Definitions

  • the invention relates to a dewatering device with a frame, at least one in a closed position resting on the frame lid and bearing means for supporting the lid in its closed position on the frame. Furthermore, the invention relates to a method for producing such a dewatering device.
  • Such a dewatering device is eg from the GB 24 386 78 A known and used in a variety of versions, in particular as a street drain, manhole cover or drainage channel.
  • damping means are used. Such rattling could occur, for example, when a vehicle is traveling over an undamped cover. The rattle is usually caused by an inaccurate or overdetermined storage of the lid in its closed position on the frame in conjunction with undesirable tolerances in the bearing means.
  • a damping means on the support surface on the frame and / or attached to the underside of the lid is used as a damping means to due to their Compressibility to compensate for the tolerances occurring in the closed position.
  • a dewatering device with a frame, at least one in a closed position resting on the frame cover and bearing means for supporting the lid in its closed position on the frame, characterized in that the bearing means at least one on the lid arranged projection and a recess formed on the frame and / or at least one arranged on the frame projection and a recess formed on the lid, wherein the recess in the closed position of the lid receives at least a portion of a projection and introduced in flowable or viscous state in the recess and contains there solidified casting material in befindlichem in the closed position lid, the one, preferably is substantially true to form, at least impression of the portion of the projection forms.
  • the aforementioned object is achieved according to a second aspect of the invention with a method for producing a dewatering device with a frame, at least one lid resting in a closed position on the frame and bearing means for supporting the lid in its closed position on the frame, wherein the bearing means at least one projection arranged on the lid and a recess formed on the frame and / or a recess formed on the frame and the recess and the projection are arranged relative to each other, that in the closed position of the lid, the recess at least a portion receives a projection, characterized in that casting material is introduced into the recess in flowable or viscous state and then solidifies there when located in the closed position cover to a, preferably substantially faithful, impression at least form of the portion of the projection.
  • a damping insert in encapsulated form can be realized, which effects an at least largely play-free mounting of the cover in its closed position on the frame, so that the cover also extends in the direction of the plane spanned by the frame or cover and thus in the horizontal direction essentially can not move.
  • This casting material is in a flowable or viscous state for the processing and is filled or introduced in this state into a depression which is provided on the frame or on the lid.
  • a projection is formed, and the recess and the associated projection are arranged and aligned with each other so that is received in the closed position of the lid on the frame of the projection of the recess and thus the projection and the associated Deep together with the damping insert made of the casting material together form a storage of the lid in its closed position on the frame.
  • the cover While the casting material is poured or introduced into the recess in a flowable or viscous state for producing a molded damping insert, during this process the cover is in its closed position on the frame and the projection projects, preferably substantially completely without contact, into the associated part Deepening.
  • corresponding spacers can be used, which support the lid on the frame at the desired height. This has the consequence that the casting material during filling in the recess, so to speak, flows around the projection around and therefore only fills the space between the projection and an inner wall bounding the recess.
  • an impression of the projection is formed in the casting material introduced into the recess, specifically from that portion of the projection which is enclosed in the recess by the casting material and thus immersed in the casting material. After hardening or solidification of the casting material, this impression retains its shape, which is then a substantially exact negative form of the projection or its corresponding section.
  • appropriate appropriate measures such as selection of suitable materials for the casting material and / or the projection and / or treatment of the projection must be made with a release agent.
  • a molded damping insert is produced, which enters through the casting and curing process described a firm connection with the inner wall delimiting the recess and thereby securely fixed to the recess having the frame or lid.
  • a recess which the Shape of the projection substantially exactly complementary maps and accommodates the corresponding projection substantially form-fitting when moving the lid in its closed position.
  • This positive connection then causes a cover seat substantially without play, so that a movement of the lid in the direction of the plane spanned by the frame or cover plane and thus in the horizontal direction is substantially excluded. Accordingly, the solution according to the invention leads to an essentially play-free cover seat and to a substantially rattle-free connection between cover and frame.
  • the casting material may preferably contain zinc, copper and / or tin or consist of zinc, copper and / or tin.
  • the casting material contains casting resin or consists of casting resin. In principle, however, other suitable materials for the casting material are conceivable.
  • the surface of at least the portion of the projection is provided with a release agent, so that after completion of the solidification process, the projection does not threaten to stick to the imprint formed by the solidified casting material in the associated depression.
  • the recess forms a pocket which is arranged on the frame, preferably on the inside thereof, or on the lid, preferably on its underside facing the frame, and preferably a support surface for support the lid may have in its closed position on the frame.
  • the recess is also conceivable to form the recess as a blind hole in the frame or lid.
  • a further preferred embodiment is characterized in that the recess tapers substantially towards its opening, so that the cross-section of the recess to its opening is reduced to a minimum value and the distance between at least two opposite sections of the recess bounding side walls of Depression reduced.
  • the recess With a lateral filling opening for filling the casting material in a flowable or viscous state and preferably to arrange a channel leading to the filling opening or a pipe leading to the filling opening, said channel or pipe preferably after solidification of the filled casting material is removable.
  • This embodiment is particularly advantageous for the case that in the closed position of the lid, the projection fills the recess so that only a relatively narrow gap remains between the projection and the inner wall of the recess, which would complicate the introduction or filling of the casting material.
  • the projection For the casting process, it is expedient to provide the projection with a tapered to its free end shape, preferably a conical or trapezoidal shape.
  • the cover should be conveniently hinged to the frame via a hinge device.
  • FIGS. 1 and 2 is shown in perspective a rectangular manhole cover according to a preferred embodiment of the invention.
  • the manhole cover has in the illustrated embodiment, a frame 2 with four adjacent lids 4, which are hinged via hinges 6 on the frame 2.
  • the Manhole cover is in Fig. 1 with closed lids 4 and thus in the closed state, in which the cover 4 rest in its closed position on the frame 2, and in Fig. 2 with opened lids 4 and thus shown in an open state, in which the lid 4 is pivoted about the hinges 6 from the frame 2 upwards and thus is in its open position.
  • Bags 8 are formed on the inside of the frame. Specifically, in the illustrated embodiment, the pockets 8 are arranged on the inner wall of the two opposite long side sections 2 a and 2 b of the rectangular frame 2. The pockets 8 are open towards the top or to the covers 4 and closed down or at its bottom. In the illustrated embodiment, the arranged at the ends of the long side portions 2 a and 2 b of the frame 2 pockets are each only about half as long as the remaining pockets 8 FIGS. 3 to 5 can be seen, in the frame 2 in the area of each pocket 8, an opening 12 is formed, which communicates with a recess 10 formed in the pocket 8 and leads to the one outside of the frame 2 mounted and projecting from the frame 2 groove 14.
  • Fig. 2 can be seen, are on those side portions 4a, 4b of the cover 4, which are parallel to the long side portions 2a, 2b of the frame 2 and adjacent to these in the closed position of the cover 4, protruding from the bottom de cover 4 protrusions 16 are arranged.
  • the projections 16 are positioned according to the pockets 8, so that in the illustrated embodiment in the closed position of the lid 4 each have a lid-side projection 16 or two lid-side projections 16 protrude into a frame-side pocket 8, like the FIGS. 3 and 4 reveal.
  • the projections 16 have a rectangular or square cross-section and a tapered end portion 16a, which has a trapezoidal shape in longitudinal section.
  • FIGS. 3 and 4 further, let in, dives in the closed position of the lid 4 of the projection 16 substantially only with its end portion 16a in the associated pocket 8, wherein in the illustrated embodiment, the recess 10 of the pockets 8 is dimensioned so that a direct contact between the projection 16 and the pocket 8 does not take place ,
  • a molded damping insert which is formed from a casting material 18, in particular Fig. 4 lets recognize.
  • This casting compound 18 is made of cast material that is in a flowable or viscous state for processing and cures after processing.
  • the casting compound 18 can be rendered into the flowable or viscous state by heating and solidifies or hardens on cooling.
  • the casting compound 18 can also be made of cast material which hardens with the aid of chemical processes.
  • zinc, copper and / or tin and / or casting resin are suitable for this purpose; but it is also conceivable in principle the use of other casting materials, provided that they can be brought into a flowable or pourable state and then harden or solidify.
  • the cover 4 is first in its closed position according to Fig. 1 brought so that the projection 16 is received with its tapered end portion 16 a contactless of the still empty recess 10 of the corresponding pocket 8, as in Fig. 3 is shown.
  • the casting material is then poured in the flowable or viscous state through the channel 14 and the opening 12 into the pocket and thus into the recess 10 until the in Fig. 4 level shown is reached.
  • an impression is formed by the projection 16 in the casting compound 18 introduced into the recess 10, in the illustrated embodiment of the end portion 16 a, which is enclosed in the recess 10 of the casting material 18 and thus immersed in this.
  • this impression retains its shape, which is then a substantially exact negative shape of the end portion 16a of the projection 16, as in FIG Fig. 5 recognizable by the reference numeral "20".
  • appropriate appropriate measures such as selection of suitable materials for the casting compound 18 and / or the projection 16 and / or treatment of the projection 16 with a not are shown separating agent.
  • the gutters 14 can now be removed;
  • the grooves 14 should preferably be fastened or formed on the frame 2 via a type of predetermined breaking point, which is not recognizable in the figures.
  • the result of this manufacturing process is a molded cushioning insert, as in Fig. 5 designated by the reference numeral "22".
  • the damping insert 22 produced in this way forms a firm connection with the inner wall 8a of the pocket 8 delimiting the depression 10 by the described casting and curing process and is thereby securely fixed to the frame 2 via the pocket 8. Due to the formation of the impression 20 of the projection 16, a recess is formed in the molded damping insert 22, which images the shape of the projection 16 or its end portion 16a substantially exactly complementary and when moving the lid 4 in its closed position receives the associated projection 16 with its end portion 16 a substantially positive fit, as a comparison of Fig. 4 With Fig. 5 lets recognize.
  • This form-fit then causes a cover seat substantially without play, so that a movement of the lid 4 in the direction of a plane defined by the frame 2 or cover 4 plane and thus in the horizontal direction is substantially excluded.
  • FIG. 2 in the illustrated embodiment in the wider pockets 8 each two adjacent prints 20 are formed.
  • a bag 8 with two adjacent prints 20 is also exemplary in FIG FIG. 6 represented, the one opposite FIG. 5 90 ° rotated cross-sectional view shows.
  • the side walls of the pocket 8 and thus the inner wall 8a are inclined inwards, so that the recess of the pocket 8 tapers to the opening at the upper end and thus the cross section of the pocket 8 to the Opening down to a minimum value.
  • This arrangement causes in a structurally particularly simple, but effective way a secure fixation of the casting compound 18 formed by curing damping insert 22 in the manner of a 'wedging', whereby falling out of the damping insert 22 is prevented from the pocket 8.
  • the inner walls 8a can also be aligned correspondingly inclined.
  • FIGS. 4, 5 and 6 While in the previous description of the manufacturing process for forming the molded damping insert 22 in the recess 10 on the FIGS. 3 to 5 was used to illustrate the manufacturing process, the representations of the FIGS. 4, 5 and 6 also on a manhole cover with ready-made molded cushioning insert 22 too. Because Fig. 4 shows the state in the closed position of the lid 4 and can see the mentioned positive connection between the end portion 16a of the projection 16 and the then solidified molding compound 18, which then yes the damping insert 22 according to the Figures 5 and 6 forms. The Figures 5 and 6 In contrast, each show the state with the lid open 4, in which the projection 16 is removed with the cover 4 accordingly.
  • FIG. 2 recognize that on the inner wall of the long side portion 2a of the frame 2 between the pockets 8 still blocks 24 are arranged. These blocks 24 each have an upwardly or to the cover 4 open threaded bore 26, which engage in these threaded holes 26 with closed lids 4 corresponding to the underside of the cover 4 formed threaded bolt 28 and lock the lid 4 to the blocks 24. As Fig. 2 can be seen, 28 spacer pins 30 are formed on both sides of the threaded bolt on the underside of the lid 4, which rest on the blocks 24 with closed lids next to the threaded holes 26.
  • a molded damping insert 22 in an associated recess 10 not only on a rectangular manhole cover, as in FIGS. 1 and 2 is exemplified, but also for example on a circular or circular manhole cover, on a street drain or on a drainage channel can be realized.
  • pockets 8 with the depressions 10 on the underside of the lid 4 and at the corresponding points projections 16 on the frame 2.
  • depressions may also be formed, for example, as a blind hole in the frame 2 or optionally also in the cover 4.
