Pier beam structure, construction support platform and construction method of pier beam structure
The invention discloses a pier beam structure, a construction support platform and a construction method of the pier beam structure, and belongs to the technical field of bridge construction. The problems that in an existing bridge prefabricating and assembling technology, the construction precision requirement is too high, water leakage is likely to happen to joints, and the integrity of a bent cap is poor are solved. The semi-prefabricated bent cap formwork comprises a semi-prefabricated bent cap formwork and at least two prefabricated pier columns, at least two bottom holes are formed in the bottom of the semi-prefabricated bent cap formwork, and each bottom hole corresponds to one prefabricated pier column; the top of each prefabricated pier column is provided with a post-pouring groove and a pier column longitudinal bar, one end of the pier column longitudinal bar penetrates through the post-pouring groove and is pre-buried in the prefabricated pier column, and the other end of the pier column longitudinal bar extends upwards; and when the semi-prefabricated cover beam formwork shell is hoisted to the top end of the prefabricated pier column, the pier column longitudinal bars penetrate through the bottom hole of the semi-prefabricated cover beam formwork shell and are inserted into the semi-prefabricated cover beam formwork shell, concrete is poured into the post-pouring grooves of the semi-prefabricated cover beam formwork shell and the prefabricated pier column, and integrated connection of the semi-prefabricated cover beam formwork shell and the prefabricated pier column is achieved. The method is mainly used for bridge construction.
一种墩梁结构、施工支架平台和墩梁结构的施工方法，属于桥梁施工技术领域。为了解决现有桥梁预制拼装技术中存在施工精度要求过高、接缝处易发生漏水、盖梁整体性不佳的问题。本发明包括半预制盖梁模壳和至少两根预制墩柱，半预制盖梁模壳的底部开有至少两个底孔，每个底孔对应一根预制墩柱；每根预制墩柱的顶部开有后浇槽和设有墩柱纵筋，墩柱纵筋的一端贯穿于后浇槽并预埋至预制墩柱内，墩柱纵筋的另一端向上延伸；当半预制盖梁模壳吊装至预制墩柱的顶端时，墩柱纵筋贯穿半预制盖梁模壳的底孔并插到半预制盖梁模壳内，向半预制盖梁模壳和预制墩柱的后浇槽内浇筑混凝土，实现半预制盖梁模壳与预制墩柱的一体连接。本发明主要用于桥梁的施工。
