A modular barrier consists of a plurality of identical barrier sections. Each section (10) includes a base portion (12) surmounted by an upright portion (14). The upright portion has projections (16, 18) with substantially semicylindrical outer surfaces at its ends. Correspondingly shaped recesses (20, 22) are also provided. At a femal end, the base portion (12) includes a nose (28). The surface of the nose is a surface of rotation of the profile of the base portion (12). At the male end, the base portion (12) includes a correspondingly shaped cavity (30). The first and second projections (16, 18) and nose (28) are provided with bores (32, 34, 36). When the female end of the barrier section (10) is brought up to a male end of a similar section, the projections mate with one another and the nose (28) is received in the cavity (30) of the similar section. A hinge pin (not shown) may then be passed through the bores (32, 34) and (36). By means of this device, one barrier section can be articulated to the next and the joint between the two portions of adjacent barrier sections presents an essentially smooth profile irrespective of the angle between the two.
A modular crowd and traffic control barrier including:
A modular barrier according to any preceding claim in which the means for attaching each reinforcing strip to a respective barrier section comprises a tension member that passes through aligned apertures in the reinforcing strip and the barrier section.
A modular barrier according to any preceding claim in which the barrier sections are substantially identical.
A modular barrier according to any preceding claim in which, for each projection on one end of a barrier section, a corresponding recess is provided on the other end.
A modular barrier according to any preceding claim in which each projection of a barrier section is provided with a bore and, when the female end of the section is brought up to a male end of another such section so that the nose is accommodated in the cavity, the bores in the projections line up allowing a hinge pin to be passed through them to articulate the sections together.
A modular barrier according to any preceding claim and further comprising hinge pins, in which the projections on a female end of a first barrier section mate with the projections on a male end of another barrier section and a hinge pin passes through them and through the nose of the first barrier section, to articulate the sections together.
