Adjustable Overhang Bracket


Adjustable Overhang Bracket
The Versatile Bridge Overhang Bracket features maximum adjustability to meet the overhang forming requirements of both steel and precast/prestressed concrete bridge beams. The 22" of adjustment provided by the diagonal leg combined with the 20" of adjustment in the vertical leg, both adjustable in increments of 2", allows for maximum versatility in overhang formwork design. Adjustment is easily accomplished using one 1/2" NC Bolt and Nut per leg meeting ASTM Specification A449. The adjustable nut controls 21" of vertical movement at the outboard end of the bracket to handle the various slopes encountered on bridge overhangs. Overhang brackets set 1/4" to 1/2" above finished grade allows for dead load deflections. If required, final adjustment to grade may be made during the placement of concrete. The adjusting nut also allows the Overhang Bracket to be adjusted downward for easier stripping of the overhang formwork.

Overhang Brackets
Overhang brackets with up to 4,000 lb capacity, depending on anchorage, reduces number of hangers or brackets required. Forming for haunches or fillets simplified. Eliminates cutting deck forms and joists for hanger rods and welding of hangers. Inserts for 3/4" high strength bolts should be positioned when girder is cast or fabricated. Brackets should be bolted tightly to girder.

Heavy Duty Overhang Bracket
C-89 and C-89-L Heavy Duty Bridge Overhang Brackets are designed for maximum adjustment and strength to meet the rigors of heavy cantilever/overhang applications. The C-89 bracket features 72" long, four inch horizontal channels and an overall vertical adjustment range of 27" to 66¾". The C-89-L bracket has 90" long, six inch horizontal channels and an overall vertical adjustment of 29" to 68¾".

Both brackets come equipped with nail holes in the top of the horizontal channels for attaching 2x6 or 2x8 lumber (flat) and both brackets have built-in guardrail receptacles for 2x4 guardrail posts.

The C-89 and C-89-L brackets can be used equally well on steel or precast concrete bridge girders with the appropriate ¾" C-60 45o Pres-Steel Hanger (Type 9-A). The brackets can be shipped "knocked down" for easier handling and shipping and then preset on the ground at the job site.
