Abstract
Description
Die Erfindung betrifft eine Verbauplatte, bestehend aus zwischen zwei rechteckigen Deckblechen eingeschlossenen Profilblechelementen und umlaufenden, mit den Deckblechen verschweißten Hohlprofilen, zum Einsatz bei der Grabenverschalung im Tiefbau.The invention relates to a shoring panel consisting of between two rectangular cover plates enclosed profile sheet elements and all-round, welded to the cover plates Hollow profiles, for use in trench formwork in civil engineering.
Eine Verbauplatte mit umlaufendem Hohlprofil wird in DE 30 15 110 A1 beschrieben. Diese ebenfalls zum Abstützen von Grabenwänden vorgesehene Verbauplatte besitzt sich im wesentlichen über die gesamte Plattenfläche erstreckende Außenbleche, einen rechteckigen, die Ränder des Außenblechs abstützenden Rahmen und den Rahmen versteifende, einander kreuzende Profile. Die Rahmenprofile bilden zusammen mit den Außenblechen geschlossene Kastenhohlprofile, also einen den Plattenkörper begrenzenden Plattenrahmen. Dieser kann im einzelnen bestehen aus einer oberen Amboßtraverse (Druckholm), auf die bei Betrieb mit der Baggerschaufel gedrückt oder geschlagen wird; aus Seitenabschlußprofilen (Vertikalholm), die ebenso wie die Amboßprofile Rechteckquerschnitt besitzen können; und aus einem unteren Spitz- oder Schneidenprofil mit Dreieck-Querschnitt. Eine solche Verbauplatte wird auch in US-A-40 56 938 angegeben.A shoring panel with a circumferential hollow profile is described in DE 30 15 110 A1. This also for supporting trench walls The provided shoring plate has essentially outer sheets extending over the entire plate area, one rectangular frame supporting the edges of the outer sheet and profiles stiffening and crossing each other. The Frame profiles form closed together with the outer sheets Hollow box sections, that is, one that delimits the panel body Plate frame. This can consist of one upper anvil crossbar (pressure beam), to which when operating with the Excavator shovel is pushed or hit; from side end profiles (Vertical spar), which is just like the anvil profiles Can have a rectangular cross-section; and from a lower one Pointed or cutting profile with triangular cross-section. Such Sheeting board is also given in US-A-40 56 938.
Bei der Montage einer Verbaubox aus zwei Verbauplatten wird im allgemeinen die eine Verbauplatte auf den Boden gelegt, daraufhin werden Spreizen (das sind Abstandhalter zwischen im Graben gegenüberstehenden Verbauplatten) in der auf dem Boden liegenden Platte befestigt; die zweite Platte wird dann mit einem Kran über die erste Platte gehoben und die Spreizen werden von unten in die zweite Platte eingesetzt und dort befestigt. Bei dieser Arbeit muß die zweite Platte exakt mit dem Kran dirigierbar sein und sicher gehalten werden, damit Unfälle nicht auftreten können. Außerdem erleichtert es den Zusammbau wesentlich, wenn die Platten waagerecht hängen, da es beim Einführen der Spindel zu keinem Verkanten kommt. Zu diesem Zweck werden in der Praxis die äußeren Schmalseiten der beiden Seitenabschlußprofile der Platte bis etwa zur Spitze der Schneide des unteren Hohlprofils als "freie" Dreieckblechlaschen vorgezogen und mit einem Einhängeloch ausgestattet. Beim waagerechten Dirigieren kann der Kran an den beiden Dreiecklaschen und weiteren der Plattenoberkante zugeordneten Anschlagpunkten, also an vier Punkten, angreifen.When installing a shoring box made of two shoring panels, the general which put a shoring plate on the floor, then are spreading (these are spacers between the Trench facing sheeting panels) in the on the ground attached lying plate; the second plate is then with a crane is lifted over the first plate and the spreaders are inserted into the second plate from below and fastened there. In this work, the second plate must match exactly Crane can be directed and kept safe to prevent accidents cannot occur. It also makes assembly easier essential if the plates hang horizontally, as it is at Inserting the spindle does not result in tilting. To this The outer narrow sides of the two are used in practice Side end profiles of the plate to about the top of the Cut the lower hollow profile as "free" triangular sheet metal tabs brought forward and equipped with a hanging hole. When conducting horizontally, the crane can use the two triangle tabs and other attachment points assigned to the top edge of the panel, attack at four points.
Die seitlich an den Längsenden der Schneide vorgesehenen, durchbohrten Laschen werden im allgemeinen nach kurzer Benutzungszeit verbogen oder sogar abgebrochen. In der Praxis wird daher die Verbauplatte beim Montieren an der Schneide gehalten, indem - ohne besonderen Anschlagpunkt - die Kranhaken einfach über die Schneide gehängt werden. Es besteht dann immer die Gefahr, daß der eine oder andere Haken bei angehobener Platte seitlich verrutscht, so daß die ganze Platte ins Kippen kommt.The side provided on the longitudinal ends of the cutting edge, Pierced tabs are generally used after a short period of use bent or even broken off. In practice therefore the shoring plate is held on the cutting edge during assembly, by - without a special attachment point - the crane hook just be hung over the cutting edge. Then it always exists the risk that one or the other hook when raised The plate slips sideways so that the whole plate tilts is coming.
Der Erfindung liegt die Aufgabe zugrunde, an der Spitze bzw. Unterkante oder Schneide der Verbauplatte eine Befestigungsmöglichkeit als Anschlagmittel für einen Kranhaken, ein Seil oder dergleichen, insbesondere zum Aufhängen der Verbauplatte in einer waagerechten Lage, zu schaffen, durch die weder das Eintreiben der Verbauplatte in den Boden behindert noch die als Hohlprofil ausgebildete Schneide der Verbauplatte gegenüber Biegeknickung oder dergleichen geschwächt wird und die selbst durch das Eintreiben der Verbauplatte in den Boden oder das Weiterziehen der Verbauplatte längs des Grabens nicht beschädigt werden kann. Außerdem soll das neue Befestigungs-bzw. Anschlagmittel ähnlich wie die früheren, an den Längsenden der Schneide vorgesehenen Dreiecklaschen das unmittelbare Einhängen eines Kranhakens erlauben. The invention has for its object at the top or Bottom edge or cutting edge of the shoring plate can be attached as a sling for a crane hook, a rope or the like, especially for hanging the shoring panel in a horizontal position, through which neither Driving the shoring plate into the ground still hinders the cutting edge designed as a hollow profile opposite the sheeting panel Bending buckling or the like is weakened and the even by driving the sheeting into the ground or moving the lining plate along the trench is not damaged can be. In addition, the new fastening or. Slings similar to the previous ones, on the long ends the edge provided triangular tabs the immediate Allow hooking in of a crane hook.
Die erfindungsgemäße Lösung wird im Anspruch 1 angegeben. Verbesserungen und weitere Ausgestaltungen der Erfindung werden in den Unteransprüchen beschrieben.The solution according to the invention is specified in claim 1. Improvements and further embodiments of the invention described in the subclaims.
Nach der Erfindung enthält bei der eingangs genannten Verbauplatte das die Schneide der Plattenunterkante bildende Spitz-Hohlprofil mindestens einen massiven aus Stahl bestehenden Aufhängering mit einem zum dreieckigen Querschnitt der Schneide zumindest annähernd deckungsgleichen Querschnitt und mit zum Teil geradem sowie im übrigen etwa halbrundem Außenumfang, dessen gerundeter Bereich rundum mit dem Spitz-Hohlprofil verschweißt ist und dessen gerader Bereich einen Teil der Plattenunterkante bildet.According to the invention contains in the shoring plate mentioned above the pointed hollow profile forming the cutting edge of the lower edge of the board at least one massive steel one Hanging ring with a triangular cross-section of the cutting edge at least approximately congruent cross-section and with partly straight as well as approximately semicircular outer circumference, its rounded Area is welded all around with the pointed hollow profile and whose straight area forms part of the lower edge of the plate.
Erfindungsgemäß wird also in die als Hohlprofil ausgebildete Spitze bzw. Schneide der Verbauplatte ein - bevorzugt aus Stahlguß oder Schmiedestahl bestehender - massiver Ring eingesetzt, dessen Außenkontur einerseits genau in die Fläche der den Ring umgebenden Deckflächen paßt und andererseits einen Teil der Schneide sowie deren Kante selbst bildet.According to the invention it is designed as a hollow profile Tip or cutting edge of the shoring plate in - preferably out Cast steel or forged steel existing - solid ring used, the outer contour of the one hand exactly in the area of the the ring surrounding cover surfaces fits and on the other hand one Forms part of the cutting edge and its edge itself.
Der erfindungsgemäße Aufhängering befindet sich innerhalb des die Verbauplatte versteifenden Hohlprofil-Rahmens, der Ring schwächt jedoch den Rahmen nicht, da seine wegen der massiven Ausführung Eigensteifheit mindestens so groß ist, wie die Steifheit des zum Einsetzen des Rings aus dem Hohlprofil auszuschneidenden Stahlblechs, und da er durch das Rundum-Verschweißen mit den verbleibenden Hohlprofil-Teilen zu einem Teil des Hohlprofils wird.The hanging ring according to the invention is located within the the shoring stiffening hollow profile frame, the ring however, does not weaken the frame because its because of the massive Execution inherent stiffness is at least as great as that Stiffness of the part to be cut out of the hollow profile for inserting the ring Steel sheet, and since it is by all-round welding with the remaining hollow profile parts into one Becomes part of the hollow profile.
Ein wesentlicher Vorteil des erfindungsgemäßen Aufhängerings besteht darin, daß das Ringloch so nahe an der Schneide liegen kann, daß ein Kranhaken - gegebenenfalls mit seiner Hakensicherung - über den zwischen Schneide und Loch verbleibenden Steg greifen kann. Dadurch wird für eventuelle Montagearbeiten, z.B. bei einer Verbaubox, eine maximale Sicherheit geschaffen.A major advantage of the hanging ring according to the invention is that the ring hole is so close to the cutting edge can that a crane hook - if necessary with its hook safety device - over the remaining between the cutting edge and the hole Can grab the web. This will allow for any assembly work e.g. with a shoring box, maximum security is created.
Ein damit verbundener Vorteil der erfindungsgemäßen Lösung besteht darin, daß der in die Schneide eingebaute Aufhängering, den beim Eintreiben in den Boden wirkenden Kräften wegen der Eigenstabilität mindestens ebenso gut wie die übrigen Teile der Schneide widerstehen kann und daß der Aufhängering beim Weiterziehen der Verbauplatte in Längsrichtung des Grabens weder einer zusätzlichen Belastung ausgesetzt ist noch das Vorziehen der Platte behindert, so daß er beim Betrieb der Verbauplatte wie ein Teil der übrigen Schneide wirkt. There is an associated advantage of the solution according to the invention in that the hanging ring built into the cutting edge, the forces acting when driving into the ground due to the Intrinsic stability at least as good as the other parts the cutting edge can withstand and that the hanging ring at Pulling the shoring plate in the longitudinal direction of the trench neither Preference is still exposed to an additional burden the plate hindered, so that he during operation of the shoring plate like part of the rest of the cutting edge.

einer umlaufenden, mit den Deckblechen 2 und 3 verschweißten
Hohlprofil-Kante, die insgesamt als Rechteckrahmen-Konstruktion
5 bezeichnet wird und aus je einem ununterbrochen von Rahmenecke
6 zu Rahmenecke reichenden Hohlprofil 7, 8 oder 9 besteht.
An den Rahmenecken 6 sind die aufeinanderstoßenden Enden
der Hohlprofile 7 bis 9 so miteinander verschweißt, daß
die Rechteck-Rahmenkonstruktion 5 wie einstückig wirkt. Die
Hohlprofile 7 bis 9 können längsgeschweißt bzw. nahtlos gewalzt
oder gezogen sein. Es handelt sich also bevorzugt nicht
nur um U- oder C-Profile, sondern um rohrförmig geschlossene
Hohlprofile.The one shown in FIGS. 1 and 2, denoted in its entirety by 1

der Plattenunterkante 13 aufweisenden Spitz-Hohlprofil 9, dessen
Längsenden 9a speziell angrenzend an die Unterkante 13
zweckzäßig besonders vorteilhaft, insbesondere massiv, ausgebildet
werden. Während der Druckholm 7 und der Vertikalholm 8
einen Rechteckquerschnitt aufweisen sollen, besitzt das Spitz-Hohlprofil
der Unterkante 13 etwa einen Querschnitt in Form
eines rechtwinkligen Dreiecks, dessen eine Kathete 14 senkrecht

Hypotenuse 16 definierten Flächen des Dreieck-Querschnitts des
Spitz-Hohlprofils 9 eingepaßt werden.According to the invention, is adjacent to the
Zwischen dem geraden Umfangsbereich 21 und dem Loch 19 besitzt
der Aufhängering 18 einen sich im wesentlichen parallel zur
Plattenunterkante 13 erstreckenden Steg 24. Dieser wird bevorzugt
so ausgebildet, daß er zugleich stark bzw. voluminös genug
ist, um ebenso stabil gegen Verbiegung oder Bruch zu sein
wie der übrige Teil der Plattenunterkante 13, und schlank genug
ist, um das unmittelbare Einhängen und übergreifende Sichern
eines Kranhakens oder dergleichen Zugmittel zu gewährleisten.
Beim übergreifenden Sichern ist an eine Hakensicherung
gedacht, die beim Einhängen des Hakens gewissermaßen als
Fortsetzung der Hakenspitze um den Steg gelegt wird. Has between the straight
Wenn die Verbauplatte 1 etwa horizontal bei der Montage dirigiert
werden soll, kann der Kran, z.B. mit Seil oder Haken,
unmittelbar im Loch 19 des Aufhängerings 18 Halt finden. Der
Haken kann mit seiner Sicherung um den unteren, an die Plattenunterkante
13 angrenzenden Steg 24 herumgreifen, da ja das
Loch 19 entsprechend nahe an der Schneide 12 liegen soll. Wenn
die Platte mit Hilfe der beiden Aufhängeringe 18 nach Fig. 1
horizontal angehoben werden soll, muß das Hebemittel noch an
mindestens einer anderen Stelle an die Verbauplatte 1 angreifen.
Zu diesem Zweck werden im Ausführungsbeispiel alternativ
Aufhängeaugen 25 mit eingebauten Anschlagmitteln 26 (für Kranzugmittel
oder dergleichen) etwa im oberen Drittel der Fläche
der Verbauplatte, aber mit Abstand von den angrenzenden Hohlprofilen
7 und 8, vorgesehen. Statt dessen können auch an einen
oberen Teil des Rahmens 5, insbesondere am Hohlprofil 7,
Ziehringe 27 mit Hilfe von Ösen 28 angeschweißt werden. Das
