Definitions
- the invention relates to a finished molded part made of molding compound of the type mentioned in the preamble of claim 1.
- Pre-formed parts of this type are known (DE-PS 31 10 185), in which the at least one support that can be entered with the foot is formed on the inside from a crampon, which with the aid of a special installation device as part of the molding device during the production and shaping of the finished part during this Process is molded with.
- the finished molded part is e.g. from a shaft element. e.g. Manhole ring, made of concrete, is how 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.
- the invention has for its object to provide a finished molded part 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 finished molded part 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 the molding compound is shaped with its shape, separate crampons as independent elements to be molded in during the molding process are completely unnecessary. 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 finished molded part is made of concrete, for example, there is a relatively rough concrete surface in the area of the supports, which increases the 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. It is also advantageous that finished molded parts 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 production process.
- the respective support is formed in the area of a wall thickening, namely an inside or outside wall thickening, or on or in an inside intermediate wall of the shaft element, any cross-sectional monitoring of the finished molded part in the area of the incorporated supports is avoided, so that the finished molded part at least the has the same strength as previously known finished molded parts, and this in the case of molded-in supports which are designed in particular as recesses.
- these supports in the area of an inside wall thickening, e.g. B. incorporated a longitudinal web, this wall thickening can also be used for other purposes, for. B. od to form a handrail.
- the coating according to claim 28 makes it easier to identify the supports and, depending on the color, also provides protection against corrosion. It is particularly advantageous if the finished molded part consists of a concrete that has a water / cement factor of 0.4 or less.
- the shaping of the finished molded parts is advantageously carried out by compression, in particular vibration compression, for. B. according to the known vibratory pressing process.
- compression in particular vibration compression, for. B. according to the known vibratory pressing process.
- the concrete is compacted by shaking and then released from the mold without delay, i.e. H. removed from the mold
- the formwork is removed before the binder in the molding compound has set.

- FIGS. 1 to 33 are each a finished molded part 10 made of molding compound, in particular made of concrete, including fiber concrete, sulfur concrete or the like, or Made of ceramic mass or plastic or the like.
- the finished molded part 10 consists of a shaft element 11.
- the latter can be a shaft ring, shaft neck, pipe or the like, which is generally arranged upright during installation, the central axis 12 of which is therefore essentially runs vertically.
- the latter is not mandatory. Even if an at least substantially tubular, for example cylindrical, shaft element 11 can be seen from the drawings is, this is also 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 designed, for example, 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. In the first exemplary embodiment in FIGS.
- 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.
- the inside wall thickening 22 is essentially a longitudinal, e.g. web 23 running along an inner surface line of the shaft element 11 and having 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 nm 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, for example rectangular or instead square. 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 adjacent to the inner surface of the web 23, which preferably has an essentially flat plane The top is provided with a smile, so that there is a good surface for stepping on with the respective foot.
- the respective recess 24 to 27 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. by the hocnstenenden footbridges 28th
- the one-piece design of the supports 18 to 21 increases the sense of security of someone entering a shaft designed in this way due to the massive design of the supports 18 to 21 to be favorably influenced. 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. Also, the elements of the molding device can now be designed with smaller fits and thus closer, which has the advantage that during the molding process of concrete parts any leakage currents of liquid concrete, e.g. Concrete sludge to be reduced inside the mold.
- the second exemplary embodiment differs from the first in that the foot webs 128 to 131 run along a secant and thereby approximately parallel to a vertical diametral plane 132 of the shaft element 111.
- the depressions 124 to 127 are designed as elongated and upright rectangles, so that there is a lot of space above the footbridges 128 to 131.
- the web 123 is designed as a bar which is approximately rectangular in cross section, the inner surface of which is oriented approximately parallel to the vertical diametral plane 132.
- 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.
- each recess 124 to 127 or bottom 134 is provided with at least one downwardly opening passage 133, which here consists of a bore which, for example, runs approximately parallel to the central axis 112.
- each recesses 125 to 127 there is a corresponding passage on the bottom, which corresponds to the passage 133.
- This passage has the advantage that any liquid accumulations in the bottom area of each depression 124 to 127 are eliminated 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 supports 218 to 221 likewise protrude inward beyond the inner surface 214 of the shaft element 211, the supports here also being formed by depressions 224 to 227 contained in a web 223.
- 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 bright, but are designed with a smaller radial depth.
- Width leads to correspondingly wide footbridges 228 to 231. This has the advantage that when entering the ladder designed in this way, the respective upper footbridges can be used as handles for grasping when climbing.
- the fourth exemplary embodiment shown in FIGS. 9 to 11 is similar to the second exemplary embodiment in FIGS. 4 to 6.
- the supports 313 to 321, in particular the depressions 324 and 327 are a single-row sequence anoronet. If the web 323 is of the same size, this results in much wider foot webs 323 to 331, and these too can be handled by hand when climbing and used as holding elements.
- the cross-sectional thickness of the wall 13 or 113 or 213 or 313 is also in this area, as can be seen from the inwardly projecting web 23 or 123 or 223 or respectively. 323, the same size as on the rest of the circumference.
- the respective web 23 or 123 or 223 or 323 with its foot bridges 28 to 31 or 128 to 131 or 228 to 231 or 328 to 331 thus forms a kind of ladder, the rungs of which are mentioned by the foot bridges and their spars on both sides are formed by the longitudinal walls of the web 23 or 123 or 223 or 323.
- a ladder designed in this way increases this
- the outer surfaces of the outer wall parts of the web 23 or 123 or 223 or 323 can also be used for touching and as a hait when climbing. This is particularly advantageous for the second embodiment, in which the depressions 124 to 127, insofar 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 can easily grasp the outer walls 133, 139 and also the intermediate wall 140 of the web 123 running between them.
- the webs 23 and 123 or 223 and 323 defining walls, z. B.
- the supports 418 to 421 are arranged analogously to, for example, the first exemplary embodiment in FIGS. 1 to 3, in particular the depressions 424 to 427 with foot webs 428 to 431, in a two-row sequence with a respective offset from one another.
- the fifth embodiment differs from the previous one in that in this the at least one support 418 to 421 is incorporated in the wall 413 of the shaft element 411, that is, it does not protrude inward beyond the inner surface 414.
- each support 418 to 421 extends inside the wall 413 from its inner surface 414 to its outer surface 415.
- the arrangement of each recess 424 to 427 daoei is selected such that its vertical plane of symmetry is identical to a raoiale vein, as in the first embodiment.
- the shaft element 411 is due to the inner workings incorporated in the Wanoung 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. As shown above all in FIG.
- the outer surface of the wall thickening 441 deviates from the round course of the outer surface 415. It is flat.
- the cross-section of the wall 413 increases continuously in the transition area from this round outer surface 415 to the flat outer surface of the wall thickening 441. This thickening of the wall 441 compensates for the loss of cross section which is caused by the supports 418 to 421 incorporated into the wall 413.
- FIGS. 12 to 14 Another special feature of the fifth exemplary embodiment in FIGS. 12 to 14 is that the foot webs 428 to 431 do not run in a straight line, but here in an arcuate manner, this curvature adjoining that of the inner surface 414. .
- a further peculiarity of the fifth exemplary embodiment lies in the fact that the individual depressions 424 to 427, viewed in the vertical cross section according to FIG. 13, run approximately arcuately, all of them as shown for the depression 424, with an approximately horizontal and flat surface Complete floor 434.
- the depressions, viewed in the vertical cross section are each approximately quadrangular, for example rectangular or square
- the arcuate curvature of the depressions 424 to 427 gives a different impression. This shape facilitates the shaping. 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.
- the sixth exemplary embodiment shown in FIGS. 15 to 17 is similar in terms of the arrangement of the supports 518 to 521 to the fourth exemplary embodiment in FIGS. 9 to 11, since in the sixth exemplary embodiment the supports 518 to 521 are also arranged in a single sequence with one another. Analogously to the fifth exemplary embodiment, in the sixth exemplary embodiment these supports 518 to 521 are incorporated into the wall 513 of the shaft element 511, where the resulting loss of cross-section of the wall 513 is compensated for by a wall thickening 541.
- the cross section of the shaft element 511 corresponds to that of the shaft element 411 of the fifth exemplary embodiment.
- the depressions 524 to 527 with footbridge 528 to 531 also correspond in horizontal and vertical section to the design according to FIGS.
- the description of the fifth exemplary embodiment applies accordingly to the sixth exemplary embodiment.
- the depressions 524 to 527 in the sixth exemplary embodiment in FIGS. 15 to 17, viewed in horizontal cross section are of wider dimensions. Accordingly, there are webs 523 to 531 which extend over a larger circumferential angle of the curvature of the inner surface 514, that is to say are wider. This bigger one
- Width may make it possible to use the towering footbridges 528 to 531 as handles when climbing a shaft designed in this way, as before for the others, corresponding execution examples is explained. Precisely because these footbridges 528 to 531 protrude above the bottom of the recess 524 to 527 and form strips, they are also well suited to be touched by hand.
- the seventh exemplary embodiment shown in FIG. 18 corresponds to the sixth exemplary embodiment according to FIGS. 15 to 17 with regard to the design of the shaft element 611.
- the only visible one here is a support 618, which is made from a support incorporated into the wall 613 of the shaft element 611 Indentation 624 is formed, which, like the sixth exemplary embodiment, does not have an arcuate curve, as seen in the horizontal cross-section, rising above the floor, approximately horizontal foot bridge 628, but here the foot bridge 628 runs approximately along a secant or approximately parallel to a vertical diametral plane 632 of the Shaft element 611, and thus, for example like each footbridge 328 to 331 in the fourth embodiment.
- each support 718 to 721 is likewise designed as a recess 724 to 727, which is machined into the wall 713 of the shaft element 711, with a highly protruding foot bridge 728 to 731.
- the supports 718 to 721 are also arranged one below the other in a single-row sequence.
- each depression 724 to 727 has the shape of a square, in particular a rectangle, likewise in accordance with the sixth exemplary embodiment.
- each foot web 728 to 731 is curved in an arcuate manner analogous to the sixth exemplary embodiment, the curvature corresponding to that of the inner surface 714.
- the recesses 724 to 727 are approximately rhombic here.
- the recess 724 runs inside delimiting end wall 735 approximately parallel to the vertical diametral plane 732, which contains the central axis 712.
- the bottom 734 of each recess extends as seen for the recess 724, viewed in vertical cross section from the footbridge 728 outwards and downwards, the bottom 734 and the end wall 735 extending at an angle of less than 90 ° to one another.
- the upper wall delimiting the indentation 724 at the top runs approximately parallel to the floor 734.
- the supports 818 to 821 are a one-piece, material-uniform component of the shaft element 811 and made of
- these supports 818 to 821 are formed in an intermediate wall 842 of the shaft element 811.
- the intermediate wall 842 runs approximately along a secant. It extends approximately parallel to the vertical diametral plane 832 of the shaft element 811, which contains the central axis 812. Daoei runs the partition 842 at a distance from the peripheral part of the
- the intermediate wall 842 contains depressions, in particular openings 543 to 345, which are formed, for example, as rectangular windows in the horizontal and vertical section. With this design, the supports 818 to 821 are thus contained within the intermediate wall 842.
- there is also one Arrangement on the intermediate wall 842 for example projecting inwards in the same way as in the first to fourth exemplary embodiments, or projecting radially outwards, for example incorporated, analogously in the fourth to eighth exemplary embodiments. With this design, the material webs 847 to 849 of the intermediate wall 842 present between the individual openings 843 to 846 can be grasped by hand when climbing the conductor structure thus designed, so that one can hold onto it.
- the tenth exemplary embodiment shown in FIGS. 25 to 27 corresponds, for example, with regard to the design of the supports 918 to 921, which are incorporated as recesses 924 to 927 in the wall 913 of the shaft element 911 and have upstanding foot webs 928 to 931, according to the sixth exemplary embodiment 15 to 17, wherein the foot webs 928 to 931, analogously to the seventh embodiment, run approximately parallel to the vertical diametral plane 932.
- the wall thickening 941 which is intended to compensate for the loss of cross-section caused by recesses 924 to 927 in the wall 913, reduces the material loss and Weight saving in the area of the outer surface 950 has recesses 951 which are open to the outside. It is particularly advantageous if these recesses 951, as shown in FIG. 26, are each provided at a level between two inner recesses 918 and 919 or 919 and 920 or 920 and 921 which follow one another vertically.
- a corresponding amount of material, in particular the amount of concrete, of the shaft element 911 is not absolutely necessary, so that in this area material and weight can be saved by recesses 951 located on site.
- the depth of the recesses 951 is thereby determines which remaining cross-section must not be undercut for a given minimum wall thickness.
- the shape of the recesses 951 is immaterial. It can be chosen so that the greatest possible weight and material savings are achieved while maintaining the required minimum wall thickness.
- the eleventh exemplary embodiment shown in FIGS. 28 to 30 is similar to the first to fourth exemplary embodiments, because, in the eleventh exemplary embodiment as well, the supports 1018 to 1021 as worked into a longitudinal web 1023 follow over the inner surface 1014 Indentations 1024 to 1027 protruding towards the center are formed with raised footbridges 1028 to 1031, these supports being arranged in a single row, for example roughly analogous to the fourth embodiment.
- the web 1023 has two sides
- the web 1023 has on its outer side, in particular on the radially inward-facing outer side of the outer walls 1038, 1039, gripping parts 1052 and 1053 which can be grasped by hand.
- These gripping parts 1052, 1053 are designed here as longitudinally continuous handrail strips located on the outer sides of the web 1023, in particular its outer walls 1038, 1039, which are integral with the web 1023.
- a bead 1054 or 1055 provided, which over the rear surface of the gripping part 1052 or 1053 towards Inner surface 1014 protrudes and runs at least approximately parallel to the outer wall 1038 or 1039.
- the bead 1054, 1055 not only contributes to the material reinforcement, but each gripping part 1052, 1053 together with this bead 1054 or 1055 has a particularly handy handrail, which can be gripped by hand when climbing the ladder-shaped structure created by the supports 1018 to 1021 can, whereby the security when walking and entering this ladder-shaped structure is further increased.
- the effort for the additional shaping of the gripping parts 1052, 1053 with bead 1054 or 1055 is small in relation to the improvement achieved.
- the upper wall closing the recess 1024 to 1027 at the top is slightly curved, and is convexly curved upwards.
- the base 1034 which is indicated only in the recess 1024, starting from the footbridge 1028 in the radial direction and sloping downwards along an inclined surface, as is also the case with the base in the eighth embodiment the case is.
- the bottom 1034 has no connection to the wall 1013, but there is a downwardly open passage 1033 in the bottom 1034, which here is approximately slit-shaped and extends over the entire width of the footbridge 1028.
- the slope of the floor 1034 has the advantage that any liquids, impurities or the like, which could settle on the floor 1034, slide backwards due to the slope and are flushed backwards and then flow down through the passage 1033, so that the depressions 1024 to 1027 in this floor area experience an especially good self-cleaning.
- the twelfth exemplary embodiment shown in FIGS. 31 to 33 corresponds to the fourth exemplary embodiment in FIGS. 9 to 11, with the only difference that in the twelfth exemplary embodiment the web 1123 is analogous to the eleventh exemplary embodiment in FIGS. 28 to 30 on the outside the outer walls 1138, 1139 are provided with handle parts 1152, 1153 and bead 1154 and 1155 and handrails designed in this way.
