A skylight cover is provided that includes a light transmitting body including first and second integral lenses. The first and second integral lenses define polygonal perimeters, each polygonal perimeter having a first element and a second element residing therein, the first and second elements disposed adjacent to each other in each instance. The skylight cover may include a plurality of ridges and creases, the individual, respective ridges and creases disposed in advantageous configurations. The cover may likewise include a plurality of surfaces, some optionally parallel and some optionally co-planar.

The present invention is a curb assembly system for modifying a metal building. The apparatus comprises a plurality of mounting brackets, at least two caps, at least two side rails, at least two end panels, and a plurality of screws. The mounting brackets are placed on support structure of the building, one of the at least two end panels is placed at the low point of the building, one of the at least two side rails is placed on the edge of an existing building panel, the at least two caps are placed a determined distance from each other, another of the at least two side rails is placed parallel to the first side rail, and another of the at least two end panels is placed at the high point of the building, such that there is created a curb comprised of the side rails and caps which can support an device or feature that is secured thereon.

The invention is related to the field of civil engineering, particularly related to the translucent roofs of buildings, and regards the production of polycarbonate dome structure or translucent material, made of double lens and tube formation, which allows the installation and mounting of the same in-line, in the roofing structures, targeting design and extending day light in the inner area of buildings, even at low climatic condition, reducing the passage of excessive heat into the environment to be illuminated. In addition to reducing heat passage by approximately 30%, its use installation will take place linearly and non-point, so that natural light is distributed more homogeneously in the environment. The material for its manufacture can come from prismatic polycarbonate, acrylic or other compatible material and its manufacturing process adopts vacuum system forming (thermoforming).

Lighting devices and methods for providing daylight to the interior of a structure are disclosed. Some embodiments disclosed herein provide a daylighting device including a tube having a sidewall with a reflective interior surface, a light collecting structure, and a light reflector positioned to reflect daylight into the light collector. In some embodiments, the light collector is associated with one or more light-turning and/or light reflecting structures configured to increase the amount of light captured by the daylighting device. Optical elements may allow for the absorption and/or selective transmission of infrared light away from an interior of the daylighting device.

A load support structure supports a load on a metal panel roof. Such load support structure includes multiple closure members including opposing side rails, and optionally end closures. The rails are mounted on roof panel ribs. Cavities can be disposed inwardly of the outer perimeter of the support structure as defined by the closure members, in upper portions of the closure members. Rods may be inserted through slot-shaped openings, into the cavities. Cross-section dimensions of the rods are less than the widths of the cavity openings. Either the rods are compressed, or the cavity openings are expanded, or both, so as to enable manually inserting the rods into the cavities. Elongate thermal breaks may be installed at and adjacent the cavities, to assist in controlling thermal conduction through the closure members, between the outside environment and the enclosed space above the roof opening.

A roof load support structure supports a load on a sloping metal panel roof such that substantially all of the load is conveyed through rails, which are mounted on roof panel ribs, then through the roof panel ribs, and to underlying building support structure. Minor portions of the load can be conveyed through an upper diverter and a lower closure. The upper diverter diverts water laterally away from the support structure, in two opposing directions to two opposing sides of the support structure.
