Description

Die Erfindung betrifft ein Gebäude, ein Bauteil und eine Verwendung eines Bauteils gemäss Oberbegriff der unabhängigen Ansprüche. Durch die spezifischen Eigenschaften des Bauteils wird die Erdbebenbeanspruchung von Gebäuden reduziert.The invention relates to a building, a component and a use of a component according to the preamble of the independent claims. The specific properties of the component reduce the earthquake load on buildings.

Nach dem heutigen Stand der Technik erstellte Gebäude, insbesondere Gebäude aus Mauerwerk, sind nur bedingt in der Lage, einer Erdbebenbeanspruchung standzuhalten. Eine bekannte Art, Bauwerke erdbebensicher auszuführen, besteht darin, das Gebäude flexibel auf dem Untergrund zu lagern. Diese bekannte Konstruktionsweise bedingt eine aufwändige statische Struktur des Gebäudes und wird daher lediglich in Sonderfällen in seismisch gefährdeten Gebieten angewandt. Neue Bemessungsnormen tragen dem Umstand Rechnung, dass die Erdbebenbeanspruchung bisher unterschätzt wurde. Insbesondere Gebäude aus Mauerwerk sind aus diesem Grund in der heute üblichen Art oft nicht mehr normenkonform ausführbar.Buildings constructed according to the state of the art, in particular masonry buildings, are only partially able to withstand earthquake stress. One known way of constructing structures earthquake-proof is to flexibly store the building on the ground. This known construction requires a complex structural structure of the building and is therefore only used in special cases in seismically vulnerable areas. New design standards take into account the fact that the earthquake load has been underestimated so far. In particular, buildings made of masonry are often no longer compliant with the standard in the usual way.

Es stellt sich daher die Aufgabe, ein Gebäude bzw. ein Bauteil bereitzustellen, welche eine einfachere Lösung für eine die Erdbebenbeanspruchung reduzierende Lagerung erlauben.It is therefore the object to provide a building or a component, which allow a simpler solution for reducing the earthquake stress storage.

Diese Aufgabe wird von den unabhängigen Ansprüchen gelöst.This object is solved by the independent claims.

Beim anspruchsgemässen Gebäude sind die anspruchsgemässen Bauteile also zwischen der Kellerwand und der Kellerdecke angeordnet und bilden eine linienförmige Lagerung der Decke. Der statisch tragende Teil des Bauteils besteht aus mehreren starren Lamellen und weist zwischen den starren Lamellen angeordnete elastische Körper auf. Ein solches Bauteil ist in der Lage, durch Deformation der elastischen Körper seitliche Deformationen aufzunehmen, so dass die Kellerdecke und die darauf ruhenden Teile des Gebäudes horizontal auslenkbar sind. Durch die Anordnung des Bauteils unter der Kellerdecke wirkt diese als aussteifende Scheibe. Dadurch treten keine unterschiedlichen lokalen Verschiebungen auf der Kellerdecke auf und das Gebäude verhält sich bei Erdbebenbeanspruchung ähnlich wie ein Einmassenschwinger.In the case of the building according to the claims, the components which are required are thus arranged between the basement wall and the basement ceiling and form a line-shaped mounting of the ceiling. The static-carrying part of the component consists of a plurality of rigid slats and has between the rigid slats arranged elastic body. Such a component is able to absorb by deformation of the elastic body lateral deformations, so that the basement ceiling and resting on it parts of the building are horizontally deflectable. The arrangement of the component under the basement ceiling acts as a stiffening disc. As a result, no different local shifts occur on the basement ceiling and the building behaves in earthquake stress similar to a one-shot oscillator.

Vorzugsweise ist die Kellerdecke eine Stahlbetondecke, auf welcher die über der Kellerdecke angeordneten Wände des Gebäudes ruhen. Dies erlaubt es insbesondere, die über der Kellerdecke angeordneten Wände , insbesondere als aus Backsteinen oder anderen Mauersteinen aufgebautem Mauerwerk, auszugestalten.Preferably, the basement ceiling is a reinforced concrete ceiling, on which rest over the basement ceiling walls of the building. This makes it possible, in particular, to design the walls arranged above the basement ceiling, in particular as masonry constructed from bricks or other bricks.

Beim anspruchsgemässen Bauteil greifen die elastischen Körper in, vorzugsweise makroskopische, Vertiefungen der Lamellen ein. Dadurch werden die erforderlichen Auslenkungen unter Erzeugung der erforderlichen Rückstellkräfte ermöglicht.When claimed component, the elastic body engage in, preferably macroscopic, depressions of the slats. This allows the necessary deflections to generate the required restoring forces.

Vorzugsweise sind die elastischen Körper in den Vertiefungen der starren Lamellen eingekapselt, so dass sie sich ähnlich einer newtonschen Flüssigkeit verhalten können.Preferably, the elastic bodies are encapsulated in the depressions of the rigid fins so that they can behave like a Newtonian fluid.

Die starren Lamellen bestehen vorzugsweise aus einem Beton, insbesondere Feinbeton, der bewehrt sein kann.The rigid slats are preferably made of a concrete, in particular fine concrete, which may be reinforced.

Die Konstruktion des Bauteils erlaubt die Aufnahme von horizontalen Verschiebungen, wie sie bei Erdbeben auftreten. Durch die Dämpfungseigenschaften des Bauteils wird die dynamische Beanspruchung auf das Gebäude massgeblich reduziert.The construction of the component allows the recording of horizontal displacements, as they occur in earthquakes. The damping properties of the component significantly reduce the dynamic load on the building.

Die Breite des Elementes ist vorzugsweise auf die übliche Kellerwandbreite abgestimmt und beträgt üblicherweise 20 cm.The width of the element is preferably matched to the usual basement wall width and is usually 20 cm.

Im vertikalen Aufbau besteht das Bauteil in einer bevorzugten Ausführung aus einer Sandwichkonstruktion, wodurch die horizontale Auslenkung ermöglicht wird. Die zu ermöglichenden Auslenkungen betragen vorzugsweise 4 - 6 cm.In the vertical structure, the component in a preferred embodiment of a sandwich construction, whereby the horizontal deflection is made possible. The deflections to be enabled are preferably 4 - 6 cm.

Die elastischen Körper bestehen vorzugsweise aus Elastomer, da dieses Material gute elastische Eigenschaften und gute Dämpfungseigenschaften besitzt und hohen Druckbelastungen standhält.The elastic bodies are preferably made of elastomer, since this material has good elastic properties and good damping properties and withstands high pressure loads.

Durch die entsprechende Härte des elastischen Körpers und dessen geometrischer Ausbildung wird die Rückstellkraft bei Auslenkung erzeugt. Vorzugsweise weisen die elastischen Körper einen kreisförmigen Grundriss auf mit einem ellipsen- oder linsenförmigen vertikalen Querschnitt. Es können aber auch ein oder mehrere Kreisringförmige Körper mit toroidaler Form eingesetzt werden.Due to the corresponding hardness of the elastic body and its geometric configuration, the restoring force is generated at deflection. Preferably, the elastic bodies have a circular outline with an elliptical or lenticular vertical cross-section. However, it is also possible to use one or more annular bodies with a toroidal shape.

Um Reibungskräfte bei horizontalen Auslenkungen zu vermeiden, sind die Bauteile, insbesondere die elastischen Körper, vorzugsweise so ausgebildet, dass sich die starren Lamellen nicht berühren. Auf diese Weise werden die Vertikalkräfte lediglich über die elastischen Körper übertragen und durch diese die Dämpfung und Rückstellkraft erzeugt.In order to avoid frictional forces in horizontal deflections, the components, in particular the elastic body, are preferably formed so that the rigid blades do not touch. In this way, the vertical forces are transmitted only through the elastic body and generated by this the damping and restoring force.

Die Ausbildung des statisch wirksamen Teils des Bauelementes ist vorzugsweise quadratisch.The formation of the statically effective part of the component is preferably square.

Angrenzend an den statisch wirksamen Teil des Bauteils, der einen ersten Abschnitt bildet, können statisch nicht wirksame Ergänzungsteile bzw. zweite Abschnitte angeordnet werden, sodass das Bauelement einen länglichen Grundriss aufweist. Um für verschiedene Laststufen den identischen statisch wirksamen Teil verwenden zu können, wird der statisch nicht wirksame Ergänzungsteil in der entsprechenden Länge ausgebildet. Die theoretisch linienförmige Lagerung der Kellerdecke wird dadurch punktförmig. Der Abstand der statisch wirksamen Teile des Elementes wird vorzugsweise nicht grösser gewählt, als die Kellerdecke ohne spezielle Aussteifung zulässt. Dieser Abstand der Punktlager bedingt damit keine speziellen Massnahmen für die Randausbildung der Kellerdecke und kann allenfalls in einer geeigneten Ausbildung der Bewehrung des Deckenrandes bestehen.Adjacent to the statically effective part of the component, which forms a first section, static non-effective supplementary parts or second sections can be arranged so that the component has an elongated plan. In order to use the identical statically effective part for different load levels, the statically not effective supplementary part is formed in the appropriate length. The theoretical linear storage of the basement ceiling is punctiform. The distance of the statically effective parts of the element is preferably not chosen larger than the basement ceiling without special stiffening permits. This distance of the point bearing thus requires no special measures for the edge formation of the basement ceiling and can at best consist of a suitable design of the reinforcement of the ceiling edge.

Die Oberflächen des tragenden Teils des Bauelementes sind so ausgebildet, dass die aus dynamischer Erdbebenbeanspruchung entstehenden Horizontalkräfte übertragen werden können. Dies kann vorzugsweise durch eine entsprechende geometrische Ausbildung erfolgen oder alternativ durch die Möglichkeit eines Bewehrungsanschlusses.The surfaces of the supporting part of the component are designed so that the horizontal forces arising from dynamic earthquake stress can be transmitted. This can preferably be done by a corresponding geometric design or alternatively by the possibility of a rebar connection.

Weitere bevorzugte Ausführungen und Anwendungen werden in den abhängigen Ansprüchen und der nun folgenden Beschreibung anhand der Figuren genannt. Dabei zeigen:

  • Fig. 1 einen Vertikalschnitt durch ein Gebäude mit einer möglichen Anordnung des erfindungsgemässen Bauteils,
  • Fig. 2 einen Vertikalschnitt durch eine Ausführung des erfindungsgemässen Bauteils und
  • Fig. 3 eine dreidimensionale Ansicht einer Anordnung mit einem Bauteil.
Further preferred embodiments and applications are specified in the dependent claims and the description which follows, with reference to the figures. Showing:
  • 1 shows a vertical section through a building with a possible arrangement of the inventive component,
  • Fig. 2 is a vertical section through an embodiment of the inventive component and
  • Fig. 3 is a three-dimensional view of an arrangement with a component.

Die bevorzugte Anordnung des Bauteils ist in Fig. 1 und Fig. 3 dargestellt. Das Bauteil 1 ist auf der Kellerwand 8 und unter der Kellerdecke 9 angeordnet.The preferred arrangement of the component is shown in FIGS. 1 and 3. The component 1 is arranged on the basement wall 8 and under the basement ceiling 9.

Eine erste bevorzugte Ausführung des erfindungsgemässen Bauteils 1 ist in Fig. 2 dargestellt. Das Bauteil weist eine Sandwichstruktur auf mit mehreren starren Lamellen 2 und einzelnen elastischen Körpern 3. Die Bezeichnung "starre Lamellen" drückt dabei aus, dass die Lamellen starrer als die elastischen Körper sind, während die Bezeichnung "elastische Körper" ausdrückt, dass die Körper 3 stärker elastisch deformierbar sind als dieLamellen.A first preferred embodiment of the inventive component 1 is shown in Fig. 2. The term "rigid lamellae" expresses that the lamellae are more rigid than the elastic body, while the term "elastic body" expresses that the body 3 are more elastically deformable than the lamellae.

Vorzugsweise weisen die elastischen Körper 3 Elastomer auf oder bestehen vollständig aus Elastomer.Preferably, the elastic bodies 3 comprise elastomer or consist entirely of elastomer.

In den einander gegenüber liegenden Oberflächen der Lamellen 2 sind Vertiefungen 2a angeordnet, in welche die elastischen Körper 3 eingreifen.In the opposite surfaces of the slats 2 wells 2 a are arranged, in which engage the elastic body 3.

In der gezeigten Ausführung sind pro Lamelle 2 vier elastische Körper 3 vorgesehen. Die Anzahl der elastischen Körper kann auch geringer oder allenfalls grösser gewählt werden. Die elastischen Körper 3 sind vorzugsweise so gross ausgebildet, dass sich die Oberflächen 4 der starren Lamellen 2 nicht berühren und Zwischenräume 5 entstehen, welche verhindern, dass aus Vertikallasten Reibungskräfte zwischen den starren Lamellen 2 entstehen. In einer bevorzugten Ausführung kann in den Zwischenräumen 5 expandiertes Polystyrol (EPS) angeordnet sein, das bei Horizontalverschiebungen lediglich vernachlässigbare Kräfte erzeugt.In the embodiment shown, two elastic bodies 3 are provided per blade 2. The number of elastic Body can also be chosen smaller or possibly larger. The elastic bodies 3 are preferably made so large that the surfaces 4 of the rigid slats 2 do not touch and gaps 5 are formed which prevent frictional forces between the rigid slats 2 from vertical loads. In a preferred embodiment, expanded polystyrene (EPS) can be arranged in the intermediate spaces 5, which only generates negligible forces during horizontal displacements.

In den Zwischenräumen 5 können auch feurerbeständige bzw. schwer entflammbare Materialien, wie beispielsweise Steinwolle, angeordnet sein. Diese Materialien sollten weicher sein als die Lamellen 2 und die Körper 3, damit sie keine wesentliche statische Funktion haben und die relative Beweglichkeit der Lamellen 2 gewährleistet bleibt.In the interstices 5 also fire resistant or flame retardant materials, such as rock wool, can be arranged. These materials should be softer than the slats 2 and the bodies 3, so that they have no significant static function and the relative mobility of the slats 2 is ensured.

Die Elementoberflächen 6 und 7 sind so ausgebildet, dass die aus dynamischer Erdbebenbeanspruchung entstehenden Horizontalkräfte in die Kellerwand 8 und in die Kellerdecke 9 übertragen werden können. Hierzu sind die Elementoberflächen 6, 7 mit Anschlussmitteln zur Übertragung von horizontalen Scherkräften versehen. Hierbei kann es sich z.B. um Erhöhungen oder Vertiefungen 6a, 7a, aber beispielsweise auch um entsprechende Stege oder Armierungsanschlüsse handeln.The element surfaces 6 and 7 are designed so that the horizontal forces arising from dynamic earthquake stress can be transmitted into the basement wall 8 and into the basement ceiling 9. For this purpose, the element surfaces 6, 7 are provided with connecting means for transmitting horizontal shear forces. This may be e.g. to elevations or depressions 6a, 7a, but for example, to act on corresponding webs or reinforcing connections.

Die Kellerdecke 9 ist vorzugsweise als über den ganzen Gehäusegrundriss zusammenhängende Stahlbetondecke ausgestaltet, auf welcher die über der Kellerdecke angeordneten Wände 14 ruhen.The basement ceiling 9 is preferably configured as a reinforced concrete floor connected over the entire housing ground plan, on which rest the walls 14 arranged above the basement ceiling.

Eine bevorzugte Gestaltung des Bauteils 1 zeigt Fig. 3. Die starren Lamellen 2 und die elastischen Körper 3 bilden einen ersten Abschnitt 10 des Bauteils. Seitlich an den ersten Abschnitt 10, d.h. stirnseitig an die Lamellen 2, schliesst sich mindestens ein zweiter Abschnitt 11 an - im Beispiel nach Fig. 3 sind beidseits des ersten Abschnitts 10 derartige zweite Abschnitte 11 angeordnet. Der erste Abschnitt 10 hat dabei für Druckkräfte senkrecht zu den Lamellen eine wesentlich höhere Drucksteifigkeit als die beiden zweiten Abschnitte 11. Unter Drucksteifigkeit ist dabei die Kraft zu verstehen, die notwendig ist, um einen Körper um eine vorgegebene (kleine) Höhe zu komprimieren. Die zweiten Abschnitte bilden angrenzend an den ersten Teil u.a. einen Puffer, der die unter Erdbeben auftretenden Auslenkungen ermöglicht.A preferred design of the component 1 is shown in FIG. 3. The rigid blades 2 and the elastic bodies 3 form a first portion 10 of the component. At least one second section 11 adjoins the first section 10, ie the front side of the slats 2, in the side of the first section 10-in the example according to FIG. 3, such second sections 11 are on both sides of the first section 10 arranged. For pressure forces perpendicular to the lamellae, the first portion 10 has a much higher compressive stiffness than the two second portions 11. Stiffness of pressure is understood here as the force which is necessary in order to compress a body by a predetermined (small) height. The second sections form adjacent to the first part, inter alia, a buffer that allows the occurring under earthquake deflections.

Indem der erste Abschnitt 10 eine wesentlich höhere Drucksteifigkeit als die beiden zweiten Abschnitte 11 besitzt, nimmt der erste Abschnitt 10 den weitgehend grössten Teil der Kräfte auf, während die Abschnitte 11 statisch nicht wirksam sind. Die Abschnitte 11 definieren lediglich die Abstände der ersten Abschnitte 10 benachbarter Bauteile 1. Durch Variation der Länge der zweiten Abschnitte 11 kann für unterschiedliche Vertikallasten die statische Beanspruchung des statisch wirksamen Abschnitts 10 beeinflusst werden. Die Kellerdecke 8 ist also im Wesentlichen nur auf den ersten Abschnitten 10 gelagert. Die Abstände der ersten Abschnitte 10 bzw. die Länge der zweiten Abschnitte 11 sind so zu bemessen, dass die Kellerdecke die Kraft auf die ersten Abschnitte 10 abzuleiten vermag.By the first portion 10 has a much higher compressive stiffness than the two second sections 11, the first portion 10 takes up the greater part of the forces, while the sections 11 are not statically effective. The sections 11 only define the distances of the first sections 10 of adjacent components 1. By varying the length of the second sections 11, the static load of the statically effective section 10 can be influenced for different vertical loads. The basement ceiling 8 is thus stored substantially only on the first sections 10. The distances of the first sections 10 and the length of the second sections 11 are to be dimensioned so that the basement ceiling is able to derive the force on the first sections 10.

Die zweiten Abschnitte 11 sind vorzugsweise aus EPS gefertigt und gegenbenfalls mit einer Schutzbeschichtung versehen. Sie können auch bauseitig auf die jeweils richtige Länge abgelängt werden und können hierzu mit entsprechenden Markierungen 16 versehen sein.The second sections 11 are preferably made of EPS and, in contrast, provided with a protective coating. You can also be cut to size on the right length and can be provided with appropriate markings 16 for this purpose.

Denkbar ist jedoch auch, dass das Bauteil nur als Abschnitt 10 ohne die Abschnitte 11 (resp. mit für die Pufferfunktion notwendigen kurzen Abschnitten 11) an die Baustelle geliefert wird. In diesem Fall geschieht die richtige Abstandssetzung bauseits, z.B. durch Füllen der Zwischenräume zwischen den Bauteilen. Dabei ist jedoch darauf zu achten, dass die freie Auslenkbarkeit der Kellerdecke gewährleistet bleibt. Wird z.B. zwischen den Bauteilen Beton eingefüllt, so ist darauf zu achten, dass der Beton nicht bis zur Decke geht und ein (z.B. mit EPS gefüllter) Abstand zwischen Wandbeton und Decke bestehen bleibt.However, it is also conceivable for the component to be delivered to the construction site only as a section 10 without the sections 11 (or with short sections 11 necessary for the buffer function). In this case, the correct spacing is done by the customer, eg by filling the gaps between the components. However, it must be ensured that the free deflection of the basement ceiling is guaranteed. For example, between the It is important to ensure that the concrete does not rise to the ceiling and that a gap (eg filled with EPS) remains between the wall concrete and the ceiling.

Um Anforderungen an den Brandschutz zu genügen, kann auf der Elementaussenseite 12 und Elementinnenseite 13 eine Brandschutzverkleidung aufgebracht werden, oder der Zwischenraum 5 kann, wie erwähnt, mit einer feuerbeständigen weichen Folie gebildet werden.To meet requirements for fire protection, a fire protection panel can be applied to the element outer side 12 and element inner side 13, or the gap 5, as mentioned, are formed with a fire-resistant soft film.
