Guideway girder

Abstract

A guideway girder is provided for a vehicle transport system wherein a plurality of the girders are assembled in succession in a direction of travel of a vehicle to form a guideway for the vehicle. The girder is formed by a combination of concrete structural elements, and includes at least one sound isolation element disposed on a surface of at least one of the structural elements.

1 . Guideway girder, in particular for a magnetic levitation transport system ( 100 ), for forming a guideway with a number of girders ( 2 ) that are successively assembled in the direction of travel, with an upper girder section ( 12 ), in particular a top chord ( 12 ), possibly with a lower girder section ( 15 ), in particular a bottom chord ( 15 ) and at least one supporting section ( 13 ,  14 ), in particular a web ( 13 ,  14 ) below the upper girder section ( 12 ), characterized by at least one sound insulation element ( 7 ,  8 ) located in the area of the upper girder section ( 12 ) and/or of the lower girder section ( 15 ) and/or of the (at least one) supporting section ( 13 ,  14 ).  
     
     
         2 . Guideway girder as in  claim 1 , characterized by a hollow cross-sectional configuration, whereby the cavity ( 16 ) is delimited toward the top by the upper girder section ( 12 ), laterally by a supporting section ( 13 ,  14 ) on either side and toward the bottom by a lower girder section ( 15 ).  
     
     
         3 . Guideway girder as in  claim 1  or  2 , characterized by an installation on one or several pillars ( 5 ) imbedded in the ground.  
     
     
         4 . Guideway girder as in one of the preceding claims, characterized in that the faces of the supporting sections ( 13 ,  14 ) of girders ( 2 ) following each other successively in the direction of the guideway and which are across from each other are essentially connected to each other.  
     
     
         5 . Guideway girder as in one of the preceding claims, characterized in that sound insulation elements ( 7 ,  8 ) are installed on the inside and/or outside of the supporting sections ( 13 ,  14 ), on the bottom and/or top of the upper girder section ( 12 ) and/or on the top of a lower girder section ( 15 ).  
     
     
         6 . Guideway girder as in one of the preceding claims, characterized in that the (at least one) sound insulation element ( 7 ,  8 ) is essentially flat in shape and at least partially covers in the manner of a lining the (at least one) upper girder section ( 12 ) and/or the lower girder section ( 15 ).  
     
     
         7 . Guideway girderas in one of the preceding claims, characterized in that at least one sound insulation element ( 8 ) is provided with two flat segments ( 8   a ,  8   b ) that are at an angle to each other.  
     
     
         8 . Guideway as in one of the preceding claims, characterized in that several sound insulation elements ( 7 ,  8 ) are installed one next to the other in the direction of travel.  
     
     
         9 . Guideway girder as in one of the preceding claims, characterized by a design as a bivalent guideway, e.g. for magnetic levitation transport trains as well as for conventional trains.  
     
     
         10 . Utilization of a tabular sound insulation element for installation on a guideway girder ( 2 ) installed or that can be installed essentially above ground, with an upper girder section ( 12 ), possibly a lower girder section ( 15 ) and with at least one supporting section ( 13 ,  14 ), in particular a guideway girder ( 2 ) as in one of the previous claims.  
     
     
         11 . Utilization of a sound insulation element as in  claim 10 , characterized in that it is used to line free surfaces of the (at least one) supporting section ( 13 ,  14 ) of the upper girder section ( 12 ) and/or of the lower supporting section ( 15 ).  
     
     
         12 . Utilization of a sound insulation element as in  claim 10  or  11 , characterized in that in addition advertising elements are attached to the sound insulation elements ( 7 ,  8 ), in particular billboards and/or illuminated publicity.
