Each of the first and second wooden roof trusses includes a bottom chord and at least one upper chord obliquely disposed relative to the bottom chord. A first web is provided to the first wooden roof truss and a second web is provided to the second wooden roof truss. Each of the first and second webs has a tapered web end shape set without regard to a shape of a first and second joint, respectively, into which said tapered web end shapes of the first and second webs fit. The first and second webs are substantially identical in length and web end shape. The first and second webs are located at different positions in their respective first and second wooden roof trusses.

Abstract: Wooden roof trusses of the kind having a bottom chord (13) and at least one obliquely disposed upper chord (11) with webs connecting the chords by means of nail-pated joints, in which the webs are selected from a set of standard stock length webs (50), and the ends of the webs (49) are provided with a standard shape set without regard to the geometry of the particular web joints.

Abstract: A method for manufacturing a wooden roof truss having a bottom chord and at least one upper chord obliquely disposed relative to the bottom chord, with the upper chord and the bottom chord being connected by at least one web via nail-plated joints, the method including the steps of: designing a plurality of web designs having tapered end shapes at each end thereof and being of discrete web lengths at increments between minimum and maximum web lengths, the plurality of web designs, tapered end shapes and discrete web lengths being predetermined without knowing shape, pitch and span of said wooden roof truss to be manufactured; engineering a truss design for the wooden roof truss taking into consideration the plurality of web designs and the shape, the pitch and the span of the wooden roof truss to be manufactured by selecting at least one of the plurality of web designs for the truss design; and, assembling the upper and bottom chords and webs by securing joints created by the upper and bottom chords and th
