Definitions
- the invention relates to a method for producing a damped manhole cover by finally storing a closing piece in a frame, such as a manhole cover in a manhole frame of a manhole cover, a steaming intermediate layer being inserted between the closing piece and the frame and one Manhole cover with accessories for performing the procedure.
- the object of the invention is therefore to produce a damped manhole cover in such a way that the disadvantages mentioned are avoided and the closure piece is mounted without play regardless of the size and shape of the manhole cover.
- This object is achieved by the method according to the invention in that a rapidly hardening and cold-setting liquid plastic is used as an intermediate layer, the liquid plastic is applied in a doughy state to the bearing surface of the closure piece and / or frame and then the closure piece is brought into the closed position.
- the advantages achieved with the invention consist in particular in that, by using liquid plastic, it can be applied or sprayed onto the bearing surface in a simple manner in the form of a strand.
- the liquid plastic is distributed evenly over the radial and axial bearing surface. This creates a radial and axial backlash-free form fit between the closure piece and the frame, regardless of both the size and shape of the manhole cover and the gap size between the closure piece and the frame.
- unevenness between the two storage areas is automatically compensated. Every movement of the manhole cover, e.g. when driving over a motor vehicle, excluded, whereby any wear due to friction from casting to casting is avoided or at least minimized and any noise pollution is also avoided.
- the strand to be laid can not only be adapted to any shape of the cover, but can also be interrupted for the cutouts required to operate the dirt trap. It is also advantageous that a rapidly curing liquid plastic is used. As a result, longer curing phases are left after the manhole cover is finished, because it can be used and driven on again after a short time. Since the liquid plastic used is finally cold-setting, neither equipment nor labor is required to heat the insulating material beforehand.
- Fig. 1 is a sectional view of the manhole cover
- Fig. 4 is a plan view of a double bag for liquid plastic ⁇
- Fig. 6 shows a cross section through the locking clip acc. Line VI - VI in Fig. 5;
- Fig. 9 shows a partial section of the manhole cover.
- Manhole covers are used to close any manhole openings. They have a manhole cover as a closure piece, which is inserted into a frame. The invention is explained using the example of its use on a manhole cover as it is used for covering a manhole on streets, squares or paths.
- a vertical shaft 1 At the top of a vertical shaft 1 is gem.
- Fig. 1 A frame 2 is inserted at ground level, into which a closure piece 3 is inserted. To prevent noise and wear caused by friction on the bearing surfaces when driving over the closure piece 3 by vehicles is Zwi ⁇ see the frame 2 and the closure piece 3 a cushioning intermediate layer 4 placed.
- this intermediate layer 4 consists of plastic, which has been applied or sprayed on in dough form before the closure piece 3 is inserted.
- the basic material for this consists of bitumen or a liquid plastic made of one- or multi-component material, for example from a two-component material. All-round sealed containers are used for the separate storage and transport of this material, the contents of which are mixed shortly before processing. 4, these containers are arranged in a bag 5 made of flexible, preferably transparent film.
- the bag 5 is formed, for example, as a tube welded tightly at both ends by weld seams 17 and 18. In the longitudinal region, the bag 5 is divided into two partial bags 5 1 and 5 1 1 by a releasable locking clip 6.
- the partial quantity 7 of a component A consisting of the mass of the plastic, eg polyurethane, can be accommodated, while in the other partial bag 5 1 ' the component B, like the partial quantity 8 consisting of hardener or accelerator, is stored.
- the locking clip 6 can acc. Fig. 5 can be designed as scissors, the arms of which are held in the closed position by a closure 9 in the closed position. In this, a web 10 of one scissor arm 6 'also engages in one
- Section line 12 cut open and from the opening formed in this way, the liquid plastic in the doughy, i.e. non-running state, as a 7 mm thick strand 13, for example, applied to the bearing surface 14 of the frame 2, expediently in the corner between the partial surfaces 14 ′ and 14 ′′ lying at right angles to one another or sprayed on (Fig. 2).
- the closure piece 3 is put on while the strand 13 is still soft, the liquid plastic being distributed in the gap formed between the frame 2 and the closure piece 3, as shown in FIG. 3.
- the curing takes place briefly, so that the manhole cover, for example a manhole cover to be driven by vehicles, can be released and driven on after only a few minutes.
- the time required to tidy up and load the tool is usually sufficient.
- a granulate 15 can be mixed in as a safeguard for this in the liquid plastic, for example in the subset 7 of component A.
- These granules 15 consist of spheres with a diameter of about 1 mm and a hard grain, such as PCV granules or quartz sand.
- the balls of the granulate 15 form a separation gap between the bearing surfaces of the frame 2 and the closure piece 3, which prevents direct contact. Since the spaces between the balls are filled with liquid plastic, a closed intermediate layer 4 made of plastic is created, which holds the closure piece 3 in a form-fitting manner and without play in the frame 2.
- the granulate 15 can be added during the production of the partial quantities 7 and / or 8 or can also be added subsequently during assembly.
- the liquid plastic is expediently packed in portions in the bag 5 in such a way that the content of a bag 5 is sufficient for laying a manhole cover. Furthermore, the amount can be coordinated such that the gap between frame 2 and closure piece 3 is completely filled, as can be seen in FIG. 3. This prevents dirt and dust from entering this gap and their harmful influence on the castings.
- a release agent can be applied to its bearing surface.
- the release agent is carried in a separate container, bag or the like. Conveniently, the release agent is contained, however, in a further part bag 5 '1 1, which is connected to the bag 5, as shown in FIGS. 7 and 8 show. This means that the entire equipment for inserting a shaft cover is always available.
- Section line 19 is cut open and the squeezed-out release agent is evenly distributed with a rag onto the bearing surfaces as a separation layer 20 (FIG. 9).
- the period for the subsequent application of the strand 13 to the frame 2 serves as the exposure time, after which the closure piece 3 can be inserted into the frame 2.
- An additional weld seam 21 serves as a separation from the adjacent partial bag 5 'or 5 1 '.
- the inventive method and the resulting manhole cover not only achieve a simple and safe operation, but also a damped, ie noise-free and safe manhole cover, which can also be produced in a short time. A non-resilient and radially backlash-free mounting of the closure piece is thus achieved without long curing times.
- the intermediate layer 4 made of paste-like liquid plastic is independent of the size and shape of the cover in its production.
- the intermediate layer 4 can be interrupted as desired at the radial recesses in the frame 2 necessary for hanging a dirt trap bucket. Similar interruptions can also be provided in other places.
- other containers can also be provided which are suitable for processing-appropriate preparation, such as mixing, and for strand-like dispensing onto the storage surfaces.
