Bridge guardrail prefabricated unit and construction method
The bridge guardrail prefabricating unit comprises a stand column, an embedded part and a first nut, the lower end of the embedded part is used for being embedded into a bridge deck slab, a column foot of the stand column is provided with a mounting hole, and the upper end of the embedded part penetrates through the mounting hole so that the stand column can be connected with the upper end of the embedded part; the first nut is in threaded connection with the upper end of the embedded part and used for fixing the stand column. A guardrail mechanism and an impact part are arranged on the side wall of the stand column, at least one part of the guardrail mechanism is connected with the impact part, and the guardrail mechanism is located on the outer side of the impact part; a cavity used for buffering is formed in the stand column, and the impact part is used for bearing the impact force of the guardrail mechanism so that the cavity can deform. The cavity and the anti-collision part play a role in protecting the automobile under single-time fixed-direction collision, the phenomenon that hard collides with hard does not occur, reverse acting force is prevented from being generated after the automobile collides with the guardrail mechanism, and therefore deformation of the automobile is reduced, and impact damage to an accident automobile and passengers is reduced.
本发明公开一种桥梁护栏预制单元及施工方法，其中，包括立柱、预埋件和第一螺母，预埋件的下端用于预埋至桥面板内，立柱的柱脚设有安装孔，安装孔用于供预埋件的上端穿过，以使立柱与预埋件的上端连接，第一螺母与预埋件的上端螺纹连接，第一螺母用于固定立柱；立柱的侧壁设有护栏机构和撞击部，护栏机构至少一部分与撞击部连接，且护栏机构位于撞击部的外侧；立柱内设有用于缓冲的空腔，撞击部用于承受护栏机构的冲击力，以使所述空腔产生形变；此空腔和防撞部起到单次固定方向撞击下保护汽车的作用，不至于出现硬碰硬的现象，避免使汽车撞击护栏机构后产生反向作用力，从而降低车辆自身变形，减小对事故车辆和乘员的冲击伤害。
