Definitions

  • the present sealing device relates to an expansion gap. Such gaps are maintained between adjacent construction members, for example, slabs of concrete forming the roadbed on bridges or the like. A plurality of gap strips are inserted into such gaps and sealing means of elastic material are inserted between adjacent gap strips or between a gap strip and the edges of the construction member which define the gap.
  • the invention provides carrier bars which extend directly through apertures in the gap strips and which are supported at their ends in recesses of the edges defining the gap.
  • Bearing means of elastic material are provided between the gap strips and the carrier bars.
  • the bearing means are firmly secured to the carrier bars and to the gap strips.
  • the bearing means comprise the glide pieces permitting a gliding movement between the bearing means proper and the carrier bars.
  • the present invention relates to a sealing device for expansion gaps in bridges, roadbeds, or any other construction members which are subject to expansion and contraction due to temperature changes.
  • expansion gaps extend at an angle across the longitudinal direction of the construction members, for example the longitudinal extension of the road.
  • These sealing devices comprise gap strips usually made of steel which are laterally supported relative to each other and to the gap by means of elastic bodies which simultaneously function as sealing strips.
  • the gap strips are usually supported on top of carrier bars which extend laterally relative to the longitudinal extension of the gap and are supported in the edges of the construction members which define the gap.
  • Swiss Pat. No. 408,089 describes a prior art expansion gap bridging or sealing device in which each gap strip is rigidly connected to several cross carrier bars which are arranged underneath the gap strips.
  • the cross carrier bars to which one gap strip is connected are shiftably supported inthe gap edge means so as to be movable relative to the remaining cross carrier bars and the gap strips connected to such remaining cross carrier bars.
  • This known device requires a relatively large number of cross carrier bars because due to static and dynamic reasons several cross carrier bars are required for supporting each gap strip.
  • the depth of the gap may have to be increased in order to provide space for supporting the cross carrier bars which are arranged underneath the gap strips, in lower positions, in order to accommodate such larger height of the gap strips where the top edge of the gap is given or determined by the top surface of the construction members.
  • increasing the gap depth is generally impossible without especially considering this problem at the construction site. In those instances where the superstructure has a given height deepening of the gaps is entirely impossible.
  • German Pat. No. 933,157 also describes devices of the type described above in which the gap strips are supported on angle brackets cross bars or the like without being rigidly connected thereto. Due to the fact that the cross bars are not rigidly connected to the gap strips the known structures increase the danger that the gap strips may be tilted by vehicles traveling over the sealing structure. The tilting may be to such an extent that a disadvantageous line of contact results between the gap strips and the cross bars. Similar considerations apply to German Patent Publication 1,257,186 wherein a guide thorn is inserted through the gap strips. However, the guide thomhas no supporting functions.
  • the bearing means as well as the sealing bodies or strips of elastic material in such a manner and to suitably position these elements so that they can cooperate in controlling the position of the gap strips by restoring the gap strips into the desired positions subsequent to a shift resulting from the traffic moving over the sealing device.
  • a sealing or bridging device for expansion gaps between construction members such as roadbeds, especially on bridges and the like wherein gap strips which extend across or at an angle relative to the longitudinal direction of the road support each other by means of elastic bodies, such as sealing strips, whereby the gap strips are supported by means of carrier bars which extend across the gap and wherein the ends of the cross bars are supported by means which are located in the edges, preferably in recesses of the edges of the gap so that said cross bars extend through apertures in the gap strips, whereby the latter can now extend into the space which heretofore has been taken up by the supporting cross bars.
  • the gap strips and the cross bars are firmly secured to each other by means of bearings made of elastic material such as elastomers of the rubber, neoprene, polyurethane type or the like.
  • the structure is such that the carrier cross bars are supported in the gap strips by glide bearing means which are secured to the gap strips but which permit a relative sliding movement between the gap strips and the carrier cross bar.
  • glide bearing means which are secured to the gap strips but which permit a relative sliding movement between the gap strips and the carrier cross bar.

  • FIG. 10 illustrates an embodiment wherein a firm connection between a glide piece and a bearing body of elastic material as well as between said bearing body and the gap strip pemiits a gliding movement of the gap strip in its longitudinal direction across the carrier bar;
  • FIG. 11 shows a modification similar to that of FIG.
  • FIG. 1 shows a top view of two concrete slabs l and 2 forming, for example, the road surface on a bridge.

  • sealing means in the form of elastic or resiliently yielding bodies or strips 17 to form a continuous and smooth surface of the sealing device which surface will be flush with the road surface.
  • These elastic or resiliently yielding means 17 may, for example, be strips of polyamide, Teflon (R.T.M.), or the like which provide a lateral support for the gap strips 11.
  • the lower ends of the gap strips 11 are also laterally supported relative to the edge profile or relative to the gap and relative to each other by resilient or elastic control means such as steel springs or bodies of elastomer material.

  • This gap strip comprises an upper rod 20 and a lower rod 21 which are interconnected with each other by means of cross pieces 22.
  • the interconnection between the rods and the cross pieces may be permanent or removable as will be explained with reference to FIG. 4.
  • the cross pieces 22 are spaced from each other so as to provide apertures 23 through which the carrier cross bars 6 extend.
  • the cross bars 6 may be provided with longitudinal ridges 24 which act to limit any lateral shifting of the cross bar relative to the glide pieces 15 or vice versa.
  • FIG. 4 illustrates several possibilities of interconnecting the upper and lower rods 20 and 21 with the cross pieces 22 in order to form the gap strips according to the invention.
  • the upper rod 20 is connected to the cross pieces 22 by means of threaded bolts 25. This has the advantage that the upper rods of the gap strips which are subjected to the traffic conditions of the road may be easily replaced when they are worn out.
  • the lower rod 21 is shown to be connected to the cross pieces 22 by means of weldment 26. It is to be understood that various modifications and combinations of the interconnections between the rods and the cross pieces are within the scope of the present invention.
  • the cross pieces 22 as elements which are divided along a central line of symmetry extending longitudinally through the gap strips and having lugs 27 which are interconnected with each other by means of nuts and bolts 28.
  • the sealing strip 17 and the spring means 18 are arranged in a mirror symmetrical fashion rela tive to the longitudinal axis of the carrier cross bar 6 so that the biasing forces will be perfectly balanced.
  • the spring means 18 may also be provided in the form of elastically yielding or resilient sealing strips so that the entire device will be sealed not only at the surface of the road but also at the bottom of the expansion gap.
  • the sealing strips it is possible to insert elastically elastically supporting bodies between adjacent gap strips and between gap strips and the edge means 4, 5, whereby these additional supporting bodies may operate as buffers and as stop means for limiting the lateral movement of the gap strips.
  • FIG. 5 illustrates a view similar to that of FIG. 3.
  • two gap strips 29 and 30 are shown to extend in parallel one behind the other. Only one half of each gap strip is visible because the left hand portion of the gap strip 30 is broken away along the line 31 in order to expose the gap strip 29 which is located behind the gap strip 30.
  • the gap strip 29 comprises an upper rod 32 and a lower rod 33 interconnected by pieces 34, 35 which preferably have a mirror symmetrical shape.
  • the interconnection between the cross pieces on the one hand and the upper and lower rods 32, 33 may, for example, be accomplished as has been described above with reference to FIG. 4.
  • the cross pieces 34, 35 are shaped and spaced from the adjacent pair of cross pieces 36, 37 so as to provide an aperture comprising an upper trapezoidal half 38 and a lower trapezoidal half 39.
  • the upper half 34 of the cross piece has also a trapezoidal shape in such a manner that it fits into the lower half 39 of the aperture.
  • the lower half 35 of the cross piece which will fit into the upper half 38 of the aperture. In this manner there is substantially no waste of any material.
  • the gap strip strip 30 is constructed in the same manner as has just been described with reference to gap strip 29.
  • the respective elements 32' to 39' are also arranged relative to an axis ofsymmetry 40.
  • a carrier bar 49 extends through the aperture formed by aperture portions 38, v39.
  • a further carrier bar 42 extends through the aperture formed by aperture portions 38", 39'.
  • the gap strip 29 is supported on the carrier bar 41 by means of bearing blocks 43.
  • the gap strip 30 is supported on carrier cross bar 42 by means of bearing bocks 44.
  • carrier cross bars 49, 42 will be spaced from each other by approximately 3 to 5 meters. This relatively wide spacing is an advantage of the invention as compared to the prior art since now fewer carrier cross bars are required than heretofore.
  • the arrangement of the cross pieces in spaced relation to each other results in a substantial weight reduction and the construction requires less material than heretofore because due to the above described arrangement of the portions of the cross pieces relative to the axis of symmetry 40 there results a honey comb type of structure which is relatively light but nevertheless has substantial strength.
  • a honey comb type of gap strip may be, for example, manufactured in the following manner.
  • a single piece profile is first produced, for example by rolling or extruding.
  • the intermediate land or cross piece of the profile will have a height H as shown in FIG. 5.
  • the single piece profile will be cut along the lines 45, 46, 47, 48, to produce two separate pieces which are then shifted longitudinally relative to each other so that they may be connected'along lines 45, for example, by welding whereupon the height H of the cross connecting pieces will be substantially doubled.
  • Another possibility of completing the present gap strips would be to connect them along the axis of symmetry 40 by connecting means which, for example, may be loosened so as to provide the possibility of replacing the upper portion of the gap strip when it is worn out. This could, for example, be accomplished by threaded connecting means and straps 50.
  • This embodiment has substantial advantages with regard to assembling and disassembling the gap strips.

  • a glide piece or bearing block 44 which is firmly secured to the upper rod 32' but permits relative gliding movement between the carrier bar 42 and the gap strip 30. Similar considerations apply to the glide piece or bearing block 44 inserted between the lower rod 33 and the carrier bar 42.
  • the construction or embodiment which provides for a relative gliding movement between the carrier bars and the gap strips has the additional advantage that the width of the entire sealing device can be easily adapted to the local requirements simply by adding or removing gap strips and by exchanging the carrier bars either by longer or shorter bars. This adaptability is an important advantage of the invention.
  • the mounting or assembly is relatively simple. For example, it is possible to first place a bearing block of elastic position into position on the top edge of the cross carrier bar where it is to contact the respective gap strip. Thereafter the cross bar is inserted into the respective aperture of the gap strip and an additional bearing block is inserted between the lower edge of the cross bar and the lower portion of the gap strip. By forcing the second bearing block into position, automatically both bearing blocks are subjected to the desired biasing force, whereby the necessary firm connection is accomplished, especially since the established biasing force counteracts any shift of the gap strip relative to the cross bar.
  • an elastic body 51 inserted between the upper rods 32 and 32 of the gap strips 29 and 30.
  • This elastic body 51 as well as the respective elastic body 52 which is inserted between the lower rods 33 and 33' are so dimensioned and shaped that they are subjected to a biasing force, whereby not only a scaling is accomplished but the gap strips 29 and 30 are also supported laterally relative to each other in a resilient manner, whereby biasing forces are established which will continuously restore the gap strips to their normal evenly spaced positions.
  • FIG. 7 is a view on a slightly enlarged scale of a portion of FIG. 1 in order to illustrate that layers of glue 53 may be provided between the bearing blocks 14 and the glide pieces 15 as well as between the bearing blocks 14 and the gap strips 11.

  • gluing the bearing block 14 to the bar 6 may be omitted altogether.
  • the spring means 18 symbolically shown in FIG. 2 may, for example, comprise strips 55 of polyurethane as shown in FIG. 9. These strips may have a width slightly larger than the spacing between the adjacent gap strips 11 so as to press the strips 55 into the spacing, whereby the above described biasing force is provided.
  • FIGS. 10 and 11 illustrate modified embodiments for firmly interconnecting the gap strips with the bearing means.
