ABSTRACT:
An arch-shaped building structure is constructed from a multiplicity of relatively small but uniform pieces without the use of metal hardware or fasteners and without the use of conventional tools. Overlapping or offset cross members are disposed between substantially parallel stringer members wherein a given cross member supports a given stringer member and in turn is supported between a pair of stringer members parallel to the given stringer member. Ends of cross members offset from the given cross member are supported by said given stringer member, said offset cross members in turn supporting stringer members parallel to said given stringer member. Stringer members are received in upper slots in cross members, while end tabs of the last mentioned cross members are received in upper slots in stringer members parallel to the first stringer members. The weight of the structure places the cross members in interlocked compression such that no fasteners are required for holding the structure together.
