Panels for floor coverings, wall coverings or ceilings have a first pair of opposite edges and a second pair of opposite edges. The opposite edges are provided with coupling parts that allow opposite edges of such panels to be coupled in a more easy way; and/or that allow that installation patterns can be made using the panels, without requiring a second type or second configuration of panels. The panel is provided with locking elements that create a locking of the so-coupled panels in the direction perpendicular to the plane of the panels; and in the direction parallel with the panels and perpendicular to the coupled panel edges.

A flooring module (100) for forming a temporary access floor comprises a base component (1) defining a cruciform channel formation (3, 4) for receiving cabling or the like. The channels (3, 4) have a floor (1A) defined by the base component and a removable channel cover (2). The channel cover (2) comprises one or more channel cover components for covering the channel formation, such that the channel formation and channel cover may combine to provide a closed channel for the cabling or the like. Removal of the cover (2) allows access to the channel formation from above, in use. The sides of the base component (1) define module connector clips (20, 21) for engaging with corresponding module connector clips on adjacent modules to lock the modules together in an array. The base component (1) defines retaining formations (13, 14) for engaging with and retaining the channel cover components over the channel formation. The channel cover (2) engages against one or more of the module connector clips (20, 21) when in the clips are in the closed position so as to limit deflection of the module connector clips (20, 21) and thus prevent disengagement of the module clips from the module clips of an adjacent flooring module in an array of flooring modules. The sides of the module preferably also include a plurality of levelling clips (41, 42) which define upward and downward facing engagement faces to prevent vertical misalignment of the modules.

A mat for hidden-type splicing includes a mat body and a splicing bottom base connected thereto. Sides of the splicing bottom base are formed with two adjacent convex parts and two adjacent concave parts. The convex part has a convex part connection surface disposed corresponding to and being flush with a side edge of the mat body. Outwardly convex splicing teeth are disposed on the convex part connection surface and protrude outside the side edge, and adjacent two of which have a splicing outer groove formed therebetween. The concave part has a concave part connection surface disposed corresponding to and being flush with another side edge of the mat body. Inwardly concave splicing grooves are disposed in the concave part connection surface, and adjacent two of which have a splicing inner tooth formed therebetween. The mat body completely covers the two concave parts located therebelow.

A modular attic walkway system for creating a walkway across attic joists which includes a plurality of attic joists each has a top face. A plurality of platforms is removably attached to the top faces such that each platform traverses between adjacent attic joists. Each of the platforms is releasably interlocked with an adjacent one of the platforms. Each platform includes a panel. The panel has a top surface, a bottom surface, and a perimeter surface which extends between the top and bottom surfaces. The perimeter surface includes a first mating edge, a second mating edge, a first lateral edge, and a second lateral edge. The first mating edge includes a tongue cutout which extends inwardly from the first mating edge toward the second mating edge. A tongue extension extends outwardly away from the second mating edge and releasably interlocks with a tongue cutout of an adjacently positioned panel.

A synthetic ice panel system for use on a ground surface includes plurality of substantially flat panels that mutually interlock to form a rink, such as for ice skating. Each panel includes a top surface, a bottom surface adapted for resting on the ground surface, and a peripheral edge. The peripheral edge includes a plurality of interlocking tabs and recesses operative to mutually interlock with adjacent panels. Each panel is preferably made with a high-density polymer infused with a lubricant. As such, ice skates and the like are able to slide with relatively low friction on the top surface of the panel. Weather permitting; the panels may be inverted in some embodiments wherein the bottom surface of each panel includes a cooling channel containing a cooling tube through which a coolant flows to freeze water resting on the panel, thereby forming a layer of ice above the panel.

A fixture for laying a joint-covering/threshold-covering profiled element and a kit having such fixture includes an insert to be arranged under the profiled element and which is substantially L-shaped in cross-section. The fixture further includes, with a first portion arranged parallel to the flooring surface and a second portion arranged substantially vertically at the side of the flooring surface.

A building slab pad in the form of a square plate is divided into four analogous sections, each section being formed by four linear projections on the top surface that run from the center of each edge and converge in the center of the pad. On each of the two side edges of the sections there is a trapezoidal protrusion respectively with a base narrower than the rest of the protrusion and a keyway respectively corresponding in shape to the protrusions, with two protrusions and two keyways alternating on each side edge of the pad. On the top surface there are linear top indentations running from the corners of the pad and converging in the center of the pad. On the underside are four linear bottom indentations running from the center of each edge to the center of the adjacent edge to form a square shape.

A modular tile for a walkway system interlocks with another tile to constrain movement of the interlocked tiles in all three-dimensions. The tile includes a male projection which may be tapered to provide lateral wings that are received in corresponding pockets of a female receiver of the other tile. The wings may include vertically-facing male stop surfaces that are engageable with vertically-facing female stop surfaces within the pockets. The male projection may further include a forwardly protruding ridge that is received in a corresponding groove of the female receiver of the other tile. The engagement of the stop surfaces of the wings and pockets, and the engagement of the ridge in the groove is such that the tiles are vertically interlocked with each other. The tiles may be configured to enable a pivotable interlocking connection while one tile remains on the ground.
