Claim:
A method for sequentially interconnecting structural members in rigid alignment, the method comprising the ordered steps of: constructing a structure by a single individual; positioning a first structural member of the structure having vertically side by side first and second parallel slots with the first and second parallel slots facing upward; lifting a second structural member of the structure having vertically offset third and fourth parallel slots above the first structural member with the third slot facing downward; lowering the second structural member and engaging the third slot of the second structural member with the second slot of the first structural member providing a stable structure; lifting a third structural member of the structure having vertically offset fifth and sixth parallel slots above the second structural member with the fifth slot facing downward; lowering the third structural member and engaging the fifth slot of the third structural member with the fourth slot of the second structural member providing a more stable structure; lifting a fourth structural member of the structure having vertically side by side seventh and eighth parallel slots above the third structural member with the seventh and eighth slots facing downward; lowering the fourth structural member and at the same time, comprising: engaging the seventh slot of the fourth structural member with the sixth slot of the third structural member; and engaging the eighth slot of the fourth structural member with the first slot of the first structural member providing a completed stable structure; wherein one of the first, the second, the third, and the fourth structural members includes ninth and tenth additional upward facing slots, and further including: lifting two fifth structural members having downward facing eleventh and upward facing twelfth parallel slots above the structural member including the upward facing ninth and tenth slots; lowering the fifth structural members over the structural member including the upward facing ninth and tenth slots; engaging the downward facing eleventh slots of the fifth structural members with the upward facing ninth and tenth slots; lifting a sixth structural member having downward facing side by side thirteenth parallel slots above the fifth structural members; lowering the sixth structural member over the fifth structural members; and engaging the thirteenth slots of the sixth structural member with the twelfth slots of the fifth structural members.
