Transverse joint cell for concrete structures
First Claim
Patent Images
1. A transverse joint cell for concrete structures comprising:
- elongated liner means for disposition between adjacent end portions of end to end concrete road slabs;
said liner means including a pair of vertically extending panels spaced apart in substantially parallel relation such that a plurality of compressible blocks may be inserted therebetween;
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;
a plurality of compressible 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 to allow fluid to pass to said gutter means; and
means for securing said liner means to a dowel bar assembly of said concrete road slabs.

Abstract
A transverse concrete pavement joint cell including a pair of plastic walls abutting the edges of the concrete joints. A seamless drainage gutter extends longitudinally between said plastic walls to the edges of the pavement. Blocks of compressible elastomers between said plastic walls absorb expansion of the concrete. The cell includes a base and stabilizing ties secured to a conventional dowel bar assembly.

17. In combination with adjacent slabs of pavement separated by a joint space:
-
wall liner means including elongated spaced panels extending parallel to each other; support means to support said liner means on a substantially flat surface within such a joint space; seamless drainage means extending between said elongated spaced panels throughout the length of said joint space, said wall liner means having accessible outlets at each ends of the joint; and a plurality of compressible block means disposed between said panels and spaced throughout the length of said panels for compensating for expansion and contraction of such adjacent slabs of pavement, said block means being constructed and arranged to allow fluids to pass downwardly therebetween to said drainage means.

18. A transverse joint cell to be used for compensation for expansion and contraction of end to end panels of a concrete road comprising:
-
water impermeable liner means comprising a pair of vertically extending side walls constructed and arranged to be spaced apart in substantially parallel relation between the ends of such panels such that a plurality of compressible blocks may be inserted therebetween; said side walls being constructed and arranged to define an upper longitudinally extending void to provide a guide for an upper joint forming head; means for supporting said liner means between such end to end concrete panels; spaced compressible block means formed of an elastomer for absorbing compression due to expansion of such adjacent concrete panels and disposed between and throughout the portions thereof intermediate the ends of said vertically extending side walls in spaced apart relation so as to allow fluids and noncompressibles to pass downwardly therebetween; and a seamless drainage trough extending longitudinally of said side walls and said expansion joint and below said compression block means in fluid tight relation to said liner means.

19. A transverse joint cell comprising:
-
a water-impermeable liner means disposed between adjacent transverse joint edges of concrete pavement, said liner means defining an open cell therebetween; support means for supporting said liner means; compressible 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; and 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. - View Dependent Claims (20, 21, 22)
