C & E Scaffolding - Introducing Jacktie – an advanced tool in securing to cladded steelwork
The need to secure scaffold to steel purlins in places where
access is only available from one side and there is not enough
room for a buttress to be erected has led to the innovation of
Ideally suited to the access and scaffolding industry, the 25mm Jacktie provides a method of securing to cladded steelwork, hollow section steel structures or RSJs where access is limited. The tool can easily be used with ring bolts to tie the scaffolding to the building, and must be secured to the steel purlin.
Jacktie offers a number of key benefits, not least of all in safety, as it can only be tightened or removed with the appropriate key. Other benefits include:
The elimination of the need to erect a buttress to stabilise scaffolding, potentially saving pounds on labour and material costs
A neat and clean finish on the cladding as the 25mm hole can be covered with a plug
It is recoverable and so can be used over and over again.
Mike Cheetham, Director of C & E Scaffolding said, “I came up with the idea of the Jacktie initially as a solution to securing scaffold to steel purlins in places where access is only available from one side and there is not enough room for a buttress to be erected, for example buildings close to railway embankments. Currently, most scaffold companies will know that the only way to tie the scaffolding to the building would be to have a sheeting company cut a large enough hole in the cladding to allow the scaffolding to be tied to the steelwork using conventional tube and fittings.
Once the scaffolding is taken down, the building is then left with a large unsightly patch in the cladding which has to be made good by the cladding company. By using the Jacktie, you only need to drill a 25mm hole which can be covered with a translucent or colour coded plug on dismantle of the scaffolding, which is far more pleasing to the eye than a large patch in the cladding.”
The Jacktie is installed in six easy steps, starting with drilling the hole through the cladding to the steel purlin behind. Once in place, a key is used to engage the locking pins of the Jacktie, which is then pulled back, allowing it to lock in place behind the steelwork, then the wheel collar is hand-tightened up to the face of the cladding. A 16mm ring bolt can then be screwed into the front of the Jacktie and scaffold tube can be attached through the ring bolt to tie the scaffolding to the building using the standard procedure for physical ties as detailed in BS5973.
Designed and tested to the standards of BS5973 section 2 paragraph 9.7.1 (e), the Jacktie has a safety factor in excess of 5:1. Measuring 25mm in diameter and 190mm in length, it has an inwards/outwards capacity of 6.25kn.
Other sizes of the Jacktie are currently being researched and developed which will make it suitable for many other trades and uses.
