A system for securing modular building units to each other and a method for assembling structures using said method is disclosed. The disclosed system allows for modules to be connected to each other from an external position, without a person having to enter the modules to fasten components internally. The system and method may be used to build structures using prefabricated modules, avoiding significant amounts of onsite labor and drastically reducing the time required to erect structures.

The present invention relates to a formwork arrangement for forming a suspended concrete floor slab comprising a change in level in an underside thereof, a support bracket for use with such a formwork arrangement, and a method for employing the support bracket and formwork arrangement.

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.

The present disclosure provides a combined prefabricated reinforced concrete stair mold and a splicing method. The combined prefabricated reinforced concrete stair mold comprises a bottom mold platform (1), wherein an upper platform module (2), a tread module (3) and a lower platform module (4) which are spliced with one another are sequentially arranged on the upper surface of the bottom mold platform (1), and corner modules (5) are arranged between the upper platform module (2) and the tread module (3) and between the tread module (3) and the lower platform module (4); the tread module (3) comprises a tread upper surface mold (6) and a tread lower surface mold (7); and the tread lower surface mold (7) comprises a plurality of combined templates (8) formed by mutual splicing, and the tread upper surface mold (6) comprises a plurality of tread splicing pieces (9) formed by mutual splicing.

In one embodiment, a frame and stair system for engaging a wall includes multiple pad assemblies, a distal frame assembly, a lower proximal frame assembly, an upper proximal frame assembly, multiple stair assemblies, and multiple upper panel stair adapter brackets. A lower stair assembly is coupled with a left stair pad assembly, a right stair pad assembly, a left distal leveling pad, and a right distal leveling pad. A middle stair assembly is coupled with the distal frame assembly and the upper proximal frame assembly. An upper stair assembly is coupled with the upper proximal frame assembly. The upper proximal frame assembly is coupled with the lower proximal frame assembly. A left upper panel stair adapter bracket and a right upper panel stair adapter bracket are coupled with the upper stair assembly and are configured to engage an upper edge of the wall.

A method of producing an in-situ molded concrete object includes positioning a form on a substrate. The form can include a leg portion, a face portion, and a frangible portion. The frangible portion can connect the leg portion to the face portion. The method includes coupling the leg portion to the substrate to create a container open on at least one side. The method also includes pouring concrete into the container. The frangible portion can be fractured to separate the face portion from the leg portion.

A concrete form bracket for holding in place concrete forms. The bracket may have horizontally extendable arms with pivotable concrete form engaging surfaces. One or more of the horizontally extending arms pivot from a central area and are independently extendable/adjustable to engage a concrete form at multiple locations.

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.

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.
