Problems solved by technology

However, especially in the field of bridges, the disadvantage of the measures known so far is the cost per kilometer, because the roadway is in this respect multiple elastically supported, that is, on the one hand in the area of ​​the bridge bearings and On the other hand, between the track body and the bridge bottom structure or bridge support device

Embodiment Construction

[0013] FIG. 1 shows a schematic view of a part of a vehicle bridge according to the invention, including its basic elements. The figure shows a bridge pier 1 on which parts of the support device 3 , 3 ′ are supported. The bridge pier 1 itself is supported on a substructure, not shown here, and the components of the bearing devices 3 , 3 ′ shown in the figures are supported on the bridge pier 1 in a known manner via bridge supports 2 , 2 ′. Arranged above the support devices 3 , 3 ′ is a superstructure 6 for the roadway, which is, for example, a track arrangement of the road, which is delimited on both sides by railings or barriers.

[0014] As is known, the bridge bearings 2 , 2 ′ have a horizontal elasticity through which the horizontal movement of the bridge pavement or the support device 3 , 3 ′ takes place, said horizontal movement occurring in particular due to temperature changes. However, unlike what is known from the prior art, no elastomeric bearings are involved in ...

Abstract

The invention relates to a solution for damping vibrations and structure-borne noise that occur on vehicle bridges when traveled upon by vehicles. A vehicle bridge, which is comprised, in essence, of a substructure, bridge piers (1), bridge bearings (2, 2') and a supporting framework (3, 3') and which is equipped with means for damping the structure-borne noise occurring when a vehicle is traveling on the bridge, comprises modified bridge bearings that are provided in the form of one or more both horizontal as well as vertically elastic steel springs (4, 4, 4', 5, 5').

Description

technical field [0001] The invention relates to a solution for damping the vibrations and solid-borne sound that occur on vehicle bridges when vehicles pass by. The invention preferably relates to damping vibration and structure-borne sound on railway bridges, but is not limited thereto. Since the concept of vibration basically also includes structure-borne sound, the following description of the damping behavior of the bridge according to the invention also always refers to structure-borne sound, if only vibration is mentioned. Background technique [0002] In the vicinity of the track installation and here, in particular on bridges, when rail vehicles pass by, enormous vibration and noise loads arise due to the vibrations and structure-borne sound transmitted via the track body to the foundation. In addition, the strong vibration loads on the bridge are also due to its support. According to the prior art, bridges and thus railway bridges are generally supported by means ...
