Module for a structure
A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.
1. A module for a structure comprising:
a formwork tray comprising a base and a pair of side walls that extend upwardly therefrom, the base and sidewalls together defining a cavity for reinforcement and concrete, the cavity including an upper section and a lower section; and
a reinforcement member located in the cavity and comprising an upper portion and a lower portion, the upper portion extending across a width and along a length of the upper section of the cavity, and the lower portion extending at least substantially along a length of the lower section of the cavity;
wherein a section of the base projects upwardly from adjacent sections thereof to define a land portion within the cavity that separates the lower section of the cavity into at least two spaced-apart elongate troughs; and
wherein when concrete fills the cavity and at least partially covers the reinforcement member, the lower portion of the reinforcement member and the concrete together define at least one elongate beam, the land portion defining a volume of the formwork tray that does not receive concrete.
2. The module for a structure of claim 1 , wherein the formwork tray comprises across a width thereof a plurality of interconnected discrete formwork sections.
3. The module for a structure of claim 2 , wherein the plurality of discrete formwork sections include at least two U-shaped sections interconnected by a stiffening member.
4. The module for a structure of claim 1 , wherein each of the elongate troughs span along an entire length of the module, such that the lower portion of the reinforcement member and the concrete together define at least two elongate beams.
5. The module for a structure of claim 1 , wherein the formwork tray further comprises a pair of end walls forming with the side walls a perimeter about the base.
6. The module for a structure of claim 1 , wherein the formwork tray provides a plurality of channels and the reinforcement member has a plurality of attachment members to engage with the plurality of channels to engage the formwork tray with the reinforcement member independently of the concrete introduced into the cavity.
7. The module for a structure of claim 1 , wherein the lower portion of the reinforcement member and the upper portion of the reinforcement member are integrally formed.
8. The module for a structure of claim 1 , wherein the reinforcement member is configured to conform to the cavity.
9. The module for a structure of claim 1 , wherein the upper portion of the reinforcement member comprises a plurality of layers of mesh.
10. The module for a structure of claim 1 , wherein the lower portion of the reinforcement member further includes an end portion, such that concrete fills the cavity, the lower portion of the reinforcement member and the concrete together define a cross-beam oriented perpendicularly of the or each of the elongate beams.
11. The module for a structure of claim 1 , wherein the lower portion of the reinforcement member comprises a plurality of trusses.
12. The module for a structure of claim 11 , wherein each truss includes a pair of parallel line wires being interconnected by a cross-wire, the cross-wire extending diagonally back and forth between the pair of parallel line wires.
13. The module for a structure of claim 11 , wherein each truss further comprises a brace member.
14. The module for a structure of claim 13 , wherein each brace member is retained in engagement with each truss by tension.
15. The module for a structure of claim 1 , wherein the concrete at least partially fills the upper section of the cavity to cover the upper portion of the reinforcement member, such that the reinforcement member and the concrete together define an integrated, reinforced structure.
16. A reinforced concrete bridge comprising a module according to claim 1 , wherein the module spans at least partially across a width of the bridge and extends at least partially along a length of the bridge.
