Abstract
Formwork for building a wall system, the formwork comprising: a first pre-cast concrete wall panel and a second pre-cast concrete wall panel, the first wall panel being adapted for being positioned in a spaced relationship with the second wall panel; a hollow core defined by oppositely arranged surfaces of the first and second wall panels, the core being adapted for receiving wet concrete; and a connecting arrangement for inter-connecting the first wall panel with the second wall panel in the spaced relationship, the connecting arrangement extending generally in an outwardly direction relative to said oppositely arranged surfaces of the first and second wall panels.
Claims22
Formwork for building a wall system, the formwork comprising:
- a first discrete reinforced pre-cast concrete wall panel and a second discrete reinforced pre-cast concrete wall panel, the first wall panel being adapted for being positioned in a spaced relationship with the second wall panel;
- a hollow core defined by oppositely arranged spaced apart surfaces of the first and second wall panels, the core being adapted for receiving wet concrete;
- and
- a connecting arrangement for inter-connecting the first wall panel with the second wall panel in a variable spaced relationship, the connecting arrangement extending generally in an outwardly direction relative to said oppositely arranged spaced apart surfaces of the first and second wall panels and being positioned along respective lengths of the first and second wall panels in between opposite lateral ends of the first and second wall panels and
- wherein lateral edge portions of the first and second panel comprise reinforcing members extending horizontally from each of said edge portion for inter-connecting a first pair of said first and second panels with a second pair of said first and second panels along their respective lateral edge portions.
Formwork in accordance with any one of the preceding claims further comprising a spacer for being positioned and retained in between respective summit portions of the first and second panel during use.
Formwork in accordance with any one of the preceding claims wherein the formwork further comprises one or more additional reinforcing members extending through the core, the reinforcing members extending in an outwardly direction, preferably in a vertical direction relative to a supporting surface supporting the first and second wall panel.
Formwork in accordance with any one of the preceding claims further comprising a lintel member for being positioned above in-use upper portions of the first and second panels, the lintel member further comprising connecting members for connecting the lintel member to the core of the formwork.
Formwork in accordance with any one of the preceding claims further comprising a scaffold securing arrangement for removably securing scaffolding to at least one of said pre-cast panels.
Formwork in accordance with any one of the preceding claims further comprising a plurality of spaced apart elongate reinforcement members positioned in the hollow core in between lateral ends of said first and second wall panels and extending generally in a vertical direction relative to a supporting surface underlying said wall system.
A discrete pre-cast reinforced concrete panel to construct formwork for a wall system in a building, the panel comprising a plurality of summit portions spaced apart from each other by furrow portions wherein two of said panels can be oppositely arranged to position the summit portions of each panel in a connected configuration, wherein one or more of the summit portions comprises a connecting arrangement for inter-connecting one of said concrete panel with another of said wall panel in a variable spaced relationship, the connecting arrangement extending generally in an outwardly direction relative to an inwardly directed in-use surface of the panel and positioned in between opposite lateral ends of the panel and wherein the furrow portions of the oppositely arranged panels define a plurality of hollow cores for receiving fresh concrete therein.
