In addition to the fixed structures, the event technology also includes the so-called “temporary structures”. These mobile structures are repeatedly erected and dismantled at various locations for a limited period of time. They are typically used at festivals and open-air events.
High safety requirements also apply to these buildings. The personnel that builds such structures must be educated and well trained. The riggers (rigg = rigging) usually erect such structures from stable truss systems, which are additionally anchored with ropes so that they can withstand wind and rain.
In order not to damage such a construction by introducing loads into the ceiling construction or even causing it to collapse, the load is monitored there at relevant nodes. The same applies to the ceilings of exhibition halls.
