Urban road isolation guardrail for resisting explosion and collision
According to the anti-explosion and anti-collision urban road isolation guardrail, a bottom plate is laid on the ground, at least two bases arranged at intervals are fixed to the bottom plate, grooves are formed in the tops of the bases, a stand column set comprises two stand columns, the bottoms of the two stand columns are jointly fixed in the grooves, the two stand columns jointly extend upwards, and a top cover is arranged at the tops of the two stand columns; the two ends of the upper and lower cross beam rods are connected with the stand columns on the inner sides of the two stand column sets respectively, the multiple angle steel connecting blocks are connected with the stand columns and the upper and lower cross beam rods, the multiple vertical rods are connected between the upper and lower cross beam rods between the adjacent stand column sets, and energy absorbed by the urban road isolation guardrail accounts for 45.5% or above of total collision energy. The energy absorption ratio is high, and the maximum offset is small.
一种用于抗爆防撞的城市道路隔离护栏，城市道路隔离护栏中，底板铺设于地面，至少两个间隔布置的底座固定于底板上，底座顶部设有凹槽，立柱组包括两根底部共同固定于凹槽中且共同向上延伸的立柱，顶盖设于两根立柱顶部，上下横梁杆两端分别连接两个立柱组的内侧的立柱，多个角钢连接块连接立柱与上下横梁杆，多个竖杆连接于相邻立柱组之间的上下横梁杆之间，城市道路隔离护栏吸收能量占碰撞总能量的45.5％以上。本发明吸能占比高且最大偏移量小。
