Abstract
Właz kanałowy zwłaszcza studzienek kanalizacyjnych wykonany w postaci odlewu, zawiera korpus z użebrowaniem wzmacniającym oraz pokrywę, która od góry ma wyprofilowane elementy przeciwpoślizgowe, zaś od spodu wyposażona jest w żebra usztywniające, a ponadto wyposażona jest w otwory montażowe pod blokadę oraz w otwory do podnoszenia pokrywy, charakteryzuje się tym, że właz w całości wykonany jest ze stopu aluminium, przy czym żebra usztywniające pokrywy (2) mają kształt płaskowników usytuowanych prostopadle do spodniej części pokrywy (2) i tworzą przestrzenną kratownicę zamkniętą obwodowym pierścieniem, przy czym kształt kratownicy oparty jest zasadniczo na trójkątach równobocznych, rozmieszczonych na całej powierzchni spodniej pokrywy (2).The channel manhole, especially of sewage manholes made in the form of a cast, contains a body with reinforcing ribs and a cover, which has profiled anti-slip elements from above, and from the bottom is equipped with stiffening ribs, and is also equipped with mounting holes for the blockade and holes for lifting the cover , characterized by the fact that the manhole is made entirely of aluminum alloy, with the stiffening ribs of the cover (2) shaped like flat bars perpendicular to the bottom of the cover (2) and forming a spatial truss closed by a peripheral ring, with the shape of the truss being essentially supported on equilateral triangles, distributed over the entire bottom surface of the cover (2).
