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.

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).

A method of manufacturing a decorative surface includes the steps of a) impregnating a paper substrate with a thermosetting resin; b) jetting a colour pattern with one or more aqueous inkjet inks including a polymer latex binder on the thermosetting resin impregnated paper; c) drying the one or more aqueous inkjet inks; and d) heat pressing the thermosetting paper carrying the colour pattern into a decorative surface.

The present invention belongs to the technical field of energy consumption and vibration reduction of assembled building structures, and provides an energy-consuming connecting device for a prefabricated assembled wall. The present invention provides a normal connection function between walls, and also has the functions of energy consumption and vibration reduction. A used viscoelastic material can provide energy consumption and weaken the cold and hot bridge effect, which is beneficial to building thermal insulation. Meanwhile, the energy-consuming connecting device for the prefabricated assembled wall can be connected with a prefabricated wall in advance, which can be carried out at the same time as the wall is inserted during construction, thereby effectively increasing the construction efficiency. Through the design of clamping groove devices, the wall can be connected firmly and reliably while generating displacement and consuming energy. A multi-segment fixing plate is used to replace full-length arrangement to save the steel.

An interface for a structural member includes at least one first sidewall that extends from a first end along a longitudinal direction and defines a first cavity. The at least one first sidewall defines a female end section and includes a transversely oriented female end surface at the first end. The interface also 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 defines a male end section adjacent the second end and configured to be received within the first cavity, and a stop surface offset longitudinally from the second end and oriented to bear against the female end surface in substantially face-to-face contact when the male end section is received within the female end section. The stop surface and the male end section are integrally formed and monolithic.

Various embodiments of interconnectable pieces are described that collectively form a surface. The pieces comprise one or more routed edges or cutouts that can be configured to receive an insert used to couple adjacent tiles to one another. Some inserts may comprise one or more magnets or magnetized portions to magnetically couple the pieces with adjacent pieces.

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 method is provided for manufacturing a panel that includes a substrate and a top layer provided on the substrate. The top layer may include a decor film and a transparent film. The decor film may be a printed synthetic material film chosen from the group consisting of a vinyl-based film, a polyethylene based film, a polyurethane based film, and a polypropylene film. A print may be situated on an upper side of the printed synthetic material film. The transparent film may be a thermoplastic synthetic material film the material of which is chosen from the group consisting of polyvinyl chloride, polyethylene, polyurethane, and polypropylene. The method may involve providing the decor film and the transparent film on the substrate by performing a first press treatment at an increased temperature to form a package of the substrate, the decor film, and the transparent film. The first press treatment may be performed by a calendar device or a continuous press device. A structure may be formed in the thermoplastic synthetic material that forms a surface of the package by performing a second press treatment using a press device with a structured press element at a temperature that is lower than the increased temperature.
