Rescue evacuation facility on fabricated railway bridge and construction method
The invention provides a rescue evacuation facility on fabricated railway bridge and a construction method. The rescue evacuation facility comprises a foundation body, stand columns and stairs, connecting columns are arranged at the bottoms of the stand columns, preformed holes correspond to connecting keys in the foundation body in a one-to-one mode, the stairs are arranged at the tops of the stand columns, and preformed holes are formed in the two sides of the bottoms of the stairs; shear key top free ends are arrange in a one-to-one corresponding manner with the bottoms of the stairs; Splicing seams are formed between the upper surface of the foundation body and the bottoms of the stand columns, the upper surface of the foundation body and the bottoms of the stand columns are spliced and connected with the connecting keys through the splicing seams, splicing seams are formed between the tops of the stand columns and the bottoms of the stairs, and the tops of the stand columns and the bottoms of the stairs are spliced and connected with the shear keys through the splicing seams; and grouting materials are arranged in the preformed holes of the connecting columns provided with theconnecting keys. The stand columns in an evacuation passage are high in height and small in size, the stand columns are prefabricated in factories and hoisted and assembled on site, supports do not need to be erected, and safety is high; stairs in the evacuation channel are of a continuous structure, prefabricated stairs are adopted, hole-by-hole hoisting and erection construction are conducted,and the site construction time is obviously shortened.
本发明提供一种装配式铁路桥上救援疏散设施及施工方法，包括基础体、立柱和楼梯，立柱底部设置有连接柱，预留孔与基础体内的连接键一一对应，楼梯设置在立柱顶部且楼梯底部两侧设置有预留孔，抗剪键顶部自由端与楼梯底部的预留孔一一对应，基础体上表面与立柱底部之间设置有拼接缝且二者通过拼接缝与连接键拼装连接，立柱顶部与楼梯底部之间设置有拼接缝且二者通过拼接缝与抗剪键拼装连接，设置有连接键的连接柱的预留孔内设置有灌浆料。本发明使得疏散通道中立柱高度高、尺寸小，立柱采用工厂预制，现场吊装装配，无需搭设支架，安全性高；疏散通道中楼梯采用连续结构，采用预制楼梯，逐孔吊装、架设施工，现场施工时间明显缩短。
