Transverse sliding construction method for circular curve steel beam
The invention provides a circular curve steel beam transverse sliding construction method which is characterized by comprising the following steps that S10, a sliding support is erected, four slide way beams are arranged at the top of the sliding support, and the arrangement direction of the slide way beams is transverse relative to a bridge; s20, a check block, a transverse pushing jack and a sliding shoe are sequentially arranged on each sliding way beam; s30, a support and a jacking jack are installed on the pier top of the pier; s40, the steel beam is hoisted to the four sliding shoes; s50, a jack is transversely pushed to push sliding shoes to drive the steel beam to move forwards to the position over the four bridge piers; and S60, the jacking jack jacks the steel beam, the sliding support is dismantled, the steel beam falls on a support at the top of the pier, the elevation of the steel beam is adjusted, and steel beam erection is completed. The circular curve steel beam transverse sliding construction method is wide in application range, suitable for construction of circular arc steel beams with different curvature radiuses and suitable for construction of S-shaped curve steel beams at the same time.
本发明提供了一种圆曲线钢梁横向滑移施工方法，其特征在于：包括以下步骤：S10：搭设滑移支架，在滑移支架顶部设置滑道梁，滑道梁数量为四条、布置方向相对桥梁而言为横向设置；S20：每一个滑道梁上顺次设置挡块、横推千斤顶及滑靴；S30：在桥墩墩顶安装支座和顶升千斤顶；S40：吊装钢梁至四个滑靴上；S50：横推千斤顶推动滑靴带动钢梁前移至四个所述桥墩正上方位置；S60：顶升千斤顶顶升所述钢梁，拆除滑移支架，钢梁落于墩顶的支座，调整钢梁标高，完成钢梁架设。本发明所述的圆曲线钢梁横向滑移施工方法适用范围广，不仅适用于不同曲率半径圆弧钢梁的施工，同时也适用于S形曲线钢梁的施工。
