Abstract

A load-bearing three-dimensional structure including a skeletal structure formed by a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, wherein the sheet of material is bent along the bend lines into a box-section; and a reinforcing member configured for substantially surrounding a portion of the skeletal structure when bent into a box-section to reinforce the structural integrity of the skeletal structure. A method of manufacturing the three-dimensional structure is also disclosed.

Claims

1. A load-bearing structure comprising:

a three dimensional structure formed from a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, slits, or displacements and slits, the sheet of material bent along its bend lines into a box-section;

a reinforcing member formed by a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, slits, or displacements and slits, the reinforcing member configured for substantially surrounding a portion of the three dimensional structure to reinforce the structural integrity of the three dimensional structure; and

a gusset having peripheral tongue members, the gusset being configured to be wrapped along a peripheral edge by the three dimensional structure, wherein the three-dimensional structure includes grooves for receiving the tongue members, an inner surface of the reinforcing member contacts an exterior surface of the three dimensional structure, the reinforcing member substantially reinforces an outer shape of the three-dimensional structure, bend lines of the reinforcing member correspond to corners of the three-dimensional structure such that the reinforcing member fits the three-dimensional structure, and the sheet of material from which the reinforcing member is formed is bent along its bend lines to form a box section.

2. A load-bearing structure comprising:

a three dimensional structure formed from a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, slits, or displacements and slits, the sheet of material bent along its bend lines into a box-section;

a reinforcing member formed by a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, slits, or displacements and slits, the reinforcing member configured for substantially surrounding a portion of the three dimensional structure to reinforce the structural integrity of the three dimensional structure; and

a gusset having peripheral tongue members, the gusset being configured to be wrapped along a peripheral edge by the three dimensional structure, wherein the three-dimensional structure includes grooves for receiving the tongue members and wherein the sheet of material from which the reinforcing member is formed is bent along its bend lines to form a box section.

4. The load bearing structure of claim 2, wherein an inner surface of the reinforcing member contacts an exterior surface of the three dimensional structure.

5. The load bearing structure of claim 2, wherein the reinforcing member substantially reinforces an outer shape of the three-dimensional structure.

6. The load bearing structure of claim 2, wherein bend lines of the reinforcing member correspond to corners of the three-dimensional structure such that the reinforcing member fits the three-dimensional structure.

3. A load-bearing structure comprising:

a three dimensional structure formed from a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, slits, or displacements and slits, the sheet of material bent along its bend lines into a box-section;

a reinforcing member formed by a sheet of material having a plurality of bend lines, each bend line including a plurality of folding displacements, slits, or displacements and slits, the reinforcing member configured for substantially surrounding a portion of the three dimensional structure to reinforce the structural integrity of the three dimensional structure; and

a gusset having peripheral tongue members, the gusset being configured to be wrapped along a peripheral edge by the three dimensional structure, wherein the three-dimensional structure includes grooves for receiving the tongue members.

7. The load bearing structure of claim 3, wherein an inner surface of the reinforcing member contacts an exterior surface of the three dimensional structure.

8. The load bearing structure of claim 3, wherein the reinforcing member substantially reinforces an outer shape of the three-dimensional structure.

9. The load bearing structure of claim 3, wherein bend lines of the reinforcing member correspond to corners of the three-dimensional structure such that the reinforcing member fits the three-dimensional structure.
