Publication number: 20130075486Abstract: The rail sleeper (10) is provided with a sleeper body (12) comprising one rail contact area (16) on each of the opposing ends thereof, within which the sleeper body (12) is widened. A rail (24) may be fixed in each rail contact area (16) by means of a hold-down element (28) able to grip a rail foot. Each rail contact area (16) comprises three rail contact surfaces (18) adjacent to one another in the extension of the rail (24). At least one hold-down element (28) is disposed between and above at least one partial region of respective adjacent rail contact surfaces (18) of each rail contact area (16). The sleeper body (12) is free of reinforcement elements within each rail contact area (16) on both sides of the intermediate spaces between adjacent rail contact surfaces (18).Type: ApplicationFiled: September 5, 2012Publication date: March 28, 2013Applicant: MSB-MANAGEMENT GMBHInventors: Jürgen Frenzel, Tim Frenzel

Patent number: 7896255Abstract: A track superstructure for a railway on a subgrade inclined transversely to the length thereof, comprises a ballast structure of individual ballast stones, and sleepers embedded in the ballast structure, on which rails may be mounted, the ballast structure comprising load dissipation regions beneath the sleepers, the regions receiving loads acting vertically on the ballast structure via the sleepers when a train rides on the rails and transferring these loads to the subgrade below the ballast structure. This transfer is characterized in that substantially only the voids between the ballast stones within the load dissipation regions of the ballast structure are filled with a foam material, especially a PU polyurethane foam material, for fixing the ballast stones in a stable position, and an elastic drain layer is arranged between the ballast structure and the subgrade.Type: GrantFiled: January 18, 2007Date of Patent: March 1, 2011Assignee: MSB-Management GmbHInventor: Tim Frenzel

Publication number: 20090152368Abstract: The invention relates to a method for introducing a flowable and foamable reaction mixture from the top into a ballast body having sleepers embedded therein, in which method said mixture is introduced into the ballast body laterally of the sleepers, notably preferably depending on the height of the ballast body at the point of application, and in a quantity that is all the larger the more upwards in the ballast body the application point is situated, wherein the mixture is adjusted in such a way that the foam formation process will begin only when the front of the mixture flowing downwards inside the ballast body has reached the bottom side or the region in the vicinity thereof of the ballast body so that the foam formation is carried out within the ballast body from the bottom towards the top.Type: ApplicationFiled: February 12, 2007Publication date: June 18, 2009Applicant: MSB-MANAGEMENT GMBHInventor: Tim Frenzel
