Continuous bridge expansion joint structure
A continuous bridge expansion joint structure comprises concrete structure bodies, a pavement layer, a sliding isolation plate, a supporting plate, a stiffening plate, movable supports, lower base plates and an expansion joint. The lower base plates are arranged in concrete anchoring areas of the concrete structure bodies on the two sides of the expansion joint respectively and connected with thestiffening plate on the upper portion through the movable supports, the stiffening plate is fixedly connected with the supporting plates on the stiffening plate, and the sliding isolation plate is insliding connection with the supporting plate below the sliding isolation plate and is fixedly connected with the pavement layer on the sliding isolation plate. Due to the movable supports, the expansion joint structure can adapt to relative displacement of beams on the two sides, and meanwhile due to the sliding isolation plate, the influence of movement of the expansion joint structure on the pavement layer can be avoided. The continuous bridge expansion joint structure is simple in structure, high in deformation adaptability, continuous, seamless, good in driving comfort and convenient to maintain and replace.
一种连续型桥梁伸缩缝结构，包括混凝土结构体、铺装层、滑动隔离板、支撑板、加劲板、动支座、下垫板和伸缩缝。下垫板分别设于伸缩缝两侧的混凝土结构体的混凝土锚固区，通过动支座与上部的加劲板连接，加劲板与上部的支撑板固定连接，滑动隔离板与下部的支撑板滑动连接，与上部的铺装层固定连接。动支座的存在能够使伸缩缝结构适应两侧梁体的相对位移，同时滑动隔离板的存在能够避免伸缩缝结构的移动对铺装层的影响。本发明结构简单，适应变形能力强，连续无缝，行车舒适性好，维修更换方便。
