Abstract
Abstract 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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
130 words
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.
Claim 2
Dependent Claim
130 words
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.
Claim 3
Dependent Claim
29 words
A prefabricated building panel as defined in claim 1, wherein said maintaining means is an element embedded in said panel and having a screw thread engagement with said positioner.
Claim 4
Dependent Claim
80 words
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.
Claim 5
Dependent Claim
41 words
A prefabricated building panel as defined in claim 3 wherein the upper end of said rod is formed with a screw thread and forms part of said maintaining means, and said positioner carries screw thread means engaging said rod screw thread.
Claim 6
Dependent Claim
22 words
A prefabricated building panel as defined in claim 3 including a depression, in the bottom edge of said panel, surrounding said rod.
Claim 7
Dependent Claim
35 words
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.
Claim 8
Dependent Claim
57 words
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.
Claim 9
Dependent Claim
100 words
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.
Claim 10
Dependent Claim
100 words
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.
Claim 11
Dependent Claim
20 words
A fitting as defined in claim 8 including a sleeve surrounding said positioner, said positioner being movable within said sleeve.
Claim 12
Dependent Claim
35 words
A fitting as defined in claim 8 wherein said sleeve extends below said positioner and accommodates readily crushable means directly adjacent to the end of said positioner having said screw thread relationship with said rod.
Claim 13
Dependent Claim
36 words
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.
Claim 14
Dependent Claim
128 words
A prefabricated cast concrete building panel having top and bottom edges, and including at least one positioner partially embedded in said panel and projecting 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.
Claim 15
Dependent Claim
128 words
A prefabricated cast concrete building panel having top and bottom edges, and including at least one positioner partially embedded in said panel and projecting 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.
