Concrete form assemblies having insulating foam panels are created using locking members embedded within the insulating foam panels and ties each having a pair of side rails for coupling two insulating foam panels together at a predetermined distance apart, the locking members and side rails being adapted so that either side rail can be coupled to either locking member and either of the ends of the rails and locking members can be toward the top or bottom of the assembly when the rails are coupled to the locking members.

A wall assembly for a building structure, uses (i) an inner shell cast in a first mold to define a first panel of concrete having a plurality of stiffener members embedded in the concrete so as to be at least partly exposed at the inner side of the panel, and (ii) an outer shell cast in a second mold to define a second panel of concrete having a plurality of stiffener members embedded in the concrete so as to be at least partly exposed at the inner side of the panel. The inner shell and the outer shell are mechanically coupled after casting to define a mold cavity between the inner sides of the panels. Field concrete can be cast into the mold cavity between the inner and outer shells once the wall assembly is mounted on site into position within the building structure.

A system and method for constructing an insulated concrete form (ICF) wall are provided. Vertically-oriented pairs of ICF foam panels of an ICF structure are erected above a footing, with vertical panel supports located along opposed vertical edges of each set of adjacent vertically-oriented panel pairs. An internal brace support, extending longitudinally along the structure, is installed between the individual panels of the panel pairs. Concrete is poured between the erected vertically-oriented ICF foam panels to complete the ICF wall.

A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other, where the first sidewall has a first passage extending therethrough, with a first insert received in the first passage of the first sidewall. The form also includes a first cross tie having opposed first and second ends, where the first sidewall is removably secured to the first end of the first cross tie and the second sidewall is secured to the second end of the first cross tie. A first fastener extends through the first passage and engages the first insert and the first end of the first cross tie to removably secure the first sidewall to the first cross tie. The second sidewall may be removably or non-removably secured to the first cross tie.

A collapsible formwork element, the element including: a pair of opposing side wall panels; and at least one connector member extending between the side wall panels, wherein the formwork element is movable between an expanded configuration, wherein the opposing panels are spaced apart, and a collapsed configuration, wherein the opposing panels are relatively closer together.

In a first aspect there is disclosed a support structure assembly (10). The support structure assembly includes a first wall panel (12) operatively associated with an opposing, spaced apart second wall panel. The first wall panel (12) including a channel (14) having two spaced apart channel walls (16) connected via a transverse channel base (18). The channel (14) encloses a resilient body (20).

A spacing connector used for assembling formworks and made up of at least one crosspiece, the crosspiece being connected, at both of its opposite ends, with at least one respective connection portion suited to make a connection with at least one panel of such formwork, the spacing connector also including at least one transpiration duct featuring two respective end openings, each of the end openings leading to a respective connection portion. Also disclosed is a formwork system including the spacing connectors.

In a one aspect there is disclosed a formwork wall panel (10) having an operative inner surface (12) to face towards an inner space to be filed with building material and an opposing operative outer surface (14) having a surface finishing component (16) secured thereto. The operative inner surface (12) of the formwork wall panel (10) includes a brace coupling formation (18) operatively adapted to engage a wall panel coupling formation (20) of a brace (22) operatively extending between the formwork wall panel (10) and an opposing second formwork wall panel.
