Developer: Local Authority Contractor:
Coulsons Building Group, Cambs Supplier:
Project Completion: Autumn 2016
New school building construction requiring the fixing of internal timber frame to external steel frame. Timber members had to be fixed tight against each other with no access to head once installed.
Contractor was unable to source M10 x230mm coach bolts and Joyner Bolts were recommended as an alternative by supplier.
360 M10x230mm Joyner Bolts used.
Conclusion & Feedback
Use of Joyner Bolts was proved to be both cost effective and time efficient.
Contractor feedback highlighted that the captive head allowed Joyner Bolts to be affixed in tight spaces without need to access second side, saving time whilst guaranteeing quality of joints.
Flat head also allowed immediate cover without additional countersinking, saving time and ensuring finish quality for next stage.
