Definitions

  • the joint is provided with one or more deformation grooves in its upper surface and a plurality of rigid plates embedded in the elastomer, generally parallel to said surface and adapted to render the joint relatively stiff in the vertical direction and to permit the joint to deform in shear upon reduction of the width of the space between the adjacent sections.
  • the concrete is also poured into forms resting on a suitable substrate or roadbed.
  • These forms divide the highway into discrete sections or slabs of concrete having a length which can vary from about 50 feet to several hundred feet.
  • the thickness of the slabs can vary from about three to about six inches, depending primarily upon the magnitude of the vehicular loads to be supported.
  • a gap of between about onehalf inch and about one inch is provided between the adjacent sections of concrete to allow for thermal expansion and contraction of the sections without the danger of buckling the concrete.
  • a good joint should maintain a tight fit against, and protect the sides of, the concrete slabs which define the gap over a wide range of temperatures and climatic conditions.
  • the joint should present an upper surface which is relatively smooth and is in substantial alignment with the road surface so that there is little or no noticeable vibration or thumping when the tires of a vehicle pass over it.
  • Such a joint should be capable of taking a large and sudden vehicle load with a minimum of vertical deformation, and repeated substantial horizontal deflections without noticeable deterioration or degradation. Moreover, maintenance of such a joint should be minimal.
  • Another object is to provide a joint which forms a tight protective seal with the adjacent edges of the concrete slabs so that water and ice, as well as foreign objects such as stones and dirt, dont penetrate between the road and the joint and deteriorate the road surface.
  • a further object is to minimize the jolt of a vehicle passing over the joint.
  • FIGURE 1 represents a cross section of one concept of the expansion joint, spanning the gap between two adjacent slabs, said joint being provided with longitudi- 3 nally extending deformation grooves on the top and bottom surfaces thereof;
  • FIGURE 2 is a perspective view showing the same joint under compression between the two adjacent slabs
  • FIGURE 3 is another perspective view depicting an alternate design of the joint provided with a singular deformation groove on the upper surface thereof, said groove having a zigzag or saw-tooth configuration;
  • FIGURE 4 shows one means of restraining movement of the upper edges of the expansion joints shown in FIG- URES 1, 2, and 3.
  • FIGURE 5 represents another modification similar to that shown in FIGURE 4 utilizing a tongue and groove joint
  • FIGURE 6 is a cross-sectional view depicting a simplified expansion joint having one deformation groove on the upper surface and one on the lower surface;
  • FIGURE 7 is a cross-sectional view of a simplified joint in which the bottom deformation groove has been omitted;
  • FIGURE 8 is a plan view of two joint sections wherein the rigid plates project from one end of the joint and are adapted to be inserted into appropriate slots in the next section in order to assemble sections end to end across the width of the road;
  • FIGURE 9 shows in cross section a modified joint which can be bolted to the concrete slabs.
  • FIGURE 10 is a cross-sectional view of another variation of a joint provided with means for attaching it to the slabs.
  • FIG- URE 1 and FIGURE 2 there is shown in FIG- URE 1 and FIGURE 2, as one embodiment of the invention, an elastomeric expansion joint 1 spanning the gap 2 between adjacent slabs of concrete 3 and 4.
  • Each slab is provided with a recess, defining shoulders 7 and 8 on which the joint rests.
  • Metal plates 9 and 10 serve to protect the edges of the concrete from cracking and spalling, and to provide a continuous and smooth surface in contact with the joint. These plates, the use of which is optional, are preferably anchored into concrete at the time of pouring.
  • the joint comprises a deformable body of elastomeric material 11 having a top 12 and bottom 13 generally parallel to one another.
  • the joint is of sufficient thickness so that when it is resting on plates 9 and 10 its top surface is substantially flush with the surface of the roadway.
  • Each side of the joint is essentially channel shaped, being provided with an upper flange 16, 17 and a lower flange 18, 19 extending horizontally into abutting contact with the recessed vertical portion of one of the plates 9, 10.
  • the joint is provided with two generally V-shaped grooves 26, 27 on the top surface and at least one groove 28 on the bottom surface, all extending longitudinally of the joint. These grooves serve to compensate for changes in the width of the gap caused by thermal expansion or contraction of the concrete slabs and/ or the bridge beams.
  • Embedded in, or bonded to, the elastomeric body 11 to provide rigidity to the structure are several longitudinally extending rigid plates, arranged substantially parallel to the surface of the road. Plates 20, 21, 22, and 23 extend outwardly from the grooves into the flanged side portions of said joint. Plate 24, substantially wider than the other plates, is situated in approximately the vertical mid portion of said joint. All of these plates provide a sitfening factor for the joint serving as a resistance to the bending movement of the vertical force applied by the weight of a vehicle passing over the joint. Plate 25 is spaced above plate 24 and is located between two grooves 26, 27 near the top surface of the joint.
  • FIGURE 1 shows the joint in its unstressed condition spanning the gap between two adjacent slabs in, for instance, cold weather where, due to the thermal contraction of the concrete, the gap approaches its maximum width.
  • FIGURE 2 shows the same joint under compression caused by a reduction in the width of the gap in, for instance, the summer time. It is noticed in this instance that the width of the upper grooves 26, 27 and the lower groove 28 is substantially reduced due to the deflection of the two top flanges 16, 17 and the two bottom flanges 18, 19 toward the grooves. At the same time the elastomer between the middle plate 24 and the plates 20, 21, 22, and 23 is subjected to shear deformation. These plates impart sufficient rigidity to the expansion joint while compressed between the slabs, to prevent upward buckling of the joint.
  • the longitudinally extending rigid plates serve to minimize vertical deflection of the joint under the load of vehicular traflic.
  • the elastomeric joint is made stiffer than a comparable joint of the same thickness but without these plates.
  • the joint is described as having two grooves in the top surface thereof, it should be understood that one or more grooves may be used, and that their crosssectional shape and longitudinal configuration can be modified without departing from the novel concept therein embodied. Basically, however, the grooves should be dimensioned so that the summation of their width in a given horizontal plane through the joint should be at least as great as the maximum horizontal deflection of the joint in that plane as determined by the expansion and contraction of the adjacent sections of concrete and/or portions of the bridge. Furthermore, the number of flat, parallel reinforcing plates and their relative placement can be altered to regulate the magnitude of the shear deformation and the stiffness of the joint.
  • FIGURE 3 shows another embodiment of the invention wherein the expansion joint is provided with upper and lower deformation grooves, the upper groove 51 having a zigzag or saw-tooth pattern.
  • the spacing between the adjacent waves in the groove is such that at least a portion of a tire rolling over the joint is continuously supported by a surface of the joint which is substantially flush with the surface of the road, thereby minimizing the tell-tail thump commonly felt when passing over the gap.
  • Two rigid plates 53, 54 are embedded in the elastomer near the upper surface thereof, one on either side of the groove.
  • plate 53 terminates near and follows the contour of the groove, and the other edge terminates in upper flange 59, and the other plate 54 is similarly disposed on the other side of the groove 51 terminating in flange 60.
  • a horizontally extending plate 52 having a width slightly less than the width of the body portion of the joint, is disposed intermediate the top and bottom surfaces of the joint separating the upper groove 51 from the lower groove 63.
  • Bottom plates 55, 56 are embedded in the elastomer on either side of the groove 63 and extend out into the bottom flanges 61, 62 of the joint.
  • the joint in FIGURE 3 is adapted to rest on the horizontally disposed portion of appropriate recesses formed in the adjacent concrete slabs 64, 65 provided with metal plates 57 and 58.
  • the upper and lower flanges of the joint abut the vertical shoulder portions of the plates.
  • the gap therebetween contracts causing the joint to be horizontally compressed.
  • the resultant compressive deflection of the upper flanges and of the lower flanges toward one another reduces the width of the upper and lower grooves 51, 63.
  • the horizontally disposed plates in the joint resist the tendency of the joint to bulge or buckle during this compression and likewise serve to minimize vertical deformation of the joint when a vehicle passes over the joint.
  • both of the grooves have a cross section which is essentially V-shaped, and it is obvious that the width of the grooves should be suflicient to accommodate the maximum amount of horizontal deflection which will be encountered. Further, more than one groove can be provided on each surface, and the grooves can be of the same design or different than those shown and described.
  • FIGURES 4 and 5 are shown variations of the joints shown in FIGURES 1, 2, and 3, said variations relating primarily to the design of the plates which are anchored to the concrete and the flanged end portions of the joints.
  • the joint 101 is provided with upper and lower flanged portions 102 and 103 each having a parallel rigid plate 104 and 105 embedded therein and terminating near the end of the flanges.
  • the upper flange is provided with a notch 106, said notch adapted to engage a suitable lip 107 in plate 108 which is anchored in the concrete. The lip prevents the upper flange from raising above the surface of the roadway when, for instance, a heavy vertical load passes over the middle of the joint.
  • FIGURE 5 shows a similar structure, with the exception that the upper flange of the joint 111 is held in place by a tongue and groove joint.
  • the upper flange 110 having plate 111 embedded therein, preferably, but not necessarily, extends out beyond the end of the bottom flange 112 likewise provided with a rigid plate 113.
  • Steel plate 114 anchored in the concrete to form an appropriate recess as hereinbefore described, is provided with an appropriate groove 115.
  • the end of the upper flange forms a tongue which is inserted in this groove.
  • This tongue and groove joint precludes the end of the joint from turning up above the surface of the roadway, and has a further advantage that it prevents downward deflection of the upper flange 110.
  • the upper flange of the joint in either of these embodiments can be bonded to the metal plates utilizing a suitable adhesive or the like to provide a Watertight seal.
  • FIGURE 6 shows a simplified version of an expansion joint 150 held in position in appropriate recesses formed in adjacent concrete slabs 159 and 160.

  • This joint has one V-shaped groove 151 on its upper surface and a similar V-shaped groove 152 on the lower surface, said grooves separated from one another by a transversely extending rigid plate 153 embedded in the elastomer.
  • the upper surface of the joint is substantially flush with the surface of the road, and is reinforced by two plates 154 and 155 bonded to and/or embedded in the elastomer. Plates 156 and 157 reinforce the bottom surface of the elastomer in like manner.
  • top and bottom edges of the joint contact the vertical recessed sides of the plates 161, 162.
  • Each side of the joint is characterized by two surfaces sloping obliquely inwardly from these edges and meeting to form a groove 163, 164 in proxirnity of plate 153.
  • FIGURE 7 shows another design for the joint, this joint being essentially that obtained by slicing the joint of FIGURE 6 horizontally along its mid vertical plane.
  • This joint shown in position between plates 205 and 206 forming and defining appropriate recesses in adjacent slabs of concrete 207 and 208, is provided with one vertical deformation groove 201 in its upper surface.
  • This surface which is substantially flush with the level of the roadway, is provided with rigid plates 202 and 203 extending lengthwise thereof and substantially parallel to the roadway.
  • the sides of the joint contact the steel plates 205 and 206 at or near a point adjacent to the top surface thereof and angle obliquely inwardly and downwardly toward the bottom of the joint.
  • the surface can be made of, or coated with, a lower friction or highly abrasion resistant material such as rigid polyurethane or Teflon.
  • This joint as well as the modification shown in FIG- URE 6 and previously described, can be modified to the extent shown in FIGURES 4 and 5 in order to more securely retain the joint in place in the gap.
