An apparatus is comprised of a securement base member and a self-suspending system. The securement base member includes a top end, a bottom end on an opposite side of the securement base member from the top end, a first side, a second side on an opposite side of the securement base member from the first side, a third side, a fourth side on an opposite side of the securement base member from the third side, and an opening disposed within the top end, the opening to accept a fastener. The self-suspending system is coupled to the top end of the securement base member, the self-suspending system suspending the securement base member below two portions of a surface having a slot therebetween.

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 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 spacer for support elements of a decking or paving support system, has a central region, at least two spacer arms extending laterally from the central region, and a retention portion coupled to the central region, wherein the retention portion has a longest lateral axis extending laterally and wherein the longest lateral axis lies at an angle to each of the at least two spacer arms.

A pedestal/stand for raised floors can be applied on a number of heads of supports for raised floors. The pedestal/stand may include at least one beam. The beam is of a contoured type and includes at least one zone for interlocking mechanical association with the number of heads of the supports.

Support element for spacers comprising a base provided for being placed on a surface elevation pedestal, which basis is provided with at least a first and a second window having a curved geometry, each window being provided for applying therein one of the spacers in such a manner that the spacer can be freely moved in the window in which it is applied and be guided by that window when being moved, the first and second window each having a start section and a final section, the final section of the first window and the start section of the second window being juxtaposed one to each other in such a manner that a linear axis starting from a centre of the basis in a direction towards an external border of the basis crosses successively the final section of the first window and the start section of the second window.

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 pedestal/stand for raised floors can be applied on a number of heads of supports for raised floors. The pedestal/stand may include at least one beam. The beam is of a contoured type and includes at least one zone for interlocking mechanical association with the number of heads of the supports.

Methods for using Predrill guide tools are disclosed. The predrill guide tools include a body having a vertical planar member with a front side and a back side, a horizontal planar member with a top side, a bottom side and a tapered end, and an angled drill guide with a front face positioned within a vertical plane; two or more ribs extending from a top side of the horizontal planar member, and one or more keels extending vertically from the bottom side of the horizontal planar member. Methods of using the predrill guide tools to drill holes into deck boards for use with deck clips are also disclosed.

A connector is provided for jointing two boards to have the boards mounted to and lapping over a beam. The connector has one side that is formed with an engagement slot for jointing one board and an opposite side formed with a mortise trough for jointing another board. The connector also includes a path-following hole penetrating therethrough in an up-down direction and a track channel formed in a bottom of the connector and having an opening facing downward. The engagement slot and the mortise trough have axial directions that are perpendicular to an axial direction of the track channel. The path-following hole has a bottom opening located in the center of the track channel. The connector is adjustable of the position thereof through sliding along the beam by means of the track channel for limited axial movement.
