本发明涉及适用于公路和桥梁的车辆防撞设施， 具体地， 涉及一种单波 梁护栏板及单波梁钢护栏。 背景技术
随着我国公路建设和交通事业的快速发展， 行车安全面临着严峻形势， 防撞护栏作为一种安全设施， 对公路和桥梁的行车安全发挥着重要的防护作 用。
一般地， 防撞护栏主要包括刚性护栏、 半刚性护栏和柔性护栏三种。 其 中， 刚性护栏以混凝土护栏为主， 主要有新泽西护栏和组合式护栏， 这种混 凝土护栏的刚度过大， 缓冲和吸收车辆动能的能力小， 当车辆重心较高时， 在碰撞后容易翻越混凝土护栏； 当车辆重心较低时， 在碰撞后容易造成内侧 翻。 半刚性护栏以波形梁护栏和梁柱式护栏为主， 波形梁护栏分为两波护栏 和三波护栏， 这种波形梁护栏需要依靠钢板的上下变形来吸收车辆动能， 钢 材用量大， 且景观效果差； 梁柱式护栏由多根平行钢管构成， 分为圆形和矩 形， 这些梁柱式护栏的碰撞等级较低。
目前， 我国的公路和桥梁上使用的防撞护栏针对所有车辆设置， 无论是 大车还是小车， 发生碰撞时均撞在同一防撞等级的这种护栏上。 但是， 防护 小车的防撞护栏需要柔性设置， 防护大车的防撞护栏需要刚性设置； 而半刚 性的防撞护栏， 对大车来说防护等级偏低、 且钢材使用量较大。
实际上， 防撞护栏作为一种重要的安全防护设施， 在拦阻失控车辆的同 时， 应具有足够的缓冲功能； 也就是说， 防撞护栏应具有足够的防撞等级， 又具有足够的缓冲功能， 以分级消减车辆动能， 当小车碰撞时， 缓冲功能发 挥作用， 让小车停下或顺利导出； 当大车碰撞时先缓冲的同时拦阻车辆使车 辆停下或导出， 不会穿越或翻越。 同时， 作为城市道路和景区公路的防撞护 栏， 应具有一定的美观效果。

进一步地， 在上述单波梁护栏板实施例和单波梁钢护栏实施例中， 可以 在每个立柱的顶端设置柱帽。
综上所述， 在本发明单波梁护栏板及单波梁钢护栏各实施例中， 单波梁 护栏板包括一体辊轧而成的 ^栏板本体， 以及轴向对称地分布在护栏板本体 的上下边缘、 且结构相同的两个聚能环； 护栏板本体的横截面呈弧形， 两个 聚能环由护栏板本体的上下边缘分别向护栏板本体的凸起方向， 向内螺旋卷 曲而成； 单波梁钢护栏基于该单波梁护栏板设置， 当护栏板子单元受到破坏 时， 对应的聚能环迅速打开， 吸收车辆动能； 当大车与单波梁钢护栏发生碰 撞时， 在竖直方向上， 先破坏位于立柱下方刚度较小的护栏板子单元， 然后 依次向上， 破坏刚度较大的护栏板子单元， 这样可以进行缓冲， 并分级消除 车辆动能， 延长了碰撞时间， 很好地保护了司乘人员； 从而可以克服现有技 术中防撞等级低、 缓冲能力弱、 且外形不美观的缺陷， 以实现防撞等级高、 缓冲能力强、 且外形美观的优点。
最后应说明的是： 以上所述仅为本发明的优选实施例而已， 并不用于限 制本发明， 尽管参照前述实施例对本发明进行了详细的说明， 对于本领域的 技术人员来说， 其依然可以对前述各实施例所记载的技术方案进行修改， 或 者对其中部分技术特征进行等同替换。 凡在本发明的精神和原则之内， 所作 的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
