Highway bridge expansion joint device capable of keeping traffic after earthquake
The invention relates to a highway bridge expansion joint device capable of keeping traffic after an earthquake, and belongs to the technical field of bridge expansion joint devices. The expansion joint device comprises a supporting system, a corrugated beam system and an anchoring system, and a corrugated beam is mainly used for replacing a plurality of profile steel longitudinal beams in a conventional large-displacement mode expansion joint device. The corrugated beam is formed by bending a steel plate for multiple times and is a whole, the corrugated beam cannot topple and slip similar to a profile steel longitudinal beam in an earthquake, rapid repair after the earthquake is facilitated, and it is guaranteed that a road is rapidly unblocked. The corrugated beam is convenient to manufacture and install, and after the corrugated beam is covered with a rubber cover plate or the top of the groove in the corrugated beam is filled with an elastic body, a waterproof system comprising a sealing rubber strip in a common scale type expansion joint device can be omitted. The anchoring concrete adopts high-toughness concrete doped with steel fibers, and the steel fibers close to the expansion joint are subjected to directional treatment, so that the anchoring concrete is not easy to damage and can be effectively bonded with the two sides of the corrugated beam.
本发明涉及一种震后保通的公路桥梁伸缩缝装置，属于桥梁的伸缩缝装置技术领域。该伸缩缝装置包括支撑体系、波折梁体系和锚固体系，主要是用一个波折梁代替了常规大位移模式伸缩缝装置中的多根型钢纵梁。波折梁为钢板经过多次弯折形成的，自身为一个整体，在地震中不会发生类似型钢纵梁的倾倒和滑落，且方便震后快速修复，保证道路快速畅通。波折梁制作和安装方便，上方覆盖橡胶盖板，或者在波折梁上凹槽的顶部填充弹性体后，可省去常规模数式伸缩缝装置中包含密封胶条的防水体系。锚固混凝土采用掺有钢纤维的高韧性混凝土，且对靠近伸缩缝的钢纤维进行定向化处理，可保证锚固混凝土不易破损且和波折梁两侧有效粘结。
