Abstract

The shaft component, in particular, in the form of a concrete shaft ring (1) comprises partially embedded, strip like load-bearing elements (4) which are uniformly distributed close to the ring circumference (2), consist of a plastic mater-ial with creep properties, and have a cross section with a protruding, triangular head portion (6).

Description

Die Erfindung betrifft ein Schachtbauteil, insbesondere einen Schachtring aus Beton oder dgl., mit einem oberen und einem unteren, ringförmigen Rand und mit mehreren an einem derselben in Abstand voneinander gleichmäßig am Umfang verteilt angeordneten, streifenförmigen Lastaufnahmeelementen aus Kunststoff, die beim Betonieren des Bauteiles jeweils mit einem Fußteil in den Rand eingebettet sind und jeweils mit einem Kopfteil über dessen Stimfläche so vorstehen, daß sich die Kopfteile im Einbauzustand an der Stirnfläche des Randes eines angrenzenden Bauteiles abstützen und die benachbarten Stirnflächen übereinander angeordneter Bauteile einen geringen Abstand voneinander haben.The invention relates to a shaft component, in particular a shaft ring made of concrete or Like., With an upper and a lower, annular edge and with several at one the same spaced apart evenly distributed on the circumference, strip-shaped plastic load-bearing elements that are used when concreting the component are each embedded in the edge with a foot part and each with a head part above the end face protrude so that the head parts are in the installed state on the end face support the edge of an adjacent component and the adjacent end faces components arranged one above the other have a small distance from one another.

Bei der Herstellung von Kanalisationsschächten und ähnlichen Tiefbauwerken werden mehrere ringförmige vorgefertigte Schachtbauteile aus Beton aufeinandergesetzt. Die einzelnen Schachtbauteile sind dabei mit oberen und unteren Rändern versehen, die komplementär zueinander ausgebildet sind und so ineinandergreifen, daß eine konzentrische Ausrichtung der Schachtringe erfolgt. Herstellungsbedingt sind die Stirnflächen an den Rändern der Schachtringe nicht genau plan. Eine Kraftübertragung der übereinander angeordneten Schachtringe würde dann nur an denjenigen Stellen erfolgen, wo sich die Strinflächen berühren, während an den übrigen im Abstand voneinander angeordneten Bereichen der Stimflächen keine Kraftübertragung erfolgt. Durch das hohe Eigengewicht der übereinander angeordneten Schachtringe und eventuelle Verkehrs- und Erdlasten könnten Punktbelastungen auftreten, die zu einem Ausplatzen des Betons, zu Rißbildungen und schlimmstenfalls zu einer Zerstörung des Schachtringes führen können. Die US 4,592,674 beschreibt ein Schachtbauteil mit einer oberen, nach innen gewandten Schulter, entlang der ein ringförmiger Kunststoffeinsatz verläuft. Dieser Kunststoffeinsatz ist einerseits in den Schachtbauteil verankert und weist andererseits hervorstehende Rippen auf. Über die Eigenschaften des Kunststoffes findet sich in der Druckschrift keine Angabe. Die Nachteile dieses Schachtringes sind identisch mit den oben diskutierten Nachteilen. In the manufacture of sewer shafts and similar civil engineering structures several ring-shaped prefabricated manhole components made of concrete. The individual shaft components are provided with upper and lower edges that are complementary to each other and interlock so that a concentric Alignment of the manhole rings is done. The end faces on the The edges of the manhole rings are not exactly flat. A power transmission of one another arranged manhole rings would then only take place at those places where the Touch stripes while spaced apart from the others No power transmission takes place in the areas of the end faces. Due to the high weight of the stacked manhole rings and possible traffic and earth loads Point loads occur that cause the concrete to crack, cracking and in the worst case, can lead to the destruction of the manhole ring. US 4,592,674 describes a manhole component with an upper, inwardly facing shoulder, along the an annular plastic insert runs. This plastic insert is on the one hand in the Manhole component anchored and on the other hand has protruding ribs. About the Properties of the plastic are not given in the publication. The disadvantages this shaft ring are identical to the disadvantages discussed above.

Deshalb hat man bei Schachtbauteilen, insbesondere Schachtringen der eingangs genannten Art (EP 0759 488 A 1) an dem unteren Rand dieses Schachtringes mehrere Streifen aus Hartelastumer mit rechteckigem Querschnitt gleichmäßig am Umfang verteilt so angeordnet, daß ein Teil ihres Querschnittes in den unteren Rand eingebettet ist und ein anderer Teil über die Stirnfläche des unteren Randes vorsteht. Hierbei sollen insbesondere drei Streifen aus Hartelastomer rotationssymmetrisch, gleichmäßig beabstandet angeordnet sein. Da sich hierbei die Streifen um einen größeren Teil des Umfanges erstrecken, kann es trotz der elastischen Nachgiebigkeit der Streifen zu örtlichen Punktbelastungen kommen, wenn beispielsweise die dem Streifen gegenüber liegende Stirnfläche des benachbarten Schachtringes fertigungsbedingte Unebenheiten aufweist. Bedingt durch den gleichbleibenden rechteckigen Querschnitt der Streifen haben diese nur ein geringes Ausgleichsvermögen. Außerdem ist ein Elastomer ungeeignet, denn es drückt sich bei wechselnder Verkehrsbelastung mehr oder weniger zusammen, so daß die übereinander gesetzten Schachtringe eine federnde Säule bilden.Therefore, one has at the beginning of manhole components, in particular manhole rings mentioned type (EP 0759 488 A 1) at the lower edge of this shaft ring several Strips of hard elastic with a rectangular cross-section evenly around the circumference distributed so that part of its cross-section is embedded in the lower edge and another part protrudes over the end face of the lower edge. Here should in particular three strips of hard elastomer rotationally symmetrical, even spaced apart. Since the stripes cover a larger part of the Extend circumference, it may be despite the elastic compliance of the strips local point loads come when, for example, opposite the strip lying end face of the adjacent manhole ring, production-related bumps having. Due to the constant rectangular cross-section of the stripes they have little compensation. It is also an elastomer unsuitable, because it changes more or less when traffic loads change together so that the stacked manhole rings form a resilient column.

Der Erfindung liegt nun die Aufgabe zugrunde ein Schachtbauteil, insbesondere einen Schachtring au Beton oder dgl. der eingangs erwähnten Art zu schaffen, bei welchem die Lastaufnahmeelemente so ausgestaltet sind, daß Punktbelastungen der Ränder der Schachtbauteile und auch ein elastisches Nachgeben des gesamten Schachtes vermieden werden.The invention is based on the object of a shaft component, in particular one To create manhole ring made of concrete or the like. Of the type mentioned, in which the load bearing elements are designed so that point loads on the edges of the Manhole components and also an elastic yielding of the entire manhole avoided become.

Dies wird nach der Erfindung dadurch erreicht, daß das Kopfteil jedes Lastaufnahmeelementes als Leiste ausgebildet ist, deren Querschnitt zum freien Ende des Kopfteiles hin verjüngt und daß das Lastaufnahmeelement aus einem Kunststoff mit kriechenden Eigenschaften besteht.This is achieved according to the invention in that the head part of each Load-bearing element is designed as a bar, the cross section of which to the free end the headboard tapers and that the load-bearing element made of a plastic with creeping properties.

Wichtig hierbei ist, daß die Kopfteile als relativ schmal Leisten ausgebildet sind und sich ihr Querschnitt zum freien Ende hin verjüngt. Hierdurch wird erreicht, daß mit steigender Zusammenpressung der Kopfteile jeweils ihr lasttragender Querschnitt, d.h. ihre Tragfähigkeit zunimmt. Je stärker das Kopfteil zusammengedrückt wird, desto größer wird seine Fläche auf welcher die Kraftübertragung erfolgt. Es wird damit ein progressives Ausgleichsverhalten erreicht. Außerdem wird auch erreicht, daß möglichst viele der am Rand gleichmäßig verteilten Lastaufnahmeelemente, die infolge von Fertigungsungenauigkeiten unterschiedlich zusammengedrückt werden, zum Tragen kommen. Damit können Punktbelastungen und ihre nachteilige Folgen wirksam vermieden werden. Unter einem Kunststoff mit kriechenden Eigenschaften wird hier ein Werkstoff verstanden, der sich unter Druckbelastung plastisch bis zu einem gewissen Grad verformt, dann aber unter dieser Belastung seine Form nicht weiter verändert. Nach vollständiger Entlastung kann ein derartiger Kunststoff sehr langsam wieder annähernd in seine ursprüngliche Form zurückkehren. Im Gegensatz zu einem Elastomer ist jedoch derartiger Kunststoff nicht elastisch. Derartiger Kunststoff gehört zu der Gruppe der Thermoplaste (Plastomere).It is important here that the head parts are designed as relatively narrow strips and their cross-section tapers towards the free end. This ensures that with increasing compression of the head parts each their load-bearing cross-section, i.e. their bearing capacity increases. The more the head part is pressed together, the more the area on which the power transmission takes place becomes larger. It becomes one progressive balancing behavior achieved. It is also achieved that as possible many of the load-bearing elements evenly distributed along the edge, which are the result of Manufacturing inaccuracies are compressed differently to bear come. Point loads and their disadvantageous consequences can thus be effective be avoided. Here is a plastic with creeping properties Understand material that is plastically under pressure to a certain extent Degree deformed, but then its shape does not change further under this load. After complete relief, such a plastic can very slowly again approximately return to its original form. In contrast to one However, such a plastic is not elastic. Such plastic is one to the group of thermoplastics (plastomers).

Der aus Beton oder ähnlichen Formmassen bestehende Schachtring 1 weist einen unteren, ringförmigen Rand 2 und einen komplementär dazu ausgebildeten, nicht dargestellten oberen Rand auf. Wie dieser obere Rand ausgestaltet ist, ist aus Figur 3 ersichtlich, wo auch der obere Rand 3 eines benachbarten Schachtringes dargestellt ist. Am unteren Rand 2 sind mehrere, nämlich bei diesen Ausführungsbeispielen 8, Lastaufnahmeelemente 4 aus Kunststoff in Abstand voneinander gleichmäßig am Umfang verteilt angeordnet.. In Figur 4 bis 6 ist eines dieser streifenförmigen Lastaufnahmeelemente näher dargestellt. Dieses Lastaufnahmeelement 4 weist ein Fußteil 5 und ein als schmälere Leiste ausgebildetes Kopfteil 6 auf. Das Fußteil 5 wird, wie es in Figur 2 und 3 dargestellt ist beim betonieren in den unteren Rand 2 des Schachtringes 1 eingebettet. Damit es dort sicher gehalten ist, weist das Fußteil 5 zweckmäßig einen sich zum Kopfteil 6 hin verjüngenden, schwalbenschwanzförmigen Querschnitt auf. Das Fußteil kann beispielsweise eine Länge von ca. 100 mm und einen Übergang zum Kopfteil 6 eine Breite B von etwa 30 mm aufweisen. Das Lastaufnahmeelement ist so mit seinem Fußteil 5 in den unteren Rand 2 eingebettet, daß das Kopfteil 6, wie es aus Figur 2 ersichtlich ist, über die Stirnfläche 2 a des Randes 2 vorsteht.The shaft ring 1 made of concrete or similar molding compounds has one lower, annular edge 2 and a complementary, not shown upper edge. How this upper edge is designed is shown in FIG. 3 can be seen where the upper edge 3 of an adjacent shaft ring is also shown. At the lower edge 2 there are several, namely in these exemplary embodiments 8, Load-bearing elements 4 made of plastic evenly spaced from each other Arranged circumferentially distributed .. In Figure 4 to 6, one of these is strip-shaped Load bearing elements shown in more detail. This load-bearing element 4 has a Foot part 5 and a head part 6 designed as a narrower bar. The foot part 5 is as shown in Figures 2 and 3 when concreting in the lower edge 2 of the Manhole ring 1 embedded. So that it is held securely there, the foot part 5 expediently a dovetail-shaped tapering towards the head part 6 Cross section on. The foot part can be, for example, a length of approximately 100 mm and one Transition to the head part 6 have a width B of approximately 30 mm. The Load-bearing element is embedded with its foot part 5 in the lower edge 2, that the head part 6, as can be seen from Figure 2, over the end face 2 a of the edge 2 stands out.

Der Querschnitt des leistenförmigen Kopfteiles 6 verjüngt sich zu dessen freien Ende 6a hin. Um dies zu erreichen kann das Kopfteil zweckmäßig einen im wesentlichen dreieckförmigen Querschnitt aufweisen. Dabei ist die Höhe h des Kopfteils zweckmäßig etwa halb so hoch, wie seine Breite b an der Basis des Kopfteiles. Diese Breite b kann etwa 14 mm betragen, wobei die Länge des Kopfteiles 6 a der Basis etwa 80 mm beträgt. Die Breite b des Kopfteiles 6 an seiner Basis ist etwa halb so breit wie die Breite B des Fußteiles 5 in diesem Bereich.The cross section of the strip-shaped head part 6 tapers towards its free end 6a there. In order to achieve this, the headboard can be essentially one have triangular cross-section. The height h of the head part is appropriate about half the width b at the base of the headboard. This width b can be about 14 mm, the length of the head part 6 a of the base about 80 mm is. The width b of the head part 6 at its base is about half as wide as that Width B of the foot part 5 in this area.

Das Lastaufnahmeelement 4 besteht aus einem Kunststoff mit kriechenden Eigenschaften, der sich unter Druckbelastung plastisch verformt, jedoch nicht elastisch nachgiebig ist. Trotzdem kehrt ein derartiger Kunststoff nach vollständiger Entlastung nach längerer Zeit in seine ursprüngliche Form zurück. Als Kunststoff wird zweckmäßig PVC (Polyvinylchlorid) verwendet.The load-bearing element 4 consists of a plastic with creeping Properties that deform plastically under pressure, but not elastic is compliant. Nevertheless, such a plastic returns after complete relief after a long time back to its original shape. As a plastic expediently PVC (polyvinyl chloride) used.

In Figur 2 und auch in den Figuren 4 bis 6 ist das Lastausgleichselement 4 in seiner ursprünglichen Form dargestellt. Werden zwei Schachtringe übereinandergesetzt, dann stützen sich die Lastaufnahmeelemente 4 mit ihren Kopfteilen 5 auf der Stirnfläche 3a des oberen Randes 3 des darunter liegenden, angrenzenden Schachtringes 1 ab. Fertigungsungenauigkeiten werden hierbei dadurch ausgeglichen, daß die Kopfteile 6 der verschiedenen Lastaufnahmeelemente 4 mehr oder weniger zusammengedrückt werden. Da die Fertigungsungenauigkeiten maximal 5 mm betragen, kommen bei einer Höhe h der Kopfteile 6 von 7 mm dabei alle Lastaufnahmeelemente zum tragen. Dank der Verjüngung des Querschnittes der Kopfteile 6 zu ihren freien Enden 6 a hin, haben die Lastaufnahmelemente 4 ein progressives Verhalten. Mit steigender Zusammendrückung nimmt der lasttragende Querschnitt der Kopfteile 6 zu.In Figure 2 and also in Figures 4 to 6, the load balancing element 4 is in its shown original form. If two manhole rings are placed on top of each other, then the load-bearing elements 4 are supported with their head parts 5 on the end face 3a the upper edge 3 of the underlying, adjacent shaft ring 1. Manufacturing inaccuracies are compensated for by the fact that the head parts 6 of the various load bearing elements 4 more or less compressed become. Since the manufacturing inaccuracies amount to a maximum of 5 mm, a Height h of the head parts 6 of 7 mm, all load bearing elements to be carried. thanks the taper of the cross section of the head parts 6 towards their free ends 6 a the load suspension elements 4 a progressive behavior. With increasing The compression of the load-bearing cross section of the head parts 6 increases.

Ähnliches kann auch dann erreicht werden, wenn das Kopfteil 6' wie es in Figur 7 dargestellt ist, im Querschnitt im wesentlichen trapezförmig ist.The same can also be achieved if the head part 6 'as in FIG. 7 is shown, is substantially trapezoidal in cross section.

Die Erfindung ist nicht nur bei Schachtringen sondern auch bei anderen Schachtbauteilen anwendbar wie z.B. Schachthälsen oder ggf. auch bei Auflageringen. Es ist auch denkbar die Lastaufnahmeelemente jeweils am oberen Rand der Schachtbauteile anzuordnen. In diesem Fall müßte jedoch auch der obere Rand eines Schachtunterteiles mit Lastaufnahmeelementen versehen werden.The invention is not only in manhole rings but also in others Manhole components applicable such as Manhole necks or, if necessary, also with support rings. It is also conceivable for the load-bearing elements in each case at the upper edge of the Arrange shaft components. In this case, however, the upper edge of a Lower part of the manhole be provided with load-bearing elements.
