Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
117 words
A building component comprising an integrally cast concrete unit having a floor panel, parallel upstanding walls and a third upstanding wall connecting the ends of said parallel walls, said unit having on its upper wall and lower floor surfaces at least three pairs of metal bearing plates embedded in said concrete and held in parallel precise vertically aligned spaced relation by vertically extending solid connecting rods, whereby regardless of dimensional discrepancies in the remaining surfaces of the unit, said plates act when an equal number of said units are stacked on one another in two separate columns to position said units so that their heights at the upper surface of the topmost bearing plates will be equal.
Claim 2
Dependent Claim
117 words
A building component comprising an integrally cast concrete unit having a floor panel, parallel upstanding walls and a third upstanding wall connecting the ends of said parallel walls, said unit having on its upper wall and lower floor surfaces at least three pairs of metal bearing plates embedded in said concrete and held in parallel precise vertically aligned spaced relation by vertically extending solid connecting rods, whereby regardless of dimensional discrepancies in the remaining surfaces of the unit, said plates act when an equal number of said units are stacked on one another in two separate columns to position said units so that their heights at the upper surface of the topmost bearing plates will be equal.
Claim 3
Dependent Claim
29 words
A building component as claimed in claim 1 having three of said plate pairs to provide tripodal support for each unit as it is stacked on an underlying unit.
Claim 4
Dependent Claim
27 words
A building component as claimed in claim 1 having in addition means for guiding the units in each column into precise horizontal alignment as they are stacked.
