TAPERED TRUSS

摘要

A tapered truss is provided. In one embodiment, the truss has a pair of base members configured to be attached to a top surface of a vertical support member. The truss may further have an upper pair of truss members and a lower pair of truss members. Each upper truss member each forms an acute angle with a respective base member and each lower truss member forms an obtuse angle from the respective base member such that the lower truss member is not parallel to the upper truss member. The truss may additionally include a ceiling joist member connected to each of the lower truss members. In one embodiment, the ceiling joist member is substantially parallel to the pair of base members.

1. A roof truss configured to be attached to a top surface of a vertical support member, the roof truss comprising:
a pair of base members, each base member having a bottom surface configured to be attached to the top surface of the vertical support member; an upper pair of truss members, each upper truss member having a longitudinal axis, and each upper truss member extending from a respective base member at an acute angle,
wherein each of the upper pair of truss members has a slope of about 4:12 to about 6:12 with respect to the base member; a lower pair of truss members, each lower truss member having a longitudinal axis, and each lower truss member extending at an obtuse angle from a respective base member such that the longitudinal axis of each lower truss member forms an acute angle with the longitudinal axis of a respective upper truss member,
wherein each of the lower pair of truss members has a slope of about 1:12 to 5:12; and a ceiling joist member having a first and a second end, the first end being connected to a first of the pair of lower truss members and the second end being connected to a second of the pair of lower truss members, wherein the ceiling joist member is substantially parallel to the pair of base members, and wherein the roof truss is constructed of steel.
