Continuous structure of simply supported girder bridge deck
The invention relates to the technical field of bridge engineering design and construction, and provides a simply supported beam bridge deck continuous structure which is laid in a notch between a first prefabricated main beam and a second prefabricated main beam and comprises a positioning part, a supporting steel plate, a flexible part and an ultra-high performance concrete pavement layer. A first rib plate is arranged on the upper surface of the positioning part located above the first prefabricated main beam, and a second rib plate is arranged on the upper surface of the positioning part located above the second prefabricated main beam; one side of the supporting steel plate is welded with the first rib plate, and the other side is welded with the second rib plate; the flexible part is fixed to the face, facing the positioning part, of the supporting steel plate and is in sliding fit with the positioning part. And the ultra-high performance concrete pavement layer is paved above the supporting steel plate. According to the bridge deck continuous structure of the simply supported girder bridge, the problems of concrete cracking and deformation of the bridge deck continuous structure of the simply supported girder bridge under the effects of vehicle load, temperature load, concrete shrinkage and creep and the like can be effectively solved.
本发明涉及桥梁工程设计与施工技术领域，提供一种简支梁桥桥面连续构造，其铺设于第一预制主梁和第二预制主梁之间的槽口内，简支梁桥桥面连续构造包括定位部件、支撑钢板、柔性件和超高性能混凝土铺装层，位于第一预制主梁上方的定位部件的上表面设有第一肋板，位于第二预制主梁上方的定位部件的上表面设有第二肋板；支撑钢板一侧与第一肋板焊接，另一侧与第二肋板焊接；柔性件固定于支撑钢板朝向定位部件的一面，并与定位部件滑动配合；超高性能混凝土铺装层铺设于支撑钢板的上方。本发明提供的简支梁桥桥面连续构造，可以有效抵抗简支梁桥桥面连续构造在车辆荷载作用、温度荷载、混凝土收缩徐变等作用下的混凝土开裂以及变形问题。
