Height-limiting protective frame with energy absorption and buffering functions
The invention belongs to the field of traffic infrastructures and particularly relates to a height-limiting protection frame with energy absorption and buffering functions. The frame is characterizedin that a cross beam transversely penetrates through and is supported on two upright posts on two sides of a road, two inclined struts are obliquely arranged on back faces of two stand columns respectively, a round pipe or a square pipe is arranged in the middle of the interior of the cross beam and arranged in the axial direction of the cross beam, a plurality of stiffening ribs are uniformly arranged along the circumference of the circular pipe or the square pipe, the round pipe or the square pipe is filled with an energy-absorbing buffer material, periphery of the cross beam is further wrapped with the energy-absorbing buffer material, the round pipe or the square pipe and stiffening ribs are made of composite materials, and a first stop block and a second stop block are arranged on theside, close to the road, of the top of the stand column along the periphery of the joint of the beam and the stand column. The height-limiting protective frame has advantages of light weight, high strength, energy absorption, buffering and simple installation, can consume energy generated by impact of an ultrahigh motor vehicle, and reduces the probability of casualties caused by collapse of thecross beam as much as possible.
本发明属于交通基础设施领域，具体涉及一种具有吸能缓冲功能的限高防护架，包括：横梁横穿支撑于道路两侧的两根立柱之上；两根斜撑分别倾斜设置在两根立柱的背车面；所述横梁内部中间为圆管或方管，所述圆管或方管沿所述横梁轴向布置；若干个加劲肋沿所述圆管或方管一周均匀布置；所述圆管或方管内部填充有吸能缓冲材料，沿所述横梁一周还外包有吸能缓冲材料；所述圆管或方管和加劲肋均采用复合材料制成；所述立柱顶部在靠近路中一侧沿所述横梁与立柱连接处一周设有第一挡块和第二挡块。本发明所述限高防护架具有轻质、高强、吸能缓冲、安装简单的优点，可消耗超高机动车撞击产生的能量，尽最大可能减小横梁倒塌致人伤亡的概率。
