A control barrier assembly comprising at least one pair of control barriers 10 10 arranged parallel to each other but in different planes, each control barrier having a planar barrier wall 12 12 and a support 14 and one or more cross-beams 20 removeably attachable to each control barrier to brace the pair and form a rigid arrangement. Preferably the end of the cross beam has a hook which engages with the panel, the hook having unequal ends (see Figure 3). Alternatively the ends of the beam may have a plug for engaging with a socket on the barrier, there may be an engagement mechanism for securing the plug in the socket. The plug may have flanges for engaging with the socket and a neck section (see Figure 6). The cross beam may be telescopic. |
