Patent ID: 8832917

Claim:
A method for sequentially interconnecting structural members in rigid alignment to construct a stable structure, the method comprising: positioning a first structural member having vertically side by side first and second parallel slots and a multiplicity of vertically and horizontally spaced apart spacers on an inside surface, with the first and second parallel slots facing upward and the spacers extending towards an interior of the stable structure; lifting a second structural member having vertically offset third and fourth parallel slots and the multiplicity of spacers above the first structural member, with the third slot facing downward and the spacers extending towards the interior of the stable structure; lowering the second structural member and engaging the third slot of the second structural member with the first slot of the first structural member providing a stable structure; lifting an additional structural member having vertically offset downward and upward facing parallel slots, and the multiplicity of spacers, above one of the engaged structural members having an open upward facing slot, with the downward facing slot of the additional structural member aligned with the open upward facing slot of the engaged structural member, and the spacers extending towards the interior of the stable structure; lowering the additional structural member and engaging the downward facing slot of the additional structural member with the open upward facing slot of the engaged structural member, providing a more stable structure; engaging additional structural members with the engaged structural members until only a single final structure member remains unengaged; completing a first room of the stable structure by lifting the final structural member having vertically side by side downward facing parallel slots, above two of the engaged structural members having open upward facing slots; lowering the final structural member, and engaging each of the downward facing slots of the final structural member with the open upward facing slots of the engaged structural members; and attaching inner panels to the spacers to provide an interior wall for the stable structure.
