Middle supporting structure of medial strip bridge guardrail
The invention relates to a medial strip bridge guardrail middle supporting structure, and relates to the technical field of bridge guardrails, the medial strip bridge guardrail middle supporting structure comprises two rows of protective columns which are fixedly arranged in the middle of a bridge at intervals, each row of protective columns is fixedly provided with a plurality of breast boards, and every two protective columns which are oppositely arranged are fixedly connected through two pull rods which are arranged in a crossed mode; two buffering cables are arranged between the two rows of protection columns and connected through a plurality of blocking cables, a net-shaped structure can be formed between the buffering cables and the blocking cables, two first buffering units are arranged on each set of pull rods, the buffering cables are wound in the first buffering units, the first buffering units can release the buffering cables with resistance, and therefore the buffering cables can be prevented from falling off. The buffer cable is connected with each group of pull rods through a second buffer unit, and after the buffer cables in the first buffer unit are all released, the buffer cables are fixedly connected with the pull rods through the second buffer units. The anti-collision guardrail has the effects that a vehicle after the breast board is broken can be buffered and blocked, and the collision energy absorption effect of the guardrail is improved.
本申请涉及一种中央分隔带桥梁护栏中间支撑结构，其涉及桥梁护栏技术领域，其包括固定设置在桥梁中间的两排间隔设置的防护柱，每排防护柱上均固定设有若干栏板，相对设置的两个防护柱之间通过两个交叉设置的拉杆固定连接；两排防护柱之间设有两条缓冲索，两条缓冲索之间通过多根拦索连接，缓冲索与拦索之间能够形成网状结构，每组拉杆上均设有两个第一缓冲单元，缓冲索收卷在第一缓冲单元内，第一缓冲单元能够有阻力的释放缓冲索，缓冲索与每组拉杆之间均通过第二缓冲单元连接，当第一缓冲单元内的缓冲索全部释放后，缓冲索通过第二缓冲单元与拉杆固定连接。本申请具有能够对栏板断裂后的车辆进行缓冲阻拦，提高护栏吸收碰撞能量的效果。
