Problems solved by technology

[0009] Although the above-mentioned guardrail has effectively played the role of a guardrail, it is mainly due to its large weight, which brings great difficulties to transportation.
[0010] In addition, the need to fill the plastic material housing rails with water and then to drain the water from the plastic material housing rails presents a significant handling problem while adding significantly to installation time
[0011] In addition, concrete barriers and water-filled barriers tend to crack when subjected to a vehicle impact and thus lose their functionality, and are always no longer usable as barriers after a vehicle impact
[0012] Additionally, the construction of these barriers, especially concrete and steel barriers, means that the barriers are not "resilient" to the impact of a vehicle

Embodiment Construction

[0104] The embodiment of the elongated guardrail 3 shown in the figures is typically 5.8m long, 900mm high, 450mm wide at the bottom, 200mm wide at the top, and weighs less than 2.6 tonnes, comprising:

[0105] (a) a housing, located in an elongated lower portion of the guardrail 3, said housing defining a cavity 11 (see figure 2 ), when manufacturing the guardrail 3, the cavity 11 receives and holds a pourable, self-leveling, solidifiable ballast substance;

[0106] (b) a superstructure element 13 extending along the length of the guardrail,

[0107] (c) Solid block 15 of ballast material in cavity 11 formed by pourable curable ballast material which partially fills cavity 11 - see figure 2 and 3 ;and

[0108] (d) a plurality of complementary connectors 17, such as those described in the applicant's Australian Patent Application 2015203840, at the ends of the guardrails 3, which allow a plurality of guardrails 3 to be connected together in end-to-end relationship.

Abstract

An elongate barrier (3) comprises an outer shell in an elongate lower section of the barrier that defines a cavity (11) that receives and contains a pourable settable ballast material when the barrier is being manufactured. The barrier also comprises a solid block (15) of a ballast material in the cavity formed from the pourable settable ballast material.

Description

technical field [0001] The invention relates to a guardrail adapted to divide an area into separate areas. [0002] In particular, although not exclusively, the invention relates to a guardrail suitable for use in a variety of end applications including, for example, use on roads, for separating a vehicle from other vehicles, separating a vehicle from a work area, Allows safe work in the work zone and separates vehicles from pedestrians. [0003] In particular, although not exclusively, the present invention relates to a self-contained, self-supporting, lightweight and easily transportable metal (the term includes metal alloys) guardrails. [0004] The invention also relates to a method of manufacturing a guardrail. Background technique [0005] Known road barriers include: [0006] (a) guardrails made of concrete, which rely on the weight of the concrete to function as a guardrail, normally weighing 700 kg / m over the length of the guardrail; [0007] (b) a guardrail com...
