Bridge support pre-pressing construction structure and construction method
The invention relates to the technical field of bridge construction, in particular to a bridge support pre-pressing construction structure which comprises a concrete base. A pier column and a support used for bridge concrete cast-in-place construction are arranged on the concrete base, a hoop is installed on the pier column, and the support comprises a stand column, a cross beam and a longitudinal distribution beam. The cross beam is arranged at the top end of the stand column, the longitudinal distribution beam is arranged on the cross beam, and the longitudinal distribution beam located above the pier column is in lap joint with the upper end of the pier column. The hoop is provided with a horizontal steel plate, the horizontal steel plate is provided with a center hole jack, and the center hole jack is connected with the longitudinal distribution beam through a steel strand; and a displacement sensor is arranged on the longitudinal distribution beam. According to the structure, the longitudinal distribution beams are tensioned to pre-press the support, the construction process is simplified, the construction cost is saved, the construction period is shortened, the safety risk is reduced, and the pre-pressing force is uniform. The invention further provides a bridge support pre-pressing construction method.
本发明涉及桥梁施工技术领域，具体是一种桥梁支架预压施工结构，包括混凝土基座，所述混凝土基座上设有墩柱和用于桥梁混凝土现浇施工的支架，所述墩柱上安装有抱箍，所述支架包括立柱、横梁和纵向分配梁，所述横梁设置在立柱的顶端，所述纵向分配梁设置于横梁上，位于墩柱上方的纵向分配梁与墩柱的上端搭接；所述抱箍上设有水平钢板，所述水平钢板上安装有穿心式千斤顶，所述穿心式千斤顶通过钢绞线与纵向分配梁连接；所述纵向分配梁上设有位移传感器。本发明通过对纵向分配梁张拉，以实现对支架的预压，简化施工工艺，节省施工成本，缩短施工周期，降低安全风险，并且预压力均匀。本发明还提供了一种桥梁支架预压施工方法。
