Description

Die Erfindung betrifft einen waagerechten Längsträger zum Abstützen von Verbauplatten, Spundbohlen oder dgl. bei Grabenverbauvorrichtungen, die aus paarweise angeordneten und durch quer zur Grabenlängsachse angebrachte Spreizen auf Abstand haltbaren Verbauwänden bestehen.The invention relates to a horizontal side member for supporting shoring panels, sheet piles or the like. In trench shoring devices, which consist of spaced shoring walls arranged in pairs and by means of spreaders mounted transversely to the trench longitudinal axis.

Beim Grabenverbau ergeben sich dann Schwierigkeiten, wenn der ausgehobene Graben durch Rohrleitungen oder dgl. gekreuzt wird, die nicht gerade an den Enden einer Verbauplatte angeordnet sind, auch wenn diese in verschiedenen Standardlängen angeboten werden. In solchen Fällen muß der Verbau des Grabens unterbrochen werden und muß dort eine provisorische Verschalung nach Art der früher üblichen Holzverschalungen oder eine Rammdielenverschalung eingebaut werden. Diese Stellen sind nicht nur besonders gefährdet, sondern sind auch sehr lohnintensiv. Darüber hinaus stören sie das ganze Verbausystem.Difficulties arise when digging trenches if the excavated trench is crossed by pipelines or the like, which are not exactly arranged at the ends of a shoring plate, even if they are offered in different standard lengths. In such cases, the construction of the trench must be interrupted and a temporary formwork in the manner of the previously used wooden formwork or a ram board formwork must be installed there. These positions are not only particularly at risk, but are also very wage-intensive. In addition, they interfere with the entire shoring system.

Ähnliche Probleme ergeben sich auch dann, wenn sich die Grabenbreite plötzlich vergrößert und für den quer zur Grabenlängsachse erforderlichen Verbau keine genügend kurze Verbauplatten zur Verfügung stehen.Similar problems arise when the trench width suddenly increases and there are no sufficiently short shoring plates available for the shoring required transversely to the longitudinal axis of the trench.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, für diese Fälle einen Längsträger zu schaffen, der es ermöglicht, die Verbauvorrichtungen an solchen Unterbrechungs- oder Störungsstellen systemkonform miteinander zu verbinden, damit hier, den Umständen entsprechend, gegebenenfalls auch kleinflächige Verbauelemente eingesetzt werden können.The present invention is therefore based on the object of providing a longitudinal member for these cases, which makes it possible to connect the shoring devices to one another in such a way that they conform to the system at such interruptions or malfunctions, so that here, the circumstances speaking, possibly also small-area shoring elements can be used.

Die Lösung der gestellten Aufgabe besteht gemäß der Erfindung darin, daß die Endteile des Längsträgers jeweils um lotrechte Achsbolzen schwenkbar in je einer Konsole gelagert sind, die einstückig mit einem Klemmschuh verbunden ist, der aus einem mit seiner Längsachse parallel zum Achsbolzen ausgerichteten C-Profil besteht, dessen Nutöffnung vom Längsträger wegweist und daß im Steg des KLemmschuhes mindestens eine senkrecht zu seiner Achse ausgerichtete Spannschraube eine Klemmbacke trägt, deren Breite größer ist als die Nutbreite des C-Profils.The solution to the problem is, according to the invention, that the end parts of the side member are each pivotable about vertical axle bolts in a bracket, which is integrally connected to a clamping shoe, which consists of a C-profile aligned with its longitudinal axis parallel to the axle bolt , whose slot opening points away from the longitudinal member and that in the web of the clamping shoe at least one clamping screw oriented perpendicular to its axis carries a clamping jaw, the width of which is greater than the slot width of the C-profile.

Derartige Längsträger ersetzen die bekannten im Holzverbau üblichen "Brusthölzer" und haben den Vorteil, daß sie mit ihren Klemmschuhen sowohl an den Führungsköpfen der Verbauplatten als auch an C-profilartigen Führungen oder Führungsstützen befestigbar sind und auf diese Weise fest mit dem vorhandenen Großflächenverbau verbindbar sind. Ihre Schwenkbarkeit ermöglicht auch die Weiterführung des Verbaues im Wnkel zur bisherigen Richtung. Sie können sogar im rechten Winkel zur Verbauplatte nach außen oder innen geschwenkt werden und als Abstützung für Grabenerweiterungen oder für einen Grabenabschluß dienen.Such side members replace the well-known "chest pieces" in wood shoring and have the advantage that they can be attached with their clamping shoes to the guide heads of the shoring panels as well as to C-profile-like guides or guide supports and can thus be firmly connected to the existing large area shoring. Their swiveling also allows the shoring to be continued in the angle to the previous direction. They can even be swiveled outwards or inwards at right angles to the shoring plate and serve as a support for trench extensions or for a trench closure.

Vorteilhaft 'besteht der Längsträger aus mindestens zwei gegeneinander längsverschiebbaren und aneinander gehaltenen Endteilen. Hierdurch ist es möglich, den Längsträger den örtlichen Gegenebenheiten anzupassen.The longitudinal member advantageously consists of at least two end parts which are longitudinally displaceable and held together. This makes it possible to adapt the side member to the local flatness.

Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche 3 und 4.Further features of the invention are the subject of dependent claims 3 and 4.

  • Fig. 7 is a plan view of a shoring and
  • Fig. 8 is a plan view of a shoring with a suddenly expanding trench.

Die Fig. 1 und 2 zeigen dia als T-förmige Leisten ausgebildeten Führungsköpfe 2 zweier miteinander fluchtender, aber durch eine nicht näher dargestellte Störungsstelle voneinander mit Abstand angeordneter Verbauplatten 1, die als Schachtplatten mit nahe den Führungsköpfen 2 auf der Innenseite der Verbauplatten 1 angebrachten Führungen 3 für nicht dargestellte Spreizen ausgebildet sind.1 and 2 show the guide heads 2, which are designed as T-shaped strips, of two mounting plates 1 which are aligned with one another but are spaced apart from one another by a fault location which is not shown in more detail and which are mounted as shaft plates with guides close to the guide heads 2 on the inside of the mounting plates 1 3 are designed for spreading, not shown.

Jeder Führungskopf 2 liegt an der Innenseite zweier Schenkel 4 eines im Profil C-förmigen KLemmschuhes 5 an und wird gegen diese mittels einer Klemmbacke 6 angedrückt, die mit durch den Steg 7 des Klemmschuhes 5 ragenden Spannschrauben 8 verbunden ist.Each guide head 2 rests on the inside of two legs 4 of a clamping shoe 5 which is C-shaped in profile and is pressed against it by means of a clamping jaw 6 which is connected to clamping screws 8 projecting through the web 7 of the clamping shoe 5.

Einstückig mit jedem Klemmschuh 5 ist eine C-oder gabelförmige Konsole 9 verbunden, durch die ein Achsbolzen 10 gesteckt ist, dessen Achsrichtung parallel zur Achsrichtung des Klemmschuhes 5 ist.A C-shaped or fork-shaped bracket 9 is connected in one piece to each clamping shoe 5, through which an axle bolt 10 is inserted, the axial direction of which is parallel to the axial direction of the clamping shoe 5.

In jeder Konsole 9 ist schwenkbar ein Endteil 11 eines Längsträgers 12 aufgenommen, der mindestens in einem Endteil 11 teleskopisch verschiebbar ist. Der Längsträger 12 kann auch aus mehreren teleskopisch ineinander verschiebbaren Rohren bestehen. Die Länge des Längsträgers 12 läßt sich so den örtlichen Erfordernissen anpassen.In each bracket 9, an end part 11 of a longitudinal member 12 is pivotally received, which is telescopically displaceable in at least one end part 11. The longitudinal Carrier 12 can also consist of several telescopically movable tubes. The length of the longitudinal beam 12 can thus be adapted to local requirements.

An der Außenseite des Klemmschuhes 5 ist ferner ein den Spalt zwischen ihm und der Verbauplatte 1 überdeckendes Abdeckblech 13 angebracht.On the outside of the clamping shoe 5 there is also a cover plate 13 covering the gap between it and the lining plate 1.

Die Fig. 3-5 zeigen im wesentlichen die gleiche Vorrichtung, jedoch mit dem Unterschied, daß hier die Klemmbacken 16 verwendet sind, die sich außerhalb der Schenkel 4 des Klemmschuhes 5 befinden und mit Spannschrauben 18 gegen die Schenkel 14 einer Führungsstütze 15 gedrückt werden, die zu einem Randträgerverbau gehört.3-5 show essentially the same device, but with the difference that here the clamping jaws 16 are used, which are located outside the legs 4 of the clamping shoe 5 and are pressed with clamping screws 18 against the legs 14 of a guide support 15, that belongs to a truss shoring.

Um die erfindungsgemäße Vorrichtung für beide Ausführungsbeispiele verwenden zu können, brauchen die Spannschrauben und Klemmbacken jeweils nur umgesteckt werden. Die Zeichnung zeigt Ausführungen,bei denen die Abstände der Spannschrauben 8,18 je nach Anordnung der Klemmbakken 6,16 verschieden sind. Es können aber auch die gleichen Spannschrauben und KLemmbacken verwendet werden.In order to be able to use the device according to the invention for both exemplary embodiments, the clamping screws and clamping jaws only need to be repositioned. The drawing shows versions in which the distances between the clamping screws 8.18 differ depending on the arrangement of the clamping jaws 6.16. However, the same clamping screws and clamping jaws can also be used.

Um eine leichtere Einstellung der Spannschrauben 8 bei dem in Fig. 1 und 2 gezeigten Ausführungsbeispiel zu ermöglichen, sind hierfür, wie Fig. 4 zeigt, waagerechte Langlöcher 17 im Klemmschuh 5 vorgesehen.In order to enable easier adjustment of the clamping screws 8 in the embodiment shown in FIGS. 1 and 2, horizontal elongated holes 17 are provided in the clamping shoe 5, as shown in FIG. 4.

Die Fig. 6-8 zeigen Anwendungsbeispiele der erfindungsgemäßen Längsträger bei verschiedenen Grabenverbauen.6-8 show application examples of the longitudinal beams according to the invention in various trench shoring.

In Fig. 6 sind zwei fluchtende, jedoch axial mit Abstand voneinander angeordnete Verbauplatten 19,20 vorgesehen. Der von ihnen abgestützte, nicht dargestellte Graben wird von einer strichpunktiert dargestellten Rohrleitung 21 gekreuzt.In Fig. 6 two aligned, but axially spaced shoring plates 19, 20 are provided. The trench, not shown, supported by them is crossed by a pipeline 21 shown in dash-dot lines.

An den Enden der Verbauplatten 19,20 sind KLemmschuhe 5 befestigt, die von teleskopisch ausziehbaren und schwenkbaren Längsträgern 12 miteinander verbunden sind. An den Außenseiten der Längsträger 12 sind kleinflächige Verbauelemente, z.B. Kanaldielen 22 mit trapezförmigem Profil so angeordnet, daß die Verbaulücke weitgehend abgesichert ist.Clamping shoes 5 are fastened to the ends of the shoring plates 19, 20 and are connected to one another by telescopically extendable and pivotable longitudinal beams 12. Small-area shoring elements, e.g. Channel boards 22 with a trapezoidal profile arranged so that the installation gap is largely secured.

Fig. 7 zeigt eine Anwendung eines Längsträgers 12, wobei dieser zwei gegenüberliegende Verbauplatten 19 miteinander verbindet und ein Grabenschott als Abschluß des Verbaues ermöglicht. Dieses Grabenschott wird wiederum von kleinflächigen Verbauelementen, z.B. Kanaldielen 22 gebildet.Fig. 7 shows an application of a longitudinal beam 12, which connects two opposing shoring panels 19 together and allows a trench bulkhead to complete the shoring. This trench bulkhead is in turn covered by small-area shoring elements, e.g. Channel planks 22 formed.

Fig. 8 zeigt eine Grabenerweiterung. Zum Ausgleich der sich ändernden Grabenweite sind an den Enden der Verbauplatten 19,20 und 23 jeweils Klemmschuhe 5 mit sie verbindenden Längsträgern 12 angebracht, an denen sich Kanaldielen 22 od. dgl. abstützen, die die Weitenunterschiede überbrücken.8 shows a trench extension. To compensate for the changing trench width, clamping shoes 5 are attached to the ends of the shoring plates 19, 20 and 23 with longitudinal members 12 connecting them, on which channel boards 22 or the like are supported, which bridge the differences in width.
