Anti-seismic energy-dissipation shallow-buried slot-type abutment connecting device
The invention discloses an anti-seismic energy-dissipation shallow-buried slot-type abutment connecting device used for assembling connection of a prefabricated hollow pier column and a bearing platform. The connecting device comprises an outer wrapping steel pipe and an embedded steel pipe. The outer wrapping steel pipe is arranged at the bottom of the prefabricated hollow pier column in a sleeving mode, and pier column longitudinal ribs of the prefabricated hollow pier column protrude and stretch out of the bottom of the outer wrapping steel pipe; and the embedded steel pipe is arranged in apier column mounting groove pre-formed in the upper side surface of the bearing platform, wherein the upper end surface of the embedded steel pipe is directly opposite to and abuts against the lowerend surface of the outer wrapping steel pipe and is welded and fixed to the lower end surface of the outer wrapping steel pipe, and concrete fills a continuous pore cavity defined by the outer wrapping steel pipe and the embedded steel pipe. The anti-seismic energy-dissipation shallow-buried slot-type abutment connecting device provided by the invention is simple and compact in structure and highin operability, the construction efficiency is improved, and the connecting device is more stable and better in seismic resistance and energy dissipation capability.
本发明公开了一种抗震耗能浅埋插槽式墩台连接装置，用于预制空心墩柱与承台的装配连接，该连接装置包括：外包钢管和预埋钢管，所述外包钢管套设在所述预制空心墩柱的底部，且该预制空心墩柱的墩柱纵筋凸伸出所述外包钢管的底部；所述预埋钢管布置在所述承台上侧面预设的墩柱安装槽内；其中，所述预埋钢管的上端面与所述外包钢管的下端面对正抵靠并焊接固定，且在外包钢管与预埋钢管围合成的连续孔腔内浇筑有混凝土。本发明提供的一种抗震耗能浅埋插槽式墩台连接装置，具有装置结构简单紧凑，可操作性强，提高了施工效率，连接装置更加稳固，具有更好的抗震耗能能力。
