Abstract
Description
Die Erfindung betrifft ein Stahlbetonteil zur Herstellung von Fundamenten für Bauwerke, wobei das Stahlbetonteil aus zwei gleichartigen handelsüblichen Fertigdekkenelementen besteht, die jeweils eine im wesentlichen rechteckförmige, im Verlegezustand des Stahlbetonteils vertikal ausgerichtete Betonplatte und mindestens einen mit dieser verbundenen Gitterträger aus Stahl aufweisen, die beiden Fertigdeckenelemente spiegelbildlich so angeordnet sind, daß sich ihre Betonplatten in parallelem Abstand voneinander befinden und ihre Gitterträger einander zugewandt sind, und die benachbarten Gitterträger durch wenigstens ein an den Obergurten derselben angebrachtes längliches Zwischenstück fest miteinander verbunden sind.The invention relates to a reinforced concrete part for the production of foundations for buildings, wherein the reinforced concrete part of two similar commercial Fertigdekkenelementen each consisting of a substantially rectangular, in the laying state of reinforced concrete part vertically oriented concrete slab and at least have a connected with this lattice girder made of steel, the two finished ceiling elements mirror images are arranged so that their concrete slabs in parallel spaced from each other and their lattice girders facing each other and the adjacent lattice girders through at least one of the upper girths the same attached elongate spacer are firmly connected.
Bei den allgemein bekannten Fundamentkonstruktionen werden üblicherweise eine Bewehrung und Schalungswände vorgesehen (Einschalen). Die Schalungswände werden nach der Befüllung mit Ortbeton wieder entfernt (Ausschalen), während die Bewehrung im Beton verbleibt. Diese Methode hat den Nachteil, daß sie einen großen Zeit- bzw. Arbeitsaufwand erfordert, um ein Fundament auf der Baustelle herzustellen.In the well-known foundation constructions are usually a Reinforcement and formwork walls provided (shells). The formwork walls are removed after filling with in-situ concrete (stripping), while the Reinforcement remains in the concrete. This method has the disadvantage that it has a large Time or effort required to produce a foundation on the site.
Außerdem ist aus der deutschen Patentschrift DE 198 08 509 C1 ein Verfahren zum Herstellen eines zweischaligen Wandfertigteiles bekannt. Bei diesem Wandfertigteil sind Rundstähle vorgesehen, die mit den Obergurt-Rundstählen der Gitterträger verschweißt sind, und zwar so, daß die Rundstähle und die Obergurt-Rundstähle quer zueinander verlaufen. Dies bedeutet, daß die Rundstähle bei dem Wandfertigteil in der Einsatzstellung vertikal verlaufen. Dieses Wandfertigteil hat vor allem den Nachteil, daß bedingt durch die Form der Rundstähle und deren vertikale Ausrichtung kein nennenswerter Abstand zwischen den Obergurt-Rundstählen und damit zwischen den Betonplatten erreicht werden kann. Dies wirkt sich vor allem insoweit ungünstig aus, als die statische Belastbarkeit des Wandfertigkteils sehr begrenzt ist. In addition, from the German patent DE 198 08 509 C1 discloses a method for Making a clam shell prefabricated wall known. In this wall finished part are provided round steel, which with the upper flange round steel of the lattice girders are welded, in such a way that the round steel and the top flange round steel run transversely to each other. This means that the round steel in the wall prefabricated part run vertically in the operating position. This prefabricated wall has above all the Disadvantage that due to the shape of the round steel and its vertical orientation no significant distance between the upper flange round steel and thus can be achieved between the concrete slabs. This affects especially so far unfavorable, as the static load capacity of the wall Fertigkteils is very limited.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Stahlbetonteil zu schaffen, das die vorgenannten Nachteile vermeidet und gleichwohl ein einstückiges sowie einfach und kostengünstig herzustellendes Fertigteil ist, das auf der Baustelle ohne weitere Maßnahmen (d.h. Nacharbeiten bzw. Montage) problemlos und schnell plaziert werden kann.The invention is therefore an object of the invention to provide a reinforced concrete part, the avoid the aforementioned disadvantages and nevertheless a one-piece and easy and inexpensive to manufacture finished part is that on site without further Measures (i.e., rework or assembly) can be easily and quickly placed can.
Gelöst wird diese Aufgabe bei einem Stahlbetonteil der in Frage stehenden Art erfindungsgemäß dadurch, daß das Stahlbetonteil als ein einstückiges Fertigteil ausgebildet ist und sich jedes Zwischenstück starr und im wesentlichen horizontal zwischen den Obergurten der Gitterträger erstreckt.This object is achieved in a reinforced concrete part of the type in question according to the invention in that the reinforced concrete part is designed as a one-piece finished part and each intermediate piece is rigid and substantially horizontal between extends the upper straps of the lattice girders.
Das erfindungsgemäße Stahlbetonteil hat zunächst den Vorteil, daß die eingangs genannten Arbeitsvorgänge "Einschalen" und "Ausschalen" entfallen, was zu einer enormen Zeit- bzw. Arbeitsersparnis auf der Baustelle führt. Ferner ist das Stahlbetonteil vorteilhaft, weil die horizontale Ausrichtung des bzw. der Zwischenstücke(s) senkrecht zu den Betonplatten bzw. Obergurten eine beträchtliche Breite des Stahlbetonteils von mehr als zwei Metern und folglich eine vergleichsweise große statische Belastbarkeit und Stabilität ermöglicht, was für Fundamente bekanntlich von entscheidender Bedeutung ist.The reinforced concrete part according to the invention initially has the advantage that the beginning operations "shelling" and "stripping" are eliminated, resulting in a saves time and labor on the construction site. Furthermore, the reinforced concrete part advantageous because the horizontal orientation of the spacer or pieces (s) perpendicular to the concrete slabs or upper chords a considerable width of the reinforced concrete part of more than two meters and consequently a comparatively large static Resilience and stability allows for what is known for foundations is crucial.
Die für ein Fundament vorgesehenen, fertigen Stahlbetonteile werden zur Baustelle gebracht und dort lediglich in der erforderlichen Weise angeordnet. Anhand eines entsprechenden Verlegeplans kann dies sehr schnell erfolgen. Indem jedes für das Fundament vorgesehene Stahlbetonteil auf der Baustelle auf zwei Längskanten seiner Betonplatten gestellt wird, bilden diese Betonplatten Seitenwandungen, zwischen denen der Ortbeton eingebracht wird. Die Stahlbetonteile können dann sofort mit Ortbeton befüllt werden. Nach der Aushärtung des Betons ist das Fundament fertig. Auf dem Fundament kann das Bauwerk errichtet werden. Mit dem Stahlbetonteil lassen sich Fundamente verschiedenster Art herstellen (z.B. Streifenfundamente, Pfahlfundamente, Einzelfundamente usw.). Die Größe bzw. geometrischen Verhältnisse des erfindungsgemäßen Stahlbetonteils und seiner einzelnen Elemente richten sich nach den jeweiligen statischen Anforderungen hinsichtlich des betreffenden Bauwerkes, das auf dem Fundament stehen soll. The finished reinforced concrete parts intended for a foundation become the construction site brought and arranged there only in the required manner. Look at one This can be done very quickly according to the corresponding installation plan. By doing each for the Foundation provided reinforced concrete part on the construction site on two longitudinal edges of his Concrete slabs is placed, these concrete slabs form sidewalls, between where the in-situ concrete is introduced. The reinforced concrete parts can then immediately with In-situ concrete to be filled. After the concrete has hardened, the foundation is ready. The building can be erected on the foundation. Leave with the reinforced concrete part foundations of various kinds are produced (for example strip foundations, Pile foundations, single foundations, etc.). The size or geometric relationships of the reinforced concrete part according to the invention and its individual elements according to the respective static requirements with regard to the respective Building that should stand on the foundation.
Ein weiterer wesentlicher Vorteil des Stahlbetonteils liegt darin, daß bei seiner Herstellung handelsübliche Fertigdeckenelemente Verwendung finden. Die prinzipielle Ausbildung solcher bisher ausschließlich zur Herstellung von Decken vorgesehenen Fertigdeckenelemente läßt sich beispielsweise dem Faltblatt mit dem Titel "Plattendecke Verlegeanleitung" der Badische Drahtwerke GmbH in Kehl/Rhein (Deutschland) entnehmen. 'Another significant advantage of the reinforced concrete part is that in its manufacture commercially available finished ceiling elements find use. The principal Training such previously provided exclusively for the production of blankets Finished ceiling elements can be, for example, the leaflet titled "slab ceiling Laying instructions "of Badische Drahtwerke GmbH in Kehl / Rhein (Germany) remove. '
Demnach besteht ein Fertigdeckenelement grundsätzlich aus einer meist rechteckförmigen Betonplatte und mindestens einem mit dieser verbundenen Gitterträger aus Stahl. Nach einem bestimmten Verlegeplan werden die für eine Decke, zum Beispiel eine Geschoßdecke, vorgesehenen Fertigdeckenelemente in an sich bekannter Weise auf der Baustelle so angeordnet, daß sich deren Betonplatten unten befinden und mit ihrer planebenen Unterseite nach unten weisen, während deren Gitterträger nach oben weisen. Nach der Verlegung der Fertigdeckenelemente kann die Decke insgesamt mit Ortbeton vergossen werden. Die fertige Decke ist vergleichbar mit einer Vollbeton-Massivdecke. Der Unterschied liegt darin, daß die fertige Decke anschließend nicht verputzt werden muß. Es reicht aus, die Stoßfugen der Fertigdeckenelemente nach dem Betonieren zum Beispiel zu säubern oder zu verspachteln.Accordingly, a finished ceiling element basically consists of a generally rectangular Concrete slab and at least one connected to this lattice girder Stole. After a certain laying plan are those for a blanket, for example a floor ceiling, provided finished ceiling elements in a conventional manner arranged on the site so that their concrete slabs are located below and with their flat bottom side facing down, while their lattice girder after at the top. After laying the finished ceiling elements, the ceiling can be total be cast with in-situ concrete. The finished ceiling is comparable to one Full concrete solid slab. The difference is that the finished ceiling then does not have to be plastered. It is sufficient, the butt joints of the finished ceiling elements for example, after concreting to clean or fill.
Der senkrecht aus der Betonplatte herausragende Gitterträger eines handelsüblichen Fertigdeckenelementes weist in der Regel wenigstens einen Obergurt, einen der Gitterträgerhöhe entsprechend in parallelem Abstand zum Untergurt verlaufenden Untergurt sowie Ober- und Untergurt verbindende diagonale Abschnitte bzw. Diagonalen auf. Der Untergurt wird bei der Herstellung in die Betonplatte eingegossen und ist daher beim fertigen Fertigdeckenelement nicht mehr zu sehen. Die diagonalen Abschnitte bzw. Diagonalen dienen der Aufnahme der Schubkräfte, die in der Fuge zwischen Fertigdeckenelement und Ortbeton auftreten. Der Ober- und Untergurt sorgen für die notwendige Steifigkeit der Fertigdeckenelemente beim Einbau.The lattice girder of a commercial one protruding vertically from the concrete slab Fertigdeckenelementes usually has at least one upper flange, one of Lattice girder height corresponding to running in parallel distance to the lower chord Lower and upper and lower chords connecting diagonal sections or diagonals on. The lower flange is poured into the concrete plate during manufacture and is therefore no longer visible in the finished finished ceiling element. The diagonal Sections or diagonals serve to absorb the thrust forces in the joint occur between finished ceiling element and in-situ concrete. The upper and lower straps provide for the necessary rigidity of the finished ceiling elements during installation.
Durch die Verwendung von Fertigdeckenelementen handelsüblicher Art zur Herstellung der erfindungsgemäßen Stahlbetonteile ergibt sich auch insofern eine Kostenersparnis, als die Fertigdeckenelemente als solche sehr preisgünstig zu fertigen sind. Obwohl die Fertigdeckenelemente bisher nur zur Erstellung von Decken benutzt werden, eignen sie sich sehr gut zur Herstellung und sicheren Verwendung des erfindungsgemäßen Stahlbetonteils.By the use of prefabricated ceiling elements of commercial type for the production the reinforced concrete parts according to the invention also results in a cost savings, as the finished ceiling elements as such very inexpensive to manufacture are. Although the prefabricated ceiling elements previously used only for the creation of ceilings they are very well suited to the manufacture and safe use of the product Reinforced concrete part according to the invention.

Das in der Fig. 1 gezeigte Stahlbetonteil 1 besteht aus zwei fest miteinander verbundenen
gleichen Fertigdeckenelementen 2 und 3 und dient der Herstellung von Bauwerksfundamenten.
Das Fertigdeckenelement 3 ist als Einzelteil in den Fig. 2 und 3
dargestellt und handelsüblich hergestellt. The reinforced
Das Fertigdeckenelement 3 besteht aus einer rechteckförmigen Betonplatte 4 bestimmter
Dicke und drei mit dieser fest verbundenen und senkrecht aus dieser herausragenden
Gitterträgern 5-7 aus Stahl (Gitterträgertyp KT). Die Gitterträger 5 und
7 haben von dem Gitterträger 6 den gleichen parallelen Abstand. Sie weisen jeweils
einen Obergurt 8-10, jeweils zwei der Gitterträgerhöhe entsprechend in parallelem
Abstand zu dem zugehörigen Obergurt 8-10 verlaufende Untergurte und jeweils die
Obergurte 8-10 und Untergurte verbindende diagonale Abschnitte bzw. Diagonalen
11-13 auf. Die paarweise vorhandenen Untergurte eines Gitterträgers 5-7 werden bei
der Herstellung des Fertigdeckenelementes 3 in die Betonplatte 4 eingegossen und
sind daher in den Fig. 1 bis 3 nicht zu erkennen. Die Diagonalen 11-13 sind ebenfalls
paarweise angeordnet. Das heißt zum Beispiel im Falle des Gitterträgers 7, daß zwei
diagonal verlaufende Gitterträgerstäbe 13a, 13b der Diagonalen 13 von den betreffenden
parallelen Untergurten zum Obergurt 10 hin zusammenlaufen (Fig. 2).The finished
In Fig. 2 ist das Fertigdeckenelement 3 in dem Zustand zu sehen, in dem solche
Fertigdeckenelemente handelsüblicher Art bisher zur Herstellung von Decken, zum
Beispiel Geschoßdecken, verlegt werden. Die Betonplatte 4 liegt flach bzw. horizontal
und die Gitterträger 5-7 weisen nach oben, so daß der flüssige Ortbeton von oben
aufgebracht werden kann. Wenn dasselbe Fertigdeckenelement 3 um einen Winkel
von 90° um seine Längsmittelachse gegen den Uhrzeigersinn gedreht wird, erreicht
es die in Fig. 3 gezeigte Position. Es wird folglich "hochkantgestellt", und zwar auf die
untere Längskante 14 seiner Betonplatte 4.In Fig. 2, the
In der vorgenannten Weise hochkantgestellt und spiegelbildlich zueinander angeordnet
sind die beiden Fertigdeckenelemente 2 und 3 gemäß Fig. 1. Ihre jeweils auf
gleicher Höhe gegenüberliegenden bzw. einander zugewandten Gitterträger 5-7 bzw.
15-17, das heißt die Gitterträger 5-7 des rechten Fertigdeckenelementes 3 und die
Gitterträger 15-17 des linken Fertigdeckenelementes 2, sind durch die als Flachstäbe
ausgebildeten Zwischenstücke 18-20 fest miteinander verbunden (Schweißverbindung).
Die Flachstäbe bzw. Zwischenstücke 18-20 sind etwas länger als der Abstand
zwischen den paarweise benachbarten Obergurten 8-10 der Gitterträger 5-7 und 15-17.
Die Anzahl und Länge der Flachstäbe bzw. Zwischenstücke 18-20 hängt insbesondere
von der speziellen Geometrie der Fertigdeckenelemente 2, 3 und ihrer Gitterträger
5-7 und 15-17 sowie den besonderen mechanischen Anforderungen an
diese bzw. an das mit diesen zu errichtende Fundament ab.Upended in the aforementioned manner and arranged in mirror image to each other
are the two finished
Die Betonplatte 4 des rechten Fertigdeckenelementes 3 und die Betonplatte 21 des
linken Fertigdeckenelementes 2 befinden sich in einem parallelen Abstand voneinander
und bilden gleichsam die Schaluhgswände des Stahlbetonteils 1. Das Stahlbetonteil
1 steht auf der unteren Längskante 14 der Betonplatte 4 des rechten Fertigdeckenelementes
3 und der unteren Längskante 22 der Betonplatte 21 des linken
Fertigdeckenelementes 2. In diesem Zustand werden Stahlbetonteile wie das Stahlbetonteil
1 nach einem bestimmten Verlegeplan auf der Baustelle aufgestellt. Von
oben werden diese dann mit Ortbeton befüllt, der somit den gesamten freien Raum
zwischen den Betonplatten 4 und 21 einnimmt. Die Gitterträger 5-7 und 15-17 gewährleisten
zusammen mit den Betonplatten 4 und 21 sowie dem Ortbeton die erforderliche
mechanische Festigkeit bzw. Stabilität des Stahlbetonteils 1 und des mit
diesem errichteten Gebäudefundamentes.The
Ein Ausschnitt eines solchen Fundamentes geht aus Fig. 4 hervor. An einer Stelle ist
dort das Stahlbetonteil 1 vorgesehen. An jedes offene seitliche Ende des Stahlbetonteils
1 schließt sich das nächste Stahlbetonteil an, zum Beispiel das Stahlbetonteil
23, das im Prinzip genauso ausgebildet und angeordnet ist wie das Stahlbetonteil 1.
Die Betonplatten 24 und 25 des Stahlbetonteils 23 sind gleich dick wie die Betonplatten
4 und 21 des Stahlbetonteils 1 und haben den gleichen parallelen Abstand
voneinander. Die auf Stoß und auf ihren unteren Längskanten 14, 22 stehenden
Stahlbetonteile 1 und 23 schließen daher bündig aneinander an und bilden gewissermaßen
einen mit Ortbeton befüllbaren Fundamentkanal. Wenn die für ein Fundament
vorgesehenen Stahlbetonteile eine geschlossene ringförmige Anordnung
aufweisen, kann ohne weitere Maßnahmen sofort betoniert werden. Wenn ein Stahlbetonteil
- zum Beispiel das Stahlbetonteil 26 - ein freies Ende hat, an das sich kein
weiteres Stahlbetonteil anschließt, ist an dem offenen seitlichen Ende eine Schalungswand
vorzusehen. A section of such a foundation is shown in FIG. 4. At one point is
