Temporary connecting structure of prefabricated spliced bridge and prefabricated beam sections
The embodiment of the invention provides a temporary connecting structure of a prefabricated spliced bridge and prefabricated beam sections. The temporary connecting structure of the prefabricated spliced bridge comprises the multiple prefabricated beam sections which are sequentially arranged in the length direction of the bridge; embedded pipes with the center lines being arc lines are arranged in the prefabricated beam sections. The outer ends of the embedded pipes extend to the end face, extending in the width direction, in the prefabricated beam sections, and hand holes are formed in the side walls, parallel to the length direction of the bridge, in the prefabricated beam sections and communicate with the inner ends of the embedded pipes. The outer ends of the embedded pipes on the two adjacent prefabricated beam sections are correspondingly butted; an annular groove rivet with the center line being an arc line is arranged between the hand holes of every two adjacent prefabricated beam sections and the embedded pipe in a penetrating mode, the head of each annular groove rivet is located in the hand hole of one prefabricated beam section, and the tail of each annular groove rivet is located in the hand hole of the other prefabricated beam section and detachably connected with a corresponding lantern ring. According to the technical scheme provided by the embodiment of the invention, temporary pre-tightening force can be applied to the two prefabricated beam sections.
本申请实施例提供一种预制拼接桥梁的临时连接结构及预制梁段，其中，预制拼接桥梁的临时连接结构包括：多节预制梁段，沿桥梁长度方向依次布置；预制梁段内设有中心线为弧线的预埋管；预埋管的外端延伸至预制梁段中沿宽度方向延伸的端面，预制梁段中与桥梁长度方向平行的侧壁设有手孔，手孔与预埋管的内端连通；相邻两个预制梁段上的预埋管外端对应对接；相邻两个预制梁段的手孔及预埋管之间穿设有中心线为弧线的环槽铆钉，环槽铆钉的头部位于其中一个预制梁段的手孔内，环槽铆钉的尾部位于另一个预制梁段的手孔内且与套环可拆卸连接。本申请实施例提供的技术方案能够对两个预制梁段施加临时的预紧力。
