Dome assembling jig frame scattered dismantling construction method
The invention discloses a scattered dismantling construction method for a dome assembly jig frame, and relates to the field of steel structure engineering building construction, and the method comprises the following steps: S1, dividing the whole jig frame into a plurality of dismantling parts; s2, dividing a dismantling process according to the dismantling part in the S1; the dismantling process comprises the steps that an operation platform on the dome jig frame is dismantled firstly, then a jig frame body is dismantled, and the step of dismantling the jig frame body comprises the steps that a string beam in the middle is dismantled firstly, and then lower triangles and a center inner cylinder at the two ends are dismantled; s3, positioning and paying off are conducted, and temporary lifting lugs are arranged on the dome; s4, scattered dismantling construction is conducted on the dome assembling jig frame according to the adjusted and divided dismantling parts and processes; the scheme is used for filling up the technical blank of dismantling a steel structure building with a large span in a limited space, namely carrying out protective dismantling on a steel structure jig frame in the limited space in the dome; therefore, the purposes of reducing dome hoisting collision risks, reducing high-altitude operation and improving operation efficiency are achieved.
本发明公开了一种穹顶拼装胎架零散拆除施工方法，涉及钢结构工程建造施工领域，包括以下步骤：S1：将整个胎架划分多个拆除部分；S2：根据S1中拆除部分划分拆除流程；所述拆除流程包括先拆除穹顶胎架上的操作平台，后拆除胎架主体，所述拆除胎架主体的步骤包括：先拆除中间的张弦梁，再拆除两端的下三角和中心内筒；S3：定位放线，在穹顶上设置临时吊耳；S4：按照调整划分后的拆除部分和流程，进行对穹顶拼装胎架的零散拆除施工；本方案用于填补受限空间内拆除跨度较大的钢结构建筑，即是穹顶内部受限空间内对其钢结构胎架进行保护性拆除的技术空白；以此达到减少穹顶吊装碰撞风险、减少高空作业、增加作业效率的目的。
