Abstract: A generally U-shaped channel member is positioned on top of the top surface of a plurality of foam plastic blocks in a horizontal wall segment, and vertically aligned concrete confining openings are formed through both the channel member and the plastic blocks. Concrete or the like is poured into the U-shaped channel and is funneled therefrom into the vertical openings. Once the concrete sets as a rigid supporting structure, the U-shaped channel is permanently retained in the wall structure. The U-shaped channel member is employed for attaching means to the exterior of the completed wall structure. Additional horizontal segments of the wall structure are formed by placing another horizontal layer of plastic blocks and a U-shaped channel member on top of the previously completed horizontal segment.
Abstract: An extendible structure of the invention is constructed by connecting the radially projecting legs of the spacer with differing longerons through the joints, and then fastening one joint with adjacent another joint at a diagonally opposed position with a bridle. In the extended state of the structure, the spacers are within a plane which is substantially perpendicular to the direction of extension of the structure and the bridles are extended in the diagonal lines between the adjacent joints to thereby form the longerons in a mast-shaped three-dimensional structure, while, in the collapsed state of the structure, the longerons are collapsed in a loop form and the spacers are laid one upon another inside the loop formed by the longerons to thereby produce a cylindrical form in its outer appearance.
Abstract: This disclosure relates to a clip for securing together adjacent collapsible, expandable, self-locking, self-supporting structures which include a plurality of pairs of crossed rod elements pivotally joined in scissored fashion to each other and to hubs having openings therein, the structures having at least one hub of each section adjacent each other, and the clip having at least two stems with each stem being interlockingly received in an associated opening of the adjacent hubs to thereby secure the structures to each other in any one of a plurality of different configurations.
