Abstract
A concrete form system includes a plurality of concrete form board brackets. The plurality of brackets includes brackets for securing the concrete form board to a conventional type metal or wood concrete form stake without the need for nails. The plurality of brackets also includes concrete form board end brackets for securing the ends of adjacent concrete form boards together that allows for a range of angles to be formed between two adjacent concrete form boards from zero degrees to more than 180 degrees. The present invention also includes flexible sections of concrete forms configured to be coupled to the brackets that allow for forming curved concrete edges.
Claims19
A concrete form system, comprising:
- a plurality of concrete form board retaining brackets;
- a plurality of concrete form stakes;
- and
- at least one concrete form board, each of the plurality of concrete form board retaining brackets configured to retain the at least one concrete form board to a respective on of the plurality of concrete form stakes, each concrete form board retaining bracket having an upper and lower stake retaining portion that bias the respective concrete form stake against an outer surface of the at least one concrete form board, the upper and lower stake retaining portions each defining a recess that engages an outer surface of the concrete form stake to hold the stake relative to the bracket.
A concrete form bracket, comprising:
- a generally rectangular plate having a back wall, an upper wall depending from a top edge of the back wall at a first obtuse angle from the back wall and a lower wall depending from a bottom edge of the back wall at a second obtuse angle from the back wall, the top and bottom walls depending from a front side of the back wall so as to extend from the back wall in generally a same direction, wherein a distance between the first wall and the second wall at the back wall is configured to be approximately equal to a width of a concrete form board when the concrete form board is abutted against the front side of the back wall, wherein the upper wall extends upwardly and away from a top surface of the concrete form board when in a resting position of the concrete form bracket and wherein the lower wall extends downwardly and away from a bottom surface of the concrete form board when in the resting position;
- the upper wall defining a first recess having a first stake receiving opening along a portion of a first side of the upper wall and a first stake retaining portion configured to retain a first portion of an elongate concrete form stake therein;
- the lower wall defining a second recess having a second stake receiving opening along a portion of a first side of the upper wall and a second stake retaining portion configured to retain a second portion of the elongate concrete form stake therein when the elongate concrete form stake extends through the first recess and the second recess;
- the upper wall and lower wall being compressible toward one another when the upper wall is forced toward the lower wall and the back wall is abutting against a concrete form board positioned between the upper wall and lower wall to allow the stake to be positioned between the concrete form board and outermost edges of the first and second recesses;
- and
- the upper and lower walls being biased away from one another when not being compressed toward one another to hold the stake against a surface of the concrete form board.
