Prestressed concrete beam hogging moment area bridge structure and construction method thereof
The invention discloses a prestressed concrete beam hogging moment area bridge structure and a construction method thereof, and relates to the technical field of bridge engineering. The construction method of the prestressed concrete beam hogging moment area bridge structure comprises the steps that obtaining prefabricated T-shaped beams and a prefabricated bridge deck slab; hoisting the two prefabricated T-shaped beams to enable the two prefabricated T-shaped beams to be in butt joint, and forming a groove which is positioned in a hogging moment area and is used for mounting a prefabricated bridge deck slab between wing plates of the two adjacent T-shaped beams; after two adjacent beam ribs are connected, hoisting the prefabricated bridge deck slab in the groove, after the prefabricated bridge deck slab and wing plate at one side are connected on one side, applying a prestress to the prefabricated bridge deck slab at the other side, and connecting the prefabricated bridge deck slab atthe side with the corresponding wing plate and beam rib to form a whole for common loading. The construction method is simple, convenient and rapid, the obtained bridge structure in the hogging moment area of the prestressed concrete beam is reliable in stress, and the construction method has high use value and good economic benefits in new bridge construction and old bridge transformation.
一种预应力混凝土梁负弯矩区桥梁结构及其施工方法，涉及桥梁工程技术领域。预应力混凝土梁负弯矩区桥梁结构的施工方法包括：获得预制T梁以及预制桥面板；吊装两个预制T梁使两个预制T梁对接且相邻的两个T梁的翼板之间形成位于负弯矩区的用于安装预制桥面板的凹槽，连接相邻的两个梁肋后将预制桥面板吊装于凹槽，单侧连接预制桥面板和单侧翼板后，于另一侧对预制桥面板施加预应力，然后连接该侧的预制桥面板和对应的翼板及梁肋，形成整体，共同负载。上述施工方法简便快捷，获得的预应力混凝土梁负弯矩区桥梁结构受力可靠，在新桥建设及旧桥改造具有较大的使用价值和良好的经济效益。
