Novel pre-pressing assembly type prestressed concrete energy dissipation and vibration reduction micro-vibration prevention base platform
According to the novel pre-pressing assembly type prestressed concrete energy dissipation and vibration reduction micro-vibration prevention abutment, transportation and construction of the abutment can be facilitated, and meanwhile the abutment has better fatigue resistance, durability, vibration reduction performance and the like. The micro-vibration prevention base table comprises a base table plate and a base table column, the base table plate is prefabricated and then transported to a construction site to be assembled with the base table column, plate preformed holes are formed in the prefabricated base table plate and penetrate through the base table plate from one side, where the base table column is installed, of the base table plate to the other opposite side of the base table plate, and column preformed holes corresponding to part of the plate preformed holes are formed in the base table column; during assembly, the base table plate is arranged on the supporting part of the base table column, the base table column and the base table plate are connected through post-tensioned prestressed tendons located in the plate preformed holes and the column preformed holes, the post-tensioned prestressed tendons are tensioned in the plate preformed holes not corresponding to the column preformed holes, hole channel grouting is conducted on the column preformed holes and the plate preformed holes after the post-tensioned prestressed tendons are tensioned, and the base table column and the base table plate are assembled. And the grouting material is an energy dissipation material.
本发明提供了一种预压装配式预应力混凝土消能减振新型防微振基台，其不仅能够便于基台的运输、施工，同时基台具有更好的抗疲劳、耐久以及减振等性能。防微振基台包括基台板和基台柱，基台板预制后运至施工地与基台柱进行组装，预制的基台板上设有板预留孔，板预留孔由基台板上安装基台柱的一侧贯穿至其相对另一侧，基台柱上设有与部分板预留孔相对应的柱预留孔；组装时，将基台板置于基台柱的支撑部上，基台柱与基台板通过位于板预留孔、柱预留孔内的后张预应力筋连接，未与柱预留孔对应的板预留孔内张拉有后张预应力筋，柱预留孔和板预留孔在张拉完后张预应力筋后进行孔道灌浆，灌浆材料为消能材料。
