The Chain Bridge Neuperlach is a pedestrian and cycle path bridge in Munich - Neuperlach , which facilitates the connection between the center of Neuperlach and the residential area north of Ständerstraße .
location
The way to the bridge begins on Adenauerring between the Generali Versicherung buildings . From there, the bridge crosses Ständerstrasse, a four-lane expressway at a height of almost 5 m, the route of which was laid out as a 42 m wide motorway feeder and runs in a lowered bed bordered by a noise barrier to the north. The bridge then crosses the underground car park of the surrounding apartment blocks, which cannot be seen from the outside, with a long ramp and ends at Plettstrasse.
description
The light and filigree steel bridge is a rare example of a modern chain bridge . The chains of flat steel eye poles hanging from three pairs of pylons support a flat and wide bridge deck that rests on narrow supports. The load-bearing structure is held in light blue, while the tie rods used for stiffening and their joints are painted in a matt red. The railing, which is separated from the pylons and carrying chains, is made of stainless steel tubing, as are the carrying brackets connected to it, on which the lighting hangs. The bridge is wide enough that a heavy Unimog can cross it to clear snow. It has an asphalt surface.
In contrast to most suspension bridges , the Neuperlach Chain Bridge does not have pylons in the sense of piers that extend right up to the top and that support the entire bridge structure. Rather, on the concrete foundations there are slim, round pendulum supports with small roller bearings that support the bridge deck. The bridge deck consists of double T-beams on the two long sides, which are welded to the plate reinforced with trapezoidal ribs . The hexagonal recesses in the side members, which are probably only used for optical purposes, are precisely matched to the trapezoidal profiles. The bridge deck is an orthotropic plate running from anchor block to anchor block with spans of 9.50 m, 19 m, 19 m and 9.50 m. The bridge has the required clearance height of 4.70 m across the entire carriageway. The bridge deck is 4.20 m wide, the sidewalk is 3.50 m wide.
Slightly slimmer pylons stand above the pendulum supports on the side longitudinal beams, the tips of which are connected by double T-beams, which have the same hexagonal recesses as the longitudinal beams. The chains suspended between these pylons consist of six double flat bars, which are connected to one another with bolted stainless steel joints. The joints are also connected to the pylons or the longitudinal girders by tie rods, which subdivide all sections of the suspension structure into triangles and thereby give the bridge the necessary rigidity.
The ramp at the northern end of the bridge also rests on pendulum supports, the position of which had to be coordinated with the conditions of the underground car park below.
The bridge was planned by Richard J. Dietrich , Traunstein, and built between 1990 and 1992.
