Definitions

  • the invention relates to a reinforced concrete column.
  • support describes rod-shaped pressure element, the larger cross-sectional dimension of which is four times does not exceed the smaller dimension.
  • the invention has for its object a maximum payload at the smallest Develop cross-sectional reinforced concrete column, if necessary can also be delivered as a finished part.
  • this object is achieved by a reinforced concrete column, consisting of high-strength concrete and one made of high-strength steel Longitudinal reinforcement with a steel head or base plate non-positively connected by gluing or spot welding are, and with a stirrup or spiral reinforcement.
  • high-strength concrete denotes concrete of strength classes C55 / 67 - C100 / 115 with a dry bulk density of over 2,100 kg / m 3 , but at most 2,600 kg / m 3 (according to DIN 1045-2) .
  • high-strength concretes are those that exceed the strength class C 50/60 according to DIN 1045, for example a C 80/95.
  • high-strength concretes with a very low water / cement value of generally less than 0.40 are produced.
  • Such concretes are impermeable to liquid water, and the diffusion of water vapor is very slow and depends on the balance. Depending on the ambient conditions, in particular the relative air humidity, a moisture equilibrium is established in the concrete, so that the concrete generally contains more than 3% by weight of water.
  • the high-strength steel to be used according to the invention is preferably not cold-drawn and has a quality> S 500.
  • Steel S 835/1030 according to DIN EN 10138, part 4 is preferably used; this has a nominal tensile strength of at least 1030 N / mm 2 . According to the invention, therefore, no structural steels are used, but steels of greater strength. High-strength ribbed longitudinal bars but also smooth steels can be used.
  • this can be done by adding steel fibers or chips Brittle fracture behavior of the high-strength concrete can be improved. You can these steel fibers or chips have a length of 25 - 60 mm.
  • the concrete is an addition of plastic fibers contains by softening, melting or decomposing at temperatures can form a capillary system from 150 - 300 ° C. It is already known and by DE 42 20 274 C2 and EP 0 575 886 B1 Protection provided by the addition of such fibers in components made of high-strength Emphasize, especially reinforced concrete components, the destructive flaking under To prevent fire exposure.
  • the capillary system mentioned essentially linear capillary with a diameter between 10 and 100 m and a length between 5 and 35 mm.
  • a support according to the invention can extend over one or more storey heights have extending length. It is useful if one in each case at the level of a storey, possibly with one Filling material filled bag is provided.
  • the supports according to the invention are preferably used as prefabricated elements concreted and compacted horizontally. Basically, however, is also a manufacture possible as in-situ concrete column.
  • the high-strength concrete applies to both the load capacity as well as in the event of fire together with the high-strength steel Carries or survives loads or stresses from fire.
  • the invention also detects columns that do not have connecting reinforcement, but only be fixed in place with a oarlock.
  • Figure 1 shows a reinforced concrete column 1 with a longitudinal reinforcement made of high strength Steel.
  • Longitudinal bars 2 are provided, that of outer brackets 3 and inner ones Brackets 4 are encompassed, which are somewhat denser in the area of the support ends are arranged as above the central longitudinal section of the support 1.
  • the concrete cover is identified by reference number 5.
  • the longitudinal bars 2 have a steel head plate 6 at the ends of the supports or base plate 7 non-positively connected by gluing or spot welding.
  • An oar 8 can also be attached to fix the position.
