Road surface obstacle protection guardrail
The invention discloses a road surface obstacle protection guardrail which comprises a support and a guardrail body, the guardrail body is arranged on the support, the support comprises one or more first stand columns, each first stand column comprises a first section and a second section, and the width of at least part of the cross section of each first section is smaller than that of the cross section of the corresponding second section; the guardrail comprises a first cross beam and a second cross beam, the first cross beam is arranged on the first section, and the second cross beam is arranged on the second section. The stand column is arranged into multiple sections, the widths of the sections are different, and the bending strength of the stand column is gradually reduced from the ground to the top in a segmented mode. The single stand column is high in strength, the steel consumption is greatly reduced, and the strength of the stand column and guardrail beam installation are both considered. When the device is close to an obstacle protection position during installation, the distance between the stand columns does not need to be increased for avoiding.
本发明公开一种路面障碍物防护护栏，包括支架和护栏，所述护栏设置在所述支架上，所述支架包括一个以上的第一立柱，所述第一立柱包括第一段和第二段，所述第一段至少部分横截面的宽度小于所述第二段横截面的宽度，所述护栏包括第一横梁和第二横梁，所述第一横梁设置在所述第一段上，所述第二横梁设置在所述第二段上。通过将立柱设置成多段，各段截面的宽度不同，立柱抗弯强度从地面往上分段递减。单根立柱强度高且钢材用量大幅减少，兼顾立柱本身强度及护栏横梁安装。安装时靠近障碍物防护位置时，立柱间距不用做加大避位处理。
