Precast Overhang System / Stay-In-Place Fascia Form (SIPFF)
Reduce skilled labor needed to set bridge overhang and reduce risk associated with setting and removing bridge overhang brackets. Beam flange is loaded evenly, reducing damage to fascia beam during concrete placement. Accelerate bridge construction, one 5′ SIPFF can be set in 5 minutes.
This SIPFF is designed to prevent any issues with web buckling and any damages that can occur to flange from conventional exterior overhang systems. Hardware from upper connection is removed for rail and overpour. Shop control concrete is less permeable than CIP concrete resulting in longer service life and better aesthetics.
The Bridge Overhang Bracket adjusts to fit both structural steel and precast concrete beams. The size and shape of a bracket is adjusted by changing the vertical and diagonal legs to meet the specific overhang forming requirements. Bracket dimensions can be preset on the ground, then moved into position to speed forming operations.
The Bridge Overhang Bracket Extension for wider overhangs, Guard Rail Receptacle for 2×4 uprights, and Wall Plate for wall mounting, are options adding to the versatility of the Bridge Overhang Bracket.
Exterior Hangers generally use two types of end clips, a 450 end to support the overhang and a 900 end to support the interior. Hangers must support the live load, dead load, forming load and/or finishing load.
There are several types of exterior hangers, including Type 1-A, 2-A, 3-A, 4-A, 7-A, 8-A and 9-A.
Exterior Half Hangers
There are several types of standard half hangers, including Type 4-AB, 9-AB, 4-APR and 9-APR.
Interior Hangers are placed on the top of the interior bay beams. Two 900 end clips support the suspended formwork between the beams. Hangers must support the live load, dead load, forming load and/or finishing load.
There are several types of interior hangers, including Type 1, 2, 3, 4, 5, 7, 8 and 9.
Interior Half Hangers
There are several types of standard half hangers, including Type 1-S, 1-C, Precast, Adjustable and Hook.
