METHODS AND APPARATUS FOR PROVIDING LININGS ON CONCRETE STRUCTURES

摘要

Methods and apparatus are provided for lining one or more surfaces of con crete structures during fabrication thereof. A structure-lining apparatus co mprises a plurality of structure-lining panels and a plurality of concrete-a nchoring components. The panels, which may extend in longitudinal and transv erse directions, are interconnected to one another in edge-to-edge relations hip at their transverse edges to line at least a portion of the interior of the structural form. The concrete-anchoring components extend in an inward/o utward direction from the panels. The concrete-anchoring components may: be integrally formed with the panels; connect to the panels via suitably config ured connector components; and/or connect edge-adjacent panels to one anothe r. The concrete-anchoring components may comprise concrete-anchoring feature s which may extend in the longitudinal and transverse directions (e.g. in a plane parallel to the panels) to provide concrete-anchoring surfaces. In par ticular embodiments, the concrete-anchoring features comprise a stem which e xtends in the inward/outward and longitudinal directions and, at a distance spaced apart from the panels in the inward/outward direction, one or more le aves which extend in the longitudinal and transverse directions to provide a nchoring surfaces. Concrete is then poured intothe form on an interior of th e lining panels and allowed to solidify in the form. As the concrete solidif ies, the concrete-anchoring components bond the lining panels to the resulta nt concrete structure.
