O’Reilly Brothers were the supplier of the precast concrete elements for Hilton Garden Inn Hotel Terminal 2, Heathrow Airport. This included pre-stressed hollow core slabs and walls. In total there were 1,100 walls panels produced at a total area if 14,000 m².
The traditional method to assemble precast wall panels onsite is to brace the outer walls which is extremely labour intensive and time consuming. Due to the sheer volume of walls to be assembled, a short assembly programme and high safety onsite the client required a more efficient method of wall assembly.
As the UK and Irish supplier of BT Innovation products, we felt that the BT Turnbuckle was the perfect solution allowing for fast, secure connection of precast walls. This system meant that wall connections could be secured up to 50% faster than traditional methods and removed the need for grouting. SDG along with our partner BT Innovation created the specific designs for the ensure that the cast in elements were sufficient to secure the panels and remove any potential over or under specification for the project saving time and reducing cost
The Turnbuckle can be used as part of an easy to use connection system – without additional materials and tools.
The BT Turnbuckle enables efficient and precise assembly and durable connections for precast concrete elements. By using BT Turnbuckle and corresponding connection materials, precast elements can be joined together without grouting.
SDG Construction Technology supplied 1200 turnbuckles to O’Reilly Brothers.
O’Reilly Brothers Richard Kowalski, Technical Director comments “BT Turnbuckle has made it possible to reduce the temporary bracing of walls to increase safety and shorten the assembly time of the outer walls.”
