  Schachtabdeckung 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    sternförmigBund-10-verlängert   und durch eine ringförmige   Rippe --12-- unterbrochen,   an welche die Enden der   Rippen --11-- anschliessen,   wobei an ieser Stelle eine Verdickung oder Materialanhäufung - vorgesehen ist, die eine ähnliche   guss-und spannungstechnische   Funktion wie die   Verdickungen --9-- erfüllt.   Die ringförmige Rippe befindet sich somit in einem Abstand von etwa zwei Drittel des Radius von der Mittelachse der Schale. Durch diese Rippe wird eine weitere Materialanhäufung erzielt, welche die Spannungen der unteren Rippn unterbricht. 



   Der Schachtdeckel kann auch ohne Lüftungsöffnungen vorgesehen sein, insbesondere wenn er mit einer Sicherung gegen Abheben bei Hochwasser versehen ist. 



   Anzahl und Höhe der Rippen der Schachtabdeckung richtet sich nach der jeweils zu erwartenden Belastung. In den fest in die Schachtöffnung einzubauenden Rahmen können demnach Abdeckungen verschiedener Tragkraft eingesetzt werden, beispielsweise kann ein vorhandener Deckel geringer Tragkraft ohne jede Umbauarbeit gegen einen solchen grösserer Tragkraft ausgetauscht werden. 



   Die Schachtabdeckung kann in den Rahmen gegebenenfalls unter Zwischenlage einer Dichtung eingelegt werden. 



   Im Rahmen der Erfindung können noch weitere konstruktive Abänderungen vorgenommen

 undPATENTANSPRÜCHE : 
1. Schachtabdeckung, die durch kreuz-oder sternförmig verlaufende Rippen versteift ist, welche entlang des unteren Randes in eine mit Beton ausgefüllte Schale übergehen und an ihrer Kreuzungsstelle einen Bund aufweisen, welcher ebenso wie die Rippen mit der Betonausfüllung abschliesst,

  Manhole cover
 EMI1.1
 

 <Desc / Clms Page number 2>

    Star-shaped collar-10-extended and interrupted by an annular rib --12 - to which the ends of the ribs --11 - adjoin, with a thickening or accumulation of material at this point - which has a similar casting and tensioning function how the thickenings --9-- met. The annular rib is thus at a distance of about two thirds of the radius from the central axis of the shell. This rib creates a further accumulation of material which interrupts the tension in the lower ribs.



   The manhole cover can also be provided without ventilation openings, in particular if it is provided with a safeguard against lifting off in the event of high water.



   The number and height of the ribs of the manhole cover depend on the load to be expected in each case. In the frame to be installed permanently in the shaft opening, covers of different load-bearing capacity can accordingly be used, for example an existing cover with a low load-bearing capacity can be exchanged for such a higher load-bearing capacity without any conversion work.



   The manhole cover can be inserted into the frame, if necessary with the interposition of a seal.



   Further structural changes can be made within the scope of the invention
 EMI2.1
 and PATENT CLAIMS:
1. Manhole cover that is stiffened by ribs running in the shape of a cross or star, which merge along the lower edge into a shell filled with concrete and at their intersection have a collar which, like the ribs, ends with the concrete filling,

Claims (1)

Rand der Rippen (5) zahnstangenartig ausgebildet ist, wobei nur die Zahnflanken (8) mit dem Beton abschliessen. EMI2.3 Unterseite der Schale (1) in an sich bekannter Weise ein mit dem inneren Bund (6) koaxial verlaufender äusserer Bund (10) vorgesehen ist, von dem aus mit den inneren Rippen (5) sich deckende Rippen (11') bis zum Auflagerand (2) übergehen, die durch eine vorzugsweise in einem Abstand von zwei Dritteln des Radius des Deckels von der Mitte desselben entfernte konzentrische Ringrippe (12) unterbrochen sind. EMI2.4 Übergangsstelle der Radialrippen (11') in die Ringrippe (12) eine Verdickung bzw. Materialanhäufung (9') vorgesehen ist. Edge of the ribs (5) is designed like a rack, only the tooth flanks (8) end with the concrete. EMI2.3 The underside of the shell (1) is provided in a manner known per se with an outer collar (10) which runs coaxially with the inner collar (6), from which ribs (11 ') which are congruent with the inner ribs (5) to the support edge ( 2) pass over, which are interrupted by a concentric annular rib (12) which is preferably at a distance of two thirds of the radius of the lid from the center thereof. EMI2.4 At the transition point of the radial ribs (11 ') into the annular rib (12), a thickening or material accumulation (9') is provided.
