The present invention is directed to a covering for a clamping assembly used to connect and ground solar panel modules to a mounting rail. The covering comprises a sleeve including an outer cover for connecting to the solar panel module and a connector shaped to be contained within the outer cover and connected to the outer cover through two or more flanges. The connector has an opening there through to receive a female member of the clamping assembly.

An adapter includes a housing and a shaft receiving port defined in the housing. The shaft receiving port defines grooves extending at least partway along the shaft receiving port. The grooves include a set of first grooves and a set of second grooves, where at least one of the first grooves is different from at least one of the second grooves. Another adapter for coupling a device to a track includes a housing defining a threaded port and a shaft receiving port; a track retention arrangement including a foot and a threaded post extending from the foot, where the threaded post is rotatably engaged with the threaded port of the housing to raise or lower the foot relative to the housing; and a locking mechanism including an actuator and a plunger coupled to the actuator and configured to extend from the housing into the track channel of the track.

A hanger for suspending a load from a metal decking is described. A first hanger includes a body having ends that may be placed between opposing metal decking grooves and a separate assembly placed through an aperture in the body and adapted to support a load. The hanger thus permits the load to move side-to-side in the hanger, thus lessening the impact of seismic events on the hanger. A second hanger attaches two bodies, each having ends that may be placed between opposing metal decking grooves and a separate assembly placed through an aperture in the body used to attach the bodies to a strut channel. An additional assembly attached to strut channel is adapted to support a load. A hanger and method are also presented for preventing damage to concrete-filled metal decking hangers resulting from a seismic event.

A mount is provided for mounting a plate to a frame assembly. The mount includes a generally cylindrical head extendable through an aperture the plate and having an upper surface, a lower face, an outer peripheral surface, and a mounting rail receivable in a slot of the frame member of the frame assembly. The cylindrical head includes a bolt-receiving bore extending through the cylindrical head along a bore axis at an acute angle to the upper face that is adapted to receive a bolt therethrough. A flange extends radially extending from the outer peripheral surface of the cylindrical head. The flange has a diameter greater than the diameter of at least a portion of the aperture through the plate. Tightening of the bolt captures the plate between the flange and the frame member.

A system and method for building a solid wall with a drop-in ceiling includes a floor track to be secured on a base floor. A support structure of studs is to be secured to the floor track. Cornice rails are to be placed on top of the studs. Splice plates are to connect ends of the cornice rails together. A top cladding is to be installed to at least a portion of the studs at a fixed distance below the top of the studs. The top cladding is to be installed prior to the cornice rails being secured to the top of the studs. Ceiling mounts are to be installed on top of the cladding in a manner that provides equal spacing reveals between the ceiling mounts and the cladding. Splice plates are to connect ends of the ceiling mounts together. A secondary cladding is to be installed to the studs. To complete the wall system, a drop-in ceiling is secured on top of the ceiling mounts.

A connecting assembly for connecting two structures of an aircraft, the connecting assembly including a central element featuring a through-hole, preferably a bore, configured to make a connection with one of the two structures by virtue of a fastener element including a shank inserted into the through-hole. The connecting assembly further includes a plurality of shock-absorbing elements made from a deformable material. Each of the shock-absorbing elements are, on the one hand, secured to the central element and, on the other hand, configured to bear against a surface of the other of the two structures. An aircraft part includes such a connecting assembly.

Provided herein is a fastener that may be used to secure objects to a channel strut or attach a channel strut to a structure. In an arrangement, the fastener is a fastener block configured for disposition within the interior of a channel strut. The fastener block has a body that includes at least one pair of spaced apart and parallel recesses (e.g., recessed channels) sized to engage the inward lips of the strut channel. Once the pair to recessed channels engage the strut channel lips, the fastener block is prevented from rotating. At least one aperture extends through the fastener block between the parallel recessed channels. A fastener recess (e.g., hexagon recess) is recede into the block around the aperture. A standard nut or bolt may be inserted into the fastener recess.

The present invention provides an improved locking mechanism for securely connecting modular or detachable components. The locking mechanism includes a male and female portion associated with, respectively, a first and second modular component, the male portion having a slit defining a first and second finger, the locking mechanism having a spreading means provided by a pressure bolt mechanism including a pressure bolt, wherein the pressure bolt is configured to, when turned by up to substantially 1 revolution, move the first and second fingers from a closed position wherein the first and second fingers are substantially parallel to one another, to a spread position wherein the first and second fingers abut an interior surface of the female portion, thereby connecting the first and second modular component.

A walkway installation includes a walkway assembly which includes at least one tread module supported by a pair of spaced apart elongate supports which extend in the direction of the length of the walkway installation, the walkway installation additionally including a handrail assembly including a handrail which extends in the direction of the length of the walkway assembly and a plurality of spaced apart posts which each secure the handrail relative to the walkway assembly, the handrail assembly additionally including a first connector which secures a post to one side of the walkway assembly and the first connector having secured thereto a substantially inflexible transverse link which extends across the walkway assembly in a direction perpendicular to the length of the walkway installation, the transverse link extending to a second connector secured to the other side of the walkway.

Mounting clamps may be utilized to quickly and easily secure solar panel modules relative to mounting rails, which may in turn be secured relative to a mounting surface (e.g., a roof). The mounting clamps may be configured to quickly secure the solar pane modules relative to the mounting rails by tightening a tightening element to pull a clamp element toward the surface of a mounting rail, thereby clamping a portion (e.g., a frame) of a solar panel module between the clamping element and an outer surface of the mounting rail.
