Abstract: Resilient and flexible grout seal strips for sealing off a space formed between the bottom of a concrete panel and a support beam on which the panels are supported, concrete panels, decks, and support beams having resilient and flexible grout seals and methods for fabricating such panels, beams and decks are disclosed. The grout seal strips have a first longitudinal edge adapted to be anchored on either the bottom of a precast panel or the top of a support beam adjacent the respective side edge thereof and extend substantially the length thereof, and have an opposed second longitudinal edge with a wide sealing portion therebetween adapted to engage the other of the panel bottom or the beam top adjacent the respective side edge thereof and form a sealing relation therewith.

Abstract: Concrete panels for making concrete decks or floors for spanning between structural supports; parts of such panels including shear connectors, thread formers, and resilient grout seals; tools for manipulating grout-seals; co-acting forms for making panels; interior and overhang panels and apparatuses and methods for fabricating and using such panels. The panels have a seal member device connected to a body member for sealing off a space between the panel and a structural support on which the panel rests.

Abstract: Apparatus and method for pouring concrete on a bridge is disclosed employing rail-mounted pouring and related equipment and separate rail-mounted rolling pipe for attachment to a concrete source system located on an approach to the area to be poured. The equipment rail and rolling pipe rail are both mounted on stable overhang brackets located outboard of the area to be poured. A power tractor is also mounted in the approach area on the rolling pipe rail and straddles the vertical reinforcing members located on the outside edges of the bridge deck. The tractor pushes the rolling pipe and permits a flexible hose connection to a stationary concrete pump located on the approach. A spring-loaded telescoping channel connection allows the trolleys on the tractor and the idler trolleys supporting the rolling pipe to be clamped securely to the rail.

Abstract: A hanger and bracket attached to the hanger for supporting formwork for steel and concrete during the curing stage of a bridge deck overhang is described. A hanger attached to the beam of the bridge supports a connector carrying the bracket. The connector is maintained in a substantially vertical position. The bracket is adjustable in both horizontal angle and in grade because of pivotally attached horizontal members, an adjustable compression leg, and connector means. Once the cement is set the bracket may be recovered for reuse.
