Improved assembled steel structure shed tunnel
The invention provides an improved split mounting type steel structure shed tunnel. The shed tunnel is provided with vertical supporting columns arranged on the two longitudinal sides of the tunnel and a shed tunnel top. A beam on the top of the shed tunnel is provided with a long-strip-shaped energy absorption unit located on the same axis as the longitudinal beam, and the energy absorption unit comprises an elastic connecting rod, a switching rod and a buffering piece which are sequentially arranged on the same axis in the direction from the starting end to the reverse end. According to the energy absorption structure provided by the invention, the steel structure shed tunnel effectively buffers the impact load effect of the wire, the tension between the adjacent stand columns is reduced, and the damage to the steel structure shed tunnel is greatly reduced.
本发明提供了一种改进的拼装式钢结构棚洞，所述棚洞有设于隧道纵向两侧的竖直支撑柱和棚洞顶；棚洞顶的梁设有与所述纵梁位于同一轴心上的长条形吸能单元，所述吸能单元包括于所述同轴心上从启动端至反向端的方向上依次设置的弹性连接棒、转换杆和缓冲件。本发明提供的吸能结构使钢结构棚洞有效地缓冲了导线冲击载荷作用，减少了相邻立柱间的拉力，大大降低了钢结构棚洞的损坏。
