Definitions
- the present invention relates to a device for reinforcing concrete structures according to the preamble of patent claim 1.
- Concrete structures used as ceilings, walls and beams are used in all modern buildings to house media pipes for water, sewage, ventilation, electrical and communication. Because ventilation pipes usually have large diameters, these were built separately for buildings with air conditioning systems and the ventilation ducts are often rectangular, so that they can be used in infrastructure, eg. B. could be hidden in suspended ceilings. In the context of energy saving, which is increasingly being used, more and more pipes and ducts for forced ventilation have been installed. This entails that ventilation ducts of large cross section must be inserted. Since no one appreciates publicly laid pipes in private homes and commercial buildings, which in addition to aesthetic defects are also dust collectors and dirt zones and reduce the room height, more and more pipes are installed in the concrete structure.
- a structural steel construction is specified as reinforcement for a concrete slab element, a concrete floor or a concrete floor with integrated heating or cooling function, which has at least one reinforcing grid and attached carrier for the heating or cooling pipes.
- the publication EP 1 207 354 A2 shows a support strip for a reinforcement for sheet-like elements of hardenable material.
- the presented support bar has clamping points where, for example, lines or heating / cooling pipes can be connected.
- the font DE 19937414A1 describes a device by means of which recesses in the support area of flat slabs of reinforced concrete or prestressed concrete can be reinforced.
- the problem is recognized that the arrangement of recesses has a fundamental influence on the carrying capacity of the construction. It is also recognized that there must be the possibility of such devices even during construction, just before pouring the concrete, to be installed.
- This disclosure only relates to conduits routed perpendicular to the ceiling and through the ceiling in the immediate vicinity of the support and solves the problems of puncture resistance.
- the problem is more diverse and often causes problems for the structural engineers, because it is difficult to estimate on site and at the time of acceptance and / or control of the reinforcement, how much the strength is weakened by accumulations of media lines and media lines of large diameter, and how to proceed if it is suspected that the load capacity of a concrete structure is insufficient.
- the more perfect an installation is performed today by the plumbing, electrical and ventilation installer the more and, above all, the greater the number and diameter of the pipes that will be built into a concrete structure for later placement of the media lines.
- the structural engineer is usually not reported, he is confronted with the facts on the spot and must take the reinforcement usually under time pressure.
- the present invention now has the object with a component to improve the concrete structures of the type mentioned in such a way that in the planning phase means are made available, which can be used locally reduce the weakenings by media lines or even eliminated.
- means can be made available that can be installed locally at the time of removal of the reinforcement, which ensures the reinforcement of the concrete structure after pouring the concrete by means of clear and for the civil engineer by means of easily recognizable force model in the field of media lines the Reinforced shear behavior such that the statics of the concrete structure corresponds to the originally made by the structural engineer with the calculation of the reinforcement design either completely or at least approximated.
- Basis of the invention is a method that allows the civil engineer both in the planning phase as well as locally using components with force models to take effective measures to reinforce the conventionally reinforced concrete construction locally by suitable means in such a way that the construction is not excessive by media lines weakened, respectively, unnecessary unnecessary oversizing of the same must lead to uneconomical building structures.
- the deposits referred to as internals 20 and media lines are surrounded by means of components 1,21,22,23, which transmit forces and form clearly recognizable force-neutral zones 31.
- the shear forces act 16,16 '.
- the figures show such structures in each case in the horizontal arrangement, but apply to any position.

- the pressure forces are through the concrete 12 and other parts of the device 1 such as those in Fig. 21 . 22 taken extensions 8, while for receiving the thrust forces 16,16 'a ZD component 21 with at least one tension element 2 is used.
- the SB Force Model 41 is in Fig. 2 shown.
- the force neutral zone 31 is made possible by an MQ zone 37, which can transmit the bending moments 34 and the thrust forces 36.
- the bending moments 34 and the thrust forces 36 are taken over by an SB component 22 with at least one rigid element 6.
- Any two force models and force-neutral zones can be combined by the connection via an HS force model 42 in such a way that a horizontal thrust zone 35 is formed which absorbs the horizontal thrust forces 18 (FIG. Fig. 3 ).
- the same combination can be made with an SB Force Model 41 and the HS Force Model 42, but this is not shown in the drawing.
- the invention ensures in the region of said cavities in the transverse direction, the necessary shear behavior by creating a clear flow of forces.
- the resulting tensile component is taken from the thrust forces (eg, truss model) by the systems and devices described below. It is created locally by the systems an armored area for power transmission. This happens according to the force model by means such as e.g. Arm michsbügel, frame systems, rings, dowels and the like which are described below.
- It allows the necessary arrangement and guidance of the media lines and the suspension of the resulting tensile forces in such a way that the necessary power flows and concrete pressure diagonals can form. This is done by arranged on the above systems and devices loops, straps, iron, etc. It is also possible to leave the media lines in place and to arrange the new components 1 so that the necessary pressure diagonals can form freely despite the media lines.

- These anchors 3 may consist of round or square upsets, conventional end anchorages such as welded crossbars or bends. They always serve to anchor the drawbar 2 in the concrete 12 after pouring.
- Fig. 6 shows a built-ZD component 21.
- the printed diagonal 30 act on the connected to the anchors 3, 3 'tie rod 2, so that the internals 20 can be accommodated in a force-neutral zone 31.
- the ZD component 21 takes over the transmission of forces, so that even when installing many and / or large installations 20 such.
- B. media lines the concrete structure 10 with a previously designed and existing conventional armor 11 statically little or not weakened.
- a holder 4 fixed or detachable connected In order to keep the internals 20 during the pouring of the concrete 12 in the force-neutral zone 31, so in the space provided for the leadership of the fixtures 20, with the drawbar 2 or the anchors 3, 3 ', a holder 4 fixed or detachable connected.
- This consists z. B. from rods, bands or loops with which the possible cavity for the management of the media lines is controlled and defined.

- the tension element 2 also forms the holder 4 for the fixtures 20.
- Elements shown in these figures are suitable for planned installation, so that the craftsmen are given where they may and should lay their media lines. Will a device 21, 22 or 23 at an early stage dhz B. already provided in the planning by the plumber, the ventilation technician or the electrician, this can introduce its lines in the brackets 4 of the already existing on-site components 21, 22 or 23.
- the invention thus offers the builders a way to provide the static security for the installation of fixtures 20 at an early stage.
- a plurality of components 21, 22 and / or 23 can be connected by connections 5 (FIG. Fig. 12 ). This is necessary if there is a risk that could be moved by the pouring of the concrete 12, the components 21, 22 and / or 23 and thereby would not act exactly at the place where the civil engineer wants the reinforcement.
- the anchorage 3 does not have to be an upset or a welded part as described above.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Verstärkung von Betonbauten gemäß Oberbegriff des Patentanspruchs 1.The present invention relates to a device for reinforcing concrete structures according to the preamble of
Betonkonstruktionen die als Decken, Wände und Träger eingesetzt werden, dienen unter anderen in allen modernen Bauten der Unterbringung von Medienleitungen für Wasser, Abwasser, Lüftung, Elektro und Kommunikation. Weil Lüftungsrohre normalerweise große Durchmesser aufweisen, wurden diese für Gebäude mit KlimaAnlagen separat gebaut und die Lüftungskanäle vielfach rechteckig ausgestaltet, so dass sie in der Infrastruktur, z. B. in herunter gehängten Decken versteckt werden konnten. Im Zusammenhang mit dem Energiesparen, das immer mehr Anwendung findet, wurden immer mehr Rohre und Kanäle für Zwangslüftungen eingebaut. Dies bringt es mit sich, dass Lüftungsleitungen großen Querschnitts eingelegt werden müssen. Da Niemand in Privathäusern und Geschäftsgebäuden offen verlegte Leitungen schätzt, die nebst ästhetischen Mängeln auch Staubfänger und Schmutzzonen sind und die Raumhöhe vermindern, werden vermehrt Leitungen in die Betonkonstruktion eingebaut.Concrete structures used as ceilings, walls and beams, among other things, are used in all modern buildings to house media pipes for water, sewage, ventilation, electrical and communication. Because ventilation pipes usually have large diameters, these were built separately for buildings with air conditioning systems and the ventilation ducts are often rectangular, so that they can be used in infrastructure, eg. B. could be hidden in suspended ceilings. In the context of energy saving, which is increasingly being used, more and more pipes and ducts for forced ventilation have been installed. This entails that ventilation ducts of large cross section must be inserted. Since no one appreciates publicly laid pipes in private homes and commercial buildings, which in addition to aesthetic defects are also dust collectors and dirt zones and reduce the room height, more and more pipes are installed in the concrete structure.
Allgemein werden durch fortschreitende Bedürfnisse des Komforts mehr Leerrohre für Medienleitungen wie Elektro, Audio, Heizungen und Wasser eingelegt, so dass in vielen Fällen eine akute Schwächung der Betonkonstruktionen vorliegt.In general, as comfort needs to progress, more conduits for media lines such as electric, audio, heaters, and water are being inserted, so that in many cases there is an acute weakening of the concrete structures.
Im Umfeld solcher Medienleitungen entstehen in der Betonkonstruktion mehrere Hohlräume mit einer Längenausdehnung die oftmals große Bereiche der Betonkonstruktion durchlaufen. Dadurch wird insbesondere das Schubtragverhalten der Betonkonstruktionen massiv beeinträchtigt.In the environment of such media lines arise in the concrete structure several cavities with a longitudinal extent often go through large areas of the concrete structure. As a result, in particular the shear behavior of the concrete structures is massively impaired.
Insbesondere für das Funktionieren der Statik z. B. einer armierten Stahlbetondecke ist jedoch die Schubtragfähigkeit von entscheidender Wichtigkeit.In particular, for the functioning of the static z. As a reinforced reinforced concrete ceiling, however, the shear capacity is of crucial importance.
Bisher bekannte Durchstanzsysteme erlauben nur Verstärkungen der Betonkonstruktion im Bereich von Krafteinleitungsbereichen von Stützen und dergleichen. Sie sind nicht geeignet die Probleme, welche durch Medienleitungen verursachte Schwächungen inmitten von Betonkonstruktionen bringen, zu lösen. Dies insbesondere deshalb, weil für die ermittelte Tragfähigkeit dieser Durchstanzsysteme ein voller Betonquerschnitt ohne Einlagen (z. B. Medienleitungen) vorhanden sein muss. Solche Einlagen schaffen jedoch große Zonen ohne Tragfähigkeit. Dies müsste berücksichtigt werden, indem spezielle Vorrichtungen lokal am Ort der Schwächung eingebaut werden. Solche Vorrichtungen sind bis heute nicht bekannt.Previously known punching systems allow only reinforcements of the concrete structure in the range of force introduction areas of columns and the like. They are not suitable for solving the problems caused by media lines causing weakening in the midst of concrete structures. This is particularly because a full concrete cross-section without inserts (eg media lines) must be present for the determined carrying capacity of these puncturing systems. Such deposits, however, create large zones without carrying capacity. This would have to be taken into account by installing special devices locally at the point of weakening. Such devices are not known until today.
In der 200 22 421 U1 ist eine Baustahlkonstruktion als Bewehrung für ein Betonplattenelement, eine Betondecke oder einen Betonfußboden mit integrierter Heiz- oder Kühlfunktion angegeben, die zumindest ein Bewehrungsgitter und daran angebrachte Träger für die Heiz- bzw. Kühlrohre aufweist.In the 200 22 421 U1 a structural steel construction is specified as reinforcement for a concrete slab element, a concrete floor or a concrete floor with integrated heating or cooling function, which has at least one reinforcing grid and attached carrier for the heating or cooling pipes.

Diese Offenbarung betrifft nur senkrecht zur Decke und durch die Decke geführte Leitungen in unmittelbarer Stützennähe und löst die Probleme in Bezug auf Durchstanzfestigkeit. Die Problematik ist aber vielfältiger und bereitet den Baustatikern oft Probleme, weil vor Ort und zum Zeitpunkt der Abnahme und/oder Kontrolle der Armierung schwer abzuschätzen ist, wie stark die Festigkeit durch Ansammlungen von Medienleitungen und Medienleitungen großer Durchmesser, geschwächt wird und wie verfahren werden soll, wenn vermutet wird, dass die Tragfähigkeit einer Betonkonstruktion ungenügend ist. Je perfekter heute eine Installation durch den Sanitär-, den Elektro- und den Lüftungsinstallateur ausgeführt wird, desto mehr und vor allem, desto grösser werden die Anzahl und die Durchmesser der Rohre, die für die spätere Unterbringung der Medienleitungen in eine Betonkonstruktion eingebaut werden. Dem Baustatiker wird normalerweise keine Meldung gemacht, er wird vor Ort mit den Tatsachen konfrontiert und muss die Armierung in der Regel unter Zeitdruck abnehmen.This disclosure only relates to conduits routed perpendicular to the ceiling and through the ceiling in the immediate vicinity of the support and solves the problems of puncture resistance. However, the problem is more diverse and often causes problems for the structural engineers, because it is difficult to estimate on site and at the time of acceptance and / or control of the reinforcement, how much the strength is weakened by accumulations of media lines and media lines of large diameter, and how to proceed if it is suspected that the load capacity of a concrete structure is insufficient. The more perfect an installation is performed today by the plumbing, electrical and ventilation installer, the more and, above all, the greater the number and diameter of the pipes that will be built into a concrete structure for later placement of the media lines. The structural engineer is usually not reported, he is confronted with the facts on the spot and must take the reinforcement usually under time pressure.
Bei der statischen Planung, also bei der Auslegung der Armierung einer BetonKonstruktion wird dieser Tatsache bisher allenfalls bei der Dimensionierung von Trägern Beachtung geschenkt. Für Decken und Wände vertraut man auf die normalerweise mit Sicherheiten ausgelegte Armierung. Die Leitungen werden vor dem Eingießen des Betons, aber vielfach nach der Festlegung der statisch notwendigen Armierung durch die Arbeiter vor Ort eingelegt . Dem Bauingenieur der die Statik vor dem Eingießen des Betons abnehmen muss und für deren Qualität haftet, wird bisher kein Mittel zur Verfügung gestellt, mit dem er kurzfristig, mit einfachen Mitteln und vor Ort in der Konstruktion, eine statische Verstärkung einbauen könnte.In static planning, ie in the design of the reinforcement of a concrete construction, this fact has so far at best been taken into account when dimensioning girders. For ceilings and walls, rely on the normally collateralized reinforcement. The pipes are laid before the pouring of the concrete, but often after the determination of the statically necessary reinforcement by the workers on site. The civil engineer, who has to relieve the static before pouring the concrete and is responsible for its quality, has so far not been provided with a means by which he could install a static reinforcement at short notice, with simple means and on site in the construction.
Die vorliegende Erfindung stellt sich nunmehr die Aufgabe mit einem Bauelement die Betonkonstruktionen der eingangs genannten Art derart zu verbessern, dass in der Planungsphase Mittel zur Verfügung gestellt werden, welche lokal eingesetzt die Schwächungen durch Medienleitungen reduzieren oder gar eliminieren können. Jedoch auch Mittel zur Verfügung gestellt werden, die noch zum Zeitpunkt der Abnahme der Armierung lokal eingebaut werden können, wobei diese nach dem Eingießen des Betons die Verstärkung der Betonkonstruktion gewährleistet indem sie mittels klarem und für den Bauingenieur mittels leicht erkennbarem Kräftemodell im Bereich der Medienleitungen das Schubtragverhalten derart verstärkt, dass die Statik der Betonkonstruktion den ursprünglich durch den Baustatiker mit der Berechnung der Armierung vorgenommenen Auslegung entweder vollständig oder zumindest in Annäherung entspricht.The present invention now has the object with a component to improve the concrete structures of the type mentioned in such a way that in the planning phase means are made available, which can be used locally reduce the weakenings by media lines or even eliminated. However, means can be made available that can be installed locally at the time of removal of the reinforcement, which ensures the reinforcement of the concrete structure after pouring the concrete by means of clear and for the civil engineer by means of easily recognizable force model in the field of media lines the Reinforced shear behavior such that the statics of the concrete structure corresponds to the originally made by the structural engineer with the calculation of the reinforcement design either completely or at least approximated.
Diese Aufgabe löst ein Bauelement für Betonkonstruktionen mit den Merkmalen des Patentanspruches 1. Weitere erfindungsgemäße Merkmale gehen aus den abhängigen Ansprüchen hervor und deren Vorteile sind in der nachfolgenden Beschreibung erläutert.This object is achieved by a component for concrete structures with the features of
Grundlage der Erfindung ist ein Verfahren, das dem Bauingenieur erlaubt sowohl in der Planungsphase als auch vor Ort mittels Bauelementen mit Kräftemodellen wirksame Maßnahmen zu treffen, um die konventionell bewehrte Betonkonstruktion lokal durch geeignete Mittel in der Art zu verstärken, dass die Baukonstruktion nicht durch Medienleitungen übermäßig geschwächt wird respektive, nicht unnötige Überdimensionierungen derselben zu unwirtschaftlichen Baukonstruktionen führen müssen. Zu diesem Zweck werden die in der Folge als Einbauten 20 bezeichneten Einlagen und Medienleitungen mittels Bauelementen 1,21,22,23 umgeben, welche Kräfte übertragen und klar erkennbare kraftneutrale Zonen 31 bilden. Auf jede Betonkonstruktion wirken die Schubkräfte 16,16'. Die Figuren zeigen solche Baukonstruktionen jeweils in der Horizontalen Anordnung, gelten aber für jede beliebigen Lage.Basis of the invention is a method that allows the civil engineer both in the planning phase as well as locally using components with force models to take effective measures to reinforce the conventionally reinforced concrete construction locally by suitable means in such a way that the construction is not excessive by media lines weakened, respectively, unnecessary unnecessary oversizing of the same must lead to uneconomical building structures. For this purpose, the deposits referred to as

Die Figuren stellen mögliche Ausführungsbeispiele dar, welche in der nachfolgenden Beschreibung erläutert werden.The figures represent possible embodiments, which will be explained in the following description.
Die Erfindung gewährleistet im Bereich der genannten Hohlräume in Querrichtung das notwendige Schubtragverhalten durch Schaffung eines klaren Kräfteflusses. So wird die entstehende Zugkomponente herrührend von den Schubkräften (z. B. Fachwerk-Modell) durch die nachfolgend beschriebenen Systeme und Vorrichtungen aufgenommen. Es wird lokal durch die Systeme ein armierter Bereich für die Kraftübertragung geschaffen. Dies geschieht je nach Kräftemodell durch Mittel wie z.B. Armierungsbügel, Rahmensysteme, Ringe, Dübel und dergleichen die nachfolgend beschrieben sind. Es resultiert ein erhöhter Schubwiderstand der Betonkonstruktion. Sie ermöglicht die notwendige Anordnung und Führung der Medienleitungen und die Aufhängung der entstehenden Zugkräfte dergestalt, dass die notwendigen Kräfteflüsse und Betondruckdiagonalen sich ausbilden können. Dies geschieht durch an die oben genannten Systeme und Vorrichtungen angeordneten Schlaufen, Bänder, Eisen etc. Ebenso ist es möglich, die Medienleitungen an Ort zu lassen und die neuen Bauelemente 1 so anzuordnen, dass sich die notwendigen Druckdiagonalen trotz der Medienleitungen frei ausbilden können.The invention ensures in the region of said cavities in the transverse direction, the necessary shear behavior by creating a clear flow of forces. Thus, the resulting tensile component is taken from the thrust forces (eg, truss model) by the systems and devices described below. It is created locally by the systems an armored area for power transmission. This happens according to the force model by means such as e.g. Armierungsbügel, frame systems, rings, dowels and the like which are described below. This results in an increased shear resistance of the concrete structure. It allows the necessary arrangement and guidance of the media lines and the suspension of the resulting tensile forces in such a way that the necessary power flows and concrete pressure diagonals can form. This is done by arranged on the above systems and devices loops, straps, iron, etc. It is also possible to leave the media lines in place and to arrange the
Ein der Erfindung zugrunde liegende Ausführung des Bauelementes 1, das ZD-Bauelement 21 ist in den
Um die Einbauten 20 auch während des Eingießens des Betons 12 in der kraftneutralen Zone 31, also in dem dafür vorgesehenen Hohlraum für die Führung der Einbauten 20 zu halten, wird mit der Zugstange 2 oder den Verankerungen 3, 3' eine Halterung 4 fest oder lösbar verbunden. Diese besteht z. B. aus Stäben, Bändern oder Schlaufen mit welchen der mögliche Hohlraum für die Führung der Medienleitungen gesteuert und definiert wird. In
Andere Ausführungsformen sind in den
Um die Position mehrerer Bauelemente 21,22 und/oder 23 in Längsrichtung der kraftneutralen Zone 31 festzulegen, können mehrere Bauelemente 21,22 und/oder 23 durch Verbindungen 5 (
Die Verankerung 3 muss nicht, wie oben beschrieben, eine Aufstauchung oder ein angeschweißtes Teil sein. Wie in
Gerade im modernen Bau der den Anforderungen der Gebäude Organisation (Facility-Management) genügen muss werden oft sehr viele einbauten 20, vor allem auch Medienleitungen mit großen Durchmessern eingebaut. Sollte dies nicht schon zum Zeitpunkt der statischen Auslegung der Betonkonstruktion bekannt gewesen sein, kann es zu großen Problemen führen. Es ist deshalb denkbar, dass eine Vielzahl von kreuzweise angeordneten Kombinationen von winklig abgebogenen Elementen aus Zugstangen 2 und Verankerungen 3 eingesetzt werden. Auf diese Weise wird wie in
In gewissen Fällen kann es sich lohnen oder ist es erforderlich, speziell geformte SB-Bauelemente 22 einzusetzen.
Grundsätzlich sollen Varianten vorgestellt werden, die dem Baustatiker ermöglichen, auch im letzten Moment vor dem Eingießen des Betons 12 noch Vorkehrungen zu treffen, dass die Betonkonstruktion 10 keine Schwachstellen aufweist und den Anforderungen entspricht. Es sei nicht das Ziel, dass man die konventionelle Armierung weniger stabil auslege. Das Ziel ist es vielmehr durch ungeplante Einbauten verursachte Schwächungen reduzieren oder sogar eliminieren zu können.Basically, variants are to be presented, which allow the structural engineer, even at the last moment before pouring the concrete 12 to make arrangements that the

Wesentlichster Teil der ZD-Bauelemente 21' - 21'" ist die Zugstange 2, 2'. Diese wirkt als Zugbandelement in beiden Richtungen. Um die ZD-Bauelemente 21' - 21'" im Beton sicher zu verankern, wird es an den Enden mit Verankerungen 3 ausgestattet Die Verankerungen 3 bestehen z. B. aus angeschweißten Quereisen, geschraubten Ansätzen, Aufstauchungen oder Abbiegungen. Sie dienen der Verankerung der Zugstange 2, 2' im Beton nach dem Eingießen. Dazu können die in den
Die ZD-Bauelemente 21' - 21'" übernehmen die Übertragung der Kräfte lokal und können an beliebigen Stellen, auch mehrfach eingesetzt werden. Beim Einbau vieler und großer Einbauten 20 wird die Betonkonstruktion 10 mit einer bereits ausgelegten und vorhandenen konventionellen Armierung 11 statisch wenig oder gar nicht geschwächt. Die durch Einbauten 20 verursachten lokalen Schwächungen werden durch den Einsatz von erfindungsgemäßen ZD-Bauelementen 21'-21'" kompensiert.The ZD components 21 '- 21' "take over the transmission of forces locally and can be used multiple times at any point.In the installation of many and
