Bezeichnung;Designation;
Schachtabdeckungen mit und ohne Scharnieren und Verschlüssen bestehend aus Winke!rahmen und Deckel» Manhole covers with and without labels and locks consisting of angle frame and cover »
1, An die WinkeIrahmen wurden bisher 4kant-3täbe angeschweißt, um als Auflage für die Schachtdeckel zu dienen« Dabei war die Schweißnaht nur an der unteren Seite dieser Stäbe, sodaß bei grösserer Belastung ein unzulässiges Biegemoment eintreten konnte»1 Up to now, 4-sided 3-bar rods were welded to the angle frame in order to serve as a support To serve for the manhole cover «The weld seam was only on the lower side of these bars, so that an impermissible bending moment could occur with greater loads »
'Siehe Skizze Nr. 1'See sketch no.1
2. Das neue Verfahren besteht darin, daß der Rahmen der Schachtabdeckung aus einem Winkelrahmen hergestellt wird, bei dem mehrere Stege in Form eines Bogens herausgedrückt werden, die zur Aufnahme des Deckels dienen. Siehe Skizze Nr. 22. The new method consists in making the frame of the manhole cover an angle frame is produced in which several webs are pushed out in the form of an arch, which serve to accommodate the cover. See sketch no.2
Die Verbesserung besteht darin, daß die Schachtabdeckung nur noch von einem Winkeleisen aufgenommen wird, das keine angeschweißten Stäbe mehr benötigt. Das bedeutet:The improvement is that the manhole cover is only from one Angle iron is added, which no longer requires welded rods. That means:
a) Erheblich erhöhte Sicherheit.a) Significantly increased security.
b) Materialersparnis von ca. 3O/0·b) Material savings of approx. 3O / 0
c) Arbeitsvereinfachung ebenfalls von ca. 3O,3·c) work simplification also of about 3O 3 ·
d) Die aufgeschweißten Stäbe zeigten von innen immer erhebliche Korrosionsschäden, weil diese Stellen nicht gegen Host geschützt werden konnten. Die vorzeitigen Alterungsschäden sind jetzt vermeidbar, nachdem alle Stellen vor Korrosion geschützt werden konnten. Das bedeutet ebenfalls eine Erhöhung des Sicherheitsgrades.d) The welded-on rods always showed considerable corrosion damage from the inside, because these places could not be protected against the host. The premature aging damage can now be avoided after all areas have been protected from corrosion. That also means an increase in the level of security.
e) Die Rahmen sind durch ihregünstigere Bauart erheblich leichter, sodaß sie auch leichter montiert werden können.e) The frames are considerably lighter due to their cheaper design, so they can also be assembled more easily.
