There is provided a reinforcing steel structure for use in a concrete building wall. The structure includes one or more prefabricated, welded cages having vertical reinforcing bars. A plurality of continuous ties extends around the vertical reinforcing bars and a plurality of shear ties extends generally horizontally between the vertical reinforcing bars. Each welded cage is sized and shaped for shipping and said structure can be formed onsite from a plurality of said cages lapped together. Concrete is added to the reinforcing steel structure to form a concrete building wall.

There is also provided a reinforcing steel structure for use in a concrete building transfer or raft slab. The structure includes one or more prefabricated, welded beams. The prefabricated, welded beams have a top beam layer and a bottom beam layer, each having horizontal reinforcing bars, and a plurality of continuous ties extending generally vertically around the top and bottom beam layers. Each welded beam is sized and shaped for shipping and said structure can be formed onsite from a plurality of said beams lapped together. Concrete is added to the reinforcing steel structure to form a concrete building slab.

Various embodiments of the present disclosure provides a joint edge assembly and a reusable multiple position height adjuster and method of positioning and installing joint edge assembly and the reusable multiple position height adjuster for forming two adjacent concrete slabs and a joint between such adjacent concrete slabs.

A building component system including a rigid plastic form having an arched shape in each of two perpendicular vertical planes and having a plurality of protrusions configured to engage concrete poured on top of the rigid plastic form. The system also includes concrete poured on top of the form and cured to bind to the form at least at the plurality of protrusions, thereby forming an arched ceiling for a first story of a building and a flat roof or flat floor for a second story of a building.

A formwork system (100) includes a rebate board (105) having a generally L shaped profile in end view, the rebate board (105) having a first arm (110) and a second arm (120), the first and second arms (120) being angled at about 90 degrees relative to each other, the second arm (120) being securable to an upper portion of a formwork bottom board (200). The system (100) includes a brace (400) having a first engagement formation (410) configured to engage with the first arm (110), and a second engagement formation (435) configured to engage with a peg (220) or other fixed member.

A cement form assembly includes cement and a cement form. The cement form can include a ground facing surface extending horizontally on a ground support surface and a cement facing surface extending vertically and contacting the cement. An extension member extends outward from the cement form and includes a surface that extends the ground facing surface or the cement facing surface. The cement form and the extension member are each made, at least partially, of a foam material.

A support for installing facing materials such as ceramic tiles on a substrate, such as, floors, walls and ceilings. The support plate has a plurality of spaced apart raised portions and recesses in the plate material, and a plurality of openings extending through the top surface and bottom surface of the plate material. The openings exposing a mat layer attached to the bottom of the support plate. Support plates of the invention are used for tile installations between a substrate and tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the openings forming a continuous bond between the mortar, openings and mat layer to provide a strong bond between the support plate, mortar and the tiles.

The present invention concerns a reinforcing element for producing concrete components, a concrete component and corresponding production methods. The reinforcing element comprises a plurality of fibers and a plurality of holding elements which are connected to each other by the fibers so that the fibers can be stressed in their longitudinal direction by means of the holding elements. The fibers are fixed to the holding elements such that the fibers in the stressed state enter the holding elements in a substantially linear manner. This enables both a high degree of pretension and an efficient, reliable and thus cost-effective production of the concrete components.
