ABSTRACT:
A one-piece, durable plastic block for forming concrete structures wherein uncured concrete is poured into the block which has been laid in brick-like fashion with a plurality of similar blocks, and where the block becomes an integral part of the resulting concrete structure providing strength thereto. The block has a generally rectangular shaped housing with an open top and bottom. Lateral tensive strengthening is provided by a plurality of cross straps disposed across the open top and bottom of the block and include a connecting device to attach to overlying or underlying blocks. Each end wall of the block has a connecting device for attaching it to the end wall of an adjacently placed block. There is also a notch at the top and bottom of each end wall providing for the continuity of concrete between blocks and to allow the installation of reinforcing bars across this interface. The block is made of a plastic material which is sufficiently durable as to allow it to be as thin as possible and still strong enough to retain the uncured concrete. One version of this invention is foldable such that a first side wall and end wall pair will lie practically flat against the second side wall and end wall pair to facilitate packaging, shipping and storage. Another version of this invention allows attachment of facing materials either by a series of perforations to allow the application of plaster-type materials, or a pin and hole arrangement for panel-type materials.
