Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
A floor module structure, comprising a steel base plate, a plurality of steel longitudinal spaced bars welded to the bottom side of said base plate and extending longitudinally under said base plate to provide vertical support for limiting vertical deflection when sustaining heavy loads, said base plate having a top surface, a wearing surface material affixed to and covering said base plate top surface, a plurality of steel cross bars welded transverse across the bottom of said longitudinal bars at the ends and extending the width from one bar to another for providing holding support of said longitudinal bars in position when assembling and for providing stiffening and limiting vertical deflection during fabricating of said floor module to provide a flat base plate top surface and said cross bars are angle bars.
Claim 2
Dependent Claim
132 words
A floor module structure, comprising a steel base plate, a plurality of steel longitudinal spaced bars welded to the bottom side of said base plate and extending longitudinally under said base plate to provide vertical support for limiting vertical deflection when sustaining heavy loads, said base plate having a top surface, a wearing surface material affixed to and covering said base plate top surface, a plurality of steel cross bars welded transverse across the bottom of said longitudinal bars at the ends and extending the width from one bar to another for providing holding support of said longitudinal bars in position when assembling and for providing stiffening and limiting vertical deflection during fabricating of said floor module to provide a flat base plate top surface and said cross bars are angle bars.
Claim 3
Dependent Claim
74 words
A floor module structure as defined in claim 1, wherein said wearing surface material is a plurality of longitudinal floor strips affixed to each other to form a laminate, said laminate is affixed to said base plate, and said laminate of longitudinal strips substantially covers and extends over the length and width of said base plate thereby providing a wearing surface material on a firm base for supporting extremely heavy dynamic and static loads.
Claim 4
Dependent Claim
47 words
A floor module structure as defined in claim 2, wherein said floor strips are wood strips cemented together side by side to form said laminate and said laminate is affixed to said base plate top surface by tightening together with a plurality of threaded bolts and nuts.
Claim 5
Dependent Claim
29 words
A floor module structure as defined in claim 1, wherein said wearing surface material is a cementitious compound affixed to and covering the top surface of said base plate.
Claim 6
Dependent Claim
15 words
A floor module structure as defined in claim 4, wherein said cementitious compound is concrete.
Claim 7
Dependent Claim
17 words
A floor module structure as defined in claim 4, wherein said cementitious compound is an epoxy compound.
