Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
A frame structure comprising a pre-fabricated concrete first frame element, said first frame element comprising a pair of spaced sides and at least one lateral cross piece connecting said sides intermediate the ends thereof, said sides having outer and inner surfaces and end surface means extending therebetween, means for reinforcing and for interconnecting said spaced ends of said first element to and for aLigning the same with the spaced ends of a like element, said last mentioned means having spaced, opposed sides extending substantially coplanar with said outer and inner concrete side surfaces of said element from and adjacent to said end surface means for aligning said ends to the ends of a like element and means for connecting said opposed sides of said reinforcing, interconnecting and aligning means, said connecting means extending between and connecting said opposed sides and being embedded in the concrete of said spaced ends for reinforcing the same and defining channel means for receiving fastening means therethrough for interconnecting said ends to the ends of a like element.
Claim 2
Dependent Claim
173 words
A frame structure comprising a pre-fabricated concrete first frame element, said first frame element comprising a pair of spaced sides and at least one lateral cross piece connecting said sides intermediate the ends thereof, said sides having outer and inner surfaces and end surface means extending therebetween, means for reinforcing and for interconnecting said spaced ends of said first element to and for aLigning the same with the spaced ends of a like element, said last mentioned means having spaced, opposed sides extending substantially coplanar with said outer and inner concrete side surfaces of said element from and adjacent to said end surface means for aligning said ends to the ends of a like element and means for connecting said opposed sides of said reinforcing, interconnecting and aligning means, said connecting means extending between and connecting said opposed sides and being embedded in the concrete of said spaced ends for reinforcing the same and defining channel means for receiving fastening means therethrough for interconnecting said ends to the ends of a like element.
Claim 3
Dependent Claim
53 words
The frame structure of claim 1, wherein several of said first elements are interconnected at abutted ends thereof, said interconnecting means further comprising plates having holes aligned with said channel means in adjacent element ends and fastening means extend through said holes and channel means for securing said plates and said ends together.
Claim 4
Dependent Claim
36 words
The frame structure of claim 1 wherein individual interconnecting means are U-shaped, the transverse portion of the U being substantially flat and extending across a respective end of said element for flat abutment with like elements.
Claim 5
Dependent Claim
33 words
The frame structure of claim 3 wherein at least two said first elements are interconnected at abutted ends thereof, said abutted ends having respective complimentary projecting and recess means for interfitting alignment thereof.
Claim 6
Dependent Claim
82 words
The frame structure of claim 1, wherein at least a pair of said first frame elements are interconnected at abutted ends thereof and are both interconnected intermediate their ends to the ends of a brace beam frame element, the latter extending in a plane perpendicular to the plane of the first element and comprising a pair of spaced apart beams and V-shaped braced means for connecting the beams intermediate the ends thereof at the apex and ends of said V-shaped braced means.
Claim 7
Dependent Claim
27 words
The frame structure of claim 5, wherein a plurality of opposing first frame elements and opposing brace beam elements are interconnected to form a main frame unit.
Claim 8
Dependent Claim
35 words
The frame structure of claim 6, comprising a plurality of main frame units arranged in a predetermined spaced apart relation and means are provided for connecting said main frame units in said spaced apart relation.
Claim 9
Dependent Claim
35 words
The frame structure of claim 7, wherein said last named means comprise prefabricated concrete beams connecting said units in planes parallel to the planes of said brace beam frame elements and said first frame elements.
Claim 10
Dependent Claim
43 words
The frame structure of claim 7, further comprising a plurality of columns of first frame elements interconnected at abutted ends and disposed exteriorly of said main frame units and means connecting said columns to said units and to one another in spaced relation.
