Definitions
- the present invention relates to a structural element for connecting a shaft structure to a traffic area surrounding the shaft structure, having a first and a second end face, a front and a rear side, and a lower and a upper side according to the preamble of claim 1.
- Compactable asphalt pavements are bituminous mixtures of aggregates and bitumen as a binder, which complies with the applicable rules and regulations.
- the bituminous mixture is applied to the traffic area in a hot condition and is compulsorily fed to compaction by means of compactors.
- Mastic asphalt is a mixture of fine and coarse aggregates with bituminous binders, such as road construction bitumen acc. ⁇ norm B3610 or polymer modified bitumen acc. ⁇ norm B3613, which is cast in viscous form and also forms a road surface after cooling. In contrast to the above-mentioned asphalt coverings, no compaction is required when using mastic asphalt.

- paving stones are produced in diced form. Nevertheless, in order to connect shaft structures of different sizes to traffic areas, the paving stones must be made relatively small in order to be flexible in this regard and to optimally enclose and even connect small sizes of the shaft structures.
- the smaller the paving stones the higher the laying effort and the thinner the load-bearing layer that they themselves represent. Small stone formats can not contribute to reducing the relative movement between manhole structure and traffic area, so that the damage described above is only slightly reduced.
- paving stones generally have a polishable surface which, in turn, is a risk factor especially for single-lane vehicles. Cracks within the paving stone construction also shorten their life, since the penetration and freezing of water whose weathering, for example by breaking open the paving stone construction, is accelerated. Also, modification work is difficult because the entire paving stone construction forms a relatively rigid unit, so that individual paving stones are difficult to replace this.

Description
Die vorliegende Erfindung bezieht sich auf ein Bauelement zur Anbindung eines Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche mit einer ersten und zweiten Stirnseite, einer Vorder- und einer Rückseite und einer Unter- und einer Oberseite gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a structural element for connecting a shaft structure to a traffic area surrounding the shaft structure, having a first and a second end face, a front and a rear side, and a lower and a upper side according to the preamble of
In der Praxis werden Verkehrsflächen mit einem Fahrbahnbelag versehen, um das Befahren mit Kfz und Fahrrädern zu ermöglichen, Abstellflächen für den ruhenden Verkehr zu bilden oder das Begehen durch Fußgänger zu erlauben. Aus der
Für diesen Fahrbahnbelag kommen entweder verdichtungsfähige Asphaltbeläge oder aber Gussasphalt zum Einsatz.For this road surface either compactable asphalt pavements or mastic asphalt are used.
Bei verdichtungsfähigen Asphaltbelägen handelt es sich um Asphaltmischgut aus Gesteinskörnungen und Bitumen als Bindemittel, welches den gültigen Regeln und Vorschriften entspricht. Das Asphaltmischgut wird in heißem Zustand auf die Verkehrsfläche aufgetragen und zwingend einer Verdichtung mittels Verdichtungsgeräten zugeführt.Compactable asphalt pavements are bituminous mixtures of aggregates and bitumen as a binder, which complies with the applicable rules and regulations. The bituminous mixture is applied to the traffic area in a hot condition and is compulsorily fed to compaction by means of compactors.
Bei Gussasphalt hingegen handelt es sich um ein Gemisch aus feinen und groben Gesteinskörnungen mit bituminösen Bindemitteln, wie beispielsweise Straßenbaubitumen gem. Önorm B3610 oder polymermodifziertes Bitumen gem. Önorm B3613, das in zähflüssiger Form vergossen wird und nach dem Erkalten ebenfalls einen Fahrbahnbelag bildet. Im Gegensatz zu den oben erwähnten Asphaltbelägen ist bei der Anwendung von Gussasphalt kein Verdichten erforderlich.Mastic asphalt, on the other hand, is a mixture of fine and coarse aggregates with bituminous binders, such as road construction bitumen acc. Önorm B3610 or polymer modified bitumen acc. Önorm B3613, which is cast in viscous form and also forms a road surface after cooling. In contrast to the above-mentioned asphalt coverings, no compaction is required when using mastic asphalt.
Unterhalb von mit einem Fahrbahnbelag versehenen Verkehrsflächen verlaufen in der Regel Abwasserleitungen oder andere Leitungen der Infrastruktur in Form von Rohren und Kabeln. Um Zugang zu diesen Rohren und Kabeln zu schaffen, sind die Verkehrsflächen in meist unregelmäßigen Abständen mit vertikal vom Fahrbahnbelag nach unten verlaufenden, im Wesentlichen zylindrische Form aufweisenden Schachtbauwerken versehen, welche einen Schachtaufbau aufweisen, auf den noch später näher eingegangen wird und einen befahrbaren/begehbaren Schachtdeckel aufweisen. Die Schachtdeckel sind planmäßig auf das Niveau des umgebenden Fahrbahnbelags ausgerichtet, um möglichst geringe Unebenheiten beim Überqueren der Schachtdeckel zu gewährleisten.Underneath traffic areas provided with a road surface, sewage pipes or other lines of the infrastructure generally run in the form of pipes and cables. In order to provide access to these pipes and cables, the traffic areas are provided in mostly irregular intervals with vertical from the road surface downwardly extending, substantially cylindrical shape having shaft structures, which have a shaft structure, which will be discussed in more detail later and a passable / accessible Have manhole cover. The manhole covers are planned according to the level of the surrounding road surface to ensure the least possible unevenness when crossing the manhole cover.
Als problematisch erweist sich in der Praxis stets die Anbindung der Schachtbauwerke an die umgebende Verkehrsfläche, insbesondere an den Fahrbahnbelag.In practice, the connection of the shaft structures to the surrounding traffic area, in particular to the road surface, always proves problematic.
Asphaltbeläge werden gemäß dem Stand der Technik direkt an das Schachtbauwerk herangeführt und sind in der Folge mit diesem über ein Bindemittel wie Bitumen, verbunden. Bislang ist es aus den folgenden Gründen nicht gelungen, diese Anbindung dauerhaft und flexibel zu gestalten:
- Setzung des Schachtbauwerkes aufgrund hoher, dynamischer Verkehrslasten
- Setzung des gesamten Schachtbauwerkes aufgrund schlechter Bodenverhältnisse im Bereich des Schachtfundaments
- Frosthebungen im Umgebungsbereich des Schachtes wobei das tief gegründete Schachtbauwerk der Hebung nicht folgt
- zyklisch auftretende vertikale Bewegungen zwischen der Oberfläche des Fahrbahnbelags und dem Schachtbauwerk, ausgelöst durch Frosthebung des Fahrbahnaufbaus im Winter und darauffolgender Setzung in der Tauperiode
- einmalige Setzungen des Fahrbahnaufbaus infolge mangelhafter Verdichtung
- Streusalz und im Abwasser vorhandene Chemikalien, welche unter anderem die Mörtelfugen im Schachtaufbau zerstören
- Setting the shaft structure due to high, dynamic traffic loads
- Settlement of the entire shaft structure due to poor ground conditions in the area of the shaft foundation
- Freezing in the surrounding area of the shaft, whereby the deeply established shaft structure does not follow the uplift
- Cyclic vertical movements between the surface of the road surface and the shaft structure, triggered by freezing of the roadway structure in winter and subsequent settlement in the dew period
- One-time subsidence of the roadway structure due to insufficient compaction
- Road salt and chemicals present in the wastewater, which among other things destroy the mortar joints in the shaft structure
Trotz entsprechender Dimensionierung der Schachtaufbauten führen diese Umstände dazu, dass vor allem im Nahbereich von Schächten bzw. Schachtdeckeln erhebliche Fahrbahnschäden schon nach wenigen Jahren entstehen. Dies bewirkt als direktes Ergebnis
- eine hohe Geräuschentwicklung ("klappern") der Schachtdeckel aufgrund exzentrischer Verkehrslasten oder mangelhafter Versetzarbeit
- eine Zerstörung des oberen Schachtbereiches durch Impulsbelastungen bei der Überrollung
- ein erhöhtes Unfallrisiko vor allem für einspurige Verkehrsteilnehmer beim Überfahren der aufgrund der obigen Umstände über den Fahrbahnbelag hinausragenden oder gegenüber dem Fahrbahnbelag nach unten versetzten Schachtdeckel
- eine schollen- oder netzförmige Rissbildung rund um den Schachtdeckel
- eine mangelhafte Schneeräumung durch den Winterdienst
- die fortschreitende Zerstörung des Schachtbauwerks und des Fahrbahnbelages
- a high noise ("rattling") of the manhole cover due to eccentric traffic loads or poor Versetzarbeit
- a destruction of the upper shaft area by impulse loads during the overrun
- an increased accident risk especially for single-lane road users when driving over the due to the above circumstances on the road surface protruding or compared to the road surface down offset manhole cover
- a lump or net-shaped cracking around the manhole cover
- a deficient snow removal by the winter service
- the progressive destruction of the shaft structure and the road surface
Auch beim Einsatz von Gussasphalt kommt es zu identischen Problemen, da sich dieser im Wesentlichen wie verdichtungsfähige Asphaltbeläge verhält.Even with the use of mastic asphalt, there are identical problems, as this behaves essentially like compactable asphalt pavements.
Während es eine Anzahl an gebräuchlichen Methoden zur Behebung der genannten Schäden gibt, zielt die vorliegende Erfindung darauf ab, die Auswirkungen der genannten Schadenstypen zu verhindern bzw. minimieren. Es können somit sowohl laufende Instandhaltungsmaßnahmen reduziert werden als auch die Lebensdauer von Schachtbauwerk und Verkehrsfläche erhöht werden.While there are a number of common methods of remedying the above mentioned harms, the present invention aims to prevent or minimize the effects of the mentioned types of damage. Thus, both ongoing maintenance measures can be reduced and the service life of the shaft structure and traffic area can be increased.
Eine manchmal, vorwiegend in urbanen Gegenden, zum Einsatz kommende Technik ist jene der Anbindung des Schachtbauwerks an die umgebende Verkehrsfläche mittels zusätzlicher Bauelemente in Form von Pflastersteinen. Diese sind in der Regel aus Naturstein gefertigt. Obwohl sowohl Schachtdeckel, als einer von mehreren, das Schachtbauwerk aufbauende Bestandteilen, als auch die zur Anbindung verwendeten Bauelemente genau genommen selbst Bestandteil der Verkehrsfläche sind, wird für die Zwecke der vorliegenden Anmeldung unter Verkehrsfläche jene, das Schachtbauwerk bzw. dessen Bestandteile sowie die Bauelemente umgebende Verkehrsfläche verstanden.A technique sometimes used, mainly in urban areas, is that of connecting the shaft structure to the surrounding traffic area by means of additional building elements in the form of paving stones. These are usually made of natural stone. Although both manhole cover, as one of several, the shaft structure constituent components, as well as the components used for connection are actually part of the traffic surface itself, is for the purposes of the present application under traffic area that, the shaft structure or its components and the components surrounding Traffic surface understood.
Die Pflastersteine werden dabei das Schachtbauwerk umschließend, häufig entlang eines Kreises, aneinander gereiht, und mittels eines Verbindemittels, vorzugsweise Pflasterfugenmörtel oder Bitumenvergussmasse, untereinander verbunden und an das Schachtbauwerk einerseits und der Verkehrsfläche andererseits angebunden.The paving stones are the shaft structure surrounding, often along a circle, lined up, and connected to each other by means of a connector, preferably plaster joint mortar or Bitumenvergussmasse and connected to the shaft structure on the one hand and the traffic area on the other.
Die Übergänge zur Verkehrsfläche, die in der Regel aus Straßenasphalt besteht, bzw. zum Schachtbauwerk sind dabei allerdings aus folgenden Gründen problematisch:However, the transitions to the traffic area, which as a rule consists of road asphalt, or to the shaft structure, are problematical for the following reasons:
Aus Kostengründen werden Pflastersteine in würfeliger Form hergestellt. Um dennoch Schachtbauwerke unterschiedlicher Größen an Verkehrsflächen anbinden zu können, müssen die Pflastersteine relativ klein gefertigt werden, um diesbezüglich flexibel zu sein und auch kleine Größen der Schachtaufbauten optimal umschließen und damit anbinden zu können. Je kleiner die Pflastersteine, desto höher ist jedoch der Verlegeaufwand und desto dünner ist auch die tragfähige Schicht, die sie selbst darstellen. Kleine Steinformate können auch nicht zur Verringerung der Relativbewegung zwischen Schachtbauwerk und Verkehrsfläche beitragen, so dass sich das weiter oben beschriebene Schadensbild nur unwesentlich verringert.For reasons of cost paving stones are produced in diced form. Nevertheless, in order to connect shaft structures of different sizes to traffic areas, the paving stones must be made relatively small in order to be flexible in this regard and to optimally enclose and even connect small sizes of the shaft structures. However, the smaller the paving stones, the higher the laying effort and the thinner the load-bearing layer that they themselves represent. Small stone formats can not contribute to reducing the relative movement between manhole structure and traffic area, so that the damage described above is only slightly reduced.
Hinzu kommt, dass Pflastersteine darüber hinaus im Allgemeinen über eine polierfähige Oberfläche verfügen, die wiederum speziell für einspurige Fahrzeuge einen Risikofaktor darstellt. Risse innerhalb der Pflastersteinkonstruktion verkürzen darüber hinaus deren Lebensdauer, da durch das Eindringen und Gefrieren von Wasser deren Verwitterung, beispielsweise durch Aufsprengen der Pflastersteinkonstruktion, beschleunigt wird. Auch Änderungsarbeiten gestalten sich schwierig, da die gesamte Pflastersteinkonstruktion eine relativ starre Einheit ausbildet, so dass einzelne Pflastersteine hierdurch nur schwierig austauschbar sind.In addition, paving stones generally have a polishable surface which, in turn, is a risk factor especially for single-lane vehicles. Cracks within the paving stone construction also shorten their life, since the penetration and freezing of water whose weathering, for example by breaking open the paving stone construction, is accelerated. Also, modification work is difficult because the entire paving stone construction forms a relatively rigid unit, so that individual paving stones are difficult to replace this.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Bauelement zur Anbindung Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche zu realisieren, das die genannten Nachteile vermeidet und darüberhinaus eine verbesserte Verkehrssicherheit bietet, einfach nachbearbeitet werden kann, durch seine Langlebigkeit den erforderlichen Wartungsaufwand als auch die damit verbunden Kosten minimiert, möglichst einfach zu fertigen und zu verbauen ist und bei größtmöglicher Stabilität direkt aneinander reihbar ist.It is therefore an object of the present invention to realize a structural element for connecting the shaft structure to a shaft structure surrounding the traffic area, which avoids the disadvantages mentioned and, moreover, provides improved traffic safety, simply reworked can be minimized by its longevity the required maintenance and the associated costs, as simple as possible to manufacture and build is and with the greatest possible stability directly to each other is reihbar.
Es ist ein weiteres Ziel der vorliegenden Erfindung, ein Bauelement vorzusehen, das leicht an die Form des anzubindenden Schachtbauteils angepasst werden kann.It is a further object of the present invention to provide a component which can be easily adapted to the shape of the manhole component to be connected.
Darüber hinaus hat die Erfindung die Aufgabe, eine Anordnung zur Anbindung eines Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche zur Verfügung zu stellen, die eine stabile und witterungsbeständige Anbindung gewährleistet, für unterschiedliche Schachtaufbauten einsetzbar ist und durch die Anwendung von optimierten Verfahren hergestellt werden kann.In addition, the invention has the object to provide an arrangement for connecting a shaft structure to a shaft structure surrounding traffic area available, which ensures a stable and weather-resistant connection, can be used for different manhole structures and can be produced by the application of optimized methods.
Eine weitere Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zur Anbindung eines Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche zu schaffen.A further object of the present invention is to provide a method for connecting a shaft structure to a traffic area surrounding the shaft structure.
Erfindungsgemäß wird dies bei einem Bauelement zur Anbindung eines Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche mit einer ersten und zweiten Stirnseite, einer Vorder- und einer Rückseite, und einer Unter- und einer Oberseite, dadurch erreicht, dass es sich bei dem Bauelement um ein aus Gussasphalt gefertigtes Formbauelement handelt. Unter Formbauelement wird ein Bauelement verstanden, das neben der üblichen quaderform herkömmlicher Bauelemente, wie beispielsweise den erwähnten Pflastersteinen, auch von dieser abweichende Formen aufweisen kann. Die Herstellung der erfindungsgemäßen Formbauelemente erfolgt durch Gießen in einer Gussform vorzugsweise aus Stahl. Das Gemisch ist im heißen Zustand vor dessen Aushärtung gieß- und streichbar, und bedarf zu dessen Aushärtung keiner Verdichtungsarbeit. Das so beschaffene Formbauelement ist dadurch besonders einfach zu fertigen, und kann abhängig von der Gussform in seiner Form weitgehend frei gestaltet werden.According to the invention, this is achieved in a component for connecting a shaft structure to a traffic area surrounding the shaft structure with a first and second end face, a front and a rear side, and a bottom and a top, characterized in that it is at the component of a Mastic asphalt manufactured molded component acts. The term "molded component" is understood to mean a component which, in addition to the usual cuboidal shape of conventional components, such as, for example, the paving stones mentioned, may also have different shapes from those. The production of the mold components according to the invention is carried out by casting in a mold, preferably made of steel. The mixture is pourable and spreadable when hot before curing, and requires no condensation work to cure it. The thus-obtained molded component is characterized particularly easy to manufacture, and can be made largely free depending on the mold in its shape.
So kann das Profil der zweiten Stirnseite im Wesentlichen die negative Kontur der ersten Stirnseite darstellen, wobei unter negativer Kontur der ersten Stirnseite das Profil einer Form verstanden wird, die bei Anbringen an die erste Stirnseite diese formschließend und ohne Rücklassen von Öffnungsbereichen abdeckt. Erfindungsgemäße Formbauelemente sind somit direkt und formschließend aneinander reihbar und besonders einfach zu verbauen. Der Einsatz von Formbauelementen aus Gussasphalt ist speziell dann vorteilhaft, wenn das Formbauelement im Zusammenhang mit einer Verkehrsfläche aus Asphalt (Gussasphalt oder verdichtungsfähige Asphaltmischgutsorten) zum Einsatz kommt.Thus, the profile of the second end face can essentially represent the negative contour of the first end side, wherein the negative contour of the first end face is understood to mean the profile of a shape which, when attached to the first end face, covers it in a form-fitting manner and without leaving behind opening areas. Inventive mold components are thus directly and form-fitting can be connected to each other and particularly easy to install. The use of molded components made of mastic asphalt is particularly advantageous when the mold is used in connection with a traffic area made of asphalt (mastic asphalt or compactable asphalt mixes).
Erfindungsgemäße Formbauelemente weisen in diesem Fall den weitgehend gleichen Elastizitätsmodul wie die umgebende Verkehrsfläche auf, wodurch eine Relativverschiebung zum Asphalt und die damit verbunden Rampenbildung minimiert wird. Auch die Bildung von Rissen wird weitgehend vermieden, womit geringerer Verschleiß, erhöhte Witterungsbeständigkeit, erhöhte Sicherheit als auch erhöhter Nutzungskomfort einhergehen. Die vorgeschlagenen Formbauelemente aus Gussasphalt sind einfach zu bearbeiten und können beispielsweise bei üblichen Ausbesserungsarbeiten wie herkömmlicher Asphalt gefräst werden. Darüber hinaus sind erfindungsgemäße Formbauelemente aus Gussasphalt in unterschiedlichen Größen herstellbar, wodurch sie zur Ummantelung für verschiedene Schachtbauwerke verwendbar sind.Form components according to the invention have in this case the largely same modulus of elasticity as the surrounding traffic surface, whereby a relative shift to the asphalt and the associated ramp formation is minimized. The formation of cracks is largely avoided, which is associated with lower wear, increased weather resistance, increased safety and increased ease of use. The proposed mold components made of mastic asphalt are easy to machine and can be milled, for example, in conventional repair work such as conventional asphalt. In addition, mold components according to the invention made of mastic asphalt in different sizes can be produced, whereby they can be used for sheathing for various manhole structures.
In einer bevorzugten Ausführungsvariante der Erfindung weisen die erste und die zweite Stirnseite eines erfindungsgemäßen Formbauelementes in einer Blickrichtung parallel zur jeweiligen Stirnseite jeweils ein gestuftes Profil mit jeweils mindestens einer Stufe auf, wobei die Kante der mindestens einen Stufe von der Vorder- zur Rückseite durchgängig verläuft. Bevorzugt ist die mindestens eine Stufe der ersten Stirnseite dergestalt angeordnet, dass deren Kante bei einer Draufsicht auf die Oberseite des Formbauelementes sichtbar ist, und dass die Kante der mindestens einen Stufe der zweiten Stirnseite bei einer Draufsicht auf die Unterseite des Formbauelementes sichtbar ist. Hierdurch ist im Falle einer Aneinanderreihung der Formbauelemente die Entstehung einer Verzahnung gewährleistet, die eine stabile Verbindung der Formbauelemente ermöglicht.In a preferred embodiment of the invention, the first and the second end face of a molded component according to the invention in a viewing direction parallel to respective end face in each case a stepped profile, each with at least one step, wherein the edge of the at least one step from the front to the back runs continuously. Preferably, the at least one step of the first end face is arranged such that its edge is visible in a plan view of the top of the mold component, and that the edge of the at least one step of the second end face is visible in a plan view of the underside of the mold component. In this way, in the case of a juxtaposition of the mold components, the formation of a toothing ensures that enables a stable connection of the mold components.
In einer besonders bevorzugten Ausführungsvariante weist das Profil der ersten Stirnseite genau zwei Stufen und das Profil der zweiten Stirnseite genau eine Stufe auf.In a particularly preferred embodiment, the profile of the first end face exactly two stages and the profile of the second end face exactly one step.
Dabei sind die beiden Stufen der ersten Stirnseite vorzugsweise dergestalt angeordnet, dass deren Kanten bei einer Draufsicht auf die Oberseite des Formbauelementes sichtbar sind und die eine Stufe der zweiten Stirnseite vorzugsweise dergestalt angeordnet, dass deren Kante bei einer Draufsicht auf die Unterseite des Formbauelementes sichtbar ist. Eine Draufsicht auf die Vorderseite des Formbauelements zeigt daher eine Form, die im Wesentlichen einem Parallelogramm ähnelt. Hierdurch wird das Aneinanderfügen der Formbauelemente besonders stabil und einfach realisierbar.In this case, the two stages of the first end face are preferably arranged such that their edges are visible in a plan view of the top of the mold component and the one end of the second end preferably arranged such that its edge is visible in a plan view of the underside of the mold component. A plan view of the front side of the molded component therefore shows a shape that is substantially similar to a parallelogram. As a result, the joining of the mold components is particularly stable and easy to implement.
Des Weiteren ist es bevorzugt vorgesehen, dass ein erster Normalabstand zwischen Oberseite des Formbauelementes und der Kante der zur Oberseite nächstgelegenen Stufe der ersten Stirnseite kleiner ist, als ein zweiter Normalabstand zwischen Oberseite und der Kante der Stufe der zweiten Stirnseite.Furthermore, it is preferably provided that a first normal distance between the upper side of the molded component and the edge of the uppermost step of the first end face is smaller than a second normal distance between the upper side and the edge of the step of the second end face.
In einer weiteren bevorzugten Ausführungsvariante ist es vorgesehen, dass ein dritter Normalabstand zwischen Unterseite des Formbauelementes und der Kante der zur Unterseite nächstgelegenen Stufe der ersten Stirnseite kleiner ist, als ein vierter Normalabstand zwischen Unterseite und der Kante der Stufe der zweiten Stirnseite, dass des Weiteren die Tiefe der zur Oberseite nächstgelegenen Stufe der ersten Stirnseite geringer ist, als jene Tiefe der zur Unterseite nächstgelegenen Stufe der ersten Stirnseite, und dass die Tiefe der zur Unterseite nächstgelegenen Stufe der ersten Stirnseite bevorzugt gleich der Tiefe der Stufe der zweiten Stirnseite ist, wobei die Tiefen der Stufen entlang jeweils derselben Parallelen zur Vorderseite gemessen werden.In a further preferred embodiment, it is provided that a third normal distance between the underside of the mold component and the edge of the bottom is smaller than a fourth normal distance between the bottom and the edge of the step of the second end side, further that the depth of the top nearest step of the first end side is lower than the depth of the closest to the bottom step of the first end face , and in that the depth of the first endmost step of the first end face is preferably equal to the depth of the second end face step, the depths of the steps being measured along each of the same parallels to the front side.
Jedes dieser Merkmale trägt dazu bei, die Geometrie des Formbauelements, insbesondere die Geometrie der Stirnseiten des Formbauelements näher zu bestimmen und somit die Verzahnung beim Verlegen sukzessive zu verbessern, um eine besonders dichte und mechanisch stabile Verbindung der Formbauelemente zu ermöglichen, insbesondere bei Aneinanderreihung der Formbauelemente die Ausbildung einer Vergussfuge an der durch die Formbauelemente gebildeten Oberfläche zu gewährleisten, ohne dadurch den stirnseitigen Kontakt zwischen einzelnen Formbauelementen zu unterbinden.Each of these features helps to more closely determine the geometry of the molded component, in particular the geometry of the front sides of the mold component and thus successively improve the teeth during installation, to allow a particularly dense and mechanically stable connection of the mold components, in particular when juxtaposing the mold components to ensure the formation of a Vergussfuge on the surface formed by the mold components, without thereby preventing the frontal contact between individual mold components.
Um zylindrische Schachtbauwerke besonders einfach an Verkehrsflächen anbinden zu können, sind die Vorder- und Rückseite der Formbauelemente in einer bevorzugten Ausführungsvariante zueinander parallel, und bilden jeweils einen Abschnitt eines Zylindermantels aus. Letzteres Merkmal trägt dazu bei, dass durch entsprechende Aneinanderreihung von Formbauelementen ein in sich geschlossener Kreisring aus Formbauelementen geschaffen werden kann.In order to connect cylindrical shaft structures to traffic areas in a particularly simple manner, in a preferred embodiment, the front and rear sides of the molded components are parallel to one another, and each form a section of a cylinder jacket. The latter feature contributes to the fact that a self-contained circular ring of molded components can be created by appropriate juxtaposition of molded components.
Zwecks Schaffung hoher mechanischer Belastbarkeit, ist es vorgesehen, dass ein erfindungsgemäßes Formbauelement allseitig geschlossen ist. Ein geschlossener Aufbau ist darüber hinaus einfach zu realisieren und mit niedrigen Produktionskosten verbunden.For the purpose of providing high mechanical strength, it is provided that a mold component according to the invention is closed on all sides. A closed structure is also easy to implement and low production costs.
In einer weiteren Ausführungsform der Erfindung ist es vorgesehen, dass die Oberseite des Formbauelements aus dem erstarrten Gussasphalt herausragende, grobkörnige Elemente, vorzugsweise Hartsplitt, aufweist, um die Oberfläche rau und griffig zu gestalten. Dadurch kann die Unfallgefahr bei Beschreiten oder sonstigem Überqueren des Formbauelements zusätzlich reduziert werden.In a further embodiment of the invention, it is provided that the top of the molded component from the solidified mastic asphalt outstanding, coarse-grained elements, preferably hard chippings, in order to make the surface rough and handy. This can additionally reduce the risk of accidents when walking or otherwise crossing the mold component.
Die der Erfindung zugrundeliegende Aufgabe wird des Weiteren durch eine Anordnung zur Anbindung eines Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche gelöst, wobei die Anordnung eine Mehrzahl an erfindungsgemäßen Formbauelementen umfasst, welche das Schachtbauwerk vollständig umgebend zwischen diesem und der Verkehrsfläche angeordnet sind, wobei die erste Stirnseite eines Formbauelements die zweite Stirnseite eines anderen Formbauelements aus der Mehrzahl der Formbauelemente zumindest entlang eines Abschnitts oder einer Kante kontaktiert und mit einem Verbindemittel verbunden ist und die Vorderseiten der Mehrzahl der Formbauelemente über ein weiteres Verbindemittel mit dem Schachtbauwerk vorzugsweise dem Schachtrahmen verbunden sind und die Rückseiten der Mehrzahl der Formbauelemente über ein zusätzliches Verbindemittel mit der Verkehrsfläche verbunden sind.The problem underlying the invention is further solved by an arrangement for connecting a shaft structure to the traffic area surrounding the shaft structure, wherein the arrangement comprises a plurality of mold elements according to the invention, which are arranged completely surrounding the shaft structure between this and the traffic area, wherein the first end face a mold component, the second end face of another mold component of the plurality of mold members is contacted at least along a portion or edge and connected to a connecting means and the front sides of the plurality of mold members are connected via a further connecting means to the manhole structure preferably the manhole frame and the rear sides of Most of the mold components are connected via an additional connection means with the traffic area.
Indem vorzugsweise der Kontakt zwischen den beiden Stirnseiten zweier einander über diese kontaktierenden Formbauelemente über eine Stirnfläche der zur Oberseite nächstgelegenen Stufe der ersten Stirnseite und eine Stirnfläche der Stufe der zweiten Stirnseite erfolgt, wird eine besonders formschlüssige und stabile Verbindung der Formbauelemente möglich.By preferably the contact between the two end faces of two contacting one another via these mold components via an end face of the top nearest the first end face and an end face of the stage of the second end side, a particularly positive and stable connection of the mold components is possible.
Bei den genannten Verbindemitteln handelt es sich in einer besonders bevorzugten Ausführungsvariante der Erfindung um handelsübliche Heißbitumenvergussmasse mit polymermodifiziertem Bitumen. Dieses ist für die dichte Verbindung der Formbauelemente besonders gut geeignet, da es über wasserabweisende Eigenschaften verfügt, in einfacher Art und Weise heiß in Fugen gegossen werden kann und diese anschmelzend und dichtend verschließt, aber auch gute mechanische Eigenschaften aufweist, wie sie für die Verbindung von Formbauelementen miteinander notwendig sind.In a particularly preferred embodiment of the invention, the above-mentioned bonding agents are commercially available hot bitumen casting compounds with polymer-modified bitumen. This is for the dense Connection of the mold components particularly well suited because it has water-repellent properties, can be cast in a simple manner hot in joints and this melting and sealing closes, but also has good mechanical properties, as they are necessary for the connection of mold components together.
Die der Erfindung zugrundeliegende Aufgabe wird des Weiteren durch ein Verfahren zur Anbindung eines Schachtbauwerks an eine das Schachtbauwerk umgebende Verkehrsfläche gelöst, das folgende Schritte umfasst:
- vorzugsweises Bestreichen der Oberflächen von zur Unterseite nächstgelegenen Stufen der ersten Stirnseiten mehrerer Formbauelemente mit Bitumenemulsion, welche im kalten Zustand aufgebracht wird

- vergießen von im Zuge der Verlegung zwischen den Formbauelementen (1a,...n) entlang der Stirnfläche entstehenden Vergussfugen sowie den zwischen den Formbauelementen und der Verkehrsfläche bzw. dem Schachtrahmen entstehenden Zwischenräumen mit Verbindemitteln, vorzugsweise Heißbitumenvergussmasse
- preferably coating the surfaces of bottom-nearest steps of the first faces of a plurality of bitumen emulsion molded components applied in the cold state
- laying a plurality of mold components around the manhole frame of the manhole structure, surrounding it completely, the first end face of a first mold component contacting a second end face of a second mold component of the plurality of mold members at least along a portion or an edge
- Shedding of in the course of laying between the mold components (1a, ... n) along the end face resulting Vergussfugen as well as between the mold components and the traffic area or the manhole frame resulting gaps with connecting means, preferably Heißbitumenvergussmasse
Auf diese Weise erfolgt die Realisierung der Anbindung möglichst einfach, rasch, stabil und kosteneffizient. Bei der Bitumenemulsion handelt es sich vorzugsweise um eine Bitumen-Wasseremulsion mit 40% bis 60%iger Sättigung, die besonders bevorzugt Emulgatoren aufweisen.In this way, the implementation of the connection is as simple, fast, stable and cost-effective.
