Install Support Bars, Corrugated Metal, and Deck Rebar 11
6.0 Install Support Bars, Corrugated Metal, and Deck Rebar
6.1 Support Bars
2" x 3/16" steel bar stock bolted between cross beams support the corrugated sheet metal that forms the bottom
surface for the concrete deck pour. Several different lengths of support bars are necessary for most scale lengths.
See the attached blueprint of the scale to determine where each of the different lengths are located in the frame.
Unload the support bars from the hardware box on the truck. Each group
of similar-length bars is bundled separately and marked. Keep equal
length bars together in separate piles.
Install all support bars onto the 3/8" threaded studs per locations shown in the
blueprint. Turn a hex nut onto each stud and tighten securely.
At each load cell mount location, the bottom flange of the 24" siderail I-beam
has been cut out for the load cell window. To support the sheet metal where the
flange is gone, a short support bar is installed next to the load cell window as
shown at left.
6.2 Corrugated Metal Sheeting
Lay in 28 gauge, 3/4" corrugated galvanized panels (1-1/4" wide corrugations) to support the concrete deck pour.
Lay the panels parallel to the cross beams so they are resting on the support bars and the I-beam flanges. Overlap
adjoining panels at least 9" or three full corrugations. Overlap ends at least 12".
Do not use galvanized panels lighter than 28 gauge, or with corrugations more than 1-1/4” wide!
Panels must fit closely to vertical webs of all I-beams to prevent concrete runout
during the deck pour. Cut out accurate slots in the corrugated metal for clearance
around the vertical gussets in the siderail beams and around the drain tubes on
the cross beams. A metal-cutting snips is the best tool for this work.
Cut out clearance sections in the panels for drain tubes where necessary. Slide
the main panel into place, then make a larger overlapping panel section with a
slot cut out for the drain tube. Slide the overlapping panel into place aligned with
corrugations of the main panel. Use duct tape to seal the panel for the concrete
deck pour
