Abstract

A modified A-frame shell building 10 with a cementitious foundation having a pair of upstanding opposing stub walls 16, 18 that engage and support a plurality of trusses 50 disposed in spaced-apart relation for supporting a roof 58. Each truss comprises a pair of rafter beams with 45° beveled corners at opposing distal ends. The rafter beams 52 rigidly join together at a 90° angle at abutted corners 75 at distal ends 72, which defines a notch 106 that receives a ridge beam 62 extending across the trusses 50. The trusses include a collar beam 56 oppositely beveled at opposing distal ends 83, 85 and connected to the rafter beams 52 intermediate the distal ends 70, 72 of the rafter beams. Base plates 84 attached to the distal end 70 of the rafters 52 receive fasteners to engage the trusses 50 to the stub walls 16, 18. A roof 58 is defined by a deck 92 of tongue and groove boards covered by a insulative panel 93 and roofing materials such as shingles 94.

Dependent claims

A modified A-frame shell building, comprising:

a cementitious foundation defining a base and a pair of upstanding opposing stub walls that extend from the base to a predetermined height;
a plurality of trusses defining supports for a roof disposed in spaced-apart relation and attached to opposing stub walls, each truss comprising:
a pair of elongated rafter beams having side faces and bottom faces, each having a first and a second 45° beveled corner at opposing first and second distal ends, and the pair of rafter beams rigidly joined together at a 90° angle at the respective first distal ends with the first beveled corners of the pair of rafter beams abutted together;
the aligned first distal ends of the pair of rafter beams defining a trough;
an elongated collar beam oppositely beveled at opposing distal ends and abutted against bottom faces of the pair of rafter beams intermediate the distal ends thereof;
a pair of collar beam connector plates with a plurality of fasteners to rigidly connect the collar beam to the pair of rafter beams at the opposing distal ends;
and
a pair of angled end connector plates having intersecting surfaces and fastened on one surface to the side faces of the pair of rafter beams at the opposing second beveled corner and for being fastened on the other surface to an upper edge of a foundation wall;
an elongated roof ridge member extending between the spaced-apart trusses and received in the troughs;
and
a plurality of roofing members attached to the upper surfaces of the rafter beams.
