  • Publication number: 20230104236
    Abstract: Methods are provided for repairing an existing structure to cover at least a portion of the existing structure with a repair structure. Such methods comprise mounting one or more standoff retainers to the existing structure; coupling one or more standoffs to the standoff retainers such that the standoffs extend away from the existing structure; coupling one or more cladding panels to the standoffs such that the panels are spaced apart from the structure to provide a space therebetween; and introducing a curable material to the space between the panels and the existing structure, the panels acting as at least a portion of a formwork for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the panels. Corresponding apparatus for effecting such methods are also provided.

  • Patent number: 11499308
    Abstract: A structure-lining apparatus for lining one or more surfaces of a structure formed from curable material cast in a form. The apparatus comprises a plurality of panels. The panels are connected at their respective edges in an edge-to-edge connection to provide a structure-lining surface. A plurality of anchoring components project from the panels into the liquid material during fabrication of the structure. The anchoring components each comprise one or more anchoring features which are encased in the material as the material solidifies to thereby bond the anchoring components to the structure. The plurality of anchoring components comprises one or more connector-type anchoring components for connecting to corresponding connector-type anchoring components on adjacent edges of a corresponding edge-adjacent panel to connect the edge-adjacent panels in an edge-adjacent relationship. The apparatus comprises one or more breakaway components on at least one of the plurality of panels.

  • Patent number: 10151119
    Abstract: A tool is used for assembling at least a portion of a stay-in-place form-work for casting a structure from concrete, the form-work comprising first and second elongate panels having first and second edge components and connectable in an edge-to-edge relationship wherein the first and second edge components engage one another. The tool comprises: a first arm having a first handle, the first arm terminating at a first tool head; and a second arm having a second handle, the second arm terminating at a second tool head and pivotally attached to the first arm by a pivot joint. The first tool head comprises a first protrusion for engaging the first edge component. The second tool head comprises a second protrusion for engaging the second edge component; the first and second handles are moveable toward one another in a manner which forces the first and second tool heads toward one another thereby forcing the first and second edge components into a locked configuration.

  • Patent number: 10022825
    Abstract: Methods and apparatus are provided for repairing existing structures. A portion of the existing structure is covered with the repair structure. One or more standoffs are coupled to the existing structure to project outwardly away from a surface of the existing structure. One or more cladding panels are coupled to the standoffs by forcing the one or more panels in a direction normal to the surface of the existing structure and into engagement with a standoff connector component of the standoff at a location spaced apart from the existing structure. Curable construction material and/or insulation may be introduced into the space between the cladding panels and the existing structure to provide a repair structure.

  • Publication number: 20180112399
    Abstract: A stay-in-place lining is provided for lining a structure fabricated from concrete. The lining comprises a plurality of panels connectable via complementary connector components on their longitudinal edges. Each panel comprises a first connector component on a first longitudinal edge thereof and a second (complementary) connector component on a second longitudinal edge thereof. The lining comprises at least one edge-to-edge connection between the first connector component of a first panel and the second connector component of a second panel, the edge-to-edge connection comprising a protrusion of the first panel extended into a receptacle of the second panel through a receptacle opening. The receptacle is shaped to prevent removal of the protrusion from the receptacle and the receptacle is resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the edge-to-edge connection.

    Abstract: A cladding kit is provided for a structure cladding, the structure cladding comprising a first panel that extends away from a structure location along a first surface portion of the structure and a second panel that extends away from the structure location along a second surface portion of the structure. The cladding kit comprises a base piece couplable to the structure at the structure location, the base piece comprising a base connector, and a trim piece comprising first and second wings and a trim connector shaped to make a connection with the base connector to thereby couple the trim piece to the base piece. The first wing is shaped to contact, and be deformed by, the first panel when a connection is made. The second wing is shaped to contact, and be deformed by, the second panel when the connection is made.
