DETAILED DESCRIPTION

It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of various embodiments. Specific examples of components and arrangements are described below to simplify the disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

FIGS. 1 and 3 are plan views of examples of sections of a passive vehicle barrier (PVB), generally denoted by the numeral 10, according to aspects of this disclosure. FIGS. 2 and 4 are elevation views from an attack side of the PVBs illustrated respectively in FIGS. 1 and 3.

PVB 10 is configured to stop the penetration of a motor vehicle that crashes into the barrier. PVB 10 should fully stop any impacting vehicle within a desired penetration distance, for example, to keep explosives carried by the vehicle at a selected standoff distance from facilities located within the barrier perimeter. United States federal agencies (e.g., the U.S. Department of Defense (DOD) and the Department of State (DOS)) have developed test standards using crash tests to quantify, verify, and certify barrier performance. Such test methods were initially published by the U.S. Dept. of State in 1985 as SD-STD-02.01, which was revised in 2003 as SD-STD-02.01 Revision A, and which was replaced in 2009 with ASTM F2656 (Standard Test Method for Vehicle Crash Testing of Perimeter Barriers). Embodiments of PVB 10 are configured to be crash-rated by certifying agencies such as DOD, DOS, ASTM and British Standards (BSI). Vehicle barriers are tested by crashing a motor vehicle from a perpendicular direction into the barrier. The vehicle barrier is rated based on the test vehicles weight, the speed of impact, and the penetration of the vehicle (e.g., the cargo bed) beyond the pre-impact inside edge of the barrier. For example, a “K” or “M” designates a medium duty vehicle with a gross weight of 15,000 pounds (6810 kg). The speed ratings include K4/M30 for traveling at 28.0 to 37.9 miles per hour (mph), K8/M40 traveling at 38.0 to 46.9 mph, and K12/M50 traveling at 47.0 mph and above. The penetration ratings include P1 for less than or equal to 1 meter (3.3 ft.), P2 for 1.10 to 7 m (3.31 to 23.0 ft.), and P3 for 7.01 to 30 m (23.1 to 98.4 ft.). For example, an M50 P1 crash barrier is designed to stop a medium duty truck traveling 50 mph with a penetration distance of 3.3 feet or less.

In FIGS. 1 and 3, PVB 10 is positioned between a protected side 15 and a motor vehicle 11 approaching PVB 10 from an attack side 13. According to aspects of the disclosure, PVB 10 is configured to achieve a crash rating. In some embodiments, PVB 10 is configured to achieve a crash rating of M50 P1. In some embodiments, PVB 10 is configured to achieve a crash rating based upon a motor vehicle 11 impacting the barrier in a span of the beam between adjacent line posts or adjacent braces.

PVB 10 includes a continuous beam 12 positioned above ground level 17. For example, beam 12 may be supported approximately three feet off of ground level 17. PVB 10 may include one or more truss sections 14. In the illustrated examples, truss sections 14 are illustrated at terminal ends of a longitudinal length of continuous beam 12, however, truss sections 14 may be positioned within a longitudinal span of continuous beam 12. Beam 12 is formed of interconnected beam sections 16. Adjacent beams sections 16 are connected at joints 18. Joints 18 are pivoting connections that permit a degree of pivoting movement between adjacent beam sections 16 or a beam section and a post when beam 12 is impacted by a motor vehicle. Examples of pivot connections at joints 18 are illustrated in FIGS. 6A-6C, 7, and 10-15.

Posts, generally denoted by the numeral 22, are connected to beam 12, for example, to support beam 12 above ground level and to provide tension to mitigate lift of beam 12 in response to the impact of the motor vehicle. Posts 22 are metal members and may take various forms including I-beams, round or rectangular (e.g., square) members. Posts 22 may be arranged in a line post configuration, identified specifically with reference number 21, connected to beam 12 at a joint 18. Posts 22 may be arranged in an intermediate configuration, identified specifically with reference number 23, connected to beam 12 at an intermediate position in between joints 18. Some or all of posts 22 may be used to support an ornamental fence structure, e.g. a chain link section.

FIGS. 5A and 5B illustrate an exemplary beam section 16. Beam section 16 is a metal member, for example, an I-beam, for example, a wide flange beam or W-beam, extending between opposing terminal ends 26. Beam section 16 may be provided in different lengths. For example, in FIGS. 1 and 2, beam sections 16 may be forty feet and in FIGS. 3 and 4 beam sections 16 may be for example twenty or thirty feet in length. The dimensions described are non-limiting examples. A beam plate 28, e.g., connector, having a central aperture or hole 30 is attached at each terminal end 26. Two beam plates 28 are spaced apart vertically and attached at each terminal end 26 with the respective holes 30 coaxially aligned to dispose a pin and pivotally connect adjacent beam section and/or pivotally attached a beam section to a post.

FIGS. 5C and 5D illustrate another exemplary beam section 16. In this example, beam section 16 is referred to a female-male beam section 16. Female-male beam section 16 has a female terminal end 26′ on the left side carrying a female beam plate 28′. Exemplary female terminal end 26′ has and a groove or slot 68 to receive a beam plate 28 of an adjacent beam section 16 or to receive an independent connector plate, see, e.g. FIGS. 5E-5H. The second terminal end 26 of the female-male beam section is a male end carrying a beam plate 28. In this example, male beam plate 28 extends a greater distance away from terminal end 26 than female beam plate 28′ extends from terminal end 26′. In the illustrated example, female beam plate 28′ has a square hole 30 as opposed to a circular hole 30 formed in the male beam plate 28. In some embodiments, beam section 16 may be a female-female section having female beam plate(s) 28′ at both terminal ends or a male-male beam section illustrated for example in FIGS. 5A and 5B.

FIGS. 5E and 5F illustrate an exemplary independent connector plate 70 configured for pivotally connecting adjacent beam sections for example at a post such as illustrated in FIG. 6A. In this example, connector 70 is a generally metal planar member having two holes 30 spaced apart and located on opposite sides of the planar connector plate 70.

FIGS. 5G and 5H illustrate an exemplary connector 70 configured for pivotally connecting a beam section to a post such as illustrated in FIG. 6B. In this embodiment, connector 70 is generally T-shaped having a first planar member 72 and a second planar member 74 extending in different planes perpendicular to one another. A hole 30 is formed through second planar member 74. With reference to FIG. 6B, in use the first planar member 72 extends in a vertical plane for connection with post 21, e.g., a web of the post, and the second planar member 74 extends in a horizontal plane away from post 21 with hole 30 oriented vertically for accepting a pin.

FIG. 6A illustrates an example of adjacent beam sections 16 pivotally connected to each other at a line post 21. With additional reference to FIGS. 5E and 5F, connector 70 is connected to line post 21 with vertical holes 30 in connector 70 positioned on opposite sides of line post 21. For example, connector 70 is position in a web 76 of line post 21 with one hole 30 positioned on the left side of post 21 and the other hole 30 positioned on the right side of post 21. Left beam section 16 is positioned with hole 30 of beam plate 28 coaxial with one of the vertical holes 30 in connector 70 and right beam section 16 is positioned with hole 30 of beam plate 28 coaxial with the other one of the vertical holes 30 in connector 70. A pin 32 is positioned in coaxial holes 30 to create a pivoting connection at a joint 18, whereby adjacent beam sections 16 can pivot relative to one another and relative to line post 21 when beam 12 is impacted by a motor vehicle. In the illustrated example, pin 32 is in the form of a bolt with a securing nut. Another example of a pin 32 is illustrated in FIG. 22. Beam sections 16 each have a single beam plate 28 in FIG. 6A, however, beam sections 16 may have a two vertically spaced apart beam plates 28 as illustrated in FIGS. 5A and 5B.

FIG. 6B illustrates an example of a beam section 16 pivotally connected to a post 21 at a joint 18. With reference to FIGS. 5G and 5H, a connector 70 is attached to line post 21. For example, vertical member 72 of connector 70 is located on a first side of a center web 76 of post 21 with horizontal member 74 extending through center web 76 to a second side of post 21. Beam plate 28 of beam section 16 is positioned with connector 70 whereby a pin 32 pivotally attaches beam section 16 to post 21 at joint 18. In this example, a truss beam 62 is also attached at joint 18.

FIG. 6C illustrates another example of a pivotal connection of adjacent beam sections 16 via a joint 18 at a line post 21. Beam plate 28, e.g. male beam plate 28, extends from beam section 16 on the left of post 21 through web 76 to the right side of post 21. Beam plate 28′ of the right beam section 16 is positioned above beam plate 28 with their vertical holes coaxially aligned. A pin 32 is positioned in beam plates 28, 28′ pivotally connecting adjacent beam sections 16 at joint 18.

With reference, in particular to FIGS. 7-18, some embodiments of PVB 10 include braces 20 attached to beam 12. Braces 20 are located on the protected side and have a first end attached to beam 12 and a second end secured in a foundation 24, whereby the foundation and the brace form two adjacent sides of a vertex having an acute angle. The brace and the foundation form a sled to absorb or counter the impact force of the vehicle 11. Braces 20 may be connected to beam 12 at joints 18 (see, e.g., FIGS. 7 and 10) and/or connected to beam 12 at intermediate positions between the joints 18 (see, e.g., FIG. 16). Although braces 20 are illustrated in FIGS. 1 to 4 as being located with posts 22, the braces may be located separately from a post.

Foundation 24 is concrete and may be a shallow or a deep foundation. A concrete foundation having a depth, for example, of about twenty inches or less, may be considered a shallow foundation. Concrete foundation 24 may be about eighteen inches or less. Concrete foundation 24 may be about twelve inches or less. Concrete foundation 24 may be about six inches or less. Concrete foundation 24 may extend the length of beam 12 as shown for example in FIGS. 3 and 4 or concrete foundation 24 may be provided only at selected locations, such as at line posts 21 and/or braces 20 as illustrated in FIGS. 1 and 2.

FIG. 7 illustrates an example of a brace 20 that may be connected to beam 12 at a joint 18. With reference also to FIGS. 8A and 8B, brace 20 is, for example, a metal member extending from a first end 40 to a second end 42. First end 40 is connected to adjacent beam sections 16 via pivot pin 32 and second end 42 is disposed in foundation 24. A non-limiting example of a pivot pin 32 is illustrated in FIG. 22. Brace 20 may be constructed for example of an I-beam type member, e.g., W-beam. In this example, foundation 24 is a shallow concrete foundation extending for example about 18 inches or less below the ground level. In some embodiments, foundation 24 is a shallow concrete foundation extending for example about 12 inches or less below the ground level.

In this example, first end 40 is a rectangular shaped member extending horizontally relative to ground level and having a vertical hole 41 through which a tail end of pivot pin 32 is disposed, and a cross-hole 43 that may be aligned with a cross-hole 38 in pivot pin 32 (see, FIG. 22). Beam plates 28 of adjacent beam sections 16 overlap with holes 30 of beam plates 28 (FIG. 5B) coaxially aligned and positioned atop first end 40 of brace 20. Pivot pin 32 is disposed in coaxial holes 30 of beam plates 28 and vertical hole 41 providing a pivoting connection between adjacent beam sections 16 and brace 20. In this configuration, brace 20 in combination with the foundation 24 forms a sled to absorb the force of the impact of the motor vehicle from the attack side. Foundation 24 and brace 20 form two adjacent sides of a vertex having an acute angle 7.

In FIG. 7, a vertical post 22 in a line post 21 configuration is connected with brace 20 and beam 12 at joint 18. Vertical post 22 is a metal member having a bottom end 25 located in foundation 24. In the example of FIG. 7, posts 22 are positioned on the attack side relative to beam 12.
