Claim 1
Independent Claim
168 words
In a structural supporting complex comprising a pluraliTy of detachably interlocking panels including connecting means on the longitudinal and transverse edges thereof, the improvement which comprises a first panel with a connector of a first connecting means on a transverse edge and a connector of a second connecting means on a longitudinal edge, and a second panel with a connector of a first connecting means on a longitudinal edge and a connector of a second connecting means on a transverse edge, the connectors of the first connecting means on the first and second panels adapted to be interlocked with each other and complementary connectors of the second connecting means on the first and the second panels adapted to be interlocked with each other, the first connecting means being dissimilar from the second connecting means, the panels being suitably interlockingly positioned adjacent to each other with the adjacent first connectors and the adjacent second connectors being detachably interlocked to provide a supporting complex with discontinuous linearly extending joints therebetween.
Claim 2
Dependent Claim
168 words
In a structural supporting complex comprising a pluraliTy of detachably interlocking panels including connecting means on the longitudinal and transverse edges thereof, the improvement which comprises a first panel with a connector of a first connecting means on a transverse edge and a connector of a second connecting means on a longitudinal edge, and a second panel with a connector of a first connecting means on a longitudinal edge and a connector of a second connecting means on a transverse edge, the connectors of the first connecting means on the first and second panels adapted to be interlocked with each other and complementary connectors of the second connecting means on the first and the second panels adapted to be interlocked with each other, the first connecting means being dissimilar from the second connecting means, the panels being suitably interlockingly positioned adjacent to each other with the adjacent first connectors and the adjacent second connectors being detachably interlocked to provide a supporting complex with discontinuous linearly extending joints therebetween.
