Not all examples may be highlighted, but the same principles can be used in other scenarios. In the absence of these instructions, below are a number of examples showing preferred practices and unsafe practices. Where the scaffolding manufacturer specifically provides documented instructions on the correct installation of tie bars, these instructions must be followed. Position of tie barsĪny tie bar should be installed so that a single distinct action, without a scaffolding plank sitting on top of the bar, cannot dislodge any one pin on the tie bar. This prevents accidental dislodgment of the tie bar. When installing platform brackets, make sure that they are interconnected with a tie bar and that the open side of the tie bar angle faces inwards, enabling the steel plank to sit in the angle.

The issue of inadvertent dislodgement of tie bars is not specifically discussed in the Queensland Scaffolding code of practice 2021 (PDF, 1.63 MB) (the code). Pins with the 45 degree bend are usually more effective at helping to prevent inadvertent dislodgement of the pin, particularly when the pin is inserted so that the end of the pin points back towards the scaffolding (refer Photographs 2 and 3). Pins with a 45 degree bend half way along the pin.The locating pins on tie bars are generally of two types: For example, a bouncing motion caused by an object falling down on the scaffolding deck or an inadvertent vertical or horizontal force should not be able to dislodge the tie bar. There have been a number of incidents in Queensland where tie bars have become inadvertently detached and workers have either fallen or been struck by a falling tie bar.Īny single inadvertent force should not be able to dislodge any part of the tie bar.

splaying) and to prevent planks becoming dislodged and falling.Īs well as preventing planks from falling, the tie bar should be designed and installed so that the risk of the tie bar becoming dislodged and falling is minimised.Īn example of a tie bar on a two-board hop-up bracket is shown in Photograph 1. Tie bars are provided on two and three board hop-up brackets to prevent the brackets rotating (i.e.
