Halfen Scores A First At The New Wembley
Stadium
World-first in fixing technology at the new Wembley Stadium, where 26 concrete cores of up to 40 m in height have been slip-formed by a specialist contractor.
Halfen Reinforcement, in a joint-development with the PC Harrington Group, has achieved a world-first in fixing technology at the new Wembley Stadium, where 26 concrete cores of up to 40 m in height have been slip-formed by the specialist contractor On large-scale projects, continuous slip-forming of walls offers economies of construction, but necessitates that interconnecting landing joints are by-passed and connected later

Tune Into Halfen - For Vibration-Free Fixing
Halfen, the UK leading supplier of channel-based fixings for the building and construction industries, have the ready-made answer to new Control Of Vibration at Work Regulations.
At Wembley Stadium, project director PJ Harrington needed greater efficiencies in the construction of the cores, and was concerned that time saved by slip-forming the walls could be lost by the relatively slow process of constructing the many, large in-situ landings.
He elected, instead, to use precast landings, but still needed to apply a structural concrete topping in order that the structure behaved in a composite manner.
Mr Harrington enlisted Halfen's help and the solution quickly evolved in the form of a hybrid arrangement of Halfen's new 38/23 high load, toothed channels factory-supplied suspended from Kwikastrip units housing T16 bars at 100mm centres.
A shelf angle was subsequently secured back to the channels using Halfen's high load, toothed T-head bolts, and the Kwikastrip bars were then bent out and the precast landings bedded into position on the angle.
The structural topping poured onto the landings also filled the wall rebate created by the Kwikastrip casing and the hybrid joint was complete.
This fixing method obviated the need for post-drilling and setting anchors, avoiding not only health and safety problems including vibration white finger, but also the risk of drilling through main reinforcement.
Design-through-to-installation was achieved in record time, helping PC Harrington's programme for construction of the cores to redefine the term 'fast-track'. Request a free brochure from Halfen ...
