Concrete form brace and battering wedge
View Patent ↗A brace for securing concrete forms to a base has first and second triangularly-shaped sidewalls and a back wall extending between corresponding side edges of the sidewalls. A peripheral flange extends outwardly from the side edges of the sidewalls and the ends of the back wall and has apertures for facilitating fastening of the brace to the concrete forms and a casting surface. Advantageously, the brace can be formed as a unitary, molded component. A battering wedge is selectively attachable to the side edges of the sidewalls and cooperates with the brace to facilitate tilting the concrete form at an angle to the casting surface. The battering wedge is selectively frangible to permit use with braces of varying size.
1. A brace for securing concrete forms to a base, comprising:
first and second confronting sidewalls, each sidewall having a generally triangular shape, first and second adjacent side edges defining an included angle of approximately 90 degrees therebetween, and a third side edge disposed opposite said angle between said first and second side edges;
a back wall extending between said third side edges of said first and second sidewalls, said back wall having a first end proximate said first side edges of said sidewalls and a second end proximate said second side edges of said sidewalls;
said first and second confronting sidewalls and said back wall defining a generally empty cavity substantially enclosing at least one rib extending between said first and second sidewalls, wherein said brace is principally hollow; and
a flange portion extending outwardly from a periphery defined by said first and second side edges of said sidewalls and said first and second ends of said back wall, said flange portion including enlarged areas extending further outwardly from the intersections of said side edges and said ends of said back wall, said enlarged areas including at least one aperture for receiving a fastener therein.
2. The brace of claim 1 , wherein said rib is elongated and directed substantially perpendicular to said back wall.
3. The brace of claim 1 , further comprising a battering wedge selectively attachable proximate one of said first and second side edges of said sidewalls to tilt a concrete forming member at an obtuse angle with respect to the other of said first and second side edges of said sidewalls.
4. The brace of claim 3 , wherein said battering wedge comprises a first side configured to abut said flange portion of said brace, a second side configured to engage a concrete forming member, and a tapered profile extending between said first and second sides for tilting said concrete forming member with respect to the abutted flange portion of said brace.
5. The brace of claim 4 , wherein said battering wedge further comprises tabs formed on said first side and spaced to engage said flange portion adjacent said first and second sidewalls, said tabs including resilient fingers configured to engage said flange portion.
6. The brace of claim 3 , wherein said battering wedge includes at least one separable section that is selectively frangible along a pre-formed boundary from a remainder of said battering wedge so as to conform said remainder to said flange portion proximate one of said first and second side edges of said sidewalls.
7. The brace of claim 1 formed as a unitary, molded piece.
8. The brace of claim 4 , wherein said battering wedge includes voids formed in said second side.
9. The brace of claim 3 , wherein said battering wedge includes at least two pre-formed sections joined along adjoining sides and selectively separable along said adjoining sides, with at least one of said pre-formed sections being sized so as to correspond to the size of one of said first and second side edges of said sidewalls.
10. The brace of claim 3 , wherein said battering wedge includes at least two sections selectively separable across a pre-formed joint.
11. An assembly for forming concrete structures, comprising:
a casting surface;
a form member disposed on said casting surface to define a space for receiving poured, wet concrete, said form member having first side adapted to contact the concrete and a second side opposite said first side; and
a brace comprising:
first and second confronting sidewalls, each sidewall having a generally triangular shape with first and second adjacent side edges spaced to form an included angle of approximately 90 degrees therebetween and a third side edge disposed opposite said angle between said first and second side edges,
a back wall extending between said third side edges of said first and second sidewalls, said back wall having a first end proximate said first side edges of said sidewalls, and a second end proximate said second side edges of said sidewalls,
at least one rib extending between confronting side surfaces of said first and second sidewalls, and
a flange portion extending outwardly from a periphery defined by said first and second side edges of said sidewalls and said first and second ends of said back wall;
said brace coupled to said second side of said form member by said flange portion adjacent one of said first and second side edges, and coupled to said casting surface by said flange portion adjacent the other of said first and second side edges.
12. The assembly of claim 11 , further comprising a battering wedge disposed between said brace and said form member to thereby tilt said form member relative to said casting surface.
