Vertical double-stacked anchored assembly type anti-collision guardrail and mounting method thereof
The invention discloses a vertical double-stacked anchored assembly type anti-collision guardrail and a mounting method thereof. The assembly type anti-collision guardrail comprises an anti-collision guardrail, a bridge deck slab and a cast-in-place check block, wherein the anti-collision guardrail and the bridge deck slab are prefabricated by concrete; the anti-collision guardrail is provided with a pouring groove, a first embedded steel bar, an anti-collision guardrail constructional steel bar, a grouting opening, an exhaust opening, a bar guiding groove, a first hoisting ring and a second hoisting ring. 2 # embedded steel bars, 3 # embedded steel bars and stop block constructional steel bars are arranged on the bridge deck slab; after assembly, the bottom face of the anti-collision guardrail is placed on the bridge deck slab, the top ends of the second embedded steel bars stretch into the bar guiding grooves to be positioned, the second embedded steel bars and the third embedded steel bars are in lap joint with the corresponding first embedded steel bars to form a double-lap anchoring structure, and the pouring grooves and the bar guiding grooves are filled with concrete. And the stop block is cast in situ at the position of the stop block constructional steel bar on the bridge deck slab and fits and limits the lower part of the vehicle-back surface of the anti-collision guardrail. The connecting and anti-collision effects are stable, hoisting, positioning and assembling are convenient, and the mounting efficiency is high.
本发明公开了一种竖向双叠锚固的装配式防撞护栏及其安装方法，该装配式防撞护栏包括由混凝土预制的防撞护栏和桥面板以及现浇的挡块；防撞护栏上设有浇筑槽、1#预埋钢筋、防撞护栏构造钢筋、灌浆口、排气口、导筋槽、吊装环一和吊装环二；桥面板上设有2#预埋钢筋、3#预埋钢筋和挡块构造钢筋；装配后，防撞护栏底面放置在桥面板上，2#预埋钢筋顶端伸入导筋槽内定位，2#预埋钢筋和3#预埋钢筋分别与对应的1#预埋钢筋搭接形成双叠锚固结构，浇筑槽和导筋槽内填充混凝土，挡块现浇在桥面板上挡块构造钢筋所在位置且对防撞护栏背车面下部贴合限位。本发明连接、防撞效果稳固，吊装、定位、装配方便，安装效率高。
