Abstract
The present invention relates to a system and method for constructing a pre-stressed modular construction for supporting or retaining an applied load. In particular, the present invention relates to a system and method for pre-stressed modular retaining walls. The system comprises a plurality of header stacks constructed from a variety of header units. The header stacks are coupled by structural members. Active reinforcement elements are used to induce a pre-stressing force into the header stacks to support or retain the applied load. A method for constructing the modular construction is provided.
Claims73
A system for constructing a pre-stressed modular construction for retaining or supporting an applied load, comprising:
- a header stack, wherein said header stack is comprised of a plurality of header units wherein said header units are stacked one on top of another to thereby provide contact between adjacent header units in said header stack;
- and
- an active reinforcement element configured to cooperate with said header stack so that post-tensioning said active reinforcement element imparts a corresponding pre-stressing force into said header stack.
54 The system of claim 53, wherein said junction element is integrally formed with said body element.
The system of claim 54, wherein said junction element extends from said body element in an angular configuration.
A pre-stressed modular construction for retaining or supporting an applied load, comprising:
- at least two header stacks, wherein each of said header stacks is comprised of a plurality of stacked header units wherein said stacked header units are stacked one on top of another to thereby provide contact between adjacent stacked header units in each of said header stacks;
- at least one pre-stressing tendon for each of said header stacks, wherein each pre-stressing tendon is configured to cooperate with its header stack so that post-tensioning said pre-stressing tendon prior to application of the applied load imparts a corresponding pre-stressing force into its header stack at at least one lock-off point;
- and
- a structural member coupled to said at least two header stacks.
