<p>Abstract A formwork system for use in constructing a core filled wall in situ, the system including: two rigid panels configured to define the two opposing planar surfaces of a wall, and a plurality of flexible tensile tie elements captively retained with, and extending between, the two rigid panels to define the maximum spacing achievable between the panels at each location. In one form which is collapsible for transportation, the system includes two rigid longitudinally extending end elements which define the longitudinal edge boundaries of the formwork, with all the ties between the panels between the end elements being in the form of the flexible tensile ties. In another form, well suited for use in load bearing walls where bulky internal reinforcement configurations may be a specified pre-requisite, the system includes a plurality of vertically extending spaced rigid web elements secured with and extending between the opposing panels to define a series of vertical voids interconnected via spaced openings provided in the a plurality of rigid web elements, with one or more rigid webs being replaced with a vertically extending plurality of flexible tensile tie elements as described above. This enables increased void space to accept bulky reinforcement, while at the same time potentially reducing weight and cost. 7ir [--- 12 Fig 6 10 8-- || Fig|7</p> |
