New Case Study - Lidl Headquarters
18/09/2019
Location: Heilbronn, Germany Market: Fa?ades & Cladding Product: Type A Girder Clamps Project Value: ?238 million Main Contractor: Leonhard Weiss GmbH & Co KG Specialist Installer: Colt International
Project Background German discount supermarket chain, Lidl, has built a brand new headquarters on a 4.6ha area with a gross floor area of 130,000m2 in Heilbronn, Germany. The project involved the construction of an office building, meeting rooms, a reception facility, cafeteria, underground parking facilities, fitness centre, logistics facilities and outdoor parking facilities.
Client Requirement Part of the development included a requirement for a fa?ade sun protection cladding system for the multi-storey staff car park. Main contractor Leonhard Weiss sub-contracted this building element to Colt International, a specialist cladding designer and installer. The challenge was to find a suitable method of connecting the cladding system to the steel structure on the car park, and one that was easy to install.
Design Solution The engineers at Colt International designed a T-shaped steel bracket with an end plate incorporating four pre-drilled holes. Lindapter Type A Girder Clamps with M12 bolts were selected for use in the end plate connection to achieve the required tensile resistance and safe working load.
A hot dip galvanised (HDG) finish was also specified for the Girder Clamps to provide a high level of corrosion protection. The decision to use Lindapter Type A Girder Clamps was influenced by independent technical accreditations, which include the CE mark (ETA-13/0300), T?V and Lloyd's Register approvals.
Installation Secondary steel sections were fixed onto the existing concrete fa?ade in preparation for the T-shaped brackets to be installed. The brackets were connected to the steel sections using Lindapter Type A Girder Clamps through the end plates in a four-bolt configuration. Installation was straightforward and efficient as each bolt is simply inserted into the pre-drilled holes with the Type A on one end and nut on the other.
The recessed top of the clamp holds the bolt captive while the nut is tightened with a torque wrench to the recommended tightening torque. This arrangement provided the necessary standoff distance between the original structure and allowed the large cladding panels to be attached to the other end of the T-shaped brackets and complete the installation.
Result Lindapter Type A Girder Clamps provided a drilling and weld free connection at the project site that was straightforward and efficient to install. The clamps are fully adjustable which gave the contractor the ability during installation to manoeuvre the brackets into their final positions before fully tightening them.
Type A Benefits ? Recessed top holds the bolt captive while the nut is tightened ? Fully adjustable onsite to provide an straightforward on-site installation ? Supports as much as 78.8kN tensile in four-bolt configuration ? HDG finish offers a economical and low maintenance solution ? CE Mark (ETA-13/0300), T?V and Lloyd's Register approvals
