ABSTRACT:
Resilient 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 grout seals and methods for fabricating such panels, beams and decks are disclosed. The resilient 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. The seal strips are sufficiently resilient so as to become deflected when the panel side edge is set down upon the beam and when vertically adjusted relative thereto and thereby maintain a sealing relation to resist horizontal pressure of the concrete or grout introduced into the space and prevent leakage thereof past the engaged seal strip. A two-part grout seal strip has an anchor channel that is embedded in the concrete member and a resilient seal part having a protrusion engaged in the anchor channel. The panels may also be provided with jack screws having a protective foot to prevent tearing the seal strip.
