Description

Dachdeckerschutzgerüst Die Erfindung betrifft ein Dachdeckerschutzgerüst aus einem den Dachsparren gabelig umfassenden Tragarm mit einem festen und einem verstellbaren W iderlager.Roofer protection scaffold The invention relates to a roofer protection scaffold from a forked support arm encompassing the rafters with one fixed and one adjustable abutment.

Das Neue besteht darin, daß über die den Dachsparren umfassenden Gabelarme ein bügelförmiges, mit abwärts gerichteten Bügelschenkeln, die Langschlitze besitzen, versehenes Widerlager aufschiebbar und in Rasten der Gabelenden einlegbar sowie durch Keile feststellbar ist.The new thing is that the fork arms surrounding the rafters a bow-shaped, with downwardly directed bow legs that have long slots, provided abutment can be pushed on and inserted in notches of the fork ends as well can be determined by wedges.

Hierdurch wird erreicht, daß sich das mit einer scharfen Kante versehene, verstellbare Widerlager fest gegen die Unterseite des schrägen Dachsparrens anlegt, etwas in diesen eindringt und somit durch eine stärkere Festklemmung ein Abrutschen des Gerüstes verhindert und eine größere Sicherheit in der Auslösung des Widerlagers aus den Rasten der Tragarmgabelenden erzielt wird.This ensures that the one provided with a sharp edge, adjustable abutment firmly against the underside of the sloping rafter, something penetrates into this and thus slipping due to a stronger clamping of the scaffolding prevented and greater security in the triggering of the abutment is achieved from the notches of the support arm fork ends.

Auf der Zeichnung ist ein Dachdeckerschutzgerüst nach der Erfindung in einem Ausführungsbeispiel in Abb. r in der Seitenansicht dargestellt, während die Abb. a und 3 den Gerüsttragarm als Einzelteil in der Seitenansicht und in der Rückansicht veranschaulichen.On the drawing is a roofer protection scaffold according to the invention in one embodiment shown in Fig. r in the side view, while Figs. a and 3 the scaffold support arm as an individual part in the side view and in the Illustrate rear view.

Zum Tragen des Laufbrettes a dient der an dem Dachsparren b freiauslegend aufgehängte Laufbretträger oder Tragarm c, welcher an seinem einen Ende gegabelt ist und mit seinen Schenkeln d-d', an welchen die an den Schrägflächen des Dachsparrens anliegenden Widerlager e und f befestigt sind, den Dachsparren b umfaßt.The running board a is supported by the running board carrier or support arm c, which is suspended from the rafter b and is bifurcated at one end and with its legs d-d ', to which the abutments e and f, which lie against the inclined surfaces of the rafter, are attached, includes the rafters b.

Am anderen Ende des Tragarmes c ist die Brustwehr g angelenkt, welche durch eine am Laufbretträger angreifende Zugstange h gehalten wird. Als festes am Dachsparren sich anlegendes Widerlager dient beispielsweise ein Bolzen e, während das zweite verstellbare Widerlager f bügelförmig mit abwärts gerichteten Bügelschenkeln f' und f" gestaltet ist, die Langschlitze i-i besitzen und auf die Tragarmschenkel d-d' aufschiebbar sind. Die hintereinanderliegenden Rasten k der Tragarmschenkel d-d' dienen zum Einlegen der Bügelschenkel f' und f" und können durch einen Keil L gesichert werden.At the other end of the support arm c, the parapet g is hinged, which is held by a pull rod h engaging the running board support. A bolt e, for example, serves as a fixed abutment resting on the rafters, while the second adjustable abutment f is bow-shaped with downwardly directed bow legs f ' and f " , which have long slots ii and can be pushed onto the support arm legs dd' Support arm legs dd 'are used to insert the bracket legs f' and f " and can be secured by a wedge L.

Zum Umsetzen des auf den Dachsparren aufgebrachten Schutzgerüstes ist es nur notwendig, die Tragarme c am vorderen Ende anzuheben, wobei die Widerlager e und f von dem Dachsparren b abgehoben und auf diesem entlang verschoben werden. Nach dem Zurückschwingen legen sich die Tragarme c mit ihren Widerlagern e und f wieder an den Dachsparren an und werden, belastet durch das Eigengewicht des Gerüstes und durch die Nutzlast, am Dachsparren festgeklemmt. Die zwischen dem Dachsparren und den Widerlagern auftretende Reibung ist so groß, daß ein Rutschen des außerdem einwandfrei gesicherten Gerüstes vollkommen ausgeschlossen ist.For moving the protective scaffolding attached to the rafters it is only necessary to lift the support arms c at the front end, with the abutment e and f are lifted off the rafter b and moved along it. After swinging back, the support arms c lay down with their abutments e and f back to the rafters and are burdened by the weight of the scaffolding itself and by the payload, clamped to the rafter. The one between the rafters and the abutments occurring friction is so great that a slipping of the also perfectly secured scaffolding is completely excluded.
