Description

Die Erfindung betrifft eine Vorrichtung zum Einpressen von Nagelplatten in aneinander anliegende Balken od.dgl., mit einer Einrichtung zum Zusammenpressen der Balken od.dgl., in welche die Nagelplatte(n) einzudrücken ist (sind) in welcher Einrichtung die miteinander zu verbindenden Balken od.dgl. gegen ein Widerlager gedrückt werden und mit wenigstens einer von dieser unabhängig betätigbaren, an einem bügelförmigen Träger angeordneten Einrichtung zum Eindrücken der Nagelplatten in die aneinandergepressten Balken od.dgl., die einander gegenüberliegend angeordnete Druckplatten aufweist, von welchen wenigstens eine durch einen Antriebsmotor vorschiebbar ist, wobei die Wirkrichtung der Einrichtung zum Zusammenpressen der aneinander anliegenden Balken od.dgl. senkrecht zur Wirkrichtung der Einrichtung zum Einpressen der Nagelplatte(n) verläuft.The invention relates to a device for pressing nail plates into adjoining beams or the like, with a device for pressing the beams together or the like, into which the nail plate (s) is (are) to be pressed, in which device the beams to be connected or the like. be pressed against an abutment and with at least one device which can be actuated independently of this and is arranged on a bow-shaped support for pressing the nail plates into the pressed bars or the like, which has pressure plates arranged opposite one another, at least one of which can be pushed forward by a drive motor, the direction of action of the device for pressing together the abutting beams or the like. perpendicular to the direction of action of the device for pressing in the nail plate (s).

Die Anfertigung von Verbundträgern bzw. die Errichtung von Dach- und Rahmenkonstruktionen auf Baustellen könnte durch den Einsatz von Nagelplatten wesentlich vereinfacht und beschleunigt werden. Das Eindrücken von Nagelplatten mit Hammerschlägen, was sich auf Baustellen anbieten würde, bringt keine satte Verbindung der Balken und somit eine verminderte Tragfähigkeit. Ausserdem werden die Nagelplatten hiebei häufig zerstört und grössere Nagelplatten sind auf diese Weise überhaupt nicht einbringbar.The manufacture of composite beams or the erection of roof and frame structures on construction sites could be significantly simplified and accelerated by using nail plates. The pushing in of nail plates with hammer blows, which would offer itself on construction sites, does not bring a full connection of the beams and thus a reduced load capacity. In addition, the nail plates are often destroyed and larger nail plates cannot be inserted at all in this way.

Es sind daher auch schon Vorrichtungen zum maschinellen Einpressen von Nagelplatten vorgeschlagen worden. Keine dieser z.B. aus der DE-B-16 27 825, der GB-A-1 314 398 oder der DE-A-30 02 770 bekannten Nagelpressen besitzt eine Einrichtung zum Zusammenpressen der miteinander zu verbindenden Balken od.dgl..Devices for mechanically pressing in nail plates have therefore already been proposed. None of these e.g. Nail presses known from DE-B-16 27 825, GB-A-1 314 398 or DE-A-30 02 770 have a device for pressing the beams to be joined together or the like.

Eine Vorrichtung zum Verbinden aneinanderliegender Balken, die eine Einrichtung zum Zusammenpressen der miteinander zu verbindenden Balken besitzt, ist durch den SU-A-852 548 bekannt geworden. Bei der aus dem SU-A-852 548 bekannten Vorrichtung ist die Einrichtung zum Zusammenpressen der Balken an der Vorrichtung starr angebracht, so dass die Balken stets mit einer Fläche am ortsfesten Widerlager anliegen. Bei unterschiedlicher (in Wirkrichtung der Zusammenpresseinrichtung gemessener) Gesamtbreite der miteinander zu verbindenden Balken ergeben sich sohin Probleme mit der Ausrichtung der Nagelplatten-Einpressanordnung gegenüber den Balken.A device for connecting adjacent beams, which has a device for pressing the beams to be connected together, has become known from SU-A-852 548. In the device known from SU-A-852 548, the device for compressing the beams is rigidly attached to the device, so that the beams always rest with a surface on the stationary abutment. If the total width of the beams to be connected (measured in the direction of action of the compression device) is different, problems arise with the alignment of the nail plate press-in arrangement with respect to the beams.

Eine Vorrichtung der im Oberbegriff des unabhängigen Anspruches 1 genannten Gattung ist aus dem SU-A-703 327 bekannt. Diese bekannte Vorrichtung weist eine Einrichtung zum Zusammenpressen der Balken, in welche die Nagelplatte einzudrücken ist, gegen ein Widerlager auf. Weiters ist eine an einem bügelförmigen Träger angeordnete Einrichtung zum Eindrücken der Nagelplatte in die aneinandergepressten Balken vorgesehen, die einander gegenüberliegend angeordnete Druckplatten aufweist, von welchen eine durch einen Antriebsmotor vorschiebbar ist. Die Wirkrichtung der Einrichtung zum Zusammenpressen der Balken verläuft bei der aus dem SU-A-703 327 bekannten Vorrichtung senkrecht zur Wirkrichtung der Einrichtung zum Einpressen der Nagelplatte.A device of the type mentioned in the preamble of independent claim 1 is known from SU-A-703 327. This known device has a device for pressing the beams into which the nail plate is to be pressed against an abutment. Furthermore, a device arranged on a bow-shaped support for pressing the nail plate into the bars pressed against one another is provided, which has pressure plates arranged opposite one another, one of which can be advanced by a drive motor. In the device known from SU-A-703 327, the direction of action of the device for pressing the bars together is perpendicular to the direction of action of the device for pressing in the nail plate.

Ein weiterer Nachteil der bekannten Vorrichtungen besteht darin, dass diese ortsfest ausgebildet sind, so dass die langen und schweren Balken bewegt werden müssen.Another disadvantage of the known devices is that they are stationary so that the long and heavy beams have to be moved.

Aufgabe der Erfindung ist es, eine leicht transportierbare, auch von Hand ausführbare Vorrichtung zu schaffen, mit deren Hilfe Nagelplatten auf Baustellen oder sonstigen beliebigen Orten in Holzbalken eingepresst werden können, wobei die Balken während des Nagelvorganges zusammengespannt werden können und nicht bewegt werden müssen.The object of the invention is to provide an easily transportable device, which can also be carried out by hand, with the aid of which nail plates can be pressed into wooden beams on construction sites or any other place, the beams being clamped together during the nailing process and not having to be moved.

Zur Lösung dieser Aufgabe ist gemäss der Erfindung eine Vorrichtung vorgesehen, die sich dadurch auszeichnet, dass die Einrichtung zum Zusammenpressen der Balken od.dgl. an einem mit dem Träger verbundenen Hilfsrahmen montiert ist, dass der Hilfsrahmen an einer am Träger vorgesehenen Führung, gegenüber dem Träger verschwenkbar und/oder auf- und abverschiebbar gehaltert ist und dass der Träger über Führungsglieder, wie Rollen, Kufen od.dgl. entlang den Balken od.dgl. verfahrbar ist, wobei die Rollen am oberen der Balken oder in sich bekannter Weise an einer zu den Balken od.dgl. parallel angeordneten Führungsschiene bzw. die Rollen am Boden oder entlang von U-Schienen abrollen.To achieve this object, a device is provided according to the invention, which is characterized in that the device for pressing the bars or the like. is mounted on an auxiliary frame connected to the carrier, that the auxiliary frame is held on a guide provided on the carrier, pivotable and / or movable up and down relative to the carrier, and that the carrier is guided by guide members such as rollers, runners or the like. or the like along the bars. is movable, the rollers on the top of the bar or in a known manner on one of the bars or the like. unroll the parallel guide rail or the rollers on the floor or along U-rails.

Die erfindungsgemässe Vorrichtung hat einmal den Vorteil, dass sie in Längsrichtung der miteinander zu verbindenden Balken verfahrbar ist, was wesentlich einfacher und vor allem raumsparender ist als lange und schwere Balken in deren Längsrichtung zu bewegen.The device according to the invention has the advantage that it can be moved in the longitudinal direction of the beams to be connected, which is much simpler and, above all, more space-saving than moving long and heavy beams in their longitudinal direction.

Durch die besondere Ausbildung der Einrichtung zum Zusammenspannen («Spannzange») der erfindungsgemässen Vorrichtung kann die Spannzange vom Umgriff der Balken ausgeschwenkt werden, was die Handhabung der erfindungsgemässen Vorrichtung vereinfacht. Weiter ergibt die besondere Halterung der Spannzange den Vorteil, dass sie sich frei zu den miteinander zu verbindenden Balken einstellen kann, so dass das Gerät beim Zusammenspannen in seiner Lage nicht verändert wird. Mit Hilfe der erfindungsgemäss ausgebildeten Spannzange werden die Balken unmittelbar vor dem Einpressen der Nagelplatten, in geringem Abstand von der Nagelstelle, zusammengespannt.Due to the special design of the device for clamping together (“collet”) of the device according to the invention, the collet can be swung out from around the bars, which simplifies the handling of the device according to the invention. Furthermore, the special mounting of the collet has the advantage that it can adjust freely to the beams to be connected to one another, so that the position of the device is not changed when clamping. With the help of the collet designed according to the invention, the bars are clamped together immediately before the nail plates are pressed in, at a short distance from the nail location.

In einer Ausführungsform kann vorgesehen sein, dass am Hilfsrahmen der Einrichtung zum Zusammenpressen der miteinander zu verbindenden Balken od.dgl. unten ein mit dem Hilfsrahmen starr verbundenes Widerlager und oben eine über einen Druckmittelmotor vorschiebbare. Druckplatte angeordnet ist. Dabei ist bevorzugt, dass der Träger einen längeren Schenkel aufweist und dass die Führung für den Hilfsrahmen am längeren Schenkel des Trägers angeordnet ist.In one embodiment it can be provided that the like on the subframe of the device for pressing together the beams to be connected. below an abutment rigidly connected to the subframe and above one that can be advanced using a pressure medium motor. Pressure plate is arranged. It is preferred that the carrier has a longer leg and that the guide for the auxiliary frame is arranged on the longer leg of the carrier.

Die erfindungsgemäss vorgeschlagene Massnahme, wonach die Führungsglieder, wie Rollen od.dgl. am Träger höhenverstellbar befestigt sind, bietet den Vorteil, dass die Mitte der Druckplatten zum Einpressen der Nagelplatten auch bei Balken verschiedener Stärke jeweils gegenüber der Berührungsfläche der Balken zentriert werden kann. Diese Verstellung kann mit Hilfe eines Druckmittelmotors erfolgen oder es ist gemäss der Erfindung vorgesehen, dass die Rollen am Träger quer zur Wirkrichtung der Einrichtung zum Einpressen der Nagelplatte(n) beispielsweise mit Hilfe eines Spindelantriebes verstellbar befestigt sind.The measure proposed according to the invention, according to which the guide members, such as roles or the like. are attached to the support in a height-adjustable manner, has the advantage that the center of the pressure plates for pressing in the nail plates can also be centered relative to the contact surface of the beams, even with beams of different thicknesses. This adjustment can be carried out with the aid of a pressure medium motor or it is provided according to the invention that the rollers on the carrier are adjustably fastened transversely to the direction of action of the device for pressing in the nail plate (s), for example with the aid of a spindle drive.

Im Rahmen der Erfindung gibt es verschiedene Möglichkeiten, die Vorrichtung entlang der Balken zu verfahren. So kann vorgesehen sein, dass am Träger nach unten weisend Rollen vorgesehen sind, die gegen den oberen der miteinander zu verbindenden Balken von oben her anliegen. Hier erweist sich eine Ausführungsform als vorteilhaft, bei welcher die Rollen am Träger quer zur Wirkrichtung der Einrichtung zum Einpressen der Nagelplatte(n) beispielsweise mit Hilfe eines Spindelantriebes verstellbar befestigt sind.Within the scope of the invention there are various possibilities for moving the device along the bars. It can thus be provided that rollers are provided on the support pointing downwards, which bear against the upper of the beams to be connected from above. Here, an embodiment has proven to be advantageous in which the rollers on the carrier are adjustably fastened transversely to the direction of action of the device for pressing in the nail plate (s), for example with the aid of a spindle drive.

Nach einer anderen Ausführungsform der Erfindung ist vorgesehen, dass die Führungsschiene für die am Träger nach oben weisend vorgesehenen Rollen od.dgl. an einer Halterung befestigt ist, die Auflager für die miteinander zu verbindenden Balken aufweist.According to another embodiment of the invention, it is provided that the guide rail or the like for the rollers provided upward on the carrier. is fastened to a holder which has supports for the beams to be connected to one another.

Statt die Führungsmittel, wie Rollen und dgl. am Träger verstellbar vorzusehen, kann im Rahmen der Erfindung auch vorgesehen sein, dass die Druckplatten gegebenenfalls gemeinsam mit den sie betätigenden Antriebsmotoren am Träger höhenverstellbar gehaltert sind.Instead of providing the guide means, such as rollers and the like, on the support in an adjustable manner, it can also be provided in the context of the invention that the pressure plates, if necessary, are mounted on the support so that they can be adjusted in height together with the drive motors which actuate them.

Erfindung stellt also eine z.B. hydraulische Nagelzange zur Verfügung, die von einem abgesetzten hydraulischen Aggregat über Druckschläuche mit Druckmittel gespeist werden kann, wobei die Nagelzange mit einem Druckzylinder einen begrenzt beweglichen Plattenteller gegen ein gerätefestes, wahlweise wegschwenkbares Widerlager presst. Die Nagelzange kann mittels Rollen od.dgl. auf den zu nagelnden Balken, oder einem parallel zu diesen angeordneten Hilfsrahmen, der auf Balkenhöhe, darunter oder darüber angebracht ist, oder auf Schienen oder einfach am Boden verfahrbar sein.Invention thus represents e.g. Hydraulic nail pliers are available, which can be supplied with pressure medium from a remote hydraulic unit via pressure hoses, the nail pliers using a pressure cylinder pressing a limited-moving platter against a fixed, optionally pivotable abutment. The nail pliers or the like can be by means of rollers. on the beam to be nailed, or a subframe arranged parallel to it, which is attached at beam height, below or above, or on rails or simply on the floor.

Der Vorschub der Zange erfolgt von Hand oder mittels angetriebener Rollen als selbstfahrendes Gerät.The pliers are fed by hand or by means of driven rollers as a self-propelled device.

Die Spannzange, und zwar ihr bügelförmiger Träger, ist so ausgebildet, dass der Arm mit dem Widerlager beim Vorbeibewegen an allfälligen Hindernissen, wie seitlich angesetzten Trägern, Konsolen etc. ausschwenkbar und dann wieder arretierbar ist.The collet, namely its bow-shaped support, is designed so that the arm with the abutment can be swung out and then locked again when moving past any obstacles, such as side-mounted supports, consoles, etc.

Die Nagelplatten werden in den vorgesehenen Abständen vor dem Einpressen z.B. durch Hammerschläge angeheftet. Nagelplatten mit verlängerten Heftnägeln sind hierzu besonders vorteilhaft.The nail plates are removed at the specified intervals before pressing e.g. tacked by hammer blows. Nail plates with extended tack nails are particularly advantageous for this.

Vor dem Einsetzen der Nagelplatten werden die Balken mit Hilfe der in der Vorrichtung vorgesehenen Spanneinrichtung zusammengepresst, so dass diese satt aneinander anliegen.Before the nail plates are inserted, the bars are pressed together with the aid of the tensioning device provided in the device, so that they abut one another.

Um Balken verschiedener Stärke verbinden zu können, ist der Abstand zwischen den Druckplatten der Einrichtung zum Einpressen der Nagelplatte zu den Laufrollen mit Hilfe einer Spindel oder hydraulisch einstellbar, so dass die Tellermitte jeweils im Bereich der Berührungsfläche der Balken zu liegen kommt. Dabei können entweder die Stützglieder und/oder die Druckplatten - diese gegebenenfalls mit ihren Druckmittelmotoren-verstellbar sein.In order to be able to connect beams of different thicknesses, the distance between the pressure plates of the device for pressing in the nail plate to the rollers can be adjusted with the aid of a spindle or hydraulically, so that the center of the plate comes to lie in the area of the contact surface of the beams. Either the support members and / or the pressure plates - these can be adjustable with their pressure medium motors if necessary.

Zur Führung des Gerätes dienen zwei im Abstand aufgesetzte Handgriffe und zum Einsetzen auf Balkenhöhe kann ein Beistellbock mit schiefer Ebene, oder eine Winde zum Anheben des Gerätes verwendet werden. In der Regel werden die Balken auf Böcke, Schragen etc. aufgelegt, so dass diese etwa horizontal liegen und das Gerät mit den Laufrollen an der Oberseite des oberen Balkens abgestützt, leicht verschiebbar ist.Two handles are placed at a distance to guide the device, and a trestle with an inclined plane or a winch for lifting the device can be used to insert it at bar height. As a rule, the beams are placed on trestles, slants, etc., so that they are roughly horizontal and the device is supported by the rollers on the top of the upper beam and is easy to move.

Das Gerät kann aber die Laufrollen auch so angeordnet haben, dass diese auf einer beistellbaren Schiene abgestützt sind. Es ist auch möglich, ein langgestrecktes Gestell mit Haltern zur Auflage der Balken vorzusehen, das parallel zu diesen eine Führungsschiene aufweist, entlang welcher das Gerät verfahrbar ist. Hiebei kann die Führungsschiene in beliebiger Lage zu den Balken angeordnet sein, vorzugsweise wird diese Führungsschiene im Abstand über den Balken, ähnlich einer Hängebahn, angebracht, um den Arbeitsbereich möglichst frei zu halten.The device can also have the rollers arranged so that they are supported on an optional rail. It is also possible to provide an elongated frame with holders for supporting the beams, which has a guide rail parallel to these, along which the device can be moved. The guide rail can be arranged in any position relative to the beams, this guide rail is preferably attached at a distance above the beam, similar to a suspension track, in order to keep the working area as free as possible.

Das Gerät kann auch so eingesetzt werden, dass die Balken zum Nageln nebeneinanderliegend aufgelegt werden.The device can also be used so that the bars are placed side by side for nailing.

Im Rahmen der Erfindung kann die Spannzange zum Zusammenpressen der miteinander zu verbindenden Balken auch anders als bisher beschrieben ausgebildet sein. So kann sich die Vorrichtung der eingangs genannten Gattung auch dadurch auszeichnen, dass die Einrichtung zum Zusammenpressen der Balken od.dgl. wenigstens einen mit dem Träger verbundenen Druckmittelmotor aufweist, der etwa in der Mitte des Trägers angebracht ist, der gegen den oberen der miteinander zu verbindenden Balken wirkt und der die Balken od.dgl. gegen ein Widerlager drückt und dass der Träger über Führungsglieder, wie Rollen, Kufen od.dgl. entlang den Balken od.dgl. verfahrbar ist, wobei die Rollen am oberen der Balken oder in an sich bekannter Weise an einer zu den Balken od.dgl. parallel angeordneten Führungsschiene bzw. die Rollen am Boden oder entlang von U-Schienen abrollen. Diese Ausführungsform zeichnet sich ohne Beeinträchtigung der Funktion durch grosse Einfachheit aus.Within the scope of the invention, the collet for pressing the beams to be joined together can also be designed differently than previously described. So the device of the type mentioned can also be characterized in that the device for pressing the bars or the like. has at least one pressure medium motor connected to the carrier, which is mounted approximately in the middle of the carrier, which acts against the upper of the beams to be connected and which or the like. presses against an abutment and that the carrier via guide members, such as rollers, runners or the like. or the like along the bars. is movable, the rollers on the top of the bar or in a known manner on one of the bars or the like. unroll the parallel guide rail or the rollers on the floor or along U-rails. This embodiment is characterized by great simplicity without impairing the function.

Bei dieser Ausführungsform der erfindungsgemässen Vorrichtung können die Widerlager verschieden ausgebildet sein. Beispielsweise ist es möglich, dass die am Boden abrollenden Rollen an den freien Enden des Trägers vorgesehen sind und dass das Widerlager eine die Balken untergreifende, an den Schenkeln des Trägers vorzugsweise lösbar festgelegte Querstange ist.In this embodiment of the device according to the invention, the abutments can be designed differently. For example, it is possible for the rollers rolling on the floor to be provided at the free ends of the carrier and for the abutment to be a transverse rod which engages underneath the beams and is preferably detachably fixed to the legs of the carrier.

Nach einer Variante der Erfindung kann vorgesehen sein, dass an den freien Enden des Trägers in am Boden befestigte U-Schienen eingreifende Führungsglieder, wie Rollen, Kufen od.dgl. vorgesehen sind, wobei die Stege der U-Schienen hochkant stehend ausgerichtet sind und die Führungsglieder von aussen oder bevorzugt von innen in die U-Schienen eingreifen und dass als unteres Widerlager der Einrichtung zum Zusammenpressen der miteinander zu verbindenden Balken am Boden angeordnete Auflager für die Balken vorgesehen sind.According to a variant of the invention it can be provided that guide members, such as rollers, runners or the like, engage at the free ends of the carrier in U-rails fastened to the floor. are provided, wherein the webs of the U-rails are aligned upright and the guide members engage from outside or preferably from the inside in the U-rails and that as a lower abutment of the device for pressing the beams to be joined together, supports arranged on the floor for the beams are provided.

Die in den Figuren 1, 2 und 3 gezeigte Ausführungsform der erfindungsgemässen Vorrichtung 1 («Nagelzange») besitzt einen Träger 2, der im gezeigten Ausführungsbeispiel als im wesentlichen U-förmiger Bügel ausgebildet ist. Am Träger 2 ist eine Einrichtung 3 zum Einpressen von Nagelplatten 4 in Balken od.dgl. aus Holz 5 und 6 und weiters eine Einrichtung 7 in Form einer Spannzange zum Zusammenpressen der Balken 5 und 6 wenigstens während des Einpressens der Nagelplatten 4 angeordnet.The embodiment of the device 1 according to the invention (“nail pliers”) shown in FIGS. 1, 2 and 3 has a carrier 2 which, in the exemplary embodiment shown, is designed as an essentially U-shaped bracket. On the carrier 2 is a device 3 for pressing nail plates 4 into beams or the like. made of wood 5 and 6 and further a device 7 in the form of a collet for pressing the beams 5 and 6 together at least during the pressing in of the nail plates 4.

Aus Figur 1 ist ersichtlich, dass die Wirkrichtungen der Einrichtungen 3 und 7 zueinander senkrecht stehen.It can be seen from FIG. 1 that the directions of action of the devices 3 and 7 are perpendicular to one another.

Die Einrichtung 3 umfasst zwei Druckplatten 12, von welchen eine durch einen Druckmittelzylinder 9, der über eine Leitung 11 mit Druckmittel beaufschlagt werden kann, auf die Balken 5 und 6 zu vorschiebbar ist. Die andere Druckplatte 12' ist am Träger 2 in einer Führung 8 geführt und kann mittels einer Stellvorrichtung 10 in der gewünschten Lage (entsprechend der Breite der Balken 5 und 6) justiert werden. Wird die Druckplatte 12 vorgeschoben, dann werden die Nagelplatten 4 von den Druckplatten 12 und 12' in die Balken 5,6 eingepresst.The device 3 comprises two pressure plates 12, one of which can be pushed onto the beams 5 and 6 by a pressure medium cylinder 9, which can be pressurized with pressure medium via a line 11. The other pressure plate 12 'is guided on the carrier 2 in a guide 8 and can be adjusted in the desired position (corresponding to the width of the bars 5 and 6) by means of an adjusting device 10. If the pressure plate 12 is advanced, then the nail plates 4 are pressed into the beams 5, 6 by the pressure plates 12 and 12 '.

Die Einrichtung 7 zum Zusammenpressen der Balken 5 und 6 während des Einpressens von Nagelplatten 4 in die Balken 5 und 6 besitzt einen an einer Führung 13 gegenüber dem Träger 2 verschiebbar gehalterten Hilfsrahmen 14, der unten ein Widerlager 15 und oben einen Druckmittelmotor 16 aufweist, wobei die Kolbenstange 17 des Druckmittelmotors 16 eine Druckplatte 18 aufweist, die zum Zusammenpressen der Balken 5, 6 auf das Widerlager 15 zu vorschiebbar ist. Hiezu ist der Druckmittelmotor 16 über eine Leitung 19 mit Druckmittel beaufschlagbar.The device 7 for pressing the bars 5 and 6 together during the pressing of nail plates 4 into the bars 5 and 6 has an auxiliary frame 14 which is slidably mounted on a guide 13 relative to the carrier 2 and which has an abutment 15 at the bottom and a pressure medium motor 16 at the top, wherein the piston rod 17 of the pressure medium motor 16 has a pressure plate 18 which can be pushed onto the abutment 15 in order to compress the beams 5, 6. For this purpose, the pressure medium motor 16 can be acted upon with pressure medium via a line 19.

Wie die Figuren 2 und 3 zeigen, ist der Hilfsrahmen 14 gegenüber dem Träger 2 an der Führung 13 verschwenkbar gehaltert, so dass die Vorrichtung 7 aus ihrer Wirkstellung weggeschwenkt werden kann (strichlierte Stellung in Figur 2).As FIGS. 2 and 3 show, the auxiliary frame 14 is pivotably supported on the guide 13 relative to the carrier 2, so that the device 7 can be pivoted away from its operative position (dashed position in FIG. 2).

Der Schenkel 20 des Trägers 2, an dem die Führung 13 für die Einrichtung 7 angeordnet ist, weist ein Gelenk 21 auf, so dass die Vorrichtung 1 gekippt werden kann, wobei sich die Druckplatte 12' von den Balken 5 und 6 wegbewegt, so dass die Vorrichtung 1 an von den Balken 5 und 6 abstehenden Trägern, Konsolen u.dgl. vorbeibewegt werden kann. Bei der bestimmungsgemässen Benutzung der Vorrichtung 1 wird die freie Verschwenkbarkeit des Schenkels 20 des Trägers 2 durch Einsetzen eines Bolzens 22 unterbunden.The leg 20 of the carrier 2, on which the guide 13 for the device 7 is arranged, has a joint 21, so that the device 1 can be tilted, the pressure plate 12 'moving away from the beams 5 and 6, so that the device 1 on beams, brackets and the like protruding from the beams 5 and 6. can be moved past. When the device 1 is used as intended, the free pivotability of the leg 20 of the carrier 2 is prevented by inserting a bolt 22.

Damit die Vorrichtung 1 entlang der Balken 5 und 6 verschoben werden kann, ist ihr Träger 2 mit Rollen 23 ausgerüstet, die von oben am oberen Balken 5 anliegen. Die Halterung 24 für die Rollen 23 ist mit Hilfe einer Schraubspindel 25 oder mit Hilfe eines Druckmittelzylinders (nicht gezeigt) gegenüber dem Träger 2 verstellbar, so dass die Vorrichtung 1 gegenüber den Balken 5 und 6 so ausgerichtet werden kann, dass die Druckplatten 12 der Einrichtung 3 stets gegenüber der Berührungsfläche zwischen den Balken 5 und 6 zentriert sind, wenn Nagelplatten 4 eingepresst werden sollen.So that the device 1 can be moved along the bars 5 and 6, its carrier 2 is equipped with rollers 23 which abut the upper bar 5 from above. The holder 24 for the rollers 23 is adjustable with the aid of a screw 25 or with the aid of a pressure medium cylinder (not shown) relative to the carrier 2, so that the device 1 can be aligned with the beams 5 and 6 such that the pressure plates 12 of the device 3 are always centered with respect to the contact surface between the bars 5 and 6 when nail plates 4 are to be pressed in.

Die in den Figuren 4 und 5 gezeigte Ausführungsform der erfindungsgemässen Vorrichtung 26 besitzt, was den Träger 2 und die an ihm befestigten Einrichtungen 3 und 7 anlangt, einen der in den Figuren 1 bis 3 gezeigten Ausführungsform entsprechenden Aufbau. Dabei kann, obwohl in den Figuren 4 und 5 nicht gezeigt, der Träger 2 wie bei der in Figur 1 gezeigten Ausführungsform einen wegschwenkbaren Schenkel 20 besitzen.The embodiment of the device 26 according to the invention shown in FIGS. 4 and 5 has a structure corresponding to the embodiment shown in FIGS. 1 to 3 as far as the carrier 2 and the devices 3 and 7 attached to it are concerned. Here, although not shown in FIGS. 4 and 5, the carrier 2 can have a leg 20 which can be pivoted away, as in the embodiment shown in FIG.

Wie bei der Vorrichtung 1 umfasst die Einrichtung 3 zum Einpressen der Nagelplatten 4 in die Balken 5 und 6 einen Druckmittelzylinder 9, welcher der Druckplatte 12 zugeordnet ist, wogegen die in Figur 5 links eingezeichnete Druckplatte 12' als gerätfestes Widerlager ausgebildet ist, dessen Lage gegenüber dem Träger 2 mit Hilfe einer Stellspindel od.dgl. eingestellt werden kann. Es ist aber auch möglich, beiden Druckplatten 12 gleichzeitig mit Druckmittel beaufschlagbare Druckmittelmotore oder sonstige Antriebe zum Vorschieben zuzuordnen, so dass sich beim Einpressen von Nagelplatten beide Druckplatten 12 auf die Balken 5 und 6 zu bewegen.As with the device 1, the device 3 for pressing the nail plates 4 into the beams 5 and 6 comprises a pressure medium cylinder 9, which is assigned to the pressure plate 12, whereas the pressure plate 12 'shown on the left in FIG. 5 is designed as an abutment which is fixed to the device, its position opposite the carrier 2 or the like with the aid of an adjusting spindle. can be adjusted. However, it is also possible to simultaneously assign pressure medium motors or other drives for advancing to both pressure plates 12, so that both pressure plates 12 move onto the bars 5 and 6 when nail plates are pressed in.

Aus den Figuren 4 und 5 ist ersichtlich, dass die Vorrichtung 26 über oder ihr angeordnete Rollen 28 an einer horizontalen Schiene 29 verschiebbar abgehängt ist. Zur Zentrierung der Druckplatten 12 der Einrichtung 3 gegenüber der Berührungsfläche der Balken 5 und 6, die auf im wesentlichen horizontalen Auflagern 30 des die Schiene 29 tragenden Gestells 31 aufliegen, ist der Träger über eine Lochleiste 32 und einen Steckbolzen 33, also der Höhe nach verstellbar, mit den Rollen 28 verbunden.It can be seen from FIGS. 4 and 5 that the device 26 can be displaced on a horizontal rail 29 above or above its rollers 28 is suspended. For centering the pressure plates 12 of the device 3 relative to the contact surface of the bars 5 and 6, which rest on essentially horizontal supports 30 of the frame 31 carrying the rail 29, the support can be adjusted via a perforated strip 32 and a plug pin 33, that is to say the height , connected to the rollers 28.

An den Vorrichtungen 1 und 26 sind beispielsweise an deren Träger 2, gegebenenfalls auch am Hilfsrahmen 14, Handgriffe zum Hin- und Herschieben der Vorrichtungen bzw. zum Ausschwenken oder Rückschwenken der Einrichtung 7 zum Zusammenspannen der Balken 5 und 6 vorgesehen. Diese Handgriffe sind in den Zeichnungen der Einfachheit halber nicht dargestellt.On the devices 1 and 26, for example, on the carrier 2, optionally also on the auxiliary frame 14, handles for pushing the devices back and forth or for pivoting or pivoting back the device 7 for clamping the beams 5 and 6 are provided. These handles are not shown in the drawings for the sake of simplicity.

Die Figur 6 zeigt eine am Boden 37 abgestützte Nagelvorrichtung 1, deren Stützräder 34 höhenverstellbar an den freien Enden 35 des Trägers 2 befestigt sind. Die Druckzylinder 9 zum Einpressen der Nagelplatten 4 sind beiderseits angeordnet und über einen Druckausgleich miteinander verbunden. Alternativ oder auch zusätzlich sind die Pressplatten 12 an den Kolben der Zylinder 9 höhenverstellbar. Im Abstand angeordnete Blöcke 36 od.dgl. dienen als Auflager für die Balken 5 und 6.FIG. 6 shows a nail device 1 supported on the floor 37, the support wheels 34 of which are attached to the free ends 35 of the carrier 2 so as to be adjustable in height. The pressure cylinders 9 for pressing in the nail plates 4 are arranged on both sides and connected to one another via a pressure compensation. Alternatively or additionally, the pressure plates 12 on the pistons of the cylinders 9 can be adjusted in height. Blocks 36 or the like arranged at a distance. serve as supports for beams 5 and 6.

Figur 7 zeigt eine Ausführungsform der erfindungsgemässen Vorrichtung, die am Boden 37 in U-Schienen 38 geführt ist. Die Höhenjustierung erfolgt mit Hilfe beweglicher Pressplatten 12 oder auf- und abbeweglicher Druckmittelmotore 9. Der Träger 2 ist schwächer ausgebildet, da dieser beim Pressvorgang beiderseits in den U-Schienen 38 abgestützt ist. Ebenso dienen die U-Schienen beim Zusammenpressen der Balken 5 mit Hilfe der Einrichtung 7 (Druckmittelmotor 16) als Widerlager, wobei der untere Balken 6 gegen Blöcke 36 od.dgl. anliegt. Diese Blöcke 36 dienen somit als unteres Widerlager der Einrichtung 7 zum Zusammenpressen der Balken 5 und 6.FIG. 7 shows an embodiment of the device according to the invention, which is guided on the floor 37 in U-rails 38. The height adjustment is carried out with the aid of movable press plates 12 or pressure medium motors 9 that can be moved up and down. The carrier 2 is weaker because it is supported on both sides in the U-rails 38 during the pressing process. The U-rails also serve as an abutment when the beams 5 are pressed together with the aid of the device 7 (pressure motor 16), the lower beam 6 or the like against blocks 36. is present. These blocks 36 thus serve as the lower abutment of the device 7 for pressing the beams 5 and 6 together.

Die erfindungsgemässe Vorrichtung kann auch dazu verwendet werden, Nagelplatten 4' im Bereich von Stossstellen von aus mehreren Teilen zusammengesetzten Balkenträgern einzupressen. Hiezu wird die Einrichtung 7 zum Zusammenpressen der Balken («Spannzange») verwendet. Diese Möglichkeit ist in Figur 8 dargestellt. Die Nagelplatten 4 werden mit Hilfe der Einrichtung 3 (Druckplatten 12) und die Nagelplatten 4' werden, vorzugsweise vorher, mit Hilfe der Einrichtung 7 eingepresstThe device according to the invention can also be used to press in nail plates 4 'in the region of joints of beam carriers composed of several parts. For this purpose, the device 7 for pressing the beams together (“collet”) is used. This possibility is shown in Figure 8. The nail plates 4 are pressed in using the device 3 (pressure plates 12) and the nail plates 4 ', preferably beforehand, using the device 7

Bei den in den Figuren 7 und 9 gezeigten Ausführungsformen ist die Einrichtung 7 zum Zusammenpressen der miteinander zu verbindenden Balken 5, 6 durch einen Druckstempel mit Druckmittelzylinder 16 gebildet, der von oben nach unten wirkend am Träger 2 etwa in dessen Mitte angebracht ist. Für die Ausbildung des Widerlagers, das die Balken beim Zusammenspannen von unten abstützt, gibt es unter anderem die in den Figuren 7 und 9 gezeigten Möglichkeiten.In the embodiments shown in FIGS. 7 and 9, the device 7 for pressing the beams 5, 6 to be joined together is formed by a pressure ram with a pressure medium cylinder 16, which acts from top to bottom on the carrier 2 approximately in the middle thereof. For the formation of the abutment, which supports the beams from below during clamping, there are, inter alia, the options shown in FIGS. 7 and 9.

Bei der Ausführungsform nach Figur 7 ist als Widerlager eine Querstange 40 vorgesehen, die z.B. in Öffnungen in den Schenkeln des Trägers 2 eingesetzt ist und deren Oberseite vom Boden 37 weg gemessen in der gleichen Höhe wie die Oberseite der Auflager 36 angeordnet ist. Dies kann notfalls durch Höhenverstellung der Rollen 34 herbeigeführt werden.In the embodiment according to FIG. 7, a cross bar 40 is provided as an abutment, which e.g. is inserted into openings in the legs of the carrier 2 and the upper side thereof, measured away from the bottom 37, is arranged at the same height as the upper side of the supports 36. If necessary, this can be brought about by adjusting the height of the rollers 34.

Die Querstange 40 kann seitlich herausgezogen werden, wenn die Vorrichtung im Bereich eines Auflagers verschoben werden soll. Um die Querstange 40 zusätzlich als Abstützung für die Schenkel des Trägers 2 beim Einpressen von Nagelplatten 4 in die Balken 5 und 6 verwenden zu können, sind an der Querstange 40 Anschläge 41 vorgesehen, die von aussen an den Schenkeln des Trägers 2 anliegen. Wenigstens einer der Anschläge 41 ist entfernbar, um die Querstange 40 herausziehen zu können, wenn die Vorrichtung an einem Auflager 36 vorbeigeschoben wird.The crossbar 40 can be pulled out laterally if the device is to be moved in the region of a support. In order to be able to use the crossbar 40 additionally as a support for the legs of the carrier 2 when pressing nail plates 4 into the beams 5 and 6, stops 41 are provided on the crossbar 40, which abut the legs of the carrier 2 from the outside. At least one of the stops 41 can be removed in order to be able to pull out the crossbar 40 when the device is pushed past a support 36.

Bei der Ausführungsform nach Figur 7 ist das Widerlager durch die Auflager 36 gebildet, wobei beim Zusammenspannen der miteinander zu verbindenden Balken 5, 6 das Abheben der Vorrichtung (des Trägers 2) nach oben durch die in die U-Schienen 38 eingreifenden Rollen 34 verhindert wird.In the embodiment according to FIG. 7, the abutment is formed by the supports 36, wherein when the beams 5, 6 to be connected are clamped together, the lifting of the device (the support 2) upwards by the rollers 34 engaging in the U-rails 38 is prevented .

Es kann auch der Fall eintreten, dass Balken 5 und 6 miteinander verbunden werden müssen, bei welchen die Berührungsfläche 42 der Balken 5 und 6 nicht parallel zu Auflageflächen verläuft (z.B. bei entgegengesetzt konischen oder keilförmigen Balken). In diesem Fall würde die Berührungsfläche der Balken 5 und 6 bei Auflagern 36 mit gleicher Höhe schräg ansteigend bzw. abfallend verlaufen. Um dies und ein ständiges Nachjustieren der Platten 12 zu vermeiden, kann vorgesehen sein, dass die Auflager 36 (Figur 7) oder 30 (Figuren 4, 5) so an Höhe zunehmen (d.h. eine insgesamt geneigte Auflagefläche definieren) dass die Berührungsfläche parallel zur Bewegungsbahn (z.B. dem Boden 37) der Vorrichtung verläuft, sie dies schematisch in Figur 10 angedeutet ist.It can also happen that beams 5 and 6 must be connected to one another, in which the contact surface 42 of beams 5 and 6 does not run parallel to contact surfaces (e.g. in the case of oppositely conical or wedge-shaped beams). In this case, the contact surface of the beams 5 and 6 would increase or decrease obliquely with supports 36 of the same height. In order to avoid this and constant readjustment of the plates 12, it can be provided that the supports 36 (FIG. 7) or 30 (FIGS. 4, 5) increase in height (that is to say define an overall inclined support surface) such that the contact surface is parallel to the movement path (eg the bottom 37) of the device, it is indicated schematically in FIG. 10.
