The utility model discloses a new rail bridge, including bridge and guardrail guardrail, the outer surface of the upper and lower ends are respectively provided with an upper and lower through holes, a beam installed inside the through holes on the front end of the baffle block is installed on the outer wall of the right. The beam end is provided with a clamping groove, a wrought iron fence is installed between the upper beam and lower beam. The new bridge guardrail, through the guardrail column, beam and block with the foot nut fixed on the upper surface of the bridge body, unscrew the nut can quickly replace the guardrail, internal through hole inserted on the upper beam, the elastic effect of compression spring makes the block is inserted into the card slot, stuck on the beam, pull ring drive rod to move backwards, pull rod drives the block from the card slot, the beam can be removed, with the card slot and block the installation and disassembly of the upper beam is very convenient, if the replacement of damaged beams was quickly, to prevent the occurrence of the bridge accident.

一种新型桥梁护栏
本技术涉及桥梁工程
,具体为一种新型桥梁护栏。
技术介绍
桥梁护栏广泛用于桥边,但现有技术的护栏一般仅限于对行人的防护,目前桥梁护栏是栅栏式,由于结构的原因,机械强度不够,不能满足特别是对车辆的防护要求,容易出现安全隐患,由于车辆运行时惯性大,单纯的刚性护栏大部分是单一的支撑杆,防护效果,容易被车辆撞坏,从桥面上掉下去,造成很大的死伤,在现有技术中,如申请号为201620230350.1的技术专利,包括混凝土墩、底板、底座、立柱及横杆,所述底板的底部设有若干定位柱,所述底板浇注固定在混凝土墩上,所述底板的上表面与混凝土墩的上表面齐平,所述底板的上表面设有若干螺栓孔,所述底座上设有与螺栓孔相对应的通孔,所述底座通过螺栓拧紧固定在底板上,所述立柱固定在底座上,所述立柱顶端设偶若干通孔,所述横杆包括金属板,所述金属板的截面呈形,所述金属板的背面设有若干螺杆,所述螺杆穿过立柱顶部的通孔并用螺母拧紧固定,所述金属板的外表面包覆有缓冲层,该技术的桥梁护栏虽然坚固且有缓冲效果,但是如果被撞坏,更换和维修都需要很长时间,容易造成坠桥事故。
