Definitions
- the invention relates to a solution for damping vibrations and structure-borne noise, which occur at vehicle bridges when driving on vehicles. It preferably relates to the damping of vibrations and structure-borne sound at railway bridges, but without being limited thereto.
- bridges In the vicinity of track systems, and in particular on bridges, occurs when driving on track vehicles on a significant vibration and noise pollution transmitted through the track body to the ground vibrations and structure-borne sound.
- the increased vibration load on bridges is due to their storage.
- Bridges, and so also railway bridges are stored in the prior art usually by means of elastomeric bearings.
- the actual task of the bridge bearings is to allow horizontal movements of the bridge carriageway, as they occur as a result of temperature fluctuations.
- the provided for this purpose on the bridges elastomeric bearings are therefore characterized by the fact that they are very elastic horizontally. On the other hand, however, they have a high rigidity in the vertical direction by design.
- such measures include, especially in railway bridges to dampen from the infrastructure, so in this case the transmitted from the tracks to the substructure of the bridge vibrations and thus the structure-borne sound.
- railway tracks are mounted on vertically elastic bearings or supported by spring-mass systems.
- the object of the invention is therefore to provide a solution which makes it possible to effectively dampen vibrations and structure-borne sound on bridges while reducing the structural complexity and cost compared to previously known solutions.
- the object is achieved by a vehicle bridge with the features of the main claim.
- Advantageous embodiments or further developments of the invention are given by the subclaims.
- the stated object is achieved in that the existing essentially of a substructure, bridge piers, bridge bearings and a supporting structure vehicle bridge has modified bridge bearings, which are in the form of one or more both horizontally, as well as vertically elastic steel springs.
- These bridge bearings like conventionally designed bridge bearings, act elastically against horizontal movements or displacements of the bridge supporting body, but moreover, due to their vertical elasticity, simultaneously damp the vibrations occurring during the passage of the bridge and essentially transmitted to the substructure, including structure-borne noise.
- the inventive concept is therefore to use in the construction of bridges, in particular of bridges for vehicular traffic, bridge bearings, which in addition to the required high horizontal elasticity to allow temperature-induced deformation of the bridge also have a high vertical elasticity.
- steel springs made of hot-formed spring steel which have a high vertical elasticity, are also well suited for the realization of bridging bearings, that is, with appropriate design, also have a sufficient for use as bridge bearings horizontal elasticity.
- the use of steel springs for bridge storage it is possible, instead of the otherwise necessary to meet both requirements (allowing horizontal movements of the bridge structure on the one hand and vibration reduction or sound attenuation on the other hand) multi-elastic storage by a simple-elastic storage of the bridge structure and the requirements of the vibration - And to meet body sound attenuation.
- helical compression springs In experiments and modeling helical compression springs have been found to be particularly suitable for the formation of modified bridge bearings proved.
- shape and dimensioning of the helical compression springs used to realize the simple-elastic bearing depend on the particular application. However, it has been found that these should have a wire diameter of more than 5 mm and a spring diameter of over 50 mm with a number of turns of 4 or more.
- barrel springs In addition to ordinary cylindrical helical compression springs barrel springs, funnel springs, truncated cones or feathers of similar geometric shape can be used.
- the object of the invention is, as emphasized, preferably achieved by the use of helical compression springs.
- leaf springs In principle, it is also possible to use leaf springs, torsion springs or other springs made of steel, provided that they are designed so that they have both the required horizontal and vertical elasticity.
- inventive principle of the modification of bridge bearings and their training by steel springs is of course fundamentally applicable to bridges of any kind, but is, according to the title of the invention, advantageous in terms of the occurrence of significant vibrations, especially in vehicle bridges.
- Fig. 1 A section of a bridge formed according to the invention in a schematic representation
- Fig. 2 Schematically a helical compression spring used to solve the problem in a sectional view with a longitudinally guided by the spring section.
- Fig. 1 shows a portion of a designed according to the invention vehicle bridge with its essential elements in a schematic representation.
- a bridge pier 1 is shown, on which rest parts of the structure 3, 3 'of the bridge.
- the bridge pier 1 itself rests on a substructure, not shown here.
- the parts of the shown in the figure Structure 3, 3 ' are based, in a conventional manner, on bridge bearings 2, 2' on the bridge pier 1 from.
- the structures 6 are arranged for the routes, which are, for example, track systems of the railway, which are bounded on both sides of the route by a railing or a screen.
- the bridge bearings 2, 2 have, as is known, a horizontal elasticity, by means of which horizontal movements of the bridge carriageway or the supporting structure 3, 3 ', which occur in particular as a result of temperature changes, are made possible.
- the bridge bearings 2, 2 ' are not elastomeric bearings. Rather, the bridge bearings according to the invention by a plurality, in the example shown, cylindrical helical compression springs 4, 4 ', 5, 5' are formed, which in addition to the required horizontal elasticity also have a high vertical elasticity.
- helical compression springs 4, 4 ', 5, 5' are used as bridge bearings 2, 2 '.
- 2 shows the schematic representation of a corresponding helical compression spring 4 used to solve the problem as part of a bridge bearing 2, 2 '.
- This is a helical compression spring 4 made of hot-formed spring steel, in the example of FIG. 10 Turns.
- the bridge bearings 2, 2 'according to FIG. 1 each consist of a group of corresponding helical compression springs 4, 4', 5, 5 '.
- Such a spring 4 has a high vertical elasticity.
- the vertically acting force F z illustrates that force which is registered when driving through the bridge of the vehicles and is connected to a transmission of vibrations and structure-borne noise to the ground.
- the force F x denotes a horizontal force, as it acts, for example, by temperature fluctuations on the bridge bearing 2, 2 ', x designates the caused by this force travel transverse to the spring axis.
