A panel assembly includes two frame members and a plurality of panels extending between the frame members. Each panel has fastening elements at either end. The fastening elements are arranged to clip onto mating portions of the frame members, and are also arranged to frictionally engage internal surfaces of the panels to thereby hold the panels relative to the frame members.

Solar energy shade structures and methods of designing and installing the same are disclosed. These structures are capable of supporting a contiguous planar solar panel support structure at heights greater than 18 feet above their mounting surface. The planar solar panel support structure may contiguously cover at least two areas of different area types, including parking spaces and driving aisles, and may be at least 64 feet long by 64 feet wide. The planar solar panel support structure may have a high panel density defined in that an arrangement of the plurality of solar panels that is uninterrupted by service or access lanes. The majority of the plurality of solar panels may be fixed at an angle that would be non-optimal for energy generation in each individual panel of the majority of the plurality of solar panels, but results in optimal power density for the entire solar energy shade structure.

The present invention relates to a lamella front surface system (1), comprising at least one lamella (2), at least two metal mounting elements (3) each having a mounting axis, configured to be attached to a support (4), e.g. the face of a building, each of the metal mounting elements comprising mounting side (6) abutting the face in its mounted position, an interfacing side (7) arranged opposite the mounting side, the interfacing side comprising attachment means (8), wherein the lamella front surface system further comprises a fixation element (5) having a longitudinal extension (FA) and having a body (9) having a first side (10) comprising interfacing means (12, 13) configured to be connected with the attachment means, and a second side (11) configured to support the lamella in a position which is substantially perpendicular to the mounting axis of the metal mounting elements, and wherein the lamella is made from a non-metal material. The present invention also relates to use of the lamella front surface system according to the present invention.

In an embodiment, an assembly includes a first plate comprising a first primary portion and a first flange disposed orthogonally to the first primary portion. The first primary portion is configured to contact a first structural member and the first flange defining a first through hole. A second plate comprises a second primary portion and a second flange disposed orthogonally to the second primary portion. The second primary portion is configured to contact a second structural member and the second flange defines a second through hole. A cover receives the first and second flanges. A bolt is received through the first through hole, and tightening the bolt tends to draw the second plate towards the first plate.

A modular ballistic barrier assembly for deployment in proximity to a protected high value asset such as electrical grid equipment. A ballistic barrier assembly comprises a plurality of prefabricated ballistic barrier panel units that can be stacked on top of each other. Each panel unit is made of spaced apart angled steel louvers or slats, arranged in one or more sections. The louvers are arranged in one or more vertically extending, spaced apart rows, having an outwardly facing row of louvers presenting a downwardly angled surface to an approaching projectile, and an inwardly facing row of louvers presenting a second layer of ballistics protection. Steel I-beam support columns are provided at spaced apart intervals to receive and support a stack of panel units. The panel units are made to interlock with vertically adjacent, stacked panels, so that multiple panel units can be stacked.

A roof structure support allowing roof shingle having a partially tubular mounting bracket having an upper plate for securing a roof structure joist and a lower plate for securing onto a wall plate, wherein a base tube is received by a collar affixed to a roofing deck and an associated boot.

A louvered enclosure system is provided that is capable of selectively fully or partially covering a designated area to block direct sunlight, rain, snow, etc. while allowing a selected amount of airflow to the designated area. The louvered enclosure system includes a pair of longitudinally extending rails having a plurality of movable louver assemblies extending between the rails. The movable louver assemblies are rotatable relative to the rails and longitudinally movable along the rails. A drive assembly rotates and moves the louver assemblies relative to the rails. The drive assembly includes separate rotation and drive mechanisms for selectively rotating the louver assemblies and moving the at least one movable louver assembly along the rails. Insulation may be provided on the louver assemblies to aid in insulating the designated space. The louver assemblies may be maintained rotated to a closed position by magnets securing each louver assembly to adjacent louver assemblies.
