摘要

The walkway has hollow frames (4) and multiple supporting plates (5), which are fastened in the framework and possesses one end with tread part (51) and another end with a bent part (52). The latter end is diagonally arranged relative to the tread part. The tread part of each supporting plate is attached over the bent part of the neighboring supporting plate and partially covers it. The supporting plates are at a distance from each other, in order to define multiple channels (53) between tread part of each supporting plate and the neighboring bent part of each supporting plate.
