Steel structure for uninterrupted traffic column pier bridge jacking
The invention discloses a steel structure for uninterrupted traffic column pier bridge jacking, which comprises a column pier, a steel hoop and a beam body, wherein a high-strength anchor bolt is connected between the steel hoop and the column pier, a chemical embedded steel bar glue layer is arranged on the outer surface of the high-strength anchor bolt, a steel gasket is fixedly connected between the high-strength anchor bolt and the steel hoop, and a grouting layer is arranged between the steel hoop and the column pier. Through the effects of the steel hoops, the steel corbels, the high-strength anchor bolts, the grouting layers, the chemical embedded steel bar glue layers and the steel gaskets, the problems that a column-type pier adopted by an existing bridge is high in height, once a support is damaged, the beam needs to be jacked up for support replacement, a reinforced concrete box beam is large in weight and is more than five hundred tons, the area of a column top is generally small, a jack is unable to be placed, if a large support is arranged on the ground, the height of the support is very high, the overturning danger exists, the construction period is long, and the occupied space is large can be solved.
本发明公开了一种不中断交通柱墩桥梁顶升用的钢结构，包括柱墩和钢抱箍以及梁体，所述钢抱箍与柱墩之间连接有高强锚栓，所述高强锚栓的外表面设置有化学植筋胶层，所述高强锚栓与钢抱箍之间固定连接有钢垫片，所述钢抱箍与柱墩之间设置有注浆层。本发明通过钢抱箍、钢牛腿、高强锚栓、注浆层、化学植筋胶层和钢垫片的作用，解决了目前桥梁采用柱型墩，高度很高，一旦支座损坏，需要将梁顶起进行支座更换，钢筋混凝土箱梁重量很大，重量都在五百吨以上，柱顶面积一般很小，无法安放千斤顶，如果从地面大支架上来，支架高度很高，有倾覆危险，且施工周期长，占用场地大的问题。
