Definitions
- the invention relates to a trench shoring device with shoring panels and devices for receiving spacers that can be used between two parallel shoring panels and keep them at a distance, each shoring panel being made of sheet metal by a panel body made of two parallel cover sheets and between these web members arranged in the longitudinal direction of the shoring panel (longitudinal trench direction) are penetrated by reinforcing tubes arranged perpendicular to the longitudinal axes of the web members, and a plate frame which delimits the plate body is formed, which consists of an upper Ambostraverse, a lower end profile and side end profiles.
- the invention has for its object a trench shoring device to create, which is designed so that it has the required static strength with a small wall thickness and at the same time offers the possibility to keep the required trench profile width small.
- FIG. 1 and 2 show a shoring plate 1 for a trench shoring device according to the invention.
- This shoring plate 1 is designed as a so-called "shaft plate”.
- the shoring plate consists of a plate body 2, the construction of which will be explained separately, and a plate frame 3.
- the plate frame 3 is formed by an upper frame part designed as an ambostractor 4, which is equipped with eyelets 5 for the crane attack, a lower end profile 6, to which a cutting edge 8 can be attached, and side end profiles 7, which form the vertical end faces of the plate body 2 limit.
- the lateral end profiles 7 are designed as U-profiles, which are used to hold support shoes, not shown, of the struts that keep the sheeting plates 1 at a distance. Compared to hitherto custom shoring panels, these lateral end profiles 7 lie in the general shoring panel level, so that the mounting rail formed by them for the support shoes does not protrude in front of the side of the shoring panel 1 facing the interior of the trench. This can have notches 13 at the points where retaining bolts for supporting shoes of the spreaders are provided in the lateral end profiles (not shown).
- the side end profile 7 can also consist of three welded U or C profiles.
- two U or C profiles 9, 10 are welded to each other with legs facing one another with the legs of a further U or C profile 11 arranged between them, which opens towards the interior of the trench.
- This U or C profile 11 is dimensioned such that it supports the support shoes (not shown) located at the ends of the struts is able to record.
- the U or C profiles 9, 10 can be provided with notches 13 at those points where the middle U or C profile 11 has bores for receiving retaining bolts 12 for the support shoes.
- FIG. 5 to 7 show details of a plate body 2.
- This consists of a rear cover plate 23 facing the trench wall, with cross-sectionally bent or folded web members 24 made of sheet metal, which are fastened to it at a parallel distance from one another in the horizontal direction, e.g. are welded, as well as a front cover plate 25 (pointing towards the inside of the trench), which is also provided with web members 24 arranged at a parallel distance from one another.
- the web members 24 of the two plate body halves are arranged offset from one another so that they can be nested and firmly connected to one another.
- the connection is advantageously made by means of adhesive in order to largely avoid thermal tension and to ensure simpler production.
- Reinforcement tubes 27 extend perpendicular to the longitudinal axes of the web members 24, which are trapezoidal in cross section, through the plate body 2 and through the side surfaces 26 of the web members 24.
- FIG. 8 shows a cross section through part of a plate body 2, on the trench-side (outer) cover plate 23 trapezoidally folded or edged web members 24 are welded with a parallel spacing from one another and web members arranged horizontally over the cover plate 23.
- this part corresponds to the construction of the left half of the plate in Fig. 6.
- the web members 24 are arranged in such a way that the edges of the cover surfaces 28 of adjacent web members 24 are at a distance which is the same as the width of the part of the cover plate 23 which serves as the base surface 29.

Abstract
Description
Die Erfindung betrifft eine Grabenverbauvorrichtung mit Verbauplatten und Einrichtungen zur Aufnahme von zwischen zwei parallelen Verbauplatten einsetzbaren und diese auf Abstand haltenden Spreizen, wobei jede Verbauplatte durch einen Plattenkörper aus zwei parallelen Deckblechen und zwischen diesen in Längsrichtung der Verbauplatte (Grabenlängsrichtung) angeordneten Steggliedern aus Blech, welche von zu den Längsachsen der Stegglieder senkrecht angeordneten Verstärkerrohren durchzogen sind, sowie einen den Plattenkörper begrenzenden Plattenrahmen gebildet ist, welcher aus einer oberen Ambostraverse, einem unteren Abschlußprofil und seitlichen Abschlußprofilen besteht.The invention relates to a trench shoring device with shoring panels and devices for receiving spacers that can be used between two parallel shoring panels and keep them at a distance, each shoring panel being made of sheet metal by a panel body made of two parallel cover sheets and between these web members arranged in the longitudinal direction of the shoring panel (longitudinal trench direction) are penetrated by reinforcing tubes arranged perpendicular to the longitudinal axes of the web members, and a plate frame which delimits the plate body is formed, which consists of an upper Ambostraverse, a lower end profile and side end profiles.
Eine gattungsgemäße Vorrichtung ist durch die DE 29 48 458 B1 bekannt.A generic device is known from DE 29 48 458 B1.
Eine wesentliche Forderung des modernen Grabenverbaus ist es, ein möglichst kleines Grabenprofil anzustreben. Bei der bekannten Verbauvorrichtung muß deshalb ein relativ breites Grabenprofil vorgesehen werden, weil von der Innenwand der Verbauplatten vorstehende Befestigungs- und Führungsmittel das für einen einzubauenden Kanal oder eine Rohrleitung erforderliche Lumen des Grabens einengen. Ferner erfordert die Konstruktion der bekannten Verbauplatten relativ große Plattenstärken, um den statischen Anforderungen zu genügen.An essential requirement of modern trench sheeting is to strive for the smallest possible trench profile. In the known shoring device, a relatively wide trench profile must therefore be provided because the fastening and guiding means protruding from the inner wall of the shoring panels constrict the lumen of the trench required for a duct or a pipeline to be installed. Furthermore, the construction of the known shoring panels requires relatively large panel thicknesses in order to meet the static requirements.
Der Erfindung liegt die Aufgabe zugrunde, eine Grabenverbauvorrichtung zu schaffen, die so ausgebildet ist, daß sie bei geringer Wandstärke die erforderliche statische Festigkeit aufweist und zugleich die Möglichkeit bietet, die erforderliche Grabenprofilbreite gering halten zu können.The invention has for its object a trench shoring device to create, which is designed so that it has the required static strength with a small wall thickness and at the same time offers the possibility to keep the required trench profile width small.
Diese Aufgabe wird gemäß der Erfindung durch eine gattungsgemäße Grabenverbauvorrichtung mit den im kennzeichnenden Teil des Anspruchs 1 oder des Anspruches 2 genannten Merkmalen gelöst.This object is achieved according to the invention by a generic trench shoring device with the features mentioned in the characterizing part of
Eine besonders hohe Gewichtsverminderung bei ausreichenden statischen Werten ergibt sich beim Gegenstand nach dem Anspruch 2.A particularly high reduction in weight with sufficient static values results in the article according to

Die Fig. 1 und 2 zeigen eine Verbauplatte 1 für eine Grabenverbauvorrichtung nach der Erfindung. Diese Verbauplatte 1 ist als sogenannte "Schachtplatte" ausgebildet. Je zwei paarweise gegenüberstehende Schachtplatten, die durch Spreizen auf Abstand gehalten sind, bilden eine Verbauvorrichtung.1 and 2 show a
Wie die Zeichnung zeigt, besteht die Verbauplatte aus einem Plattenkörper 2, dessen Aufbau noch gesondert erläutert wird, und einem Plattenrahmen 3.As the drawing shows, the shoring plate consists of a
Der Plattenrahmen 3 wird gebildet von einem als Ambostraverse 4 ausgebildeten oberen Rahmenteil, das mit Osen 5 für den Kranangriff ausgestattet ist, einem unteren Abschlußprofil 6, an das eine Schneide 8 angesetzt sein kann, sowie seitlichen Abschlußprofilen 7, die die lotrechten Stirnseiten des Plattenkörpers 2 begrenzen.The
Wie Fig.2 zeigt, sind die seitlichen Abschlußprofile 7 als U-Profile ausgebildet, die zur Aufnahme von nicht dargestellten Stützschuhen der die Verbauplatten 1 auf Abstand haltenden Spreizen dienen. Gegenüber bisher üblichen Verbauplatten liegen diese seitlichen Abschlußprofile 7 in der allgemeinen Verbauplattenebene, so daß die von ihnen gebildete Aufnahmeschiene für die Stützschuhe nicht vor der dem Grabeninnern zugewandten Seite der Verbauplatte 1 vorstehen. Diese kann an den Stellen, wo in den seitlichen Abschlußprofilen (nicht dargestellte) Haltebolzen für Stützschuhe der Spreizen vorgesehen sind, Ausklinkungen 13 aufweisen.As FIG. 2 shows, the
Wie in den Fig. 3 und 4 gezelgt, kann das seitliche Abschlußprofil 7 auch aus drei miteinander verschweißten U- oder C-Profilen bestehen. Dabei sind zwei U- bzw. C-Profile 9,10 mit einander zugewandten Schenkeln mit den Schenkeln eines dazwischen angeordneten weiteren U- bzw.C-Profiles 11 verschweißt, welches sich zum Grabeninnern hin öffnet. Dieses U- bzw. C-Profil 11 ist so bemessen, daß es die an den Enden der Spreizen befindlichen, (nicht dargestellten) Stützschuhe formschlüssig aufzunehmen vermag.As shown in Figs. 3 and 4, the
Wie Fig.4 zeigt, können die U- bzw. C-Profile 9,10 an denjenigen Stellen, wo das mittlere U- bzw. C-Profil 11 Bohrungen zur Aufnahme von Haltebolzen 12 für die Stützschuhe aufweist, mit Ausklinkungen 13 versehen sein.As FIG. 4 shows, the U or
Die Fig.5 bis 7 zeigen Einzelheiten eines Plattenkörpers 2. Dieser besteht aus einem rückwärtigen, der Grabenwand zugewandten Deckblech 23, mit im Querschnitt trapezförmig abgekanteten oder gefalteten Steggliedern 24 aus Blech, die im parallelen Abstand zueinander in waagerechter Richtung daran befestigt, z.B. angeschweißt sind, sowie einem vorderen (zum Grabeninnern weisenden) Deckblech 25, das ebenfalls mit in parallelem Abstand zueinander angeordneten Steggliedern 24 versehen ist. Die Stegglieder 24 der beiden Plattenkörperhälften sind so zueinander versetzt angeordnet, daß sie ineinandergesetzt und miteinander fest verbunden werden können. Die Verbindung erfolgt vorteilhaft mittels Kleber, um thermische Verspannungen weitgehend zu vermeiden und eine einfachere Fertigung sicher zu stellen. Senkrecht zu den Längsachsen der im Querschnitt trapezförmig ausgebildeten Stegglieder 24 erstrecken sich durch den Plattenkörper 2 und durch die Seitenflächen 26 der Stegglieder 24 Verstärkungsrohre 27.5 to 7 show details of a
Diese Konstruktion ermöglicht eine einfache und preiswerte Fertigung und führt zu Verbauplatten, deren statische Werte diejenigen bekannter vergleichbarer Verbauplatten um ein mehrfaches übertreffen.This construction enables simple and inexpensive production and leads to shoring panels, the static values of which exceed those of known comparable shoring panels by a multiple.
Dies wiederum eröffnet die Möglichkeit, die Abmessungen der Verbauplatten und damit deren Gewicht beträchtlich zu verringern, was wiederum den Vorteil erbringt, mit einer LKW-Ladung mehr Verbaumaterial transportieren zu können. Zugleich wird insbesondere auch die Forderung erfüllt, die erforderlichen Grabenprofile verkleinern zu könnenThis in turn opens up the possibility of considerably reducing the dimensions of the shoring panels and thus their weight, which in turn has the advantage of being able to transport more shoring material with a truck load. At the same time in particular also fulfilled the requirement to be able to reduce the required trench profiles
Eine einfachere und ebenfalls feste und vorteilhafte Ausführungsform eines Plattenkörpers 2 ist in Fig.8 dargestellt. Die Fig.8 zeigt einen Querschnitt durch einen Teil eines Plattenkörpers 2, auf dessen grabenseitigem (äußerem) Deckblech 23 im Querschnitt trapezförmig gefaltete oder gekantete Stegglieder 24 mit parallelem Abstand zueinander und waagerecht über das Deckblech 23 angeordnete Stegglieder angeschweißt sind. Insoweit entspricht dieser Teil der Konstruktion der linken Plattenhälfte in Fig.6. Die Stegglieder 24 sind so zueinander angeordnet, daß die Kanten der Deckflächen 28 benachbarter Stegglieder 24 einen Abstand aufweisen, der der Breite des als Basisfläche 29 dienenden Teiles des Deckbleches 23 gleich ist. Diese Kanten sind durch angeschweißte Blechplatten 30 miteinander verbunden, die mit den Deckflächen 28 der Stegglieder 24 das innere Deckblech 25 der Konstruktion nach den Fig. 8-10 ersetzen. Durch die Stegglieder 24 erstrecken sich, wie bei den anderen Konstruktionen die Verstärkungsrohre 27.A simpler and also firm and advantageous embodiment of a
Durch diese Ausführungsform wird eine enorme Gewichtsersparnis erzielt. Darüber hinaus werden Einpassungsschwierigkeiten erspart, die beim Zusammenfügen der Plattenhälften nach den Fig. 5 bis 7 nicht immer auszuschließen sind.An enormous weight saving is achieved by this embodiment. In addition, fitting difficulties are spared, which cannot always be ruled out when joining the plate halves according to FIGS. 5 to 7.
