Definitions

  • the invention relates to a manhole cover frame according to the preamble of claim 1. Furthermore, the invention relates to a method for inserting such a manhole cover frame.
  • Such a manhole cover frame is sold, for example, under the name "Budaplan" by the applicant.
  • it is achieved by the tapered outer sides, that is to say by a conical design of the manhole cover frame, that forces acting vertically on the manhole cover frame are divided into vertical and horizontal components. This results in an oblique load transfer, so that a large proportion of force is derived in a surrounding road surface, resulting in a large discharge of the shaft structure.
  • a relatively large total support surface is available, so that a uniform pressure distribution takes place. A drop in the manhole cover frame is thus reliably prevented.
  • a method for installing such a manhole cover frame is made, for example EP 1 182 299 B1 known.
  • an annular opening with an oblique milling edge is formed with a round milling head, wherein the oblique milling edge has substantially the same angle to the vertical as the tapered outsides of the manhole frame.
  • DE 10 2006 056 936 A1 describes a method for installing a manhole cover and an associated manhole cover, wherein the manhole cover has a manhole cover frame which is formed substantially cylindrical, wherein at its upper end a circumferential collar is provided. At the manhole cover frame reinforcing elements are arranged radially on the outside, which direct vertically acting forces on a boundary surface of a conical milled recess opening. Between the manhole cover frame and a manhole structure, a filling or displacement body can be arranged, which on the one hand serves for level adaptation and on the other hand has elastic properties, so that vertical impacts on the manhole structure are damped.
  • a manhole cover in which no vertical forces are transmitted from the manhole cover frame to the manhole structure is over DE 10 2004 017 805 A1 known.
  • a guide ring is optionally placed with the interposition of height compensation rings on a shaft structure.
  • the guide ring serves to center a manhole cover frame radially with respect to the manhole structure.
  • the manhole cover frame is axially displaceable relative to the guide ring in the longitudinal direction.
  • the axial location of the manhole cover frame is defined by a base layer, a binder course, and optionally a topcoat applied above the level of the manhole structure.
  • the manhole cover frame thus floats, as it were, in the road surface, without any force being transmitted from the manhole cover frame to the guide ring and thus to the manhole structure.
  • the Budaplan system however, has the disadvantage that it must be adjusted relatively expensive compared to the road surface.
  • the manhole cover frame is aligned with the aid of level brackets opposite the road surface. With the help of grout the manhole cover frame is then connected to the manhole structure and the surrounding oblique cutting edges of the opening in the road surface.
  • the invention is based on the object to provide a manhole cover frame of the type mentioned, which can be adjusted without much effort, subsidence of the manhole cover frame allows and still has a high load capacity.
  • this object is achieved in that a manhole cover receptacle in a guide ring which has from an upper side to a lower side tapered outer sides and a cylindrical interior, is formed telescopic.
  • the guide ring can be arranged a bit below the road surface, for example, directly on the shaft structure, the compensation to the road surface is then carried out by the telescopically guided in the guide ring manhole cover.
  • the manhole cover receptacle is then usually aligned flush with the road surface and rolled into the asphalt layer.
  • the manhole cover then rests on the asphalt course with a collar.
  • the asphalt layer supporting itself on the conical guide ring can then pass the load acting on it over the guide ring into the surrounding layer (base course, antifreeze layer). As a result, lower to no loads on the shaft structure.
  • the manhole cover receptacle is advantageously guided axially displaceably in the interior with a cylindrical extension.
  • the cylindrical extension can be formed integrally with the manhole cover receptacle. In this case, the extension of the guide ring axially overlap relatively far, so that a good axial guidance is obtained.
  • the manhole cover receptacle on an outwardly facing, circumferential collar, wherein optionally the collar and the top are arranged at least partially parallel to each other.
  • the collar serves to connect the manhole cover receptacle with the top layer of a roadway.
  • the manhole cover receptacle is rolled into the roadway. Due to the parallel or slightly oblique arrangement of collar and top while good vertical forces can be transmitted from the collar to the top through the intermediate support layer. These are then disassembled into vertical and horizontal components by the tapered outsides of the conical guide ring. Due to the relatively small distance between the collar and the top is not to be feared that an uneven lowering of the manhole cover receptacle takes place. Rather, it can be assumed that the Aspahlt harsh between collar and top is sufficiently homogeneous and sustainable.
  • the upper side radially outwardly at least. extends as far as the collar. This ensures that all vertical forces acting on the collar forces are transmitted to the top of the conical guide ring, so that an oblique load transfer takes place through the guide ring.
  • the manhole cover frame can thus also be exposed to extreme loads.
  • the manhole cover receptacle on cast iron Cast iron is a commonly used material that is resistant to environmental influences yet relatively easy to work with.
  • the guide ring has a cylindrical core for guiding the extension.
  • the core can also be made, for example, relatively accurate, which in itself is not required for the guide ring.
  • the exact manufacture of the core has the advantage that precise guidance of the manhole cover receptacle can take place within the core.
  • the core has a radially outwardly directed flange and / or a radially inwardly directed flange at an end adjacent to the underside.
  • the radially outwardly directed flange serves to enlarge the connecting surface between the cylindrical core and the remaining guide ring. It allows a positive connection, so that in the usually expected forces peeling of the core is not expected.
  • the inward flange prevents the manhole cover receptacle from slipping too far into the core. It can also serve to hold dirt traps or the like, if they are not kept in the manhole cover receptacle.
  • the guide ring concrete and the core of cast iron are thus made of the same material as the manhole cover receptacle, so that a negative influence of the two materials by mutual contact is not to be feared.
  • the formation of the rest of the guide ring made of concrete has the advantage that concrete is relatively cheap and at the same time can absorb high forces.
  • the guide ring on its underside on a three-point support.
  • the three-point support enables a secure support of the guide ring on one.
  • Contact points grout can be introduced so that a positive connection between the shaft structure and the guide ring is obtained. This ensures a safe power transmission from the guide ring on the shaft structure.
  • an upper opening of the extension has a larger diameter than a lower opening.
  • the extension thus has a conical interior.
  • a manhole cover almost free of play, i. With a small annular gap, are held in the extension and thus in the manhole cover receptacle. Even when driving over the manhole cover with vehicles then no vibrations.
  • At least one radially inwardly projecting holding surface is arranged in the interior of the extension.
  • the support surface can be closed, for example, all around or have individual sections.
  • the holding surface serves e.g. to create a manhole cover, whereby its axial position relative to the manhole cover receptacle is defined.
  • the holding surface or an additional holding surface can also be used to hold, for example, a dirt collecting system.
  • stiffening ribs are arranged on a side facing away from the extension of the manhole cover receptacle. These ribs are thus on the bottom over the collar. This makes it possible to arrange the ribs below the road surface, the road surface then runs flat with the axial end of the collar. This results in a very secure and tight connection between the manhole cover receptacle and the road surface or the respective asphalt layer. This reliably prevents the penetration of, for example, water. Thus, the occurrence of frost damage is not to be feared.
  • the guide ring has an optionally radially outwardly projecting reinforcement.
  • the reinforcement serves on the one hand to make the concrete of the guide ring more resilient. At the same time forces can be introduced directly into a side surface of the opening, in which the manhole cover frame is inserted by the outwardly projecting reinforcement. The oblique load transfer is thereby improved.
  • the outwardly projecting reinforcement also allows a good, positive connection with the filled grout at the same time.
  • one or more annular grooves may be formed in the side surfaces.
  • the object is achieved by a method of the type mentioned above in that the manhole cover frame is inserted into a round, conical opening of a road surface, wherein in a first step, a coarse adjustment of the guide ring against the road surface takes place and in a second step, the manhole cover receptacle is inserted ,
  • the conical guide ring is first cast with grout and the manhole cover receptacle is then used, wherein between the top of the guide ring and the manhole cover asphalt is underpoured. So it is first the conical guide ring with the help of grout firmly connected to the shaft structure.
  • a complex adjustment of the guide ring with respect to the road surface is not required.
  • the heavy guide ring can be used and fastened relatively quickly.
  • the fine adjustment is then carried out by the relatively easy to handle manhole cover receptacle.
  • By relining between the top of the conical guide ring and the collar of the manhole cover receptacle is achieved that a good transfer of vertical forces from the collar of the manhole cover receptacle on the guide ring is possible.
  • a manhole cover frame 1 is shown having a guide ring 2 and a manhole cover 3.
  • the manhole cover receptacle is telescopic and tiltable guided in the guide ring 2.
  • a self-leveling manhole cover frame is obtained.
  • the conical guide ring 2 has an upper side 4 and a lower side 5, wherein these are connected to one another by tapering outer sides 6.
  • the guide ring 2 thus runs conically from its top 4 to the bottom 5.
  • the guide ring 2 has a cylindrical core 7 which extends through the entire axial length of the guide ring 2.
  • the cylindrical core has a radially outwardly directed flange 8.
  • the outwardly directed flange 8 serves to increase a contact area between the core 7 and the rest of the guide ring 2 and at the same time to allow a positive connection.
  • a radially inwardly projecting flange 9 is provided on the core 7.
  • This flange 9 prevents the manhole cover receptacle 3 can be inserted too far in the guide ring 2 and optionally jammed.
  • the flange 9 can also serve to obtain an enlarged bearing surface for the guide ring 2, or it can be used, for example, as a mudflap pad. In the present case, however, mud pockets 19 are formed.
  • the manhole cover receptacle 3 has a cylindrical extension 10, which is guided axially within the core 7. As a result, the radial position of the manhole cover receptacle 3 relative to the guide ring 2 is set relatively accurately, while an axial displacement remains possible.
  • the extension 10 is formed integrally with the manhole cover 3, as well as collar 11, which at an upper end of Manhole cover 3 are arranged.
  • the location details "above” and “below” always refer to the possible installation position of the manhole cover frame 1 in a roadway or to the illustration in FIG Fig. 1 ,
  • the collar 11 extends radially outward and has several tasks. First, it allows a support of the manhole cover receptacle 3 on the road surface so that the manhole cover receptacle 3 can be rolled. On the other hand, it allows the transmission of vertical forces on the top 4 of the guide ring 2, so that a one-sided sagging of the manhole cover receptacle 3 is not to be feared. The vertical forces are then decomposed by the oblique outer sides 6 of the guide ring 3 in horizontal and vertical components. By this oblique load transfer very high forces can be absorbed. The power transmission between the collar 11 and the guide ring 2 is only slightly impaired by the fact that there is no direct contact between the manhole cover 3 and the guide ring 2.
  • the force is transmitted only a relatively short distance between the collar 11 and the top 4 by a support layer, not shown.
  • the fact that in this case the top 4 extends even further radially outward than the collar 11, ensures that all forces exerted on the collar 11 can be transmitted to the guide ring 2.
  • An upper opening 12 of the extension 10 has a larger diameter than a lower opening 13.
  • the extension 10 in the interior 14 is thus formed conically, so to speak.
  • the extension 10 has in the interior a radially inwardly projecting retaining surface 15, which is not radially encircling in this embodiment, but only has a plurality of ring sections. It serves, for example, as a support for a manhole cover, not shown.
  • the guide ring is provided with a reinforcement 17 which projects radially outward.
  • two annular grooves 18 are introduced into the oblique outer sides 6.
  • the upper side 4 of the guide ring 2 extends radially further outward than the collar 11 of the manhole cover receptacle 3.
  • the manhole cover receptacle 3 has a corrugated surface in the region of the collar. This interface can also be used, for example, to record brand names or standard designations.
  • the ribbed surface also serves as slip protection.
  • Fig. 2 shows the manhole cover frame 1 with its peripheral collar 11 which projects beyond the stiffening ribs 16.
  • the stiffening ribs 16 can be arranged under a road surface, wherein the road surface is then flush with the circumferential collar 11. This creates a particularly secure connection.
