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.
Claims15
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;
- a first pretensionable member or members, and/or resiliently deformable 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;
- a second pretensionable member or members, and/or resiliently deformable member or members, attachable between at least one said tetherable ends of the second lengths of chain and a second link member or members;
- and
- wherein the link member or members being attachable to or extendable through the formwork or mould, wherein, in use, the reinforcement assembly being adjustable to pretension the first and second lengths of chain prior to a concrete mixture being poured into the formwork or mould, whereby the pretensioned reinforcement assembly being embedded within the resultant concrete structure.
A reinforced concrete structure comprising a reinforcement assembly embedded therein, the reinforcement assembly including first and second lengths of chain, a plurality of pretensionable members and/or resiliently deformable members, and a plurality of mounting blocks, wherein, in use, the pretensionable members and/or resiliently deformable members are positionable intermediate of the first length of chain or the second length of chain and one of the plurality of mounting blocks, whereby the first and second lengths of chain being pretensionable prior to forming of the concrete structure.
A method of reinforcing a concrete structure including the steps of:
- constructing a temporary formwork, or providing a mould, which delineates a boundary of a desired concrete structure;
- positioning a reinforcement assembly inwardly of the formwork or mould, the reinforcement assembly comprising lengths of chain, mounting blocks, pretensionable members and/or resiliently deformable members, and link members which are attachable to the mounting block and configured, in use, to extend through or over the formwork or mould, wherein the pretensionable members and/or resiliently deformable members are positionable intermediate of at least one end of some of the lengths of chain and a corresponding mounting block;
- adjusting the link members and/or pretensionable members to thereby tension the lengths of chain;
- pouring a concrete mixture into the formwork or mould to form the concrete structure;
- allowing the concrete mixture to cure;
- and
- removing the framework, or removing the concrete structure from within the mould, wherein the lengths of chain are maintained in a pretensioned condition within the concrete structure.
