A method for erecting a concrete structure by successively casting at least a first casting segment with a first floor slab, a second casting segment with a second floor slab and a third casting segment with a third floor slab includes providing a support column carrying a frame for suspending a formwork therefrom, the support column having a jack for transferring the support column from a retracted position to an extended position and vice versa, supporting the support column, by means of a first support bracket, arranging a second support bracket, at a vertical position between the second and third floor slab, on the support column, activating the jack for transferring the support column from the retracted position to the extended position, supporting the support column, by means of the second support bracket, and activating the jack for transferring the support column from the extended position to the retracted position.

A method of tensioning concrete is disclosed.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

A wall element comprises an inner surface, an outer surface, studs and at least one partial cavity and/or cavity. The studs are located between the inner surface and outer surface. The at least one partial cavity and/or cavity are also located between the inner surface and outer surface. The at least one partial cavity and/or cavity are designed to be filled with reinforced concrete The cavity and/or the partial cavity span from the top to the bottom and/or from side to side of the wall element.

A monolithic concrete modular connecting panel system for walls and roofs includes a foundation for a building, wall panels vertically aligned on the foundation and secured to the foundation to form a perimeter of the building. The system includes a plurality of roof panels secured to a top edge of the wall panels and spanning across the perimeter of the building. A plurality of crisscrossing rebar rods and wire mesh within the wall panels and roof panels are connected together with rebar rods of the foundation to form a steel cage for the building. Each wall and roof panel includes a metal frame, and a concrete board that divides the metal frames into an inner section and an outer section. In addition, the system includes concrete sprayed on the outer sections of the wall panels and sprayed or poured on the roof panels to form a monolithic concrete structure.

The invention comprises a 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 precast thermally separated cantilevered balcony system includes a concrete slab, a thermal separation component and a plurality of reinforcing bars. The concrete slab has an inside edge and a plurality of reinforcing bars extending therethrough generally orthogonal to the inside edge. The thermal separation component is an elongate member extending along the inside edge of the concrete slab. The plurality of reinforcing bars extend through the thermal separation component and extend inwardly from the thermal separation component. A method of constructing a building having at least one precast thermally separated cantilevered balcony system is discussed.

A composite wall, ceiling or floor panel (10), system and method, including a sheet (14) having a first face (18) including at least one first mounting portion (16), and at least one formwork member (20) with at least one second mounting portion (30) arranged to engage with the first mounting portion of the sheet to retain the sheet and said at least one formwork member together. Structural support comes from piers (for a wall) or beams (ceiling or floor) formed in the spacing between adjacent formwork members. The formwork members act as the core of a wall, ceiling or floor panel. An external coating (123) is applied to the formwork members, such as spray shotcrete or render. Channels (28) formed by the formwork members defines integrated ducting for services to be run.
