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.
Claims13
A precast concrete panel with a top and a bottom adapted to be assembled above a beam with one side edge thereof overlapping a side edge of the beam, whereby concrete or grout may be introduced through an end of a space between the bottom of the panel and the top of the beam which is adjacent the one side edge of the panel so as to support the panel from the beam, and a thin, elongate strip having
- hinge means along a length of the strip intermediate elongate portions on opposite sides of the hinge means, and
- anchor means on an upper face of the strip adjacent the hinge means and cast into the bottom of the panel at a location which disposes the hinge means approximately over the side edge of the beam,
- said strip being formed of a relatively stiff material and said hinge means being formed integrally with the elongate portions of the strip to dispose said portions in general alignment with one another, when the hinge means is unstressed, whereby the upper face of the strip may provide part of a form for the bottom of the panel during casting, and
- said hinge means being flexible to enable an inner elongate portion of the strip to be swung downwardly and outwardly to a position, whereby the panel may be assembled over the beam into a position in which said upper face of the inner elongate portion is yieldably urged against and slidable over the side edge of the beam so as to resist the outward force of the concrete or grout entering the space.
For use in sealing off a space formed between a top of a beam and a bottom of a precast concrete panel whose side edge overlaps a side edge of the beam, whereby concrete or grout may be introduced through an end of the space between the bottom of the panel and top of the beam which is adjacent the one side edge of the panel so as to support the panel from the beam,
- a thin, elongate strip having
- hinge means along a length of the strip intermediate elongate portions on opposite sides of the hinge means, and
- anchor means on an upper face of the strip adjacent the hinge means and adapted to be cast into the bottom of the panel at a location which disposes the hinge means approximately over the side edge of the beam,
- said strip being formed of a relatively stiff material and said hinge means being formed integrally with the elongate portions of the strip to dispose said portions in general alignment with one another, when the hinge means is unstressed, whereby the upper face of the strip may provide part of a form for the bottom of the panel, and
- said hinge means being flexible to enable an inner inner elongate portion of the strip to be swung downwardly and outwardly to a position, whereby the panel may be assembled over the beam into a position in which said upper face of the inner elongate portion is yieldably urged against and slidable over the side edge of the beam so as to resist the outward force of the concrete or grout entering the space.
