Abstract

The flexure girder incorporates buckle-resistant stabilised external surface reinforcements. Use is made of formwork units retained as a permanent element in the bend structure. The configuration of these determines the cross-sectional shape of the element. The interior space is filled with material which subsequently sets hard, with at least pressure-resistant and adhesive rigidity qualities. This takes over the role of buckle stabilisation of the external sheating and effects bonding outside the support areas without involving additional loop shackles. This enables high-quality girders to be produced by simple means, with external sheating performing multiple functions.

Description

Biegeträger mit beulstabilisierten Bending beam with dent stabilized

Außenflächenbewehrungen Zusatzanmeldung zu P 2? 26 413.7 und G 77 18 499.7 Die Erfindung betrifft die Herstellung von Biegeträgern als Verbundkonstruktionen mit dünnwandigen Schalelementen als Bewehrung und unter erzicht auf innere Bügelbewehrungen. External surface reinforcement Additional registration for P 2? 26 413.7 and G 77 18 499.7 The invention relates to the production of flexible beams as composite structures with thin-walled formwork elements as reinforcement and with internal stirrup reinforcements.

Der Zweck der Erfindung ist eshochleistungsfähige Biegeträger mit einfachen Arbeitsabläufen und ohne aufwendige i?ertigunseinrichtungen ausführen zu können.The purpose of the invention is to use high-performance bending beams carry out simple work processes and without complex calibration facilities to be able to.

Der Vorteil der Erfindung ist es daß die äußere Schalung mehrfache Funktionen übernehmen kann. Sie dient als Schalung der Formgebung der Elemente,ist die Schub-und Netzbewehrung und ersetzt einen Teil der Zugbewehrung und erhöht die Steifigkeit der Druckzone.The advantage of the invention is that the outer formwork is multiple Functions. It serves as formwork for the shaping of the elements the shear and mesh reinforcement and replaces part of the tensile reinforcement and increases the Stiffness of the pressure zone.

Der weitere Vorteil liegt darin begründet,daß die Außenschalung unterschiedlich aufgebaut sein kann,z.BO in Ampassung an die bauphysikalischen Eigenschaften,mehrschichtig sein kann und z.B, einen hohen Feuerwiderstand leistet. Statt einer Flächenschalung kann auch ein Maschennetz aus sich diagonal kreuzenden Stäben Verwendung finden.Ausser Stahl können NE-Metalle, glasfaserverstärkte Schalungen oder Verbundelemente Verwendung finden.The further advantage lies in the fact that the outer formwork is different can be built up, e.g. in adaptation to the physical properties of the building, multi-layered can be and, for example, provides a high level of fire resistance. Instead of surface formwork A mesh network of diagonally crossing bars can also be used Steel can use non-ferrous metals, glass fiber reinforced formwork or composite elements Find.

Das gleiche gilt für den nachträglich erhärtenden und nach der Erhärtung mindest druckfesten Mörtel der inneren Füllung.The same applies to the subsequent hardening and after hardening at least pressure-resistant mortar for the inner filling.

Er kann in seinen Eigenschaften variiert wenden und ist statischen und bauphysikalischen Forderungen anzupassen.Its properties vary and it is static and to adapt to building physics requirements.

Es ist die Aufgabe gestallt,ein leistungsfähiges Biegeelement mit in weiten Grenzen variierbaren statischen und bauphysikalischen Eigenschaften unter Verzicht auf umfangs reiche Fertigungsanlagen herstellen zu können.It is the task of using a powerful flexure static and structural properties that can be varied within wide limits To be able to do without extensive production facilities.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, daß Schalungen aus funktional geeigneten Materialien verwendet werden, die bleibendes Element des Biegeträgers sind und die jeweils geforderten statischen und bauphysikalischen Eigenschaften besitzen. Die Schalungen bilden einen profilierten Innenrauw,der mit einem nachträglich erhärtenden und nach der Erhärtung mindestens druckfesten Material gefüllt wird,das ausreichende Hafteigenschaften besitzt,Verbundkräfte zur Beulstabilisierung der äusseren dünnwandigen Schalungen zu entwickeln , sowie zur Übertragung der Verbundkräfte eingelegte Bewehrungen.The object is achieved according to the invention in that formwork Functionally suitable materials are used as the permanent element of the bending beam and the required static and structural properties own. The formwork forms a profiled interior roughness, which is subsequently followed by a hardening and after hardening at least pressure-resistant material is filled, the Has sufficient adhesive properties, bond forces to stabilize the buckling to develop external thin-walled formwork, as well as to transfer the composite forces inserted reinforcements.

Die Fig.1 erläutert als Ausführungsbeispiel einen Profil träger.AEs Außenschalung werden Feinbleche (1) verwendet.The Fig.1 explains as an embodiment a profile träger.AEs Thin sheets (1) are used for the outer formwork.

Der Innenraum wird mit einem weitgehend schwind-und kriecharmen Mörtel gefüllt, der die erforderlichen Hafteigenschaften besitzt,unter Beanspruchungen die Verbundwirkung mit den Schalblechen zu gewährleisten und den Verbund mit den eingelegten Zusatzbewehrungen so herstellt,daß im Regelfall auf zusätzliche Bügelbewehrungen verzichtet erden kann,da die Abstände der einzelnen Teile des Verbundelementes so gewählt sind, daß die statische Gesamtwirkung nicht beeinträchtigt wird.The interior is covered with a largely non-shrinking and creep-resistant mortar filled, which has the necessary adhesive properties, under stress to ensure the bond effect with the shuttering sheets and the bond with the inserted additional reinforcements in such a way that, as a rule, additional stirrup reinforcements can be dispensed with, since the distances between the individual parts of the composite element are so are chosen so that the overall static effect is not impaired.

Als Mörtel werden vorzugsweise schwind-und kriecharme Mörtel verwendet'die vorzugsweise hohe Dxuck-und Schubfestigkeiten entwickeln.Low-shrinkage and creep-resistant mortars are preferably used as the mortar preferably develop high pressure and shear strengths.

Die Außenfläche kann auch in Diagonalen aufgelöst werden(2), oder bauphysikalisc-h geforderte Beschichtungen (3) erhalten. Die Figur zeigt beispielsweise und schematisch das Wesen der Erfindung: Fig. 1. Querschnitt eines Verbundprofilträgers.The outer surface can also be broken down into diagonals (2), or Obtain physically required coatings (3). The figure shows, for example and schematically, the essence of the invention: Fig. 1. Cross section a composite profile beam.
