Definitions
- the present invention relates to a fall protection for persons, according to the preamble of claim 1.
- a fall protection for attachment to a flat roof is also by GB 2 351 789 A disclosed.
- fall arresters are used as anchor points on building roofs or on facades for personal security.
- the eyelet serves to receive a snap hook attached to the end of a safety rope that is part of the personal safety equipment of the person.
- the rod which carries the eyelet, is anchored by the foot to the ground.
- the foot can for this purpose have suitable positive anchoring means, which are introduced into the ground, such as dowels or the like. Since such anchoring means inevitably damage the ground, such as the roof of a flat roof, at the relevant point, alternative variants have been developed in which the fall protection is placed flat on the roof and glued or welded with this.
- the fall protection is placed flat on the roof and glued or welded with this.
- the applicant is proposed a fall protection whose foot strip-shaped lateral arms comprises, which extend from the base plate in a star shape in different spatial directions.
- These outriggers ensure that loads that are introduced into the footplate via the bar are distributed laterally from the footplate into the ground.
- the booms can be welded onto the roof membrane in a relatively simple manner.
- the fall protection comprises a securing plate, which is arranged above the foot plate and through which the rod is guided.
- This locking plate is provided with claws pointing to the ground. In the unloaded state, the free ends of the claws are loose on the ground or are located at a small distance above this.
- the backup plate supports the rod and prevents further tilting thereof. It is thus achieved in the event of a fall, a solid anchoring of the rod in the ground, which holds the fall protection substantially in position together with the ballast.
- the foot may be secured to the ground by any suitable means, such as a load acting on portions of the foot laterally disposed about the rod.
- the foot may be provided with side arms which extend from the bar over the ground and rest flat thereon while being weighted by ballast elements such as concrete slabs. The foot is thus held only by the ballast of the ballast elements on the ground. Damage to the ground by the claws of the backup plate thus takes place only in the event of a fall.
- the claws are formed by tabs which extend outwardly from the edges of the locking plate and are angled obliquely towards the ground.
- the backup plate is formed from a sheet metal blank.
- This provides a particularly simple and inexpensive way to produce the backup plate.
- the claws can simply be angled away from the edge of a punched-out security plate blank.
- the locking plate is substantially square, and from each corner of the square, two claws extend in mutually perpendicular directions which are angled at an angle of about 45 ° from the plane of the plate.
- the locking plate is held between two seated on the rod adjusting rings at a predetermined distance above the base plate.
- the collars can allow an adjustment in the height of the locking plate on the foot plate.
- the foot comprises lateral arms extending in a star shape from the foot plate in different spatial directions, the claws extending into the angular intervals between the arms.
- the foot further comprises a frame profile, in which the outer ends of the boom are enclosed.
- the frame profile includes a number of ballast plates, which are laid for weighting of the boom in the area bounded by the frame profile area.
- Fig. 1 shows a fall protection 10 for people who work at high altitudes, such as on a flat roof.
- the person to be secured may for this purpose with a snap hook, which is part of their personal protective equipment, engage a ring eyelet 12 which is secured to the upper end of a vertical bar 14.
- This rod 14 projects from a foot plate 16.
- the foot 18 of the fall protection 10 comprises in addition to the base plate 16 still lateral boom 20, which extend from the base plate 16 from star-shaped in different spatial directions and rest flat on the ground.
- the substrate is a horizontal flat roof, so that the boom 20 are also horizontal and the rod 14 is perpendicular thereto.
- the substrate is a horizontal flat roof, so that the boom 20 are also horizontal and the rod 14 is perpendicular thereto.
- a total of four boom 20 are present, which are arranged at angular intervals of 90 ° to each other.
- two arms 20 extend opposite one another from the base plate 16, and a further two arms 20 extend perpendicular to them.
- the boom 20 are formed as aluminum profiles. As in the Fig. 2 and 3 can be seen, the inner ends of the boom 20 are screwed by screws 22 to the base plate 16. Their outer ends are, as will be described in more detail below, enclosed in a square frame profile 52.
- a sleeve 24 is welded, in which the lower end of the rod 14 is inserted and secured therein.
- the attachment can be made by a threaded connection between the sleeve 24 and the rod 14.
- a securing plate 26 is arranged parallel to this.
- This backup plate 26 whose shape and function will be discussed in more detail below, has a central opening 28 through which the rod 14 is guided.
- On a portion of the rod 14 above the sleeve 24 to its attachment sit two collars, namely a lower collar 30 and an upper collar 32, between which the backup plate 26 is held at a predetermined distance above the base plate 16. The height of the securing plate 26 on the base plate 16 can thus be adjusted using the adjusting rings 30, 32.
- a tight fit of the collars 30, 32 on the rod 14 is achieved for example by clamping screws (not shown), which are guided laterally, ie transversely to the rod axis by the collars 30, 32 and with their help, the collars 30, 32 against the peripheral surface of the rod 14.
- the securing plate 26 is formed substantially square, with two claws 38 extend from each corner 34 of the square 36 in mutually perpendicular directions in space.
- a claw 38 vertically upward, namely approximately in the extension of the right edge 40 of the square 36, while another claw 38 perpendicular to this edge 40 in the extension of the upper, in substantially horizontally extending edge 42 of the square 36 extends.
- these claws 38 are perpendicular to each other, while, as in the 4 and 5 is clearly visible, down, that are angled obliquely from the plane of the square 36.
- the claws 38 are angled approximately at an angle of 45 ° from the plane of the plate.
- the angle can be chosen differently.
- the claws 38 are approximately harpoon-shaped at their ends 48 and have the contour of an arrowhead with lateral barbs.
- the backup plate 26 can be made in a simple manner from a sheet metal blank by punching and then bending the claws 38.
- the securing plate 26 is arranged on the foot 18 such that the claws 38 extend into the angular gaps 50 between two adjacent, mutually perpendicular arms 20.
- the ends 48 of the claws 38 are thus either directly above the ground or lie on this.
- Fig. 2 is clearly visible, in each case two mutually parallel claws 38 a boom 22, so that further in each angular gap 50 two mutually perpendicular claws 38 are angled from a corner 34 of the square 36 of the locking plate 26 downward.
- the backup plate 26 is the ends 48 of their claws 38 loose on the ground, or the ends 48 are located close to the Substrate, as described above. However, if such a lateral force acts on the upper end of the rod 14, as it is tilted, the claws 38 disposed on the side of the locking plate 26 corresponding to the tilting direction are buried in the ground and support the rod 14, so that one further tilting is prevented.
- the backup plate 26 thus ensures the load case, ie in particular in case of a fall, in which such a force acts on the eyelet 12, for sufficient stability.
- the burying of the ends 48 of the claws 38 in the ground is particularly favored if it is the substrate to relatively soft and vulnerable roofing membranes made of bitumen or foil.
- the ground must not be damaged to install the fall protection 10, but damage takes place only when the above-described crash occurs, in which the pointed ends 48 of the claws 38 can dig into the soft ground.
- the foot 18 of the fall protection 10 further includes a square frame profile 52, the corners 54 surround the outer ends of the boom 20.
- the cantilevers 20 thus form the diagonals of this frame profile 52, and adjacent cantilevers 20 enclose with one side 56 of the frame profile 52 a triangular surface which corresponds to the already mentioned angular gap 50 between the cantilevers 20.
- the area enclosed by the frame profile 52 surface area may be designed with a weather-resistant network.
- the frame profile 52 lies directly on the ground. It is intended to receive ballast plates 58, which can be individually laid side by side in the square area bounded by the frame profile 52, such that the edges of the ballast plates 58 are bordered by the sides 56 of the frame profile 52 and prevented from sliding sideways.
- ballast plates 58 In Fig. 1 only one of the ballast plates 58 is shown, in which it may be conventional concrete slabs, so as to commercially available paving slabs.
- the ballast plates 58 rest on the upper sides of the arms 20 and thus form a load on the foot 18, which prevents the foot 18 from slipping sideways on the roof skin.
- the fall protection 10 so only by the load of the ballast plates 58 on the Secured underground, so that no further fasteners are required to hold the fall protection 10 in position.
- This offers the advantage that the installation of the fall protection 10 of the ground, so in particular a roof or foil, must not be damaged.
- the securing plate 26 forms an additional safeguard, which prevents tilting of the rod 14.
Description
Die vorliegende Erfindung betrifft eine Absturzsicherung für Personen, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a fall protection for persons, according to the preamble of claim 1.
Eine derartige Absturzsicherung ist in
Eine Absturzsicherung zur Anbringung auf einem Flachdach ist ferner durch
Solche Absturzsicherungen werden als Ankerpunkte auf Gebäudedächern oder an Fassaden zur Personensicherung verwendet. Die Ringöse dient zur Aufnahme eines Karabinerhakens, der am Ende eines Sicherungsseils angebracht ist, das zur persönlichen Sicherheitsausrüstung der Person gehört. Der Stab, der die Öse trägt, ist durch den Fuß am Untergrund verankert.Such fall arresters are used as anchor points on building roofs or on facades for personal security. The eyelet serves to receive a snap hook attached to the end of a safety rope that is part of the personal safety equipment of the person. The rod, which carries the eyelet, is anchored by the foot to the ground.
Der Fuß kann zu diesem Zweck geeignete formschlüssige Verankerungsmittel aufweisen, die in den Untergrund eingebracht werden, wie etwa Dübel oder dergleichen. Da solche Verankerungsmittel zwangsläufig den Untergrund, wie etwa die Dachhaut eines Flachdachs, an der betreffenden Stelle beschädigen, sind auch alternative Varianten entwickelt worden, in welchen die Absturzsicherung flach auf die Dachhaut aufgesetzt und mit dieser verklebt oder verschweißt wird. In dem deutschen Gebrauchsmuster
Es existieren jedoch Anwendungsfälle, in denen ein solches Aufschweißen nicht möglich oder nicht erwünscht ist. Grundsätzlich ist es in diesem Fall möglich, den Fuß mit den Auslegern mit einer Auflast wie etwa großflächig darauf verteilten Betonplatten zu belasten, so dass er sich nicht ohne weiteres auf dem Untergrund verschieben kann. Die Absturzsicherung wird also lediglich durch die auf den Fuß wirkende Auflast auf dem Untergrund gehalten, und letzterer bleibt völlig unbeeinträchtigt. Überdies würde eine solche Absturzsicherung den Vorteil bieten, dass sie sich rückstandsfrei bei Bedarf wieder vom Untergrund entfernen lässt. Allerdings besteht eine Schwierigkeit darin, die Absturzsicherung so auszulegen, dass sie auch die im Absturzfall auftretenden ruckartigen Lasten aufnehmen und zuverlässig in den Untergrund ableiten kann. Es ist daher bisher keine Absturzsicherung bekannt, die im Belastungsfall lediglich durch eine auf den Fuß wirkende Auflast ohne wesentliche Positionsänderung auf dem Untergrund gehalten wird.However, there are applications in which such welding is not possible or not desirable. Basically, it is possible in this case to load the foot with the jibs with a ballast such as concrete slabs distributed over a large area, so that it can not easily move on the ground. The fall protection is thus held only by the load acting on the foot on the ground, and the latter is completely unimpaired. Moreover, such a fall protection would offer the advantage that it can be removed without residue from the substrate when needed. However, there is a difficulty in designing the fall protection so that it can absorb the jerky loads occurring in the event of a fall and reliably dissipate them into the ground. So far there is no fall protection known, which is held in the case of load only by acting on the foot load without significant change in position on the ground.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Absturzsicherung der eingangs genannten Art zu schaffen, die lediglich durch eine auf den Fuß wirkende Auflast in ihrer Position gehalten wird, sich jedoch auch bei den im Absturzfall in den Fuß eingeleiteten hohen Lasten nicht wesentlich auf dem Untergrund verschiebt und somit ein ausreichendes Maß an Sicherheit bietet.It is therefore an object of the present invention to provide a fall protection of the type mentioned, which is held only by a load acting on the foot ballast in position, but not significantly on the in the fall in the foot introduced high loads on the Substrate moves and thus provides a sufficient level of security.
Diese Aufgabe wird erfindungsgemäß durch eine Absturzsicherung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a fall protection with the features of claim 1.
Erfindungsgemäß umfasst die Absturzsicherung eine Sicherungsplatte, die über der Fußplatte angeordnet ist und durch welche der Stab geführt ist. Diese Sicherungsplatte ist mit Krallen versehen, die zum Untergrund weisen. Im unbelasteten Zustand liegen die freien Enden der Krallen lose auf dem Untergrund auf oder befinden sich in geringem Abstand über diesem. Im Absturzfall bewirkt die in den Stab eingeleitete seitliche Last ein ruckartiges Verkippen des Stabs, was dazu führt, dass sich die Krallen der Sicherungsplatte an der Seite, zu welcher der Stab sich neigt, in den Untergrund eingraben. Die Sicherungsplatte stützt dann den Stab und verhindert ein weiteres Kippen desselben. Es wird somit im Absturzfall eine feste Verankerung des Stabs im Untergrund erreicht, die gemeinsam mit der Auflast die Absturzsicherung im wesentlichen in ihrer Position hält.According to the invention, the fall protection comprises a securing plate, which is arranged above the foot plate and through which the rod is guided. This locking plate is provided with claws pointing to the ground. In the unloaded state, the free ends of the claws are loose on the ground or are located at a small distance above this. In the event of a fall initiated in the rod lateral Load a jerky tilting of the rod, causing the claws of the locking plate to dig into the ground at the side to which the rod tilts. The backup plate then supports the rod and prevents further tilting thereof. It is thus achieved in the event of a fall, a solid anchoring of the rod in the ground, which holds the fall protection substantially in position together with the ballast.
Der Fuß kann durch geeignete Mittel auf dem Untergrund gesichert werden, beispielsweise durch eine Auflast, die auf seitlich um den Stab herum angeordnete Teile des Fußes wirkt. Der Fuß kann beispielsweise, wie oben bereits beschrieben, mit seitlichen Auslegern versehen sein, die sich vom Stab aus über den Untergrund erstrecken und flach auf diesem aufliegen, während sie durch Ballastelemente wie etwa Betonplatten beschwert sind. Der Fuß wird also lediglich durch die Auflast der Ballastelemente auf dem Untergrund gehalten. Eine Beschädigung des Untergrundes durch die Krallen der Sicherungsplatte findet also lediglich im Absturzfall statt.The foot may be secured to the ground by any suitable means, such as a load acting on portions of the foot laterally disposed about the rod. For example, as described above, the foot may be provided with side arms which extend from the bar over the ground and rest flat thereon while being weighted by ballast elements such as concrete slabs. The foot is thus held only by the ballast of the ballast elements on the ground. Damage to the ground by the claws of the backup plate thus takes place only in the event of a fall.
Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung werden die Krallen durch Laschen gebildet, die sich von den Rändern der Sicherungsplatte nach außen erstrecken und zum Untergrund hin schräg abgewinkelt sind.According to a preferred embodiment of the present invention, the claws are formed by tabs which extend outwardly from the edges of the locking plate and are angled obliquely towards the ground.
Vorzugsweise wird die Sicherungsplatte aus einem Blechzuschnitt gebildet. Dies bietet eine besonders einfache und preiswerte Möglichkeit zur Herstellung der Sicherungsplatte. Die Krallen können in diesem Fall einfach vom Rand eines ausgestanzten Sicherungsplattenzuschnitts abgewinkelt werden.Preferably, the backup plate is formed from a sheet metal blank. This provides a particularly simple and inexpensive way to produce the backup plate. In this case, the claws can simply be angled away from the edge of a punched-out security plate blank.
Weiter vorzugsweise ist die Sicherungsplatte im wesentlichen quadratisch, und von jeder Ecke des Quadrats erstrecken sich zwei Krallen in zueinander senkrechte Richtungen, die in einem Winkel von etwa 45° von der Plattenebene abgewinkelt sind.More preferably, the locking plate is substantially square, and from each corner of the square, two claws extend in mutually perpendicular directions which are angled at an angle of about 45 ° from the plane of the plate.
Weiter vorzugsweise wird die Sicherungsplatte zwischen zwei auf dem Stab sitzenden Stellringen in einem vorbestimmten Abstand über der Fußplatte gehalten. Die Stellringe können eine Justage in der Höhe der Sicherungsplatte über der Fußplatte gestatten.Further preferably, the locking plate is held between two seated on the rod adjusting rings at a predetermined distance above the base plate. The collars can allow an adjustment in the height of the locking plate on the foot plate.
Gemäß der vorliegenden Erfindung umfasst der Fuß seitliche Ausleger, die sich von der Fußplatte aus sternförmig in unterschiedliche Raumrichtungen erstrecken, wobei sich die Krallen in die Winkelzwischenräume zwischen den Auslegern erstrecken.According to the present invention, the foot comprises lateral arms extending in a star shape from the foot plate in different spatial directions, the claws extending into the angular intervals between the arms.
Gemäß einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung umfasst der Fuß ferner ein Rahmenprofil, in welches die äußeren Enden der Ausleger eingefasst sind.According to another preferred embodiment of the present invention, the foot further comprises a frame profile, in which the outer ends of the boom are enclosed.
Weiter vorzugsweise fasst das Rahmenprofil eine Anzahl von Ballastplatten ein, die zur Beschwerung der Ausleger in dem vom Rahmenprofil umgrenzten Flächenbereich verlegt sind.Further preferably, the frame profile includes a number of ballast plates, which are laid for weighting of the boom in the area bounded by the frame profile area.

Die Ausleger 20 sind als Aluminiumprofile ausgebildet. Wie in den
Auf die Oberseite der Fußplatte 16 ist eine Hülse 24 aufgeschweißt, in welche das untere Ende des Stabes 14 eingesteckt und darin befestigt ist. Die Befestigung kann durch eine Gewindeverbindung zwischen der Hülse 24 und dem Stab 14 erfolgen.On the top of the
Über der Fußplatte 16 ist eine Sicherungsplatte 26 parallel zu dieser angeordnet. Diese Sicherungsplatte 26, auf deren Form und Funktion weiter unten noch näher eingegangen werden soll, weist eine zentrale Öffnung 28 auf, durch welche der Stab 14 geführt ist. Auf einem Abschnitt des Stabs 14 oberhalb der Hülse 24 zu seiner Befestigung sitzen zwei Stellringe, nämlich ein unterer Stellring 30 und ein oberer Stellring 32, zwischen denen die Sicherungsplatte 26 in einem vorbestimmten Abstand über der Fußplatte 16 gehalten wird. Die Höhe der Sicherungsplatte 26 über der Fußplatte 16 lässt sich somit mit Hilfe der Stellringe 30, 32 einstellen. Ein fester Sitz der Stellringe 30, 32 auf dem Stab 14 wird beispielsweise durch Klemmschrauben erreicht (nicht dargestellt), die seitlich, also quer zur Stabachse durch die Stellringe 30, 32 geführt sind und mit deren Hilfe sich die Stellringe 30, 32 gegen die Umfangsoberfläche des Stabs 14 klemmen lassen.Over the

Wird der Stab 14 nicht seitlich belastet, also durch eine an der Ringöse 12 angreifende Kraft seitlich gegenüber der Grundplatte 16 gekippt, liegt die Sicherungsplatte 26 mit den Enden 48 ihrer Krallen 38 lose auf dem Untergrund auf, oder die Enden 48 befinden sich dicht über dem Untergrund, wie vorstehend beschrieben. Wirkt jedoch eine solche seitliche Kraft auf das obere Ende des Stabs 14, so werden bei dessen Verkippen die Krallen 38, die an der Seite der Sicherungsplatte 26 angeordnet sind, die der Kipprichtung entspricht, in den Untergrund eingegraben und stützen den Stab 14, so dass ein weiteres Verkippen verhindert wird. Die Sicherungsplatte 26 sorgt also im Belastungsfall, also insbesondere im Sturzfall, in welchem eine solche Kraft auf die Ringöse 12 wirkt, für eine ausreichende Stabilität. Das Eingraben der Enden 48 der Krallen 38 in den Untergrund wird insbesondere begünstigt, wenn es sich bei dem Untergrund um relativ weiche und verletzbare Dachbahnen aus Bitumen oder Folie handelt.
