An apparatus and methods lock together pavers on a roof deck to reduce uplift pressure and increase stability and strength in a variety of environmental conditions. More specifically, a paver lock apparatus is placed in grooves on the top side of a multiple of pavers and locked to a stationary object, such as the roof or a pedestal placed on the roof underneath the deck. Roof pavers are manufactured with grooves on the paver surface to hold the paver lock apparatus. The pavers are loose laid on paver pedestals and the paver lock apparatus is laid into the grooves of multiple adjacent pavers and locked into place by connecting the paver lock apparatus to the paver pedestal.

A hidden deck fastener or clip has a H-shaped body having a top portion having a thickness, a top surface and a bottom surface, and an integrally formed leg extending downwardly from the bottom surface, the leg defines channels in opposing sides thereof. A stepped fastener receiving opening is formed in the top portion and the leg. The opening has a first region formed into a part of the thickness of the top portion and a second region aligned and contiguous with the first region extending through the leg. The first region is a counterbore having a flat bottom. The fastener has a pull-out force resistance at least 50 percent greater than a comparable fastener having a countersink fastener receiving opening.

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 decking assembly comprising a first decking panel (202), a second decking panel (202) adjacent the first decking panel (202), a clip (100) comprising a base (102) and a retaining portion (104), wherein the retaining portion (104) cooperates with the first decking panel to affix the clip thereto, the base projects from the first decking panel to engage the second decking panel and, the base defines a fastener opening for receiving a fastener to secure the first and second decking panels to an underlying substrate.

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 extending from a portion of the spacer block. The board engagement elements can clamp the board, between an upper and/or lower surface of the board and a 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 installation clip for installing assembly pieces includes a holding arrangement with a first holding element and a second holding element that are arranged symmetrically inside the holding arrangement. The first holding element is configured to interlock with a first receiving element of a first assembly piece and the second holding element is configured to interlock with a second receiving element of a second assembly piece. The first holding element and the second holding element are configured elastically to be held by a preload inside the first receiving element and the second receiving element.

One or more hidden clips can be efficiently fastened and mounted to decking planks, e.g., with a tool or manually. A plurality of hidden clips can be included with a strip of clips and separated by a frangible section or tab located between adjacent clips. Each hidden clip can include a leading edge and a trailing edge opposite the leading edge. The leading edge can be beveled or tapered across an entirety thereof. At least one connecting tab spans between a respective leading edge and trailing edge of adjacent decking clips in the clip strip. Each of the decking clips can include an aperture configured to receive a fastener. A fastener can be disposed in the aperture in each clip such that each fastener extends partially above a top surface of the decking clip.

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.

A decking system including floor elements and a connecting system including a connecting device for connecting a first and a second floor element, wherein the connecting device is removably connectable to a support member. A first and a second connecting portion of the connecting device are configured to cooperate with a first and a second engagement portion, respectively, of the first and second floor elements for vertically connecting the first and second floor elements. The connecting device further includes a displaceable portion which is horizontally displaceable and is configured to assume a first and a second horizontal state, wherein a horizontal extension of the connecting device in the second horizontal state is smaller than a horizontal extension of thereof in the first horizontal state.

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.
