A flooring substrate system that uses one of three substrate components upon which various types of finish flooring may be attached above a deck structure. The deck structure may be open lumber framed or may be a waterproofed planar surface. Affixation of the flooring system may be by direct connection or by gravitational placement. Height and slope adjustable components interlock through a plunge, twist and locking teeth arrangement to form supporting members beneath the substrate components. A base mounting plate acts as a pivotal point in the system, having recesses and engageable configurations on both its faces for other system components.

A tile levelling device (10) includes a base portion (12) having an upper surface (14) and an opposing lower surface (16), the lower surface (16) being substantially planar; two stems (20) each having a proximal end frangibly connected to the base portion (120) and a distal end connected to a body (32), a generally rectangular hole (34) being defined by the stems (20) the base portion upper surface (14) and the body (32), the hole (34) being adapted to receive a wedge (50); and a stiffening formation (70) located at or near the interface between each stem (20) and the body (32).

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

A set comprising a connection foot and a soil covering element support element, which support element comprises a basis provided for being applied on a surface raising pedestal, which basis comprises a stop member, which connection foot is provided for connecting the support element to the pedestal, which basis of the support element comprises a set of attachment slats, which connection foot comprises a set of first attachment members, the first attachment members being applied in such a manner as to be able to engage between the attachment slats and enter into contact with them so as to enable a translatory movement between the support element and the connection foot, which connection foot comprises a second set of attachment members provided for gripping with the pedestal and enabling a rotation of the connection foot with respect to the pedestal.

A wedge device for leveling tiles and a clip set for use of the same are disclosed. In one embodiment of the wedge device, the wedge device includes a body having an attachment end, a penetrating edge, a top, and a bottom. The attachment end is coupled to a backstop member and the penetrating edge is configured to penetrate the clip member. The body includes an inclined plane tapering from the attachment end to the penetrating edge. A line-of-sight opening extends along a longitudinal axis of the body to provide visibility through the body from the top to the bottom.

A tile spacer and wedge tool for installation of tile work. The tool includes a center surface from which one or more of a cross element and a bar element protrude form the center surface. The elements have a width corresponding to a desired spacing between adjoining tiles. An integrally formed wedge extends radially outwardly from a side of the spacer and wedge tool and is substantially aligned with the center surface. The combined tile spacer and wedge tool provides a single spacing tool that may be used for any aspect of a tile work installation, allowing the installer to carry only a single tool. The tile spacer and wedge tool have a more robust construction than conventional spacers, allowing them to be reused for installation work for an indefinite number of uses.

A flooring substrate system that uses one of three substrate components upon which various types of finish flooring may be attached above a deck structure. The deck structure may be open lumber framed or may be a waterproofed planar surface. Affixation of the flooring system may be by direct connection or by gravitational placement. Height and slope adjustable components interlock through a plunge, twist and locking teeth arrangement to form supporting members beneath the substrate components. A special fastening system is utilized between two of the substrate components to compensate for high wind lift load conditions.

A tile aligning and lippage tuning system that uses a single piece base and strap which is designed to break away from the base when sufficient pressure is applied and is also designed to stretch along a thin wall region before separation of the strap from the base occurs.

Provided is a levelling spacer device for laying slab products for cladding laying surfaces. In some embodiments, the levelling spacer device includes a support having a base and a separator element provided with a through-window with two upper tilted sub-edges and a lower edge; and a presser wedge to be inserted in the through-window and to slide restingly on the in-view surface of the slab products, with an upper face having two adjacent areas running longitudinally along the length of the pressing wedge, and that are tilted downwards towards each other along a common convergent axis, and that cooperate, each, with a respective one of the two upper tilted sub-edges to push the slab products downwards. Also provided is a computer program product for manufacturing the presently disclosed device by 3D printing.

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more resilient compression elements joined with the spacer block. The resilient compression elements can be vertically compressible so at least a portion of it can move from an open mode to a compression mode and fit within, then forcibly expand within, the groove, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. Related methods of use also are provided.
