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.

For use in locating one side of a precast reinforced concrete panel with respect to an adjacent surface,
- an interiorly threaded tubular member which is open at both ends,
- means on the member for securing it to longitudinally extending reinforcing strands within a bed in which the panel is to be cast so that the upper and lower ends of the member will be adjacent the opposite sides of the panel, when cast, and for spacing the member a predetermined lateral distance from an end of the bed and thus an end of the panel,
- a bolt adapted to be threadedly received in the member for axial extension from one end thereof into engagement with the surface in order to locate one side of the panel a desired distance from the surface.
A panel comprising
- a body of precast concrete having longitudinally extending reinforcing strands embedded therein,
- a thread former comprising
- an interiorly threaded, open ended tubular member cast into the body and having open ends adjacent opposite sides of the panel,
- a bolt adapted to be threadedly received in the body for axial extension from one end of the body in order to engage and threrby locate one side of the body a desired distance from a support surface, and
- means on the member securing it to adjacent strands in a bed in which the body is cast so that the upper and lower ends of the member will be adjacent the opposite sides of the panel, when cast, and for spacing the member a predetermined lateral distance from an end of the bed and thus an end of the panel.
