Abstract
Abstract This specification discloses a foundation strip that is used to locate two vertical mold panels in spaced relation on a base and maintain the panels in these positions during the molding of a concrete wall. The strip is an integral one-piece member of plastic and is structurally designed to incorporate the necessary properties of strength and rigidity into the strip when made of plastic, as compared to metal.

Claim 1
Independent Claim
208 words
In a foundation strip For locating and holding in position a pair of spaced mold panels on a base for the molding of a concrete wall, said strip being of plastic: a. a main body portion of elongate, rectangular shape presenting end and side edges; b. said main body portion being formed with an aperture between said end edges, said aperture being adapted to receive a nail which secures the strip in position on said base; c. a pair of outer flanges, each of which is integral with the said main body portion and which upstands therefrom at a distance spaced from an end edge; d. a supporting member in the form of a triangularly shaped web for each of said outer flanges, each supporting member being located midway the side edges of said main body portion and having one edge integral with the flange which it supports, and another edge integral with the main body portion between the flange which it supports and the adjacent end edge of the main body portion, and e. a pair of inner flanges each of which is spaced from an outer flange a distance equal to the thickness of one of said mold panels and integral with said main body portion.
