Construction method and device for bridge jacking steel column-embracing beam
The invention discloses a construction method and device for jacking a steel embracing column beam of a bridge. The construction method and device are used for solving the problems that in the prior art, the steel embracing column beam is not firm in installation, weak in anti-shearing capacity and low in construction efficiency. The device comprises shear keys and a steel embracing column beam, the steel embracing column beam is an annular body formed by splicing a plurality of sections end to end, the shear keys are fixedly connected with the steel embracing column beam through high-strength bolts, the shear keys are rectangular thick steel plates and are vertically installed, the ends, away from the steel embracing column beam, of the shear keys are fixed ends, and the ends, away from the steel embracing column beam, of the shear keys are fixed ends. And the fixed end is embedded and fixed in the notch of the pier column. The device is simple, convenient and rapid to use and can be recycled, and the steel column-embracing beam is prefabricated in a factory, so that the site construction period can be shortened.
本发明公开了一种桥梁顶升钢抱柱梁施工方法及装置，用于解决现有技术中钢抱柱梁安装不牢靠、抗剪切能力弱、施工效率低的问题。该装置包括剪力键和钢抱柱梁，其中，所述钢抱柱梁是由多段首尾拼接的多段组成的环状体，以及，与所述钢抱柱梁通过高强螺栓紧固连接的剪力键，该剪力键为矩形厚钢板，且竖向安装，远离钢抱柱梁的剪力键端部为固定端，该固定端埋入并固定在墩柱的槽口内。本装置使用方法简便，快捷，可循环利用，钢抱柱梁通过工厂预制，可缩短现场的施工工期。
