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] figure 1 A schematic diagram showing a part of a vehicle bridge constructed according to the present invention, including its basic elements. In the figure, a bridge pier 1 is shown on which some parts of the supporting devices 3, 3'are supported. The pier 1 itself is supported on a substructure not shown here, and the components of the supporting devices 3, 3'shown in the figures are supported on the pier 1 via bridge supports 2, 2'in a known manner. A superstructure 6 for the roadway is arranged on the supporting devices 3, 3', in which, for example, rail equipment related to roads is defined on both sides of the route by railings or baffles.

[0014] The bridge supports 2, 2'have horizontal elasticity as known, through which the horizontal movement of the bridge pavement or the supporting devices 3, 3'can be carried out, and the horizontal movement occurs especially due to temperature changes. However, unlike what is known from the prior art, no elastomeric supports ar...

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 present invention relates to a solution for reducing vibration and structure-borne sound, which appear when vehicles pass by on a vehicle bridge. The present invention preferably relates to reducing vibration and structure-borne sound on railway bridges, but is not limited to this. Since the concept of vibration basically also includes structure-borne sound, the following description of the attenuation performance of the bridge constructed according to the present invention also always refers to structure-borne sound, if only vibration is mentioned. Background technique [0002] In the vicinity of the rail system and here, especially on bridges, when rail vehicles pass by, a large vibration and noise load occurs due to vibrations and structure-borne sound transmitted through the rail body to the foundation. In addition, the strong vibration load on the bridge is also due to its support. According to the prior art, bridges and therefore railway bridges...
