Fragmented prefabricated assembled bridge and construction method thereof
The invention discloses a fragmented prefabricated assembled bridge and a construction method thereof.The fragmented prefabricated assembled bridge comprises a supporting mechanism and a prefabricated main beam, the supporting mechanism comprises a supporting column and a prefabricated cover beam, the prefabricated cover beam is arranged at the top of the supporting column, and the prefabricated cover beam comprises two prefabricated beam pieces arranged in the bridge direction; each precast beam piece comprises a precast concrete block, shear key teeth and embedded forward connecting ribs, the shear key teeth are arranged on the precast concrete block and protrude out of the inner wall face of the precast concrete block, and the embedded forward connecting ribs are arranged on the precast concrete block and protrude out of the inner wall face of the precast concrete block; an opening groove which is arranged in the transverse bridge direction and provided with an opening in the top is formed in the middle of the capping beam initial blank, and high-performance concrete is poured into the opening groove to form a beam piece wet joint so that the two prefabricated beam pieces can be connected to form a whole beam structure body. The fragmented prefabricated assembled bridge is easy to construct, and continuity and integrity of the prefabricated bent cap are kept.
本发明公开了一种分片预制拼装桥梁及其施工方法，包括包括支撑机构和预制主梁，支撑机构包括支撑柱和预制盖梁，预制盖梁设于支撑柱的顶部，预制盖梁包括沿顺桥向设置的两片预制梁片，预制梁片包括预制混凝土块、剪力键齿和预埋顺向连接筋，剪力键齿设于预制混凝土块上且凸出于预制混凝土块的内壁面设置，预埋顺向连接筋设于预制混凝土块上且凸出于预制混凝土块的内壁面设置，盖梁初坯的中部形成有沿横桥向布设且顶部开口的开口凹槽，通过在开口凹槽内浇筑高性能混凝土形成梁片湿接缝以将两片预制梁片连接形成整梁结构体。本发明的分片预制拼装桥梁，施作简单，且保持预制盖梁的连续性和完整性。
