Definitions

  • the invention relates to a shaft element made of molding material of the type mentioned in the preamble of claim 1.
  • Shaft elements of the type mentioned at the outset are known (GB-A-209 931) which have a constant wall thickness all around and have material-uniform supports on the inside which are shaped as projections projecting inward in the manner of a balcony. When viewed from above, the projections have the shape of a hollow semi-basin. Such protrusions are difficult to form during manufacture. They are only lightly loadable and can break off easily.
  • shaft elements known (DE-31 10 185 A1), in which the at least one foot-accessible support is formed on the inside from a crampon which, with the help of a special installation device, is part of the molding device during the manufacture and molding of the finished molded part during this process is molded.
  • the finished molded part consists of a manhole element, e.g. manhole ring, made of concrete, the crampons are concreted in from the inside during the shaping process.
  • These crampons have to be procured as special costly elements, kept in stock and stored in a magazine and fed and placed in the molding device during the shaping process. This is complex and expensive.
  • the invention has for its object to provide a shaft element of the type mentioned in the preamble of claim 1 that makes separate crampons unnecessary while maintaining the strength and leads to a reduction in effort and costs.
  • the object is achieved in a shaft element of the type defined in the preamble of claim 1 according to the invention by the features in the characterizing part of claim 1.
  • Characterized in that the at least one support is an integral part of the shaft element and from its molding compound is shaped at the same time, separate crampons as independent, completely unnecessary in the molding process with elements to be molded.
  • the associated expenditure on procurement, storage and provision as well as introduction into the molding device is completely eliminated. This leads to a significant reduction in working hours and costs. This means that any interruptions in the automatic manufacturing process that were otherwise necessary for inserting the crampons, depending on the process, are no longer necessary.
  • the automatic manufacturing process can run uninterrupted.
  • the shaft element is made of concrete, for example, there is a relatively rough concrete surface in the area of the supports, which increases slip resistance.
  • the incorporated supports also due to the increased slip resistance, increase the overall feeling of safety of the person who has to walk on a shaft formed from such shaft elements. Any repair work in the shaft can thus also be carried out more easily and safely, whereby this is also carried out more readily.
  • shaft elements with all elements can thus be produced in one piece and in one process and therefore a higher level of tightness can be ensured in the manufacturing process. The advantages are thus a significant reduction in costs, time savings in production, a large amount of creative freedom for the design with regard to the shape and dimensions of the shaft elements, as well as greater stability and security as well as great durability and ease of repair and maintenance.
  • the shaft elements are advantageously compressed, in particular vibration-compressed. This is done by making z. B. according to the known vibratory pressing process.
  • the concrete is compacted by shaking and then immediately removed from the mold. H. removed from the mold, whereby the formwork is removed before the binder of the molding compound has set.
  • the manufacturing process for the manufacture of such shaft elements is fully automatic.
  • the shaft element is immediately removed from the mold after compaction and transported - resting on a lower base ring (lower sleeve).
  • all twelve exemplary embodiments according to FIGS. 1 to 33 are each a finished molded part 10 made of molding compound, in particular of concrete, which also includes fiber concrete, sulfur concrete or the like, or of ceramic compound or plastic or the like.
  • the finished molded part 10 consists of a manhole element 11.
  • the latter can be a manhole ring, manhole neck, pipe or the like, which is usually arranged upright during installation, with its central axis 12 thus running essentially vertically.
  • the latter is not mandatory.
  • the shaft element 11 can also be conical or polygonal, for example square, oval, elliptical or in some other way. All different forms are within the scope of the invention.
  • the shaft element 11 shown in the drawings has a wall 13 which is delimited by a curved inner surface 14 and a curved outer surface 15.
  • the cross-section of the wall 13 is at least substantially uniform, with the exception of the exceptions that are particularly emphasized in the following description.
  • each shaft element 11 is provided with folds 16 and 17 shaped in a conventional manner, which allow a plurality of stacked shaft elements 11 to fit into one another with a seal therebetween.
  • the shaft element 11 is e.g. designed according to DE-PS 31 10 185, to which reference is made and the content of which is made here for disclosure.
  • the shaft element 11 has at least one support 18 that can be entered with the foot.
  • a total of four supports 18, 19 and 20, 21 are visible, with which the shaft element 11 is equipped.
  • these supports are formed by crampons which are concreted in from the inside into the finished molded part 10 to be shaped, in particular the shaft element 11, during the shaping process.
  • These are prefabricated crampons made of cast iron, stainless steel, stainless steel tube with plastic coating, aluminum, aluminum tube, aluminum tube with plastic coating or other material.
  • These crampons are expensive. The manufacture of crampons is already expensive. It requires corresponding raw materials and energy expenditure for the production. Furthermore, such crampons are exposed to corrosion, which is why shaft elements 11 equipped with them also require control and maintenance.
  • the supports 18 to 21 are a one-piece, material-uniform component of the shaft element 11, which can also be molded from the molding compound during its shaping and have been molded in the finished product shown. Even if several supports, namely four supports 18 to 21, are provided in the first exemplary embodiment according to FIGS. 1 to 3, it goes without saying that at least one support in the shaft element 11 can also be sufficient. In the first exemplary embodiment in FIGS. 1 to 3, the respective support 18 to 21 projects inward beyond the inner surface 14 of the shaft element 11.
  • the supports 18 to 21 are formed on an inside wall thickening 22 of the shaft element 11.
  • the inside wall thickening 22 is essentially designed as a longitudinal web 23, for example running along an inner surface line of the shaft element 11, which has a substantial width.
  • this web 23, viewed in the horizontal section according to FIG. 1, has an at least weak V-shape.
  • the supports 18 to 21 are formed from respective depressions 24 to 27 which are contained in the interior of the web 23.
  • the web 23 has approximately the shape of a longitudinal bar, which is a longitudinal bar with an approximately rectangular cross section, which corresponds to the Inner surface 14 is attached and follows the curve of the inner surface 14 and further inside has slightly inclined outer surfaces, this longitudinal bar of course being integral with the wall 13.
  • the supports 18 to 21, in particular depressions 24 to 27, in the web 23 are arranged in a two-row sequence with a respective offset from one another.
  • the supports 18 to 21 can have a width of approximately 125 to 150 mm and in the case of a single-track arrangement a width of approximately 300 to 400 mm.
  • the depressions 24 to 27 are each approximately square, e.g. rectangular or square instead. As can be seen above all from FIGS. 1 and 3, the depressions 24 to 27 have a substantial width, so that they are well suited as supports that can be entered. It is of particular importance, among other things, that the supports 18 to 21, in particular depressions 24 to 27, each have an upstanding and approximately horizontal footbridge 28 to 31 which adjoins the inner surface of the web 23 and which preferably has an essentially flat upper surface is provided, so that there is a good area to occur when entering with the respective foot.
  • the respective recess 24 to 27, viewed in cross section, is approximately box-shaped in the first exemplary embodiment according to FIGS. 1 to 3.
  • this depression has a bottom 34, an end wall 35 delimiting the depression on the inside and two side walls 36 and 37 which run approximately parallel to one another and which enter the depression 24 when the footbridge 28 is entered gripping part of the foot ensure good and safe lateral guidance.
  • the footbridge 28 clearly protrudes upward above the floor 34.
  • the other recesses 25 to 27 are designed in the same way as explained above for recess 24.
  • the bottom 34 of the respective recess 24 to 27 runs approximately horizontally here.
  • the inner end wall 35 which limits the depth of the recess 24, runs in an arc shape according to FIG. 1, which roughly follows the curvature of the inner surface 14.
  • the one-piece design of the supports 18 to 21 results in greater leeway for such finished molded parts 10, in particular shaft elements 11.
  • Appropriate design can thus have a positive influence on climbing safety, climbing ergonomics and the like parameters. Safety against slipping is also considerably increased. This is z. B. achieved by the highest footbridges 28 to 31, which can also be grasped by hand, and also by the bilateral limitation by means of the side walls 36 and 37, which prevent slipping to the side. It is also advantageous that due to the massive design of the supports 18 to 21 to be stepped on, the security perception of someone entering a shaft designed in this way is favorably influenced by the one-piece design of the supports 18 to 21. It is also advantageous that the molding devices required for the production of the finished molded parts 10, in particular shaft elements 11, no longer have to be adapted to the ever different shapes and dimensions of crampons.
  • the elements of the molding device can now be designed with fewer fits and thus denser, which has the advantage that any leakage flows of liquid concrete, for example concrete sludge, into the interior of the molding device are reduced during the molding process of concrete parts. It is also advantageous that the otherwise required insertion devices, by means of which the separate crampons were inserted, are unnecessary, which leads to a further reduction in costs. The steps of equipping an insertion device with crampons and inserting the insertion device into the molding device are also eliminated, which leads to a further reduction in the outlay. Since crampons no longer have to be stored, transported and handled at all, the additional times and interruptions in the automatic manufacturing process that result from this are eliminated. The invention enables uninterrupted, fully automated production.
  • the finished molded part 10, in particular shaft element 11, is of homogeneous quality and a constant seal also in the area of the supports 19 to 21. Overall, there is an enormous reduction in costs, greater stability, tightness, safety, durability, ease of maintenance, time saving during production and larger creative freedom for the design of the finished molded part 10.

  • the two side walls 136 and 137 of the depression 124 which run parallel to one another, are oriented essentially at right angles to the diametral plane 132 and are therefore along a secant and not radially, as in the first exemplary embodiment.
  • the side walls of the other depressions 125 to 127 are of course also formed in the same way.
  • the base 134 is provided with at least one downwardly opening passage 133 for each recess 124 to 127, which here consists of a bore which, for example, runs approximately parallel to the central axis 112.
  • This passage has the advantage that any liquid accumulations in the bottom area of each depression 124 to 127 are switched off because liquids can flow down through these passages 133.
  • the foot webs 128 to 131 are in alignment with one another and approximately parallel to the vertical diametral plane 132, which leads through the central axis 112, simplifying the manufacture of this shaft element 111.

  • the web 223 has a larger width here.
  • its outer surface extends essentially parallel to a diametral plane 232 which passes through the central axis 212.
  • the supports 218 to 221, in particular the depressions 224 to 227 are arranged in a single-row sequence, in deviation from the first and second exemplary embodiments.
  • the recesses 224 to 227 viewed in the horizontal cross section, are also very wide, but are designed with a smaller radial depth.
  • the large width leads to correspondingly wide footbridges 228 to 231.
  • This has the advantage that when stepping onto the ladder designed in this way, the respective upper footbridges can be used as handles for grasping when climbing.
  • this is of course also possible in the previous exemplary embodiments.
  • the design according to this third exemplary embodiment is predestined for this.
  • the fourth exemplary embodiment shown in FIGS. 9 to 11 is similar to the second exemplary embodiment in FIGS. 4 to 6.
  • the supports 318 to 321, in particular the depressions 324 to 327 are a single-row sequence arranged. If the web 323 is of the same size, this results in much wider foot webs 328 to 331, and these too if necessary handled by hand when climbing and can be used as holding elements.
  • the cross-sectional thickness of the wall 13 or 113 or 213 or 313 is also in this area, apart from the inwardly projecting web 23 or 123 or 223 or 323, the same size as on the rest of the circumferential course.

  • the outer surfaces of the outer wall parts of the web 23 or 123 or 223 or 323 can also be used for gripping and as a hold when climbing. This is particularly advantageous for the second embodiment, in which the depressions 124 to 127, as far as they extend above the foot bridges 128 to 131, are very large in the vertical direction and thus offer large free spaces, so that when climbing this one Conductor structure can easily grasp the outer walls 138, 139 and also the intermediate wall 140 of the web 123 running between them.

  • the shaft element 411 is through the inner worked into the wall 413 Recesses 424 to 427 weakened in cross section. For this reason, the shaft element 411 has, on the wall area on which the supports 418 to 421 incorporated into the wall 413 are located, a wall thickening 441 which, for example, is designed to be essentially continuous and, for example, is directed outwards.

  • the arcuate curvature of the depressions 424 to 427 gives a different impression. This shape makes molding easier. It leads to the fact that each recess 424 to 427, viewed in the vertical section according to FIG.
  • An end wall delimiting the recess on the inside, as in the first to fourth exemplary embodiments, which is directed approximately at right angles to the top wall of the recess, does not therefore exist in this arch shape of the recesses 424 to 427, in which the top wall and the end wall form one due to the arch boundary inner arc surface are fused, which extends in the arc from the inner surface 414 to the bottom 434 and is spaced above the foot bridge 428 to 431.
