Definitions
- the invention relates to a manhole cover, which is used in particular to cover manholes in traffic areas.
- the manhole cover consists of a manhole cover, a cast iron body with or without concrete filling and a frame made of cast iron or cast iron and concrete.
- Manhole covers are known in which the circumferential bearing surface for the manhole cover located on the frame is repeatedly interrupted by cutouts. These recesses serve to accommodate Tragnokken arranged on strainer inserts.
- damping inserts which are incorporated into the manhole cover and / or the frame.
- the invention is therefore based on the object of providing a manhole cover which can be produced cost-effectively and which both enables simple and safe arrangement of dirt traps and also ensures a reliably damping or sealing support of the manhole cover in the frame.
- the particular advantage of the invention is that a secure mounting of the mudflap is ensured by the continuous circumferential support surface for the manhole cover arranged in the frame and the support plane arranged underneath for receiving a mud flap without breaking through the mating surface for the manhole cover.
- This makes it possible to introduce at least one continuous circumferential groove into the support surface and to arrange a damping insert therein. When the damping insert is moved in the longitudinal direction, for example by periodic mechanical action via the manhole cover, it can no longer slip out of the groove.
- Another advantage is that only a single damping insert of a suitable length has to be inserted according to the length of the continuous groove and not a large number of such damping inserts.
- An additional advantage of the invention results from the fact that, in addition to or instead of the circumferential groove for receiving the damping insert, a continuous circumferential recess for receiving a sealing ring is arranged behind the bearing surface. The sealing ring is pressed into the recess and is therefore not pulled out when the manhole cover is removed.
- manhole cover is also suitable as a cover for cut-off switches and other special designs.
- cast eyes are attached to the manhole cover and the frame, into which openings are made for screwing the frame to the manhole cover and / or the frame and manhole base.
- recesses are optionally left open, which make it easier to clean the openings if they are dirty after installing the manhole cover.
- the continuous manhole cover contact surface also allows the incorporation of all-round metallic Sealing surfaces with a raised edge towards the inside of the shaft. These so-called sand closures can either be conical or concentric.
- the cut-outs for the anti-rotation cams can be enlarged in such a way that openings for the insertion of a boarding aid, preferably a correspondingly prepared operating key, can be made. The opening is covered by the anti-rotation cams and thus protected against contamination.
- the manhole cover consists of a manhole cover 1 and a frame 2.
- the frame 2 has a continuous circumferential bearing surface 3 for receiving the manhole cover 1.
- a continuous groove 4 is machined into the support surface 3 by means of mechanical processing machines.
- the groove 4 is dovetail-shaped and serves to receive a damping insert. Due to the dovetail shape of the groove, the cushioning insert, which is made of elastic material, kept safe. Because the contact surface 3 is not interrupted, the damping insert cannot slide out of the groove 4 in the event of displacements in the longitudinal direction.
- a continuous circumferential recess 6 is arranged, which serves to receive a sealing ring.
- 1 to 5 show an embodiment in which both the groove 4 and the recess 6 are present.
- 6 to 10 an embodiment is shown, which has only the recess 6 and is used especially with screwable manhole covers.
- the sealing ring is a rubber round cord ring. The use of rubber profiles is also possible. Depending on the respective requirements, additional sealing materials can also be used.
- the frame 2 has a support plane 7 below the support surface 3, which serves to accommodate a dirt trap.
- the support plane 7 is designed as a continuous circumferential casting edge. It is also possible to arrange only appropriately distributed cast edge segments. The support of the dirt trap in the frame 2 is thus realized without any intervention in the support surface 3 of the manhole cover 1.
- manhole cover 1 backflow-proof or gas-tight embodiments of the manhole cover are on Manhole cover 1 and cast eyes 8 are arranged on the frame 2, as can be seen in FIG. 7, in which openings 9, in the present exemplary embodiment bores, are located. Through this opening 9, a screwing of the frame 2 to the manhole cover 1 and / or of the frame 2 and the manhole base is possible. As shown in FIG. 8, cutouts 10 are left open on the frame 2 towards the inside of the shaft, which make it easier to clean the opening 9 when it is dirty after the shaft cover has been installed.
- the continuous circumferential bearing surface 3 has a subsequently incorporated metallic sealing surface which has a raised edge towards the inside of the shaft. In this way, a so-called sand seal is realized.
- the metallic sealing surfaces can be tapered or concentric.
- the cutouts 11 for the anti-rotation cams with openings for receiving a boarding aid, for example a correspondingly designed operating key, can be provided for shaft covers with a clear width greater than 650 mm.
- the opening is covered by the anti-rotation cams of the manhole cover 1 and thus protected against contamination.
