Secure
scaffold steel purlins
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
the Jacktie.
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.
