Definitions
- the invention relates to a component for thermal insulation in buildings, in particular with projecting wall parts, with an elongated insulating body made of thermally insulating material and with metal reinforcement elements which protrude laterally for anchoring, the component being designed as a finished part.
- Such a component is known from DE-PS 30 05 571.
- This component has a thrust bearing to absorb horizontal forces.
- the reinforcement elements run partially at an angle through the insulating body. This enables you to absorb vertical forces.
- Such components are unsuitable, however, if no moment forces, but only vertical forces are to be absorbed. This is the case, for example, when the projecting wall part is supported by supports on the side facing away from the building. Even with three-sided or two-sided balcony slabs, essentially only vertical forces occur. Even in the event of the occurrence of only vertical forces, the known component requires a thrust bearing, since the oblique course of the reinforcement elements within the component causes horizontal forces to occur, which must be absorbed by the thrust bearing, even when there is only vertical loading.
- a heat-insulating prefabricated component with an insulating body 4 is arranged in a known manner.
- the longitudinal direction of this insulating body 4 extends perpendicular to the cutting plane.
- This insulating body 4 are located at predetermined intervals in the longitudinal direction from each other vertically extending steel rods 5 for absorbing the vertical forces.
- This arrangement of the steel rods 5 serving as reinforcement elements does not produce any horizontal forces when the vertical forces are absorbed, so that thrust bearings are not required.
- the cantilevered concrete slab 3 is preferably suspended. In this way, movements caused by temperature fluctuations can be recorded particularly advantageously.
- the steel rods 5 horizontally extending made of steel cantilever parts 6 and 7 are connected at their ends.
- the cantilever 6 extends into the concrete ceiling 2, while the cantilever 7 extends into the balcony slab 3.
- These cantilever parts serve to absorb the cantilever forces from the concrete ceiling 2 or balcony slab 3.
- the vertical free length of the steel rod 5 between the cantilever parts 6 and 7 and the type of attachment to the cantilever parts determines the maximum mobility of the balcony.
- the reinforcement element here consists of a bent steel rod 8.
- This steel rod is guided vertically through the insulating body 4 'or 4 "in the middle section, while its two ends sections are bent so that they run in the horizontal direction.
- One end section extends into the concrete ceiling of the building and the other end section extends into the projecting balcony slab.
- the insulating body 4 'in FIG. 2 has 8 depressions or incisions 9 and 10 in the region of the horizontal sections of the steel rod, which can be filled with concrete.
- the steel rod 8 is thus firmly concreted in the area of the upper and lower bend. There remains a vertically extending central section in which the steel rod is freely guided through the insulating body 4 'and therefore maintains its mobility.
- the cuts 9 and 10 can already be filled with concrete before the component is transported to the construction site.
- Another possibility is that the insulating elements are delivered to the construction site with the steel rods passed through and the incisions 9 and 10 are only filled there when the adjacent components are concreted.
Abstract
Description
Die Erfindung betrifft ein Bauelement zur Wärmedämmung bei Gebäuden, insbesondere bei vorkragenden Wandteilen, mit einem länglichen Isolierkörper aus thermisch isolierendem Material und mit metallenen Bewehrungselementen, die seitlich zur Verankerung vorstehen, wobei das Bauelement als Fertigteil ausgebildet ist.The invention relates to a component for thermal insulation in buildings, in particular with projecting wall parts, with an elongated insulating body made of thermally insulating material and with metal reinforcement elements which protrude laterally for anchoring, the component being designed as a finished part.
Ein derartiges Bauelement ist durch die DE-PS 30 05 571 bekannt. Dieses Bauelement besitzt ein Drucklager zur Aufnahme horizontaler Kräfte. Die Bewehrungselemente verlaufen teilweise schräg durch den Isolierkörper. Sie sind dadurch in der Lage, auch vertikale Kräfte aufnehmen zu können. Derartige Bauelemente sind jedoch dann ungeeignet, wenn keine Momentkräfte, sondern nur vertikale Kräfte aufzunehmen sind. Dies ist beispielsweise dann der Fall, wenn das vorkragende Wandteil auf der dem Gebäude abgewandten Seite von Stützen getragen wird. Auch bei dreiseitig oder zweiseitig aufliegenden Balkonplatten treten im wesentlichen nur vertikale Kräfte auf. Auch im Falle des Auftretens nur vertikaler Kräfte benötigt das bekannte Bauelement ein Drucklager, da durch den Schrägverlauf der Bewehrungselemente innerhalb des Bauelementes auch bei ausschließlich vertikaler Belastung horizontale Kräfte auftreten, die vom Drucklager aufgenommen werden müssen. Ein weiterer Nachteil besteht bei mehrseitig gelagerten Balkonplatten darin, daß durch Temperaturschwankungen im Balkon unterschiedliche Zugkräfte durch die Querstäbe aufgenommen werden müssen. Wenn der Balkon schrumpft, dann entstehen zusätzliche Zugkräfte, wodurch der Balkon leicht angehoben wird. Wenn der Balkon sich streckt, dann entstehen Druckkräfte, durch die sich der Balkon etwas senkt. Außerdem wird bei zweiseitig aufliegenden Balkonen deren Länge durch die wie eine Einspannung wirkende Verbindung über das Bauelement begrenzt. Bei einem an der dem Gebäude gegenüberliegenden Seite auf Stützen gelagerten Wandteil entstehen durch dessen elastische Durchbiegung in den Drucklagern außer der rechnerisch erfassbaren Druckkraft zusätzliche Druckkräfte, die rechnerisch nicht mehr bestimmbar sind.Such a component is known from DE-PS 30 05 571. This component has a thrust bearing to absorb horizontal forces. The reinforcement elements run partially at an angle through the insulating body. This enables you to absorb vertical forces. Such components are unsuitable, however, if no moment forces, but only vertical forces are to be absorbed. This is the case, for example, when the projecting wall part is supported by supports on the side facing away from the building. Even with three-sided or two-sided balcony slabs, essentially only vertical forces occur. Even in the event of the occurrence of only vertical forces, the known component requires a thrust bearing, since the oblique course of the reinforcement elements within the component causes horizontal forces to occur, which must be absorbed by the thrust bearing, even when there is only vertical loading. Another disadvantage of multi-sided balcony slabs is that due to temperature fluctuations in the balcony, different tensile forces have to be absorbed by the cross bars. If the balcony shrinks, additional tensile forces are created which raise the balcony slightly. When the balcony stretches, compressive forces are created which lower the balcony somewhat. In addition, in the case of balconies resting on two sides, their length is limited by the connection via the component acting as a clamping. At a On the side of the wall mounted on supports opposite the building, its elastic deflection in the thrust bearings creates additional compressive forces in addition to the arithmetically detectable compressive force, which can no longer be determined arithmetically.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Bauelement zur Wärmedämmung bei Gebäuden zu schaffen, bei dem Drucklager nicht erforderlich sind und bei dem Temperaturschwankungen keine zusätzlichen Belastungen der Bewehrungselemente hervorrufen.It is therefore the object of the present invention to provide a component for thermal insulation in buildings in which pressure bearings are not required and in which temperature fluctuations do not cause any additional loads on the reinforcement elements.
Diese Aufgabe wird bei dem anfangs genannten Bauelement erfindungsgemäß dadurch gelöst, daß die Bewehrungselemente innerhalb des Isolierelementes senkrecht verlaufen.This object is achieved according to the invention in the initially mentioned component in that the reinforcement elements run vertically within the insulating element.
Die Erfindung wird im folgenden anhand von in den Figuren dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail below with reference to exemplary embodiments shown in the figures.
Es zeigen:
- Fig. 1 einen senkrechten Querschnitt durch ein erstes Ausführungsbeispiel des Bauelementes im eingebauten Zustand,
- Fig. 2 einen senkrechten Querschnitt durch ein zweites Ausführungsbeispiel eines Bauelementes und
- Fig. 3 einen senkrechten Querschnitt durch ein drittes Ausführungsbeispiel eines Bauelementes.
- 1 is a vertical cross section through a first embodiment of the component in the installed state,
- Fig. 2 is a vertical cross section through a second embodiment of a component and
- Fig. 3 shows a vertical cross section through a third embodiment of a component.
Fig. 1 zeigt Teile eines Gebäudes, beispielsweise eine Gebäudewand 1, eine Betondecke 2 sowie ein ebenfalls aus Beton bestehendes vorkragendes Gebäudeteil, beispielsweise eine Balkonplatte 3. Zwischen diesen ist in bekannter Weise ein wärmedämmendes Fertigbauteil mit einem Isolierkörper 4 angeordnet. Die Längsrichtung dieses Isolierkörpers 4 erstreckt sich senkrecht zur Schnittebene. In diesem Isolierkörper 4 befinden sich in vorbestimmten Abständen in Längsrichtung voneinander angeordnete vertikal verlaufende Stahlstäbe 5 zur Aufnahme der vertikalen Kräfte. Durch diese Anordnung der als Bewehrungselemente dienenden Stahlstäbe 5 entstehen bei der Aufnahme der vertikalen Kräfte keine Horizontalkräfte, so daß Drucklager nicht erforderlich sind. Die auskragende Betonplatte 3 ist vorzugsweise hängend gelagert. Auf diese Weise können durch Temperaturschwankungen bedingte Bewegungen besonders vorteilhaft aufgenommen werden.1 shows parts of a building, for example a building wall 1, a
Mit den Stahlstäben 5 sind an deren Enden horizontal verlaufende, aus Stahl bestehende Kragteile 6 und 7 verbunden. Das Kragteil 6 erstreckt sich dabei in die Betondecke 2, während das Kragteil 7 in die Balkonplatte 3 hineinragt. Diese Kragteile dienen zur Aufnahme der Kragkräfte von der Betondecke 2 bzw. Balkonplatte 3. Die senkrechte freie Länge des Stahlstabes 5 zwischen den Kragteilen 6 und 7 sowie die Art der Befestigung an den Kragteilen bestimmt die maximale Beweglichkeit des Balkons.With the
Die Fig. 2 und 3 zeigen besonders wirtschaftlich herzustellende Bauelemente. Das Bewehrungselement besteht hier aus einem gebogenen Stahlstab 8. Dieser Stahlstab ist im mittleren Abschnitt senkrecht durch den Isolierkörper 4' bzw. 4" geführt, während seine beiden Endabschnitte so abgebogen sind, daß sie in horizontaler Richtung verlaufen. Dabei erstrecken sich der eine Endabschnitt in die Betondecke des Gebäudes und der andere Endabschnitt in die vorkragende Balkonplatte. Der Isolierkörper 4' in Fig. 2 weist im Bereich der horizontalen Abschnitte des Stahlstabes 8 Vertiefungen bzw. Einschnitte 9 und 10 auf, die mit Beton gefüllt werden können. Damit ist der Stahlstab 8 im Bereich der oberen und unteren Biegung fest einbetoniert. Es verbleibt ein senkrecht verlaufender Mittelabschnitt, in dem der Stahlstab frei durch den Isolierkörper 4' geführt ist und deshalb seine Beweglichkeit erhält. Bei dem in Fig. 2 dargestellten Bauelement können die Einschnitte 9 und 10 bereits mit Beton gefüllt sein, bevor das Bauelement zur Baustelle transportiert wird. Eine weitere Möglichkeit besteht darin, daß die Isolierelemente mit den durchgeführten Stahlstäben zur Baustelle geliefert werden und erst dort beim Betonieren der angrenzenden Bauteile die Einschnitte 9 und 10 gefüllt werden.2 and 3 show components which can be produced particularly economically. The reinforcement element here consists of a
Der Isolierkörper 4" gemäß Fig. 3 weist im Bereich der horizontalen Abschnitte der Stahlstäbe 8 keine getrennten Einschnitte mehr auf, sondern er ist durchgehend in entsprechender Weise geformt. Er weist daher einen oberen und einen unteren vertikalen Teil auf, die in horizontaler Richtung gegeneinander versetzt sind. Der mittlere Teil verbindet den oberen und den unteren Teil, derart, daß seine obere und seine untere Kante schräg verlaufen. Der Stahlstab 8 ist nur in seinem vertikal verlaufenden Bereich durch den Isolierkörper 4" geführt, so daß die Biegestellen und die horizontal verlaufenden Abschnitte frei bleiben. Diese werden beim Betonieren der Gebäudedecke bzw. der Balkonplatte von Beton umschlossen. Es entsteht auf diese Weise sowohl auf der Deckenseite als auch auf der Balkonseite je eine durchgehende Kragbank.3 no longer has separate incisions in the area of the horizontal sections of the
