Abstract: An inexpensive, expandable and easily erected shelter structure. The structure comprises a multi-sided roof supported by a single center upright, the roof being assembled using metal tubes and fittings. A center member is attached to the top end of the upright, the center member supporting a plurality of short tubes for receiving the corresponding ends of a plurality of elongated tube members. The other end of the elongated tube members are each connected to a fitting, each fitting also receiving the ends of two peripheral tubes. The other end of the upright is placed in a pipe sleeve anchored in the ground. A mechanism is provided to secure the roof to the center member. Two or more shelters can be easily interconnected to form larger structures with a minimum of ground support required.
