Abstract
The elongated box frame structure of the present invention comprises a plurality of frame segments attached to at least one end piece. Preferably, two end pieces are attached, one at each end of the plurality of frame segments. The plurality of frame segments are attached to the end piece such that a column-like structure is formed. The inner space defined within the frame segments is substantially free of webbing. Instead, structural strength and stability is achieved by the attached end pieces. The end pieces of one elongated box frame structure are capable of removably connecting with the end piece of other similar elongated box frame structures to achieve varying framing heights and other dynamic configurations.
