Abstract

A construction assembly for making a collapsible structure has a post extending along and defining an upright post axis and having one end formed with an axially centered threaded bore open in one axial direction, normally upward. A first plate fixed on the post offset in the opposite axial direction, normally downward, from the one end extends generally perpendicular to the axis and is formed with at least one vertically throughgoing cutout offset from the post axis. A frame has a first fitting formed with a projection extending in the opposite direction through the hole and formed on the side of the first plate directed in this opposite direction with a passage that is throughgoing parallel to the first plate, and a second fitting at the one post end and formed with a projection extending in the one direction. A locking member engaged through the passage bears in the one direction on the first plate. A second plate extending generally perpendicular to the post axis is formed at the axis with a throughgoing bore and offset from the axis with a vertically throughgoing cutout through which extends the projection of the second fitting. A bolt threaded in the bore of the post passes through the bore of the second plate and has a head bearing in the opposite direction on the second plate. Thus the bolt presses the second plate down on the second fitting to lock the frame to the post.

Description

Die Erfindung betrifft eine Vorrichtung zur Verbindung von aus Knotenstäben und dazu quer verlaufenden Trägern bestehenden, zerlegbaren Fachwerksbauten, wobei die Knotenstäbe jeweils an einem Ende ein erstes, starres Knotenblech und am anderen Ende ein zweites, lösbares Knotenblech aufweisen, die in ihren den Knotenstab seitlich überragenden Bereichen Ausnehmungen haben, wobei ferner an den gegenüberliegenden Seiten der Träger mindestens je zwei Haken angeordnet sind, welche einander entgegengerichtet die Ausnehmungen der Knotenbleche durchgreifen, und wobei Verriegelungen vorgesehen sind, die eine Einspannung der Träger zwischen den Knotenblechen bewirken.The invention relates to a device for the connection of dismountable half-timbered buildings consisting of tie rods and beams running transversely thereto, the tie rods each having a first, rigid gusset plate at one end and a second, detachable gusset plate at the other end, which laterally project beyond the tie rod Areas have recesses, furthermore at least two hooks are arranged on the opposite sides of the supports, which pass through the recesses of the gusset plates in opposite directions, and interlocks are provided which cause the supports to be clamped between the gusset plates.

Aus der deutschen Offenlegungsschrift 26 25 455 ist eine Verbindung für aus Säulen und quer dazu verlaufenden Trägem bestehende, zerlegbare Fachwerksbauten bekannt, wobei die Säulen aus stockwerkshohen Säulenteilen bestehen, die an ihren Enden über den Querschnitt der Säule hinausragende, in horizontalen Ebenen liegende Knotenbleche mit in ihrem überragenden Bereich vorgesehenen Ausnehmungen aufweisen, wobei an gegenüberliegenden Seiten des Trägers hakenartige Vorsprünge vorgesehen sind, die die Ausnehmungen der Knotenbleche durchgreifen und wobei keilartige Riegel vorgesehen sind, die einen Anzug des Trägers in Richtung auf die Säule und das Knotenblech bewirken.From the German Offenlegungsschrift 26 25 455 a connection is known for separable half-timbered buildings consisting of columns and transverse supports, the columns consisting of floor-to-ceiling column parts, the ends of which protrude beyond the cross-section of the column and lie in horizontal planes with gusset plates have recesses provided in their protruding area, hook-like projections are provided on opposite sides of the carrier, which penetrate through the recesses of the gusset plates, and wedge-like bolts are provided which bring the carrier towards the column and the gusset plate.

Ferner sind hierbei die hakenartigen Vorsprünge von den Trägern seitlich abstrebend angeordnet und die Ausnehmungen in den Knotenblechen sind als in Richtung der angeschlossenen Träger verlaufende Schlitze ausgebildet, in die die Trägerendteile eingesteckt sind, welche Erweiterungen aufweisen, durch die die hakenartigen Vorsprünge hindurchgreifen und. sich mit schrägen Anzugsflächen an den der Säule abgewandten Kanten der Erweiterungen anlegen.Furthermore, the hook-like projections are arranged so as to strut laterally from the supports and the recesses in the gusset plates are designed as slots running in the direction of the connected supports, into which the support end parts are inserted, which have extensions through which the hook-like projections extend and. lie on the edges of the extensions facing away from the column with inclined pull-in surfaces.

Aus der betrieblichen Praxis ist es hierzu außerdem bekannt, anstelle von stockwerkshohen Säulenteilen trägerhohe Knotenstäbe vorzusehen, die sich jeweils von den Untergurten bis zu den Obergurten der Fachwerksträger erstrecken, um mehrere Träger in einem Knotenpunkt freitragend miteinander zu verbinden.In addition, it is known from operational practice to provide support-high node bars instead of floor-to-ceiling column parts, which each extend from the lower chords to the upper chords of the truss girders in order to cantileverly connect several girders to one another at a node.

Dabei ist es allerdings notwendig, jeden Träger am Knotenstab mittels zweier keilförmiger Riegel festzulegen, so daß bei vier in einem Knotenpunkt zusammentreffenden Trägern, also 8 Riegel zu setzen sind.However, it is necessary to fix each girder to the node bar by means of two wedge-shaped bolts, so that when there are four girders meeting at a node, 8 bolts are to be set.

Diese hierbei erforderlichen Maßnahmen sind aber relativ umständlich und zeitraubend.However, the measures required here are relatively cumbersome and time-consuming.

Aufgabe der Erfindung ist es nun, eine Vorrichtung der vorbeschriebenen Art derart zu verbessern, daß unter Beibehaltung der beim Stand der Technik bereits erreichten Vorteile darüber hinaus mit einfachen Mitteln eine erhebliche Vereinfachung der Verbiridungsvorrichtung selbst als auch der Montage erreichbar ist und eine einfachere und preiswertere Herstellung sich ergibt.The object of the invention is now to improve a device of the type described above in such a way that, while maintaining the advantages already achieved in the prior art, a considerable simplification of the connecting device itself and also of the assembly can be achieved with simple means and a simpler and cheaper production arises.

Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß mindestens in einem der die Ausnehmungen des ersten Knotenbleches durchgreifenden Trägerhaken ein Durchbruch angeordnet ist, durch den ein keilförmiges, das erste Knotenblech an den Träger anspannendes Montagewerkzeug hindurchgesteckt ist, und daß in der dem ersten Knotenblech abgewandten Stirnseite des Knotenstabes eine axial gerichtete Gewindebohrung vorgesehen ist, in die eine das zweite, mittig gelochte Knotenblech durchgreifende und mit einem Kopf außenseitig des Knotenbleches sich abstützende Schraube unter axialer Vorspannung eingeschraubt ist.The solution to this problem is characterized in that an opening is arranged in at least one of the support hooks penetrating the recesses of the first gusset plate, through which a wedge-shaped assembly tool is inserted, which clamps the first gusset plate to the support, and in the end face facing away from the first gusset plate an axially directed threaded bore is provided in the knot bar, into which a screw which passes through the second, centrally perforated knot plate and is supported with a head on the outside of the knot plate is screwed under axial prestress.

Jene Ausgestaltung erlaubt die Träger nunmehr wie folgt miteinander zu verbinden : Zunächst wird am freien Ende eines bereits ortsfest gehalterten Trägers der Knotenstab angeschlossen, wobei die untergurtseitigen Haken die Ausnehmungen des starren, ersten Knotenbleches durchgreifen und wobei diese Steckverbindung mittels des keilförmigen Montagewerkzeuges gesichert wird.That configuration now allows the beams to be connected to one another as follows: First, the node rod is connected to the free end of a beam that is already held in a fixed position, the hooks on the lower belt reaching through the recesses of the rigid, first gusset plate, and this plug connection is secured by means of the wedge-shaped assembly tool.

Alsdann können in die anderen Aussparungen des ersten Knotenbleches die weiteren Träger eingehängt werden, wonach nur noch das zweite Knotenblech auf die obergurtseitigen Haken aller Träger aufgesteckt und mit dem Knotenstab mittels der Schraube verbunden werden muß. Danach kann das keilförmige Montagewerkzeug zur Wiederverwendung gelöst werden.Then the other girders can be hooked into the other recesses of the first gusset plate, after which only the second gusset plate has to be plugged onto the hooks of all girders on the upper belt side and connected to the gusset rod by means of the screw. The wedge-shaped assembly tool can then be released for reuse.

Eine material- und gewichtssparende Ausgestaltung besteht hierzu darin, daß der Knotenstab ein regelmäßiges, vieleckiges insbesondere quadratisches Hohlprofil aufweist, und daß in den dem ersten Knotenblech abgewandten Endteil des Knotenstabes eine dem lnnenquerschnitt des Knotenstabes angepaßte Scheibe mit einer zum Knotenstab axial verlaufenden Gewindebohrung fest eingefügt ist.A material- and weight-saving embodiment consists in that the node rod has a regular, polygonal, in particular square, hollow profile, and that a disc adapted to the inner cross section of the node rod with a threaded bore axially extending to the node rod is firmly inserted into the end part of the node rod facing away from the first node plate .

Eine die Montage weiterhin erhebliche Vereinfachung der Weiterbildung ist dadurch gekennzeichnet, daß in dem dem ersten Knotenblech abgewandten Endteil des Knotenstabes in allen Längsseiten je ein achsparallel verlaufender, stirnseitig ausmündender Schlitz angeordnet ist und daß von den Stirnseiten der Träger je ein in den jeweils gegenüber befindlichen Schlitz eingesteckter, mit dem Kopf innenseitig des Knotenstabes sich abstützender Bolzen abstrebt.A further considerable simplification of the further development of the assembly is characterized in that in the end part of the tie rod facing away from the first gusset plate, an axially parallel, front-end slit is arranged in all longitudinal sides and that each of the end faces of the carrier has a slot in the opposite one inserted, struts with the head on the inside of the node rod supporting itself.

Hierdurch sind die Träger bereits schon vor dem Anschluß des zweiten Knotenbleches auch im Bereich ihrer Obergurte relativ zum gemeinsamen Knotenstab lagerichtig gehalten.As a result, the beams are already held in the correct position in the area of their upper straps relative to the common node bar even before the second gusset plate is connected.

Dabei ist es zur Erzielung einer hohen Formfestigkeit des Knotenstabes im Bereich der Schlitze vorteilhaft, wenn die Scheibe nahe der freien Knotenstabstimseite und im Bereich der Schlitze angeordnet ist und daß in der ScheibeIn order to achieve a high dimensional stability of the node rod in the area of the slots, it is advantageous if the disk is arranged near the free node bar end side and in the area of the slots and that in the disk

den Knotenstabschlitzen gegenüber Kopfboizendurchstecköffnungen vorgesehen sind.the knot bar slots are provided opposite to head boice through openings.

Eine weitere vorteilhafte Ausgestaltung des vorbeschriebenen Gegenstandes besteht darin, daß die Schraube eine gegenüber der Hakenlänge so größere Schaftlänge aufweist, daß bei gelockerter, das zweite Knotenblech durchgreifender Schraube und bei vom Knotenstab abgehobenem, zweiten Knotenblech die Träger an den Knotenstab ungehindert anhängbar sind.A further advantageous embodiment of the above-described object is that the screw has a shaft length which is greater than the hook length in such a way that when the screw is loosened and penetrates the second gusset plate and when the second gusset plate is lifted off the knot bar, the supports can be attached to the knot bar without hindrance.

Hierdurch ist das zweite Knotenblech auch während der Montage der Träger mit dem Knotenstab unverlierbar verbunden.As a result, the second gusset plate is captively connected to the gusset rod even during assembly of the carrier.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawings and will be described in more detail below.

Es zeigen

  • Fig. 1 eine Knotenverbindung von Fachwerkträgern während der Montage in der Vorderansicht, teilweise aufgebrochen;
  • Figur 2 desgleichen fertig montiert ;
  • Figur 3 desgleichen in Richtung der Linie 111-111 der Fig. 1 gesehen.
Show it
  • Figure 1 shows a node connection of trusses during assembly in the front view, partially broken away.
  • Figure 2 is also fully assembled;
  • Figure 3 also seen in the direction of line 111-111 of Fig. 1.

Hierbei ist an einem vertikal gerichteten Knotenstab 1 quadratischen Hohlprofiles an dessen unteren Stirnseite ein erstes Knotenblech 2 angeschweiBt.In this case, a first gusset plate 2 is welded to a vertically oriented node bar 1 of a square hollow profile on the lower end face thereof.

In den oberen freien Endteil des Knotenstabes 1 ist eine dem Innenquerschnitt des Knotenstabes angepaßte Scheibe 3 eingefügt, die durch Schweißnähte mit dem Knotenstab 1 unlösbar verbunden ist.In the upper free end part of the node rod 1, a disc 3 is inserted which is adapted to the inner cross section of the node rod and which is permanently connected to the node rod 1 by welds.

Die Scheibe 3 besitzt eine axiale gerichtete Gewindebohrung 4, die durch eine an der Scheibe 3 angeschweißte Schraubenmutter 5 gebildet ist.The disk 3 has an axially directed threaded bore 4, which is formed by a screw nut 5 welded to the disk 3.

In die Gewindebohrung 4 ist eine Kopfschraube 6 eingeschraubt, deren Schaft ein mittig entsprechend gelochtes, zweites Knotenblech 7 so durchgreift, daß sich der Kopf der Schraube 6 außenseitig des Knotenbleches 7 abstützen kann.A head screw 6 is screwed into the threaded bore 4, the shaft of which passes through a second gusset plate 7, which is correspondingly perforated in the center, in such a way that the head of the screw 6 can be supported on the outside of the gusset plate 7.

Die Knotenbleche 2 und 7 sind deckungsgleich ausgebildet, haben eine achteckige Gestalt und reichen allseitig über den Knotenstab 1 hinaus.The gusset plates 2 and 7 are congruent, have an octagonal shape and extend beyond the gusset bar 1 on all sides.

In den den Knotenstab seitlich überragenden Bereichen der Knotenbleche 2 und 7 sind schlitzartige, in Richtung der Fachwerksträger 8 bzw. 9 verlaufende schlitzartige Ausnehmungen 10 vorgesehen.In the regions of the gusset plates 2 and 7 which project laterally beyond the knot bar, slit-like slit-like recesses 10 are provided which run in the direction of the truss girders 8 and 9, respectively.

Ferner sind an den Enden der Fachwerksträger 8 und 9, wie aus der deutschen Offeniegungsschrift 2625455 bekannt, sowohl untergurtseitig als auch obergutseitig jeweils zwei einander entgegengerichtete Haken 11 angeordnet, die die Ausnehmungen 10 durchgreifen.Furthermore, at the ends of the trusses 8 and 9, as is known from German Offenlegungsschrift 2625455, two mutually opposing hooks 11 are arranged on both the lower chord side and the upper goods side, which pass through the recesses 10.

Außerdem sind in den Knotenblechen 2 und 7 noch weitere, nicht dargestellte Ausnehmungen zum Anschluß von ebenfalls nicht gezeigten, weiteren, zu den Fachwerksträgern 8 und 9 rechtwinklig gerichteten Fachwerksträgern vorgesehen.In addition, in the gusset plates 2 and 7 there are further recesses, not shown, for connecting further, also not shown, further truss girders directed at right angles to the truss girders 8 and 9.

In den Haken 11 sind Durchbrüche 12 angeordnet, deren Funktionen noch beschrieben werden.In the hook 11 openings 12 are arranged, the functions of which will be described.

In dem dem Knotenblech 7 zugewandten Endteil des Knotenstabes 1 ist in jeder Knotenstablängsseite den Fachwerksträgern jeweils gegenüber ein längsverlaufender, stirnseitig ausmündender Schlitz 13 angeordnet.In the end part of the node bar 1 facing the gusset plate 7, a longitudinal slot 13 opening on the front side is arranged opposite the truss girders on each longitudinal side of the node bar.

Diesen Schlitzen 13 jeweils gegenüber sind an den Trägern 8 und 9 Kopfbolzen 14 vorgesehen, deren Schäfte in die Schlitze eingesteckt werden können und deren Köpfe sich dann an den innenseitigen Schlitzrändern abstützen. Dabei ist die Länge der Bolzenschäfte nur geringfügig größer als die Dicke der Knotenstabwände.Opposite these slots 13, head bolts 14 are provided on the supports 8 and 9, the shafts of which can be inserted into the slots and the heads of which are then supported on the inside slot edges. The length of the bolt shafts is only slightly larger than the thickness of the node bar walls.

Damit die Scheibe das Einstecken der Kopfbolzen 14 in die Schlitze 13 nicht behindert, sind in der Scheibe 3 noch Kopfbolzendurchstecköffnungen 15 vorgesehen.So that the disc does not impede the insertion of the head bolts 14 into the slots 13, head bolt insertion openings 15 are also provided in the disc 3.

Die Schraube 6 hat eine gegenüber der Länge der Haken 11 so größere Schaftlänge, daß, wie aus der Fig. 1 ersichtlich, bei gelockerter Schraube 6 und bei vom Knotenstab 1 abgehobenen Knotenblech 7 die Träger an dem Knotenstab 1 ungehindert angehängt werden.The screw 6 has a shaft length which is so greater than the length of the hooks 11 that, as can be seen from FIG. 1, when the screw 6 is loosened and the gusset plate 7 is lifted off the gusset bar 1, the girders are attached to the gusset bar 1 unhindered.

Zuvor ist jedoch zunächst der Knotenstab 1 an den mit dem einen Ende bereits ortsfest gehalterter Träger 8 angeschlossen worden, wobei die untergurtseitigen Haken 11 des Trägers 8 die Ausnehmungen 10 des Knotenbleches 2 durchgreifen und wobei in den Durchbruch 12 der Haken 11 ein keilförmiges Montagewerkzeug 16 eingetrieben worden ist, der das Knotenblech 12 fest an die Unterseite des Trägers 8 anpreßt.Prior to this, however, the knot bar 1 was first connected to the support 8, which was already held at one end in a fixed manner, the hooks 11 of the support 8 on the lower belt reaching through the recesses 10 of the gusset plate 2 and a wedge-shaped assembly tool 16 being driven into the opening 12 of the hooks 11 has been, which presses the gusset plate 12 firmly against the underside of the carrier 8.

Außerdem ist gleichzeitig der Kopfbolzen 14 des Trägers 8 in den ihm zugeordneten Schlitz 13 des Knotenbleches 1 eingesteckt worden, so daß der Knotenstab 1 auch obergurtseitig formschlüssig und lagerichtig mit dem Träger 8 verbunden ist.In addition, the head bolt 14 of the carrier 8 has been inserted into the slot 13 of the gusset plate 1 assigned to it, so that the gusset rod 1 is also connected to the carrier 8 in a form-fitting and correct position.

Sind dann alle Träger in den gemeinsamen Knotenstab 1 eingehängt worden, wird das Knotenblech 7 so aufgesteckt, daß die Haken 11 aller Träger die ihnen zugeordneten Ausnehmungen 10 durchgreifen, wonach die Schraube 6 mittels eines Drehmomentschlüssels angezogen wird.Once all the supports have been suspended in the common node rod 1, the gusset plate 7 is attached in such a way that the hooks 11 of all the supports pass through the recesses 10 assigned to them, after which the screw 6 is tightened by means of a torque wrench.

Danach kann das keilförmige Montagegerät zur Wiederverwendung gelöst werden.The wedge-shaped assembly device can then be released for reuse.

Um möglichst kleine Biegemomente im Bereich der Knotenbleche 2 und 7 zu erhalten, stützen sich die Träger 8 und 9 mit relativ kleinen, erhabenen, mit Abstand von den Haken 11 am Ende der Träger angeordneten Flächen 17 an den Knotenstäben 2 bzw. 7 ab.In order to obtain the smallest possible bending moments in the area of the gusset plates 2 and 7, the girders 8 and 9 are supported on the gussets 2 and 7 with relatively small, raised surfaces 17 arranged at a distance from the hooks 11 at the end of the girders.
