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.

Systems and methods for creating insulated sandwich walls with a prefabricated framework are provided. An inner strongback faces an outer strongback. Outer and inner support members are located between the strongbacks. The strongbacks and support members extend vertically from a base. Material for an outer wall, such as concrete, is deposited between the outer strongback and outer support member. Material for an inner wall is deposited between the inner strongback and inner support member. An insulating material is deposited between the outer and inner support members providing longitudinal spacing for the framework.

An insulating concrete form system for the construction of insulated concrete walls, floors or roofs, the system comprising: at least one first panel; at least one second panel configured to be placed opposite to the at least one first panel, and a plurality of spacers configured to interconnect the at least one first panel and the at least one second panel while defining a space between the at least one first panel and the at least one second panel. A method for constructing a concrete wall, floor or roof, as well as additional embodiments of the system and method, are provided herein.

There is provided herein a modular be fabricated wall system which has a number of interlocking modular prefabricated wall sections. Each wall section has opposing planar face boards and a number of orthogonal spacers adhered to respective inner faces of the face boards for bracing the face boards apart. Vertical joiners may be adhered to inner edges of each face board for quickly and easily vertically slotting together adjacent wall sections in a row. The present wall sections are low-cost in that both the face boards and the orthogonal spacers may be cut from low-cost board, such as fibre cement board. Specifically, the face boards and the spacers may be both made from fibre cement board and the spacers may be glued perpendicularly between inner surfaces of the face boards. As such, the present wall sections may be manufactured without fasteners, ties and the like.

A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other, where the first sidewall has a first passage extending therethrough, with a first insert received in the first passage of the first sidewall. The form also includes a first cross tie having opposed first and second ends, where the first sidewall is removably secured to the first end of the first cross tie and the second sidewall is secured to the second end of the first cross tie. A first fastener extends through the first passage and engages the first insert and the first end of the first cross tie to removably secure the first sidewall to the first cross tie. The second sidewall may be removably or non-removably secured to the first cross tie.

A form system for an in-ground swimming pool may include inner and outer form panels to be coupled in side-by-side relation. Support members may be for coupling the outer form panels in spaced relation from the inner form panels to define a wall space therebetween. Each of the support members may include a base member to be carried by respective inner and outer form panels over the wall space, an arm extending from the base member for coupling to the respective outer form panel, and a wall support member for coupling to the respective inner form panel. The wall support member may include a wall support lip extending from a wall support body for engaging the respective inner form panel so that the respective inner form panel is suspended from the wall support lip.

A barrier forming system is described that includes a plurality of studs, rails and barrier reinforcement members interconnected between top and bottom plates. The interconnected studs, rails, reinforcement members, top plate and bottom plate may be precisely bent or curved in either or both the vertical and horizontal directions. The interconnected studs, rails, barrier reinforcement members, top plate, and bottom plate may be embedded in a filler material to form a curved concrete barrier having a complex geometry.

The invention relates to a permanent concrete formwork for manufacturing a metal-concrete composite structure, comprising: two walls each comprising at least one metal plate, the walls being parallel, arranged opposite one another, and spaced apart from one another so as to define an inner space of the formwork; struts which connect the two walls and which attach the two walls to one another, the struts passing through the two walls and projecting from either side of the formwork; bars located on each of the walls and which project into the inner space of the formwork, wherein each metal plate is attached to the opposite metal plate by at least three struts, the first strut being located at a first end of the metal plate, the second strut being located at a second end opposite said first end, and the third strut being located in a central region located between the first end and the second end, and in that the struts comprise threaded ends, the struts being attached to the metal plate by bolting.

The instant invention provides a secure holding spacer unit to be used when assembling permanent stay-in-place formworks, also known as permanent stay-in-place molds, which are commonly used for the construction of concrete structures by putting together two boards or panels held together by a series of holding spacer units that are securely attached or hold to the surfaces of the cement panels by fastening means that pass through the width of the panels. The holding spacer units are selectively distributed within the internal cavity of the formwork and are attached to the panels, and are designed so that the panels remain permanently attached to the units of the spacers, to restrict the outward movement of said panels when pouring the concrete mix in the unit, which results in a permanent formwork with smooth exterior surfaces.
