(10) As shown in
(11) One or more screws, bolts, or other coupling mechanisms may be used to help couple the transparent or translucent panel 1 to the bridge beams 2, for example, via one or more angles 4. For example, at least one screw, bolt, or other coupling mechanism may be coupled to each side (e.g., longitudinally, or the left and right sides, as shown in
(12)
(13) As shown in
(14) In one aspect, the bridge beams 2 may each include bottom flanges 2A and top flanges 2B with cross-sectional widths of, for example, between approximately ten inches and approximately four feet and one inch, for example, approximately two feet and six inches. The bridge beams 2 may be spaced any distance away, and bridge beams 2 of a single bridge may have variable spacings. For example, the centers of the bridge beams may be spaced away by, for example, between approximately four feet and approximately ten feet. In one example, the bridge beams 2 may be spaced apart by approximately six feet and five inches. Accordingly, edges of the bottom flanges 2A and the top flanges 2B may be spaced apart by approximately four feet, for example, approximately three feet and eleven inches. In this aspect, the transparent or translucent panels 1, 11 may be approximately the same or slightly less than the distance between the bottom flanges 2A or the top flanges 2B of the bridge beams 2. For example, the transparent or translucent panels 1, 11 may include a width of approximately three feet and nine inches. In this aspect, there may be a small gap (e.g., approximately 1-2 inches, for example, approximately 1.5 inches) between the edges of the transparent or translucent panel 1 and the bridge beams. The angles 4 may span the gap(s) between the transparent or translucent panels 1, 11 and the bridge beams 2. Additionally, the translucent or transparent panels 1, 11 may include a length (e.g., into the page of
(15) Alternatively, as discussed with respect to
(16) Furthermore, in any of the aspects discussed herein, the transparent or translucent panels 1, 11 include a height. The height of the transparent or translucent panels 1, 11 may vary depend on the desired loading requirements, length of the transparent or translucent panels 1, 11, etc. In some aspects, the transparent or translucent panels 1, 11 may include a height between approximately 0.5 inches and approximately 8 inches, for example, between approximately 1.5 inches and approximately 6 inches, for example, approximately 2.5 inches.
(17) In any of these aspects, the transparent or translucent panels 1, 11 may include a weight of approximately 80 pounds or less, for example, approximately 65 pounds, such that contractors or other professionals, for example, two contractors, may lift and maneuver each of the transparent or translucent panels 1, 11.
(18) Although not shown, the transparent or translucent panels 1, 11 may be suspended (e.g., hang from) from the existing bridge deck, rather than being mounted on or otherwise supported by the bridge beams 2. For example, the transparent or translucent panels 1, 11 may be clamped to the existing girders (e.g., steel girders) for support and be positioned below the bridge deck.
(19) The components and/or materials of the transparent or translucent panels 1, 11 may be configured to support the loading from construction activities, wind, and impact from falling material. In some aspects, the transparent or translucent panels 1, 11 may include a plurality of transparent or translucent sheets. For example, the plurality of transparent or translucent sheets (e.g., thinner sheets of the transparent or translucent material) may be stacked vertically to form multiple layers of transparent or translucent material in a position below the bridge deck 3. In one example, the transparent or translucent sheets may be flat. In another example, the transparent or translucent sheets may be corrugated. In any of these examples, the transparent or translucent sheets may include a rubber modifier, for example, for improved impact resistance. In this aspect, the rubber modifier may be added to the material (e.g., a mixture of acrylic plastic pellets) in various percentages or ratios during the process of making the transparent or translucent sheets. In another aspect, the material used to form the transparent or translucent sheets may be naturally or inherently impact resistant, for example, when the transparent or translucent sheets are formed of a polycarbonate.
(20) In some aspects, the material used to form the transparent or translucent sheets may change color (e.g., darken, yellow, etc.) over time and/or when exposed to ultraviolet (UV) light, for example, when the transparent or translucent sheets are formed of a polycarbonate. In this aspect, a UV modifier may be added to the material (e.g., a mixture of polycarbonate pellets) in various percentages or ratios during the process of making the transparent or translucent sheets. The UV modifier may help to prevent, reduce, counteract, or otherwise negate the effect(s) of UV light on the transparent or translucent sheets. In other aspects, the material used to form the transparent or translucent sheets may be naturally or inherently resistant to UV light, for example, when the transparent or translucent sheets are formed of an acrylic. Furthermore, in any of the aspects discussed herein, the transparent or translucent sheets may be formed in accordance with one or more specifications, for example, an ASTM specification (e.g., ASTM D4802).
(21) As mentioned above, as shown in
(22) Furthermore, as shown in
(23) As discussed herein, the transparent or translucent panels 1, 11 may be formed of one or more materials that is at least partially transparent or translucent, for example, allowing a substantial or majority of light to pass through the material. In this aspect, an inspector may view one or more portions of the bridge deck 3 through the transparent or translucent panels 1, 11. The transparent or translucent panels 1, 11 may be formed of, for example, one or more of, for example, a variety of commercially available materials, such as glass polymer composites, polycarbonate, fiber reinforced polymer, fiberglass, and poly (methyl methacrylate) also known as Plexiglass, Lucite, and Perspex.
(24) The transparent or translucent panels 1, 11 and the mounting systems 10, 20 discussed herein may be positioned below existing bridge decks 3 and coupled to existing bridge beams 2. The transparent or translucent panels 1, 11 do not have openings, so material (even smaller pieces of material) does not pass through the transparent or translucent panels 1, 11. When the transparent or translucent panel 1 are positioned on or near the lower or bottom flange 2A, as shown in
(25) The transparent or translucent panels 1, 11, when assembled, may have a weight that is approximately 10 pounds per square foot or less, for example, approximately, six pounds per square foot or less. The additional weight from the transparent or translucent panels 1, 11 when coupled to the bridge beams 2 or to the bridge deck 3 may be less than panels formed of lumber, fencing materials, etc., which may help to improve the load carrying capacity of the bridge beams 2 and/or of the bridge deck 3. Furthermore, in some aspects, the transparent or translucent panels 1, 11 may be fairly lightweight, for example, approximately 80 pounds or less, or approximately 65 pounds. In these aspects, two people may handle (e.g., lift, manipulate, etc.) the transparent or translucent panels 1, 11, for example, without the need for additional lifting equipment (e.g., a crane).
(26) Furthermore, the transparent or translucent panels 1, 11 and the mounting systems 10, 20 discussed herein may be removed and relocated to a different location (e.g., below a different bridge) once the bridge deck 3 is repaired, replaced, sufficiently inspected, etc. Additionally, if the transparent or translucent panels 1, 11 are damaged, for example, during the repair of the bridge deck 3, the transparent or translucent panels 1, 11 may be repaired or replaced. For example, the transparent or translucent panel 1 between two adjacent bridge beams 2 may be repaired or replaced. In another aspect, one or more portions (e.g., sections, layers, etc.) of the transparent or translucent panel 1 may be replaced when damaged, worn down, or otherwise in need of replacement. For example, referring to
(27) Accordingly, the transparent or translucent panels 1, 11 and the mounting systems 10, 20 discussed herein form a modular system that may be used multiple times, for example, allowing for reuse of materials, reducing waste, reducing overall costs, etc. The transparent or translucent panels 1, 11 and the mounting systems 10, 20 discussed herein may be manufactured and/or supplied as a kit, as many components (e.g., angle 4) may be standard components to support the transparent or translucent panels 1, 11. Furthermore, the size and/or shape of the transparent or translucent panels 1, 11 may be easily modified or adjusted for particular bridge, for example, based on particular spacings between the bridge beams 2, a desired panel thickness, etc. Additionally, the transparent or translucent panels 1, 11 may be resistant to corrosion. The transparent or translucent panels 1, 11 may be able to withstand various types of weather and/or otherwise withstand exposure to the elements. For example, the transparent or translucent panels 1, 11 may be more resistive to corrosion than lumber, for example, as the transparent or translucent panels 1, 11 do not absorb water, do not rot, etc.
(28) Accordingly, the transparent or translucent panels 1, 11 and the support systems 10, 20 detailed above may be manufactured at reduced costs compared to other support systems. For example, the transparent or translucent panels 1, 11 and the support systems 10, 20 detailed above may be manufactured using a simple, repeatable, and modular process. The support systems 10, 20 may be modular to help in reducing the material cost over time, which may make it simple for contractors, or other suitable professionals, to install.
