Abstract
There is a truss structure, assembly and method of manufacturing a truss with a span L and a beam depth H. The truss having a main part includes a substantially planar top chord with a longitudinal centerline and webs connecting between the top chord and a bottom chord. The top chord is separated from the bottom chord by the webs. There is a top chord node where each web intersects with the centerline of the top chord and a bottom chord node where each web meets the bottom chord. At least two of the top chord nodes coincide with one another along the top chord. In use, the elements of the main part are in compression and the bottom chord includes a tension member.
Claims26
A truss structure with a span L and a beam depth H, the truss having a main part comprising:
- a planar top chord with a longitudinal centerline and webs connecting between the top chord and a bottom chord, the top chord being separated from the bottom chord by the webs,
- there being a top chord node where each web intersects with the centerline of the top chord and a bottom chord node where each web meets the bottom chord,
- wherein
- at least two of the top chord nodes coincide with one another along the top chord;
- wherein, in use, the elements of the main part are in compression and the bottom chord comprises a tension member;
- and
- wherein the material of at least the webs is a 3D-printed additive material.

A method of manufacturing a truss structure with a span L and a beam depth H comprising the steps of:
- providing a planar top chord with a central main axis and a centerline;
- and
- printing a bay comprising a pair of normal and diagonal webs above and along the centerline on to the top chord, the webs being separated by a panel,
- wherein the printing of the bay is complete when the normal and diagonal webs intersect one another.
