Description
Die Erfindung bezieht sich auf einen Tragrost für Füükörperlürme, bestehend aus in konzentrischen Ringreihen, in jeder Ringreihe unter sich austauschbar gleichen, gegen die Steine benachbarter Reihen versetzt angeordneter, zu einem kugelabschnittsförmigen Bogengewölbe zusammengesetzten ringsektorförmigen Roststeinen.The invention relates to a support grid for Fükörperlürme, consisting of in concentric Rows of rings, interchangeably the same in each row of rings, offset from the stones in adjacent rows arranged, to a spherical segment-shaped arched vault assembled annular sector-shaped Rust stones.
Bei einer Tragrostausbildung dieser Art (»Kleines Handbuch des Säureschutzbaues« von Friedrich Karl F a I c k e, 1966, Seiten 385 und 386) sind die Roststeine T-förmig ausgebildet und in jeder Ringreihe mit ihren Flanschen in der Weise initeinander verbunden und durch Bildung der Ringreihe miteinander verspannt, daß das eine Ende des Flansches eine konkave und das andere eine konvexe Wölbung aufweist. Dabei liegen dann konvexe und konkave Wölbung benachbarter Steine aufeinander. Da bei diesem Tragrost infolge der geschilderten einseitigen Einspannung der Flansche die T-Stege beim Betrieb erheblichen Spannungen und Pumpbelastungen unterworfen sind, müssen diese Stege verhältnismäßig stark bemessen werden, und es ist aus den gleichen Gründen nicht möglich, sie länger als etwaIn a support grid of this type ("Kleines Handbuch des Säureschutzbaues" by Friedrich Karl F a I c k e, 1966, pages 385 and 386) the grate stones are T-shaped and in each row of rings with their Flanges connected to one another in such a way and braced together by forming the row of rings that one end of the flange has a concave and the other has a convex curvature. Thereby lie then convex and concave curvature of adjacent stones on top of each other. Since this support grid as a result of described one-sided clamping of the flanges, the T-bars during operation considerable stresses and Are subjected to pumping loads, these webs must be dimensioned relatively strong, and it is off the same reasons do not allow them to last longer than about

Die Aufmauerung des Rostes wird, wie in Fig. 1

?00 mm zu machen, mit dem Ergebnis, daß schon für einen verhältnismäßig kleinen Rostdurchmesser von
4 m neun bis zehn Steinringreihen benötigt werden. Es ergibt sich ferner, daß die Belastung der Steine,
insbesondere die Scherbeanspruchungen, es nicht erlauben, über einen Rostdurchmesser von etwa 5 m
hinauszugehen. Infolge der großen Zahl von Steinreihen und der Stärke der Steinstege wird auch nur ein
Durchgangsquerschnitt von etwa 33 bis 35% erreicht.The brick-up of the grate is facilitated, as indicated by dash-dotted lines in Fig. 1, by arched, curved radial beams 7 on which concentrically arranged ring rails or pairs of ring rails 8, 9 and 10 are placed.
? 00 mm, with the result that nine to ten rows of stone rings are required for a relatively small grate diameter of 4 m. It also emerges that the loading of the stones, in particular the shear stresses, does not allow them to go beyond a grate diameter of about 5 m. Due to the large number of rows of stones and the thickness of the stone bridges, only a passage cross-section of around 33 to 35% is achieved.
Der Erfindung liegt die Aufgabe zugrunde, für die Tragroste der anfangs erwähnten Bauweise einen Roststein zu schaffen, der die Bemessung mit kleineren Stegquerschnitten und größeren Steinlängen erlaubt, um neben einer größeren Lebensdauer des gesamten Rosu uich einen besseren Durchgangsquerschnitt zuThe invention is based on the object for the support grids of the construction mentioned at the beginning To create grate that allows dimensioning with smaller web cross-sections and larger stone lengths, in order to achieve a better passage cross-section in addition to a longer service life of the entire Rosuich

Diese Aufgabe wird dadurch gelöst, daß die Roststeine an beiden Längsseiten nach Art eines I-Profils halbovale Ausnehmungen aufweisen und sich mit ihren oberen und unteren Flanschen gegeneinander abstützen. Mit diesen Steinen lassen sich bereits Tragroste von 10 m Durchmesser und einem Durchgangsquerschnitt von 45% erstellen.This object is achieved in that the grate stones on both long sides in the manner of a I-profile have semi-oval recesses and their upper and lower flanges against each other prop up. With these stones, support grids with a diameter of 10 m and a passage cross-section can be created of 45%.
