Bridge floor continuous structure of inverted-T-shaped bent cap simply supported girder bridge and seamless construction method
The invention relates to a bridge deck continuous structure of an inverted-T-shaped bent cap simply supported girder bridge and a seamless construction method. The bridge deck continuous structure comprises top truss steel bars, hinge connecting steel plates, 8-shaped steel pipes, side connecting steel plates, hinge bolts, connecting steel bars and constructional steel bars. The main beams are arranged on the two sides of the inverted-T-shaped bent cap. The 8-shaped steel pipes comprise 8-shaped steel pipes on the two sides and a 8-shaped steel pipe in the middle. The device has the beneficial effects that the steel pipe shaped like the Arabic number eight can be prefabricated in a factory, the device can be installed only by connecting the bolts and the steel bars on site, and for an old bridge, the device can be installed only by dismantling an original device and then mechanically connecting a new device; by means of the structure that the side faces are hinged and the top face is connected through the hinges, transverse connection of the 8-shaped steel pipes can have tiny dislocation, and when the main beam is subjected to the bending moment effect, due to the force transmission effect of the connecting steel bars, pulling force indirectly acts on the 8-shaped steel pipes on the two sides through the connecting steel bars.
本发明涉及一种倒T形盖梁简支梁桥的桥面连续构造和无缝化施工方法，包括：顶面桁架钢筋、合页连接钢板、∞字型钢管、侧面连接钢板、铰接螺栓、连接钢筋和构造钢筋；主梁设于倒T型盖梁两侧；∞字型钢管包括两侧∞字型钢管和中间∞字型钢管。本发明的有益效果是：∞字型钢管可以在工厂内预制，在现场仅进行螺栓与钢筋的连接，即可完成装置的安装，对于旧桥也只需要对原装置进行拆除，再进行新装置的机械连接即可完成；利用了侧面铰接与顶面合页连接的构造，使∞字型钢管的横向连接可以有微小的错动，在主梁受到弯矩作用时，由于连接钢筋的传力作用，拉力通过连接钢筋间接作用于两侧∞字型钢管上。
