Abstract
A stand-alone, roadway barrier includes: an internal structural framework (5, 7, 9) which provides the barrier 5 with rigidity for resisting collapse of the barrier in response to impact of a vehicle, panels (13) mounted to opposite sides of the structural framework for deflecting vehicles on impact with the barrier; and ballast (33) for contributing to the weight of the barrier. 10424456_1 (GHMatters) P93905.AU.229/06/18
Description
The present invention relates particularly, although by no means exclusively, to a stand-alone, selfsupporting, lightweight and readily portable metal (which term includes metal alloy) roadway barrier.
Known roadway barriers include:
(a) barriers made from concrete that rely on the weight of the concrete to function as barriers and typically weigh 1,000 kg per meter of the length of the barrier;
(b) barriers that comprise shells made from plastics materials that are adapted to be filled with water and rely on the weight of the water to function as barriers and typically weigh at least 300 kg per meter of the length of the barrier; and (c) barriers made from steel which also rely on the weight of the barriers to function as barriers and weigh at least 200 kg per meter of the length of the barrier and, in many instances are fixed to the ground.
Whilst the above-described barriers function effectively as barriers, principally due to the substantial weights thereof, the substantial weights of the concrete barriers and the steel barriers present significant transportation difficulties, and the need to fill water into and thereafter empty water from the plastics materials shell barriers presents significant handling issues and increases installation times considerably. In addition, concrete barriers and the water-filled barriers tend to crack when impacted by

- 2 vehicles and lose functionality as a consequence and invariably cannot be used as barriers after a vehicle impact. Moreover, the construction of these barriers, particularly the concrete barriers and the steel barriers, 5 means that the barriers have no give on impact of a vehicle. A certain amount of resilience of a barrier on vehicle impact is helpful.
There is a need for a lightweight barrier that 10 functions effectively as a barrier and can be readily be lifted into and from required roadway locations and is immediately functional as a barrier when lifted into position.
The above description of prior art barriers is not to be taken as an admission of the common general knowledge in Australia or elsewhere.
The present invention provides a stand-alone, self-supporting, lightweight, portable roadway barrier that includes :
1. A stand-alone, self-supporting, lightweight, portable roadway barrier that includes:
(a) an internal structural framework for resisting collapse of the barrier in response to impact of a vehicle, the framework including interconnected steel framework members, the framework members including (i) upright members at opposite 30 ends of the barrier and at least one upright member positioned between the upright end members, the upright members being in the form of plates extending perpendicular to the length of the barrier across the width of the barrier, the upright members dividing the barrier into spaces between the upright members along

- 3 the length of the barrier, and (ii) at least one longitudinal member extending along on the length of the barrier and connected to each of the upright members;
(b) steel panels mounted to opposite sides of the structural framework for deflecting vehicles on impact with the barrier, each side panel including a series of lengthwise extending corrugations that define panel ribs; and (c) ballast in the form of blocks of concrete or other solid material positioned in the spaces separating the upright members of the structural framework.
The purpose of the internal structural framework of the above-described barrier is to provide sufficient rigidity for resisting collapse of the barrier in response to vehicle impact. Specifically, the interconnected arrangement of upright and longitudinal framework members is provided to give the framework sufficient rigidity for resisting direct collapse of the barrier in the regions of vehicle impact and from uncontrolled twisting of the barrier around a longitudinal barrier axis. The upright members of the structural framework also act as supports for the side panels.
Typically, the internal structural framework provides at least 80%, more typically at least 90%, of the 30 rigidity for resisting collapse of the barrier in response to vehicle impact.
The principal purpose of the side panels of the above-described barrier is to deflect a vehicle on impact of the vehicle against the barrier. Accordingly, it is not essential that the side panels make a substantial contribution to the rigidity of the barrier and this makes
10424456_l (GHMatters) P93905. AU .229/06/18
2018100904 29 Jun 2018
- 4 it possible to minimise the weight of the side panels.
Typically, the side panels contribute no more than 30% of the rigidity of the barrier.
The principal purpose of the ballast is to provide weight to resist shunting action on vehicle impact that would move the barrier significantly from a preferred position on the ground.
The structural framework may include a central upright member positioned midway between the upright end members .
The central upright member may include an opening that can receive a crane hook to facilitate lifting of the barrier.
The steel plates may include mounting sections to which the side panels are connected.
The longitudinal member or at least one of the longitudinal members may extend along the length of the barrier and be connected at opposite ends to the upright end members and be connected to the or each upright member 2 5 located between the upright end members .
The longitudinal member or the lower longitudinal member when there are two or more longitudinal members may be positioned at a height that is 30 at or higher than 25% of the height of the barrier.
The longitudinal member or the lower longitudinal member when there are two or more longitudinal members may be positioned at a height that is 35 at or higher than 50% of the height of the barrier.

- 5 The longitudinal member or the lower longitudinal member when there are two or more longitudinal members may be positioned at a height that is at or above a centre of gravity of a typical vehicle.
The applicant has found that the location of the longitudinal member or the lower longitudinal member when there are two or more longitudinal members as described in the three preceding paragraphs is preferable from the 10 viewpoint of the overall rigidity of the barrier and in terms of minimising the possibility of lengthwise twisting of the barrier in response to vehicle impact.
The longitudinal member or at least one of the longitudinal members may be in the form of steel plates.
The side panels may be made from steel strip that has been mechanically worked, such as by rollforming, into a required profile. The required profile 20 may be a profile that facilitates deflecting vehicles on impact.
The side panels on opposite sides of the barrier may diverge outwardly from each other when viewed from the 25 ends of the barrier.
The ballast may be in a lower section of the barrier.
The height of the ballast may be lower than the height of the typical vehicle impact with the barrier. This is an important feature so as to ensure that the structural framework and the side plates of the barrier respond to the vehicle impact by absorbing impact energy and deflecting impact, while the ballast resists shunting movement of the barrier. This arrangement of the

- 6 components of the barrier provides an effective response to vehicle impact.
The ballast may be connected to the internal structural framework or to the side panels.
The ballast may include a support element for mounting the ballast to the internal structural framework or to the side panels.
The ballast may include a body, such as a block of a suitable ballast material, and a support element for mounting the ballast to the internal structural framework or to the side panels.
The support element may be in the form of a bracket, such as an angle iron bracket, that is bolted or otherwise fastened to the body of the ballast and is adapted to cooperate with the internal structural framework or to the side panels to mount the ballast to the internal structural framework or to the side panels.
The ballast may include a plurality of blocks of a suitable ballast material positioned in spaces separating the upright end members and the upright member or members positioned between the upright end members.
The ballast may be made from concrete or any other suitable material.

The present invention is described further by way of example with reference to the accompanying drawing, of which:
Figure 1 is a perspective view of one embodiment of a barrier in accordance with the present invention;
Figure 2 is a perspective view of the barrier shown in Figure 1 with the side panels and the ballast removed to show the internal structural framework of the barrier;
Figure 3 is an exploded perspective view of the barrier shown in Figure 1 which shows the blocks of ballast;
Figures 4 and 5 are respective side and end views of one of the ballast blocks and the brackets for connecting the ballast block to the internal structural framework of the barrier.
The barrier 3 shown in the Figures includes an internal structural framework of:
(a) upright support plates 5 at opposite ends of the barrier;
(b) three upright support plates 7 at spaced intervals along the length of the barrier between the end plates 5 and arranged to extend across the width of the barrier; and (c) a longitudinal support member 9 (best seen in Figure 2) in the form of a horizontally

- 9 disposed flat plate connected at opposite ends to the upright end plates 5 and to the internal upright plates 7;
The structural framework is made from steel.
More particularly, the upright support plates 5, 7 and the longitudinal support member 9 are steel plates of any suitable gauge.
The height of the longitudinal support member 9 is selected to be at or higher than 25%, more preferably higher than 50%, more preferably higher than 60%, and typically higher than 75%, of the height of the barrier 3. Typically, the selection is based the height of or greater 15 than the height of a centre of gravity of a typical vehicle.
The barrier 3 further includes side panels 13 that extend along the length of the barrier on opposite 20 sides thereof and are connected to the upright support plates 5, 7 of the structural framework by bolts and or by welding the components together or by any other suitable means .
Each side panel 13 is made form steel and is corrugated and includes three parallel crests and two parallel troughs between the crests. It can be appreciated that the side panels 13 may be any suitable profile to facilitate deflecting vehicles on impact with 3 0 the barrier 3.
The side edges of the upper sections of the upright support plates 5, 7 have a similar corrugated profile to that of the side panels 13. In addition, the 35 side edges of the upright support plates 5, 7 diverge outwardly to form a Christmas tree formation when viewed from the ends of the barrier. Consequently, the side

2018100904 29 Jun 2018
- 10 panels 13, as a consequence of being connected to the upright support plates 5, 7, diverge outwardly.
Each upright end plate 5 comprises an assembly which enables a plurality of the barriers 3 arranged endto-end to be hinged together to form a continuous line of the barriers, with the barriers in end-to-end relationship. Each hinge assembly comprises four horizontally disposed and vertically spaced-apart hinge 10 plates 17 having aligned openings 21. The positions of the hinge plates 17 are selected so that the hinge plates 17 at one end of one barrier 3 are above or below the hinge plates at the other end of another barrier 3 when the barriers 3 are positioned end-to-end and the openings 15 of the two sets of hinge plates 17 are aligned.
Consequently, a hinge pin 33 (Figure 3) can be inserted through the aligned openings 21 to hinge the two barriers together.
The barrier 3 further includes 4 blocks 31 of ballast (see Figure 3).
The ballast blocks 31 are made from concrete or any other suitable material. The principal function of 25 the ballast blocks 31 is to provide mass to resist shunting action on vehicle impact that would move the barrier significantly from a preferred position on the ground. The ballast blocks 31 make it possible for the barrier 3 to be used as a free-standing, self-supporting 30 unit that can remain substantially in position on vehicle impact.
The ballast blocks 31 are formed to be located in a lower section of the barrier 3. The height of the ballast blocks 31 is selected to be lower than the height of the typical vehicle impact with the barrier so as to ensure that the structural framework 5, 7, 9 and the side

2018100904 29 Jun 2018
- 11 panels 13 of the barrier 3 respond to the vehicle impact by absorbing impact energy and deflecting impact, while the ballast resists shunting movement of the barrier 3.
This arrangement of the components of the barrier 3 provides an effective response to vehicle impact.
The ballast blocks 31 are located in the spaces separating the upright end members 5 and the upright members 7 positioned between the upright end members 5 and 10 are mounted to the side panels 13. With reference to Figures 3 and 4, the ballast blocks 31 include support elements in the form of a pair of forward and rearward angle iron brackets 35 that are bolted to the ballast blocks 31. Figure 4 shows a single bolt 37 used to secure 15 a bracket 35 to a ballast block 31. In other embodiments, or more bolts or other suitable fasteners may be used to secure a bracket 35 to ballast block 31. The brackets 35 have downturned ends that facilitate locating the ballast blocks 31 to the barrier 3, with the bracket ends resting 20 on inwardly-turned sections of corrugations of the side panels 13 and thereby mounted to the side panels 13. With this arrangement, the ballast blocks 31 are not fixed to the side panels 13. The weight of the ballast blocks 31 keeps the blocks in position. It can be appreciated the ballast blocks may be fixed to the side panels 13, for example by bolts or other suitable fasteners (not shown) passing through openings (not shown) in the brackets 35.
In use, the barrier can be conveniently transported from a storage location to a roadside location and then lifted into position as a functional barrier.
