Definitions

  • a prefabricated cast concrete building panel is provided with an embedded fitting comprising a tubular positioner and a rod axially aligned with it.
  • the upper end of the positioner projects from the top edge of the panel, and the lower end of the rod projects from the bottom edge of the panel.
  • the embedded ends of the positioner and rod have a screw thread relationship, so that by rotating the positioner the spacing between its top and the top edge of the panel may be varied.
  • a sleeve may surround the positioner portion within the panel, and crushable means may be located within the panel directly beneath the lower end of the positioner.
  • An opening in the positioner may be provided for engagement by connector means for lifting the panel.
  • This invention relates to prefabricated cast concrete building panels, and more particularly to wall-forming panels and the fittings with which such panels are furnished for a variety of purposes.
  • Hangers-these are loop members adapted to be engaged by hooks of cranes or derricks for lifting the panels into place during construction of the building;
  • Positionersthese are tubes or rods projecting upwardly from the top edge of each panel. After a panel is in place in the building, the bottom edge of the next successive panel is seated on the positioners of the panel in place, to provide a space between the opposed panel edges. The space permits the edges of floor panels to rest on the top edge of the lower wall panel, and ultimately the space is filled with concrete;
  • Joint reinforcements-these are numerous rods projecting from the top and bottom edges of the panel. When the space between successive vertical panels is filled with concrete, these rods furnish continuity of reinforcement between the panels, which themselves include embedded steel reinforcement.
  • FIG. 1 is a perspective view of a building panel according to this invention being placed upon a similar panel already set in place;
  • FIG. 2 is a vertical cross-sectional view through the panel, the central part of which has been broken away so that both the top and bottom edges of the panel can be seen;
  • FIG. 3 is a vertical cross-sectional view through a finished joint between two panels according to this invention.
  • FIG. 4 is a fragmentary bottom view of the panel
  • FIG. 5 is a fragmentary cross-sectional view along line 55 of FIG. 4.
  • FIG. 6 is a fragmentary vertical cross-sectional view through a panel showing an alternative embodiment of the invention.
  • FIG. 1 shows a prefabricated cast concrete panel 10, illustrative of the present invention, about to be assembled with a similar panel 11 already set in place. While panels according to this invention may be of any suitable size, it may help in understanding the invention to point out that a typical panel 10 may be about 30 feet long, about 10 feet high, and about 6 inches thick. The panels may be used to form both exterior walls of the building and interior partitions.
  • Each panel has embedded in it at least one, but preferably several, fittings, and if several are employed they may be spaced every 6 to 12 feet along the length of the panel, depending among other things, upon the dimensions of the panel.
  • a fitting chosen to illustrate the present invention may be seen best in FIG. 2.
  • the principal elements of the fitting are a rigid tubular positioner l4 and a rod 15, both of which may be formed of steel.
  • Positioner 14 is partially and movably embedded in panel 10, its upper portion projectingupwardly from the top edge 16 of the panel.
  • Positioner 14 is provided, in its exposed portion, with two horizontally aligned openings 29, adapted to receive connectors, such as hooks 30 (FIG. 1) of cranes or derricks used to lift panel 10 into place in the building.
  • Rod 15 is much longer than positioner 14, but is of smaller diameter than the positioner, and is almost completely embedded in panel 10, the lower end region of the rod projecting below the bottom edge 17 of the panel.
  • Rod 15 and positioner 14 are axially aligned and preferably vertical when the panel is in its final position in the building.
  • the fitting extends through the full height of the panel (see FIG. 1), its ends projecting above the top edge and below the bottom edge of the panel.
  • the upper externally threaded end 18 of rod 15 is arranged within the lower end of positioner 14.
  • a sleeve 23 which may be for example, of metal, plastic, or cardboard, may he slipped over the lower portion of positioner 14 within the mold.
  • a ring 24 preferably formed of a crushable material, such as foamed plastic or corrugated cardboard, is placed around rod 15 in engagement with the lower end of positioner 14. Concrete is then poured into the mold, and hardens to produce the panel with the fittings embedded in it. The presence of sleeve 23 prevents concrete from engaging positioner 14, whereby the positioner can be moved, within the sleeve, with respect to the hardened concrete panel.
  • Ring 24 prevents concrete from engaging the meshing screw threads of nut 19 and rod end 18, which might otherwise lock these members against relative movement. Furthermore, if ring 24 is crushable, it permits positioner 14 to be rotated in a direction resulting in movement of the positioner into the panel. In other words, if ring 24 were rigid, or not present, the rigidity of the ring or of the concrete would prevent movement of positioner 14 into the panel 10. However, with a crushable ring 24 present, positioner 14 can be rotated in either direction, and is permitted to move into the panel by crushing ring 24.
  • FIG. 6 An alternative embodiment of the sleeve and ring is shown in FIG. 6.
  • sleeve 23' extends downwardly beyond the lower edge of positioner l4 and is formed with an inwardly directed flange at its lower end.
  • Ring 24' is supported on the flange. In this way, the positioner 14, sleeve 23, and ring 24 can be handled as a unit.
  • Panel 10 could be cast with a bore in its top edge aligned with rod 15, and having a diameter slightly larger than that of positioner 14. After hardening of the panel, positioner 14 could then be slipped into the bore and threadably engaged with rod end 18.
  • the bottom edge 17 of panel 10 is preferably formed with a depression 27 (FIGS. 2, 4, and 5) surrounding each rod 15.
  • the depression has substantially a truncated pyramidal shape.
  • Seated against the top wall of depression 27 is a rectangular metal washer 28, about equal in size to the size of the top wall.
  • the width of washer 28, and hence of the depression top wall is about equal to the diameter of positioner 14, as indicated in FIGS. 3 and 4.
  • a prefabricated cast concrete building panel having top and bottom edges, and including at least one elongated hollow positioner projecting upwardly from the top edge of said panel, a portion of the length of said positioner being embedded in said panel, said positioner having an open upper end and being movable vertically with respect to said panel so that the spacing between the top of said positioner and the top edge of said panel may be adjusted, and means carried by said panel for maintaining said positioner in any desired position of adjustment, whereby after the panel is in place forming part of a building, said positioner can be adjusted to locate its top at the most suitable height for engaging and supporting the bottom edge of another similar panel.
  • a prefabricated building panel as defined in claim 1 including at least one rod partially embedded in said panel in alignment with said positioner, the lower end of said rod projecting below the bottom edge of said panel and being sized to fit into the upper end of said positioner, whereby after the panel is in place forming part of a building the upper end of said positioner can accommodate the lower end of said rod of another similar panel.
  • a prefabricated building panel as defined in claim 3 including a depression, in the bottom edge of said panel, surrounding said rod.
  • a prefabricated building panel as defined in claim 1 including at least one opening in the upper projecting part of said positioner for accommodating a connector by means of which said panel may be lifted.
  • a prefabricated building panel as defined in claim 1 including a sleeve embedded in said panel and surrounding the portion of said positioner embedded in said panel, said positioner being movable within said sleeve, said sleeve maintaining said positioner free of engagement with the cast concrete so that said positioner can move with respect to the panel.
  • a fitting adapted to be partially embedded within a cast concrete prefabricated building panel comprising an elongated tubular positioner, a rod concentric with said positioner, and means providing a screw thread relationship between one end of said rod and one end of said positioner, whereby one end of the tubular positioner is closed, said rod extending into only a portion of the length of said tubular positioner, said portion being shorter than the total length of the positioner, the total length of said positioner and rod exceeding the height of the panel with which the fitting is to be used.
  • a fitting as defined in claim 8 including a sleeve surrounding said positioner, said positioner being movable within said sleeve.
  • a fitting as defined in claim 8 including at least one opening in said positioner for accommodating a connector by means of which the panel of which the fitting will form a part may be lifted.
  • a prefabricated cast concrete building panel having top and bottom edges, and including at least one positioner partially embedded in said panel and pro- 5 jecting upwardly from the top edge of said panel, said positioner being movable vertically with respect to said panel so that the spacing between the top of said positioner and the top edge of said panel may be adjusted; readily crushable means within said panel directly beneath the bottom of said positioner; and means carried by said panel for maintaining said positioner in any desired position of adjustment, whereby after the panel is in place forming part of a building, said positioner can be adjusted to locate its top at the most suitable height for engaging and supporting the bottom edge of another similar panel.
