To further enhance a building's room climate, acoustic performance
and thermal performance, an AERCON roof panel system is the best solution to attain all of
these characteristics. AERCON roof panels can be installed on a slope or horizontal.
The thermal effects, within the building, from the summer and winter temperatures are
minimized. Similar to AERCON floor panels, AERCON roof panels weigh less than other concrete
roof systems. Therefore, a reduction in the size and weight of the building foundation
system may be possible.
Another distinct advantage of using AERCON roof panels is the speed
of installation. A roof area up to 40 ft2 is easily installed with one crane lift
utilizing a welltrained erection crew. The fireresistant characteristics for AERCON
are exceptional.
Fabrication
Roof 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 nominmal panel thickness of 8", 10" or 12" is available depending on the loading
and span requirements.
Panel System
Roof 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 roof panels depends on the required
span and loads.
Also, the panel thickness may be influenced by the thermal or
acoustical insulation requirements in conjunction with the required dead and live 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 roof panel
- 39 pcf for AC4
- 49 pcf for AC6
- Dead Loads
- Roofing 15 psf
- Ceiling/Mech. 10 psf
- Live Loads
- Roof 20 psf
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 roof 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 roof panels, due to the total
load, is L/180. The allowable deflection for the live load is L/240.
Support
The length of bearing required for AERCON roof 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.
Roof Shapes
Traditional flat or sloped roofs are possible with AERCON roof
panels. The roof slope for drainage can be achieved by sloping the support
framing of the underlying structure or by providing a layer of tapered insulation
(the traditional method) on the roof panels.
