  • Median barriers which typically are relatively heavy devices that are frequently utilized for separating lanes of traffic from other lanes of traffic, construction work, etc.
  • the barriers typically must be sufficiently heavy such that, if accidentally contacted by a moving vehicle, they will prevent the moving vehicle from leaving its lane, thereby protecting construction workers, pedestrians, and/or other lanes of traffic on the other side of the median barrier.
  • Pre-cast reinforced concrete can be used to form median barriers. Yet to be most effective, there is a need to ensure that vehicles generally cannot pass through or substantially move a median barrier and thereby create a hazard to the adjacent lane of traffic, constructions workers, pedestrians, etc.
  • Median barriers can have certain resistance to movement caused by the weight of the barrier and the static coefficient of friction between the lower surface of the barrier and the roadway and/or other surface upon which the barrier is located. Because this coefficient of friction is generally fixed, the resistance to lateral movement is generally proportional to the weight of the barrier.
  • temporary barriers are often constructed with a length on the order of 12 feet, although longer or shorter barriers can be provided if the need arises (if, for example, it were necessary to have barriers around a very sharp curve, shorter barriers might permit the outer edge of the curve to be lined with barriers without the barriers intruding on the roadway).
  • Unfortunately as a barrier becomes smaller, its weight typically becomes less and, thus, its resistance to lateral movement becomes less. This can create challenges when a need arises for both a resistance to impact-generated movement and a non-linear grouping of barriers.
  • FIG. IB is a side view of an exemplary embodiment of a precast concrete barrier 10, showing longitudinally-extending top face 61, longitudinally-extending bottom face 62, end face 63, and end face 64.
  • FIG. 1A is a side view of an exemplary female interlocking structure 14 on one end of barrier 10, and showing longitudinally-extending side faces 65 and 66.
  • FIG. 1C is an end view of the other end of the barrier in FIG. IB showing an exemplary male interlocking structure 12 located thereon. Depicted in phantom lines are an exemplary connection structure for interconnecting the male interlocking structure 12 with the female interlocking structure 14 internal to barrier 10.
  • Barrier 10 can be constructed of reinforced concrete having a minimum
  • Reinforcement in barrier 10 can conform to ASTM A615, Grade 60.
  • the standard length for an exemplary barrier can be approximately 12 feet with the male portion protruding from the end of the barrier by approximately 1-7/8 (1.875) inches.
  • the width of the body of the exemplary barrier shown in FIGS. 1A and 1C can be approximately 24 inches and the height can be approximately 32 inches.
  • the body can be cast directly and/or in multiple units. For example, if a length less than approximately 12 feet be desirable, such length can be cast directly, and if a section longer than approximately 12 feet be needed, it can be cast as one unit, or as two or more units.
  • exemplary female interlocking structure 14 with a respective exemplary barrier 10 is shown in FIG. 4.
  • either the male end of an elevated leftmost barrier or the female end of an elevated right-hand barrier can be lowered vertically so as to interengage the web 20 and flange 22 of male interlocking structure 12 with the slot 30 and tube 26 of female interlocking structure 14.
  • This gap can permit one barrier to be canted with respect to another so as to permit a curve in a line of barriers without disengaging the interlocking portions of the barriers.
  • the barriers can continue to form a structural interconnection between adjacent barriers when forming a curve or other non-linear pattern along a roadway, median, etc.
  • This spacing also can permit barriers to be interengaged and/or interlocked when there is a vertical displacement, i.e., the line of barriers begins to go up and/or over a hill and/or otherwise encounters a change in grade and/or elevation.

  • interconnecting reinforcing bars 40 and/or 42 can be welded to anchor bars 24 and 28 that can be connected to male interlocking structure 12 and female interlocking structure 14, respectively.
  • anchor bars 24 and 28 can be connected to male interlocking structure 12 and female interlocking structure 14, respectively.
  • interconnecting rebar 40 and/or 42 merely can be wired to be substantially adjacent corresponding anchor bars 24 and/or 28 as shown in the phantom lines of FIGS. 1A and IB. This can facilitate precise alignment of male interlocking structure 12 and/or female interlocking structure 14 while the concrete is poured and/or cured.
  • interconnecting reinforcing bars 40 and/or 42 coextend with anchor rods 24 and/or 28 of male interlocking structure 12 and/or female interlocking structure 14 can be equal to approximately 40 diameters of the larger reinforcing bar, which can provide substantially the same structural strength as welding the bars together.
