Bridge support cast-in-place connection construction method adapting to rigid frame beam body temperature displacement
The invention discloses a bridge support cast-in-place connection construction method adapting to rigid frame beam body temperature displacement. The method comprises the following steps: step one, a fixed bridge support and a rigid frame beam body are connected through a sliding friction pair; step two, the rigid frame beam body and the fixed type bridge support integrally fall down; step three, cast-in-place connection of the fixed bridge support and the support pad stone of the pier is constructed; step four, a displacement adjusting block is installed; step five, a wear-resisting plate is taken out; and step six, the rigid frame beam body and the fixed type bridge support are fixedly connected. A temporary sliding friction pair with a low friction coefficient is arranged between the beam body and the support, the kidney-shaped hole is formed to meet the temperature displacement amount of the beam body relative to the upper plate of the support, in the pouring process of the support and the support pad stone, the support is temporarily changed into a movable support, so that the beam body can freely stretch on the friction surface, internal force generated by the beam body is released through temperature displacement, and it is avoided that a cast-in-place material which does not reach the design strength cracks.
本发明公开了一种适应刚构梁体温度位移的桥梁支座现浇连接施工方法，包括步骤：一、利用滑动摩擦副连接固定型桥梁支座和刚构梁体；二、刚构梁体和固定型桥梁支座整体下落；三、固定型桥梁支座和桥墩的支座垫石现浇连接；四、安装位移调节块；五、取出耐磨板；六、刚构梁体和固定型桥梁支座紧固连接。本发明在梁体和支座间设置临时低摩擦系数的滑动摩擦副，设腰型孔满足梁体相对于支座上板的温度位移量，在支座与支座垫石浇筑过程中，使支座临时变成活动型支座，使梁体可以在此摩擦面上自由伸缩，温度位移使梁体产生的内力得以释放，避免现浇材料未达到设计强度的浇筑材料出现裂纹。
