Definitions

  • the invention relates to a connection of a built-in part used in a roadworks to a road surface surrounding the roadworks wear layer, the built-in part has an upper boundary which lies in a plane with an upper end of the wear layer of the road surface and with its edge to the wear layer of the road surface is connected with a layer consisting of an elastic mass, which adjoins the wearing surface of the road surface with its outer edge facing away from the outer surface and with its inner edge opposite the outer edge of the insert and which has a cross-section, the solid adhesion both having on the mounting part and on the wear layer of the road surface and on a bearing the wear layer foundation of the road surface.
  • connections of a fitting to a road surface are usually made in such a way that the road surface is brought up to the mounting part and fixed to the mounting part. Irrespective of whether the road has a wearing course with a road surface made of asphalt or concrete, damage must be expected within the vicinity of the built-in part which results from loads caused by passing traffic.
  • the built-in parts such as manhole frame
  • the built-in parts very often consist of materials whose thermal expansion coefficient differs significantly from that of the adjacent road surface.
  • damage in the area of the built-in component due to thermal stresses must be expected.
  • water such as rainwater, penetrates. This freezes in the winter. The ice increases the cracks and crevices in the vicinity of the fixture, so repairs must be made necessary to avoid significant road damage.
  • the object of the present invention is therefore to specify a connection for a built-in part to a road surface, with the aid of which such damage in the area of the road surface is avoided.
  • the elastic mass consists of an elastic base substance, which is formed as a mixture of elastic chips and a binder connecting the individual chips together, which forms a viscous compound with the chips together with an admixed granular material , which forms a viscous mass in the hot area and retains its elasticity in the cooled state.
  • Such an elastic mass is able to compensate for any type of stress that may build up between the fixture and the road surface, for example, due to differential thermal expansion and also due to deformations caused by the road traffic developed over the road.
  • the connection consisting of this elastic material has the decisive advantage that deformations of the yielding road construction material resulting from external stresses elastically regress, so that no cracks and gaps can form between the rigid installation part and the yielding road construction material.
  • the fixed connection of the elastic material to the rigid built-in component is retained, so that the connection of the elastic material to the installation part is retained if deformations occur repeatedly.
  • connection further has the advantage that due to the elasticity of the elastic mass thermal stresses between the parts to be joined together are avoided.
  • the layer consisting of the elastic material absorbs thermal expansions and contractions, without causing cracks or gaps in the elastic layer.
  • a ring made of the elastic material firmly adheres to the foundation provided between the fitting and the road surface.
  • This foundation may consist of stones, earth, asphalt and / or concrete, in which the built-in part is inserted.
  • the elastic material adheres very intensively to these, so that the connection is maintained under load.
  • These concrete surfaces can be formed for example by a guide, in the a manhole frame is inserted, which protrudes upward from the guide. As a result, the guide forms an edge design surrounding the manhole frame, on which the elastic material adheres excellently.
  • the elasticity of the elastic mass is generated by the fact that it consists of elastic chips that do not lose their elasticity, even by high loads. These chips can be created, for example, by shredding discarded rubber tires.
  • the elasticity of the mass is also achieved in that the elastic chips are wrapped and bonded together by a binder, which in turn unfolds high binding forces and moreover has elastic properties.
  • grainy material is added to the elastic ground substance of chips and binder. This can for example consist of grit, sand, granules of polymers and steel fabric.
  • the viscous in the heated state mass is pourable into molds, which is fitted in the cooled state between at least two mutually movable parts and dampens the movements of the parts.
  • the forms form a firm connection to the parts by heating their contact surfaces bearing against the parts, which remains in the cooled state and forms an elastic connection with the parts.
  • the molds can be properly and carefully installed at a specific position to dampen movement and connected by heating to the existing surfaces. Such connections are immovable in movements of the items.
  • an existing of the elastic mass ring encloses with its inner edge a manhole frame and is connected to this waterproof, and with its outer edge it connects to the wear layer of the road surface firmly and waterproof to and with its between the inner and the outer edge extending bottom part of the ring is mounted on an upper end edge of a guide member in which the manhole frame is guided.
  • the elastic ring has particularly far-reaching benefits for the rehabilitation of road surfaces. It avoids the occurrence of cracks and crevices in the area of the materials used, which, like the steel manhole frame, the existing concrete guide and the paved road surface, have very different thermal expansions and develop different connection forces when connecting to the elastic material.
  • the elastic ring has a cross-section, the height of which corresponds to a distance which holds a top edge bounding the guide part of an upper boundary of the manhole frame, which protrudes from the guide member. In this way, a continuous connection of the road surface is created to the manhole frame with the elastic material.
  • an arbitrarily shaped built-in part is connected to the inserted into a road structure elastic mass from which protrudes the fitting only in the region of its upper limit and otherwise firmly and watertight connected to the road surface by means of the elastic mass.
  • an arbitrarily shaped built-in part can be connected to a road structure with the help of the elastic mass, without causing tensions between the built-in part and the road surface, which leads to cracks or crevices within the road surface.
  • the use of the elastic mass prevents the different strains from causing damage to the road surface.
  • the additional waterproof connection prevents rainwater from penetrating the road surface and destroying it.
  • a trained as a rail fitting is connected along their mutually parallel lateral flanks to the elastic mass and connecting the side edges together rail head protrudes from the elastic mass.
  • thermal expansion due to temperature changes play a very important role, so that normally rails are not inserted into a road surface.
  • elastic mass in the boundary region between the rail on the one hand and the road surface on the other hand a seamless connection of the rail to the road surface is possible without the risk in the case of different thermal expansion that the road surface by columns or Cracks will leak.
  • the adhesion of the elastic mass to both the rail and the road surface is so intense that no cracks or crevices can form in the boundary area.
  • the rail is connected to the elastic mass along its rail foot which delimits the rail head at its lower end.
  • an elastic connection of the road body or any surface body to the rail foot is made possible also in the region of the rail foot.
  • the rail has a fixed support in the region of the road body or sheet.
  • two mutually parallel rails are interconnected by transverse connectors which extend through the elastic mass.
  • the mutually parallel rails including their cross-connector represent a structural unit that can execute expansions within the road body, without causing damage to the road body.
  • the connection of the rails to a surrounding road surface can be carried out easily.
  • installation parts 2, 3, for example in the form of manhole frame 4 or road inlets 5 must be installed.
  • asphalt road 1 is subjected to greater stress than a steel relatively rigid installation part 2, 3, for example, a manhole frame 4 or 1, due to vibration loads emanating from a traffic unwound on road 1 Road run-in 5.
  • a steel relatively rigid installation part 2, 3, for example, a manhole frame 4 or 1 due to vibration loads emanating from a traffic unwound on road 1 Road run-in 5.
  • the expansive due to the load asphalt strikes the relatively rigid mounting parts 2, 3.
  • the asphalt is heavily loaded mechanically, so that there is a risk that it will be destroyed due to this load.
  • There are cracks in the asphalt which can lead to considerable damage on the road 1 under the influence of water and frost.
  • a connection 6 consists of an elastic mass 7.
  • This connection 6 surrounds the installation part 2, 3 in the form of a ring 8.
  • This elastic mass 7 consists of an elastic base substance, which is a mixture 9 of elastic chips 10 and a binder 11 connecting the individual elastic chips 10 is formed.
  • This binder 11 combines with the elastic chips 10 and forms a viscous mass in the hot region, which is dimensionally stable in the cooled state according to a selected shape and retains its elasticity.
  • the elastic mass 7 is also granular material 48, which is incorporated into the elastic base material of chips 10 and binder 11 and this gives a high dimensional stability. As granular material 48 come into consideration grit, sand, granules of polymer and steel fabric. This granular material 48 is vigorously mixed with the elastic ground substance.
  • this viscous mass 7 can be poured from a vessel, such as a bucket 13, at a point between two surfaces of different elasticity, for example, between the road 1 and the built-in parts 2, 3. At this point, the viscous mass cools relatively fast and forms a connection between the parts of different elasticity.
  • This elastic mass 7 is waterproof by virtue of the chips 10 connected to one another by the binder 11.
  • the granular material 48 provides the necessary dimensional stability. It connects to the adjacent materials of the road 1 on the one hand and the built-in parts 2, 3 on the other waterproof so that no moisture can penetrate between these different materials.
  • This elastic connection is also achieved when a ring 8 is made of the viscous mass 7, which adjoins with its inner edge 14 on the mounting part 2, 3 and with its outer edge to an adjacent edge 16 of a road surface 27 forming wear layer 37.
  • a ring 8 is made of the viscous mass 7, which adjoins with its inner edge 14 on the mounting part 2, 3 and with its outer edge to an adjacent edge 16 of a road surface 27 forming wear layer 37.
  • the viscous mass 7 is so soft that they penetrate into the pores of the respectively adjacent substances 1; 2, 3 can penetrate and finds a firm hold on this.
  • the manhole frame 4 ends with its upper limit 26 at a predetermined level of a road surface 27. Below this level is an upper end 28 of the guide 19. In the region of a distance which lies between the road surface 27 and the upper end 28 of the guide 19, the elastic mass 7 is introduced either as a prefabricated ring 8 or in the hot viscous state. In this way, this connection 6 is elastic, so that damage in the region of this connection, for example, can not occur due to cracks.
  • the guide 19 is provided with a conically extending in the direction of the shaft 22 outer wall 29.
  • a wedge-shaped intermediate space 30, which is filled with the elastic mass 7, is formed in the region of this outer wall 29.
  • This elastic mass 7 supports, on the one hand, the guide 19 in a shaft structure 22 located above the shaft 22 and, on the other hand, makes it possible to compensate for stresses that may build up due to different heating of the guide 19 and the road 1.
  • a road drain 5 is elastically supported within the road 1 by means of the terminal 6, which surrounds a grate support 32 in the form of a ring 33. Also in the case of this grate support 32 different thermal stresses are compensated by the terminal 6.
  • the grate carrier 32 is mounted in a provided with conical side walls 35 guide 34. This guide 34 is elastically mounted in a corresponding road structure 36 by using the elastic mass 7.
  • each built-in part 2, 3 is connected to the elastic mass 7, which is introduced into a road structure 31.
  • This elastic mass 7 is formed on lateral boundaries of each built-in fitting 2, 3, so that only the upper limit 38 protrudes from the elastic mass 7.
  • the rest of the fitting 2, 3 is connected by means of the elastic mass firmly to the road surface 27 and optionally a foundation 39 of the road 1.
  • a rail 40 extend through the road 1, at the mutually parallel lateral flanks of the elastic mass 7 is formed.
  • a rail head 43 interconnecting the two flanks 41, 42 projects out of the elastic mass 7.
  • the rail 40 may also be formed with its the rail head 43 opposite rail 44 in the elastic mass 7 to occurring stresses in the lower part of the road structure 36 to prevent. Due to the fixed insertion of the rail 40 in the elastic mass 7, the rail 40 is firmly anchored in the roadworks 36. If, for example, two parallel rails 45, 46 are needed to guide a rail vehicle, they can be laid in a correspondingly large-dimensioned road construction 36, which is filled with elastic mass 7. In this way, the elastic mass 7 also surrounds connecting struts 47, which hold the two mutually parallel rails 45, 46 at a predetermined distance.
