Sectional integral type prestress hoisting construction method for steel structure oblique beam by rotating method
The invention discloses a steel structure oblique beam rotation method segmented integral type prestress hoisting construction method. The method comprises the following steps that a, a first layer of steel frame is hoisted; b, laying a first layer of profiled steel sheets, and mounting a second layer of frame structure; c, hoisting outriggers at two ends of the second layer; d, two layers of profiled steel sheets are laid, and three layers of frame structures are installed; e, hoisting of all frame structures and outriggers is completed in sequence; f, checking the position relation of the outrigger; g, integrally hoisting and rotating the cant beam in place; h, the unbonded prestressed steel bars penetrate into the whole layers of frame beams; j, the prestressed tendons are tensioned and anchored from bottom to top; k, respectively welding and fixing the connecting ends of the cant beam and the cantilever beam; m, other accessory components are installed; and n, overall checking and acceptance. According to the invention, the hoisting in-place efficiency is high, the hoisting precision is higher, the connecting node strength is high, the bearing capacity of the steel structure frame can be improved, and the reliable connection between the cantilever beam and the oblique beam can be realized.
本发明公开了一种钢结构斜梁旋转法分段整体式预应力吊装施工方法，包括以下步骤：a.第一层钢框架吊装；b.第一层压型钢板铺设，二层框架结构安装；c.二层两端挑梁吊装；d.二层压型钢板铺设，三层框架结构安装；e.依次完成全部框架结构及挑梁吊装；f.校核挑梁位置关系；g.斜梁整体吊升旋转就位；h.各层框架梁整体分别穿入无粘结预应力钢筋；j.由下往上分别张拉预应力筋并锚固；k.斜梁与挑梁连接端分别施焊固定；m.其他附属构件安装；n.整体校核验收。本发明吊装就位高效，吊装精度较高，连接节点强度大，可提升钢结构框架承载能力，亦可实现挑梁与斜梁之间的可靠连接。
