ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a device for cleaning the tubular frames of scaffolding.
2. Description of the Related Art
In building renovation, for example exterior rendering, it is impossible to avoid fouling the tubular frames of scaffolding with rendering mortar, especially sprayed rendering. The mortar then adheres to the scaf folding pipe and at a given time must be removed. This is however a tedious and time-consuming activity. The adhering dried mortar droppings are generally knocked off with a hammer and/or scraped off with a trowel; this often leads to damage of the galvanized surface of the scaffolding pipes.
SUMMARY OF THE INVENITION
The object of the invention is to devise a device with which adhering mortar droppings and other dirt can be carefully and easily removed from scaffolding pipes both with the scaffolding erected and also in the disassembled state.
