<p>The trunk, which is supported on an elastic material like neopren pads (3, 4) is put in place as soon as the carcassing is finished and serves as stairs during the continued building process. When the rough work is finished, prefabricated steps (2) are installed on elastic material like neopren pads (5, 5'). The steps are bolted and neopren pads are inserted between the heads of the bolts (6) and the trunk (1). There is considerable clearance between the bolts (6) and the trunk (1) and the bolt (6) is at an angle with the step (2) for the purpose of pulling the step into good contact and for reducing the vertical component of the forces transmitted through the bolt.</p> |
