What
are Space Frames?
Space Frames represent the ultimate in aesthetics
& engineering efficiency in structural systems.
Behind its elegance and simplicity lies its
structural capacity to achieve extremely long
spans.
They are assembled from linear elements, so
arranged that the loads are transferred in three
dimensions. Broadly, a space frame often takes
the form of a flat or curved surface.
They are assembled using two factory-produced
components: connectors,such as CNC machined
spherical or cylindrical node connectors and
chord elements, such as rectangular or circular
hollow sections, assembled at the site using
relatively unskilled labor.
Why Space Frames?
-
Architecturally
elegant means of covering large column free
spaces with flexible work layout for variety
of applications.
-
Completely
pre-engineered and assembled at site using
prefabricated components to eliminate site
welding that results in uncertain quality.
-
Can be
installed over operating facilities with
least disturbance and downtime.
-
Light,
structurally efficient and use minimum of
materials to maximum structural
advantage, and hence cost-effective.
-
Savings
in foundation cost due to large column spacing.
-
Utilities
such as lightings & air-conditioning
ducts can be conveniently accommodated
in the space frame itself.
-
Floating
platforms can be hung from any joint for
flexibility during erection and mainten.
