Abstract

A beam support joint for a column and a beam, which are each constructed from concrete and at least one metal section having a pair of flanges joined by a web and forming at least one recess of the metal section which is filled with concrete and the outer surfaces of the flanges of the metal section are not covered with concrete and are otherwise free. An upper support strap is mounted on an upper flange of the beam, and is attached to the column and the beam. The upper support strap and the webs of both the beam and the column all lie substantially in the same plane. On a flange of the column a lower support plate is advantageously welded which has a width corresponding approximately to the flange of the column. This lower support plate has at least one recess on its upper side which suitably engages at leat one projection provided on a lower flange of the beam. Alternatively the lower support plate can be dispensed with and the upper support strap can be mounted on a cover plate provided on the column with at least one tight fitting screw.

Description

Die Erfindung betrifft einen Riegel-Stützenanschluss für Stützen und Riegel welche aus Beton und wenigstens einem Profil gebildet sind, wobei die offenen Kammern des Profils grösstenteils mit Beton ausgefüllt sind und die Aussenflächen der Flansche freiliegen d.h. nicht mit Beton bedeckt sind.The invention relates to a transom-column connection for supports and transoms which are formed from concrete and at least one profile, the open chambers of the profile being largely filled with concrete and the outer surfaces of the flanges being exposed, i.e. are not covered with concrete.

Eine derartige Stütze, welche auf den Flanschaussenseiten, d.h. ausserhalb der Profilumrisslinien keinen Beton aufweist ist bspw. in der DE-OS 28 29 864 beschrieben. Der Kammerbeton wird durch auf die Innenstegseiten des Stahlprofils aufgeschweisste Verbundmittel kraftschlüssig mit diesem verbunden, um sowohl bei Raumtemperatur als auch bei Brandtemperatur ein Loslösen des Kammerbetons zu vermeiden. Stahlprofilquerschnitt, Betonquerschnitt und Bewehrungsstahlquerschnitt tragen entsprechend ihrer Flächenanteile und ihrer temperaturabhängigen Festigkeiten anteilig mit. Im Brandfall erfolgt mit dem Temperaturanstieg eine fortwährende Lastumlagerung vom Stahlprofilquerschnitt auf den Stahlbetonquerschnitt vor allem bedingt durch die Entfestigung der Flansche, die den grässten Teil des Stahlprofils ausmachen.Such a support, which on the flange outsides, i.e. has no concrete outside the profile contour lines is described, for example, in DE-OS 28 29 864. The chamber concrete is non-positively connected to the inside of the steel profile by means of welded composite materials, in order to avoid detachment of the chamber concrete both at room temperature and at fire temperature. Steel profile cross-section, concrete cross-section and reinforcement steel cross-section contribute proportionately according to their surface area and their temperature-dependent strength. In the event of a fire, the temperature rises and the load is continuously shifted from the steel section to the reinforced concrete section, primarily due to the softening of the flanges, which make up the largest part of the steel section.

Da die Bewehrung im Beton nicht optimal angeordnet ist, was die im Brandfall im Profil entstehende Temperaturverteilung anbelangt, hat die Anmelderin in der LU 84 772 vorgeschlagen in dem Beton wenigstens ein weiteres Profil anzuordnen, das mit dem Steg des Haupt-Profils verbunden ist, dessen Flanschenaussenseiten nicht mit einer Betonüberdeckung versehen sind. Da ein Teil der Profile aus denen dieses Verbundprofil besteht in thermisch geschützten Zonen angebracht ist, ist eine hohe Tragfähigkeit unter Brandbeanspruchung gewahrleistet. In der Patentanmeldung LU 84 966 hat die Anmelderin weiterhin ein derartiges Verbundprofil beschrieben bei dem in dem Beton wenigstens ein mit dem Steg des Profils verbundenes Flacheisen angeordnet ist.Since the reinforcement in the concrete is not optimally arranged with regard to the temperature distribution that arises in the case of a fire in the profile, the applicant in LU 84 772 proposed to arrange at least one further profile in the concrete that is connected to the web of the main profile, the Flange outsides are not covered with concrete. Since some of the profiles that make up this composite profile are located in thermally protected zones a high load-bearing capacity is guaranteed under fire. In patent application LU 84 966, the applicant has further described such a composite profile in which at least one flat iron connected to the web of the profile is arranged in the concrete.

Es ist bekannt Riegel-Anschlüsse an obige Träger mittels Blechen herzustellen wobei die Bleche mit den Trägerflanschen oder dem Trägersteg der Stütze verschweisst werden. Diese Massnahme kann werksseitig vorgenommen werden. Auf dem Bau müssen dann die Riegel über ihre Stege an diesen Blechen festgeschweisst oder geschraubt werden. Anschliessend werden die für die Montagearbeiten benötigten Hohlräume ausbetoniert. Diese Anschlüsse sind Arbeitsintensiv und setzen ein abschliessendes Ausbetonieren voraus, welches wegen der gewünschten Feuerklasse unumgänglich ist.It is known to produce bolt connections to the above supports by means of metal sheets, the metal sheets being welded to the support flanges or the support web of the support. This can be done at the factory. During construction, the bars must then be welded or screwed to these sheets via their webs. The cavities required for the assembly work are then concreted. These connections are labor-intensive and require a final concreting, which is inevitable because of the desired fire class.

Es ist weiterhin bekannt eine Verbindung Stütze-Riegel über Knaggen herbeizuführen. Die Knaggen können am Flansch der Stütze befestigt werden. Es besteht aber auch die Möglichkeit ein Blech an die zwei gegenüberliegenden Flanschseiten festzuschweissen und die Knagge an diesem Blech zu befestigen. Die untere Flanschseite des Riegels wird auf dem Bau auf die Knagge aufgelegt'(und eventuell verschweisst) während die beiden Enden des oberen Flansches mit an dem Stützen- Flansch verschweisst werden können. In einer anderen Ausführungsform, dem sogenannten Kopfplattenknaggenanschluss, wird das Riegelende mit einer Kopfplatte versehen. Der untere Flansch (sowie eine Seite der Kopfplatte) kommt auf die Knagge zu liegen, während in Nähe des oberen Riegel-Flansches die Kopfplatte mit dem Stützen- Flansch verschraubt wird. Hierzu können Längs- und Querlöcher im Flansch beziehungsweise in der Kopfplatte vorgesehen sein. Die für die Verschraubungsarbeiten benötigten Hohlräume werden auch hier nachträglich ausbetoniert.It is also known to bring about a connection between the column and the latch via lugs. The lugs can be attached to the flange of the support. But there is also the option of welding a sheet metal to the two opposite flange sides and attaching the lug to this sheet metal. The lower flange side of the transom is placed on the bracket on the structure (and possibly welded), while the two ends of the upper flange can also be welded to the support flange. In another embodiment, the so-called head plate lug connection, the bolt end is provided with a head plate. The lower flange (as well as one side of the head plate) comes to rest on the collar, while the head plate is screwed to the support flange in the vicinity of the upper transom flange. For this purpose, longitudinal and transverse holes can be provided in the flange or in the head plate. The cavities required for the screwing work are also subsequently concreted.

Es ist Aufgabe der vorliegenden Erfindung, die bauseitigen Riegel-Stützen Verbindungs-Arbeiten zu reduzieren und einen Anschluss vorzuschlagen der im Werk grösstenteil vorgefertigt wird und es erlaubt auf dem Bau die definitive relative Lage Stütze-Riegel durch einfaches Einschieben festzulegen.It is an object of the present invention to reduce the on-site transom supports connecting work and to propose a connection which is largely prefabricated in the factory and allows the definitive relative position of the transom to transom on the building fixed insertion.

Diese Aufgabe wird dadurch gelöst, dass am oberen Flansch des Riegels ein Zuglasche angeordnet ist und derart mit der Stütze und dem Riegel verbunden ist, dass Zuglasche, Riegel- und Stützen-Steg sich im wesentlichen in derselben Ebene befinden und, dass am Stützenflansch eine Auflegeplatte festgeschweisst ist, welche eine Breite besitzt, die etwa der Breite des Stüzenflanschs, auf dem sie festgeschweisst ist, entspricht. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen wiedergegeben.This object is achieved in that a pull tab is arranged on the upper flange of the ledger and is connected to the support and the ledger in such a way that the pull tab, ledge and prop web are located essentially in the same plane and that a support plate is located on the prop flange is welded, which has a width which corresponds approximately to the width of the support flange on which it is welded. Advantageous embodiments of the invention are given in the subclaims.

Die Vorteile der Erfindung bestehen darin, dass die auf der Baustelle eventuell anzubringende Schweissnaht zwischen Zuglasche und Stützenflansch ausserhalb des Riegels liegt und somit solange sichtbar bleibt, bis dass die Decke ausbetoniert ist. Weiterhin ist der Momentverlauf im Riegel günstig und wird bis zu 50X abgebaut und auf die Stütze übertragen; nennenswert kleinere Abmessungen des Riegels sind folglich möglich. Durch die erzielte Rahmenwirkung können seitliche (horizontale) Kräfte aufgefangen werden und es besteht die Möglichkeit auf andere Stabilisierungselemente, wie Fachwerk oder Stahlbetonkern, zu verzichten. In warmen Zustand ist ein wesentlicher Vorteil darin zu sehen, dass bei negativem Rahmeneckenmoment der Zugbereich über dem geschützten Riegelflansch im Beton der Decke eingebettet ist. Zusätzlich bietet sich erfindungsgedäss ein vollständiger provisorischer Zusammenbau des Stahlskeletts an; die eventuell erforderlichen Schweissnähte können in einer zweiten Phase durchgeführt werden.The advantages of the invention consist in the fact that the weld seam that may have to be made on the construction site between the pull tab and the support flange lies outside the transom and thus remains visible until the ceiling is concreted. Furthermore, the moment curve in the bolt is favorable and is reduced up to 50X and transferred to the support; Significantly smaller dimensions of the bar are therefore possible. The achieved frame effect allows lateral (horizontal) forces to be absorbed and there is the option of dispensing with other stabilizing elements such as truss or reinforced concrete core. A warm advantage is to be seen in the fact that the tension area is embedded in the concrete of the ceiling above the protected transom flange when the frame corner moment is negative. In addition, d AESS a complete provisional assembly of the steel skeleton offers erfindungsge; the welding seams that may be required can be carried out in a second phase.

Die Erfindung wird im folgenden anhand von zwei Ausführungsbeispielen näher erläutert. Es zeigen:

  • - die Figur 1, eine Seitenansicht auf einen Riegel und eine Stütze, welche mit dem erfindungsgemässen Anschluss versehen sind,
  • - die Figuren 2 und 3, Schnitte längs den Linien II-II und III-III auf Figur 1,
  • - die Figur 4, eine vergrösserte Darstellung des Anschlusses,

The invention is explained in more detail below using two exemplary embodiments. Show it:
  • 1 shows a side view of a latch and a support which are provided with the connection according to the invention,
  • FIGS. 2 and 3, sections along lines II-II and III-III in FIG. 1,
  • 4 shows an enlarged view of the connection,
  • - Figure 5, a variant of the connection according to the invention.

Auf Figur 1 ist eine Stütze 1 dargestellt an die ein Riegel 2 angeschlossen ist. Der Riegel und die Stütze wurden gemäss den in der DE-PS 28 29 864 beschriebenen Massnahmen hergestellt und bestehen im wesentlichen aus einem Stahlprofil 3, Kammerbeton 4 und Bewehrungsstahl 5, wobei der Bewehrungsstahl am Steg 6 des Stahlprofils 3 befestigt ist (Siehe Figur 2). Um den Verbund Träger-Kammerbeton zu gewahrleisten wurden Dübel 7 am Trägersteg 6 angeschweisst. Die Haftung des Deckenbetons 8 wird durch am oberen Flansch des Riegels 2 angeordneten Dübeln 9 gewährleistet. Weiterhin ist auf Figur 1 die den Riegel-Stützenanschluss herbeiführende Zuglasche 10 sowie die Auflegeplatte 11 zu sehen.In Figure 1, a support 1 is shown to which a latch 2 is connected. The bolt and the support were produced in accordance with the measures described in DE-PS 28 29 864 and essentially consist of a steel profile 3, chamber concrete 4 and reinforcing steel 5, the reinforcing steel being fastened to the web 6 of the steel profile 3 (see FIG. 2) . To ensure the bond between the beam and the concrete, dowels 7 were welded to the beam 6. The adhesion of the ceiling concrete 8 is ensured by dowels 9 arranged on the upper flange of the bar 2. Furthermore, the pull tab 10 which brings about the transom-support connection and the support plate 11 can be seen in FIG.

Wie auf Figur 3 dargestellt hat die Auflegeplatte 11 etwa die Breite des Stützenflansches und ist mit zwei Löchern 12 zur Aufnahme der Montagebolzen 13 versehen (siehe Figur 4). Diese Löcher 12 mit den korrespondierenden Montagebolzen 13 sind nicht unabkömmlich, erlauben aber einen provisorischen Zusammenbau des Stahlskeletts. Die Schweissarbeiten können dabei zu einem späteren Zeitpunkt vorgenommen werden. Um einen bequemen Zusammenbau zu erzielen, liegen die Abmessungen der Bolzen 13 geringfügig unter denen der Löcher 12. Anstatt der Bolzen kann man auch irgendwelche andere Hilfsmittel vorsehen (bspw. pyramidenartige Stahlvorsprünge) welche die provisorische relative Lage der Riegel und Stützen festlegen. Zu beachten ist lediglich, dass die feste Lage des Riegelendes 14 auf dem Stützen- Flansch nicht beeinträchtigt wird. Andernfalls ist bei negativem Rahmeneckenmoment der direkte Fluss der Druckkräfte vom Riegelbeton in die Stütze nicht gegeben.As shown in Figure 3, the support plate 11 has approximately the width of the support flange and is provided with two holes 12 for receiving the mounting bolts 13 (see Figure 4). These holes 12 with the corresponding mounting bolts 13 are not indispensable, but allow a provisional assembly of the steel skeleton. The welding work can be carried out at a later time. In order to achieve a convenient assembly, the dimensions of the bolts 13 are slightly below those of the holes 12. Instead of the bolts, one can also provide any other means (for example pyramid-like steel projections) which determine the provisional relative position of the bolts and supports. It should only be noted that the fixed position of the bolt end 14 on the support flange is not impaired. Otherwise, the direct flow of the compressive forces from the transom concrete into the column is not given if the frame corner moment is negative.

Die Auflegeplatte . 11 ist ringsum mittels einer Kehlnaht an die Stütze 1 angeschweisst, ausser an der oberen Seite, wo die Platte angeschrägt wurde und sich eine stärkere versenkte Schweissnaht 15 befindet. Die versenkte Naht erlaubt ein sattes Aufliegen des Riegels 2 und somit einen ausgeglichenen Fluss der Querkräfte vom Riegel auf die Auflegeplatte. Weil diese versenkte Naht 15 vor der direkten Hitzestrahlung geschützt liegt, ist dies die Schweissnaht welche in Wirklichkeit der Auflegeplatte 11 längere Zeit erlaubt in warmem Zustand Querkräfte vom Riegel 2 zur Stütze 1 zu übertragen. Somit kann der Feuerwiderstand der ungeschützten Auflegeplatte 11 mindestens 90 Minuten erreichen.The platter. 11 is welded all around to the support 1 by means of a fillet weld, except on the upper side, where the plate has been chamfered and there is a stronger sunken weld seam 15. The countersunk seam allows the bar 2 to lie flat and thus a balanced flow of the transverse forces from the bar to the support plate. Because this countersunk seam 15 is protected from direct heat radiation, this is the weld seam which in reality allows the support plate 11 to transmit transverse forces from the bar 2 to the support 1 in the warm state for a longer time. The fire resistance of the unprotected support plate 11 can thus reach at least 90 minutes.

Die Zuglasche 10 wird vorteilhafterweise werksseitig auf den Riegelflansch festgeschweisst (Bezugszeichen 16). Die Lasche sollte dabei in Riegelsteg-Ebene liegen. Die Montage-Schweissnaht 17 wird zu einem späteren Zeitpunkt vorgenommen. Um einen optimalen Kräftefluss zu erzielen ist dieser Teil der Zuglasche angespitzt und wird somit über eine K-Schweissnaht mit der Stütze verbunden. Die Montagebolzen 13 sowie die Locher 12 sind dabei gemäss einer bevorzugten Ausführungsform der Erfindung derart angeordnet, dass die Lasche ebenfalls in die Ebene des Stützensteges zu liegen kommt.The pull tab 10 is advantageously welded to the locking flange in the factory (reference number 16). The tab should be in the level of the crossbar. The assembly weld seam 17 is carried out at a later time. In order to achieve an optimal flow of forces, this part of the pull tab is sharpened and is therefore connected to the support via a K-weld seam. The mounting bolts 13 and the holes 12 are arranged according to a preferred embodiment of the invention such that the tab also comes to lie in the plane of the support web.

Eine weitere Ausgestaltung eines Riegel-Stützenanschlusses ist auf Figur 5 dargestellt. Hier werden der Riegel 2 sowie die Zuglasche 10 werksseitig mit einer Kopfplatte 50 versehen. Der untere Flansch des Riegels 2 sowie die Kopfplattenunterseite kommen satt auf die Auflegeplatte 11 zu liegen während beidseitig von der Zuglasche 10 die Kopfplatte 50 mit dem Stützenflansch verschraubt wird (Bezugszeichen 52). Da die Verschraubungsarbeiten sofort bei jeder Witterung vorgenommen werden können, sind in dieser Ausführungsform die Aussparungen 12 / Vorsprünge 13 abkümmlich. Zu bemerken ist noch, dass hier der Verbund Stahlprofil-Kammerbeton über an den Stegen festgeschweisste Bügel 51 sichergestellt wird.Another embodiment of a transom support connection is shown in FIG. 5. Here the bolt 2 and the pull tab 10 are provided with a head plate 50 at the factory. The lower flange of the bolt 2 and the underside of the head plate come to lie snugly on the support plate 11 while the head plate 50 is screwed to the support flange on both sides of the pull tab 10 (reference number 52). Since the screwing work can be carried out immediately in any weather, in this embodiment the recesses 12 / projections 13 are inconsistent. It should also be noted that the composite steel profile-chamber concrete is secured here by brackets 51 welded to the webs.

Eine weitere Ausgestaltung des Anschlusses nach Fig. 5 sieht einen Wegfall der Auflegeplatte 11 vor. Hierzu ist ein genaues Aufbohren der Löcher für die Schrauben 52 notwendig, welche also als Passschrauben genutzt werden. In diesem Fall übernehmen diese Schrauben 52 zusätzlich die Funktion der Auflegeplatte 11, werden also auf Zug (kommend aus dem negativen Rahmenbiegemoment) sowie auf Querkraft beansprucht. Diese Doppelfunktion ist ohne weiteres tragbar, da ja besagte Schrauben im feuergeschützten Bereich des Deckenbetons liegen.A further embodiment of the connection according to FIG. 5 provides for the support plate 11 to be omitted. This requires an exact drilling of the holes for the screws 52, which are therefore used as fitting screws. In this case, these screws 52 also take on the function of the support plate 11, that is, they are subjected to tension (coming from the negative frame bending moment) and to shear force. This double function is easily portable, since the screws in question are located in the fire-protected area of the ceiling concrete.

Hervorzuheben ist, dass die Lasche nach Fertigstellung des Deckenbetons in einen feuergeschützten Bereich zu liegen kommt und infolgedessen, zusammen mit den durch Kammerbeton geschützten Stegen des Riegels 2 und der Stütze 1, einen regelmässigen Zugkräftefluss des negativen Rahmeneckenmomentes in warmem Zustand bestens gewährleistet. Die Lasche kann somit bei Brandfall ihre tragende Funktion weiter ausüben, wenn diejenige der Auflegeplatte stark nachgelassen hat, und so den Zusammenbruch der Konstruktion bis zu 180 Minuten hinauszögern.It should be emphasized that the flap comes to lie in a fire-protected area after completion of the ceiling concrete and consequently served, together with the bars of the transom 2 and the column 1 protected by chamber concrete, a regular flow of tensile forces of the negative frame corner moment in the warm state is optimally guaranteed. In the event of a fire, the tab can therefore continue to perform its load-bearing function if that of the support plate has weakened considerably, and so delay the collapse of the construction for up to 180 minutes.
