Description
Die vorliegende Erfindung betrifft einen Befestigungsanker zum Befestigen einer Fassade an einem Gebäude.The present invention relates to a fixing anchor for fixing a facade to a building.
Befestigungsanker sind bekannt und werden beispielsweise über Schraubenbolzen an einer Betondecke oder einem Betonboden befestigt, so daß an einem Abschnitt des Befestigungsankers die Gebäudefassade bzw. deren Fassadenelemente oder Paneele oder dergleichen befestigt werden können. Ein derartiger Befestigungsariker ist dazu ausgestaltet, Lasten, wie beispielsweise Eigenlast der Fassade, Wind, Schnee usw., aufzunehmen und in das Bauwerk einzuleiten. Übliche Windlastbefestigungen bestehen im wesentlichen aus einer flachen Platte. Es gibt darüber hinaus verstärkte Ausführungen, sogenannte Bomb-Last-Befestigungen, die kurzzeitig sehr hohe Lasten in das Bauwerk einleiten können, wie sie beispielsweise bei einem Anprall oder einer Explosion entstehen.Fastening anchors are known and are fastened, for example via bolts on a concrete floor or a concrete floor, so that the building facade or its facade elements or panels or the like can be attached to a portion of the fastening anchor. Such Befestigungsariker is designed to take loads such as dead load on the facade, wind, snow, etc., and initiate into the building. Usual wind load attachments consist essentially of a flat plate. There are also reinforced versions, so-called bomb-load fasteners, which can temporarily induce very high loads in the structure, such as occur in an impact or an explosion.

Es besteht somit ein Bedarf für einen verbesserten Befestigungsanker, der Schäden an Gebäuden und/oder Fassaden bzw. Paneelen vermeiden oder zumindest verringern kann bzw. eine Belastung bei Anprall oder Explosion oder dergleichen minimieren kann.Thus, there is a need for an improved mounting anchor that can avoid or at least reduce damage to buildings and / or facades or panels, or minimize stress in impact or explosion or the like.
Die Aufgabe der Erfindung besteht somit in der Schaffung eines Befestigungsankers zum Verhindern bzw. Minimieren von Schäden an Gebäudekomponenten und/oder Fassaden.The object of the invention is thus to provide a fastening anchor for preventing or minimizing damage to building components and / or facades.
Diese Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen definiert.This object is solved by the subject matter of the independent claim. Advantageous developments are defined in the dependent claims.
Erfindungsgemäß hat ein Befestigungsanker für Fassaden, Verkleidungen, Paneele etc. zumindest einen Verformungsabschnitt, der bei Zug- und/oder Druckbelastung eine vorgegebene plastische Verformung erfährt. Indem der Befestigungsanker nicht- starr ausgebildet ist, sondern einen Verformungsabschnitt aufweist, der eine vorgegebene plastische Verformung bei Belastung vollzieht, wird ein Großteil der Belastüngsenergie durch die plastische Verformung des Befestigungsankers absorbiert, um die Belastung der Gebäudekomponenten zu verringern.According to the invention, a fixing anchor for facades, cladding, panels, etc., has at least one deformation section which experiences a predetermined plastic deformation under tensile and / or compressive loading. By making the attachment anchor non-rigid but having a deformation section that performs a predetermined plastic deformation under load, much of the stress energy is absorbed by the plastic deformation of the attachment anchor to reduce stress on the building components.

Krafteinleitung eine vorgegebene oder vorgebbare plastische Verformung des Verformungsabschnitts auftritt. Somit wird bei Belastung bzw. Krafteinleitung in den Befestigungsanker eine vorgegebene bzw. vorgebbare bzw. bestimmbare Energie absorbiert, indem der Verformungsabschnitt um einen vorgegebenen bzw. vorgebbaren Betrag verformt wird.The deformation section is designed or configured or configurable in such a way that a predetermined or specifiable plastic deformation of the deformation section occurs in the case of a specific or determinable or predetermined or predefinable load or force introduction. Thus, a predetermined or specifiable or determinable energy is absorbed under load or force introduction into the fastening anchor by deforming the deformation section by a predetermined or specifiable amount.
Der Befestigungsanker ist mittels einer Grundplatte mit dem Gebäude, insbesondere starr, verbunden. Die Fassade wird an einer Fassadenbefestigung an dem Befestigungsanker befestigt. Der Verformungsabschnitt ist in an einem Gebäude montiertem Zustand auf der dem Gebäude abgewandten oder zugewandten Seite der Grundplatte, d.h. auf der Wetterseite oder raumseitig, angeordnet.

Insbesondere kann der mikroskopische Elastizitätsmodul E und/oder der mikroskopische Schermodul G des Verformungsabschnitts größer sein, als der makroskopische Elastizitätsmodul Em und/oder der makroskopische Schermodul Gm.The deformation section has a macroscopic elastic modulus E m and / or a macroscopic shear modulus G m , which is smaller than the macroscopic elasticity and / or shear modulus of the regions of the fastening anchor or the base plate or the facade fastening adjacent to the deformation section. In particular, the microscopic elastic modulus E and / or the microscopic shear modulus G of the deformation section may be greater than the macroscopic elastic modulus Em and / or the macroscopic shear modulus Gm.
Insbesondere kann der mikroskopische Elastizitätsmodul E und/oder der mikroskopische Schermodul G des Verformungsabschnitts gleich dem mikroskopische Elastizitäts- und/oder Schermodul der an den Verformungsabschnitt angrenzenden Bereiche des Befestigungsankers bzw. der Grundplatte bzw. der Fassadenbefestigung sein.In particular, the microscopic elastic modulus E and / or the microscopic shear modulus G of the deformation section can be equal to the microscopic elasticity and / or shear modulus of the regions of the fastening anchor or the base plate or the facade fastening adjacent to the deformation section.
Unter dem makroskopischen Elastizitätsmodul Em des Verformungsabschnitts bzw. der Grundplatte wird im folgenden eine Materialkonstante verstanden, welche innerhalb der Elastizitätsgrenze die Proportionalität zwischen der an den Verrformungsabschnitt bzw. der Grundplatte angelegten Spannung σ=F/A und der daraus resultierenden relativen Dehnung bzw. Stauchung ε=Δl/l quantifiziert. Dabei entspricht F der angelegten Kraft, A der Querschnittsfläche, Δl der Längenänderung und I der Länge. Für kleine Spannungen, d.h. unterhalb der Elastizitätsgrenze gilt ε=1/Em×σ. Die Größe wird deshalb als makroskopisches Elastizitätsmodul Em bezeichnet, weil auch Materialentfernungen aus dem Verformungsabschnitt bzw. der Grundplatte zur Berechnung zur Bestimmung des makroskopischen Elastizitätsmodul Em berücksichtigt werden.The macroscopic elastic modulus E m of the deformation section or the base plate is understood below to mean a material constant which, within the elastic limit, determines the proportionality between the stress σ = F / A applied to the deformation section or the base plate and the resulting relative expansion or compression ε = Δl / l quantified. In this case, F corresponds to the applied force, A the cross-sectional area, Δl the change in length and I the length. For small stresses, ie below the elastic limit, ε = 1 / E m × σ. The size is therefore referred to as the macroscopic modulus of elasticity E m , because material distances from the deformation section or the base plate are also taken into account for the calculation for determining the macroscopic elastic modulus E m .
Im Gegensatz dazu wird unter dem mikroskopischen Elastizitätsmodul E des Verformungsabschnitts bzw. der Grundplatte die Materialkonstante des Vollmaterials verstanden, aus welchem der Verformungsabschnitt bzw. die Grundplatte hergestellt ist.In contrast, the microscopic elastic modulus E of the deformation section or the base plate is understood to be the material constant of the solid material from which the deformation section or the base plate is made.
Analog wird zwischen dem makroskopischen Schermodul Gm und dem mikroskopischen Schermodul G unterschieden, wobei für kleine Spannungen, d.h. unterhalb der Elastizitätsgrenze gilt α=1/Gm×σ mit α als Winkel der Scherung.Analogously, a distinction is made between the macroscopic shear modulus G m and the microscopic shear modulus G, where for small stresses, ie below the elastic limit, α = 1 / G m × σ with α as the angle of shear.
Wenn bei einer vorzugsweisen einstückigen Ausbildung des Befestigungsankers Materialausnehmungen bzw. Materialschwächungen (z.B. durch Bohrungen, Schlitze, Sicken, etc.) im Bereich des Verformungsabschnitts ausgebildet sind, kann der mikroskopische Elastizitäts- und/oder Schermodul (E und/oder G) innerhalb des Befestigungsankers konstant sein und gleichzeitig der makroskopische Elastizitäts- und/oder Schermodul (Em und/oder Gm) innerhalb der Befestigungsankers variieren.If material recesses or material weakenings (eg, through bores, slots, beads, etc.) are formed in the region of the deformation section in a preferred one-piece design of the fastening anchor, the microscopic elasticity and / or shear modulus (E and / or G) can be within the fastening anchor be constant and at the same time vary the macroscopic elasticity and / or shear modulus (E m and / or G m ) within the attachment anchor.
D.h. vorzugsweise ist der makroskopische Elastizitäts- und/oder Schermodul (Em und/oder Gm) des Verformungsabschnitt kleiner als der makroskopische Elastizitäts- und/oder Schermodul (Em und/oder Gm) der Grundplatte und kleiner als der mikroskopische Elastizitäts- und/oder Schermodul (E und/oder G) des Verformungsabschnitts.That is, preferably the macroscopic modulus of elasticity and / or shear (E m and / or G m ) of the deformation section is smaller than the macroscopic modulus of elasticity and / or shear (E m and / or G m ) of the base plate and smaller than the microscopic elasticity modulus. and / or shear modulus (E and / or G) of the deformation section.
Weiter kann der Befestigungsanker derart ausgebildet sein, daß der mikroskopische Elastizitäts- und/oder Schermodul (E und/oder G) des Verformungsabschnitts kleiner ist als der mikroskopische. Elastizitäts- und/oder Schermodul der Grundplatte bzw. des restlichen Befestigungsankers. Diese Ausbildung kann durch Änderung der Zusammensetzung und/oder Struktur des Materials des Verformungsabschnitts im Gegensatz zum an den Verformungsabschnitt angrenzenden Materials des Befestigungsankers erreicht werden. Zum einen kann insbesondere der Verformungsabschnitt insbesondere aus einem anderen Material bestehen und/oder die nicht zum Verformungsabschnitt gehörenden Bereiche des Befestigungsankers partiell gehärtet sein. Eine Verringerung des makroskopischen Elastizitäts- und/oder Schermoduls des Verformungsabschnitts kann insbesondere durch einen unterschiedlichen Sinterungsgrad bei der pulvermetallurgischen Herstellung des Befestigungsankers erreicht werden.Further, the fixing anchor may be formed such that the microscopic elasticity and / or shear modulus (E and / or G) of the deformation portion is smaller than the microscopic one. Elasticity and / or shear modulus of the base plate or of the remaining fastening anchor. This design can be achieved by changing the composition and / or structure of the material of the deformation section as opposed to the material of the attachment anchor adjacent to the deformation section. On the one hand, in particular, the deformation section can consist in particular of a different material and / or the areas of the attachment anchor not belonging to the deformation section can be partially hardened. A reduction of the macroscopic modulus of elasticity and / or shear of the deformation section can be achieved in particular by a different degree of sintering in the powder metallurgical production of the fastening anchor.
Der Verformungsabschnitt weist dabei Querschnittsschwächungen, Aussparungen, Vertiefungen und/oder Verformungselemente wie beispielsweise Stege, stabförmige Elemente, verformbare Schichten zwischen geschichteten Platten etc. auf.The deformation section has cross-sectional weakenings, recesses, depressions and / or deformation elements such as webs, rod-shaped elements, deformable layers between layered plates, etc.
Durch die geometrische Ausbildung und die Größe der elastischen Moduln des Verformungsabschnitts, ist der Verformungsabschnitt bei Beaufschlagung mit einer vorbestimmten Kraft bzw. Spannung vorgebbar plastisch verformbar. Insbesondere ist der Verformungsabschnitt bei Beaufschlagung mit einer vorbestimmten Kraft bzw. Spannung vorgebbar plastisch verformbar, während der den Verformungsabschnitt umgebende Bereich des Befestigungsankers bzw. die Grundplatte durch die Beaufschlagung mit der vorbestimmten Kraft bzw. Spannung lediglich elastisch verformbar ist, da die Elastizitätsgrenze des Materials nicht überschritten wird. Die plastische Verformung des Verformungsabschnitts führt zu einer Absorption der durch die Kraftbeaufschlagung in den Befestigungsanker eingebrachten Energie, wobei vorzugsweise der Verformungsabschnitt durch die plastische Verformung verfestigt wird. Vorteilhafterweise wird die Gebäudekonstruktion, insbesondere die Befestigungsstelle des Befestigungsankers, d.h. der Grundplatte, mit der Gebäudekonstruktion, um den Betrag der durch den Verformungsabschnitt absorbierten Energie entlastet und kann daherschwächer ausgeführt werden.As a result of the geometric design and the size of the elastic modules of the deformation section, the deformation section can be plastically deformed upon application of a predetermined force or tension. In particular, the deformation portion upon application of a predetermined force or voltage is predetermined plastically deformable, while the surrounding deformation portion of the fastening anchor or the base plate by the application of the predetermined force or voltage is only elastically deformable, since the elastic limit of the material is not is exceeded. The plastic deformation of the deformation section leads to absorption of the energy introduced by the application of force into the fastening anchor, wherein preferably the deformation section is solidified by the plastic deformation. Advantageously, the building construction, in particular the fastening point of the fastening anchor, ie the base plate, with the building construction, relieved by the amount of energy absorbed by the deformation section and can therefore be made weaker.
Nach der Beaufschlagung des Befestigungsankers mit der vorbestimmten Kraft bzw. Spannung kehren die elastisch verformten Bereiche des Befestigungsankers im wesentlichen zu ihrer-ursprünglichen Form zurück, während der Verformungsabschnitt in vorgebbare bzw. vorbestimmter Weise verformt bleibt.After the fastening anchor is subjected to the predetermined force or stress, the elastically deformed regions of the fastening anchor essentially return to their original shape, while the deformation section remains deformed in a predeterminable or predetermined manner.
Mit anderen Worten bewirkt der erfindungsgemäße Befestigungsanker für die Anordnung von Fassadenteilen an einem Gebäude vorteilhafterweise mittels des Verformungsabschnitts, welcher bei einer vorbestimmbaren Beaufschlagung mit einer mechanischen Spannung in einer vorbestimmbaren Weise um einem vorbestimmbaren Betrag verformt wird, eine geringere mechanische Belastung der tragenden Gebäudekonstruktion, da die in den Befestigungsanker eingeleitete Energie teilweise, insbesondere größtenteils, in Verformungsenergie zur Verformung des Verformungsabschnitts umgewandelt wird und dadurch die in die Gebäudekonstruktion eingeleitete Energie kleiner ist als die in den Befestigungsanker eingeleitete Energie.In other words, the fastening anchor according to the invention for the arrangement of facade parts on a building advantageously by means of the deformation portion, which is deformed by a predeterminable amount at a predeterminable application of a mechanical stress in a predeterminable manner, causes a lower mechanical load on the supporting building structure, as the energy introduced into the fastening anchor is partially, in particular for the most part, converted into deformation energy for deformation of the deformation section, and thereby the energy introduced into the building structure is smaller than the energy introduced into the fastening anchor.
Der Verformungsabschnitt hat eine Vielzahl von durch Aussparungen oder Vertiefungen oder Querschnittsreduktionen voneinander getrennter Stege. Somit kann der Verformungsabschnitt auf einfache und kostengünstige Weise hergestellt werden. Darüber hinaus kann ein gewünschtes Verformungsverhalten, d.h. aufgenommene bzw. absorbierte Arbeit, Verformungsweg, Verformungsrichtung etc. durch Anordnung, Anzahl, Querschnitt etc. der Stege, Aussparungen, Vertiefungen bzw. Querschnittsreduktionen erzielt werden.The deformation portion has a plurality of ridges separated by recesses or depressions or cross-sectional reductions. Thus, the deformation portion can be manufactured in a simple and inexpensive manner. In addition, a desired deformation behavior, i. absorbed or absorbed work, deformation path, deformation direction, etc. by arrangement, number, cross section, etc. of the webs, recesses, depressions or cross-sectional reductions can be achieved.
Erfindungsgemäß ist zumindest ein erster Steg konfiguriert, um sowohl bei Druckbelastung als auch bei Zugbelastung zu wirken und zumindest ein zweiter Steg, um nur bei Druck- oder nur bei Zugbelastung zu wirken, d.h. der erste Steg verformt sich sowohl bei Druck als auch Zugbelastung, während der zweite Steg nur in einer Belastungsrichtung verformt wird und in der anderen Richtung im wesentlichen keine Kraft aufnimmt.According to the invention, at least one first web is configured to be both at Compressive load as well as tensile load to act and at least a second web to act only under pressure or only with tensile load, ie the first web deforms both under pressure and tensile load, while the second web is deformed only in a loading direction and in the other direction receives essentially no force.
Vorzugsweise sind Stege und Aussparungen durch Bohrungen in dem Verformungsabschnitt gebildet, so daß die Bohrungen den Aussparungen entsprechen und die zwischen benachbarten Bohrungen verbleibenden Materialränder die Stege bilden.Preferably, webs and recesses are formed by bores in the deformation portion, so that the holes correspond to the recesses and the remaining material between adjacent holes form the webs.
Weiter bevorzugt hat der Befestigungsanker zumindest ein Zwischenglied, das vorzugsweise als im wesentlichen zu den Stegen senkrecht angeordneter Balkenabschnitt ausgebildet ist und eine Verbindung der Stege mit einer Grundplatte bildet und wobei zumindest ein Steg fix mit dem Zwischenglied verbunden ist und zumindest ein anderer Steg gegenüber dem Zwischenglied in einer Richtung verschiebbar angeordnet ist sowie in der entgegengesetzten Richtung an ein Anschlagelement anstößt, wobei das Anschlagelement vorzugsweise an dem Zwischenglied angeordnet ist. Dabei ist vorzugsweise ein Paar Zwischenglieder als balkenförmige Bauteile auf entgegengesetzten Seiten der Stege angeordnet.More preferably, the attachment anchor has at least one intermediate member, which is preferably designed as substantially perpendicular to the webs beam portion and forms a connection of the webs with a base plate and wherein at least one web is fixedly connected to the intermediate member and at least one other web relative to the intermediate member is slidably disposed in one direction and abuts in the opposite direction to a stop element, wherein the stop element is preferably arranged on the intermediate member. In this case, a pair of intermediate links is preferably arranged as bar-shaped components on opposite sides of the webs.
Vorzugsweise weist das Anschlagelement eine Schräge auf, auf die ein verschiebbarer Steg bei der Verformung aufläuft. Auf diese Weise steigt eine in den verschiebbaren Steg eingeleitete Kraft mit zunehmender Verformung an, so daß der Steg eine kontinuierlich ansteigende Belastung aufnimmt.Preferably, the stop element has a slope, which runs onto a displaceable web during the deformation. In this way, an introduced into the displaceable web force increases with increasing deformation, so that the web receives a continuously increasing load.
Vorzugsweise ist eine Grundplatte des Befestigungsankers über stabförmige Elemente bzw. Stifte bzw. Bolzen mit zumindest einer, vorzugsweise einem Paar Ankerplatte(n) verbunden, wobei die stabförmigen Elemente plastisch verformbar sind. Auf diese Weise bilden die stabförmigen Elemente einen Verformungsabschnitt, der mit Stegen kombiniert werden kann, um zwei Verformungsabschnitte vorzusehen. Die stabförmigen Elemente können jedoch auch ohne Vorsehen von Stegen angeordnet sein, wenn nur ein Verformungsabschnitt gebildet werden soll. In anderen Worten kann ein gewünschtes Verformungsverhalten des Verformungsabschnitts durch Anzahl und Art von Verformungselementen (Stege und/oder stabförmige Elemente) und deren Konfiguration erzielt werden.Preferably, a base plate of the fastening anchor via rod-shaped elements or pins or bolts with at least one, preferably a pair of anchor plate (s) is connected, wherein the rod-shaped elements are plastically deformable. In this way, the rod-shaped elements form a deformation section that can be combined with webs to provide two deformation sections. However, the rod-shaped elements can also be arranged without the provision of webs, if only a deformation section is to be formed. In other words, a desired deformation behavior of the deformation section can be achieved by the number and type of deformation elements (webs and / or rod-shaped elements) and their configuration.
Weiter bevorzugt ist eine Zwischenschicht in einem Zwischenraum zwischen Grundplatte und Ankerplatte(n) angeordnet, die Metall und/oder Kunststoff aufweist. Diese Zwischenschicht kann weitere Verformungskräfte aufnehmen, wenn sich aufgrund der Krafteinleitung in die Grundplatte diese gegenüber der bzw. den Ankerplatte(n) verschiebt.More preferably, an intermediate layer in an intermediate space between the base plate and anchor plate (s) is arranged, which has metal and / or plastic. This intermediate layer can absorb further deformation forces, if, due to the introduction of force into the base plate, this shifts relative to the anchor plate (s).

Obwohl es hier nicht gezeigt ist, kann die Grundplatte 100 einfache Bohrungen oder vorzugsweise Langlöcher aufweisen, die vorzugsweise gezahnt sind, um gezahnte Beilagscheiben in diesen Langlöchern anzuordnen und die Beilagscheiben über Schrauben, Bolzen oder dergleichen mit einer Betonkomponente des Gebäudes zu verbinden. Dabei ist eine Durchgangsbohrung der Beilagscheibe vorzugsweise exzentrisch angeordnet, um durch Verdrehen der Beilagscheibe um 90 Grad oder 180 Grad eine weitere Feinjustierung zu erhalten. Bezüglich dieser Befestigung der Grundplatte 110 wird auf die Patentschrift
Die Grundplatte 110 ist nicht über einen steifen bzw. starren Abschnitt bzw. Körper mit der Fassadenbefestigung 130 verbunden, sondern über einen Verformungsabschnitt 120, der bei Belastung in Zug- und/oder Druckrichtung eine vorgegebene plastische Verformung erfährt, um Energie zu absorbieren.The
In anderen Worten ist der Befestigungsanker nur bis zu einer Belastung in Höhe der Windlast starr bzw. elastisch verformbar und verformt sich bei höheren Belastungswerten plastisch bzw. permanent. Je nach Anwendungsfall kann der Verformungsabschnitt jedoch auch auf andere Werte als die hier angegebene Windlast eingestellt werden. Des weiteren können die Werte für Druck- und Zugbelastung unterschiedlich sein, wenn in der einen Richtung alle (nachfolgend erläuterten) Verformungselemente und in der anderen Richtung nur vorgegebene Verformungselemente wirken, d.h. indem beispielsweise einseitig und zweiseitig wirkende Stege angeordnet sind.In other words, the fastening anchor is rigid or elastically deformable only up to a load at the level of the wind load and deforms plastically or permanently at higher load values. Depending on the application, however, the deformation section can also be set to other values than the wind load specified here. Furthermore, the values for compressive and tensile loading may be different if in one direction all the deformation elements (explained below) and in the other direction only predetermined deformation elements act, i. by, for example, one-sided and two-sided webs are arranged.
Der Verformungsabschnitt kann beispielsweise, wie in
Die Verformungsarbeit zum Verbiegen des zumindest einen Stegs 122 absorbiert die Energie bei der Belastung, des Befestigungsankers 100. Somit können Belastungen des Gebäudes und/oder der Fassade minimiert werden. Eine Beispielrechnung hat gezeigt, daß die Querkräfte beispielsweise in den Pfosten im Bereich des Befestigungsankers 100 von 330kN im Falle eines Befestigungsankers nach dem Stand der Technik auf ca. 200kN im Falle eines erfindungsgemäßen Befestigungsankers minimiert werden können.The deformation work for bending the at least one
Die Minimierung der Auflagerlast kann somit Schäden an dem Gebäude verhindern bzw. minimieren. Darüber hinaus können kleinere Befestigungen, Dübel, sogenannte Halfenschienen, Stahleinbauteile usw. verwendet werden, um Kosten und Arbeitszeit bei der Befestigung zu sparen.Minimizing the bearing load can thus prevent or minimize damage to the building. In addition, smaller fasteners, dowels, so-called Halfen rails, steel components, etc. can be used to save costs and labor during mounting.
Der Befestigungsanker 100 kann jedoch für sich oder auch integriert in ein Stahleinbauteil direkt in den Beton oder eine Betontasehe eingebaut bzw. eingegossen werden. Eine andere Möglichkeit besteht darin, den Befestigungsanker integriert oder einstückig alsTeil eines Pfostens, Rahmenträgers oder dergleichen vorzusehen.However, the fastening anchor 100 can be installed or cast in its own right or integrated into a steel component directly into the concrete or concrete lake. Another possibility is to provide the fastening anchor integrally or integrally as part of a post, frame support or the like.

Diese Zwischenschicht 150 kann somit weitere Energie absorbieren. Es ist auch denkbar, beim Anordnen der Zwischenschicht 150 auf die vertikalen stabförmigen Elemente 132 zu verzichten.Another possibility for energy absorption is to fill a gap between the

Obwohl es in den Figuren nicht gezeigt ist, kann der Befestigungsanker auch einstückig mit einem Trägerpfosten oder Rahmenelement eines Gebäudes ausgebildet sein. Alternativ kann ein einzelner Befestigungsanker anstatt mit einem Gebäudeelement verschraubt zu werden, in eine Betondecke eingegossen werden. Die Stege und stabförmigen Elemente sind nicht auf die hier gezeigten Ausführungsbeispiele beschränkt, sondern können jede andere Formgebung haben, um ein bestimmtes Absorptionsverhalten bzw. Energieabsorption bzw. Dämpfung zu erzielen. Beispielsweise müssen die Schlitze zum Bilden der Aussparungen 124 nicht immer Längsschlitze sein, sondern können jede andere Form wie beispielsweise dreieckig, oval, sägezahnförmig, wellenförmig, meanderförmig etc. aufweisen. Die in
Die Schräge 128a muß nicht eine Gerade sein, sondern kann auch bogen- oder kurvenförmig oder gezahnt, wellenförmig oder dergleichen sein. Die Stege 122, 123 müssen nicht, wie in den Ausführungsbeispielen gezeigt, eine rechteckige Querschnittsform haben, sondern können auch eine ovale runde oder jede andere Querschnittsform haben. Derart kann ein Verformungsverhalten bzw. eine Energieabsorption beliebig erzielt werden.The
Darüber hinaus können in die Schlitze bzw. Bohrungen bzw. Aussparungen bzw. Vertiefungen bzw. Querschnittsschwächungen 124 beliebige Füllmaterialien eingebracht werden, um eine zusätzliche Dämpfung bzw. Abschwächung der Auflagerlasten zu erreichen.In addition, 124 any filler materials can be introduced into the slots or holes or recesses or depressions or cross-sectional weakenings, in order to achieve additional damping or weakening of the bearing loads.
