The present invention provides a fastener alignment guide comprising a generally planar body and an angled element arranged at an acute angle θ to the body, a first aperture arranged through the angled element and a second aperture arranged through the body, wherein the first aperture and the second apertures are aligned such that a fastener may be inserted progressively through the first and second apertures in use. The present invention also provides a slip-resisting fastener alignment guide comprising a body at least partially arranged in a first plane, the body comprising a first aperture for receiving, in use, at least a portion of a shank of a fastener; and a guidewall extending out of the first plane for guiding the fastener, in use, into the first aperture at an acute angle α to the first plane, wherein the guidewall comprises a first bearing edge or surface upon which an underside of a head of the fastener can bear in use, the body further comprises a second bearing edge or surface upon which the underside of the head of the fastener can bear in use, and the first bearing edge or surface and the second bearing edge or surface are each configured/arranged to resist movement, in use, of the fastener alignment guide relative to the fastener in a first direction parallel to the first plane.

The present invention also provides a method of forming the fastener alignment guide and slip-resisting fastener alignment guide.

An arrangement for fastening first and second components with automatic compensation in spacing between the components has a base element with first and second axial ends and a holding structure for holding the base element in an opening of the first component. An adjusting unit screwable into the base element has a driver unit. A fastening screw is connectable to the adjusting unit via the driver unit, such that, when the fastening screw is rotated, the adjusting unit can be rotated conjointly and moved into contact with the second component. The holding structure has a holding segment arranged such that, by the holding segment, an angle between the first and second component can be compensated such that, when the adjusting unit makes contact with the second component, a longitudinal axis of the fastening arrangement runs perpendicular to a plane of the second component.

An internal splice joint that facilitates coupling of a pair of joist members together is provided. The internal splice joint includes a main wall, first and second side flanges, and first and second end flanges. The first side flange extends upwardly from the main wall. The second side flange extends upwardly from the main wall and is spaced from the second side flange. The first end flange extends from the first side flange. The second end flange extends from the second side flange. The first end flange and the second end flange extend inwardly towards each other and are spaced from each another. A joist assembly that includes the internal splice joint is also provided.

Example embodiments provide systems and methods for coupling prefabricated panels to a structure. One example system provides a system for coupling a prefabricated panel to a structure. The system may comprise a first member. The first member may be couplable to a framing structure of the prefabricated panel. The system may also comprise a second member. The second member may pivot relative to the first member. The system may also comprise a fastener. The fastener may be configured to bias the first and second members together such that a component of the structure is at least partially receivable between the first and second members and tightening the fastener reduces a distance between the first and second members.

A modular structure system of detachable members, the system includes a support pillar and various connectors. The support pillar has a main body and a plurality of channel walls outwardly radiating from an outside surface of the main body. The channel walls are disposed lengthwise on the main body from one terminal end of the main body to another terminal end of the main body. The support pillar has a symmetrical cross-sectional shape and each of the channel walls has an expanded distal end forming two lips.

The disclosure is directed to an elongated geodesic dome with an arched-tunnel section. In some embodiments including: a first adjustable angle hub connector, the first adjustable angle hub connector being a connector of a first plurality of tubular struts, the first plurality of tubular struts being inserted into the first adjustable angle hub connector; a second adjustable angle hub connector, the second adjustable angle hub connector being a connector of a second plurality of tubular struts, the second plurality of tubular struts being inserted into the second adjustable angle hub connector; a third adjustable angle hub connector, the third adjustable angle hub connector being a connector of a third plurality of tubular struts, the third plurality of tubular struts being inserted into the third adjustable angle hub connector. The adjustable angle hub connectors may be removable for adjusting a length of the arched-tunnel section of the elongated geodesic dome.

A hybrid wall system includes studs with spacers interspersed between the studs. The spacer is a flat elongate member with at least one hook-like member on each end of the elongate member to secure ends of the elongate member between two studs. At least one snap member on each end of the elongate member is removed to remove the spacer to release the spacer between the two studs. The system further includes a base track and a top track with a slip spacer assembly used to level the tops of the studs. A drop-in ceiling is placed on top of the leveled studs. A leveling assembly on the base track is used to raise and lower at least one of the studs for purposes of attaching cladding to the at least one stud.

A slide clip includes a first plate and a second plate coupled at a juncture. The first plate and the second plate form an angle at the juncture. The second plate has a first elongated slot, a second elongated slot, and a third elongated slot, each extending parallel with the juncture. The first elongated slot and the second elongated slot are each offset from the juncture a first distance. The third elongated slot is offset from the juncture a second distance that is greater than the first distance.

This invention improves seismic resistance of structures by transition from stiff to non destructible flexible state at a threshold earthquake level higher than prior art maximum design earthquake level of stiff structures. Functional characteristics of the category of auto-reversing stiff-to-flexible seismic structures comprise: a limited six degree of freedom motion; a laterally-stable limited rising-twist-sway ascent; a self-centering diagonal-untwist auto-descent; a multidirectional flexibility; and a multi-phase split-force-impact seismic protection. Seismic construction technologies of the category of structures comprise: base split-force-impact technology; cluster split-force-impact technology; tuned segment split-force-impact technology; and tuned spine split-force-impact technology. The auto-reversing stiff-to-flexible seismic joints of the structures are low-cost, simple and easy to manufacture, and especially suitable for mass industrial application.

A booth includes a replaceable side wall that surrounds an internal space to be used by a user, and the side wall is provided with at least one entrance/exit door.
