The cut out is irremovably connected to the base and has at least one guide channel (11) having a vertical section and an intermediate horizontal section (11') to receive a projecting pin on the entry aid. The cut out is positioned in a preformed recess (16) for a soil catcher. Claims include a manhole for the shaft.

Description

Die Erfindung betrifft einen Schachtrahmen nach dem Oberbegriff des Anspruchs 1 und eine Schachtabdeckung nach Anspruch 9.The invention relates to a manhole frame according to the preamble of claim 1 and a manhole cover according to claim 9.

Schächte erfüllen wichtige wassertechnische Aufgaben von der Wassergewinnung bis hin zur Abwasserpumpstation. Somit sind diese Bauwerke entscheidender Bestandteil einer zuverlässigen Wasserversorgung und Abwasserentsorgung. Dabei geht man meist von einer langjährigen Nutzungsdauer aus. In regelmäßigen Abständen sind Begehungen zu Kontroll- oder Wartungsarbeiten notwendig. Zum Schutz des Bedienungspersonals gibt es eindeutige Regelwerke und Vorschriften. Doch fehlt es bei alten Schächten oft schon an den wichtigsten Grundlagen. Nicht nur Unfallgefahren lauern, auch die eigentliche Funktion oder sogar die Substanz des Bauwerks ist oft gefährdet. Meist erfolgt der Einstieg vertikal von oben. Hier schreiben die Gesetzgeber eine sogenannte Einstiegshilfe vor. An dieser kann sich der Arbeiter festhalten, um den ersten Schritt in den Schacht zu machen. An abwassertechnischen Anlagen müssen oberhalb der Einstiegstellen zu Steigeisen-Gängen oder Schachtsteigleitern geeignete Haltevorrichtungen vorhanden sein.Manholes fulfill important water engineering tasks from water extraction to the wastewater pumping station. Thus, these structures are a crucial component of a reliable water supply and sanitation. It is usually based on a long-term useful life. At regular intervals, inspections for inspection or maintenance work are necessary. To protect the operating personnel, there are clear rules and regulations. But old shafts often lack the most important foundations. Not only dangers of accidents lurk, also the actual function or even the substance of the building is often endangered. Mostly the entry is vertical from above. Here, the legislators prescribe a so-called boarding assistance. At this the worker can hold on to take the first step into the shaft. At wastewater treatment plants suitable holding devices must be present above the entry points to crampons aisles or shaft risers.

Bei herkömmlichen Straßenschächten sind keine geeigneten Haltevorrichtungen vorhanden. Daher werden im Schachtinneren meist sogenannte Einsteckhülsen nachgerüstet, in die der Schachtarbeiter dann eine Art Einstiegshilfe in Form einer Stange mit Griff einstecken kann. Diese Hülsen müssen an der Schachtinnenwand befestigt werden. Auch wenn die Hülsen verhältnismäßig günstig sind, entstehen durch ihren Einbau oft sehr viel höhere Kosten, da es meist schwierig ist, die Hülsen in den vielmals maroden Schachtwänden sicher zu verankern. Die Montagekosten können daher leicht das drei- bis vierfache der Kosten für die Einsteckhülse ausmachen. Alternativ gibt es daher transportable Einstiegshilfen, die ohne eine feste Halterung beim Begehen eines Schachts verwendet werden können. Diese entsprechen in ihrem Außenabmessungen der Schachtabdeckung, da sie in den Schacht eingesetzt und an seinen Innenwandungen verspannt werden. Derartige Einstiegshilfen sind extrem teuer und sperrig. Sie nehmen so viel Platz ein, daß die Einstiegsöffnung oftmals zu klein wird. Außerdem benötigt es relativ viel Zeit, bis die Einstiegshilfe selbst für jeden Einsatz montiert und demontiert ist.In conventional road shafts, no suitable holding devices are available. Therefore, mostly so-called insertion sleeves are retrofitted in the shaft interior, in which the manhole then a kind of boarding aid in the form of a rod with handle can plug. These sleeves must be attached to the shaft inner wall. Even if the sleeves are relatively cheap, their installation often causes much higher costs, since it is usually difficult to anchor the sleeves securely in the often rutted shaft walls. The cost of assembly can therefore easily account for three to four times the cost of the insert sleeve. Alternatively, there are therefore portable boarding aids that can be used without a solid support when walking a shaft. These correspond in their outer dimensions of the manhole cover, as they are inserted into the shaft and clamped on its inner walls. Such boarding aids are extremely expensive and bulky. They occupy so much space that the manhole often becomes too small. It also takes a relatively long time for the boarding aid itself to be assembled and dismantled for each job.

Die Erfindung befaßt sich daher mit dem Problem, hier Abhilfe zu schaffen.The invention therefore deals with the problem of remedy this situation.

Das erfindungsgemäße Problem wird durch einen Schachtrahmen mit den Merkmalen des Anspruchs 1 sowie durch einen Straßenkontrollschacht mit den Merkmalen des Anspruchs 9 gelöst.The problem of the invention is achieved by a manhole frame with the features of claim 1 and by a road control shaft with the features of claim 9.

Da die Schachtabdeckungen der Straßenkontrollschächte einem deutlichen Verschleiß unterliegen und daher ohnehin in gewissen Abständen ausgetauscht werden müssen, sieht die Erfindung vor, eine feste Aufnahme zur Befestigung einer Einstiegshilfe direkt am bzw. im Schachtrahmen vorzusehen. Vorzugsweise ist die Aufnahme mit dem Rahmengrundkörper unlösbar verbunden, insbesondere bereits in dessen Geometrie integriert. Besonders vorteilhaft ist es, wenn die Aufnahme so ausgestaltet ist, daß die bisherigen üblichen Einstiegshilfen in Form von mit Griffen versehenen Stangen weiterbenutzt werden können.Since the manhole covers of the road control shafts are subject to significant wear and therefore must be replaced at certain intervals anyway, the invention provides to provide a fixed receptacle for attaching a boarding aid directly on or in the manhole frame. Preferably, the receptacle is permanently connected to the frame body, in particular already integrated in its geometry. It is particularly advantageous if the receptacle is configured such that the hitherto conventional access aids in the form of rods provided with handles can be used further.

Die erfindungsgemäße Ausgestaltung mit Aufnahme für eine Einstiegshilfe ist weder auf ein besonderes Material, noch auf eine besondere Form des Schachtrahmens beschränkt. Sie kann sowohl bei rein gußeisernen Schachtrahmen als auch bei solchen aus Beton/Guß zur Anwendung kommen. Auch können die Schachtrahmen sowohl rund als auch eckig ausgestaltet sein.The inventive design with a receptacle for a boarding aid is not limited to a special material, nor to a particular shape of the manhole frame. It can be used both in purely cast iron manhole frame as well as in concrete / cast iron. Also, the manhole frame be designed both round and square.

Der in Fig. 1 dargestellte Schachtrahmen besteht aus einem Rahmengrundkörper 1, der mit einem Kragen 2 bündig mit der Straßen- oder Gehwegoberfläche abschließt und mit Wandungen 3 in den Kanalschacht eintaucht. Unterhalb der Wandungen 3 befindet sich die nicht dargestellte Schachtwand oder eventuell Ausgleichsringe. In dieser Schachtwand oder den Ausgleichsringen wurden bei herkömmlich ausgestatteten Straßenkontrollschächten die Hülsen zur Befestigung der Einstiegshilfe angebracht. Entsprechend der Erfindung hingegen weist der Schachtrahmen selbst eine Aufnahme 4 zur Befestigung einer Einstiegshilfe auf.The manhole frame shown in Fig. 1 consists of a frame body 1, which is flush with a collar 2 flush with the road or pavement surface and immersed with walls 3 in the manhole. Below the walls 3 is the shaft wall, not shown, or possibly compensating rings. In this shaft wall or the compensating rings, the sleeves for attaching the boarding aid were mounted in conventionally equipped street control shafts. According to the invention, however, the manhole frame itself has a receptacle 4 for attaching a boarding aid.

Eine übliche Einstiegshilfe ist in Fig. 2 dargestellt. Sie besteht aus einer Stange 5 mit vier Haltegriffen 6. Am unteren Ende der Stange 5 weist die Einstiegshilfe zwei vorspringende Zapfen 7 auf, mittels der die Einstiegshilfe gegen unbeabsichtigtes Herausziehen gesichert bzw. verriegelt werden kann. In Fig. 3 ist das unsere Ende einer anderen Einstiegshilfe abgebildet, wobei oberhalb der Zapfen 7 eine Anschlagscheibe 8 fest mit der Stange 5 verbunden ist, so daß die Stange 5 nicht weiter als beabsichtigt in der entsprechenden Aufnahme herabrutschen kann.A common boarding aid is shown in Fig. 2. It consists of a rod 5 with four handles 6. At the lower end of the rod 5, the boarding aid on two protruding pin 7, by means of which the boarding aid can be secured or locked against unintentional withdrawal. In Fig. 3, this is our end of another boarding aid shown, above the pin 7, a stop plate 8 is fixedly connected to the rod 5, so that the rod 5 can not slide further than intended in the corresponding recording.

Die genauere Ausgestaltung der Aufnahme 4 ist in den Fig. 4 bis 6 dargestellt. Sie besteht aus einer im wesentlichen zylinderförmigen Ausnehmung 10, die sich in einem verdickten Bereich der Wandung 3 des Rahmengrundkörpers 1 senkrecht nach unten hin erstreckt. In der Innenwand der Ausnehmung 10 sind Führungskanäle 11 ausgespart, die die Zapfen 7 der Einstiegshilfe aufnehmen. Die Führungskanäle 11 haben einen im wesentlichen vertikalen Verlauf mit einer Zwischenstrecke 11', die sich im wesentlichen horizontal erstreckt. Die Einstiegshilfe kann mit ihren Zapfen 7 in die in Fig. 4 mit durchgezogenen Linien gezeigten Führungskanäle 11 eingesetzt werden. In dieser Position läßt sich die Einstiegshilfe ca. 40 mm tief absenken. Dann wird die Einstiegshilfe im Uhrzeigersinn um 60 Grad verdreht, so daß ihre Zapfen 7 den waagerechten Zwischenstrecken 11' der Führungskanäle 11 folgen. Anschließend sackt die Einstiegshilfe mit ihren Zapfen 7 den Führungskanälen 11 folgend nochmals um ca. 40 mm ab. Die Zapfen 7 befinden sich dabei in der in Fig. 4 gestrichelt dargestellten Position. Die Einstiegshilfe ist damit sicher festegelegt und kann von dem Revisionspersonal verwendet werden.The more detailed embodiment of the receptacle 4 is shown in FIGS. 4 to 6. It consists of a substantially cylindrical recess 10, which extends in a thickened region of the wall 3 of the frame body 1 vertically downwards. In the inner wall of the recess 10 guide channels 11 are recessed, which receive the pin 7 of the boarding aid. The guide channels 11 have a substantially vertical course with an intermediate section 11 ', which extends substantially horizontally. The boarding aid can be used with their pins 7 in the guide channels 11 shown in Fig. 4 by solid lines become. In this position, the boarding aid can be lowered about 40 mm deep. Then the boarding aid is rotated clockwise by 60 degrees, so that their pins 7 follow the horizontal intermediate sections 11 'of the guide channels 11. Subsequently, the boarding aid sank with its pin 7 following the guide channels 11 again by about 40 mm. The pins 7 are located in the position shown in dashed lines in Fig. 4. The boarding aid is thus securely determined and can be used by the inspection staff.

Wie in den Fig. 5 bis 7 dargestellt, hat die Aufnahme 4 am unteren Ende der Ausnehmung 10 eine Öffnung 12, die sich durch die Wandung 3 des Rahmengrundkörpers 1 hindurch erstreckt. Durch diese Öffnung 12 kann eventuell in die Aufnahme 4 eindringender Schmutz und Wasser ablaufen, so daß die Aufnahme funktionsfähig bleibt und vor Verrottung und einem sich Zusetzen geschützt wird.As shown in FIGS. 5 to 7, the receptacle 4 at the lower end of the recess 10 has an opening 12 which extends through the wall 3 of the frame body 1 therethrough. Through this opening 12 may possibly run into the receptacle 4 penetrating dirt and water, so that the recording remains functional and is protected from rotting and clogging.

Fig. 8 zeigt eine alternative Ausgestaltung des Schachtrahmens, bei dem zusätzlich zu der Öffnung 12 zwei weitere Öffnungen 13 in den Rahmengrundkörper 2 eingebracht sind. Hierbei handelt es sich bevorzugt um vorgebohrte Löcher, die bei Bedarf auf die erforderliche Größe aufgebohrt und mit einem Innengewinde versehen werden können, an dem dann eine Steigleiter angesetzt werden kann. Dies erhöht die flexible Einsetzbarkeit des Schachtrahmens für verschiedene örtliche Gegebenheiten erheblich. Sollten im Schacht selbst keine Stufen oder Tritte vorhanden sein, können diese durch eine Steigleiter nun leicht am Schachtrahmen dauerhaft aber auswechselbar festgelegt werden.8 shows an alternative embodiment of the manhole frame, in which, in addition to the opening 12, two further openings 13 are made in the frame base body 2. These are preferably pre-drilled holes, which can be drilled on demand to the required size and provided with an internal thread on which then a riser can be attached. This considerably increases the flexible applicability of the manhole frame for various local conditions. If there are no steps or steps in the shaft itself, they can now be easily and permanently fixed to the manhole frame by means of a ladder.

In den Fig. 9 bis 11 ist eine weitere Variante des erfindungsgemäßen Schachtrahmens dargestellt. Fig. 9 zeigt einen entsprechenden Schachtrahmen in perspektivischer Darstellung. Dabei handelt es sich um einen Beton/Guß-Rahmen, der wie dargestellt teilweise aus Beton 15 besteht. Bei diesem Schachtrahmen ist die Aufnahme 4 nicht wie bei der vorherigen Ausführungsform an einem separaten Ort innerhalb des Rahmengrundkörpers angeordnet, sondern in eine der vier Auflageaussparungen 16 integriert, die der Aufnahme eines Schmutzfängers dienen. Der nicht dargestellte Schmutzfänger entspricht im wesentlichen einem großen, runden "Sieb", das mit vier seitlich jeweils gegenüber angeschweißten Haltern in die Auflageaussparungen 16 eingelegt werden kann. Um die Auflageaussparung 16 gleichzeitig entsprechend der Erfindung als Aufnahme für eine Einstiegshilfe verwendbar zu machen, sind aus den seitlichen Wänden 17 einer der Auflageaussparungen 16 Führungskanäle 11 ausgenommen, die in ihrer Ausgestaltung und Geometrie denen des vorherigen Ausführungsbeispiels der Erfindung entsprechen können.FIGS. 9 to 11 show a further variant of the manhole frame according to the invention. Fig. 9 shows a corresponding manhole frame in a perspective view. This is a concrete / cast frame, like shown partially made of concrete 15. In this manhole frame, the receptacle 4 is not arranged as in the previous embodiment at a separate location within the frame body, but integrated into one of the four support recesses 16, which serve to receive a mudflap. The strainer, not shown, substantially corresponds to a large, round "sieve", which can be inserted with four laterally opposite welded holders in the support recesses 16. In order to make the support recess 16 simultaneously usable according to the invention as a receptacle for a boarding aid 16 guide channels 11 are excluded from the side walls 17 of the support recesses, which may correspond in their design and geometry to those of the previous embodiment of the invention.

Zusammenfassend ermöglicht der erfindungsgemäße Schachtrahmen bzw. eine entsprechende Schachtabdeckung mit Deckel und ggf. Schmutzfänger es, sämtliche noch nicht vorschriftsgemäß mit Befestigungseinrichtungen für Einstiegshilfen ausgestattete Revisionsschächte sukzessive den Vorschriften entsprechend auszurüsten, immer dann, wenn ohnehin der Schachtrahmen getauscht werden muß. Die erfindungsgemäßen Schachtrahmen bieten damit eine sichere Befestigungsmöglichkeit für Einstiegshilfen, ohne sich im Preis nennenswert von herkömmlichen Schachtrahmen zu unterscheiden. Auch können die üblicherweise bei Städten und Gemeinden vorhandenen Einstiegshilfestangen weiterhin verwendet werden.In summary, the manhole frame according to the invention or a corresponding manhole cover with lid and possibly strainer makes it possible to furnish all the inspection shafts not yet properly equipped with fastening devices for boarding aids according to the regulations, whenever the manhole frame has to be exchanged anyway. The manhole frame according to the invention thus provide a secure mounting option for boarding aids, without being significantly different in price from conventional manhole frame. It is also possible to continue to use the entry-level temporary mallets that are usually available in cities and towns.
