    • A cover plate system for a gap (15) between two structural members (10, 20) is provided. The system includes an elongated cover (30) that extends across the gap (15) from a first structural member (10) to a second, spaced-apart structural member (20). The cover plate system further includes damped spring anchors (40) for engaging the cover plate (30) to an underlying structural member (10) and dampers (50, 60) for absorbing energy imparted to the cover plate (30) by vehicular traffic. The cover plate system minimizes the strain energy that is absorbed by the cover plate (30), which results in less cover plate slapping and bouncing during operation.
    • 提供了一种用于两个结构构件(10,20)之间的间隙(15)的盖板系统。 该系统包括从第一结构构件(10)延伸穿过间隙(15)延伸到第二间隔开的结构构件(20)的细长盖(30)。 盖板系统还包括阻尼弹簧锚固件(40),用于将盖板(30)接合到下面的结构构件(10)和阻尼器(50,60),用于吸收由车辆行驶传递给盖板(30)的能量。 盖板系统使由盖板(30)吸收的应变能最小化,这在操作期间导致较少的盖板打击和弹跳。
