Abstract
Apparatus, systems and methods for holding a riser of a step form in position when pouring concrete to make a stairway are provided. The apparatus is a bracket that may include a riser support for coupling with the riser. The bracket also includes a top support. A first end of the top support may be connected to the riser support for providing support to the riser support. The bracket may additionally include a back support for providing support to the riser support. The back support may be coupled to both the riser support and the top support such that an area enclosed by the riser support, the back support and the top support is a triangle. At least two of the riser support, the back support and the top support may include fastening plates for coupling with an external support.
Claims11
A bracket for holding a riser of a step form in position when pouring concrete to make a stairway, the bracket comprising:
- (a) a riser support for coupling with the riser, the riser support comprising a surface for bearing against the riser;
- (b) a top support, a first end of the top support coupled to the riser support, for providing support to the riser support;
- (c) a back support for providing lateral support to the riser support, the back support coupled to both the riser support and the top support such that an area enclosed by the riser support, the back support and the top support is a triangle;
- (d) wherein at least two of the riser support, the back support and the top support comprise fastening plates for coupling with a support extending from a top of the stairway to a bottom of the stairway, each of the fastening plates being parallel to a plane defined by the triangle and positioned to contact the support.
A bracket system for constructing a stairway form, the bracket system comprising:
- (a) at least one pair of brackets for holding a riser of the stairway form in position, with each bracket comprising:
- (i) a riser support for coupling with the riser, the riser support comprising a surface for bearing against the riser;
- (ii) a top support, a first end of the top support coupled to the riser support, for providing support to the riser support;
- (iii) a back support for providing lateral support to the riser support, the back support coupled to both the riser support and the top support such that an area enclosed by the riser support, the back support and the top support is a triangle;
- (iv) wherein at least two of the riser support, the back support and the top support comprise fastening plates for coupling with one of a first support and a second support, each of the first support and the second support extending from a top of the stairway to a bottom of the stairway, each of the fastening plates being parallel to a plane defined by the triangle and wherein the fastening plates on a first bracket of the pair of brackets are positioned to contact the first support, with the first support located on a first side of the pair of brackets, and wherein the fastening plates on a second bracket of the pair of brackets are positioned to contact the second support, with the second support located on a second side of the pair of brackets.
