Abstract

The part of the building has at least two fields (4) at an angle to each other and joined by a reinforced concrete corner-piece (8). A flat reinforcement (5) encloses the fields and the corner piece. The fields are concreted on one plane leaving the subsequent corner piece. When the concrete on the fields has set, the reinforcement left exposed between the fields is bent until the fields are at the required angle to each other. The cavities between the fields are filled with concrete before or after the bending to make the corners of the part of the building.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Bauteils aus Stahlbeton nach dem Oberbegriff des Anspruches 1 und eine Schalung zur Durchführung des Verfahrens.The invention relates to a method for producing a component from reinforced concrete the preamble of claim 1 and a formwork for performing the method.

Büro- und Hochhäuser werden vorwiegend in Stützenkonstruktion aus Stahlbeton hergestellt. Ein wesentlicher Aufwand entsteht dabei für die Schalungsarbeiten einschließlich der notwendigen Abstützungen und Aussteifungen. Dies betrifft die Decken und die Unterzüge sowie die Stützen. Das Ein- und Ausschalen wiederholt sich hierbei von Stockwerk zu Stockwerk.Office and high-rise buildings are predominantly made of reinforced concrete column construction produced. A considerable amount of effort is involved in the formwork work including the necessary supports and bracing. This affects the Blankets and beams and supports. Forming and stripping is repeated here from floor to floor.

Damit die Schalungsarbeiten bei Decken entfallen können, ist die Verwendung von Filigrangroßflächendeckenplatten bekannt, die im Betonwerk vorfabriziert werden. Diese werden am Bau mit Ortbeton zu einer tragenden Einheit vergossen. Um die Schalungsarbeiten bei Wänden zu vermeiden, ist die Verwendung von vorgefertigten Doppelwandelementen bekannt, die gegebenenfalls nach Einbringen einer Bewehrung mit Ortbeton ausgegossen werden.So that the formwork work on ceilings can be omitted, the use of Filigree large-scale ceiling slabs are known, which are prefabricated in the concrete plant. This are cast on site with in-situ concrete to form a load-bearing unit. To the To avoid formwork work on walls, the use of prefabricated Double wall elements are known, which if necessary after inserting a reinforcement Poured in-situ concrete.

Dagegen werden Stützen und Unterzüge in konventioneller Bauweise hergestellt. Dies bedingt jedoch die erheblichen, eingangs erwähnten Schalungsarbeiten. Hinzu kommt, daß die Schalungen der Form der Stützen und Unterzüge nicht variabel anpaßbar sind, so daß zusätzlich relativ hohe Schalungskosten entstehen, wenn Stützen oder Unterzüge unterschiedlicher Form gefertigt werden sollen.In contrast, supports and beams are manufactured in a conventional manner. This however, causes the considerable formwork work mentioned at the beginning. Come in addition, that the formwork of the shape of the supports and beams are not variably adjustable, so that in addition relatively high formwork costs arise when supports or beams different shape to be manufactured.

Es besteht die Aufgabe, das Verfahren so auszubilden, daß Schalungsarbeiten am Bau entfallen können. There is the task of training the method so that formwork work on the construction can be omitted.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen des Verfahrens und eine Schalung sind den Unteransprüchen entnehmbar.This problem is solved with the features of claim 1. Advantageous Refinements of the method and formwork are the subclaims removable.

Ausführungsbeispiele werden nachfolgend an Hand der Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 bis 4 schematisch aufeinanderfolgende Verfahrensschritte;
  • Fig. 5 die Darstellung eines Biegeschritts;
  • Fig. 6 einen Schnitt durch eine nach dem Verfahren hergestellte Stütze; und
  • Fig. 7 einen Schnitt durch einen nach dem Verfahren hergestellten Unterzug.
    • Exemplary embodiments are explained in more detail below with reference to the drawings. Show it:
  • 1 to 4 schematically successive process steps;
  • 5 shows the representation of a bending step;
  • 6 shows a section through a support produced by the method; and
  • Fig. 7 shows a section through a beam made by the method.

    • Auf einer ebenen Schalungsfläche 1 wird ein Schalungsteils aufgesetzt, das aus einem im Querschnitt im wesentlichen T-förmigen Unterteil 2 und einem im Querschnitt im wesentlichen rechteckigen Oberteil 3 besteht. Das obere Ende des mittleres Schenkels des T-förmigen Unterteils 2 greift hierbei in eine längs verlaufende Nut an der Unterseite des Oberteils 3 ein. Beidseits dieses Schalungsteils schließen sich die später herzustellenden Felder 4 an. Durch vertikale Schlitze am unteren Schalungsteil 2, die sich bis zur Spitze des unteren Schalungsteils 2 erstrecken, verlaufen Bewehrungsstäbe 5 durch die sich beidseits anschließenden Felder 4.On a flat formwork surface 1, a formwork part is placed, which consists of a Cross section substantially T-shaped lower part 2 and a cross section in essential rectangular top 3 there. The upper end of the middle leg of the T-shaped lower part 2 engages in a longitudinal groove on the underside of the upper part 3 a. They close later on both sides of this formwork part fields 4 to be produced. Through vertical slots on the lower formwork part 2, the Reinforcing bars 5 extend to the top of the lower formwork part 2 through the fields 4.

    Die Felder 4 werden mit Beton vergossen. Nach dem Aushärten des Betons und dem Entschalen entsteht ein Bauteil gemäß Figur 2. Hierbei sind die Felder 4 im Abstand zueinander angeordnet, jedoch über die Bewehrungsstäbe 5 an ihren einander benachbarten Rändern miteinander verbunden. Zwischen den Feldern 4 ist somit eine Aussparung vorhanden, welche in ihrem unteren Teil T-förmig und ihrem oberen Teil U-förmig ausgebildet ist. Diese Querschnittsform der Aussparung entspricht der Querschnittsform eines späteren Eckstücks 8, die sich ergibt, wenn die Felder 4 in eine Ebene geklappt sind.The fields 4 are poured with concrete. After the concrete has hardened and the A component according to FIG. 2 is removed from the mold. The fields 4 are spaced apart arranged to each other, but via the reinforcing bars 5 on their each other adjacent edges joined together. There is thus a between the fields 4 Recess available, which is T-shaped in its lower part and U-shaped in its upper part is trained. This cross-sectional shape of the recess corresponds to that Cross-sectional shape of a later corner piece 8, which results when the fields 4 in a Level are folded.

    Die beiden Felder 4 werden nunmehr V-förmig gegeneinander geschwenkt, wobei die die Felder 4 verbindenden Bewehrungsstäbe 5 V-förmig gebogen werden. Das Biegen erfolgt in der Weise, daß der untere Teil der Aussparung seine Querschnittsfläche vergrößert, während der obere Teil der Aussparung seine Querschnittsfläche vermindert. Die benachbarten inneren Oberkanten 4A verlaufen im Abstand zueinander.The two fields 4 are now pivoted V-shaped against each other, the die Fields 4 connecting reinforcing bars 5 are bent into a V-shape. The bending takes place in such a way that the lower part of the recess has its cross-sectional area increases, while the upper part of the recess reduces its cross-sectional area. The adjacent inner upper edges 4A are spaced apart.

    Unter Verwendung einer Hilfsschalung, welche innen und außen die Ränder der benachbarten Felder 4 überbrückt, wird nunmehr zur Bildung eines Eckstücks 8 die Aussparung zwischen den Platten 4 mit Beton ausgefüllt. Es entsteht dann eine Eckverbindung zwischen den winkelig zueinander verlaufenden Feldern 4 gemäß Figur 4.Using an auxiliary formwork, which the edges of the inside and outside bridging adjacent fields 4, is now to form a corner piece 8 Gap between the plates 4 filled with concrete. Then one arises Corner connection between the angularly extending fields 4 according to FIG. 4.

    Anstelle einer inneren Hilfsschalung kann innenseitig ein Winkelstück 7 vorgesehen werden, das mit Anschweißplatten 6 verschweißt ist, die innenseitig am Rand der Felder 4 eingelassen sind. Diese Anschweißplatten 6 sind mit weiteren Bewehrungsstäben der Felder 4 verbunden, die jedoch nicht benachbarte Felder 4 miteinander verbinden, sondern am Rand eines jeden Felds 4 enden. Sie können jedoch über den Rand überstehen und werden dann mit den überstehenden Enden in den Beton des Eckstücks 8 eingebunden, wie dies die Figur 4 in ihrem rechten Teil verdeutlicht. Sind die Winkelstücke 7 nur abschnittsweise vorhanden, kann zusätzlich eine Hilfsschalung erforderlich sein.Instead of an inner auxiliary formwork, an angle piece 7 can be provided on the inside are, which is welded to welding plates 6, the inside on the edge of the fields 4 are embedded. These welding plates 6 are with additional reinforcement bars Fields 4 connected, but which do not connect adjacent fields 4 with each other, but end at the edge of each field 4. However, you can over the edge protrude and are then with the protruding ends in the concrete of the corner piece 8th involved, as shown in Figure 4 in its right part. Are the Angle pieces 7 only available in sections, can also be an auxiliary formwork to be required.

    Das Betonieren des Eckstücks 8 kann auch durchgeführt werden, bevor der Biegevorgang stattindet, jedoch muß sichergestellt sein, daß das Biegen erfolgt, bevor der Beton des Eckstücks 8 ausgehärtet ist. Die dabei verwendete äußere Eckschalung 11 wird während des Biegevorgangs in Pfeilrichtung in Richtung der Felder 4 verschoben. Überschüssiger Beton kann zwischen den inneren Oberkanten 4A austreten. Die Ausgangslage dieses Betoniervorgangs ist in Figur 3 gestrichelt dargestellt. Die Endlage der äußeren Eckschalung ist in Figur 3 mit 11A verdeutlich.The concreting of the corner piece 8 can also be carried out before the Bending process takes place, but it must be ensured that the bending takes place before the concrete of the corner piece 8 has hardened. The outer corner formwork 11 used here is moved in the direction of the arrow in the direction of the fields 4 during the bending process. Excess concrete can escape between the inner top edges 4A. The The starting position of this concreting process is shown in dashed lines in FIG. The end position the outer corner formwork is shown in Figure 3 with 11A.

    Die Figur 5 verdeutlicht den Biegevorgang bei zwei nach dem Biegen rechtwinklig zueinander stehenden Feldern 4. Gegen die Felder 4 liegt jeweils eine Biegerolle 9 an. An der den Biegerollen 9 gegenüberliegenden Seite liegt gegen die Bewehrungsstäbe 5 der Mittelschenkel eines T-förmigen Widerlagers 10 an. Die Biegerollen 9 werden jeweils um 45° verschwenkt, wobei ihre Endlage mit 9A bezeichnet ist. Nach Beendigung des Biegevorgangs wird das Widerlager 10 aus dem Zwischenraum zwischen den Feldern 4 und die äußere Eckschalung 11 gegen die Felder 4 verfahren, wonach dann das Eckstück 8 betoniert wird. Anstelle beide Felder 4 zu schwenken, ist es auch möglich, eines der Felder 4 um 90° zu schwenken. Es können auch mehrere, längs der Felder 4 verteilte Biegerollen 9 vorgesehen sein. Das Widerlager 10 kann entfallen, wenn die Felder 4 beim Biegevorgang entsprechend fixiert sind.FIG. 5 illustrates the bending process in two at right angles after the bending mutually standing fields 4. A bending roller 9 lies against each of the fields 4. On the side opposite the bending rollers 9 lies against the reinforcing bars 5 of the Middle leg of a T-shaped abutment 10. The bending rollers 9 are each around Pivoted 45 °, its end position is designated 9A. After completing the Bending process becomes the abutment 10 from the space between the fields 4th and move the outer corner formwork 11 against the fields 4, after which the corner piece 8 is concreted. Instead of swiveling both fields 4, it is also possible to use one of the Swivel fields 4 by 90 °. There can also be several distributed along the fields 4 Bending rolls 9 may be provided. The abutment 10 can be omitted if the fields 4 at Bending process are fixed accordingly.

    Die Figur 6 zeigt eine nach dem Verfahren hergestellte hohle Stütze. Sie besteht aus den Feldern 4B, 4C, 4D und 4E. Diese Felder 4B bis 4E werden auf der Schalungsfläche 1 in einer Ebene liegend hergestellt. Die Bewehrungsstäbe 5 verlaufen durchgehend durch alle vier Felder. Bei den Feldern 4B und 4E stehen diese Bewehrungsstäbe am äußeren Rand über die Felder 4E und 4B über. Sodann wird in vorbeschriebener Weise das Eckstück 8B, sodann das Eckstück 8C und nunmehr das Eckstück 8D hergestellt. Am Ende des Biegeschritts zur Herstellung des Eckstücks 8D kommen die seitlich über die Felder 4B und 4E überstehenden Enden 5A der Bewehrungsstäbe 5 miteinander in Berührung und werden miteinander verschweißt, worauf dann das Eckstück 8E betoniert wird. Die überstehenden Enden 5A der Felder 4B und 4E sind längs der Kanten 4A versetzt zueinander angeordnet, damit sie nebeneinander zu liegen kommen.Figure 6 shows a hollow support made by the method. It consists of the Fields 4B, 4C, 4D and 4E. These fields 4B to 4E are on the formwork surface 1 in manufactured on one level. The reinforcement bars 5 run continuously all four fields. In fields 4B and 4E, these reinforcement bars are on the outside Edge over fields 4E and 4B over. Then in the manner described above Corner piece 8B, then the corner piece 8C and now the corner piece 8D. At the At the end of the bending step for producing the corner piece 8D, they come laterally over the Fields 4B and 4E projecting ends 5A of the reinforcing bars 5 with each other Touch and are welded together, whereupon the corner piece 8E is concreted becomes. The protruding ends 5A of the panels 4B and 4E are along the edges 4A staggered so that they come to lie side by side.

    Der aus drei Feldern 4B, 4C und 4D bestehende Unterzug wird in vorbeschriebener Weise hergestellt, wobei zwei Biegevorgänge zur Herstellung der Eckstücke 8B und 8C erforderlich sind. The beam consisting of three fields 4B, 4C and 4D is described above Manufactured way, with two bending operations to produce the corner pieces 8B and 8C required are.

    Mit dem Verfahren sind anstelle von Stützen und Unterzügen auch andere Bauteile herstellbar, bei denen die Felder 4 winkelig zueinander verlaufen.The method also uses other components instead of supports and beams producible in which the fields 4 run at an angle to each other.

    An der Baustelle können den statischen Erfordernissen entsprechend die Stützen und Unterzüge mit einer Bewehrung versehen und mit Ortbeton verfüllt werden, wobei die Felder 4 und die Eckstücke 8 als verlorene Schalung dienen.At the construction site, the supports and Provide beams with reinforcement and fill them with in-situ concrete, the Fields 4 and the corner pieces 8 serve as lost formwork.
