High-altitude large-span suspended support dismantling method
The invention discloses a high-altitude large-span suspended support dismantling method, and relates to the technical field of constructional engineering. Comprising the steps that a jacking pre-tensioning device is installed, a reserved hole is formed in an upper cross beam, and the jacking pre-tensioning device and a falling device are installed; a lifting rod drives the bailey beam, then a steel cushion block is cut off, the lifting jack is controlled to jack up the upper bearing beam after the steel cushion block is cut off, the limiting nut is screwed out upwards, falling is carried out through the retraction amount of the lifting jack, and after the limiting nut is stressed, the lifting jack is controlled to jack up the upper bearing beam and screw out the limiting nut upwards; tightening a fixing nut at the upper bearing beam, and repeating the operation until the bailey beam falls onto the I56 bearing beam; the formwork and the bailey beam are dismantled; the steel corbel truss is dismantled; the whole steel corbel truss falls down; rod pieces are dismantled and transferred; and removing the embedded part and the preformed hole plug. According to the method, the Bailey beam is dismounted through segmented transverse sliding hoisting, and then the steel corbel truss is integrally lowered, so that the dismounting construction is convenient and fast, and the safety is high.
本发明公开了一种高空大跨度悬空支架拆除方法,涉及建筑工程技术领域。包括顶升预拉装置安装，在上横梁布置预留孔并安装顶升预拉装置和落架装置；承重主梁的顶紧及体系转换，千斤顶顶起上垫梁进行预拉紧，拧紧上挑梁处的限位螺母，吊杆带动贝雷梁上，随后割除钢垫块，割除后控制千斤顶顶起上垫梁，向上拧出限位螺母，通过千斤顶回缩量落架，限位螺母受力后，拧紧上垫梁处的固定螺母，重复以上操作直至贝雷梁落至I56垫梁上；模板及贝雷梁拆除；钢牛腿桁架拆除；钢牛腿桁架整体下落；杆件拆除及转场；拆除预埋件及预留孔封堵。本发明采用分段横向滑移吊装拆除贝雷梁，再整体下放钢牛腿桁架的方式，使得拆除施工便捷且安全性高。
