1. A load transfer cell assembly for concrete structure comprising:

  • (a) elongated liner means for disposition between adjacent end portions of end to end concrete slabs;

    (b) said liner means including a pair of panels each extending vertically in a single plane and defining an open cell therebetween and being spaced apart in substantially parallel relation such that a plurality of compressible block may be inserted therebetween;

    (c) said liner means further including gutter means extending longitudinally between said vertically extending panels and therebetween in position to collect and drain away fluid which may pass downwardly therebetween;

    (d) plurality of compressible and resilient blocks disposed between said vertically extending panels throughout the portions thereof intermediate the ends of said panels in spaced apart relation so as to provide vertical drainage openings therebetween to allow fluid to pass to said gutter means;

    (e) means for securing said liner means to a load transferring dowel bar assembly of such concrete slabs; and

    (f) mechanical compression means engaging opposite sides of said compression blocks and holding the same under compression therebetween at all times, said compression means being constructed and arranged to extend between adjacent ends of such concrete slabs and to be rigidly secured thereto whereby a load carried by one of such slabs will be transferred in part of least through said compression means and said compression blocks to the other of such slabs.
