Construction method for simply supported-to-continuous structure of bridge
The invention relates to a construction method of a bridge simply-supported-to-continuous structure. The construction method comprises the following steps that S1, a lower structure is constructed; s2, a permanent support is arranged; s3, erecting a precast beam body; s4, precast beam bodies are connected; s5, hogging moment tensioning is conducted; and S6, bridge deck pavement. The padstone and the support are arranged at the top of the cover beam to serve as permanent supports, the precast beam body is supported through the padstone and the support when erected, the precast beam body is directly supported through the padstone and the support after being connected into the continuous beam, a temporary support is not needed, construction steps are reduced, construction difficulty is lowered, the support is horizontally placed to guarantee balanced stress of the support, and construction efficiency is improved. The possibility that the support deforms and the beam body laterally slides due to uneven stress is avoided, the bridge floor transverse slope is controlled through the cover beam, the bridge floor longitudinal slope is controlled through the wedge-shaped block integrally prefabricated with the prefabricated beam body, and therefore the bridge floor transverse slope and the bridge floor longitudinal slope are arranged.
本发明涉及一种桥梁简支变连续结构的施工方法，包括以下步骤：S1、下部结构施工；S2、永久支座设置；S3、预制梁体架设；S4、预制梁体连接；S5、负弯矩张拉；S6、桥面铺装。本发明在盖梁的顶部设置垫石与支座作为永久支座，架设预制梁体时通过垫石与支座来支撑，并且预制梁体连接为连续梁后直接通过垫石与支座来支撑，无需采用临时支座，减少施工步骤，降低施工难度，支座水平放置以确保支座受力均衡，避免因受力不均而导致支座变形及梁体发生侧向滑移的可能，通过盖梁来控制桥面横坡，通过与预制梁体一体预制的楔形块来控制桥面纵坡，从而实现桥面横纵坡的设置。
