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.

A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

Disclosed is a form work system (100) that comprises first (102a) and second (102b) building formwork components that are connected by a building formwork connector (104). The connector (104) comprises a moveable portion (128) that is moveable from a closed position to an open position. In the closed position, one or more sidewalls of the connector (104) define a cavity (144) for receipt of cementitious material. The cavity (144) of the connector (104) is located with respect to cavities (110) of the first (102a) and second (102b) formwork components. In the open position, access is provided to the cavity (144) of the connector (104).

An insulating concrete form system for the construction of insulated concrete walls, floors or roofs, the system comprising: at least one first panel; at least one second panel configured to be placed opposite to the at least one first panel, and a plurality of spacers configured to interconnect the at least one first panel and the at least one second panel while defining a space between the at least one first panel and the at least one second panel. A method for constructing a concrete wall, floor or roof, as well as additional embodiments of the system and method, are provided herein.

There is provided herein a modular be fabricated wall system which has a number of interlocking modular prefabricated wall sections. Each wall section has opposing planar face boards and a number of orthogonal spacers adhered to respective inner faces of the face boards for bracing the face boards apart. Vertical joiners may be adhered to inner edges of each face board for quickly and easily vertically slotting together adjacent wall sections in a row. The present wall sections are low-cost in that both the face boards and the orthogonal spacers may be cut from low-cost board, such as fibre cement board. Specifically, the face boards and the spacers may be both made from fibre cement board and the spacers may be glued perpendicularly between inner surfaces of the face boards. As such, the present wall sections may be manufactured without fasteners, ties and the like.

A shearwall assembly includes a first concrete and a second concrete column and a protrusion extending from a connection end of the respective concrete columns. Each protrusion has two side surfaces and a center surface. A pair of horizontal slab panels are positioned between the respective connecting ends of the first and second concrete columns and abutting the two side surfaces of the respective protrusions. A horizontal reinforcement extends from the center surface of the respective protrusions and between the respective trusses. Concrete is poured at a volume formed between the pair of horizontal slab panels and the first and second concrete columns.

A panel (6) is disclosed for use in construction. The panel (6) comprises opposing surfaces (6A, 6B) that extend between first and second opposite ends (7A, 7B). The panel (6) also comprises a plurality of parallel (e.g. sawtooth) ridges (7). The ridges (7) are provided on at least one of the opposing surfaces (6A and/or 6B). The ridges (7) extend along and adjacent to a first of the opposite ends (7A or 7B) of the panel for at least a part length thereof. The ridges (7) are arranged to engage with and move past corresponding ridges of an adjacent panel (6) when the panels move relative to each other in opposite directions. The ridges (7) are further arranged so as to interfere with the ridges of the adjacent panel to resist relative movement in a reverse of the opposite direction.

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.

A stay-in-place form comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.
