Interlocking modular tile frames for joining hard tiles without requiring a substrate adhesive (thin-set mortar) or grout. Each tile frame comprises integrated segments that form a rigid or semi-rigid enclosure to hold a single hard tile within its interior. Each segment has an upside-down T-shape cross-section comprising a column and a base. The columns, which frames a tile, eliminate the need for grout. An inserted tile rests on the base while being held in place by the column along each segment. One or more mechanical interconnections are located at an outer portion of each enclosure corner to couple adjacent frames together. A stain-resistant material such as but not limited to polyethylene, polycarbonate, polyvinyl chloride (PVC), polypropylene (PP), acrylic, ABS (acrylonitrile butadiene styrene), nylon, rubber, or a combination thereof, can be used for the frames.

One illustrative embodiment of a tile & support structure may be configured to secure the position of a tile in a generally vertical configuration, such as the riser of a step, as a border around a portion of a deck, a building and/or wall façade, ventilated façade, interior or exterior wall covering, or other generally vertical surface. The support structure may be formed with a spine having at least one rail extending outward from a distal end thereof. The spine and rail(s) may be configured to secure one or more tiles, which tiles may be formed with a groove on at least one edge thereof, and wherein one or more rails may be positioned within the groove.

Further described is a method of manufacturing the set of panels.

A floor frame includes at least two spaced longitudinal support strips and at least one lateral support strip. Each longitudinal support strip has longitudinal upper and lower portions and a pair of longitudinal side walls. A shoulder is designed on at least one of the pair longitudinal side walls and located between the longitudinal upper and lower portions. Two shoulders of the two longitudinal support strips are opposite to each other. The lateral support strip includes lateral upper and lower portions and a pair of lateral side walls. Two ends of the lateral support strip are placed on the two shoulders of the longitudinal support strips, respectively. A plurality of longitudinal and lateral support strips constitutes a grid-type structure under the distribution of longitudinal and lateral directions to provide the placement and fixation of a plurality of floor panels.

A double plate floor panel is provided. The double plate floor panel includes a first panel, a second panel, and a plurality of connectors. The first panel has a first plurality of recesses on a first surface, and the second panel has a second plurality of recesses on a second surface. Each connector of the plurality of connectors inserts into a recess of the first plurality of recess and a recess of the second plurality of recesses. The connectors are sandwiched between the first surface of the first panel and the second surface of the second panel. A method of assembling the double plate floor panel is also provided.

A structural element, including a base portion and a connecting central pin, has its base portion formed hallow, and having an internal reinforcement in the shape of WOW or MOM, to connect these elements with an insertable central pin so that the cross-section of the pin corresponds to the shape of the chamber between the reinforcements, when the upper surface of the structural element has longitudinal grooves, and is made from a modified polymer or elastomeric material comprising India rubber mixtures. The foundation is monomer ethylene propylene diene or natural rubber or styrene-butadiene rubber and/or combinations of the natural rubber/styrene-butadiene rubber, or thermoplastic elastomers, whose base is monomer ethylene-propylene-diene or polypropylene/monomer ethylene-propylene-diene or polyvinylchloride, or thermoplastic vulcanizates, whose base is monomer ethylene-propylene-diene and polyethylene or natural and/or synthetic rubber, modified by polyethylene or polypropylene.

A decking support system including a plurality of decking support elements, each decking support element including a first decking support engagement feature and a second decking support engagement feature, a plurality of connection elements, each connection element including a first connection feature adapted to co-operate with said first decking support engagement feature of a decking support element, and a second connection feature adapted to co-operate with said second decking support engagement feature of a decking support element, the arrangement being such that a first of said plurality of decking support elements is engageable with a second of said plurality of decking support elements by means of one of said plurality of connection elements dependent on said respective co-operations.

A connector system for mechanically connecting two structural elements to each other, consisting of a connector element and mating grooves in each structural element. The connector element is comprised of a base plate having a split-tongue element at each side or end of said base plate. Each joined element has a mating groove formed into its connector-receiving surface. The mating groove is designed to allow fabrication via four sequential circular saw cuts, without loss of saleable decorative surface, and at a rate consistent with economical commercial production of vinyl, laminate, or hardwood flooring. The connector element is readily extruded in a variety of polymers, including PVC. The connector and mating grooves interact so as to generate a force component acting to forcibly draw the connector into the mating grooves. The connector system operation is relatively insensitive to geometric deviations associated with normal manufacturing methods.

An aspect of the invention relates to a floor construction, comprising: o plural layers, the plural layers comprising at least one top layer and at least one subjacent layer underneath the at least one top layer, o and light sources arranged in one or more patterns in the at least one subjacent layer; o wherein the at least one top layer is translucent so as to hide the light source as well as the patterns when the light sources are off and to reveal the one or more patterns when the light sources are on.

A step clip fastening device, the step clip fastening device comprising: an elongated base strip having a first end and a second end, wherein a female locking part is attached to the first end and a male locking part is attached to the second end; a plurality of step clip sets extending substantially perpendicularly upwards from the base strip, wherein each of the step clip set comprising at least two step clips arranged in a back-to-back configuration, wherein a step clip is attached at each of the first end and the second end of the base strip; an anchor protruded at a center of each of the step clip; and one or more tabs extending substantially perpendicularly downwards from the base strip between two corresponding step clips facing each other.
