Abstract
There is proposed a reinforced concrete structure comprising a reinforcement assembly embedded therein, the reinforcement assembly including first and second lengths of chain, wherein the first and second lengths of chain being pretensionable prior to forming the concrete structure. The reinforcement assembly includes pretensionable member/s and/or resiliently deformable member/s intermediate of at least one tetherable end of the lengths of chain and a mounting block or link member.
Claims18
A reinforcement assembly for a concrete structure being formed using a formwork or mould, comprising:
- a plurality of spaced apart first lengths of chain having opposite tetherable ends, the first lengths of chain each including a plurality of interlocked chain links configured for passage of a flowable concrete mixture therethrough;
- a first pretensionable member or members, attachable between at least one of said tetherable ends of the first lengths of chain and a first link member or members;
- a plurality of spaced apart second lengths of chain having opposite tetherable ends, the plurality of second lengths of chain at an angle to the first lengths of chain, the second lengths of chain each including a plurality of interlocked chain links configured for passage of a flowable concrete mixture therethrough;
- a second pretensionable member or members attachable between at least one of said tetherable ends of the second lengths of chain and a second link member or members;
- and
- wherein the first link member or members and/or the second link member or members being attachable to or extendable through the formwork or mould, wherein, in use, the reinforcement assembly being adjustable to tension the first pretensionable member or members and the second pretensionable member or members to thereby hold the first lengths of chain and the second lengths of chain in a tensioned condition prior to a flowable concrete mixture being poured into the formwork or mould, whereby the first pretensionable member or members and the second pretensionable member or members being embedded within the concrete structure and the flowable concrete mixture extending through each of the plurality of interlocked chain links of the first lengths of chain and second lengths of chain, whereby the first lengths of chain and the second lengths of chain are maintained in the pretensioned condition within the cured concrete structure.

A method of reinforcing a concrete structure comprising:
- constructing a temporary formwork or mould which delineates a boundary of a desired concrete structure;
- positioning a reinforcement assembly inwardly of the temporary formwork or mould by:
- providing a plurality of lengths of chain with tetherable ends, the plurality of lengths of chain comprise interlocking chain links;
- providing a pretensionable member or members;
- providing a link member or members;
- spacing the plurality of lengths of chain apart from one another in the formwork or mould;
- attaching the pretensionable member or members between at least one of said tetherable ends of one or more of the plurality of lengths of chain and the link member or members;
- attaching or extending the link member or members to or through the formwork or mould;
- adjusting the link member or members and/or the pretensionable member or members to tension the plurality of lengths of chain;
- retaining the plurality of lengths of chain in a tensioned condition;
- pouring a flowable concrete mixture into the formwork or mould;
- extending a quantity of the flowable concrete mixture through the chain links of each of the plurality of lengths of chain while in the tensioned condition;
- embedding the pretensionable member or members within the flowable concrete mixture;
- maintaining the plurality of the lengths of chain in the tensioned condition;
- curing the flowable concrete mixture into a solid concrete mixture to form the desired concrete structure;
- and
- removing the temporary formwork or mould, or removing the desired concrete structure from within the temporary formwork or mould, wherein the plurality of lengths of chain are maintained in the tensioned condition within the desired concrete structure.
