Zusammenfassung: | To provide a scaffolding member which allows a worker to early discover cracks on the surface so that it is possible to improve the safety of the worker.SOLUTION: A scaffolding member (tread 11) comprises an inner layer 12 which is a molded resin, and an outer layer 13 which is layered outside the inner layer 12 and is made of reinforced fiber. The inner layer 12 has a first layer on the surface on which the outer layer 13 is layered. The outer layer 13 has a second layer on its outer surface. Color difference between the first color of the inner layer 12 and the second color on the outer layer 13 is 40 or more in CIELab color space. This arrangement makes it easier for a worker to visually recognize when there are cracks on the outer layer 13. As a result, it is possible to repair or exchange the cracked tread 11.SELECTED DRAWING: Figure 1
【課題】表面に亀裂が生じても早期に発見でき、作業員の安全性を向上させることができる。【解決手段】足場材(踏板11)は、成形樹脂である内層12と、前記内層12の外側に積層され、強化繊維である外層13とを備える。前記内層12は、前記外層13が積層された表面に第1色を有している。前記外層13は、外側の表面に第2色を有している。前記内層12の第1色と前記外層13の第2色との色差は、CIELab色空間において40以上である。これにより、外層13に亀裂が生じた際、作業員は、亀裂を視認しやすくなる。その結果、亀裂の生じた踏板11を修復でき、または、交換することができる。【選択図】図1 |
