Hollow Floor / Partial Access Systems
This type of system provides a service void into which the building’s services can be housed, whilst providing a continuous monolithic walk and work surface. Access to the services within the floor void is gained through a series of dedicated access hatches built into the floor during its construction.
There are two methods of creating the “hollow floor”. One system utilises load bearing inert calcium sulphate panels, generally 2400 x 600mm with a tongue and groove construction; this being a “dry” construction. The second method relies on a thinner sacrificial panel on to which an anhydrite floor screed is poured on to, typically described as a wet system.
Both of the systems described above rely on steel adjustable pedestal supports to create the service void and support the overall floor loadings. Gesutra GmbH manufactures comprehensive ranges of pedestals in M12, M16 and M20 format. With pedestal heights ranging from 23mm right through to pedestals at 1.8 metres high, you can be assured that there is solution for every eventuality.
The selection of the correct pedestal to be used depends upon the height of the service void and the load bearing requirements of the floor system. In certain circumstances lateral or load bearing stringer supports are introduced to offer additional integrity and performance.
