Scaffolding

_ ■

The jirfindung refers to a scaffolding, in particular for the construction or repair of an overhead building. In particular the invention is intended as scaffolding for the Erection of masonry or other walls,? / O der Worker must subsequently work at different heights and accordingly move the scaffolding in the direction of the height. must be adjustable »

The main purpose of the finding is to raise the scaffolding platform of the Worker to be able to adjust at different altitudes without the platform or the building material during the The setting of the scaffolding need to be grounded away

The scaffolding according to the invention has two vertical supports, which are spanned by a winch beam, which each otütze can be removed, whereby from the ', Yinde des Winch support two cables to the winch support ends and extend down along the vertical supports to another beam which carries the scaffolding platforms and so it can be moved up and down by means of the winch

The invention is explained on the basis of the drawings «

The vertical supports are about four feet long and close to a tapered lower part which is inserted into the upper end of an underlying support. The vertical supports are connected to one another by means of side bracing, and each side spanning (II ¹ Ig ₀ S) is a G-itter carrier whose upper and lower tubular belts 63 »64 flattened linden 63a, 64a have (Pig, 7 and 8) with lateral extensions 65,66 (]? ige9) s AEIE ^IRL certain slots 61 The lugs have shoulders 65a, 66a which, as described below, hold the straps at a certain distance from the vertical supports.

Conversely, the wedge can also can be rotated into a horizontal position shown in full lines in FIG. 7 and 8 o The hand lever 68 runs perpendicular to the length extension of the wedge 67 and is extended to one side from the wedge. In the vertical position of the wedge, the hand lever swings downwards by gravity and the side bracing is jammed by friction with the vertical support facilitated, as this does not require very stubs and udders.

At a distance above each carrier 75 there is an elongated winch carrier 90 ₉ which is detachably attached to the vertical supports 60 with its ends. A winch 94 is rotatably mounted in vertical arms 92 in the middle of the carrier 90 · The shaft and the gear are 95? 96, 97 designated.
