Description

Die Erfindung bezieht sich auf eine Schutzplankeneinrichtung für Verkehrsflächen, insbesondere zur Sicherung von Baustellen, welche aus auf den Boden aufsetzbaren, als Hohlkörper ausgebildeten Fertigteilen besteht, welche durch Zusammenstecken zug- und biegefrei miteinander zusammensetzbar sind.The invention relates to a guardrail device for traffic areas, in particular for securing construction sites, which consists of prefabricated parts which can be placed on the floor and are designed as hollow bodies and which can be assembled together by pulling and bending-free.

Bei einer bekannten Schutzplankeneinrichtung dieser Art werden die einzelnen V-förmig gebogenen Fertigteile derart zusammengesteckt, daß die jeweiligen Ränder aneinanderstoßen. Die Fertigteile sind je an einem Ende im oberen Bereich mit zwei übereinander angeordneten rohrförmigen Vorsprüngen versehen, welche in das Nachbarfertigteil hineingesteckt werden; die Fertigteile werden dann durch vertikal verlaufende Bolzen miteinander fest verbunden. Ganz abgesehen davon, daß derartige Verbindungen in der unteren Hälfte der Fertigteile vollständig fehlen, ist auch nicht gewährleistet, daß sich die Schutzplankeneinrichtung relativ leicht "überfahren" läßt. Schließlich wird durch den geringen Abstand der beiden rohrförmigen Vorsprünge eine gewisse Verdrehung der Fertigteile bei einem Fahrzeugaufprall gegeneinander nicht verhindert.In a known guardrail device of this type, the individual V-shaped finished parts are put together in such a way that the respective edges abut one another. The finished parts are each provided at one end in the upper area with two tubular projections arranged one above the other, which are inserted into the neighboring finished part; the finished parts are then firmly connected to each other by vertical bolts. Quite apart from the fact that such connections are completely missing in the lower half of the finished parts, there is also no guarantee that the guardrail device can be "run over" relatively easily. Finally, the small distance between the two tubular projections does not prevent a certain rotation of the finished parts in the event of a vehicle collision with one another.

Der Erfindung liegt die Aufgabe zugrunde, ein relativ leichtgewichtiges Fertigteilsystem zu schaffen, dessen Einzelteile sich durch eine besondere Steifigkeit auszeichnen und daß nach dem Zusammenstecken ein Verdrehen der einzelnen Fertigteile in Bezug auf die Nachbarfertigteile unmöglich ist.The invention has for its object to provide a relatively lightweight precast system, the individual parts are characterized by a particular stiffness and that after plugging together a twisting of the individual finished parts in relation to the neighboring finished parts is impossible.

Die Aufgabe wird, dadurch gelöst, daß erfindungsgemäß im Inneren der Einrichtung mindestens zwei annähernd horizontal beabstandete Platten vorgesehen sind, welche mit den Innenseiten der Seitenflächen der Einrichtung fest verbunden sind und sich beim Zusammenstecken überlappen.The object is achieved in that, according to the invention, at least two approximately horizontally spaced plates are provided in the interior of the device, which are firmly connected to the inside of the side surfaces of the device and overlap when plugged together.

Durch diese mindestens in zwei voneinander beabstandeten Ebenen vorgenommene Aussteifung der einzelnen Fertigteile ist nicht nur auch bei besonders dünnwandiger Ausbildung der Seitenbwände ein hohes Maß an Steifigkeit gegeben, sondern es wird auch verhindert, daß sich ein Fertigteil in Bezug auf die Nachbarfertteile (beim etwaigen Fahrzeugaufprall) z.B. nach oben verschiebt oder verdreht.This stiffening of the individual finished parts, which is carried out at least in two spaced-apart planes, not only provides a high degree of rigidity even in the case of a particularly thin-walled design of the side walls, but also prevents a finished part from being in relation to the neighboring finished parts (in the event of a vehicle impact). e.g. moved up or twisted.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Platten entweder im Abstand von ihren freien Enden mindestens an einer Seite abgekröpft oder weisen in den Fertigteilen eine zur Horizontalen geringfügige Neigung auf, wobei die Stirn- und/oder Seitenwände der Fertigteile sich zumindestens teileweise überlappen.According to a preferred embodiment of the invention, the plates are either bent at a distance from their free ends on at least one side or have a slight inclination to the horizontal in the finished parts, the end and / or side walls of the finished parts at least partially overlapping.

In beiden Fällen soll ermöglicht werden, daß die Steckverbindung von Fertigteil zu Fertigteil eine Relativbewegung letzterer in vertikaler Richtung verhindert.In both cases, it should be possible for the plug connection from the finished part to the finished part to prevent a relative movement of the latter in the vertical direction.

Die Stirnwände der Fertigteile und der Platten können im Randbereich übereinanderliegende Bohrungen zur lösbaren Aufnahme mindestens einer Verbundstange aufweisen. Hier kann beispielsweise eine von Hand einsetzbare Verbundstange mit einer Grifföse vorgesehen werden.The end walls of the finished parts and the plates can have bores lying one above the other in the edge area for detachably receiving at least one composite rod. Here, for example, a composite rod that can be inserted by hand can be provided with a handle eyelet.

Da erfindungsgemäß eine besonders leichte Bauweise für die einzelnen Fertigteile vorgesehen ist, können letztere aus 0,3 cm starkem Stahlblech bestehen. Die Fertigteile sind zweckmäßigerweise jeweils 1 m lang, ca. 70 cm hoch und ca. 50 kg schwer.Since, according to the invention, a particularly light construction is provided for the individual finished parts, the latter can consist of 0.3 cm thick steel sheet. The finished parts are expediently 1 m long, approx. 70 cm high and approx. 50 kg heavy.

Um unter Umständen eine weitere Gewichtserleichterung zu schaffen, können in größeren Abständen in den Platten Bohrungen oder Löcher vorgesehen werden.In order to make further weight reduction possible, holes or holes can be provided in the plates at greater intervals.

Während weiter oben von einer Gewichtserleichterung ausgegangen wird, kann in bestimmten Fällen auch die Notwendigkeit bestehen, das Gewicht der Schutzplankeneinrichtung zu erhöhen, insbesondere dann, wenn letztere eine bessere Standfestigkeit erhalten soll.While weight relief is assumed above, in certain cases there may also be a need to increase the weight of the guardrail device, in particular if the latter is to have better stability.

Für die Lösung der Aufgabe ist erfindungsgemäß vorgesehen, daß der Raum zwischen den beiden Platten mindestens im Bereich ihres einen Endes durch eine annähernd vertikale Sperre, einen Pfropfen o.dgl. abgeschlossen und der Raum mindestens teilweise gefüllt ist. Je nach dem Ausmaß der Füllung und dem gewählten Füllstoff läßt sich in einem bestimmten Rahmen das Gewicht des Fertigteils verändern. Abgesehen davon ist auch eine Leerung des Fertigteils nach Gebrauch für Transportzwecke möglich. Die Füllung wird normalerweise dadurch vorgenommen, daß das Fertigteil aufrechtgestellt und dann entsprechend der Raum nach Wunsch gefüllt wird.To achieve the object, the invention provides that the space between the two plates at least in the area of one end thereof by an approximately vertical lock, a plug or the like. completed and the room is at least partially filled. Depending on the extent of the filling and the chosen filler, the weight of the finished part can be changed within a certain range. Apart from this, the finished part can also be emptied after use for transport purposes. The filling is normally carried out by standing the finished part upright and then filling the space as required.

Die Sperre o.dgl. kann außerhalb des Bereichs der die Fertigteile zusammenhaltenden Verbindungsstange(n) vorgesehen sein. Je nachdem, wie die Fertigteile an ihren Rändern ausgebildet sind und je nachdem, wie die Verbindung der Fertigteile an Ort und Stelle erfolgt, ist die Ausbildung der Platten vorzunehmen. So können selbstverständlich auch neben der oben beschriebenen vorgeschlagenen Art des Zusammensteckens auch andere Zusammensteckmöglichkeiten vorgesehen werden. Einerseits können die Platten an einem Ende jedes Fertigteils vorkragen, so daß die jeweiligen freien Kanten benachbarter Fertigteile aneinanderstoßen; andererseits ist es natürlich auch möglich, daß z.B. zwei Verbindungsstangen zur biegefreien Verbindung der Fertigteile vorgesehen werden.The lock or the like. can be provided outside the area of the connecting rod (s) holding the finished parts together. Depending on how the prefabricated parts are designed at their edges and depending on how the prefabricated parts are connected on site, the plates must be formed. In addition to the proposed type of plugging described above, other plugging options can of course also be provided. On the one hand, the plates can protrude at one end of each finished part, so that the respective free edges of adjacent finished parts abut one another; on the other hand it is of course also possible that e.g. two connecting rods are provided for the bending-free connection of the finished parts.

Nach einer bevorzugten Ausführungsform besteht die Füllung des Raumes aus Beton. In diesem Fall ist eine Änderung des Gewichts des Fertigteils nach erfolgter Füllung nicht mehr möglich.According to a preferred embodiment, the filling of the room consists of concrete. In this case it is no longer possible to change the weight of the finished part after filling.

Anders liegt der Fall, wenn z.B. die Füllung des Raums aus Sand besteht. In diesem Fall kann das Füllen unmittelbar vor dem Zusammensetzen der Fertigteile erfolgen und kann eine Leerung nach Beendigung des Gebrauchs erfolgen. Auch läßt sich durch eine entsprechende Mengenwahl das Gewicht des Fertigteils in einem gewissen Ausmaß vorwählen.The situation is different if e.g. the space is filled with sand. In this case, the filling can take place immediately before the assembly of the finished parts and can be emptied after the end of use. The weight of the finished part can also be preselected to a certain extent by an appropriate quantity selection.

Nach einer weiteren Ausführungsform der Erfindung besteht die Füllung des Raumes aus Metallschrott. Die als Sperre ausgebildete Querwand kann mit den horizontal beabstandeten Platten fest verbunden, z.B verschweißt sein. Es ist also möglich, bereits bei der Herstellung des Fertigteils die Sperre vorzusehen und bleibend einzubringen.According to a further embodiment of the invention, the space is filled with scrap metal. The transverse wall designed as a lock can be firmly connected to the horizontally spaced plates, for example welded. It is therefore possible to provide the lock and introduce it permanently during the manufacture of the finished part.

Nach einer anderen Ausführungsform der Erfindung besteht der Pfropfen aus Holz. In diesem Fall ist eine Sperrung oder Abschließung des Raumes jederzeit, also auch im Rahmen der Zusammenstellung der Fertigteile möglich.According to another embodiment of the invention, the plug is made of wood. In this case, the room can be locked or locked at any time, including when assembling the finished parts.

Auch ist es möglich, daß im Bereich beider Enden der Platten Sperren, Pfropfen o.dgl. vorgesehen sind; dies dürfte sich vor allen Dingen dann als erforderlich erweisen, wenn z.B. leicht fließfähiges Material, wie Sand, Verwendung findet.It is also possible that in the area of both ends of the plates, locks or the like. are provided; this should prove to be necessary above all if e.g. easily flowable material, such as sand, is used.

Ein z.B. 70 cm hoher Fertigteil 1 einer Schutzplankeneinrichtung weist eine Oberwand oder Stirnwand 2 und zwei Seitenwände 3 und 4 mit einer Höhe von 45 bis 50 cm, welche zum Boden hin divergieren und an welchen sich mit einem Winkel von etwa 40 bis 50o Auffahrflächen 5 und 6 anschließen; die Höhe der Biegungsstelle 7 bzw. 8 dieser Auffahrflächen beträgt rund 15 bis 20 cm.An example 70 cm high finished part 1 of a safety barrier device comprises a top wall or end wall 2 and two side walls 3 and 4 having a height of 45 to 50 cm, which diverge towards the bottom and which is adjoined at an angle of approximately 40 to 50 o Auffahrflächen 5 and connect 6; the height of the bend 7 or 8 of these drive-on areas is around 15 to 20 cm.

An die Auffahrflächen 5 und 6 schließen sich auf der Höhe des Bodens, also z.B. der Verkehrsfläche, Auflagerbleche 9 und 10 in Streifenform an; die Auflagebleche können zum Boden gerichtete Ausstanzungen aufweisen, die ein "Verkrallen" mit der Auflagerfläche zur Folge haben.The drive-on areas 5 and 6 close at the level of the floor, e.g. the traffic area, support plates 9 and 10 in strip form; the support plates can have punchings directed towards the floor, which result in "clawing" with the support surface.

Der Fertigteil, bestehend aus 0,3 cm starken Stahlblech ist an einer Querseite so abgekröpft, daß der Nachbarfertigteil auf diesen abgekröpften Rücksprung aufschiebbar ist und daß nach dem Aufschieben, wie aus Fig. 2 ersichtlich ist, die Seitenflächen und die Stirnwand der Fertigteile bündig miteinander abschließen; nach einer abgewandelten Ausführungsform sind Laschen an der Innenseite des Fertigteils an einem Ende vorgesehen, welche dann nach dem Zusammenstecken vom Rand des Nachbarfertigteils überlappt werden, so daß auch in diesem Fall ein bündiger Übergang entsteht.The finished part, consisting of 0.3 cm thick steel sheet, is bent on one transverse side in such a way that the neighboring finished part can be pushed onto this bent recess and that, after being pushed on, as can be seen in FIG. 2, the side surfaces and the end wall of the finished parts are flush with one another to lock; According to a modified embodiment, tabs are provided on the inside of the prefabricated part at one end, which are then overlapped after being plugged together from the edge of the neighboring prefabricated part, so that a flush transition also occurs in this case.

Da die Wandungen des Fertigteils und somit der ganzen Schutzplankeneinrichtung relativ dünn sind und auch ein Fertigteil beispielsweise nur 50 kg wiegt, ist es zweckmäßig, den Fertigteil in besonderer Weise auszusteifen.Since the walls of the prefabricated part and thus the entire guardrail device are relatively thin and a prefabricated part also weighs only 50 kg, for example, it is expedient to stiffen the prefabricated part in a special way.

Zu diesem Zweck weist jeder Fertigteil mindestens zwei horizontal verlaufende oder annähernd horizintal verlaufende durchgehende Platten 12,13 auf, die sich auch auf den entsprechenden Rücksprung 11 bzw. die entsprechende Lasche erstrecken.For this purpose, each finished part has at least two horizontal or approximately horizontal continuous plates 12, 13, which also extend to the corresponding recess 11 or the corresponding tab.

Wie aus Fig. 2 ersichtlich ist, ist der Fertigteil 1 mit dem Fertigteil 20 durch Zusammenschieben zu einer festen Einheit zusammengefügt. Der Fertigteil 1 weist abgesehen davon zwei trapezförmige, vertikal verlaufende Stützwände 14,15 auf; diese Stützwände sollten mindestens im Endbereich jedes Fertigteils vorgesehen sein.As can be seen from Fig. 2, the finished part 1 is assembled with the finished part 20 by pushing them together to form a fixed unit. Apart from this, the prefabricated part 1 has two trapezoidal, vertically running support walls 14, 15; these retaining walls should be provided at least in the end area of each prefabricated part.

Um die Fertigteile ineinander schieben zu können, sind die Platten 12,13 an einem Ende nach oben oder nach unten abgekröpft oder schräg gestellt, so daß die entsprechenden Platten der Nachbarplatten darunter oder darüber greifen können. Hierdurch sind somit die Enden von zwei Fertigteilen nach dem Zusammenstecken in vertikaler Richtung dadurch miteinander verriegelt, daß die Plattenenden des einen Fertigteils diejenigen des anderen Fertigteils untergreifen und die Randbereiche des ersteren diejenigen des zweiten übergreifen oder umgekehrt.In order to be able to push the finished parts into one another, the plates 12, 13 are bent at one end upwards or downwards or inclined so that the corresponding plates of the neighboring plates can reach below or above them. As a result, the ends of two finished parts are thus locked together in the vertical direction after being plugged together in that the plate ends of one finished part engage under those of the other finished part and the edge regions of the former overlap those of the second or vice versa.

Die Oberwand und die Platten werden miteinander durch einen lösbaren oder herausziehbaren Verbindungsstab 30 miteinander verbunden; dieser Verbindungsstab kann an seinem oberen Ende eine Öse aufweisen um ihn besser handhaben zu können. Durch die als Versteifung dienenden Platten 12 und 13 wird nicht nur ein Eindrücken der Seitenwände 3 und 4 bei einem aufprallenden Fahrzeug verhindert oder zumindestens eingeschränkt, sondern es wird auch verhindert, daß der Seitenwandteil 3 bzw. 4 mit der Stirnwand 2 bei einem Aufprall eingeknickt oder ggfs. überfahren wird. Die Steckverbindung der oben beschriebenen Art ist allein ausreichend die Schutzplankeneinrichtung zusammenzuhalten. Nur in Ausnahmefällen können zusätzlich im Randbereich der Fertigteile Schraubbolzen verwendet werden.The top wall and the plates are connected to one another by a releasable or pull-out connecting rod 30; this connecting rod can have an eyelet at its upper end in order to be able to handle it better. The plates 12 and 13 serving as stiffening not only prevent or at least restrict the side walls 3 and 4 from being pressed in in the event of an impact, but also prevent the side wall parts 3 and 4 from buckling with the end wall 2 in the event of an impact or may be run over. The plug connection of the type described above is sufficient to hold the guardrail device together. Only in exceptional cases can bolts be used in the edge area of the finished parts.

Die zu einer Schutzplankeneinrichtung zusammengesetzten Fertigteile 1 bzw. 20 sind, wie bereits oben bemerkt, relativ leicht, also z.B. je 50 kg schwer, wobei eine Länge des Fertigteils von ca. 1 m unterstellt wird; es können natürlich auch längere Fertigteile, z.B. bis 1,50 m oder mehr vorgesehen werden.The prefabricated parts 1 and 20, which are assembled to form a guardrail device, are, as already noted above, relatively light, that is to say for example 50 kg each, a length of the prefabricated part of approximately 1 m being assumed; it can of course longer finished parts, for example up to 1.50 m or more, can also be provided.

Eine Umsetzung der Schutzplankeneinrichtung, wie sie beim Baustellenbetrieb häufig vorkommt, ist daher relativ einfach und ohne große Aufwendungen, also z.B. Kräne o.dgl. möglich.Implementing the guardrail device, as is often the case on construction site operations, is therefore relatively simple and without great expenditure, e.g. Cranes or the like possible.

Bei der in den Fig. 3 und 4 dargestellten Ausführungsform, beispielsweise mit einer Höhe von 40 - 55 cm handelt es sich um eine solche, die beim Baustellenbetrieb im wesentlichen zur Markierung vorgesehen wird. Der Aufbau dieser Ausführungsform ähnelt derjenigen nach Fig. 1 und Fig. 2 weitgehend, so daß auf Beschreibung von Einzelheiten, soweit sie mit denjenigen in Fig. 1 und 2 übereinstimmem, verzichtet wird. Aufgrund der relativ geringen Höhe ist die Abweisfunktion dieser relativ leicht ausgebildeten Schutzplankeneinrichtung recht gering. Dies gilt vor allem, wenn die Schutzplankeneinrichtung aus Kunststoff hergestellt wird. Bei einer Fertigung aus Stahl ist allerdings eine erhöhte Abweisfunktion festzustellen.The embodiment shown in FIGS. 3 and 4, for example with a height of 40-55 cm, is one that is essentially provided for marking during construction site operation. The structure of this embodiment is largely similar to that of FIGS. 1 and 2, so that the description of details, insofar as they correspond to those in FIGS. 1 and 2, is dispensed with. Due to the relatively low height, the rejection function of this relatively lightly designed guardrail device is quite low. This is especially true if the guardrail device is made of plastic. When manufacturing from steel, however, an increased rejection function can be determined.

Die gesamte "Außenhaut" des Fertigteils, das beispielsweise 1,50 m lang sein kann, kann einstückig hergestellt werden.The entire "outer skin" of the finished part, which can be, for example, 1.50 m long, can be manufactured in one piece.

Im Inneren des als Hohlkörper ausgebildeten Fertigteils sind zwei parallele Platten 12 und 13 vorgesehen, die auf beliebige Weise mit der Außenhaut verbunden werden können.In the interior of the prefabricated hollow part, two parallel plates 12 and 13 are provided, which can be connected to the outer skin in any way.

Die beiden Platten 12 und 13 erstrecken sich über die gesamte Länge des Fertigteils; die beiden Platten sind jeweils mit einem rückspringenden Rand versehen, so daß die Enden der entsprechenden Platten des Nachbarfertigteils, wie aus Fig. 4 ersichtlich, auf den rückspringenden Rändern der Platten 12 und 13 aufliegen können.The two plates 12 and 13 extend over the entire length of the finished part; the two plates are each provided with a recessed edge, so that the ends of the corresponding plates of the neighboring prefabricated part, as in FIG. 4 can be seen lying on the recessed edges of the plates 12 and 13.

Auch in diesem Fall können andereKonstruktionen bzw. eine andere Ausbildung der Fertigteile Verwendung finden.In this case too, other designs or a different design of the finished parts can be used.

Nach der Erfindung ist zwischen den Platten 12 und 13 eine Querwand 15 vorgesehen; diese Querwand besitzt einen gewissen Abstand von den freien Enden 22 bzw. 23 der Platten 12 und 13, so daß die Verbindungsstange 30 nach dem Zusammensetzen der Fertigteile eingeschoben werden kann. Die Querwand 21 kann bereits bei Anfertigen der Fertigteile vorgesehen werden.According to the invention, a transverse wall 15 is provided between the plates 12 and 13; this transverse wall has a certain distance from the free ends 22 and 23 of the plates 12 and 13, so that the connecting rod 30 can be inserted after the assembly of the finished parts. The transverse wall 21 can already be provided when the finished parts are made.

Die Füllung des Raumes zwischen der Querwand und den gegenüberliegenden Enden der Platten 12 und 13 kann entweder bei der Serienfertigung, z.B. mit Beton, erfolgen; es kann aber auch eine nachträgliche Füllung des erwähnten Raumes an der Baustelle, z.B. mit Sand oder Kies vorgenommen werden. In diesem Fall ist eine Leerung des Raumes 20 vor dem etwaigen Transport zu einer anderen Baustelle ohne weiteres möglich.The filling of the space between the transverse wall and the opposite ends of the plates 12 and 13 can be done either in series production, e.g. with concrete, done; But it can also be a subsequent filling of the space mentioned at the construction site, e.g. be made with sand or gravel. In this case, the space 20 can be emptied without any problems before being transported to another construction site.

Das Fertigteil kann mit trapezförmigen Verstrebungswänden 15 bzw. 14 an den Wänden des Fertigteils versehen sein.The finished part can be provided with trapezoidal strut walls 15 or 14 on the walls of the finished part.

Die Konstruktion des Fertigteils kann variieren; in jedem Fall müssen jedoch die beiden Platten 12 und 13 vorgesehen sein. Statt der schon bei der Fertigstellung des Fertigteils eingebauten Querwand 15 kann auch dieser Teil in Wegfall kommen.The construction of the finished part can vary; in any case, however, the two plates 12 and 13 must be provided. Instead of the transverse wall 15 already installed when the finished part is finished, this part can also be omitted.

Es ist stattdessen möglich, einen Pfropfen entsprechend den Umrissen des Raumes vorzusehen, der dann z.B. auf der Baustelle zum Abschluß des Raumes 20 von einer Seite hineingeschoben wird. Danach erfolgt die Füllung, z.B. mit Sand, in aufrechter Stellung des Fertigteils und schließlich der Abschluß des Raumes auf der anderen Seite mit einem entsprechenden Pfropfen. Diese Pfropfen können aus Holz oder irgendeinem anderen beliebigen Material bestehen.Instead, it is possible to provide a plug according to the outline of the room, which can then be used on the construction site, for example at the end of the room 20 is pushed in from one side. This is followed by filling, for example with sand, in the upright position of the finished part and finally closing off the room on the other side with a corresponding plug. These plugs can be made of wood or any other material.
