A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

An interface for a structural column includes a female end section that includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. An interior surface of the at least one first sidewall tapers transversely outwardly along the female end section towards the first end. The interface also includes a male end section that includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall is configured to be received within, and oriented in substantially face-to-face adjacent relationship with, the at least one first sidewall. Each of the female end section and the male end section is a respective unitary casting.

A multi-panel kit defining one or more recesses for a structural joint. The kit including first and second panels for respectively defining first and second faces of the one or more recesses in use. One or more intermediate panels, each defining an intermediate face of at least one, of the one or more recesses in use, and one or more pairs of slots, each comprising a first slot through the first panel and a second slot through the second panel. The one or more recesses are intermediate the first and second panels, and the intermediate faces of each recess extending between the first and second faces of that recess. Each pair of slots is for receiving one of the one or more intermediate panels in use, and each of the one or more intermediate panels includes a first notch and a second notch for receiving an edge of the first slot and an edge of the second slot of a pair of slots respectively in use.

A system of structural interlocking panels for forming disaster-resistant buildings, comprising: a hollow, internally-braced, vacuum-insulated panel shell having at least two interlocking sides, the first side having a convex-inward single-curvature, the second side having a straight surface, the third side having a straight surface with at least one integral tongue with at least one head extending vertically-upward for receiving a complementary groove of a first side of an adjacent panel. Panels are thus vertically slide-locked along panel sides and faces, thereby triggering automatic snap joints that prevent backward movement of the panel. The system can assemble spheres, cylinders, toroids, tetrahedrons, flat shapes, and irregular shapes.

Various embodiments of flooring and other tiles are described that comprise one or more magnets and/or routed edges to connect adjacent tiles to one another. Some tiles may comprise a set of magnets or magnetized portions to connect with an adjacent tile having a set of magnets of opposite polarity.

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.

An interface for a structural column includes a female end section that includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. An interior surface of the at least one first sidewall tapers transversely outwardly along the female end section towards the first end. The interface also includes a male end section that includes at least one second sidewall that extends from a second end along the longitudinal direction and defines a second cavity. The at least one second sidewall is configured to be received within, and oriented in substantially face-to-face adjacent relationship with, the at least one first sidewall. Each of the female end section and the male end section is a respective unitary casting.

A composite material may be used as a building material to provide desirable visible aesthetics, such as in a roof or facade. The composite material may include two or more materials, wherein a first material provides desirable qualities for appearance and a second material provides desirable qualities for strength or other characteristics desirable of a building material. Each of the first material and the second material may be transparent, such that the composite material is also transparent. The first material may be Ethylene tetrafluoroethylene (ETFE) and the second material may be Polyethylene terephthalate (PET).
