Definitions

  • the invention relates to a covering over expansion joints in traffic routes, in particular bridges, from a strip of block-shaped elastomer laid in recesses in the carriageway on both sides of the joint, seen in cross section, the inserts serving for stiffening at least in the covering area of the joint and in the area of its longitudinal edges connecting parts has tensile anchoring in the pavement substructure.
  • an elastomeric plate is anchored on both sides in the joint edges under tension. Due to the associated high material load, the aging of the material is accelerated; the elastomeric material creeps apart in the direction of the tensile force, so that the preload is reduced over time. The elastomeric plate is then subjected to pressure and bulges upwards.
  • the invention has for its object to provide a cover of the type mentioned with high elasticity both in the tensile and compressive range and high load-bearing capacity, which maintains a stable, any bulging position in all deformation states or expansion joint widths.
  • the inserts are coils arranged at intervals next to one another and made of spring wire or similar hard-elastic material, the longitudinal axes of which extend transversely to the longitudinal direction of the joint and the ends of which are each connected to the connecting parts in a tensile manner.
  • the spirals act in the sense of a stiffening insert that increases the load-bearing capacity; at the same time, the elasticity and flexibility of the elastomeric strip does not impair its elasticity, so that relatively small strip widths can be used.
  • the coils cast or vulcanized into the elastomeric strips form an adhesive bond with the elastomeric material, which preferably consists of synthetic rubber and / or natural rubber.
  • the coils are made of hard elastic material, either metal or plastic.
  • the elasticity and load-bearing capacity of the helixes can be adapted to the respective conditions by a suitable choice of the turns.
  • the load-bearing capacity of the strip according to the invention is the tensile anchoring of the ends of the coils on the adjacent connecting parts of the strip, which serve for anchoring in the concrete substructure.
  • the coils are arranged eccentrically closer to the contact surface of the elastomeric strip opposite the surface being traveled on, results in a low center of gravity; this causes the elastomeric plate to be pressed down under pressure.
  • An increase in the load-bearing capacity can be achieved with one embodiment if, with a sufficient thickness of the elastomeric strip, the helices are arranged one above the other in several layers.
  • the cross-sectional shape can deviate from the circular shape, e.g. be elliptical.
  • the longitudinal axes of the coils can be curved in the vertical plane.
  • a particularly interesting expedient embodiment of the invention consists in that the volume enclosed by a helix is designed as a cavity.
  • the be Special advantage of this embodiment is that the elastomeric material can be displaced into the cavity when the strip is deformed without the outer contour of the strip being deformed.
  • This embodiment can also be produced in a particularly simple manner in that the coils are each seated on a core corresponding to their interior during vulcanization.
  • the cavity has the shape of an internal thread and limit the turns of the coil in the area of the thread webs to the cavity.
  • the core used here during vulcanization, on which the coil sits has the shape of a correspondingly dimensioned screw, so that it can be unscrewed after curing.
  • the material is displaced in the area of the thread grooves of the hollow mold. Accordingly, in this embodiment there is no narrowing of the cavity within the helix.
  • this shape of the cavity is advantageously used in that a slide rod, which is displaceably encompassed by the turns of the helix, is arranged at least in the overlap region of the joint.
  • Such a slide bar can be held in the middle above the joint gap by means of any control parts; but it can also be anchored at one end in the edge region of the strip, so that its free end is in the narrowest joint position near the opposite edge of the strip and in the widest joint position above the opposite joint edge. Since in this embodiment the slide rod does not slide on rubber but on the inner surface of the associated helix, signs of wear can be reduced to a minimum; in addition, this embodiment offers the possibility of accommodating a supply of grease in the thread grooves of the cavity. This results in a significant reduction in wear and the coefficient of friction of the sliding movement compared to a known embodiment in which steel rods engage directly in holes in the rubber material (DE-A-2314967). As in the known embodiment, the slide rods improve the load capacity of such joint covers significantly. It is also practically impossible for the elastomeric strip to bulge under pressure.
  • the elastomer zone in the immediate area around the coil can be stiffened by means of a fabric hose which surrounds the coil at a distance, so that the reduction in the material cross section caused by the cavity is compensated for again.
  • the elastomeric strip can be structured in the longitudinal direction of the joint in such a way that support areas alternate with areas of high deformability and the support areas contain the coils.
  • the deformation areas can preferably be designed as a folding mechanism with a folding direction running transversely to the joint;
  • a rope reinforcement extending over the entire length of the joint can be cast or vulcanized into the upper and lower webs of the folding mechanism. In this way it is possible that the folding mechanism can introduce the load into the supporting areas.
  • the rope reinforcement also has the important task of absorbing the stresses in the webs resulting from the folding movement.
  • the rope reinforcement prevents the support areas containing the coils from buckling sideways when the joint is tight. This effect occurs particularly perfectly if the load-bearing areas are webs which run alternately at an angle to the longitudinal direction of the joint.
  • the opposing tendency to deform the supporting areas is prevented by the ropes running in the longitudinal direction of the joint.
  • the elastomeric strip can also be designed as a folding unit extending over its entire length with folding lines parallel to the longitudinal direction of the joint; the coils can correspond at least to the folding height, at least in the dimension of their cross section extending perpendicular to the strip plane.
  • Fig. 1 shows a cross section through an elastomeric strip 1 made of rubber-like material, in which a coil 2 made of wire is vulcanized in the lower part as an insert.
  • the strip 1 covers the joint 3, which is delimited by the joint edges 4 and 5, in a watertight manner.
  • the elastomeric strip 1 lies on the horizontal surface 7 of the concrete substructure forming the joint edges.
  • the elastomeric strip 1 has at the opposite edges angled connecting parts 8 and 9, the horizontal legs 10 and 11 of which are fastened to the concrete substructure by means of screws, not shown.
  • the connecting parts 8 and 9 in the form of the angle profile supports and the helices 2 are inextricably connected to the elastomeric material by vulcanization.
  • the helix 2 with its two ends is connected to the angle section supports e.g. connected tensile by a screw connection, not shown. Seen in the longitudinal direction of the joint, a larger number of the coils 2 shown are arranged next to one another at a distance.
  • Fig. 2 shows a cross section through a helix with circular turns
  • Fig. 3 with oval turns
  • Fig. 4 with egg-shaped turns, wherein a coil with a circular cross-section is arranged within the coil with an egg-shaped cross-section in the lower part.
  • Fig. 5 shows a schematic representation of a coil in which turns with small and large cross-section alternate.
  • the turns are narrower in a first section and further wound in a second section.
  • Wen deln which represent only a small part of the conceivable variations, can be chosen by a person skilled in the art to adapt to the special demands of a joint cover.
  • connection part 8 which is designed as a diaper profile carrier.
  • 8 shows, on the basis of a schematic cross-sectional representation through a helix 15, how its interior is designed as a cavity 16.
  • 8 has the hollow shape of an internal thread, the turns of the helix 15 adjoining the hollow shape in the region of the thread webs 17.
  • a slide rod 18 is guided inside the turns of the helix 15 and serves to increase the load-bearing capacity of the joint cover.
  • the thread grooves 19 formed by the hollow shape can serve as storage spaces for the accommodation of a grease.
  • FIG. 10 shows a partial longitudinal section through a cover strip which has cavities 20 and 21 which are open towards its supporting surface 6, for example with a trapezoidal or arcuate cross section.
  • the webs of rubber-elastic material remaining between the cavities 20 and 21 serve to accommodate the coils.
  • a helix 22 with a circular cross section and a helix 23 with alternating circular and oval turns are shown.
  • FIG. 9 shows a section according to IX-IX of FIG. 10. Accordingly, the cavity 20 extends only over part of the width of the elastomeric strip 1.
  • the cavities are provided 24 and 25 run over the entire width of the elastomeric strip, as is also the case for the helical cross-section 26.
  • 11 corresponds to a section according to XI-XI of FIG. 12.
  • the half section shown in FIG. 13 extends transversely to the joint in the area of a folded section of the elastomeric strip 1, such deformation areas alternating with supporting areas when viewed in the longitudinal direction of the joint.
  • cable reinforcements 28 are cast or vulcanized into the upper and lower webs of the folding mechanism and transmit the loads to the adjacent supporting region.
  • Such support areas can, for example, be designed in accordance with the webs between the cavities 20 and 21 of FIG. 10 or 24 and 25 of FIG. 12, that is to say each comprise a helix.
  • FIG. 14 shows in the plan a sequence of support areas T and deformation areas V, the cable reinforcements 28 of the upper webs of the folding mechanism each being indicated by a line running in the longitudinal direction of the joint.
  • the spirals 29 of the support areas T are indicated by dashed lines.
  • the folding mechanism shown in FIG. 13 can have the same height as the supporting areas; but it can also, as shown in FIG. 13, be offset upwards with its lower folding webs 30 with respect to the support surface 6.
  • 16 and 17 is the joint covering elastomeric strip 1 in its entirety trained as a folding unit.
  • 16 shows an enlarged section of this folding mechanism according to section XVI-XVI of FIG. 17, which shows the schematic plan view of a section of the cover strip in the longitudinal direction of the joint.
  • a helix 35 with the cross-sectional shape of the folding mechanism of appropriate height and slope is surrounded on all sides by elastomeric material.
