Daktronics CH-1024H - Manual (Page 8)

2-2 Installation
These footing recommendations are based on an allowable soil bearing pressure of 300 psf
vertically and 300 psf/ft of depth horizontally. However, these recommendations are
suggestions only and each installation should be treated individually. Be sure that the
installation complies with local codes and is suitable for particular soil and wind conditions.
Daktronics assumes no responsibility for structures installed by others.
A note about beam nomenclature: For a typical beam, W6x16 for example, "W" stands for
"Wide-Flange Beam". The first number (6) is the approximate front to rear dimension of the
beam in inches. The second number (16) is the weight per foot in pounds. This numbering is
a standard in the steal industry. Widths are from 4.00 to 10.00 inches in the chart above.

Beam And Footing Selection
Reference Drawing: Footing and Beams......................................Drawing A-46451
The above contains recommendations for beams and footings. The distance in the first
column is from the ground to the bottom of the CH-1024H display, regardless if one or two
extra sections, such as an ad panel and/or message center, are added to the CH-1024H scoring
display. The second column is wind velocities that are likely to occur at the display location
in miles per hour.
The beams listed are W-section (wide flange) beams which provide maximum wind load
strength for the weight and cost of the beams. Decide how high you want your display and
what sort of wind it will be subject to. Read across the table to the appropriate column for
your display; these are the beams and footings that are recommended. Drawing A-46451
shows a typical installation of beams and footings.
The calculations for footing diameters and depths are based on the assumption that footings
are in undisturbed soils, not fill soils, with a lateral bearing capacity of 300 psf/ft of depth
horizontally. However, these recommendations are suggestions only and each installation
must comply with local codes and be suitable for the particular soil and wind conditions.
Daktronics recommends that W-section grade 36 steel be used for beam, and that 28-day
(strength 3000 psi) concrete be used for footings. Daktronics assumes no responsibility for
structures installed by others.
2.3 Display
Mounting
Reference Drawing: Mounting Instructions...................................Drawing A-38856
Drawing A-38856 shows the typical mounting for your display.
Note: The bolts that secure the display sections do not go through the beams, but run along
the sides of the beam, clamping the display to the beams.
A mounting kit with mounting angles and
2" hardware are provided to mount your display.
Position the display against the mounting beams and secure the bottom of the display to both
beams as shown. Next, secure the top of the display. Once mounting angles are attached, the
display may be slid up or down to the desired height. Once positioned as desired, tighten all
bolts.
