Grasso RC6 - Concrete Structure

A1.3.1 Concrete structure
The concrete block for compressor and motor or
compressor package should have a profile as
illustrated in fig. A1.2 and made according to the
following recommendations:
• The concrete block should be set on firm
footings or on a floor capable of carrying the
weight of the concrete block and capable to
absorb the free forces and gas forces of the
compressor during operation. The ground under
the concrete block should be horizontal and flat
(refer to fig. A1.2).
• The top surface of the block should be level and
even.
• There should be sufficient free space around the
block to install corkboard (or similar).
• The block should be provided with anchor bolt
recesses or holes (fig A1.3.) according to the
anchor bolt spacing as per package lay out
drawing.
It is recommended to consult a concrete specialist/
constructor for the following items:
• The compounding of the concrete with/without
reinforcement.
• The exact grouting depth (dependent on the
soil conditions).
• Installing foundation onto an existing floor, with
sealing corkboard or vibration isolators.
