Abstract:
1. A retention apparatus for stabilizing laterally spaced first and second form members defining a cavity for receiving concrete therein and arranged on a supporting surface such as the ground to define said cavity prior to and during the pouring of the concrete and for supporting the wet concrete contained in said cavity for an indeterminate interval following the pouring of the wet concrete, said form members having inside surfaces defining said cavity and confining said concrete and outside surfaces, said retention apparatus comprising: a) a first elongated metallic stake having a head at one end and a point at the opposite end and adapted to be embedded over an indeterminate length in said supporting surface with an intermediate portion of said elongated stake abutting the outside surface of a first associated form member; b) a second elongated metallic stake having a head at one end and a point at the opposite end and adapted to be embedded over an indeterminate length in said supporting surface on the opposite side of said cavity from said first elongated metallic stake, said second elongated metallic stake having an intermediate portion abutting the outside surface of said second form member; c) a first set of a multiplicity of through-bores in each of said first and second elongated stakes, said through-bores of said first set in each elongated stake being spaced along said elongated stake and extending through said stake perpendicular to the outside surface of the associated form board abutted by the intermediate portion of each elongated stake; d) a second set of a multiplicity of through-bores in each of said first and second elongated stakes, said through-bores of said second set being spaced along said elongated stake intermediate the through-bores of said first set of multiple through-bores and extending parallel to the outside surface of the associated form member abutted by the intermediate portion of each elongated stake and extending perpendicular to the associated first set of multiple through-bores; e) a nail for driving through each of a selected number of through-bores of said first set of multiple through-bores in each of said first and second elongated stakes and into the associated abutting form member to detachably attach said form members to the associated abutting stakes; f) a nail slidably and detachably disposed in a selected one of said second set of a multiplicity of through-bores in each of said first and second elongated stakes so that the nail in each stake lies parallel to the nail in the opposite stake and parallel to the outside surface of the associated form member, each nail in each stake including projecting end portions thereof that extend in opposite directions on opposite sides of said elongated stake in which it is detachably supported; and g) means extending transversely across and above said form members and detachably engaged at opposite ends to said projecting end portions of said nails that extend in opposite directions on opposite sides of said stakes and which nails are slidably and detachably disposed in said elongated stakes on opposite sides of said form members.
