Construction Period 08/2013 - 02/2014
During the renovation of the Public Baths in 2013-2014, a reduction to
the massive noise level in the indoor swimming area was requested. The
old wooden roof structure needed to be kept, but it could stand only small
additional loads. The solution of
a membrane covering with acoustics
sails
in Silent Protect MA 680 was presented as an alternative to the
appropriate acoustic plates. The client decided on the sails because of the
installation and aesthetic advantages. After surveying the existing structure
it was build-up detailed in SCIA Engineer with
Structure-, 3D-Free-
Modelling- and Drawing tools
. The environment with the appropriate part
of the site structure was exported as DWG/DXF to the Easy software to
design the required form for the membrane. The results of the membrane
calculations were imported back in SCIA Engineer to design the support
frame structure, anchors and edge/corner details. The fully detailed
structure was developed into one 3D-Model in order that each distance
and height could be considered precisely in 3D-Space. All the overviews,
elevation, execution and detail drawings were processed and created in
SCIA Engineer with appropriate Modelling and Drawing Tools. The most
difficult challenge was to find the
right level of pretension
to keep the
sail even enough and at the same time to limit the anchors reactions on
wooden roof beams. The
limits of the deformations
due to pretensioning
during erection have to be considered too.
