Definitions

  • the invention relates to the upper part of a road gully.
  • a cover forms the walkable or drivable part of the street gully which is surrounded by a traffic area, for example a sidewalk, a bicycle path or a roadway, and which has openings through which the surface water can flow into the street gully.
  • a traffic area for example a sidewalk, a bicycle path or a roadway
  • an element for example a sidewalk, a bicycle path or a roadway
  • the drain pipe runs upright and directs the inflowing water into a horizontal canal of the sewer system.
  • the drain pipe usually has a circular cross section.
  • a connector is usually arranged, which on the one hand connects to the drainpipe and on the other hand is adapted in terms of shape - for example rectangular - and dimensions to the upper part of the road gully in such a way that the upper part can be mounted on or in the connector.
  • the traffic area does not run in an ideal horizontal plane; b. in the case of a cambered road surface - and / or an incline, i.e. an angle in the longitudinal direction that deviates from the horizontal.
  • upper parts known from practice allow an angle compensation between the for example vertical drainage pipe and the cover, so that the cover can be aligned with the desired inclination and slope.
  • the invention is based on the object of specifying an upper part of a road gully which enables its upper side to be aligned as precisely as possible in adaptation to the surface of the traffic area, is easy to install and cannot move, and is inexpensive to provide.
  • the invention is also based on the object of providing a compensating plate and a set of compensating plates which enable such an upper part to be created.
  • the invention proposes determining the distance between the connection piece and the support with the aid of one or more compensating plates made of plastic.
  • the compensating plates made of concrete are known from practice, which, however, under the influence of water - especially in Combination with road salt - prone to severe corrosion.
  • the compensating plates according to the invention consist of a plastic.
  • the compensating plates can be manufactured using an injection molding process, and to increase their mechanical load-bearing capacity, they can have reinforcing fibers such as, for example, a proportion of glass fibers.
  • the compensating plates are also simply referred to as plates for short. Due to their material properties, the panels can have an acoustic dampening effect and help to avoid or minimize rattling noises that could be caused when driving over the gully.
  • the fitting In the case of a vertically oriented drainage pipe, the fitting typically provides a horizontally oriented surface on which the top of the road gully can be mounted.
  • the adaptation to the respective inclination and incline of the traffic area can therefore take place with the compensating plates if they have a wedge-shaped cross-section in a first direction and possibly also transversely thereto.
  • only compensating plates can be used, each of which has a wedge-shaped cross-section in only one direction, two different types of compensating plates are provided, namely on the one hand with a wedge-shaped cross section in the first direction and on the other hand with a wedge-shaped cross section in the transverse direction.
  • the plates can be designed, for example, rectangular. So they have a length that is greater than their width and thus have a longitudinal direction and a transverse direction in which they are installed on site. In this case, it is not absolutely necessary for the plates to be longitudinally in the longitudinal direction the traffic area, for example a street, must be built, rather the plates can also be arranged in such a way that their longitudinal direction runs transversely to the longitudinal direction of the street.
  • the compensation plates can be used, which are only mounted in a correspondingly different orientation. This is economically advantageous since compensating plates do not have to be provided, each of which is only provided specifically for inclination compensation in the longitudinal direction or specifically for inclination compensation in the transverse direction of the road.
  • the slabs Due to their wedge-shaped cross-section, the slabs have a decreasing or increasing thickness in the longitudinal or transverse direction, the difference in thickness to compensate for, for example, 0.5 cm, 1.0 cm, 1.5 cm or 2.0 cm slope or inclination serves accordingly is large.
  • the compensating plates according to the invention can be used in particular for a so-called fine height adjustment, because in comparison to the concrete plates known in practice, the plastic plates can advantageously be made thin, while mineral compensating plates tend to tear below a certain minimum thickness.
  • the plastic material used is free of recyclate and that the plastic material also contains reinforcing fibers in order to ensure that the comparatively thin compensating plate can withstand high mechanical loads, even in view of the low material thickness where the compensation plate has its lowest material thickness - to ensure.
  • a traffic area When a traffic area is being rebuilt or repaired, its surface is finished after the sewer shaft has been created and also after the connection piece has been mounted on top of the sewer shaft.
  • the manhole cover In order to be able to adapt the manhole cover as flush as possible to the finished surface, e.g. a road surface, in some cases no adjustment to a specific gradient in the longitudinal or transverse direction of the roadway is required, but only a height adjustment.
  • compensating plates designed according to the proposal do not necessarily have to have a wedge-shaped cross section, but can also be designed as pure spacer plates that are only used to overcome or compensate for a difference in height.
  • the compensating plates are provided in different material thicknesses. Due to the different thicknesses, combinations of two or more plates, different stacks of plates can be created, which have different overall heights in a fine gradation.
  • the different material thicknesses of the compensating plates do not always represent an integral multiple of the material thickness of the thinnest compensating plate. In this way, through appropriate combinations of the compensating plates, finely graduated intermediate steps in the total thickness of the plate stack can be achieved. For example, instead of three compensating plates of different thicknesses with a material thickness of 5, 10 and 15 mm, the plates with material thicknesses of 4, 6 and 10 mm can be produced so that stacks of plates with a total thickness of 4 to 20 mm in fine increments of 2 mm increments can be generated.
  • a set of compensating plates in different material thicknesses can advantageously be put together. This enables combinations of compensating plates, which enable the production of spacer elements of different heights in very small increments.
  • the plates can - in particular close to the edge - be designed with cutouts, e.g. with a grid pattern, the grid having holes which partially or fully penetrate the plate thickness.
  • this configuration is particularly economical in terms of material and is therefore economically advantageous.
  • Thirdly, this configuration is also advantageous from a technical point of view, because this configuration offers a manufacturing advantage in injection molding, especially with thin plastic sheets, and can effectively prevent so-called sink marks, as can occur with full sheet casting without perforations.
  • sink marks have a negative effect on the dimensional stability of the plates, since they warp when or after they are removed from the mold and lose their flat contact surfaces in the process.
  • the recesses also enable the compensating plates to be fastened in an optimal manner, in that the compensating plates can be filled with mortar, a synthetic resin or the like.
  • the panels can be glued to the subsurface and, moreover, also be fixed in a form-fitting and non-shifting manner by the mortar mass that has penetrated into the recesses and then hardens.
  • the plates can have support pins that penetrate almost the entire or the entire thickness of the plastic plate and allow a highly resilient load transfer in the vertical direction.
  • the support pins can be cast directly into the plate when the compensating plate is manufactured, or the plastic material can be encased in it.
  • provision can also be made to provide openings in the compensating plate, so that the support pins are subsequently inserted into the plate.
  • comparatively short support pins can be inserted into the individual panels in accordance with the material thickness of the respective plate, so that when a number of compensating plates are arranged one above the other, the load is transferred by the several support pins arranged one above the other.
  • the support pins are only inserted into the openings at the construction site, so that not only the desired load transfer takes place over the entire height of the stack of panels, but the compensating panels of this stack are also connected to one another so that they cannot move.
  • the recesses already mentioned above for example in In the form of a grid pattern, to be cast with a material, for example with the already mentioned resin or mortar, which has a high compressive strength after setting or hardening, whereby the compressive strength of the panels can also be increased and a high load transfer is made possible.
  • Fig. 1 shows a rectangular compensating plate 1, which borders an inner free space 2 like a frame and is provided with a large number of recesses 3, so that the compensating plate 1 is designed in the form of a grid, in which the recesses 3 are designed as openings which the compensating plate 1 over enforce their entire material thickness.
  • Fig. 2 shows a plan view of a second embodiment of a compensating plate 1, which, in contrast to the embodiment of FIG Fig. 1 Has stacking feet 4.
  • the stacking feet 4 make it possible on the one hand to mount the compensating plate 1 so that it cannot move, for example by inserting it into a layer of a hardening material such as mortar, synthetic resin or the like, or by placing it on a connection piece, which in turn has recesses that are used for Serve to accommodate the stacking feet 4.
  • the designation as Stacking feet stems from the fact that on the top of the compensating plate 1 above the stacking feet 4 depressions are arranged, which serve to hold the stacking feet 4 of a compensating plate 1, so that several compensating plates 1 can be stacked one on top of the other. By means of the form fit, which is achieved via the stacking feet 4, each upper compensating plate 1 is also held in the compensating plate 1 underneath so that it cannot move.
  • the ones in the Fig. 2 , Fig. 5 and Fig. 6 The plates shown in the drawings have, as can be seen from the drawings, a transverse slope, that is, a difference in thickness in their transverse direction.
  • the minimum thickness is 6 mm, and the wedge shape results in a slope or incline of 1%.
  • the minimum thickness is also 6 mm, and the wedge shape causes a slope or incline of 4.17%.
  • the minimum thickness is also 6 mm, and the wedge shape results in a slope or incline of 2%.
  • the Fig. 3 and 4th show compensation plates that are only used for height adjustment, but not for slope or slope compensation. Accordingly, these compensating plates have a wedge-shaped cross-section neither in their longitudinal direction nor in their transverse direction.
  • the material thickness i.e. the thickness of the compensating plate
  • the material thickness is 6 mm.
  • Fig. 7 shows an embodiment of a compensating plate 1, which on the one hand has stacking feet 4 like the embodiments of FIG Figures 2 to 6 .
  • some of the recesses 3 are circular, as is also the case in the exemplary embodiment of FIG Fig. 1 the case is.
  • These circular recesses 3 are referred to as receiving openings 5, since they serve to enable support pins to be inserted into these receiving openings 5.
  • the support pins are made of a particularly pressure-resistant material, for example steel, so that excellent load transfer is made possible.
  • the receiving openings 5 are designed as breakthroughs so that the support pins can extend through several compensating plates.
  • the support pins are only as thick as the compensation plate 1, so that, for example, each compensation plate 1 can be provided with support pins by the manufacturer and the different, pre-assembled compensation plates 1 can be arranged one above the other at the construction site.
  • Inwardly protruding into the receiving opening 5 projections, for example in the form of small ribs, can serve to clamp the support pin located in the receiving opening 5 and to hold it securely.
  • the receiving openings 5 are only designed as troughs in order to receive a support pin in them in a captive manner, so that in this case the support pins cannot extend over several compensating plates.
  • the circular recesses 3 are provided as receiving openings 5.
  • This enables a particularly inexpensive design of the support pins with a likewise circular cross-section, so that, for example, a commercially available semi-finished product, for example steel rods, can be used and suitably cut to length in order to form support pins.
  • the diameter of the circular recesses 3, which are to be used as the receiving opening and 5 can be selected in adaptation to commercially available materials, for example in adaptation to commercially available round steel bars.
  • any other cutouts 3 can also serve to accommodate support pins.
  • the shape of the support pins and the recesses 3 are advantageously coordinated with one another in order to avoid inclinations, displacements or similar displacements of the support pins exclude within its recess 3.
  • the design of the recesses 3, which are to be used as receiving openings 5, in adaptation to commercially available materials that can be used as support pins is therefore economically advantageous since it does not require the production of specially shaped objects specially produced as support pins.
