Connecting structure of prefabricated bent cap and prefabricated pier and construction method of connecting structure
The invention discloses a connecting structure of a prefabricated bent cap and a prefabricated pier and a construction method of the connecting structure, and belongs to the technical field of prefabricated bridge assembly. According to the connecting structure of the prefabricated cover beam and the prefabricated pier and the construction method of the connecting structure, the prefabricated pier and the prefabricated cover beam assembled at the top end of the prefabricated pier are included, the upper end face of the prefabricated pier integrally extends upwards to be provided with a plurality of reserved steel bars, and the assembling position of the prefabricated cover beam is correspondingly provided with a plurality of reserved cavities allowing the reserved steel bars to vertically stretch into; the top end of the prefabricated pier is connected with a cement mortar leveling layer, the top end of the outer side of the prefabricated pier is provided with a side sealing mechanism, the bottom end of the outer side of the reserved steel bar is sleeved with a sealing gasket, grouting materials are poured into the reserved cavity, and the reserved cavity is of a big-end-up structure vertically penetrating through the prefabricated cover beam. The connection sealing performance between the prefabricated bent cap and the prefabricated pier can be effectively improved, the situations of grouting hollowing and uneven grouting are avoided, and the high practical value is achieved.
本发明公开了一种预制盖梁和预制桥墩的连接结构及其施工方法，属于预制桥梁装配技术领域。该种预制盖梁和预制桥墩的连接结构及其施工方法，包括预制桥墩和装配在预制墩柱顶端的预制盖梁，预制桥墩的上端面一体向上延伸设置有若干预留钢筋，预制盖梁的装配位对应设置有若干允许每一预留钢筋竖直伸入的预留空腔，预制桥墩的顶端连接有水泥砂浆找平层，预制桥墩的外侧顶端安装有侧封机构，预留钢筋的外侧底端套装有密封垫，预留空腔的内部灌注有灌浆料，预留空腔为上下贯穿预制盖梁的上大下小结构，本发明能有效提高预制盖梁和预制桥墩之间的连接密封性，避免发生灌浆空鼓和灌浆不均的情况，具有较高的实用价值。
