FIELD OF THE INVENTION
This invention relates to airfield repair, and more particularly to a combination traffic barrier and airfield repair system.
DISCUSSION OF RELATED ART
Portable traffic barricade systems are known in the art, and are typically adapted to be placed by truck or crane in a series of abutting barricades to quickly protect a jobsite or other sensitive area, or simply to direct traffic. However, even though such barricades are made from concrete, prior art barricades are not well suited to aid in roadway or runway repair, which often requires a large, flat slab of uniform thickness.
Therefore, there is a need for a system that can double as both a traffic barricade and a roadway or runway repair aid. Such a needed invention would provide means for securing a plurality of such barricades together to form an elongated connected barricade. Such a needed system would further provide aircraft tie-down anchors in the event of use as a runway repair aid. The present invention accomplishes these objectives.
SUMMARY OF THE INVENTION
The present device is a combination traffic barrier and roadway repair system for use on a roadway, such as an automotive road, bicycle road, airplane runway, taxiway or tarmac, bridge, or the like. An elongated base comprises a top surface, a bottom surface, a rear surface, a front surface, and two opposing side surfaces. The top surface includes a groove formed therethrough and traversing the base between both opposing side surfaces.
An elongated rectangular slab comprises a top surface, a bottom surface, a substantially flat front surface and opposing substantially flat rear surface, and two opposing side surfaces. The slab is preferably a rectangular solid and is adapted for upright placement within the groove of the base. The base holds the slab upright while stored therein, and provides a relatively tight clearance so that the slab does not have significant room to tilt back and forth while contained within the base.
In use, with the elongated base resting on the roadway or nearby, and with the slab placed upright within the groove of the base in a first operative position, the system provides a traffic barrier that significantly inhibits breach thereof by vehicles or pedestrians. In the event of roadway damage, such as in the case of war or sabotage, the roadway may be relatively quickly prepared to receive the slab with the front surface facing upward and flush with the roadway so that normal traffic operations may quickly resume. In such a case, the base remains as a partial traffic barricade while the slab is used as a quick roadway or runway repair patch.
To facilitate such moving of the base and the slab, either preferably include a plurality of anchors embedded at least partially therewithin and suitable for use with crane hooks or the like. Further, the anchors are preferably adapted for use as aircraft tie-downs as well.
The present invention is a system that can double as both a traffic barricade and as a roadway or runway repair aid. The present invention provides means for securing a plurality of such barricades together to form an elongated connected barricade, and further provides aircraft tie-down anchors in the event of its use as a runway repair aid. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

FIGS. 1-3 illustrate a combination traffic barrier and roadway repair system 10 for use on a roadway 15, such as an automotive road, bicycle road, airplane runway, taxiway or tarmac, bridge, or the like.
An elongated base 20 comprises a top surface 29, a bottom surface 21, a rear surface 28, a front surface 22, and two opposing side surfaces 25. The top surface 29 includes a groove 30 formed therethrough and traversing the base 20 between both opposing side surfaces 25. The groove 30 is preferably uniform such that the cross-sectional shape of the groove 30 is consistent from one side surface 25 to the opposing side surface 25.
Preferably the front surface 22 of the base 20 includes at least a first angled surface 100, having an angle α of between 40 and 60-degrees with respect to vertical. Another second angled surface 110 may be included, having an angle β of between 1 and 10-degrees with respect to vertical. As such, the bottom surface 21 is larger in plan view than the top surface 29 of the base, giving the base 20 greater tilt stability on the roadway 15. Further, such angled surfaces 100,110 allow at least a portion of impact forces from vehicles or the like to be deflected upwards, maintaining the base 20 on the roadway 15 and inhibiting breach of the traffic barrier formed thereby.
An elongated rectangular slab 40 comprises a top surface 49, a bottom surface 41, a substantially flat front surface 42 and opposing substantially flat rear surface 48, and two opposing side surfaces 45 (FIGS. 3-5). The slab 40 is preferably a rectangular solid and is adapted for upright placement within the groove 30 of the base 20. The base 20 holds the slab 40 upright while stored therein, and provides a relatively tight clearance so that the slab 40 does not have significant room to tilt back and forth while contained within the base 20. Gravity firmly holds the slab 40 within the base 20, and the base 20 is adapted to have a large enough bottom surface 21 so as to inhibit tipping of the base 20 and slab 40 even if experiencing a significant impact force or wind or weather force.
In use, with the elongated base 20 resting on the roadway 15 or nearby, and with the slab 40 placed upright within the groove 30 of the base 20 in a first operative position 50 (FIG. 1), the system 10 provides a traffic barrier that significantly inhibits breach thereof by vehicles or pedestrians. In the event of roadway damage 15, such as in the case of war or sabotage, the roadway 15 may be relatively quickly prepared to receive the slab 40 with the front surface 42 facing upward and flush with the roadway 15 (FIG. 1) so that normal traffic operations may quickly resume. In such a case, the base 20 remains as a partial traffic barricade while the slab 40 is used as a quick roadway or runway repair patch.
The base 20 is preferably made of concrete, reinforced concrete, composite material, relatively strong plastic or rubber material that is able to withstand relatively high compression force, or the like. The slab 40 is preferably made of concrete, reinforced concrete, heat resistant concrete or the like suitable for a class A traffic area (UFC 3-260-02). As such, moving either the base 20 or the slab 40 requires a heavy vehicle with craning capabilities. To facilitate such moving of the base 20 and the slab 40, either preferably include a plurality of anchors 70 embedded at least partially therewithin and suitable for use with crane hooks or the like. Further, the anchors 70 are preferably adapted for use as aircraft tie-downs as well. Such anchors 70 are advantageously embedded in the top surface 29 and/or side surfaces 25 of the base 20, and the top surface 49, front surface 42, and/or side surfaces 45 of the slab 40.
In some embodiments, the slab 40 is mechanically fastenable with the elongated base 20 in the first operative position 50 with at least two mechanical fasteners 80, such as long stakes 80 that traverse apertures at least partially through the base 20 and slab 40 (FIG. 1). Further, some embodiments may include a two-part fastening system 90 comprising two parts 91,92 thereof, each part 91,92 fixed with adjacent side surfaces 25 of abutting bases 20. As such, a plurality of the bases 20 may be fastened together to form a multiple-base traffic barrier (FIG. 1). Optionally a metal cable or rod 120 may be fixed between parts 91,92 of the two-part fastening system 90 on opposing sides surfaces 25 of the base 20, thereby providing additional tensile strength between the side surfaces 25 and strengthening the multiple-base traffic barrier.
While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, the slab 40 may take other shapes than rectangular solid or disk shapes. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
