Definitions

  • the invention relates to manhole covers, which are arranged in the traffic area and can be driven over by vehicles. Above an open shaft, a frame element into which a cover element is inserted is usually present. Frame and cover elements are made either entirely of metal casting or as a composite metal casting with concrete.
  • the cover element inserted into the frame element rests on a bearing surface of the frame element, which is designed as a flange on the frame element.
  • the bearing surfaces of the frame and cover element are 'often formed from the metal casting.
  • the invention is based on the finding that the rattling noises occurring when driving over are at least not exclusively caused by a tilting of the cover element, but the cover element is displaced horizontally. The outer edge abuts against the inner edge of the frame element causing the rattling noises. the.
  • a manhole cover according to the invention as known from the prior art, is provided with an elastically deformable insert element.
  • the insert element is not only formed so that it is connected either to the cover element or the frame element and forms only a sound-damping pad, but the insert element is also a horizontal displacement of the cover element when overrunning prevent ble.
  • the cover element rests on a radially outer horizontally oriented flange of the frame element.
  • At least one elastically deformable insert element with a circular, partially circular, L-shaped, triangular, rectangular or trapezoidal cross-section is positively and non-positively attached to the flange or cover element, so that a region of the insert element between the support surface of the cover element and the support surface the flange is present, which keeps them in the unloaded state at a distance to each other.
  • an insert element can also have a combination of these mentioned cross-sectional shapes, so that at least two regions are present on an insert element, on each of which one of the previously designated cross-sectional shapes is present.
  • an area with a rectangular and another area with a triangular or part-circular cross-section may be present on one insert element.
  • correspondingly complementary grooves can then be formed, in each of which a corresponding outer contour exhibit- the part of an insert element engage and thereby form-fitting too large a shift and thus a striking of the lid member on the frame member is prevented when driving over.
  • the insert element rests with its radially inner side at least in regions on the cover element and with its radially outer side at least partially on the frame element.
  • the frame member and the lid member can be kept fixed against a horizontal displacement.
  • an insert element can be introduced into a groove formed on the underside of the cover element and additionally into an upwardly open groove formed in the flange of the frame element. It is held in such a form-fitting manner and prevents horizontal movement of the cover element when driving over, which would lead to striking the radially outer edge of the cover element to the radially inner edge of the frame member.
  • the insert element can rest with its side walls over the entire surface of the side walls of the groove and thereby an at least almost play-free fit can be achieved. This also facilitates insertion during insertion of the cover element into the frame element.
  • the radially outer side wall of the insert element on the frame member above the flange and the radially inner side wall of the insert member may rest against a radially outer wall portion of the lid member.
  • a shoulder may be formed at the lower radially outer edge of the cover element, which has a correspondingly reduced outer diameter.
  • the insert element should project beyond the radially outer edge of the cover element and rest against the radially inner wall of the frame element above the flange, so that the cover element can be supported on the frame element with the aid of the insert element.
  • the insert element projects beyond the cover element, so that at least in the unloaded state, no direct contact between metallic surfaces of the frame element and cover element can occur.

  • the abutment surface may also be chamfered at an angle to provide a vertically downwardly tapering cone, which facilitates insertion of the lid member upon insertion into the frame member and may improve fit with the insert member.
  • insert elements may be used as segments.
  • the segments may be formed part-circular and each such segment may be arranged in a region between two strainer pockets. But it is also possible to arrange several insert elements with different distances to the radially outer edge of the lid member. These can then form a ring arrangement in which the insert elements have different diameters.
  • the insert elements can, as described above, each be inserted into two grooves in the flange and cover element. However, it is also possible to use a combination of the embodiments already described.
  • the insert element with the largest diameter on the radially inner wall of the frame member and the radially outer edge of the lid member abut and at least one further insertion element with a smaller diameter in grooves formed on the flange and the lid member may be introduced.
  • an insert element use thereof with a circular cross-section.
  • this insert element can be accommodated in a groove, which is formed radially around the outer wall area and preferably around the cover element around the circumference. This insert element is then in touching contact with the radially inner region of the frame element above the flange. With a corresponding outer diameter and the dimensioning of the groove, a positive and non-positive retention of the insert element in the groove on the cover element can be achieved. After inserting the cover element into the frame element, the insert element can exert a compressive force against the frame element, which counteracts a horizontal displacement of the cover element when passing over in addition to the elasticity of the insert element.
  • insert elements are made of a suitable elastomer having a sufficient hardness and a corresponding damping, in addition wear on the contacting metallic surfaces of the frame and cover element can at least be reduced.

Abstract

La présente invention concerne des couvercles de regard qui sont placés dans une zone de trafic et sur lesquels peuvent rouler les véhicules. L'objet de l'invention est d'éviter, ou au moins de réduire considérablement, les bruits de claquement se produisant lors du passage des véhicules sur le couvercle de regards. Le couvercle de regard selon l'invention comporte un élément couvercle disposé dans un châssis et reposant sur une bride horizontale, radialement extérieure. Un élément rapporté, élastiquement déformable, présentant en coupe une forme circulaire, partiellement circulaire, triangulaire, en L, rectangulaire, trapézoïdale, ou une combinaison de ces formes, est fixé à la bride ou à l'élément couvercle par complémentarité de forme et/ou par assemblage à force, de façon qu'une zone de l'élément rapporté se trouvant entre la surface d'appui de l'élément couvercle et la surface d'appui de la bride maintienne, en l'absence de charge, un écartement entre ces surfaces. La face radialement intérieure de l'élément rapporté est adjacente au moins par endroits à l'élément couvercle, alors que sa face radialement extérieure est adjacente au moins par endroits au châssis, ce qui permet d'éviter le déplacement horizontal de l'élément couvercle par rapport au châssis.
