Roadway spiral for the entry and/or departure of motor vehicles in multistorey car parks, underground garages or the like

摘要

A roadway spiral for the entry and/or departure of motor vehicles in multistorey car parks, underground garages or the like is specified, which spiral is produced exclusively from prefabricated elements, thus allowing a considerable saving in costs and time to be achieved in comparison with conventional production by the in-situ concrete process. The roadway spiral is made up of identically designed prefabricated roadway slabs (3), for which cantilever arms (2) integrally bonded to prefabricated supports (1) serve as bearers. By rigid coupling of the roadway slabs to the supports in the region of their bearing on the cantilever arms, the spiral acts statically as a ring and holds the supports firmly in place horizontally. To absorb horizontal forces, individual supports are connected shear-resistantly to shear walls. <IMAGE>
