Abstract
Description
Die Erfindung betrifft eine Stahlbeton-Stütze.The invention relates to a reinforced concrete column.
Gemäß DIN 1045-1 Ziffer 3.1 (24) beschreibt die Bezeichnung "Stütze" ein stabförmiges Druckglied, dessen größere Quer schnittsabmessung das Vierfache der kleineren Abmessung nicht übersteigt.According to DIN 1045-1 number 3.1 ( 24 ), the term "support" describes a rod-shaped pressure element whose larger cross-sectional dimension does not exceed four times the smaller dimension.
Der Erfindung liegt die Aufgabe zugrunde, eine höchste Traglas ten beim kleinsten Querschnitt aufnehmende Stahlbeton-Stütze zu entwickeln, die gegebenenfalls auch als Fertigteil angeliefert werden kann.The invention is based, a highest Traglas the task reinforced concrete column supporting the smallest cross-section develop, which may also be delivered as a finished part can be.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Stahlbeton- Stütze, bestehend aus hochfestem Beton und einer aus hochfestem Stahl bestehenden Längsbewehrung, die an den Stützenenden mit einer stählernen Kopf- bzw. Fußplatte durch Anklebung oder Punktschweißung kraftschlüssig verbunden sind, und mit ei ner Bügel- bzw. Wendelbewehrung. According to the invention, this object is achieved by a reinforced concrete Support consisting of high-strength concrete and one of high-strength Steel existing longitudinal reinforcement using the column ends a steel head or foot plate by gluing or spot welding are positively connected, and with egg ner stirrup or spiral reinforcement.
Gemäß DIN 1045-1 Ziffer 3.1 (7) bezeichnet "hochfester Beton" einen Beton der Festigkeitsklassen C55/67-C100/115 mit einer Trockenrohdichte über 2.100 kg/m3, höchstens aber 2.600 kg/m3 (nach DIN 1045-2). Nach DIN 1045 versteht man unter hochfesten Betonen solche, die hinsichtlich ihrer Festigkeit über die Fe stigkeitsklasse C 50/60 nach DIN 1045 hinausgehen, z. B. einen C 80/95. Um die erforderliche hohe Festigkeit des Zementsteins zu erreichen, werden hochfeste Betone mit einem sehr geringen Wasser/Zement-Wert von im allgemeinen unter 0,40 hergestellt. Solche Betone sind für flüssiges Wasser undurchlässig, und die Diffusion von Wasserdampf erfolgt sehr langsam und ist gleichge wichtsabhängig. In Abhängigkeit von den Umgebungsbedingungen, insbesondere von der relativen Luftfeuchte, stellt sich im Beton ein Feuchtegleichgewicht ein, so dass der Beton in der Regel mehr als 3 Gew.-% Wasser enthält.According to DIN 1045-1 number 3.1 ( 7 ), "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) . According to DIN 1045, high-strength concretes are those that go beyond their strength class C 50/60 according to DIN 1045, e.g. B. a C 80/95. In order to achieve the required high strength of the cement block, 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 takes place very slowly and is weight-dependent. 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.
Der erfindungsgemäß einzusetzende hochfeste Stahl ist vorzugs weise nicht kaltgereckt und weist eine Güte < S 500 auf. Vor zugsweise wird Stahl S 835/1030 gemäß DIN EN 10138, Teil 4, ein gesetzt; dieser hat also eine Nennzugfestigkeit von zumindest 1030 N/mm2. Erfindungsgemäß werden somit keine Baustähle, son dern Stähle größerer Festigkeit eingesetzt. Es können hochfeste gerippte Längsstäbe aber auch glatte Stähle eingesetzt werden.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, but steels of greater strength are used. High-strength ribbed longitudinal bars but also smooth steels can be used.
Erfindungsgemäß kann durch einen Zusatz von Stahlfasern oder Spänen das Sprödbruchverhalten des hochfesten Betons verbessert werden. Dabei können diese Stahlfasern oder Späne eine Länge von 25-60 mm aufweisen.According to the invention, by adding steel fibers or Chips improve the brittle fracture behavior of the high-strength concrete become. These steel fibers or chips can have a length of Have 25-60 mm.
Ferner kann es zweckmäßig sein, wenn der Beton einen Zusatz von Kunststofffasern enthält, die durch Erweichen, Schmelzen oder Zersetzen bei Temperaturen von 150-300°C ein Kapillarsystem ausbilden können. Es ist bereits bekannt und durch die DE 42 20 274 C2 bzw. die EP 0 575 886 B1 unter Schutz gestellt, durch Zusatz derartiger Fasern bei Bauteilen aus hochfesten Betonen, insbesondere Stahlbetonbauteilen, das destruktive Abplat zen unter Brandbeanspruchung zu verhindern. Dabei weist das ge nannte Kapillarsystem im wesentlichen lineare Kapillare mit ei nem Durchmesser zwischen 10 und 100 µm und einer Länge zwischen 5 und 35 mm aus.It may also be useful if the concrete is an addition of Contains plastic fibers by softening, melting or Decompose a capillary system at temperatures of 150-300 ° C can train. It is already known and through that DE 42 20 274 C2 and EP 0 575 886 B1 are protected, by adding such fibers to components made of high-strength concrete, especially reinforced concrete components, the destructive flattening to prevent zen under fire. The ge called capillary system essentially linear capillary with egg Nem diameter between 10 and 100 microns and a length between 5 and 35 mm.
Eine erfindungsgemäße Stütze kann eine sich über ein oder mehre re Geschosshöhen erstreckende Länge aufweisen. Es ist dann zweckmäßig, wenn jeweils eine in Höhe eines Geschosses eingear beitete, gegebenenfalls mit einem Füllmaterial ausgefüllte Ta sche vorgesehen wird.A support according to the invention can be one or more re storey heights extending length. It is then It is useful if each one is at the level of a storey prepared Ta, possibly filled with a filling material cal is provided.
Die erfindungsgemäßen Stützen werden vorzugsweise als Fertig teilelemente liegend betoniert und verdichtet. Grundsätzlich ist aber auch eine Herstellung als Ortbetonstütze möglich.The supports according to the invention are preferably finished partial elements concreted and compacted horizontally. Basically is but also production as in-situ concrete supports is possible.
Für eine erfindungsgemäße Stütze gilt, dass der hochfeste Beton sowohl bei der Traglast als auch im Brandfall zusammen mit dem hochfesten Stahl die Lasten bzw. Beanspruchung aus Brand abträgt bzw. übersteht. Die Erfindung erfasst auch solche Stützen, die keine Anschlussbewehrung besitzen, sondern nur mit einem Dollen in ihrer Lage fixiert werden.For a prop according to the invention, the high-strength concrete applies both with the load capacity and in the event of fire together with the high-strength steel that withstands loads or stresses from fire or survives. The invention also covers such supports that have no connection reinforcement, but only with a oarlock be fixed in their position.
