Abstract
A roof structure supporting a roof comprising a truss and a joist supporting the truss, the joist having two elongated wooden beam members on the bottom of the truss connected with beam tie members comprised of a pair of congruent truncated mirror image parallelograms forming hexagons with mutually facing and abutting portions. Each beam tie member is connected to outer sides of top and bottom elongated wooden beams and is adjacent to the next beam tie connected to outer sides of top and bottom elongated wooden beams. The tied beams allow use of smaller, less expensive beam members yet providing good truss support in a joist.
Claims20
A roof structure comprising:
- a roof truss made of beams having a width and a span;
- and
- a joist supporting the roof truss, that joist having,
- a pair of coextensive, spaced apart beams having parallel lengths, widths and a height, at least as long as the span of the truss, the beams spaced by a plurality of spaced apart blocks joined to the beams at intervals;
- a plurality of beam ties affixed along the length of the beams, the beam ties being formed by pairs of congruent irregular hexagons having a height that is approximately the same as the spaced apart beams, the pairs being symmetric truncated mirror image parallelograms forming the hexagons with mutually facing and abutting noses, wherein the extent of nose-to-nose abutment of the noses is at least one-third of the height of the irregular hexagons, whereby the beam ties form tiles that abut the beams and mutually abut in the space between the beams thereby adding strength and load support to the joist.

A truss assembly comprising:
- a wooden truss comprised of a pair of sloped top chords meeting at a peak and a web of beam members forming triangular structures connected to the top chords;
- and
- a wooden joist comprised of a pair spaced apart beams spaced by a plurality of spaced apart blocks joined to the beams at intervals and extending in parallel from one sloped top chord to the other;
- a plurality of beam tie members affixed along the length of the beams, the beam tie members being formed in symmetric pairs, each member comprising a symmetric truncated mirror image parallelogram forming an irregular hexagon, the tie members having mutually facing noses and a height that is approximately the same as the spaced apart beams, wherein the beam tie pairs are adjacent to each other appearing as tiles that abut the beams and mutually abut in the space between beams thereby adding strength and load support to the joist.

A roof structure comprising:
- a roof truss made of beams having a width and a span;
- and
- a joist supporting the roof truss, that joist having,
- a pair of coextensive, spaced apart beams having parallel lengths, widths and a height, at least as long as the span of the truss, the beams spaced by a plurality of spaced apart blocks joined to the beams at intervals;
- a plurality of beam tie members affixed along the length of the beams, the beam tie members being formed in symmetric pairs of congruent irregular hexagons having a height that is approximately the same as the spaced apart beams, the pairs being symmetric truncated mirror image parallelograms forming the hexagons with mutually facing and abutting noses, whereby the beam ties form tiles that abut the beams and mutually abut in the space between the beams thereby adding strength and load support to the joist.
2 more elements
A method of forming a joist for a truss comprising:
- stacking two parallel coextensive beams having a length spanning a truss dimension where support is designed, the beams having a non load bearing surface;
- joining the beams along the non load bearing surface, with ties fastened to the two beams, the ties being formed in symmetric pairs, each member of each of the ties comprising a symmetric truncated mirror image parallelogram forming an irregular hexagon and having mutually facing and abutting noses, the ties being tiled to have a corrugated shape along the beam length mutually abutting in the space between the beams thereby forming a truss joist, the corrugated tiles having a height that is approximately the same as the spaced apart beams.
