The present specification relates generally to concrete formwork, and specifically to a concrete form for the creation of a cantilever reveal in concrete stairs comprising a riser piece, a cove piece and a reveal piece. The cove piece includes a distal end and a proximate end, the proximate end positioned on a bottom end of the riser piece at a perpendicular angle to the riser piece and the reveal piece is positioned on the distal end of the cove piece projecting at a perpendicular angle to the cove piece, such that the reveal piece and the riser piece are parallel to one another. Also disclosed is use of one or more concrete forms to construct a cantilever reveal and a method of constructing a set of concrete stairs.

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.

A support for installing a porch post comprises a body. The body includes a ground end and a post end opposite of the ground end. A base is disposed on the ground end of the body. Two or more sidewalls extend from the base toward the post end. One or more open cross-members extend between the two or more sidewalls. The ground end may include a ground surface comprising grippers or stanchions extending away from the ground surface for securing the support with the ground.

A prefabricated concrete form with vertical spacers between fill forming cladding with cut-outs in the spacers having horizontal rebar received therethrough and received therein. Stand-offs are provided between the vertical spacers with vertical rebar received on the stand-offs. In one version, the stand-offs are attached to the horizontal rebar. In other versions, the stand-offs are attached to the spacers. A cut-out is formed in one of the claddings to form an auxiliary fill space on the outside of the cladding, which when filled with concrete, upon hardening, forms a ledge for supporting a stair structure.

The disclosure provides for pool step forms and related methods for forming steps in a pool formed by wall panels. The step forms may include a wall panel insert configured for insertion between adjacent pool wall panels. The step forms may include one or more step form brace configured to couple with the wall panel insert and, thereby, the wall panels. The step forms may include riser forms that from riser portions of the stairs when the step forms and riser forms are coupled. The pool stair forms may be filled with filling material to form tread portions of the stairs. The pool stair forms may include liner support members coupled to the step form braces and/or the wall panels that facilitate the coupling of a liner to the stairs formed by the pool stair forms and filling material.

A prefabricated stair modular assembly mold comprises a base, a step standard module, an upside module of a lower platform, an underside rotating module of a lower platform, an upside module of an upper platform, an underside rotating module of an upper platform, an underside common module, and an underside adjustment modules. Prefabricated stair molds of different dimensions are formed by means of locating holes provided in the assembling modules, and are then fixed by means of sliding holes at two ends. Further disclosed is a mounting method for said assembly mold. Said assembly mold has high positioning accuracy, and small accumulated error, improving the mounting efficiency of the prefabricated staircase mold.

Two or more sidewalls extend from the base toward the post end. One or more open cross-members extend between the two or more sidewalls. The ground end may include a ground surface comprising grippers or stanchions extending away from the ground surface for securing the support with the ground.
