Combined anti-collision guardrail system suitable for urban bridge with sidewalk
The invention discloses a combined type anti-collision guardrail system suitable for an urban bridge provided with a sidewalk. The combined type anti-collision guardrail system comprises a roadway guardrail and a sidewalk guardrail. The roadway guardrail comprises a cross rod, a stand column and a roadway guardrail base. A sidewalk guardrail base is arranged at the bottom of the sidewalk guardrail, a plurality of sleeper beams are arranged between the sidewalk guardrail base and the roadway guardrail base at intervals, and a plurality of sidewalk plates are arranged above the sleeper beams; the middle rigidity of the sidewalk slab is greater than that of two sides; the rigidity of the sidewalk guardrail base is smaller than that of the sleeper beam; a sidewalk system (sidewalk plates, sleeper beams and sidewalk guardrail bases) in an urban bridge participates in a roadway anti-collision guardrail system to form a combined anti-collision system, collision energy is shared together, the step-by-step buffering effect is achieved, on the premise of ensuring that the anti-collision safety performance is met, the structure in a traditional guardrail is optimized, and the anti-collision safety performance is improved. Therefore, the light and attractive appearance is realized, and the landscape requirements of urban bridges are better met.
本发明公开了适用于设置有人行道的城市桥梁的组合式防撞护栏系统，包括车行道护栏和人行道护栏；所述车行道护栏包括横杆、立柱和车行道护栏底座；所述人行道护栏底部设置有人行道护栏底座，人行道护栏底座与车行道护栏底座之间间隔设置多根枕梁，枕梁上方设置多块人行道板；所述人行道板中部刚度大于两侧刚度；所述人行道护栏底座的刚度小于枕梁的刚度；本发明将城市桥梁中的人行道系统（人行道板，枕梁，人行道护栏底座），参与到车行道防撞护栏体系中，形成组合式防撞系统，共同分担碰撞能量，起到逐级缓冲的效果，在确保满足防撞安全性能的前提下，优化传统护栏中的构造，使其显得轻盈美观，更好地适应城市桥梁景观性需求。
