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.

Abstract
A non-corrosive load transfer cell assembly for transverse joints in concrete pavement structures including support chairs, a pair of plastic walls abutting the edges of the concrete joints, a drainage trough for continuous drainage flow, a joint forming guide to wet form the upper portion of the joint through the concrete material, and compressed elastomers which space the wall liners apart and cooperate with threaded compression means to provide a load transfer supplement to steel dowels which pass through the elastomers.

16. A load transfer cell assembly comprising:
-
(a) a water-permeable liner means disposed between adjacent transverse joint edges of concrete pavement; (b) said liner means defining an open cell therebetween and included a pair of spaced liner panels each extending in a single vertical plane and defining said open cell; (c) support means for supporting said liner means; (d) compressible and resilient block means for absorbing compression due to expansion of adjacent concrete panels, and disposed between and throughout the length of said liner means and being constructed and arranged to allow fluids to pass freely downwardly in the joint cell; (e) seamless drainage trough means extending transversely through said open cell and in fluid tight relation to said liner means and being constructed and arranged below said compression block means; (f) a dowel bar assembly extending between said adjacent transverse joint edges of concrete pavement and embedded within said pavement; (g) means for securing said liner means to said dowel bar assembly; and (h) mechanical compression means engaging opposite sides of said block means and holding the same at all times under compression therebetween, said compression means extending between said joint edges of concrete pavement and being embedded in the concrete pavement whereby a load carried by said concrete adjacent one of said joint edges will be transferred in part at least through said compression means and said block means to the concrete adjacent the other of said joint edges. - View Dependent Claims (17, 18, 19, 20)
