Description

Modular Overhead Bridge
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to a modular overhead bridge and, in particular to an overhead bridge and passage that enables fast deployment over a street, a road, a railroad track, or an intersection of roads.
Vehicular traffic routes include intersections, occasionally with traffic lights. The increase of traffic volume causes heavy traffic in the intersection, thus increasing the risk of accidents as a result of collision between vehicles or collision between vehicles and pedestrians. The present solutions for this common problem include the money-, time-, and land-consuming solution of constructing interchanges. This solutions include the construction of bridges that enable passage above a traffic route, for vehicles,, pedestrians* animals,, or any combination of the three.
At present, constructing a bridge for passage above an existent road, street, intersection, or railroad tracks consumes a great deal of time and causes traffic disruptions.
There is thus a widely recognized need for, and it would be highly advantageous to have, a modular bridge and a method for the construction of modular bridge and its on-site assembly in short period of time without any need, for foundations or changes in access routs. DISCLOSURE OF THE INVENTION
The present invention provides a modular bridge structure and a method for its on-site assembly in a short period of time without need for foundations or changes in access routes. The said modular bridge and the ramps attached to it are such that the weight of the parts and their suitability to the terrain create the stability and adherence to the ground surface.
According to the present invention, a modular bridge is provided, including: (a) a central unit, through and above which vehicles can pass; (b) at least one inclined unit (ramp) that enables embarkation of vehicles driven from a road onto the central unit;
According to further features in preferred embodiments of the invention, the modular bridge including: (c) at least one inclined unit of suitable angle for passage of vehicles being driven from a road through the central unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention is a modular overhead bridge and, in particular an overhead bridge and passage that enables fast deployment over a street, road, or intersection of roads. Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The materials, methods, and examples provided herein are illustrative only and are not intended to be limiting.
The main point of the invention is disposing the modular bridge such that the weight of the parts and their suitability to the terrain create the stability and adherence to the ground surface. The anchoring of the bridge in place relies on weight of its own elements. The bridge is assembled out of parts, which are adapted to each other with connectors, and can be disassembled. Seeing as there is no need for foundations, the deployment time of the modular bridge is significantly shortened, and thus reduces costs. The modular bridge can be adapted to an intersection with no need for changing the access routes to the intersection - the bridge adapts itself to the intersection ant the intersection to the bridge.
Referring now to the drawings, Figure Ia is a schematic illustration of an isometric view of a preferred embodiment of a modular bridge. The illustration shows a central unit 1 that enables passage of vehicles, pedestrians, animals, or any combination of the three, over and through it. Figure Ib is a schematic illustration of a side view of a preferred embodiment of a modular bridge 100. The illustration shows the central unit 1 and a gateway 2 within through which traffic can pass. Inclined units are disposed at both ends of central unit 1, forming the structure of the incline and decline for traffic from the lower surface, the street or road, to the upper part of the central unit 1. This structure can be comprised of one unit or more than one unit, as shown in the example in the illustration of seven units 3, 4, 5, 6, 7, 8, and 9.
Figure 2a is a schematic illustration of an isometric view of a preferred embodiment of a modular bridge's central unit 1. The illustration shows the gateway 2 within the central unit 1, through which passage is enabled, and security railings 11 that can be added optionally to the modular bridge 100, or not. The security railings 11 can be an integral part of the central unit 1, or a separate part that is attached to it. The central unit 1( for example ) is one-piece structure comprised of an upper sheet 14, upon which the vehicle or pedestrians will pass over the existent intersection. The connection between sheet 14 and the low surface can be from the sheet 16, perpendicular to the modular bridge, and can be by means of full concrete, or any other means that is sufficiently durable to withstand the necessary load and standards.
Figure 2b is a schematic illustration of a top view of a preferred embodiment of a modular bridge's central unit 1. Figure 2c is a schematic illustration of one side view of a preferred embodiment of a modular bridge's central unit 1.
Figure 2d is a schematic illustration of the other side view of a preferred embodiment of a modular bridge's central unit 1.
Figure 3 is a schematic illustration of a top view of a preferred embodiment of a modular bridge 100 after deployment over an intersection 200. The example in the illustration shows the modular bridge 100 in a T-intersection. The illustration shows vehicles 12 that can follow the arrow 13 through the modular bridge 100, under the traffic crossing its path. The modular bridge 100 can include a security railing on each of its sides or on specific segments of its length.
Fig. 4a is a schematic illustration of a top view of a preferred embodiment of a modular bridge. The illustration shows one example out of many possibilities.
Fig. 4b is a schematic illustration of an isometric view of a preferred embodiment of a modular bridge's central unit.
The invention is characterized in that modular bridge 100 can be designed, manufactured, and composed of various materials, such as concrete, metal, wood, plastic, and composite materials, and various combinations of units of various shapes and dimensions, without need for foundations or stilts. The descriptions and illustrations of the invention do not limit or restrict the invention in any way.
A major advantage of the invention with regard to the present state is that all units of the modular bridge can be manufactured; its assembly can be practiced as necessary in other suitable location and only the final assembly will be executed at the final bridge site. The units can be brought to the desired location on trolleys, wheels, trucks, or any other suitable mode of transportation; and can ultimately be deployed and assembled by mean of cranes or other suitable equipment in the exact desired place as a modular bridge, while saving a great deal of time with regard to the disruption of orderly traffic on site. The combination of the elements will be using suitable connectors that allow fast connection and, if necessary, fast disassembly, and of sufficient durability of the connectors and the modular bridge with respect to the loads it will be required to withstand.
The modular bridge 100 can have other variations which do not appear in the illustrations. Should there be any need to remove the modular bridge, it can be disassembled into its units and transported from the site.
One of the possibilities for planning the structure of the modular bridge and its unit and practicing its assembly is creating a model of the site designated for deployment of the modular bridge. Creation of the model can be performed in several ways, one of which includes applying an anti-adhesive material, or another material that can be removed latter, to the road in designated site, putting in frames and casting suitable material, such as polyurethane, in the necessary consistency. After the polyurethane hardens, its lower side can serve as a mold for casting a material suitable for withstanding the load of modular bridge. Combining these casts after they solidify creates a high-precision model of the terrain of the designated site, and additional details can be added, such as signs, traffic light poles, and various structures as they exist in the actual designated site.
Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
