Description

Die Erfindung betrifft einen Stützenschuh für Betonstützen, Betonpfeiler oder dergleichen mit den Merkmalen nach dem Oberbegriff des Anspruchs 1.The invention relates to a column shoe for concrete columns, concrete pillars or the like with the features according to the preamble of claim 1.

Derartige Stützenschuhe werden beispielsweise im Hochbau zur Verschraubung von Fertigbetonteilen eingesetzt. Beispielsweise weisen entsprechende vorgearbeitete Betonpfeiler im Bereich ihrer Stirnenden eine Anzahl von Stützenschuhen auf, die mit an Seitenblechen des Stützenschuhes festgelegten Armierungsstäben fest im Betonbauteil eingegossen sind. Eine Grundplatte und an seitlichen Kanten der Grundplatte rechtwinklig dazu angeordnete Seitenbleche begrenzen einen Freiraum, der den Zugriff auf eine Verschraubung ermöglicht. Dazu weist die Grundplatte ein Schraubloch auf. Die Grundplatte mit dem Schraubloch liegt in der Ebene der Stirnfläche des Betonpfeilers. Der Betonpfeiler bzw. die Stütze kann mit einer Decke bzw. mit einem Fundament mit einbetonierten Bolzen verbunden werden. Auch können zwei aneinander angrenzende stirnseitige Grundplatten zweier stirnseitig miteinander zu verbindender Betonpfeiler mittels einer durch das Schraubloch hindurchgesteckten Schraube verbunden werden.Such support shoes are used, for example, in building construction for the screwing of precast concrete parts. For example, corresponding prefabricated concrete pillars in the region of their front ends on a number of column shoes, which are molded with fixed to side plates of the column shoe reinforcing bars firmly in the concrete component. A base plate and at the side edges of the base plate at right angles arranged side plates limit a space that allows access to a screw. For this purpose, the base plate on a screw hole. The base plate with the screw hole lies in the plane of the end face of the concrete pillar. The concrete pillar or the support can be connected to a ceiling or to a foundation with cast-in bolts. Also, two adjoining frontal base plates of two frontally to be joined concrete pillars can be connected by means of a screwed through the screw hole.

Für eine hohe Festigkeit müssen die Stützenschuhe sicher im Betonbauteil vergossen sein. Zur Herstellung der Verschraubung ist eine gute Zugänglichkeit des Freiraumes zwischen den Seitenblechen und der Grundplatte erforderlich, wobei auch ein Ausgleich von Maßtoleranzen ermöglicht sein muß. Des weiteren ist es erwünscht, den Stützenschuh mit einfachen Mitteln fertigen zu können.For high strength, the column shoes must be securely encapsulated in the concrete component. For the preparation of the screw connection, a good accessibility of the free space between the side plates and the base plate is required, whereby a compensation of dimensional tolerances must be made possible. Furthermore, it is desirable to be able to produce the support shoe with simple means.

Aus der DE 195 14 685 C2 ist ein als Pfahlschuh benannter Stützenschuh bekannt, bei dem eine Grundplatte einen im wesentlichen quadratischen Grundriß aufweist. Zwei Seitenbleche sind einteilig durch Abkanten eines Bleches in einem rechten Winkel gebildet, wobei das abgekantete Blech sich im rechten Winkel von der Grundplatte erhebt und dabei an zwei aufeinander zulaufenden Seitenkanten der quadratischen Grundplatte festgeschweißt ist. Zwei Armierungsstäbe sind an den innenseitigen, einander zugewandten Flächen des abgewinkelten Seitenbleches angeschweißt und erstrecken sich senkrecht zur Grundplatte. Die beiden Schenkel des L-förmig abgewinkelten Seitenbleches erstrecken sich etwa über die Hälfte der beiden Seitenkanten der Grundplatte, wobei die beiden Armierungsstäbe etwa im Bereich der freiliegenden Hochkanten des L-Profiles und demnach etwa mittig der Grundplattenseitenkanten angeordnet sind. Toleranzen beim Abkanten des Seitenbleches können zu Schwierigkeiten bei der Verschweißung mit der Grundplatte führen. Eine zuverlässige Verschweißung der Armierungsstäbe mit den beiden Schenkeln ist erschwert, da die Zugänglichkeit der in Richtung der Abkantung gelegenen Schweißnähte durch das Seitenblech behindert ist. Die innenseitig des L-Profiles gelegenen Armierungsstäbe liegen nahe am Schraubloch in der Grundplatte. Die Zugänglichkeit der Verschraubung ist ebenso wie ein Lagetoleranzausgleich zweier aneinander grenzender Schraublöcher gegeneinander erschwert.From DE 195 14 685 C2 a named as pile shoe column shoe is known in which a base plate has a substantially square outline. Two side plates are integrally formed by folding a sheet at a right angle, wherein the folded sheet rises at right angles to the base plate and is welded to two converging side edges of the square base plate. Two Armierungsstäbe are welded to the inside, facing surfaces of the angled side plate and extend perpendicular to the base plate. The two legs of the L-shaped angled side plate extend approximately over half of the two side edges of the base plate, wherein the two reinforcing rods are arranged approximately in the region of the exposed edges of the L-profile and therefore approximately centrally of the base plate side edges. Tolerances when folding the side plate can lead to difficulties in welding with the base plate. A reliable welding of the reinforcing bars with the two legs is difficult because the accessibility of the weld located in the direction of the fold is hindered by the side plate. The inside of the L-profile located reinforcing rods are close at the screw hole in the base plate. The accessibility of the screw is difficult as well as a position tolerance compensation of two adjacent screw holes against each other.

Der Erfindung liegt die Aufgabe zugrunde, einen Stützenschuh der eingangs erwähnten Gattung derart weiterzubilden, daß bei vereinfachtem Fertigungsaufwand eine leichte Montage der miteinander zu verbindenden Betonbauteile ermöglicht ist.The invention has the object of providing a support shoe of the type mentioned in such a way that with a simplified manufacturing effort easy mounting of the concrete components to be joined is made possible.

Die Aufgabe wird durch einen Stützenschuh mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a column shoe with the features of claim 1.

Dazu wird ein entsprechender Stützenschuh vorgeschlagen, bei dem die beiden seitlichen Kanten der Grundplatte mit den daran angeordneten Seitenblechen in einem spitzen Winkel zueinander angeordnet sind, wobei die beiden Seitenbleche als zueinander separate und mit der Grundplatte verbundene Bauteile ausgebildet sind. Als zweckmäßiger Winkel hat sich dabei ein spitzer Winkel im Bereich zwischen einschließlich 30° und einschließlich 75° und insbesondere von etwa 45° herausgestellt. Die zweiteilige Ausbildung der Seitenbleche erlaubt eine präzise Fertigung dieser Bleche aus einfachem Flachmaterial mit einfachen Mitteln. Der toleranzbehaftete Vorgang des Abkantens entfällt. Die lagegenaue Verschweißung mit der Grundplatte ist erheblich vereinfacht.For this purpose, a corresponding column shoe is proposed in which the two lateral edges of the base plate are arranged with the side plates arranged thereon at an acute angle to each other, wherein the two side plates are formed as mutually separate and connected to the base plate components. As an appropriate angle while an acute angle has been found in the range between 30 ° and including 75 ° and in particular of about 45 °. The two-part design of the side plates allows precise production of these sheets of plain flat material by simple means. The tolerance-related process of Abkantens deleted. The accurate welding with the base plate is considerably simplified.

Bei einer vorteilhaften Ausbildung der Grundplatte in Form eines unregelmäßigen Polygons ist die Variabilität der Anordnung relativ zur Querschnittsfläche der Betonstütze verbessert.In an advantageous embodiment of the base plate in the form of an irregular polygon, the variability of the arrangement is improved relative to the cross-sectional area of the concrete support.

Insbesondere bei einer Ausbildung der Anordnung, bei der die beiden Seitenbleche im Bereich ihrer einander zugewandten hinteren Hochkanten einen Abstand zueinander aufweisen, ist eine Befestigung der Armierungsstäbe an den beiden Seitenblechen erheblich vereinfacht. Zwischen den beiden Seitenblechen hindurch kann von beiden Seiten auf die Armierungsstäbe zugegriffen und ohne räumliche Einschränkung eine Schweißnaht zur Festlegung der Armierungsstäbe erzeugt werden. Eine zuverlässige und in ihrer Qualität ohne Einschränkung überprüfbare Festlegung der Armierungsstäbe ergibt sich entweder über eine direkte Verschweißung der Armierungsstäbe mit den Seitenblechen oder durch Festschweißen einer Gewindehülse, in die ein entsprechender Armierungsstab mit einem Gewindekopf eingeschraubt werden kann.In particular, in an embodiment of the arrangement in which the two side plates in the region of their mutually facing rear edges have a distance from one another, attachment of the reinforcing bars on the two side plates is considerably simplified. Through between the two side panels, the reinforcing bars can be accessed from both sides and, without spatial restriction, a weld seam can be created to fix the reinforcing bars. A reliable and verifiable in their quality without restriction determination of the reinforcing bars is obtained either by direct welding of Armierungsstäbe with the side plates or by welding a threaded sleeve into which a corresponding reinforcing rod can be screwed with a threaded head.

Die spitzwinklige Anordnung der beiden Seitenbleche zueinander erlaubt eine universelle Einsetzbarkeit der Stützenschuhe nicht nur im Bereich von Pfeilerkanten, sondern auch bei einer mittigen Anordnung im Bereich einer Bauteilseitenfläche.The acute-angled arrangement of the two side panels relative to each other permits a universal applicability of the column shoes not only in the area of pier edges but also in the case of a central arrangement in the area of a component side face.

In zweckmäßiger Weiterbildung verläuft zwischen den hinteren Enden der beiden seitlichen Kanten der Grundplatte im Bereich der einander zugewandten Hochkanten der Seitenbleche eine hintere Querkante. Die Erstreckung der Grundplatte ist dabei im wesentlichen durch die hinteren Hochkanten der Seitenbleche beschränkt. Entsprechende Stützenschuhe können auch in vergleichsweise kleinen Betonquerschnitten verbaut werden, ohne daß die jeweiligen Grundplatten sich gegenseitig überschneiden.In an expedient development, a rear transverse edge extends between the rear ends of the two lateral edges of the base plate in the region of the mutually facing vertical edges of the side plates. The extent of the base plate is limited essentially by the rear edges of the side panels. Corresponding column shoes can also be installed in comparatively small concrete sections, without the respective base plates overlapping one another.

Zur einfachen Fixierung eines Stützenschuhes während des Vergießens in einem Betonteil ist an der hinteren Querkante der Grundplatte ein Fixierelement insbesondere in Form eines aus der Ebene der Grundplatte hochgebogenen Armierungsstabes vorgesehen. Die Anordnung an der hinteren Querkante führt dazu, daß das Fixierelement hinreichend weit zu den Armierungsstäben an den Seitenblechen beabstandet ist. Die Position der seitlichen Armierungsstäbe kann frei gewählt werden, ohne daß eine Überschneidung oder ein unerwünscht geringer Abstand sich einstellt.For easy fixation of a column shoe during casting in a concrete part, a fixing element is provided in particular in the form of a bent up from the plane of the base plate Armierungsstabes at the rear transverse edge of the base plate. The arrangement at the rear transverse edge causes the fixing element is spaced sufficiently far to the reinforcing bars on the side plates. The position of the lateral reinforcing bars can be chosen freely, without an overlap or an undesirably small distance adjusts itself.

In vorteilhafter Weiterbildung verlaufen zwischen den beiden seitlichen Kanten im vorderen Bereich der Grundplatte zwei in einem Winkel und insbesondere in einem rechten Winkel zueinander liegende Eckkanten. Es ist eine flächenbündige Anordnung im Bereich der Bauteilecken ermöglicht. Dabei kann eine Ausbildung zweckmäßig sein, bei der zwischen beiden Eckkanten eine Frontkante verläuft. Es entsteht insgesamt ein polygonaler Grundriß der Grundplatte, die eine universelle Positionierung in Bauteilecken oder auch im Bereich von Bauteilseitenflächen ermöglicht.In an advantageous development, between the two lateral edges in the front region of the base plate, two corner edges lying at an angle and in particular at a right angle run. It is a flush arrangement in the area of the corner corners allows. In this case, a training may be expedient in which runs between the two corner edges a front edge. The overall result is a polygonal plan of the base plate, which allows a universal positioning in component corners or in the range of component side surfaces.

In einer zweckmäßigen Ausführung sind die Eckkanten im Bereich der voneinander entfernt liegenden vorderen Hochkanten der Seitenbleche angeordnet. Bei einer bündigen Anlage der Eckkanten an Eckflächen einer Betonstütze sind die Seitenbleche bis zu den Eckflächen der Betonstütze vorgezogen. Zusätzliche Verschalungsmaßnahmen beim Eingießen sind nicht erforderlich.In an expedient embodiment, the corner edges are arranged in the region of the mutually remote front edges of the side panels. In a flush installation of the corner edges on corner surfaces of a concrete support, the side panels are preferred to the corner surfaces of the concrete support. additional Cladding during pouring is not required.

In vorteilhafter Weiterbildung weist das Seitenblech einen Längsschlitz auf, in dem der jeweilige Armierungsstab festgelegt ist. Der Armierungsstab liegt damit zumindest näherungsweise in der Blechebene, was zu einer die Tragfähigkeit erhöhenden zentrischen Krafteinleitung führt. Die beiden Armierungsstäbe haben dabei einen vergleichsweise großen Abstand zueinander. Dies trägt insbesondere in Verbindung mit verkürzten Seitenblechen sowohl zu einer verbesserten Zugänglichkeit der Verschraubung als auch zu einem vereinfachten Lagetoleranzausgleich zweier aneinander anliegender Grundplatten bei. Eine zuverlässige und leicht kontrollierbare Verschweißung ist sowohl von der Innenseite als auch von der Außenseite des jeweiligen Seitenbleches möglich. Die Verschweißung des Armierungsstabes oder einer entsprechenden Gewindehülse zur Aufnahme eines Armierungsstabes kann ohne räumliche Einschränkung einer Qualitätskontrolle unterzogen werden.In an advantageous development, the side plate has a longitudinal slot in which the respective reinforcing rod is fixed. The reinforcing bar is thus at least approximately in the plane of the sheet, resulting in a load-increasing concentric force introduction. The two Armierungsstäbe have a comparatively large distance from each other. This contributes, in particular in connection with shortened side panels, both to an improved accessibility of the screw connection and to a simplified position tolerance compensation of two abutting base plates. A reliable and easily controllable welding is possible both from the inside and from the outside of the respective side plate. The welding of the Armierungsstabes or a corresponding threaded sleeve for receiving a reinforcing rod can be subjected to quality control without physical restriction.

In einer vorteilhaften Variante sind die beiden Seitenbleche an ihren zu der Grundplatte beabstandeten Kanten im Bereich ihrer oberen Enden mit einem Querblech verbunden, wobei an dem Querblech ein oder mehrere Armierungsstäbe festgelegt sind. Mittels des Querbleches lassen sich Armierungsstäbe nahe an der Lochachse des Schraubloches festlegen. Es ergibt sich ein entsprechend günstiger Kraftverlauf im Betonbauteil, ohne daß die Zugänglichkeit der Verschraubung durch die Armierungsstäbe eingeschränkt ist.In an advantageous variant, the two side plates are connected at their spaced from the base plate edges in the region of their upper ends with a cross plate, wherein one or more reinforcing rods are fixed to the cross plate. By means of the transverse plate Armierungsstäbe can be set close to the hole axis of the screw hole. This results in a correspondingly favorable force curve in the concrete component, without the accessibility of the screw being restricted by the reinforcing rods.

Es kann auch eine Variante zweckmäßig sein, bei der die Armierungsstäbe an der jeweiligen Außenseite der Seitenbleche angeschweißt sind. Es ist eine leichte Zugänglichkeit der Schweißnähte gegeben.It may also be a variant appropriate in which the reinforcing bars are welded to the respective outer side of the side plates. There is an easy accessibility of the welds.

Gegebenenfalls kann eine Ausbildung zweckmäßig sein, bei der die voneinander entfernt liegenden vorderen Hochkanten der Seitenbleche von der Grundplatte aus schräg nach hinten verlaufen. Es ergibt sich dabei ein unterer, breiterer Bereich der Seitenbleche, der eine kräftig dimensionierte Verschweißung mit der Grundplatte erlaubt. Durch die schräg nach hinten verlaufende Hochkante werden die Seitenbleche mit zunehmendem Abstand zur Grundplatte schmaler, was den Bewegungsraum eines einzusetzenden Verschraubungswerkzeuges vergrößert.Optionally, a training may be appropriate in which the remote from each other front edges of the side panels of the base plate extending obliquely backwards. This results in a lower, wider area of the side plates, which allows a strongly dimensioned welding to the base plate. Due to the obliquely rearwardly extending high edge, the side plates become narrower with increasing distance to the base plate, which increases the range of motion of a screwing tool to be used.
