Problem and requirements

A roof renovation meant that several movable hall tents were required on the roof of a building. Due to the location, it was not possible to employ standard anchoring techniques, and in addition, there was the problem of the increased wind loads.

Solution

Several movable tents were erected in succession on rails.

Special-purpose concrete blocks were employed for external ballast. Additional belt braces, which could be released rapidly, were attached to the roof substructure.
