A structure-lining apparatus comprising a plurality of transversely and longitudinally extending panels connectable to a structure and connectable edge-to-edge via complementary connector components on their longitudinally extending edges. Each panel comprises transversely extending edges generally orthogonal to their longitudinally extending edges. Each panel comprises first and second complementary connector components on first and second longitudinally extending edges thereof. The apparatus comprises at least one edge-to-edge connection between a first connector component of a first panel and a second connector component of a second panel wherein a primary male connector component of the second connector component of the second panel is extended into a primary female connector component of the first connector component of the first panel and a secondary male connector component of the first connector component of the first panel is extended into a secondary female connector component of the second connector component of the second panel.

Longspan stay-in-place liners

A method covers at least a portion of a surface of an existing structure with a repair structure. The method comprises: providing a standoff, the standoff elongated in a longitudinal direction and operable from an open configuration to a closed configuration; while the standoff is in the open configuration, mounting the standoff to the existing structure, such that the standoff projects outwardly away from the surface of the existing structure; closing the standoff to the closed configuration, the closing of the standoff forming a standoff connector; and coupling a cladding panel to the standoff by engaging the panel with the standoff connector at a location spaced outwardly apart from the surface of the existing structure by a void.

Snap-together standoffs for restoring, repairing, reinforcing, protecting, insulating and/or cladding structures

A method for repairing a multi-sided structure protruding from a first surface. The method comprises mounting a retainer to the first surface, coupling a first brace connector component of a first brace to a first panel, coupling the first panel to a primary retainer connector component of the retainer, coupling a second brace connector component of the first brace to a secondary retainer connector component of the retainer, and introducing a curable material into the space between the first panel and the multi-sided structure, the first panel acting as at least a portion of a framework for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the first panel.

Retainers for restoring, repairing, reinforcing, protecting, insulating and/or cladding structures

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.

Methods and apparatus for restoring, repairing, reinforcing and/or protecting structures using concrete

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.

Structure-lining apparatus with adjustable width and tool for same

A stay-in-place form comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprises first and second panels connectable to one another in edge-adjacent relationship by a connection which comprises a contact joint. The first panel comprise a longitudinally extending first seal-retaining projection shaped to project outwardly from the outer surface of the first panel at a location spaced apart from a first outer-surface transverse edge of the first panel in a first transverse direction. The second panel comprising a longitudinally extending second seal-retaining projection shaped to project outwardly from the outer surface of the second panel at a location spaced apart from a second outer-surface transverse edge of the second panel in a second transverse direction opposite the first transverse direction. The first and second seal-retaining projections and the outer surfaces of the first and second panels defining at least a portion of a seal-receiving concavity which opens outwardly from the form when the connection is made.

Liquid and gas-impermeable connections for panels of stay-in-place form-work systems

An apparatus for a stay-in-place form assembly comprises a plurality of elongated panels connectable to one another in edge-to-edge relationship. The plurality of panels comprise first and second panels connectable to one another at a connection between a generally male connector component of the first panel and a generally female connector component of the second panel. The generally female connector component comprises a female engagement portion which defines a principal receptacle and the generally male connector component comprises a male engagement portion which is received in the principal receptacle to form the connection. The generally female connector component comprises a first abutment portion and the generally male connector component comprises a second abutment portion which abuts against the first abutment portion to form the connection. The first and second abutment portions are located outside of the principal receptacle.

Connector components for form-work systems and methods for use of same

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.

Tool for making panel-to-panel connections for stay-in-place liners used to repair structures and methods for using same

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.
