A magnetic attachment assembly for attaching a first object to a second object includes a first and second ferromagnetic devices possessing an attractive magnetic property pulling each toward one another. The first ferromagnetic device is attached to the first object and an adhesive layer on the second ferromagnetic device is for attaching the second ferromagnetic device to the second object. A removable separator is initially positioned intermediate the first ferromagnetic device and the second ferromagnetic device and is frictionally held in place prior to attachment of the second ferromagnetic device to the second object. During installation, the user pushes the attachment assembly onto the second object, pulls the first ferromagnetic device away from the second ferromagnetic device, removes the separator, and then pushes the first ferromagnetic device back to the second ferromagnetic device thereby attaching the first object to the second object.

A set of decking boards including a first and a second decking board and being provided with a connecting system including a connecting device. The first board is configured to be connected to a support element and the second board is configured to assume a vertically locked state with respect to the first board in which the connecting device cooperates with the first and second boards, there is a vertical gap between a portion of the second lip of the first decking board and a portion of the second lip of the second decking board, and there is a horizontal space between a first lip of the first board and the second lip of the second board. Also, other aspects of a set of decking boards and connecting devices as well as methods for demounting decking boards and replacing them with new decking boards.

A panel assembly for installation onto a track beam including a beam flange having a non-linear edge is disclosed. The panel assembly includes a panel and a lockable catch moveably connected to the panel. The lockable catch includes a lockable mating edge configured to selectively mate with the non-linear edge of the beam flange of the track beam. The lockable catch also includes a lockable catch edge extending beyond the lockable mating edge. The lockable catch is moveable on a lower surface of the panel between an unlocked position and a locked position. In the unlocked position the lockable catch edge is retracted. In the locked position, the lockable mating edge mates with the non-linear edge of the beam flange and the lockable catch edge retains the panel on the track beam.

A tile-securing system having a polymeric wedge component positioned between two adjacent tiles that are in plane and the polymeric wedge component contacting a side edge of each adjacent tile, wherein the polymeric wedge component exerts a force against both side edges; the polymeric wedge component being secured to a solid substrate using a fastener.

A tile-securing system having a polymeric one-piece bracket having a first flange, a second flange, and a central raised-wall portion, the first flange and the second flange opposing each other and being in the same plane, the central raised-wall portion being orthogonal to both the first flange and the second flange; a slot opening located on an exterior edge of the raised-wall portion; the slot opening having a first width and a first length, wherein the first width is less than the first length, and the slot opening configured to receive a wedge that upon insertion into the slot opening expands the first width to a greater second width.

A stringer for a decking support frame, the stringer including a structural body having a front side, a back side, a top side, and a bottom side. The structural body also includes a plurality of weld free mounting tabs integral with the structural body extending from the top side and away from the bottom side. A plurality of apertures extend evenly spaced along a longitudinal length of the structural body and each aperture extends completely through the front side to the back side.

A support for installing facing materials such as ceramic tiles on a substrate, such as, floors, walls and ceilings. The support plate has a plurality of spaced apart raised portions and recesses in the plate material, and a plurality of openings extending through the top surface and bottom surface of the plate material. The openings exposing a mat layer attached to the bottom of the support plate. Support plates of the invention are used for tile installations between a substrate and tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the openings forming a continuous bond between the mortar, openings and mat layer to provide a strong bond between the support plate, mortar and the tiles.

In one embodiment of a tile and support structure, the tile and support structure may be configured to engage a tile such that the tile is oriented in a generally vertical plane. The support structure may include a riser tile engaged with both an upper riser support structure and a lower riser support structure.

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 board engagement elements. The board engagement elements can engage the groove of the board, 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.

An adjustable support for supporting a raised floor above a ground surface through a post is described herein. The adjustable support generally includes a base threadably engaged to a post engagement structure, where rotation of the post engagement structure relative to the base brings the post engagement structure into supportive contact with the bottom end of the post. The base includes a large diameter bottom plate that is able to distribute the load of the raised floor over a large ground area to prevent unacceptable compaction of the soil that would cause sinking. Buttress threads are configured to bear the load of the raised floor and enable the adjustable supports to be permanently installed. Because the adjustable support is made of a polymer material, it resists rotting and deterioration.
