Definitions

  • the invention relates to a building with a reinforcing element made of high-strength concrete to increase the puncture resistance specified in the preamble of claim 1 genus.
  • the invention has for its object to provide a building of the generic type, whose creation is simplified.
  • the reinforcing element consists of a plurality of prefabricated segments, which are arranged in a ring.
  • the individual segments are easier to manufacture, transport and handle than a one-piece, correspondingly larger reinforcing element. It has been shown that it is also possible to achieve a significant increase in the puncture resistance with a reinforcing element comprising a plurality of segments arranged in a ring shape. The individual segments allow, to a certain extent, an adaptation of the size of the reinforcing element.
  • circumferentially adjacent segments have a distance from each other and are connected to each other via a material whose strength is lower than that of the high-strength concrete of the reinforcing element.
  • the adjacent segments are in particular connected to one another via the material of the plate, in particular via in-situ concrete.
  • the distance between adjacent segments is advantageously low.
  • the distance between adjacent segments at the opening is advantageously at most 10 cm, in particular at most 5 cm.
  • the distance between adjacent segments over the entire length of the gap formed between the adjacent elements is not more than 10 cm.
  • the adjacent longitudinal sides of the segments are advantageously provided with a suitable contour which activates the multiaxial compressive strength of the potting material.
  • At least one reinforcing element of the reinforcing element protrudes into the gap formed between two adjacent segments.
  • reinforcing elements of both adjacent segments protrude into the joint and overlap to achieve high strength.
  • At least two segments of the reinforcing element are formed identically.
  • Particularly advantageous designs result when the reinforcing element is made up of at most two different segments.
  • Particularly advantageous all segments of a reinforcing element are identical.
  • the plate has a punching shear reinforcement.
  • a high puncture resistance can be achieved if at least one segment has a groove into which protrudes a reinforcing element of the punching reinforcement.
  • the reinforcing element is in particular a push anchor.
  • the arrangement in the groove also results in a simplified production, since the reinforcing element can be pre-positioned on the reinforcing element.
  • the reinforcing element of the punching reinforcement is advantageous in the groove with a material whose strength is lower than that of the high-strength concrete of the reinforcing element is fixed.
  • the reinforcing element with a different material than the material of the plate, in particular with flowable mortar shed.
  • the mortar may be mortar normal strength or high-strength grout.
  • the at least one groove is formed closed on the side facing the support. This simplifies the positioning of the punching reinforcement. At the same time, the strength of the reinforcing member is not reduced in the area immediately surrounding the opening. A good integration of the reinforcing element in the plate is achieved if at least one reinforcing element of the punching reinforcement is arranged outside of the reinforcing element.
  • the plate advantageously has a lower reinforcement. High strength is achieved when the lower reinforcement extends above the reinforcing element.
  • the lower reinforcement is advantageously provided adjacent to the edge region of the reinforcing element with a Friedkröpfung. However, it can also be provided that the lower reinforcement extends in suitable recesses of the reinforcing element. A Aufkröpfung the lower reinforcement can then be omitted.
  • the edge region of the reinforcing element is advantageously beveled. This results in a favorable force curve and a good force distribution in the plate.
  • the term "concrete” is used as a generic term and generally refers to a building material, which is formed as a mixture of a binder and an aggregate, regardless of the grain size. Also mortar falls under the used here generic term “concrete”.
  • the concrete may contain additives and additives.
  • High-strength concrete refers to a concrete from a compressive strength of 55 N / mm 2 .
  • the high-strength concrete of the reinforcing element is in particular an ultra-high-strength concrete (UHFB or UHPC (ultra high performance concrete)) having a compressive strength of more than 130 N / mm 2 , in particular more than 200 N / mm 2 .

  • the structure advantageously has a support connected to the plate, which is arranged in the region of the opening of the reinforcing element.
  • a support connected to the plate, which is arranged in the region of the opening of the reinforcing element.
  • the reinforcing element introduced from the support into the plate forces can be well received and distributed.
  • the opening is advantageously arranged centrally in the reinforcing element. However, it may also be an off-center arrangement of the opening be advantageous, for example, in confined spaces or to adapt to the male loads.

  • the plate 2 also has a punching shear, which is formed in the embodiment of a plurality of thrust anchors 5.
  • the thrust armature 5 are formed in the embodiment as a double-headed anchor. Other types of punching reinforcement, for example in the form of filigree or the like, however, are possible.

  • the strength of the potting material is advantageously smaller than that of the reinforcing element 4.
