ABSTRACT:
The present invention relates to interlocking construction elements useful in being assembled into load bearing traffic ways. The present construction elements are comprised of a flat top slab and at least one support stem attached perpendicularly to bottom of the slab. The top of the slab is a load bearing surface. The support stems have a flared, or finned, portion positioned contiguous to the junction of the stem and the bottom of the slab. A load placed atop the load bearing surface is equally distributed to the support stem, or stems. The slab may be considered as floating, that is, the bottom of the slab is in touch contact but not in support contact with the foundation. Any weight placed load bearing surface is immediately and directly transmitted to the support stem, or stems in substantially equal proportion. In an alternative embodiment of the invention the support stem, or stems, are secured into a anchor boot, which, in turn, is securedly attached to a foundation. The present elements are suitably utilized in conjunction with other similar elements which are suitably disconnectably interlocked with each other to form a stable, composite load bearing surface.
