| 摘要 |
<p>The present invention relates to a stair step nosing (1) that comprises a functional member (2) made of a resilient material as well as a horizontal fixation member (4) and a vertical fixation member (3) which are connected to the rear (6) and lower (5) surfaces of said functional member (2), respectively. The thickness H of the working member and the elasticity module E of the resilient material are determined by the relations H > h + h1 and E≤H x k, where h represents the thickness of step nosing material in meters, h1 represents the thickness of the horizontal fixation member in meters, and k = 10?11 in n/m3¿.</p> |
