A heavy cycle grating system incorporating a plurality of toothed support members to support a plurality of grate slats while securing them within grating assembly. This configuration allows the present grating system to accommodate higher volume of heavy use, such as found with vehicular applications. Further provided is a grating assembly configured for longer life and improved damage and wear-resistance while simultaneously reducing noise generated during use thereof.

A structural insulation panel (SIP) is made of a central insulation material or block core covered with cementitious material. The layers of cementitious material are reinforced with fiber mesh sheets, rebar and corner blocks. The corner blocks are held in thickened cementitious material edges by reinforcement pins that are fixed to the corner blocks. The corner blocks are accessible for lifting the panel and for assembling multiple panels to build a wall.

The invention concerns a method for installing a hatch (34) to a subsea structure (10) by connecting the hatch to the subsea structure by at least one hinge (20) having a first mounting portion (21), a second mounting portion (22), a flexible portion (23) interconnecting the first and second mounting portion allowing a pivot connection between the first and second mounting portion. The installation steps comprise •—inserting a protrusion (23) of the first mounting portion (21) into an installation hole arranged in the subsea structure (10), •—inserting a protrusion (24) of the second mounting portion (22) into an installation hole arranged in the hatch (34), thereby •—engaging the first mounting portion (21) of the hinge (20) for anchorage with the subsea structure (10) and engaging the second mounting portion (22) for anchorage with the hatch (34) thereby arranging for the hatch to pivot between a closed and an open position about a pivot axis provided by the flexible portion of the hinge. The invention also concerns a hinge and an assembly for subsea use.

An exterior wall panel apparatus and system is disclosed which assists in the rapid construction of manufactured homes and commercial buildings, and which replaces traditional building materials with a full composite system and materials, to extend and increase the protective capabilities of traditional residential, industrial and commercial structures

An improved drop/suspended ceiling system which provides consistent spacing between continuous, parallel support rails is described. The rails attach directly to floor joists which permits locating ceiling panels as high as possible with respect to the bottom of the joists. In other embodiments, the rails may be supported by hangers, but held in parallel by spacers hidden by the ceiling panels to avoid the use of conventional suspended ceiling cross-sectional members. In some embodiments, the rails attach within or between joists and can also be used as a remodel or new option. Panels can be used with existing steel drop ceilings in conjunction with the spacer channel to achieve a continuous, parallel look with traditional steel drop ceiling rails using the spacer. Rails and tiles can serve as a direct replacement for traditional tiles or long panels can be used from wall to wall in isles or small rooms.

A grate apparatus for covering a pit defined in a floor of a vehicle wash facility includes a plurality of rigid rung pieces having a first end, a second end, an upper surface and a lower surface. The rigid rung pieces are secured in generally parallel and spaced apart fashion by a plurality of flexible strap members. The flexible strap members are secured to each of the rung pieces by a plurality of fasteners. The grate apparatus is moveable between an unwound position where the first end of each of the plurality of rigid rung pieces rests on one of a pair of spaced apart rails located adjacent the pit and the second end of each of the plurality of rung pieces rests on the other of the pair of spaced apart rails and a wound position wherein the plurality of rung pieces and the plurality of flexible straps are oriented in generally coiled position around a centerline.
