  • the invention relates to a carrier arrangement with a substantially rectilinear carrier arranged between two bearings, which extends along a longitudinal direction and is composed of at least three longitudinally successive segments connected to one another via two top plate joints, namely a middle segment and two outer segments, wherein Bearings are hampered by the displacement in the longitudinal direction.

Abstract

L'invention concerne un ensemble de support pourvu d'un support (2) sensiblement rectiligne disposé entre deux appuis (4, 6). Ledit support s'étend le long d'une direction longitudinale (8) et est composé d'au moins trois segments (10, 12, 14) disposés les uns derrière les autres dans la direction longitudinale (8) et reliés les uns aux autres par deux joints de plaque de recouvrement (22), ces trois segments étant un segment central (10) et deux segments extérieurs (12, 14), et les appuis (4, 6) étant empêchés de se déplacer dans la direction longitudinale (8). L'invention vise à permettre une réduction contrôlée des forces de contrainte thermiques, tout en conservant la fonction de transfert de charge, et tout en ayant une répartition uniforme des forces dynamiques extérieures à l'intérieur de la construction. A cet effet, selon l'invention, le segment central (10) comporte à ses deux extrémités respectivement une plaque de recouvrement de segment central (18), et chacun des deux segments extérieurs (12, 14) comporte à son extrémité orientée en direction du segment central (10) une plaque de recouvrement de segment extérieur (20). La plaque de recouvrement de segment extérieur (20) respective est orientée de manière complémentaire par rapport à la plaque de recouvrement de segment central (18) qui lui est opposée, de telle manière qu'elles forment conjointement un joint de plaques de recouvrement (22). Les deux plaques de recouvrement (18, 20) de chaque joint de plaques de recouvrement (22) sont reliées ensemble par des boulons d'assemblage (28) qui sont guidés à travers des évidements (26) dans les plaques de recouvrement (18, 20). Les évidements (26) dans au moins une des plaques de recouvrement (18) de chaque joint de plaques de recouvrement (22) se présentent sous la forme de trous oblongs (34). Les deux joints de plaques de recouvrement (22) sont inclinés en sens inverse par rapport à un plan normal sur la direction longitudinale (8), et les trous oblongs (34) sont disposés et orientés de telle manière que, lors d'une dilatation ou d'une contraction thermique des segments (10, 12, 14), un déplacement latéral du segment central (10) par rapport aux deux segments extérieurs (12, 14) est possible.
