Definitions
- the invention relates to a manhole cover, in particular on manholes and water inlets, which has a manhole frame which is supported at the upper end of the manhole wall and which is designed for mounting a cover or a grate and the position of which can be adjusted in height and angle for alignment to a certain level .
- Manhole covers, or the like, especially on streets, squares. used to cover manholes and water inlets are known in various designs and essentially have a shaft frame and a cover or a grate for completely or partially covering the shaft opening.
- the manhole frame When you first install the manhole cover, the manhole frame is installed flush with the floor surface. This is especially necessary on roads and places with vehicle traffic. If the surface has to be renewed or installed after a certain time, for example a road or surface covering, the original level of the surface can generally no longer be maintained. then it has to the shaft frame will be realigned again. This is a fairly complex work, which is undesirable not only because of the costs, but also because of the associated impairment of the flow of traffic. There have therefore been many proposals to reduce the work that has to be done to realign the shaft frame to a new street level.
- the manhole frame is constructed in two or more parts and consists essentially of a lower and an upper manhole frame, the latter being designed to receive a cover or a grate.
- the upper manhole frame can now be exchanged for other upper manhole frames of different heights, so that the alignment to the respective level can be achieved.
- various upper manhole frames have to be kept in stock and, if necessary, have to be machined to a desired size. This solution is also expensive, since the parts of the manhole frame are usually cast from ferrous metals.
- the upper manhole frame can be raised and lowered as desired with respect to the lower manhole frame by means of screw bolts, the cohesion between the two frame parts being achieved by brackets fastened to the upper frame part and carrying threaded bolts which lie against the underside of a flange arranged in the lower frame part.
- sleeves with an internal thread with a vertical axis are anchored to the upper edge of the shaft wall.
- Screw bolts are inserted into these, which extend through bores in the shaft frame and are equipped with a nut or an adjusting ring on the underside of the shaft frame.
- the manhole frame can be brought into any desired position by lowering or lifting and can also be secured.
- the space between the upper edge of the shaft wall and the shaft frame is then filled in with mortar.
- hooking means distributed over the circumference are arranged on the inner wall of the shaft frame and the upper end of the shaft wall, which serve to fasten a device for adjusting the height of the shaft frame.
- the invention also includes a device for adjusting the height of the manhole frame of the manhole cover according to the invention, with which the manhole frame can be raised and lowered in an optimal manner.
- a device which has two connecting arms which are intended to be connected to a hooking means arranged on the shaft frame and at the upper end of the shaft wall, the connecting arms being connected to one another by a length adjustment device.
- the length adjustment device can expediently be a threaded bolt on which the connecting arms are screwed or loosely guided, between which an adjusting ring is arranged on the threaded bolt.
- Fig. 1 shows the upper end of a shaft 2 laid with a vertical axis 1, e.g. a manhole or a water inlet.
- a vertical axis 1, e.g. a manhole or a water inlet.
- the shaft wall is designated. This can be made of in-situ concrete or consist of a concrete base or frame.
- On the inner wall 4 of the shaft 2 some sleeves 5 are anchored distributed around the circumference, which are described in more detail with reference to FIG. 3.
- a manhole frame 6 is laid flush with a bottom surface 7, which is usually formed by a covering 8. Between the manhole frame 6 and the manhole wall 3, a mortar 9 is placed on which the manhole frame 6 rests.
- the shaft frame 6 also has sleeves 10 on its lower edge, which lie opposite the sleeves 5 in the shaft wall 3 and are made in one piece with the shaft frame 6.
- the sleeve 5 has a recess 11 on the sleeve wall directed against the shaft frame 6.
- the recess 11 is a slot which serves to receive a threaded bolt 12.
- a recess 13 corresponding to the recess 11 in the sleeve 5 is provided in the wall of the sleeve 10 directed against the sleeve 5, a recess 13 corresponding to the recess 11 in the sleeve 5 is provided.
- the manhole frame 6 can by means of the thread bolt 12 and a threaded nut 14 are firmly clamped to the mortar 19.
- the shaft frame 6 has a truncated cone-shaped wall 15, which forms a flange 16 at its lower end, the end face of which forms the inner wall 17 of the shaft frame 6 and is essentially flush with the inner wall 4 of the shaft 2, which surrounds a cover or grate (not shown) ).
- the sleeves 10 are integrated in the flange 16.
- the flange 16 has two downwardly directed ring webs 18, 19, in which the sleeve 10 is embedded.
- the sleeve 10 has an insertion opening 20 which has a rectangular cross section.
- the insertion opening 20 has a longitudinal axis 21 which extends transversely to the shaft axis 1, preferably perpendicularly and radially.
- 3 shows details of the sleeves 5 anchored in the shaft wall 3.
- the sleeve 5 has an insertion opening 22 corresponding to the insertion opening 20.
- a height adjustment device 28 is used in order to bring the manhole frame 6 into the new position.
- a height adjustment device 28 is used.
- several height adjustment devices 28 of this type are used in accordance with the number of sleeves 5, 10 distributed on the circumference.
- This consists of a threaded bolt 29 with a screw head 30 which is connected on the thread side to a support disk 31 which is spherically curved on the side facing away from the screw head.
- a lower connecting arm 32 is screwed onto the threaded bolt 29, while an upper connecting arm 33 with a through hole 34 is loosely guided on the threaded bolt 29.
- the lower connecting arm 32 has an insertion part 35 corresponding to the insertion opening 22, while the upper connecting arm 33 has an insertion part 36 corresponding to the insertion opening 20 of the sleeve 10.
- An adjusting ring 37 is clamped on the threaded bolt between the two connecting arms 32, 33.
- the adjusting ring 37 is expediently designed as a slotted ring screwed onto the thread of the threaded bolt 29, a tensioning screw 38 being arranged in the ring parts in the region of the slot, with which these ring parts can be drawn together or driven apart.
- the adjusting ring is clamped on the threaded bolt 29 with the clamping screw 38, it forms a shoulder which is firmly connected to the threaded bolt 29 and, when the threaded bolt 29 is turned, lies on the underside of the upper connecting arm 33 and lifts the latter and thus also the manhole frame 6
- the shaft frame can be raised over the entire circumference, the lifting being able to take place both uniformly or, as with an inclined surface 27, differently. If the manhole frame has taken its new place, the space between the manhole frame 6 and the manhole wall 3 is included filled in with a mortar. It is expedient here - not specifically shown in FIG.
- the adjusting ring 37 as can be seen from FIG. 4, also has a spherically curved side surface.
- the height adjustment device or height adjustment devices 28 can be removed and are available as often as desired for further laying or for laying other manhole covers.
- the sleeves 5 in the shaft wall 3 can also be arranged in a coherent ring if, for example in the case of very large shaft covers, a more effective anchoring of the sleeves 5 is required.
- the threaded bolt 29 can be adjusted by a stroke adjustment, e.g. hydraulic or pneumatic type, to be replaced.
- the threaded spindle can also be rotated by means of a motor drive.
- other hooking means can also be provided instead of the insertion openings 20, 22, for example cams on which the connecting arms 32, 33 are supported. Such cams need only protrude little over the profile of the inner wall of the shaft.
