Definitions

  • the invention relates to a height-adjustable shaft closure. especially Sewer shaft termination, according to the preamble of claim 1.
  • shafts that provide access to the underlying channels or. offer similar facilities, formed by concrete rings. where the top ring is one Offers support for the manhole cover or manhole cover.
  • the height of the lid is determined by Intermediate rings made of concrete adapted to the road surface level. The intermediate rings are only in rough gradations available. which is why only a rough adjustment is possible. Resulting too high or too low manhole covers are on roads for Drivers are annoying and can e.g. even an obstacle for single-track vehicles and thus being dangerous. If the road surface is renewed, it must be readjusted the height of the manhole cover is required. This is a relatively labor intensive process.
  • CH 627 505 A5 describes a height-adjustable shaft end, whose mechanism consists of two concentric rings, the inner ring of which Duct cover picks up and rests on the outer ring. Between the outside and inner ring is helically arranged a toothing, which is a gradual Permits height adjustment of the manhole cover.
  • This construction can be used in existing Manhole closures can only be used with great effort. Beyond that is only a relatively small adjustment range possible.
  • US 3,629,981 A describes one height-adjustable manhole cover, consisting of a cylindrical element attached to the has a thread-like groove on the inside and a cylindrical sleeve with a thread-like structure on the outside complementary to the groove.
  • the sleeve has a flange for receiving the manhole cover.
  • the height of the shaft end can be varied. Sealing rings prevent this Penetration of dirt into the thread causes the arrangement to be elastically supported and prevent unwanted twisting.
  • the handling for height adjustment is relatively difficult since the sleeve. which can have a relatively large mass, twisted must become.
  • Other height-adjustable shaft closures are known from US 1 712 267 A AT 380 044 B and FR 2 523 615 A are known. These constructions are also not simply attachable to existing shaft systems.
  • the object of the invention is to provide measures which a Height adjustment of a manhole cover, manhole cover or the like in a simple and inexpensive manner infinitely or with a small step height while avoiding the disadvantages mentioned above enable.
  • the measures according to the invention are intended for both existing and new shaft closures may be applicable.
  • the object of the invention is achieved by the features of the characterizing part of claim 1. that the flange-like extension of the insert has the same shape as the upper end of the shaft, the construction can be applied to existing shaft ends using the original shaft or duct cover. It is only necessary to " interpose" the insert and the or each component between the manhole cover and the shaft.
  • the present invention can thus be used in a simple manner for existing shaft systems. By protruding the insert into the shaft, a higher adjustment range can be achieved compared to known systems.
  • the or each component that can be attached to the structures on the insert simplifies handling when adjusting the height of the shaft end.
  • the structures on the insert and the corresponding shapes on the or each component can have different shapes.
  • Sawtooth-shaped bulges and corresponding grooves on the or each component can be provided on the insert. Holes on the insert and bolt-shaped extensions on the or each component are also conceivable. with the help of which the or each component can be fixed to the insert at the desired height. The height is adjusted by lifting the insert out of the shaft, which or each component is attached to the insert at a corresponding height, and then lowering the insert with the or each component back into the shaft. There is usually a recess at the top of the shaft. on which the or each component rests securely and non-slip. The insert is thus held at a height which is defined by the attachment of the or each component to the structures on the insert. The step height is determined by the spacing of the structures in the vertical direction.
  • the system according to the invention can also be applied to manhole covers with, for example, a rectangular or square cross section.
  • the insert and each component are preferably made of cast iron. however, the use of other suitable materials is also possible.
  • the insert according to the invention is essentially tubular, so that a Access to the shaft or a free drain of e.g. Allow sewage in the sewer becomes.
  • the Invention of the or each component designed in a ring.
  • a ring-shaped Component can with appropriate design of the structures in use and the corresponding shapes on the component can be adjusted by rotation.
  • the structures are advantageously composed of a plurality of ones which run essentially horizontally Bulges and the formations on the or each component by a corresponding shaped groove formed. This construction variant is light and therefore inexpensive to manufacture.
  • the vertical distances of the essentially horizontal Structures between 1 mm and 10 mm, preferably 5 mm. This can be a legal Regulation, which provides an adjustability of less than 5 mm, must be met.
  • a stepless height adjustment can be achieved. That the structures on one cylindrical insert are formed by an external thread. Thus, by twisting of or each component can be adjusted in height.
  • the or each component is through a ring with an external thread appropriate internal thread. So the ring can be on the desired height on the insert rotated and this is inserted into the shaft. By Rotation of the ring relative to the insert can change the height of the manhole cover can be varied.
  • the ring-shaped component by two ring halves with a shape on their Inside is formed in the form of a groove corresponding to the external thread of the insert, the placement of the component on the insert can be facilitated, since this does not come from below must be screwed onto the insert, but immediately to the correct height from the outside can be put on.
  • the insert with the component is placed in the shaft used. is due to the existing recess at the top of the shaft of the component or the components are fixed and keep the insert in the correct position. With a component in The shape of a continuous ring is also used for smooth upper shaft ends possible. since the ring cannot slip sideways.
  • means for example plug pins or Wedges. provided which the or each annular component in front of the insert Secure twisting.
  • a sealing element preferably a sealing ring.
  • elastic material between the or each component and the upper shaft end, can Noise and vibrations, e.g. occur when a vehicle over the shaft or Manhole cover moves. be dampened.
  • manhole or Manhole cover and the insert are made in one piece.
  • the production can e.g. in a casting process.
  • a support ring or the like is advantageously around the upper end of the insert and between the insert and the support ring or the like. If necessary, a wedge ring or the like is arranged.
  • the Support ring prevents bulk goods or asphalt from sticking to the structures on the insert or damage and thus prevent height adjustment.
  • the insert can be used with the wedge ring are wedged with the support ring and rotation is prevented.
  • Shape of the support and wedge ring is not limited to the ring shape but can also be a other shape of the shaft cross section can be adapted.
  • the manhole cover 1 includes a manhole cover 1 or the like, which is normally placed on a pipe or the like forming shaft 2.
  • the pipe, which forms the shaft wall 3 is usually made of concrete.
  • At the top of the Pipe is usually a slightly conical recess 9 into which the corresponding Shaped manhole or manhole cover 1 or the like can be used.
  • Over the shaft 2 e.g. an access to the underlying sewer or cable duct or the like. enables or drains rainwater into the sewer.
  • Height adjustment of the manhole cover 1 below it protrudes into the shaft 2 Insert 4 provided. In the illustrated embodiment, this is cylindrical.
  • For Height adjustment of the manhole cover 1 or the like is a protruding into the manhole Insert 4 provided.
  • this insert 4 corresponds to the cylindrical shaft 2 is also cylindrical. But there are also others Forming possible, the insert 4 is advantageously tubular, so that a Access to the shaft 2 or a drain of the waste water into the channel through this is made possible.
  • the insert 4 has its shaft wall 3 facing side structures 5.
  • these structures 5 can have any shape to have. They have the task of attaching one or more components 6 to the insert 4, whereby the height of the manhole cover 1 is set.
  • The is particularly advantageous Formation of the structures in the form of an external thread on the insert 4. This allows in combination with an annular component 6 with an internal thread 7, accordingly the external thread 5 on the insert 4, a continuous adjustment of the height of the shaft or Duct cover 1.
  • the annular component 6 can also be in two halves be shared. This allows the two parts to the side at the desired height External thread 5 of the cylindrical insert 4 are attached and do not have to below by turning to the appropriate height. This makes it easier Application and thus saves time and money.
  • a divided ring 6 instead of the external thread 5 also arranged one above the other Bulges. such as. sawtooth-shaped rings can be provided.
  • the height adjustment of the manhole cover 1 or the like is not infinitely variable but with a minimal one Step height according to the vertical distance of the bulges or sawtooth Wrestling possible.
  • the insert 4 does not necessarily have to be cylindrical be. because in this case the height cannot be adjusted by turning the insert 4 compared to component 6, but by vertically displacing component 6 on the Outer wall of the insert 4.
  • Fig. 2 shows a side view of a slightly modified performance variant in cross section.
  • the shaft is formed by a pipe.
  • the insert 4. which protrudes into the shaft is held by the ring 6 at the appropriate height.
  • the manhole cover is used in a recess at the top of the insert 4.
  • the difference to that shown in Fig. 1 Construction is there. that above the tube forming the shaft 2 or the like
  • Use a support ring 10 is arranged. which the insert 4 or which on the insert 4 structures 5 in front of bulk material, e.g. Protect sand, earth or asphalt and one guaranteed safe function.
  • FIG. 3 shows this support ring 10 on an enlarged scale.
  • the wedge ring 11 which between the support ring 10 and the insert 4 can be pressed in, serves to insert the 4 in front to protect against unwanted twisting.
  • Wedge pieces or other means that prevent twisting are of course conceivable.
  • FIG. 4a and 4b schematically illustrate a construction variant for setting the Inclination of the manhole and manhole cover in two different positions.
  • the Component 6 in a manner known per se by one inclined to the horizontal Formed in the direction of the divided ring, the ring parts 6 ', 6 "being rotatable relative to one another.
  • the two ring parts 6 ', 6' ' are in a position in which the upper End face of the upper ring 6 'forms a horizontal surface.
  • 4b shows the maximum Inclination caused by a rotation of the ring part 6 'with respect to the ring part 6 "of 180 ° is achieved.
