Inverted socket type construction method for mounting Y-shaped steel column
The invention discloses an inverted socket type construction method for mounting a Y-shaped steel column. The inverted socket type construction method is characterized in that the Y-shaped steel column is hoisted in sections, a column head of the steel column is synchronously lifted in place along with mounting of a net rack, then a middle section is hoisted, and deformation generated by the column head is adjusted through the middle section. The method comprises the core steps that a fourth Y-shaped steel column segment is installed below a net rack; synchronously lifting the Y-shaped steel column subsection IV along with the net rack; the first Y-shaped steel column segment is installed; the second Y-shaped steel column subsection is installed; and mounting the Y-shaped steel column section III. The method has the characteristics that 1, the hoisting operation space is large, and the mounting efficiency is high; correction is convenient, and installation precision is high; 3, the hoisting safety risk is low, and the influence on the roof steel truss is small; the segmented components are light in weight and convenient to transport and hoist, and operation management of the truck crane on the floor is facilitated.
本发明公开了一种Y型钢柱安装的倒序承插式施工方法，它是一种将Y型钢柱分段吊装，其中钢柱柱头随网架安装同步提升就位，然后吊装中间分段，利用中间分段对柱头产生的变形进行调节的施工方法。核心步骤为：将Y型钢柱分段四安装在网架下方；将Y型钢柱分段四随网架同步提升；安装Y型钢柱分段一；安装Y型钢柱分段二；安装Y型钢柱分段三。该方法的特点是：1、吊装操作空间大，安装效率高；2、校正方便，安装精度高；3、吊装安全风险低，对屋面钢网架影响小；4、分段构件重量小，运输吊装方便，有利于汽车吊上楼面作业管理。
