Description

Die Erfindung betrifft eine Verbaubox zum Verbau von Gräben mit zwei in Grabenlängsrichtung im Abstand zueinander ausrichtbaren Verbauplatten sowie einer auf den oberen Rand jeder Verbauplatte aufsetzbaren Aufstockplatte.The invention relates to a Verbaubox for the installation of trenches with two in trench longitudinal direction at a distance alignable shoring plates and an attachable to the upper edge of each shoring Aufstockplatte.

Im so genannten Boxenverbau werden an gegenüberliegenden Grabenwänden Verbauplatten von üblicherweise vier Spreizen auf Abstand gehalten. An den auch als Pfosten bezeichneten, randseitig an den Verbauplatten angeordneten Profilen sind die Spreizen, auch als Spindeln bezeichnet, um eine horizontale, parallel zur Plattenebene verlaufende Achse eines Bolzens schwenkbar gelagert. Die schwenkbare Lagerung ermöglicht es, die beiden gegenüberstehenden Verbauplatten, die an ihren unteren Rändern regelmäßig Schneidkanten aufweisen, abwechselnd in Richtung der Grabensohle voranzutreiben oder diese aus dem Graben heraus zu ziehen. Die gegenüberliegenden Verbauplatten weisen beispielsweise eine Plattenhöhe von 2,40 Metern und Plattenlängen zwischen 2,00 bis 5,00 Metern auf.In the so-called pit lining, lining panels of usually four spreaders are kept at a distance on opposite trench walls. At the edges also referred to as posts, arranged on the shoring plates profiles the spreaders, also referred to as spindles, about a horizontal, parallel to the plane of the plate axis of a bolt pivotally mounted. The pivotal mounting makes it possible to advance the two opposing shoring plates, which regularly have cutting edges at their lower edges, to advance alternately in the direction of the trench sole or to pull them out of the trench. For example, the opposite lining panels have a panel height of 2.40 meters and panel lengths of 2.00 to 5.00 meters.

Um Gräben mit größerer Grabentiefe verbauen zu können, können auf den oberen Rand jeder Verbauplatte Aufstockplatten aufgesetzt werden, die üblicherweise eine Höhe von 1,40 Metern und eine der darunter liegenden Verbauplatte entsprechende Länge aufweisen. An den äußeren seitlichen Rändern der Aufstockplatten sind ebenfalls Pfosten angeordnet, die von mindestens einer Spreize bzw. Spindel auf Abstand gehalten werden. Eine derartige Verbaubox ist aus dem Verkaufsprospekt 2009 "STANDARD-BOX" der Anmelderin bekannt.In order to install trenches with greater trench depth, Aufstockplatten can be placed on the upper edge of each Verbauplatte, which usually have a height of 1.40 meters and one of the underlying Verbauplatte corresponding length. At the outer lateral edges of the Aufstockplatten posts are also arranged, which are held by at least one spreader or spindle at a distance. Such a Verbaubox is known from the sales prospectus 2009 "STANDARD BOX" the applicant.

Bei derartigen Verbauboxen ist die Rohrdurchlasshöhe unterhalb der tiefsten Spreize eingeschränkt. Des Weiteren kann das Einbringen längerer Rohre bzw. Bauteile in den Graben durch die randseitig jeder Verbaubox übereinander angeordneten Spreizen erheblich erschwert oder sogar, je nach Anordnung der Spreizen und Tiefe des Grabens, unmöglich sein.In such Verbauboxen the pipe passage height is limited below the deepest spreader. Furthermore, the introduction of longer pipes or components in the trench by the edge of each Verbaubaubpunkt one above the other arranged spreaders considerably more difficult or even, depending on the arrangement of the spars and depth of the trench, be impossible.

Aus dem Verkaufsprospekt 2009 der Anmelderin "ROLLENSCHLITTENBOX 780er SERIE" sind Verbauboxen bekannt, die höhere Rohrdurchlässe ermöglichen. Zwischen zwei randseitig fest auf der Oberfläche der sich gegenüberstehenden Verbauplatten angeordneten Führungen ist ein Rollenschlitten vertikal verschiebbar angeordnet. Ein derartiger Rollenschlitten, allerdings für eine Verbauvorrichtung mit Doppelgleitschiene, ist beispielsweise in der DE 297 031 90 U1 beschrieben. Die Verbauplatten derartiger Rollenschlitten-Verbauboxen weisen eine Höhe von 3,15 bis 4,00 Metern auf, wobei sich der Rohrdurchlass bis zu einer Höhe von 2,78 Meter über der Grabensohle stufenlos mit Hilfe des Rollenschlittens einstellen lässt. Aufgrund ihrer Größe lassen sich Rollenschlitten-Verbauboxen lediglich als Sondertransport zur Baustelle transportieren.From the sales prospectus 2009 of the applicant "ROLLENSCHLITTENBOX 780er SERIE" Verbauboxen are known that allow higher pipe passages. Between two edge fixed on the surface of the opposing sheathing plates arranged guides a roller carriage is arranged vertically displaceable. Such a roller carriage, however, for a Verbauvorrichtung with double slide, is for example in the DE 297 031 90 U1 described. The shoring plates of such Rollenschlitten Verbauboxen have a height of 3.15 to 4.00 meters, with the pipe passage can be adjusted up to a height of 2.78 meters above the grave sole steplessly using the roller carriage. Due to their size, roller carriage boxes can only be transported as special transport to the construction site.

Ausgehend von einer Verbaubox der eingangs erwähnten Art liegt der Erfindung die Aufgabe zu Grunde, insbesondere unter Verwendung bereits vorhandener Standard-Verbauboxen größere Durchlasshöhen zu erzielen und das Einbringen längerer Rohre bzw. Gegenstände in den Graben zu erleichtern. Zur Lösung der Aufgabe soll ein Rückgriff auf Sonderverbauelemente, wie z.B. die Rollenschlittenbox, nicht erforderlich sein. Insbesondere sollen kostenträchtige und zeitraubende Sondertransporte zur Baustelle vermieden werden.Based on a Verbaubox of the type mentioned above, the invention is based on the object, in particular using existing standard Verbauboxen to achieve greater passage heights and to facilitate the introduction of longer pipes or objects in the trench. To achieve the object of a recourse to Sonderverbauelemente such. the Rollenschlittenbox, not required. In particular, costly and time-consuming special transports are to be avoided to the site.

Diese Aufgabe wird bei einer Verbaubox der eingangs erwähnten Art dadurch gelöst, dass an der Oberfläche jeder Grundplatte und der Oberfläche der aufgesetzten Aufstockplatte randseitig zwei vertikal verlaufende, die Grundplatte und die Aufstockplatte überspannende Verbindungsprofile lösbar befestigt sind, dass zwei vertikal zwischen jeweils zwei Führungen verschiebbare Spreizrahmen die gegenüberliegenden Verbauplatten und Aufstockplatten auf Abstand halten und dass an der dem Graben zugewanden Seite jedes Verbindungsprofils eine der beiden Führungen für den Spreizrahmen angeordnet ist, die sich in vertikaler Richtung sowohl über die Grundals auch die Aufstockplatte erstreckt.This object is achieved in a Verbaubox of the type mentioned in that on the surface of each base plate and the surface of the attached Aufstockplatte edge two vertically extending, the base plate and the extension plate spanning connection profiles are releasably secured, that two vertically displaceable between two guides each spreading frame the opposite Keep lining plates and extension plates at a distance and that on the side facing the trench side of each connection profile one of the two guides for the expansion frame is arranged, which extends in the vertical direction over both the base and the extension plate.

Die Verwendung der Verbindungsprofile erlaubt es, die Verbauplatten und Aufstockplatten als Einzelteile zur Baustelle zu transportieren und erst dort zusammen zu setzen.The use of the connection profiles makes it possible to transport the shoring panels and countertops as individual parts to the construction site and to put them together there.

Der vertikal zwischen den Führungen verschiebbare Spreizrahmen ermöglicht erheblich höhere Durchlasshöhen als bei herkömmlichen Verbauboxen mit Aufstockplatten, die durch mindestens drei Spreizen auf Abstand gehalten werden.The vertically movable between the guides Spreizrahmen allows significantly higher passage heights than conventional Verbauboxen with Aufstockplatten, which are held by at least three spreaders at a distance.

Der Spreizrahmen besitzt vertikale Rahmenseitenabschnitte, die lediglich mittels einer Querstrebe miteinander verbunden sind. Zur Realisierung großer Durchlasshöhen wird der Spreizrahmen in die obere Position zwischen den beiden Führungen verschoben. Da sich jede Führung für den Spreizrahmen an einem der Verbindungsprofile befindet, dass sich in vertikaler Richtung sowohl über die Grund- als auch die Aufstockplatte erstreckt, befindet sich die Querstrebe des Spreizrahmens in der oberen Position etwa in Höhe der Aufstockplatte. Im Bereich der darunter liegenden Grundplatte befinden sich keinerlei Queraussteifungen, die die Durchlasshöhe einschränken. Zum Einschwenken besonders langer Rohre in eine Verbaubox können einzelne Spreizrahmen in benachbarten Verbauboxen gezielt abgesenkt bzw. angehoben werden.The Spreizrahmen has vertical frame side portions which are interconnected only by means of a transverse strut. To realize high passage heights of the expansion frame is moved to the upper position between the two guides. Since each guide for the Spreizrahmen is located on one of the connecting profiles that extends in the vertical direction on both the base and the Aufstockplatte, the cross member of the Spreizrahmens in the upper position is approximately equal to the Aufstockplatte. In the area of the underlying base plate, there are no transverse stiffeners, which limit the passage height. For swinging particularly long pipes in a Verbaubox individual Spreizrahmen can be selectively lowered or raised in adjacent Verbauboxen.

Auf den Grund- und Aufstockplatten herkömmlicher Standard-Verbauboxen sind wandseitig als C-Profile ausgestaltete Pfosten angeordnet, die in Grabenlängsrichtung verlaufende Durchgänge zur Aufnahme von Bolzen für die schwenkbare Lagerung der Spreizen bzw. Spindeln aufweisen. Vorzugsweise werden die Pfosten an den Grund- und Aufstockplatten dazu benutzt, um daran das die Grund- und Aufstockplatte überspannende Verbindungsprofil lösbar zu befestigen. Hierzu umgreift das Verbindungsprofil jeweils zwei fluchtend zueinander ausgerichtete Pfosten von Grund- und Aufstockplatte und wird mit diesen verbolzt. Das Verbindungsprofil ist zu diesem Zweck beispielsweise als U-Profil ausgebildet, dessen freie Schenkel seitlich an den freien Schenkeln des Pfostens zur Anlage gelangen. Zur Herstellung der Verbolzung sind in dem Verbindungsprofil mit den Durchgängen in den Pfosten korrespondierende Durchgänge angeordnet.On the ground and top floors of conventional standard junction boxes, posts configured as C-profiles are arranged on the wall side and have passages extending in the trench longitudinal direction for receiving bolts for the pivotable mounting of the spreaders or spindles. Preferably the posts on the ground and top plates are used to releasably attach thereto the connecting and spanning plate spanning connection profile. For this purpose, the connection profile encompasses two aligned in each case posts of ground and Aufstockplatte and is bolted to them. The connection profile is formed for this purpose, for example, as a U-profile, the free legs reach the side of the free legs of the post to the plant. For the production of the Verbolzung corresponding passageways are arranged in the connection profile with the passages in the post.

Um eine Verbaubox zu schaffen, die unempfindlicher gegen Verschmutzungen der Führungen der Spreizrahmen ist und einen verklemmungsfreien Ein- und Rückbau ermöglicht, ist es in einer Ausgestaltung der Erfindung vorgesehen, dass an den vertikalen Rahmenseitenabschnitten jeweils mindestens zwei Rollen angeordnet sind, dass jede Führung als eine mit ihrer Oberfläche dem Inneren des Grabens zugewandte Führungsplatte ausgestaltet ist, auf der die Rollen des Spreizrahmens abrollen und dass die Führungsplatte in Grabenlängsrichtung freie Seitenabschnitte aufweist, die an den vertikalen Rahmenseitenabschnitten angeordnete Führungsmittel hintergreifen. Das Führungsmittel hält die Rollen des Spreizrahmens auf der ebenen Rollbahn und überträgt ggf. auftretende Zugkräfte zwischen dem Spreizrahmen und den Platten der Verbaubox.In order to create a Verbaubox that is less sensitive to contamination of the guides of the Spreizrahmen and a jam-free installation and removal allows, it is provided in one embodiment of the invention that at least two roles are arranged on the vertical frame side sections that each guide as a with its surface towards the interior of the trench facing guide plate is configured, on which roll the rollers of the Spreizrahmens and that the guide plate in trench longitudinal direction has free side portions which engage behind the vertical frame side portions arranged guide means. The guide means holds the rollers of the Spreizrahmens on the flat runway and transmits any tensile forces between the Spreizrahmen and the plates of Verbaubox.

Ein konstruktiv einfaches Führungsmittel besteht aus an den vertikalen Rahmenseitenabschnitten des Spreizrahmens befestigten Winkelprofilen, deren freie Schenkel die freien Seitenabschnitte der Führungsplatte hintergreifen.A structurally simple guide means consists of attached to the vertical frame side portions of the Spreizrahmens angle profiles, the free legs engage behind the free side portions of the guide plate.

Üblicherweise ist die Querstrebe zwischen den vertikalen Rahmenseitenabschnitten mittig angeordnet. Ein solcher im wesentlichen H-förmiger Spreizrahmen erleichtert die Arbeit im Graben, da die in Grabenlängsrichtung störenden Einbauten reduziert sind. Ist bereits ein Rohr auf der Grabensohle verlegt, lässt sich der H-förmige Spreizrahmen tiefer absenken, als ein Spreizrahmen, der beispielsweise eine obere und eine untere Querstrebe aufweist.Usually, the cross brace is arranged centrally between the vertical frame side sections. Such in the essential H-shaped Spreizrahmen facilitates work in the trench, since the disturbing in trench longitudinal internals are reduced. If a pipe has already been laid on the trench bottom, the H-shaped spreader frame can be lowered lower than a spreader frame which has, for example, an upper and a lower transverse strut.

Noch größere Durchlasshöhen lassen sich erreichen, wenn die Querstrebe außermittig zwischen den vertikalen Rahmenseitenabschnitten im oberen Bereich angeordnet ist.Even greater passage heights can be achieved if the transverse strut is arranged off-center between the vertical frame side sections in the upper area.

Um den Spreizrahmen an unterschiedlich breite Gräben anpassen zu können, ist die Querstrebe in einer bevorzugten Ausgestaltung der Erfindung längenveränderlich. Die Längenveränderlichkeit lässt sich insbesondere dadurch erreichen, dass die Querstrebe mehrteilig ausgeführt ist und die Teile über Flansche miteinander verbunden sind. Zwischen den Flanschen lassen sich unterschiedlich lange Zwischenstücke einsetzen.In order to adapt the Spreizrahmen to different width trenches, the cross member is variable in length in a preferred embodiment of the invention. The Längenveränderlichkeit can be achieved in particular by the fact that the cross member is made of several parts and the parts are connected to each other via flanges. Intermediate pieces of different lengths can be inserted between the flanges.

Die Verbaubox (1) umfasst zwei in Grabenlängsrichtung (2) im Abstand der Breite des Grabens zueinander ausgerichtete Verbauplatten (3, 4) auf deren oberen Rändern jeweils eine Aufstockplatte (5, 6) aufgesetzt ist.The Verbaubox (1) comprises two in Grabenlängsrichtung (2) at a distance from the width of the trench aligned Verbauplatten (3, 4) on the upper edges of each a Aufstockplatte (5, 6) is placed.

An den äußeren, seitlichen Rändern jeder Verbauplatte (3, 4) sind vertikal verlaufende, als Pfosten ausgebildete Profile (7, 8) angeschweißt. An der Oberfläche der aufgesetzten Aufstockplatte (5, 6) sind ebenfalls an den beiden seitlichen Rändern jeweils ein als Pfosten ausgebildetes Profil (9, 10) aufgeschweißt. Jeweils zwei fluchtend zueinander ausgerichtete Profile (7, 9) bzw. (8, 10) umgreift ein im Querschnitt U-förmiges Verbindungsprofil (11,12). Das Verbindungsprofil (11,12) greift über die Profile (7, 9 bzw. 8, 10) von Verbau- und Aufstockplatte (3,5 bzw. 4,6) und wird mit je zwei Bolzen (13) in jedem der beiden Profile (7,9 bzw. 8, 10) abgesteckt. Zur Befestigung des Verbindungsprofils (11,12) an den C-förmig profilierten Pfosten weisen deren freie seitliche Schenkel Durchgänge (14, 15) auf, die mit entsprechenden Durchgängen in den Pfosten (7, 9 bzw. 8, 10) korrespondieren.At the outer, lateral edges of each Verbauplatte (3, 4) are vertically extending, designed as a post profiles (7, 8) welded. On the surface of the patch plate (5, 6) are also on the two lateral edges each formed as a post profile (9, 10) welded. Respectively two aligned profiles (7, 9) and (8, 10) surrounds a cross-sectionally U-shaped connecting profile (11,12). The connecting profile (11,12) engages over the profiles (7, 9 or 8, 10) of shoring and Aufstockplatte (3,5 or 4,6) and is provided with two bolts (13) in each of the two profiles (7.9 or 8, 10) staked. For attachment of the connection profile (11,12) to the C-shaped profiled post their free lateral legs have passages (14, 15) which correspond with corresponding passages in the posts (7, 9 and 8, 10).

Die gegenüberliegenden Verbauplatten (3, 4) und Aufstockplatten (5, 6) werden von zwei vertikal zwischen jeweils zwei Führungen verschiebbaren Spreizrahmen (16, 17) auf Abstand gehalten. An der dem Graben zugewandten Seite jedes Verbindungsprofils (11, 12) ist eine der beiden Führungen für den Spreizrahmen (16, 17) angeordnet, die sich in vertikaler Richtung sowohl über die Grundplatte (3, 4) als auch die Aufstockplatte (5, 6) erstreckt. Die Führung an jedem Verbindungsprofil (11, 12) ist als eine mit ihrer Oberfläche dem inneren des Grabens zugewandte Führungsplatte (18, 19) ausgestaltet.The opposite Verbauplatten (3, 4) and Aufstockplatten (5, 6) are held by two vertically displaceable between each two guides Spreizrahmen (16, 17) at a distance. On the side of each trench profile (11, 12) facing the trench, one of the two guides for the spreader frame (16, 17) is arranged, which extends vertically over both the base plate (3, 4) and the top plate (5, 6) ). The guide on each connecting profile (11, 12) is designed as a with its surface facing the inner of the trench guide plate (18, 19).

Jeder längs der Führung vertikal bewegbare Spreizrahmen (16, 17) besitzt vertikale Rahmenseitenabschnitte (20, 21), die mittels einer mehrteiligen Querstrebe (22) miteinander verbunden sind. An den vertikalen Rahmenseitenabschnitten (20, 21) sind jeweils zwei Rollen angeordnet, die auf der Führungsplatte (18, 19) abrollen.Each along the guide vertically movable expansion frame (16, 17) has vertical frame side portions (20, 21) which are interconnected by means of a multi-part transverse strut (22). On the vertical frame side portions (20, 21), two rollers are arranged in each case, which roll on the guide plate (18, 19).

Die Führungsplatte (18, 19)weist, wie insbesondere aus den Figuren 3 und 4 ersichtlich, freie Seitenabschnitte (23, 24) auf, die an den vertikalen Rahmenseitenabschnitten (20, 21) des Spreizrahmens (16,17) angeordnete Führungsmittel (25, 26) hintergreifen.The guide plate (18, 19) has, as in particular from the FIGS. 3 and 4 can be seen, free side portions (23, 24), which engage behind the vertical frame side portions (20, 21) of the Spreizrahmens (16,17) arranged guide means (25, 26).

Um die Spreizrahmen (16, 17) an unterschiedliche Grabenbreiten anpassen zu können, sind die Teile der Querstrebe (22) mittels übereinstimmender Flansche (27 bis 29) untereinander verbunden. Durch Entfernen von Teilen der Querstrebe (22) bzw. Einfügen von Zwischenstücken kann die Länge variiert werden.In order to be able to adapt the expansion frames (16, 17) to different trench widths, the parts of the transverse strut (22) are interconnected by means of matching flanges (27 to 29). By removing parts of the transverse strut (22) or inserting intermediate pieces, the length can be varied.

Das Ausführungsbeispiel nach Figur 6 entspricht weitgehend der Verbaubox (1) nach den Figuren 1 bis 5. Unterschiede ergeben sich lediglich hinsichtlich des Spreizrahmens (30), bei dem die Querstrebe (31) zwischen den Rahmenseitenabschnitten (32, 33) außermittig, nämlich an deren bezogen auf die Grabensohle (40) oberen Rand angeordnet sind. Hierdurch lassen sich noch größere Rohrdurchlasshöhen als bei einem H-förmigen Spreizrahmen, wie er in den Figuren 1 bis 5 dargestellt ist, erzielen.The embodiment according to FIG. 6 corresponds largely to the Verbaubox (1) after the FIGS. 1 to 5 , Differences arise only with respect to the Spreizrahmens (30), in which the transverse strut (31) between the Frame side sections (32, 33) off-center, namely, are arranged at the upper edge relative to the trench sole (40). As a result, even greater pipe outlet heights than in an H-shaped expansion frame, as in the FIGS. 1 to 5 is achieved achieve.

Figur 5 veranschaulicht das Einbringen eines überlangen Rohres (38) in einen Graben mit drei hintereinander angeordneten Verbauboxen (1). Das überlange Rohr (38) soll in der Verbaubox (1) in der vorderen Position (35) unterhalb der Querstrebe (22) des Spreizrahmens (17) eingebracht werden. Zu diesem Zweck werden in Bezug auf die Einschwenkrichtung (39) der hintere Spreizrahmen (17) der Verbaubox (1) an der mittleren Position (36) sowie der vordere Spreizrahmen (16) der Verbaubox an der Position (37) vollständig abgesenkt, während der Spreizrahmen (16) der Verbaubox (1) in der mittleren Position (36) angehoben wird. FIG. 5 illustrates the introduction of an overlong pipe (38) in a trench with three successively arranged Verbugoxen (1). The overlong tube (38) is intended to be introduced into the junction box (1) in the front position (35) below the transverse strut (22) of the expansion frame (17). For this purpose, with respect to the Einschwenkrichtung (39) of the rear Spreizrahmen (17) of the Verbaubox (1) at the middle position (36) and the front Spreizrahmen (16) of the Verbaubox at the position (37) completely lowered while the Spreizrahmen (16) of the Verbaubox (1) in the middle position (36) is raised.

Das Rohr (38) lässt sich nun ohne Behinderung durch Querstreben (22) im Bereich der Verbauboxen (1) an den Positionen (36, 37) absenken und in Einschwenkrichtung (39) nach vorne unter den angehobenen Spreizrahmen (17, 16) der Verbauboxen (1) in den Positionen (35, 36) hindurchbewegen, bis dieses auf der Grabensohle (40) aufliegt.The tube (38) can now be lowered without hindrance by transverse struts (22) in the region of the Verbauboxen (1) at the positions (36, 37) and in Einschwenkrichtung (39) forward under the raised Spreizrahmen (17, 16) of the Verbbauoxen (1) in the positions (35, 36), until it rests on the trench sole (40).

Dieses Einschwenken von überlangen Rohren bei gleichzeitig deutlich vergrößerter Durchlasshöhe gegenüber herkömmlichen Verbauboxen unter Verwendung von deren Platten ist aufgrund der erfindungsgemäßen Verbindungsprofile, die zugleich als Führung für einen Spreizrahmen dienen, möglich.
