Prefabricated reinforced concrete side anti-collision guardrail connected with bridge, and construction method thereof
The invention discloses a prefabricated reinforced concrete side anti-collision guardrail connected with a bridge, and a construction method thereof. The prefabricated reinforced concrete side anti-collision guardrail connected with the bridge comprises a guardrail body, angle steel, a check block fixed to the bridge surface of the bridge and an embedded part embedded in the bridge, and an embedded fixing groove is formed in the lower end of the guardrail body and connected to the check block in a clamped mode; connecting steel bars are arranged on the bottom surface between the embedded groove and the head-on collision surface of the guardrail and at the lower end of the head-on collision surface of the guardrail, and the connecting steel bars are welded to the two inner side surfaces ofthe angle steel; and the embedded part comprises a steel plate and bent embedded steel bars, the embedded steel bars are fixed in a bridge, the steel plate is fixed at the upper ends of the embedded steel bars, and the lower outer side face of the angle steel is welded to the steel plate. The connection strength between the guardrail and the bridge is improved, the whole guardrail is not prone tooverturning, meanwhile, the construction efficiency is high, the use of steel is reduced, and the purpose of saving resources is achieved.
本发明公开了一种连接桥梁的装配式钢筋混凝土侧边防撞护栏及施工方法，其中连接桥梁的装配式钢筋混凝土侧边防撞护栏包括护栏、角钢、固定于桥梁的桥面上的挡块和预埋于桥梁的预埋件，所述护栏的下端设有嵌固槽，所述嵌固槽卡接于挡块；所述嵌固槽和护栏的迎撞面之间的底面及护栏的迎撞面的下端均设有连接钢筋，此连接钢筋与角钢的两个内侧面焊接；所述预埋件包括钢板和弯曲的预埋钢筋，所述预埋钢筋固定于桥梁内，所述钢板固定于预埋钢筋的上端，所述角钢的下外侧面焊接于钢板。本发明提高了护栏与桥梁之间的连接强度，整体不易倾覆，同时施工效率高，还减少钢材的使用，起到节约资源的目的。
