Abstract
A retaining member for retaining spaced rigid members within a concrete matrix. A form for shaping the concrete matrix includes a base, a planar shaping surface for supporting the concrete matrix during its initial setting period, and a supporting member located on the rear side of the shaping surface. The retaining member includes a compressible hollow cylinder, preferably made of a foamed polymeric material. Portions of the retaining member are associated with the form and the supporting member, holding the retaining member in place to retain each rigid member in a parallel position to the other rigid members.
Claims6
An apparatus for forming a concrete matrix, comprising:
- a form for shaping the concrete matrix, the form including a horizontal base and a vertically extending platform having an outer surface and an inner shaping surface adapted to support the concrete matrix, the platform including a plurality of a first set of spaced apertures;
- a supporting member connected to the form and located on the side of the platform adjacent the outer surface, the supporting member including a plurality of a second set of spaced apertures aligned with the first set of spaced apertures;
- a plurality of spaced rigid members, each of the rigid members passing through one of each of the first and second sets of the spaced apertures;
- and
- a plurality of generally cylindrical and compressible retaining members, each of the retaining members having opposed ends and being adapted to partially enclose a rigid member, and each of the opposed ends being insertable through one of each of the first and second sets of the spaced apertures, the retaining members thereby being adapted to retain each of the rigid members in a generally fixed position relative to the platform.
