Arch and building construction

A building structure comprising a plurality of rigid arches, wherein:

• the arches comprise pairs of wooden panels;
• the pairs of panels each including first and second wooden trapezoidal panels;
• each of said first and second panels comprising a flat sheet of substantially rigid material having a trapezoidal configuration and including one long parallel side, one short parallel side opposite the long parallel side, and non-parallel sides connecting the ends of said long parallel side with the corresponding ends of the short parallel side, and a plurality of support members extending along the borders of the panel and being substantially perpendicular to the panel;
• the first and second panels of each pair of panels being contiguous, with the long parallel sides of the first and second panels being in an opposed, abutting relationship;
• and reinforcing means disposed between said first and second panels;
• and
• each pair of panels being in an abutting relationship with another of said pairs of panels, with the non-parallel sides of each of said abutting pairs of panels being in an opposed, abutting relationship with each other;
• the abutting pairs of panels collectively forming the arch;
• the arch being bounded on its sides by the short parallel sides of the panels forming the arch;
• and
• said arches being juxtaposed in a side-by-side relationship with the short parallel sides of the arches abutting corresponding short parallel sides in adjacent arches, said arches collectively forming said building structure.
