Large spans for a logistics hubQuick facts:
- Double-deck mezzanine flooring
- Portalised construction
- Optimised column grid and huge spans; Profielnorms’ core strength
- Mezzanine surface: 31,000m2
- Fire enclosures around stair towers
The mezzanine floors were part of a major, new central logistic hub for our customer. Goods of the customer a mainly large packages, therefore wide spans in the steelwork are necessary to prevent the customer from a lot of obstacles, and to maintain wide driveways. A lot of free space under the mezzanine gives directly two other challenges; no blocking cross bracings for the obvious reason and a huge point load on the concrete floor.
Together with the consulting party in between, we came up with a sequence of nine, seven, seven metre span in main beam direction and six metre spans in secondary beam direction. This uneven column grid was a hundred percent match with the building column lay out and the required driveways.
