Abstract:
A truss system comprising:(a) a wall having a generally planar upwardly facing surface;(b) a plurality of trusses, each truss comprising:an elongated upper chord member;an elongated lower chord member; anda plurality of interconnecting web members,(c) said upper or lower chord member being a single-piece roll-formed member having a generally U-shaped cross-section, said cross section comprising:a base; andtwo substantially parallel legs extending in the same direction from the longitudinal edges of said base at a substantially right angle thereto,(d) each of said legs comprising:a first outer face adjacent said base,a second outer face adjacent the distal end of said leg, said second cuter face being coplanar with said first outer face,an inwardly recessed face connecting said first and second outer faces, andan inwardly turned hem extending from said second outer face, said hem having an inner face coplanar with said inwardly recessed face;(e) a plurality of truss anchors located at spaced intervals along the length of said upwardly facing surface for transversely attaching a truss to a wall comprising:an elongated anchor member comprising in cross-section a base and two substantially parallel legs extending in the same direction from the longitudinal edges of said ease at a substantially right angle thereto, said anchor member being positioned on the upwardly facing surface of a wall with the length of the anchor member being substantially perpendicular to the length of the wall and less than the width of the upwardly facing surface of the wall with said legs extending upwardly to attachably receive a truss between said legs and transverse to said wall; andan elongated holddown strap comprising in cross-section a base and two substantially- parallel legs extending in the same direction from the longitudinal edges of said base at a substantially right angle thereto, said holddown strap being positioned transverse to said anchor member with said base adjacent the base of said anchor member and between the legs of said anchor member with the legs of said holddown strap extending downwardly adjacent the sides of the wall for attachment to the wall;whereby said holddown strap may attach said anchor member to the wall and said anchor member may be attached to a truss between said legs and transverse to the wall.
