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.

Described embodiments include a method, including arranging one or more frames (22) and one or more boards (24), such that the frames, together with the boards, enclose a space (26). The method further includes pouring first concrete (28) into the space, and, after the first concrete solidifies, within the space, into a structure (42), removing the boards from the structure. The method further includes pouring second concrete (70) over the frames, such that the second concrete solidifies, over the frames, into respective walls that are adjacent to the structure. Other embodiments are also described.

A wall assembly for forming an external wall on a building structure is disclosed. The wall assembly comprises a cladding and a plurality of vertical formwork members spaced along the wall assembly, and a horizontal formwork member extending along the top of the wall assembly. The formwork members are elongate profiles having a substantially constant cross sectional shape and they are arranged so that with the cladding they form an interconnected formwork defining a formwork space. A cementitious material cast within the formwork space is interconnected and forms a single underlying structural frame within the constructed wall assembly. The assembly includes connectors extending between the vertical and horizontal formwork members and the cladding on which they are mounted. Each connector extends from the cladding through the formwork space to the formwork member and is cast within the cementitious material. A method of building a wall assembly is also disclosed.

The insulating concrete form system includes longitudinal and corner block assemblies each having a pair of side panels configured with tie receivers interacting with panel spacing ties to hold the side panels in an opposing manner and leading edges with an alternating arrangement of projections and recesses for interlocking with neighboring block assemblies. Each panel spacing tie includes a mid-support section interposing in between and connecting to a pair of end sections by a living hinge with each end section being configured with a flange member for placement within an opposing spatial wedge of the tie receiver, whereby the living hinge possesses the capability of allowing the side panels to move inwardly toward one another in a racked position to yield compactness of the longitudinal block assembly for economical transport. The corner block assembly also includes corner panel spacing ties to supplementally reinforce its structure to withstand hydrostatic blowout caused by poured concrete.

The invention relates to a sheet (10) for protecting a form-work surface, intended to surround a construction material. According to the invention, the sheet (10) comprises at least: a front layer, including at least one polymer material and provided to be in contact with the construction material so as to reduce wear and the formation of grooves on the framework surface and to limit adhesion of the construction material during removal of the formwork; and a rear adhesive layer, provided to be positioned against the formwork surface and rigidly connect the sheet (10) to the formwork surface before the construction material is introduced. The invention also relates to a formwork installation (1) equipped with at least one such sheet (10). The invention further relates to a method of producing and a method of using a sheet (10) of this type.

The invention comprises connector for a pair of opposed spaced concrete forming panels. The connector comprises an elongate spacer member having flanges formed thereon intermediate a central portion thereof and each opposite end thereof. A portion of at least one end of the spacer member is sized and shaped to selectively engage an elongate panel bracing member. A composite insulated concrete form and a method of using the insulated concrete form are also disclosed.

A waler bracket for use with a concrete wall form includes a main frame portion connecting arm attached to a framing wall stud projecting from the wall form, a spring including a first and second end, a handle attached the connecting arm and to a cam-lock. The handle moves between non clamping and clamping configurations thereof, and rotates the cam-lock, which in turn engages the spring such that the first and second ends act in torsion, such that the first end engages the second end in compression, which in turn causes an abutment against a waler.

A shuttering formwork suitable for use as sacrificial shuttering formwork includes an elongate body member having a base portion and a compression portion extending therefrom and presenting a free end that extends in a length direction of the elongate body member. The elongate body member has first and second sides, each comprising a compression portion side face and a base portion upper face. A strip element is releasably attachable to the free end of the compression portion. The compression portion side face and the base portion upper face of at least one side of the elongate body member are each a resiliently deformable surface. The base portion is provided with apertures for receiving mortar material. The shuttering formwork may be fabricated from a plastics material and have a hollow structure.
摘要:
A device and method for pouring consecutive concrete sections. The inventive device and method preferably include a barrier used to separate adjacent concrete slabs. This barrier is preferably erected in such a way that it allows a construction crew to continuously pour concrete in successive sections of a concrete structure, which prior to the current invention, could not be poured continuously. Previously, concrete sections were poured in an alternating fashion in order to create an expansion joint between each section of concrete which also acts to break the bond between each concrete section. However, the current inventive method and device allows the crew to pour adjacent concrete sections while still creating a joint between each concrete section. Each concrete section barrier preferably includes an upright surface and dowel sleeves. Prior to pouring concrete into each designated gap dowel bars are inserted into each dowel sleeve.
