Definitions

  • the invention relates to a land vehicle.
  • the land vehicle is partially made of concrete.
  • a car body and / or a base or chassis of the vehicle can be made at least partially of concrete.
  • the vehicle is partly made of high-strength concrete.
  • w / c 0.25 to 0.35
  • the addition of water is usually 0.5 to 0.7 times the cement mass. This ratio is reduced to values between 0.35 and 0.25 for high-strength concretes. Thus, less water is added to these concretes than is necessary for complete hydration of the cement (w / z ⁇ 0.40).
  • high strength concrete has a strength of 60-180 N / mm 2 .
  • Such a high-strength concrete or a process for its preparation has become known, for example, from CH 473739.
  • the vehicle is at least partially made of ultra-high performance concrete.
  • Ultra-high-performance concrete is understood as meaning a high-strength concrete whose strength is approx. 180 - 230 N / mm2. Recipes for the production of ultra-high performance concretes have become known to the expert in numerous forms and should therefore not be explained in detail here. Ultra-high performance concrete is particularly suitable for highly stressed, wide-stretched components.
  • the dense and homogeneous structure of the high-strength concrete or of the ultra-high-performance concrete with its low capillary pore content guarantees high strength at normal temperature, but may be unfavorable under fire stress.
  • the physically bound water evaporates in the cement stone. If the resulting vapor pressure can not escape through the capillary pores due to the dense structure, it will discharge itself through concrete spalling.
  • made of high-strength concrete parts of the vehicle can be at least partially secured by a near-surface mesh reinforcement or by admixture of Polypropylenfa ⁇ fibers against chipping. In case of fire, the fibers burn or melt and leave behind tubular pores, which reduce the water vapor pressure.
  • the car body of the vehicle is at least partially made of concrete. Since concrete is characterized by a high resistance to corrosion and good shaping properties in the context of the production process, this material is particularly suitable for the production of components of a car body or a lower frame of a rail vehicle.
  • this material is particularly suitable for the production of components of a car body or a lower frame of a rail vehicle.
  • different types of concrete can be used. The choice of the corresponding concrete is determined primarily by the occurring or expected static and dynamic loads which the component made of concrete is subjected to during operation of the vehicle.
  • a particularly favorable variant of the invention further provides that the vehicle is at least partially made of transparent concrete.
  • Transparent concrete refers to a concrete that consists of at least five percent glass fibers. Through the use of transparent concrete for the production of the car body, a very bright car body interior can be realized without additional artificial light sources. Car body walls of transparent concrete can also be actively illuminated by letting the light of an artificial light source be introduced into the glass fibers arranged in parallel.
  • the floor of the Wagenkas ⁇ least of the vehicle is made of concrete.
  • This embodiment of the invention makes it possible, for example in rail vehicles or magnetic levitation trains, to achieve a very great simplification of the production process, since a large number of assembly steps can be saved when laying the floor in comparison to conventional methods.
  • Concrete can also advantageously be used for the manufacture of the undercarriage, since Ultra high-performance concrete is comparable in its strength properties to steel, and load-bearing structures of the underframe can also be manufactured from this material.
  • concrete is also characterized by its low production costs, which can also significantly reduce the production costs of the vehicle.
