Grandstand with floors accessed by steps, and supported by scaffolding

摘要

The grandstand is supported by scaffolding, especially tubular scaffolding, and has at least one row of seating (5-7) arranged on more than one floor (2-4) which can be accessed by steps (47-49). The supporting structure has scaffolding uprights (8-10), and crossbars (15-17) which are supported on the latter by brackets (11,12) in a predetermined vertical grid pattern (H). The seats have a layer of boarding on crossbars, whose uprights have brackets which correspond with the vertical grid pattern, in order to accept boards for a walkway (44-46) in front of each seating row. The grandstand also has crossbars (50-52) for the steps which link the floor layers, and which have a continuous layer of boarding. A standing surface is arranged above the walkway, in front of each row of seating, and corresponds with a vertical grid pattern (h) which is smaller in comparison with that of the seating.
