Replaceable external steel shear key of segmental prefabricated assembled pier and construction method
The invention provides a replaceable external steel shear key of a segmental prefabricated assembled pier and a construction method. The replaceable external steel shear key comprises an embedded steel plate, an embedded sleeve, an anchor bar, a rubber plate and a shear-resistant steel plate. When the prefabricated hollow pier sections are manufactured in a factory, the pre-buried steel plates andthe pre-buried sleeves are pre-buried on the inner surfaces of the section hollow pier walls on the two sides of a splicing seam and fixed through the anchor bars, and after the prefabricated hollowpier sections are spliced on site, the rubber plates, the shear-resistant steel plates and the shear-resistant rib plates are installed, bolts are screwed, and in-vitro steel shear keys are installed.It is guaranteed that dislocation, slippage and the like do not occur between the prefabricated segments, and the shear resistance effect between the segments is achieved. The external steel shear key is easy to manufacture, and the force transmission path is clear and reliable; no concrete shear key is arranged in the wall body of the hollow pier, so that interference with steel bars, prestressed pipelines and the like is avoided, and segment manufacturing is facilitated; the steel shear keys are high in shear capacity and particularly suitable for high-earthquake areas; requirements can bemet by arranging a few shear keys, and on-site installation is fast.
本发明提供一种节段预制拼装式桥墩可更换体外钢质剪力键及施工方法，可更换体外钢质剪力键包括预埋钢板、预埋套筒、锚筋、橡胶板和抗剪钢板。预制空心墩节段在工厂内制造时，将预埋钢板及预埋套筒预埋在拼接缝两侧的节段空心墩壁内表面，并通过锚筋固定，现场预制空心墩节段拼接完成后，安装橡胶板、抗剪钢板及抗剪肋板，施拧螺栓，安装完成体外钢制剪力键，保证预制节段间不发生错动、滑移等，起到节段间抗剪作用。本发明体外钢制剪力键制作简单，传力路径明确、可靠；空心墩壁体内可不设混凝土剪力键，避免与钢筋、预应力管道等干扰，方便节段制造；钢制剪力键抗剪能力强，特别适用于高震区；设置少数剪力键即可满足要求，现场安装快捷。
