Construction method of large-span steel beam roof suspended ceiling conversion layer
The invention discloses a construction method of a large-span steel beam roof suspended ceiling conversion layer. The construction method comprises the following construction steps that S1, the length of a vertical rod of a steel structure conversion layer is determined according to the set elevation of a steel structure roof steel beam and the elevation of a decorative suspended ceiling; s2, reserving a pipeline space; s3, connecting plates are arranged on the lower sides of flange plates of the steel structure roof main steel beams and connected with the steel beams through surrounding welding; s4, vertical rods are arranged, and inclined rods are arranged between the vertical rods for fixed connection; s5, a grid steel frame structure is fixedly arranged at the bottom of the vertical rod; s6, the two ends of the supporting beams in the horizontal direction of the main steel beams are fixed to the structural beams through supporting plates; and S7, fixing plates are welded to an upper flange plate and a lower flange plate of the steel structure roof main steel beam, diagonal draw bars are arranged, one ends of the diagonal draw bars are welded to the grid steel frame structure, the other ends of the diagonal draw bars are welded to the fixing plates, and after welding is completed, welding slag is removed, and antirust paint is brushed. The problems that a conventional suspended ceiling conversion layer construction method is poor in stability, low in safety and large in limitation are solved.
本发明公开了一种大跨度钢梁屋面吊顶转换层的施工方法，包括以下施工步骤：S1:根据钢结构屋面钢梁的设置标高和装饰吊顶标高确定钢结构转换层立杆的长度；S2:预留管道空间；S3:在钢结构屋面主钢梁的翼缘板下侧设置连接板，且与钢梁通过围焊进行连接；S4:设置立杆和立杆间设置斜杆进行固定连接；S5:在立杆的底部固定设置网格钢架结构；S6:与主钢梁水平方向的支撑梁两端通过支撑板与结构梁进行固定；S7:在钢结构屋面主钢梁的上下翼缘板焊接固定板，并设置斜拉杆，斜拉杆的一端与网格钢架结构焊接、另一端与固定板焊接，焊接完成后，焊渣清理，涂刷防锈漆。解决常规吊顶转换层施工方法出现的稳定差，安全性低，局限性大的问题。
