Planning
instructions for for various load conditions, Granab Subfloor
Systems 3000 and 7000
The unique design of the Granab systems – with components
of non-organic materials, steel girders, dampening
elements and adjustment screws in various lengths –
permits installation in many different types of projects and
entails considerable benefits.
The dampening element, which provides progressive resilience,
makes the system an excellent choice for
floors in sports centres and other multi-purpose areas, for
example.
The specified load capacity, 4 tons/m2 at c/c 600, can be
significantly improved with tighter c/c spacing of
both girders and adjustment units.
Recommended c/c distances between floor girders (sections)
and support blocks, Systems 3000/7000:
| • |
Rooms in dwellings, hotels, hospital rooms
and staff
rooms, c/c distance, girders (sections), 600 mm. |
| • |
Assembly rooms such as classrooms, rooms in childcare
centres, lecture halls, office rooms, premises for
restaurants, cafes and dining halls, c/c distance, girders
(sections), 400 mm. |
| • |
Open areas in libraries, spaces with fixed seating
such
as in churches, theatres and cinemas, c/c distance,
girders
(sections), 400 mm. |
| • |
Spaces without fixed seating in churches, concert
halls,
theatres, cinemas, museums, exhibition halls, retail
areas
in department stores and shops, gyms, sports centres,
dancehalls, corridors in schools, etc., c/c distance
girders (sections), 300 mm. |
Load capacity
For girder spacing for homes, c/c distance 600 mm = 4 tons/m2
The point load capacity and distributed load of various floor
coverings installed on Granab systems are calculated according
to the specifications of the respective flooring manufacturers. |
