Abstract

1. A transportable anchorage device for the anchorage of a safety harness on dangerous, essentially flat work places, such as flat roofs, characterized by a flexible large sized container (2) with a large base surface (3) in proportion to its height and with a fitting (spigot 7) for the connection of a water conduit as well as at least one mounting for the connection of the safety harness.

Description

Die Erfindung richtet sich auf eine transportable Vorrichtung zum Verankern eines Sicherheitsgeschirrs an gefährlichen, im wesentlichen ebenen Arbeitsstellen, wie Flachdächern od.dgl..The invention is directed to a transportable device for anchoring a safety harness at dangerous, essentially flat work places, such as flat roofs or the like.

Die Arbeitssicherheit und die hierauf bedachten Unfallverhütungsvorschriften verlangen bei Arbeiten auf erhöhten Arbeitsstellen, wie z.B. auf Flachdächern od.dgl., insbesondere bei einer 5 m überschreitenden Randhöhe einen ausreichenden Schutz gegen Absturz der mit diesen Arbeiten betrauten Personen. Im allgemeinen ist ein Anseilschutz erforderlich, wozu die verschiedensten Sicherheitsgeschirre dienen. Diese verlangen sämtlich einen Anschlagpunkt auf der erhöhten Fläche. Bei Flachdächern od.dgl. fehlen solche Anschlagpunkte im allgemeinen. Zum Anschlag der Sicherheitsgeschirre dienende Anker müßten eigens angebracht werden und erfordern einen hohen Kostenaufwand. Nach Fertigstellung der Arbeiten würden solche Anker störend zurückbleiben und der Korrosion durch Witterungseinflüsse ausgesetzt sein, so daß sie bei einem späteren Anwendungsfall möglicherweise gar nicht mehr brauchbar wären und eine eigene Unfallgefahr bedeuteten. Ein solcher Anschlagpunkt muß in Verbindung mit einem Falldämpfer eine horizontal wirkende Kraft von 750 kp aufnehmen können.Occupational safety and the related accident prevention regulations require adequate protection against falling of the persons entrusted with this work when working on elevated workplaces, such as flat roofs or the like, especially if the edge height exceeds 5 m. Rope protection is generally required, for which a variety of safety harnesses are used. These all require an anchor point on the raised surface. For flat roofs or the like. Such anchor points are generally missing. Anchors serving to secure the safety harnesses would have to be attached separately and require a high cost. After completion of the work, such anchors would remain disruptive and be exposed to corrosion from the weather, so that they would possibly no longer be usable in a later application and would represent a risk of an accident. Such an attachment point must absorb a horizontally acting force of 750 kp in connection with a fall damper can.

Aus den geschilderten Schwierigkeiten erwächst das Bedürfnis nach einer Verankerungsvorrichtung für Sicherheitsgeschirre, die an beliebigen Arbeitsstellen ohne große Schwierigkeiten aufgestellt und nach Gebrauch wieder entfernt werden kann. Gegenüber den bekannten Vorrichtungen richtet sich die Erfindung auf eine transportable Verankerungsvorrichtung. In Ausgestaltung dieses allgemeinsten Gedankens zeichnet sich die Vorrichtung aus durch einen flexiblen großformatigen Behälter mit im Verhältnis zu seiner Höhe großer Grundfläche und mit einer Armatur zum Anschluß an eine Wasserleitung sowie wenigstens einer Halterung zum Anschlagen des Sicherheitsgeschirrs.From the difficulties described, there arises a need for an anchoring device for safety harnesses, which can be set up at any work place without great difficulty and removed again after use. Compared to the known devices, the invention is directed to a transportable anchoring device. In an embodiment of this most general idea, the device is characterized by a flexible, large-format container with a large base area in relation to its height and with a fitting for connection to a water pipe and at least one holder for attaching the safety harness.

Ein solcher Behälter wird am Gebrauchsort mit Wasser gefüllt, was entsprechend den üblichen Gegebenheiten mit einem einfachen Wasserschlauch ohne weiteres möglich ist. Daraus folgt aber andererseits, daß ein solcher Behälter nach Ablassen des Wassers jederzeit transportabel ist und an einem neuen Arbeitsplatz wieder aufgestellt werden kann. Die im Verhältnis zur Behälterhöhe große Grundfläche sorgt für die erforderliche Haftung auf der Unterlage. Ein solcher Behälter ist, ausgehend von einem Fassungsvermögen leicht zu berechnen, damit die den Vorschriften entsprechende Kraft erreicht wird. Eine unsachgemäße Handhabung ist praktisch ausgeschlossen, weil jedermann den Füllzustand einer solchen Vorrichtung ohne weiteres erkennt, d.h. also, daß ein nur teilweises Füllen des Behälters einer Aufsichtsperson sofort auffällt und mithin ein solcher Fehler abgestellt werden kann.Such a container is filled with water at the place of use, which is easily possible according to the usual conditions with a simple water hose. On the other hand, it follows that such a container can be transported at any time after the water has been drained and can be set up again at a new workplace. The large footprint in relation to the container height ensures the necessary adhesion to the surface. Such a container is easy to calculate on the basis of a capacity so that the force corresponding to the regulations is achieved. Improper handling is practically impossible because everyone can easily recognize the filling status of such a device, i.e. So that a partial filling of the container of a supervisor is immediately noticeable and thus such a mistake can be remedied.

Der Behälter der erfindungsgemäßen Vorrichtung kann aus PVC-beschichtetem hochfestem Gewebe bestehen, welches an sich zur Herstellung von Behältern bereits bekannt ist. Es liegt im Rahmen der Erfindung, daß der Behälter einen umlaufenden Saum und in diesem angeordnete Anschlagösen für die Sicherheitsgeschirre aufweist. Ein solcher Saum ist bei derartigen Behältern vielfach ohnehin vorhanden. Er braucht lediglich mit den notwendigen Ösen versehen zu werden. Der Saum ist darüber hinaus im allgemeinen gegenüber der Behälterwand verstärkt, so daß die notwendige Festigkeit von vornherein gewährleistet ist.The container of the device according to the invention can consist of PVC-coated high-strength fabric, which is already known per se for the production of containers. It is within the scope of the invention that the container has a circumferential hem and stop loops for safety harnesses arranged therein. Such a hem is already present in many cases with such containers. It only needs to be provided with the necessary eyelets. The hem is also generally reinforced against the container wall, so that the necessary strength is guaranteed from the outset.

Als besonders vorteilhaft hat es sich erwiesen, die Anordnung so zu treffen, daß die Auflagerfläche des Behälters einen hohen Reibungskoeffizienten aufweist. Das heißt m.a.W., daß zumindest der Behälterboden an seiner Außenseite eine reibungserhöhende Oberfläche aufweist.It has proven to be particularly advantageous to make the arrangement such that the bearing surface of the container has a high coefficient of friction. This means that at least the bottom of the container has a friction-increasing surface on its outside.

In weiterer Ausgestaltung der Erfindung ist der Behälter mit einem Sicherheitsventil und ggf. auch einem Ablaßventil versehen. Bei einem Fassungsvermögen des Behälters von 1000 1 und einem Reibungskoeffizienten von 0,75 - 0,80 lassen sich ohne weiteres horizontale Kräfte zwischen 750 bis 800 kp aufnehmen. Das Ablaßventil kann ggf. zum Entlüften beim Füllvorgang dienen. Findet diese Verankerungsvorrichtung bei Arbeiten auf einem Dach Verwendung, kann nach bedarf das Wasser jederzeit aus dem Behälter abgelassen werden und das Wasser frei auf dem Dach ablaufen.In a further embodiment of the invention, the container is provided with a safety valve and possibly also a drain valve. With a container capacity of 1000 l and a coefficient of friction of 0.75 - 0.80, horizontal forces between 750 and 800 kp can easily be absorbed. The drain valve can possibly be used for venting during the filling process. If this anchoring device is used when working on a roof, the water can be drained from the container at any time and the water can run off freely on the roof.

Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung einer bevorzugten Ausführungsform der Erfindung sowie anhand der Zeichnung. Hierbei zeigen:

  • Fig. 1 in perspektivischer Ansicht eine Verankerungsvorrichtung in Gebrauchsstellung und
  • Fig. 2 ein Detail in vergrößerter Schnittdarstellung.
Further features, details and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. Here show:
  • Fig. 1 is a perspective view of an anchoring device in the use position and
  • Fig. 2 shows a detail in an enlarged sectional view.

Die Wand 1 des Behälters 2 besteht aus einem beschichteten hochfesten Gewebe. Ggf. kann der Boden 10 noch eigens verstärkt sein bzw. kann seine Auflagerfläche 3 in einer reibungserhöhenden Weise ausgebildet sein. Wandung 1 und Boden 10 sind im Bereich eines umlaufenden Saumes 4 miteinander verbunden, im allgemeinen verschweißt. In diesen Saum 4 sind in regelmäßigen Abständen Ösen 5 angeordnet, die zum Befestigen von Sicherheitsgeschirren, beispielsweise mittels eines Karabinerhakens oder Sicherheitshakens dienen.The wall 1 of the container 2 consists of a coated high-strength fabric. Possibly. can the bottom 10 be reinforced or its support surface 3 in a row be trained to increase exercise. Wall 1 and bottom 10 are connected to one another in the region of a circumferential seam 4, generally welded. In this hem 4 eyelets 5 are arranged at regular intervals, which are used to fasten safety harnesses, for example by means of a snap hook or safety hook.

Der Behälter 2 weist im wesentlichen Quaderform und eine rechteckige Grundfläche auf. An der Stirnseite 6 ist ein Füllstutzen 7 angeordnet, der ein Absperrventil 8 aufweist, welches nur schematisch dargestellt ist. Dieser Stutzen 7 weist eine Schnellkupplung oder Gewindekupplung zum Anschluß eines Wasserschlauchs auf. Ein Sicherheitsventil, welches im einzelnen nicht dargestellt ist, dient dem Schutz vor Überbelastung beim Füllen. Der Behälter 2, insbesondere aber der Boden 10, sind unter Vermeidung scharfer Kanten, Rillen od.dgl. ausgebildet, um Beschädigungen, z.B. durch Kantenpressung, an der Auflagerfläche, ggf. dem Flachdach, zu vermeiden.The container 2 has a substantially cuboid shape and a rectangular base. A filler neck 7 is arranged on the end face 6 and has a shut-off valve 8, which is only shown schematically. This nozzle 7 has a quick coupling or threaded coupling for connecting a water hose. A safety valve, which is not shown in detail, serves to protect against overloading when filling. The container 2, but especially the bottom 10, or the like, avoiding sharp edges, grooves or the like. trained to prevent damage e.g. by edge pressure, on the support surface, possibly on the flat roof.

Die Ösen 5 sind im Saum 4 derart ausgelegt, daß sie unbeschadet eine Belastung von mindestens 750 kp aushalten. Ist die Grundfläche des Behälters etwa 1 m x 2 m groß, ergibt sich eine Belastung für die Unterlage, ggf. das Flachdach, von 0,05 kp/cm2. Überträgt man diese Belastung auf eine Wärmedämmschicht etwa aus Styropor des Typs PS 20, beträgt die nach der entsprechenden Norm zulässige Druckspannung bei 10 % Stauchung 1,0 - 1,4 kp/cm2. Daraus folgt, daß die Anwendung einer solchen Verankerungsvorrichtung selbst für die Wärmedämmschicht eines Flachdachs unschädlich ist.The eyelets 5 are designed in the hem 4 such that they can withstand a load of at least 750 kp without damage. If the base area of the container is approximately 1 mx 2 m, the load on the base, possibly the flat roof, is 0.05 kp / cm 2 the permissible compressive stress at 10% compression 1.0-1.4 kp / cm 2. It follows that the use of such anchoring device is harmless even for the thermal insulation layer of a flat roof.
