Abstract
A structural arch having one or more elongated tension members disposed within a shell or core at or near the lowermost edge of the arch, and one or more elongated compression members disposed within the shell or core at or near the uppermost edge of the shell. The core of the arch may be hollow, or optionally, lightweight filler material or filler members may occupy the core.
Claims24
A structural arch having a longitudinal axis, a lowermost longitudinal edge and an uppermost longitudinal edge, said structural arch comprising:
- at least one elongated tension member, said arch configured in cross-section transverse to said longitudinal axis such that the lowermost longitudinal edge defines a nadir, and wherein said at least one tension member is disposed at or adjacent said nadir;
- at least one elongated compression member, said arch configured in cross-section transverse to said longitudinal axis such that the uppermost longitudinal edge defines an apex, and wherein said at least one compression member is disposed at or adjacent said apex;
- and
- a hollow core.
A structural arch having a longitudinal axis, a lowermost longitudinal edge and an uppermost longitudinal edge, said structural arch comprising:
- at least one elongated tension member, said arch configured in cross-section transverse to said longitudinal axis such that the lowermost longitudinal edge defines a nadir, and wherein said at least one tension member is disposed at or adjacent said nadir;
- at least one elongated compression member, said arch configured in cross-section transverse to said longitudinal axis such that the uppermost longitudinal edge defines an apex, and wherein said at least one compression member is disposed at or adjacent said apex;
- and
- a core, wherein said core comprises a plurality of tubular members.
A structural arch having a longitudinal axis, a lowermost longitudinal edge and an uppermost longitudinal edge, said structural arch comprising:
- at least one elongated tension member, said arch configured in cross-section transverse to said longitudinal axis such that the lowermost longitudinal edge defines a nadir, and wherein said at least one tension member is disposed at or adjacent said nadir;
- further comprising at least one elongated compression member, said arch configured in cross-section transverse to said longitudinal axis such that the uppermost longitudinal edge defines an apex, and wherein said at least one compression member is disposed at or adjacent said apex;
- and
- further comprising a tensioning assembly to tighten said at least one tension member.
A structural arch having a longitudinal axis, a lowermost longitudinal edge and an uppermost longitudinal edge, said structural arch comprising:
- at least one elongated tension member, said arch configured in cross-section transverse to said longitudinal axis such that the lowermost longitudinal edge defines a nadir, and wherein said tension member is disposed at or adjacent said nadir;
- at least one elongated compression member, said arch configured in cross-section transverse to said longitudinal axis such that the uppermost longitudinal edge defines an apex, and wherein said compression member is disposed at or adjacent said apex;
- and
- a core composed of a rigid polymer foam;
- wherein the lowermost longitudinal edge is pointed or V-shaped in cross-section transverse to the longitudinal axis.
