There are a number of reasons for choosing autoclaved aerated
concrete floors. Consider the low weight, for instance. This influences the size and
weight of the foundation, since a traditional floor weighs three times as much as
its AERCON counterpart.
The fire-resistant characteristics for AERCON are exceptional.
Also, the AERCON floor panels have superior sound and thermal characteristics
inherent to AERCON material.
Another distinct advantage of using AERCON floor panels is
the speed of installation. A floor area up to 40 ft2 is easily installed with
one crane lift utilizing a well-trained erection crew.
Fabrication
Floor panels are supplied on the basis of Strength Class AC4
and AC6. The maximum panel length is 20'-0". The standard panel width is 2'-0" .
A nominal panel thickness of 8", 10" or 12" is available depending on the loading
and span requirements.
Panel System
Floor panels are tailor made. Their length, thickness and
reinforcement are determined based on the building requirements
and specifications. The standard panel width is 2'-0". See the Overview
Section for panel profile information.
Panel Cutting and Openings
All panels may be cut and may contain openings throughout
the panel. However, the size, location and type of cut or opening should be
coordinated with AERCON prior to the design phase to avoid any unnecessary
field modifications.
The reason for this is that every opening, notch or cut (round,
rectangular, diagonal) causes additional stress on the area around the potential
cut. Any additional reinforcement requirements can be taken into account during
the design and fabrication process.
Panel Thickness
The thickness of AERCON floor panels depends on the required
span and loads.
The following typical loads may be used for calculating the panel
thickness. However, all panels are designed based on the project requirements,
as specified by the Design Professional.
- Weight of the floor panel
- 39 pcf for AC4
- 49 pcf for AC6
- Dead Loads
- Flooring 5 psf
- Ceiling/Mech. 10 psf
- Partition 20 psf
- Live Loads
- 40 psf for residential
- 50 psf for offices
- 80 psf for corridors
- 100 psf for egress
For non-standard loads and related questions, consult an
AERCON Representative. Check all local jurisdictional requirements for any
additional or differing required design loads.
The graph below shows representative spans for a range of
live loads. This graph may be used for the preliminary determination of the thickness
required for a particular project. Since floor panels are uniquely designed for a project,
the maximum span for an individual panel may deviate from the graphical value.
Deflection
The allowable deflection of AERCON floor panels, due to
the total load, is L/240. The allowable deflection for the live load is L/360.
Support
The length of bearing required for AERCON floor panels is 21/2"
minimum.
Grouting
The key joints at adjacent panels are filled with cement grout
in order to provide a positive diaphragm shear transfer.
