Abstract: An elongate formwork element for use in the construction of a concrete floor is disclosed. The formwork element includes a base wall (15) and a side wall (17) extending from one side edge of the base wall so that the element is generally L-shaped in transverse section.

Abstract: The present invention relates generally to a bracket (1) which in a preferred embodiment is formed of a single strip of sheet metal comprising an affixture portion or a flat wall frame affixture portion (2) and an anchoring portion or a flat base affixture portion (3) having temporary spacing means in the form of four outwardly protruding teeth (4) projecting from a lower face of the base affixture portion (3). The wall frame affixture portion (2) is secured via affixture fasteners (7) to a structural member of a wall frame in the form of a wall stud (8). The base of affixture portion (3) is secured against the upper surface of a building element or a concrete floor slab (6). In assembly, the teeth (4) provide a temporary gap between the lower face (13) of the base fixture portion (3) and the upper surface of the base or concrete floor slab (6). The bracket (1) is secured to the concrete slab (6) via a bolt or shank (9) pre-anchored to the base (6).

Abstract: A tie bracket for linking adjacent end studs of two or more stud wall subframes extending at an angle to each other, comprises a shaped element of sheet metal which includes a generally polygonal centre portion (12) defining at least three margins (14) intersecting at respective corners, for being accommodated between the end studs. A plurality of tabs (20) project respectively from at least two of the margins for engaging respective apertures in the end studs. Each tab is of a length in the direction of projection greater than its width and of broadly similar order to the lengths of the longer of said margins. Respective formations (28) are provided in each of the tabs to define alternative bending lines (29) spaced in the direction of projection.
