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).

Systems and methods for creating insulated sandwich walls with a prefabricated framework are provided. An inner strongback faces an outer strongback. Outer and inner support members are located between the strongbacks. The strongbacks and support members extend vertically from a base. Material for an outer wall, such as concrete, is deposited between the outer strongback and outer support member. Material for an inner wall is deposited between the inner strongback and inner support member. An insulating material is deposited between the outer and inner support members providing longitudinal spacing for the framework.

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.

The invention relates to a permanent concrete formwork for manufacturing a metal-concrete composite structure, comprising: two walls each comprising at least one metal plate, the walls being parallel, arranged opposite one another, and spaced apart from one another so as to define an inner space of the formwork; struts which connect the two walls and which attach the two walls to one another, the struts passing through the two walls and projecting from either side of the formwork; bars located on each of the walls and which project into the inner space of the formwork, wherein each metal plate is attached to the opposite metal plate by at least three struts, the first strut being located at a first end of the metal plate, the second strut being located at a second end opposite said first end, and the third strut being located in a central region located between the first end and the second end, and in that the struts comprise threaded ends, the struts being attached to the metal plate by bolting.

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.

Disclosed is an economical and effective way of producing a double sided wall using facing panels having a face surface and a back surface with a retaining structure. The facing panels are stacked in a back-to-back arrangement into a pair of first and second wall components connected by separate articulated connectors. The articulated connectors each have a first base connector that fits into a respective retaining groove in the first wall component and a second base connector that fits into a respective retaining groove of the second wall component. The first and second base connectors are connected to each other by a link that forms a first pivot joint at the first base connector and a second pivot joint at the second base connector.

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.

A kit for constructing a stackable column, the kit including at least four pre-fabricated interlocking members. Each interlocking member also includes a lower segment wall and an upper segment wall. The lower segment wall extends in a first direction as well as a second direction perpendicular to the first direction. The upper and lower segments each have at least three edges with locking features for engagement with an adjacent interlocking member. The plurality of interlocking members surround and are secured to a post with a brick tie. The interlocking members include features on the at least three edges for locking engagement with an adjacent interlocking member.

Disclosed herein is a system 100 for constructing an insulated thermal mass concrete structure comprising four or more walls 100a, 100b, 100c, 100d. The system 100 comprises interconnected frame members 30, 30, 30, 30, 30*, cross-ties 40 and corner members 33, 33, which reduces the need for props or stays to support the walls 100a, 100b, 100c, 100d during curing of a concrete core poured between inner and outer layers, 20, 21, 22, 23, 25 attached to the frame members 30, 30, 30, 30, 30*.
