Description

Die Erfindung betrifft ein vorgefertigtes Bauelement zur Errichtung mobiler Schutzbarrieren an Fahrbahnen, insbesondere Schutzbarrieren zur Abgrenzung von Fahrbahnen gegeneinander, mit einem nach unten offenen Stahlblechprofil, das an seinen Enden Einrichtungen zur Verbindung solcher Stahlblechprofile zu einem entlang der Fahrbahn vom Boden aufragenden Schwellenstrang aufweist.The invention relates to a prefabricated structural element for erecting mobile protective barriers on roadways, in particular protective barriers for the delimitation of roadways against each other, with a downwardly open sheet steel profile having at its ends means for connecting such sheet steel profiles to a rising along the roadway from the ground threshold strand.

Bekanntermaßen kommen mobile Schutzbarrieren, d.h. demontierbare Schutzbarrieren ohne Bodenverankerung, an vorübergehend eingerichteten Fahrbahnen, vor allem an Straßen- und Autobahnbaustellen, zum Einsatz. Insbesondere werden die aus Stahl- oder Betonbauelementen gebildeten Schutzbarrieren zwischen schmalen Fahrspuren angeordnet, die oftmals in entgegengesetzten Richtungen befahren werden und zu deren Einrichtung an Autobahnbaustellen zumeist nur ein Teil der Breite einer Richtungsfahrbahn zur Verfügung steht.It is known that mobile protective barriers, i. demountable protective barriers without ground anchoring, on temporary lanes, especially on road and highway construction sites, for use. In particular, the protective barriers formed of steel or concrete elements between narrow lanes are arranged, which are often used in opposite directions and their device at highway construction sites usually only part of the width of a directional lane is available.

Solche Schutzbarrieren sollen seitlich von der Fahrbahn abkommende Fahrzeuge wirksam zurückhalten, wobei es vor allem darauf ankommt, dass sich die Schutzbarriere bei seitlichem Anprall eines Fahrzeugs nicht zu weit in den Bereich einer unmittelbar benachbarten Fahrbahn hinein ausbaucht.Such protective barriers are intended to effectively restrain vehicles coming off the roadway, whereby it is important that the protective barrier does not bulge too far into the area of an immediately adjacent roadway in the event of a side impact of a vehicle.

Um für die vorstehend beschriebenen Einsatzzwecke zugelassen zu werden, müssen die Schutzbarrieren eine Reihe unter normierten Bedingungen durchzuführender Anpralltests bestehen, wobei je nach Einsatzort der Schutzbarrieren unterschiedliche Testanforderungen zu erfüllen sind.In order to be approved for the purposes described above, the protective barriers must pass a series of impact tests under standardized conditions, with different test requirements depending on the location of the protective barriers.

Stahlblechprofile umfassende Bauelemente der eingangs genannten Art sind aus der DE 38 27 030 C2 , der EP 1 418 274 B1 und der DE 10 2006 047 808 A1 bekannt. Zur Herstellung eines auf dem Boden aufliegenden Schwellenstrangs werden diese Stahlblechprofile unter Bildung eines Stoßes aneinandergesetzt. Der gegenseitigen Fixierung der aneinander stoßenden Profile dienen Laschen, die innenseitig mit den Profilblechen der aneinander stoßender Profile verschraubt sind, oder mit den Profilen verbundene Elemente zur gegenseitigen Verhakung.Sheet steel profiles comprehensive components of the type mentioned are from the DE 38 27 030 C2 , of the EP 1 418 274 B1 and the DE 10 2006 047 808 A1 known. For producing a threshold strand resting on the ground, these steel sheet profiles are put together to form a joint. The mutual fixation of the abutting profiles serve tabs which are bolted on the inside with the profile sheets of the abutting profiles, or connected to the profiles elements for mutual entanglement.

Darüber hinaus durch Benutzung bekannte Bauelemente der eingangs genannten Art weisen ein Stahlblechprofil auf, das sich mit großen Biegeradien nach unten zu einem verhältnismäßig breiten Fußteil aufweitet. Auch diese Stahlblechprofile werden endseitig aneinanderstoßend miteinander verbunden, wobei die Stahlblechprofile über innenseitig angebrachte Verbindungslaschen miteinander verschraubt werden.In addition, by using known components of the type mentioned have a sheet steel profile, which widens with large bending radii down to a relatively wide foot. These steel sheet profiles are connected to each other at the end abutting each other, wherein the steel sheet profiles are screwed together on the inside attached connecting straps.

Die DE 197 18 227 C1 offenbart ein Bauelement zur Errichtung mobiler Schutzbarrieren an Fahrbahnen mit einem nach unten offenen Stahlblechprofil, das an seinen Enden Einrichtungen zur Verbindung solcher Stahlblechprofile zu einem entlang der Fahrbahn vom Boden aufragenden Schwellenstrang aufweist. Die Verbindungseinrichtungen sind zur Verbindung der Stahlblechprofile unter Überlappung ihrer Enden vorgesehen.The DE 197 18 227 C1 discloses a device for erecting mobile protective barriers on roadways with a downwardly open sheet steel profile having at its ends means for connecting such steel sheet profiles to a along the road from the ground towering threshold strand. The connecting means are provided for connecting the steel sheet profiles with overlapping their ends.

Auch die DE 38 27 030 C2 und die DE 198 33 560 A1 offenbaren Bauelemente zur Errichtung mobiler Schutzbarrieren an Fahrbahnen.Also the DE 38 27 030 C2 and the DE 198 33 560 A1 disclose components for the construction of mobile protective barriers on roadways.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein neues Bauelement zur Errichtung mobiler Schutzbarrieren an Fahrbahnen der eingangs erwähnten Art zu schaffen, das trotz verringerter Breite und ggf. verringertem Materialeinsatz die für mobile Schutzbarrieren geltenden Normanforderungen erfüllt und sich zudem mit verringertem Aufwand herstellen und montieren lässt.The present invention has for its object to provide a new device for the construction of mobile protective barriers on roadways of the type mentioned, despite the reduced width and possibly reduced use of materials meets the requirements for mobile protective barriers standard requirements and also can be produced and assembled with reduced effort ,

Die Lösung dieser Aufgabe besteht in einem Bauelement gemäß den Merkmalen in Anspruch 1.The solution to this problem consists in a device according to the features in claim 1.

Vorteilhaft lässt sich durch die erfindungsgemäße Überlappung der Profilenden eine wesentliche Erhöhung der Festigkeit des Schwellenstrangs erreichen, insbesondere eine höhere, die Ausbauchung des Schwellenstrangs bei seitlichem Anprall begrenzende Steifigkeit. Somit lassen sich die geltenden Normanforderungen trotz verringerter Breite des Stahlblechprofils und sogar bei verringertem Materialeinsatz erfüllen, wobei die verringerte Breite der Stahlblechprofile der Breite der zu begrenzenden Fahrbahn zugute kommt.The overlapping of the profiled ends according to the invention advantageously makes it possible to achieve a substantial increase in the strength of the sleeper strand, in particular a higher rigidity which limits the bulging of the sleeper strand in the event of a lateral impact. Thus, the existing standard requirements can be met despite reduced width of the sheet steel profile and even with reduced material use, the reduced width of the sheet steel profiles of the width of the track to be limited benefits.

Gemäß der Erfindung sind die Stahlblechprofile an den zu verbindenden Enden derart aneinander angepasst, dass die einander überlappenden Profilenden über deren gesamte Profilquerschnitte aneinander anliegen.According to the invention, the steel sheet profiles are adapted to each other at the ends to be joined such that the overlapping profile ends abut each other over the entire profile cross-sections.

Diese Anpassung wird dadurch erreicht, dass sich Abmessungen des Profilquerschnitts des Stahlblechprofils gleichmäßig über die gesamte Profillänge ändern. Solche Änderungen lassen sich mit geringem Fertigungsaufwand dadurch erreichen, dass das Blech bei der Herstellung des Profils entlang zueinander geneigter Linien abgekantet wird. Die Herstellung eines angepassten Endabschnitts durch Kröpfung wäre deutlich aufwendiger.This adaptation is achieved in that the dimensions of the profile cross section of the sheet steel profile change uniformly over the entire profile length. Such changes can be achieved with low manufacturing costs, that the sheet is folded in the production of the profile along mutually inclined lines. The production of an adapted end section by cranking would be significantly more complicated.

Das Stahlblechprofil des Bauelements nach der Erfindung weist vorzugsweise ebene, durch eine Abkantung voneinander getrennte Profilwandabschnitte auf, insbesondere ausschließlich solche Profilwandabschnitte. Ein solches ausschließlich Abkantungen mit geringem Biegeradius aufweisendes Stahlblechprofil kann bei geringer Breite mit hoher Steifigkeit ohne Neigung zur Rückfederung bei der Ankantung hergestellt werden, was neben der Überlappung zur Erhöhung der Festigkeit des aus den Stahlblechprofilen gebildeten Schwellenstrangs beiträgt.The sheet steel profile of the component according to the invention preferably has planar profile wall sections which are separated from one another by a fold, in particular exclusively such profile wall sections. Such a steel sheet profile having only small bends and having only small bends can be produced with high rigidity and without inclination to spring back when bent, which contributes, in addition to the overlap, to increasing the strength of the sleeper strand formed from the steel sheet profiles.

Das Stahlblechprofil ist als Hutprofil ausgebildet mit nach oben dachartig zusammenlaufenden Seitenwandabschnitten, einem horizontalen Deckenwandabschnitt sowie horizontalen oder leicht nach unten z.B. um 1° bis 3° geneigten Fußabschnitten.The sheet steel profile is designed as a hat profile with roof-like converging side wall sections, a horizontal ceiling wall section and horizontal or slightly downwards, for example, by 1 ° to 3 ° inclined foot sections.

Zur Anpassung der miteinander zu verbindenden Profilenden verringert sich die Breite des Deckenwandabschnitts und ggf. die Breite der Fußabschnitte über die gesamte Länge des Stahlblechprofils gleichmäßig.To adapt the profile ends to be joined together, the width of the ceiling wall section and possibly the width of the foot sections over the entire length of the sheet steel profile is reduced uniformly.

Die Fußabschnitte des Hutprofils können durch lösbare, zur Auflage auf dem Boden vorgesehene Fußplatten miteinander verbunden sein. Die lösbare Verbindung des Stahlblechprofils mit den Fußplatten ermöglicht es, die insbesondere in der obengenannten Weise als Hutprofil ausgebildeten Stahlblechprofile zu stapeln, sodass sie sich effizient zur Baustelle transportieren lassen.The foot portions of the hat profile may be interconnected by releasable, provided for resting on the floor foot plates. The detachable connection of the sheet steel profile with the foot plates makes it possible to stack the steel sheet profiles designed in particular in the above-mentioned manner as a hat profile, so that they can be efficiently transported to the construction site.

In weiterer vorteilhafter Ausgestaltung der Erfindung weisen die Fußplatten auf ihrer dem Boden zugewandten Seite einen weichen Belag auf, der für einen hohen, die Rutschfestigkeit des Schwellenstrangs auf dem Boden verbessernden Haftreibungskoeffizienten sorgt.In a further advantageous embodiment of the invention, the foot plates on their side facing the ground on a soft coating, which ensures a high, the slip resistance of the threshold strand on the ground improving static coefficient of friction.

Eine lösbar befestigte Fußplatte kann insbesondere auch im Überlappungsbereich der miteinander verbundenen Stahlblechprofile vorgesehen sein, wobei vorteilhaft die Fußplatte mit beiden einander überlappenden Fußabschnitten verbunden und so über die Verbindung mit der Fußplatte die Verbindung zwischen den Stahlblechprofilen weiter stabilisiert ist.A releasably fastened foot plate may be provided in particular in the overlapping region of the interconnected sheet steel profiles, wherein advantageously the base plate connected to two overlapping foot sections and so on the connection with the base plate, the connection between the steel sheet profiles is further stabilized.

Zweckmäßig weist das Stahlblechprofil an seinen Enden Elemente für eine Formschlussverbindung auf und ist insbesondere an einem Ende mit wenigstens einem Zapfen verbunden, der von dem Deckenwandabschnitt nach unten vorsteht, wobei an dem anderen Ende in dem Deckenwandabschnitt eine Öffnung für den Eingriff eines solchen Zapfens gebildet ist. Vorteilhaft kann so zur Verbindung zweier Bauelemente der zur Überlappung vorgesehene Teil des einen Bauelements von oben auf den zur Überlappung vorgesehenen Teil des anderen Bauelements unter Einführung des Zapfens in die Öffnung abgesenkt werden.Suitably, the steel sheet has at its ends elements for a positive connection and is in particular connected at one end to at least one pin which projects downwardly from the top wall portion, wherein at the other end in the top wall portion an opening for the engagement of such a pin is formed , Advantageously, in order to connect two components, the part of the one component provided for overlapping can be lowered from above onto the part of the other component provided for overlapping with the pin being introduced into the opening.

An die Öffnung kann sich nach unten eine Führung für den Zapfen, insbesondere eine rohrförmige Führung, anschließen.To the opening can down a guide for the pin, in particular a tubular guide, connect.

Insbesondere bei Verwendung von zwei zueinander im Abstand angeordneten Zapfen und Öffnungen sind die miteinander zu verbindenden Stahlblechprofile so genau zueinander ausgerichtet, dass für zusätzliche Schraubverbindungen vorgesehene Bohrungen genau zur Deckung kommen, was die Montage der Teile wesentlich erleichtert.In particular, when using two mutually spaced pins and openings to be joined together steel sheet profiles are so precisely aligned with each other, that provided for additional screw holes provided to cover exactly what the assembly of the parts much easier.

In weiterer vorteilhafter Ausgestaltung der Erfindung kann das Stahlblechprofil Einrichtungen für die Anbringung eines den Schwellenstrang erhöhenden Aufbaus aufweisen, insbesondere einen im Abstand über dem Schwellenstrang durch vertikale Stützelemente gehaltenen, aus weiteren Stahlblechprofilen gebildeten Holm. Entsprechend kann das den Schwellenstrang bildende Stahlblechprofil Grundbaustein eines umfassenderen modularen Systems zur Errichtung unterschiedlicher Schutzbarrieren sein, die verschiedene Normanforderungen erfüllen.In a further advantageous embodiment of the invention, the sheet steel profile may have facilities for the attachment of a threshold strand increasing structure, in particular a spaced above the threshold strand by vertical support elements held, formed from other steel sheet profiles spar. Accordingly, the steel sheet profile forming the threshold strand can be the basic component of a more comprehensive modular system for establishing different protective barriers that meet various standard requirements.

Die genannten Einrichtungen können Öffnungen für die Herstellung von Bajonettverbindungen zwischen dem Schwellenstrang und dem Aufbau, insbesondere Bajonettverbindungen mit den vertikalen Stützelementen umfassen. Gegebenenfalls kann durch Drehung der vertikalen Stützen gleichzeitig eine Bajonettverbindung der vertikalen Stützen mit dem den Schwellenstrang bildenden Stahlblechprofil und dem Stahlblechprofil für den Holm herstellbar sein. Vorzugsweise ist der Holm jedoch mit den Stützelementen verschraubt.Said means may comprise openings for the production of bayonet joints between the sleeper strand and the structure, in particular bayonet joints with the vertical support elements. Optionally, by rotating the vertical supports at the same time a bayonet connection of the vertical supports with the threshold strand forming sheet steel profile and the steel sheet profile for the spar can be produced. Preferably, however, the spar is bolted to the support elements.

Auch die den Holm bildenden Stahlblechprofile können sich an den Verbindungsstellen überlappen, wobei, wie bei dem Grundbaustein, eine Anpassung der Überlappungsenden, z.B. durch zueinander geneigte Abkantungen des vorzugsweise als C-Profil ausgebildeten Stahlblechprofils, herstellbar ist.Also, the steel sheet profiles forming the spar may overlap at the joints, wherein, as in the basic brick, an adjustment of the overlap ends, e.g. can be produced by mutually inclined bends of the preferably formed as a C-profile steel sheet profile.

Das als Hutprofil symmetrisch zu einer Mittelebene ausgebildete Stahlblechprofil 1 weist einen zur horizontalen Anordnung vorgesehenen Deckenwandabschnitt 2 auf, von dem in einem Winkel > 90 ° nach unten dachartig auseinanderlaufende Seitenwandabschnitte 3 und 4 abgekantet sind. An die Seitenwandabschnitte 3 und 4 schließt sich je ein Fußabschnitt 5 bzw. 6 an. Die zu dem Deckenwandabschnitt 2 etwa parallel verlaufenden Fußabschnitte 5 und 6 weisen jeweils eine sich zum übrigen Fußabschnitt im stumpfen Winkel erstreckende Randabkantung 7 bzw. 8 auf.The trained as a hat profile symmetrically to a median plane sheet steel profile 1 has a horizontal arrangement provided for ceiling wall portion 2, from which at an angle> 90 ° down roof-like diverging side wall sections 3 and 4 are folded. At the side wall portions 3 and 4, each a foot section 5 and 6 connects. The foot portions 5 and 6, which run approximately parallel to the top wall section 2, each have a marginal edging 7 or 8 extending at an obtuse angle to the rest of the foot section.

In dem Deckenwandabschnitt 2 des Stahlblechprofils 1 sind an dem in Fig. 1 gezeigten Profilende in Profillängsrichtung im Abstand zueinander Öffnungen 9 und 10 vorgesehen.In the top wall portion 2 of the sheet steel profile 1 are at the in Fig. 1 Profiled end shown in the profile longitudinal direction at a distance from each other openings 9 and 10 are provided.

An dem diesem Ende entgegengesetzten, in Fig. 2 gezeigten Ende befinden sich an den betreffenden Stellen rohrförmige Zapfen 11 und 12, die von dem Deckenwandabschnitt 2 nach unten vorstehen. Der Außendurchmesser der Zapfen 11 und 12 entspricht dem Innendurchmesser der Öffnungen 9 und 10. Abweichend von dem gezeigten Ausführungsbeispiel könnten sich an die Öffnungen 9 und 10 nach unten vorstehende rohrförmige Führungen mit gleichem Innendurchmesser anschließen.At the opposite end, in Fig. 2 shown end are located at the relevant points tubular pin 11 and 12 projecting from the top wall portion 2 down. The outer diameter of the pins 11 and 12 corresponds to the inner diameter of the openings 9 and 10. Notwithstanding the embodiment shown could be to the openings 9 and 10th connect downwardly protruding tubular guides with the same inner diameter.

An dem in Fig. 1 gezeigten Ende ist jeweils in den Seitenwänden 3 und 4 eine Montageöffnung 13 bzw. 14 vorgesehen. Jedes der in Fig. 1 und 2 gezeigten Enden weist ferner je vier Bohrungen 15 in den Seitenwandabschnitten 3 und 4 auf, deren Funktion, wie die der Montageöffnungen 13,14, weiter unten erläutert ist. Über die Länge des Stahlblechprofils 1 verteilt sind ferner Paare sich verengender Langlöcher 16 für eine Bajonettverbindung gebildet. In der Längsmitte des Stahlblechprofils 1 gebildete Randausnehmungen 25 verhindern einen Wasserstau.At the in Fig. 1 shown end, a mounting opening 13 and 14 is respectively provided in the side walls 3 and 4. Each of the in Fig. 1 and 2 The ends shown also each have four holes 15 in the side wall sections 3 and 4, whose function, as that of the mounting holes 13,14, explained below. Distributed over the length of the sheet steel profile 1 are also pairs of narrowing slots 16 formed for a bayonet connection. Edge recesses 25 formed in the longitudinal center of the sheet steel profile 1 prevent a water accumulation.

Wie Fig. 3 und 4 erkennen lassen, werden zur Bildung eines Schwellenstrangs die Stahlblechprofile 1 jeweils mit mehreren Fußplatten 17 verschraubt, über welche das Bauelement auf dem Boden aufsitzt und welche an ihrer dem Boden zugewandten Unterseite einen weichen Belag 19 zur Erhöhung der Rutschfestigkeit aufweisen. Es versteht sich, dass diese Fußplatten auch maßgeblich zur Stabilität des Schwellenstrangs beitragen.As 3 and 4 can recognize the steel sheet profiles 1 are each bolted to a plurality of base plates 17, via which the device is seated on the ground and which have on their underside facing the bottom a soft coating 19 to increase the slip resistance to form a threshold strand. It is understood that these foot plates also contribute significantly to the stability of the threshold strand.

Zweckmäßig erfolgt die Montage der Fußplatten 17 erst vor Ort im Zuge der Errichtung eines Schwellenstrangs. Vorteilhaft lassen sich die Stahlblechprofile dann im gestapelten Zustand zur Baustelle transportieren.Appropriately, the assembly of the foot plates 17 takes place only on site in the course of the establishment of a threshold strand. Advantageously, the steel sheet profiles can then be transported in stacked condition to the construction site.

Bei der Errichtung eines Schwellenstrangs durch Aneinanderreihung vorangehend beschriebener Bauelemente gemäß Fig. 4 wird auf das in Fig. 1 gezeigte Ende des Stahlblechprofils 1 unter Überlappung der Profilenden das in Fig. 2 gezeigte Ende eines benachbarten Bauelements von oben aufgesetzt, so dass die Zapfen 11,12 des benachbarten Bauelements in die Öffnungen 9,10 eingreifen. Die einander überlappenden Profilenden sind derart aneinander angepasst, dass die Stahlblechprofile 1 im Überlappungsbereich über ihren gesamten Querschnitt aneinander anliegen. Diese Anpassung ist dadurch gegeben, dass die jeweils in einer gemeinsamen horizontalen Ebene liegenden Abkantlinien zwischen den Wandabschnitten 2 bis 7 wie auch die freien Ränder des Stahlblechprofils 1 nicht exakt zueinander parallel ver-laufen sondern in diesen horizontalen Ebenen geringfügig zueinander geneigt sind.In the construction of a threshold strand by juxtaposition of previously described components according to Fig. 4 will be on the in Fig. 1 shown end of the sheet steel profile 1 with overlap of the profile ends in Fig. 2 shown end of an adjacent device placed from above, so that the pins 11,12 of the adjacent component engage in the openings 9,10. The overlapping profile ends are adapted to one another such that the steel sheet profiles 1 abut each other over their entire cross section in the overlapping region. This adaptation is given by the fact that each lying in a common horizontal plane bending lines between the wall sections 2 to 7 as well as the free edges of the sheet steel profile 1 not exactly parallel to each other run but slightly inclined to each other in these horizontal planes.

An den Überlappungsbereichen, deren Längsausdehnung in dem gezeigten Ausführungsbeispiel 0,5 m beträgt, bei einer Länge der Stahlblechprofile 1 von 6 m, ist eine gegenüber den übrigen Platten 17 längere Fußplatte 17' angebracht. Durch Schraubverbindung mit der Fußplatte 17' werden auch die sich überlappenden Fußabschnitte 5,6 der Stahlblechprofile 1 miteinander verbunden. Ein überstehendes Ende der Fußplatte 17' ist nur mit einem der beiden miteinander verbundenen Stahlblechprofile 1 verschraubt.At the overlapping areas, the longitudinal extent in the illustrated embodiment is 0.5 m, with a length of the steel sheet profiles 1 of 6 m, a relative to the other plates 17 longer foot plate 17 'is mounted. By screwing with the base plate 17 'and the overlapping foot sections 5.6 of the sheet steel profiles 1 are connected to each other. An overhanging end of the foot plate 17 'is bolted to only one of the two interconnected sheet steel profiles 1.

Der gemäß Fig. 4 aus den Stahlblechprofilen 1 und Fußteilen 17,17' gebildete Schwellenstrang weist bei geringer Breite und verhältnismäßig geringem Materialeinsatz eine in horizontaler Richtung hohe Quersteifigkeit auf, wozu einerseits die Überlappungen an den Verbindungsenden der Stahlblechprofile 1 und andererseits die zahlreichen Abkantungen des Stahlblechprofils mit geringen Biegeradien < 6 mm beitragen.The according to Fig. 4 formed from the steel sheet profiles 1 and foot parts 17,17 'threshold strand has low width and relatively low material usage on a high horizontal transverse stiffness, including on the one hand, the overlaps on the connecting ends of the sheet steel profiles 1 and on the other hand, the numerous folds of the sheet steel profile with low bending radii mm contribute.

Wie aus den Fig. 5 bis 7 hervorgeht, lässt sich der Schwellenstrang zu einer Schutzbarriere von größerer Höhe erweitern, die höheren Schutznormanforderungen als der Schwellenstrang genügt und z.B. an besonders gefährdeten Abschnitten von Fahrbahnen zum Einsatz kommt.Like from the Fig. 5 to 7 As a result, the tie-line can be extended to a protective barrier of greater height, which meets higher protection standard requirements than the tie-line and is used, for example, on particularly hazardous sections of carriageways.

In dem in Fig. 5 gezeigten modularen System bilden die Bauelemente aus Stahlblechprofilen 1 und Fußteilen 17,17' einen Grundbaustein, der mit vertikalen Stützelementen 20 und einem weiteren Stahlblechprofil 21 von der Länge des Stahlblechprofils 1 verbindbar ist. In dem gezeigten Beispiel handelt es sich bei dem weiteren Stahlblechprofil 21 um ein C-Profil.In the in Fig. 5 shown modular system, the components of sheet steel profiles 1 and foot parts 17,17 'form a basic building block, which is connectable with vertical support members 20 and a further sheet steel profile 21 of the length of the sheet steel profile 1. In the example shown, the further steel sheet profile 21 is a C-profile.

Wie Fig. 6 zeigt, sind am unteren Ende der Stützen 20 zwei hinterschnittene Zapfen 22 für den Eingriff in die oben erwähnten Langlöcher 16 vorgesehen. Bei Drehung der Stützen hintergreifen die Zapfen Verengungen der Langlöcher und es ist eine Bajonettverbindung zwischen dem Stützelement 20 und dem Stahlblechprofil 1 hergestellt. Zur Schraubverbindung mit dem Stahlblechprofil 21 dienen Gewindebohrungen 23 in einer Montageplatte am oberen Ende der Stützelemente 20. Denkbar wäre auch eine zusätzliche Bajonettverbindung zwischen den Stützelementen 20 und dem Stahlblechprofil 21, wobei als Stahlblechprofil 21 ein geschlossenes Kastenprofil verwendbar wäre.As Fig. 6 shows, two undercut pins 22 are provided for engaging in the above-mentioned slots 16 at the lower end of the supports 20. Upon rotation of the supports, the pins engage behind constrictions of the elongated holes and a bayonet connection between the support element 20 and the steel sheet profile 1 is produced. Threaded holes 23 in a mounting plate at the upper end of the support elements 20 are used for screw connection with the sheet steel profile 21. It would also be conceivable to have an additional bayonet connection between them Support elements 20 and the steel sheet 21, wherein a steel box profile 21, a closed box section would be used.

Wie aus Fig. 7 hervorgeht, lassen sich aus den in Fig. 5 und 6 gezeigten Bauteilen Schutzbarrieren mit einem über der Schutzschwelle durch die Stützelemente 20 im Abstand gehaltenen, aus Stahlblechprofilen 21 gebildeten Holm errichten. Wie die Stahlblechprofile 1 überlappen sich auch die Stahlblechprofile 21 an den Verbindungsstellen, wobei die Stahlblechprofile 21 in den Überlappungsbereichen Bohrungen 24 für Schraubverbindungen aufweisen.How out Fig. 7 can be deduced from the in FIGS. 5 and 6 shown building barriers with a above the protection threshold by the support members 20 at a distance, formed from sheet steel profiles 21 spar. Like the steel sheet profiles 1, the steel sheet profiles 21 also overlap at the connection points, the steel sheet profiles 21 having holes 24 for screw connections in the overlapping areas.

Im Falle der Errichtung einer durch die Stützelemente 20 und Stahlblechprofile 21 erweiterten Schutzbarriere werden zur Verbindung der Stahlblechprofile 1 zusätzlich die oben erwähnten Bohrungen 15 genutzt, wobei für die Herstellung von Schraubverbindungen die ferner genannten Montageöffnungen 13 und 14 hilfreich sind.In the case of the construction of a protective barrier extended by the supporting elements 20 and steel sheet profiles 21, the above-mentioned holes 15 are additionally used to connect the steel sheet profiles 1, with the assembly openings 13 and 14, which are also mentioned, being helpful for the production of screw connections.

In dem gezeigten Ausführungsbeispiel weisen die Stahlblechprofile 21 einen durchgehend gleichbleibenden Querschnitt auf. Im Überlappungsbereich kommt es daher zu leichten Verbiegungen des Blechs. Auch die Stahlblechprofile 21 könnten sich, wie die Stahlblechprofile 1, über ihre gesamte Länge gleichmäßig in der Breite derart verringern, dass die Profile an den Verbindungsstellen exakt aneinander fügbar sind.In the embodiment shown, the steel sheet profiles 21 have a continuously constant cross section. In the overlap area, therefore, there is slight bending of the sheet. The steel sheet profiles 21, like the steel sheet profiles 1, could be uniformly reduced in width over their entire length in such a way that the profiles are exactly joined to one another at the connection points.
