Definitions

  • the invention relates to a method and device for damping structures against vibrations, in particular earthquakes, traffic vibrations and impact sound.
  • the object of the invention is a method and device for increasing the damping of structures. This increases earthquake security and reduces vibrations in the building caused by machines, traffic vibrations and impact noise.
  • the object of the invention is achieved by damped steel inserts in concrete.
  • the damping inserts are divided into segments of length e (Fig. 1). The optimum is between segment length l, cross section F, circumference U and
  • the damping inserts are not completely severed, but receive incisions, notches or arches at a distance j ⁇ .
  • Such interventions bring about a reduction in the spring stiffness, so that the force flow does not run within the steel insert when vibrating, but is transmitted from one segment part to the other via the damping layer.
  • conventional structural steel is surrounded with a damping plastic jacket.
  • a vibrating movement leads to plastic deformations in the plastic jacket and thus to dampening of building vibrations.
  • Fig. 1 shows a basic version of the damping insert. It consists of steel segments 1 with the length of the radius R and the elastic modulus E. This is covered with a sheet metal sleeve 2. There is a damping material 3, for. B. high polymers, tars, solid lubricants, with a sliding module G and the thickness d. The sheet metal sleeve 2 has crankings 5 and is roughened on the surface in order to ensure a non-positive connection with the surrounding concrete. - If the concrete reinforced with a damping insert is exposed to a vibration load, the vibration force is transmitted to the steel segments 1 via the sheet metal sleeve 2 and damping material 3.
  • a damping material 3 for. B. high polymers, tars, solid lubricants
  • Fig. 2 is essentially analogous to Fig. 1.
  • the damping insert consists of steel segments 11, which are not completely separated, but only have a reduced spring constant compared to tension due to cuts 14 and also cause an interruption in the flow of force.
  • arches 24 subdivide into steel segments 21. These are again surrounded by a damping coating 23 and a sheet metal jacket 22 with offsets 25.
  • Fig. 4 is comparable to the embodiment of Fig. 3.
  • the damping insert is again by arches 34, which have a reduced spring constant against tensile load in. individual steel segments 31 divided.
  • the steel segments 31 are surrounded by a damping plastic 33. If the damping insert is poured into concrete, plastic deformations occur in the damping layer 33.
  • the formulas given in FIG. 1 apply analogously to the dimensioning of the damping layer 33 and the length, cross section and modulus of elasticity of the steel segments 31.
  • the length of the steel segments 31 is the distance between the arches 34.
  • the damping insert is divided into individual steel segments 41 by conical tapering 44. These are again surrounded by a damping material 43, while the whole is enclosed by a sheet metal jacket 42.
  • the damping insert similar to conventional structural steel, is cast into the concrete.
  • the sheet metal jacket 42 is provided with knobs 45.
  • Fig. 6 differs from Fig. 5 by dispensing with a protective sheet metal jacket.
  • the damping insert is again divided into individual steel segments 51, which are surrounded by a damping material 53, by tapering 54.
  • the cushioning insert is poured directly into concrete.
  • the damping insert consists of a conventional, continuous structural steel rod 61. This is surrounded by a damping material 63 and enclosed by a sheet metal jacket 62. -
  • the damping insert is formed analogously to FIG. 7 by an essentially conventional structural steel rod 71, which is surrounded by a damping material 73 in the manner of a film.
  • This consists of a plastic resistant to concrete or a bitumen layer.
  • the embodiment according to FIG. 9 represents a flat damping element. It consists of sheet metal squares 81, which are decoupled by means of crankings 84 from tensile stresses.
  • the sheet metal squares are provided with a damping material 83 and are located on the bottom or top of the wall to be damped. A fixed connection is ensured by hooks 86.
  • the damping element can be understood as an "anti-drumming covering". The dimensioning is analogous to FIG. 1, the segment length 1 and the side length corresponding to the sheet metal squares 81. -
  • the damping inserts according to Fig. 1 - 8 are poured into the concrete in the same way as the structural steel reinforcement.
  • a reinforcement level of 1 - 3% o is sufficient to double the internal damping.
  • the damping effect is greatest when the damping insert is arranged as far as possible from the neutral fiber in the edge areas and at stress concentrations in corners. It is also possible to attach the damping inserts to the outside - even afterwards. It is only necessary to ensure a good non-positive connection.
  • FIG. 10 a further introduction is shown in FIG. 10.
  • the damping insert changes from the top to the bottom of the wall. Such an arrangement results in higher loads and thus also higher damping.
  • the flanged seam can also be formed as a positive connection between the metal jacket and concrete.
  • a spiral circulation of the flanged seam can also be advantageous for this purpose.
