Round pipe truss group construction method
The invention relates to the field of steel structure construction methods, in particular to a circular pipe truss group construction method which can reduce the number of times of erecting a jig frame, improve the utilization rate of the jig frame and the construction efficiency and reduce the manufacturing cost when a pipe truss is assembled, and comprises the following steps: a, ground sample paying-off: setting reference coordinates on a terrace according to processing drawing data to obtain ground sample paying-off; b, a jig frame is erected, adjusted and inspected; c, marking the center line of the pipe fitting: cutting the round pipe needing to be assembled, and marking a horizontal center line and a vertical center line on the surface of the round pipe; d, arranging the round tube on a tire and positioning: adjusting on the tire according to the data of the ground sample so that the tire is aligned with the ground sample in a paying-off manner and is fixed; and then hoisting the internal intersecting pipe from one side to a tire, paying off the internal intersecting pipe and the ground sample, respectively butting the upper chord round pipe and the lower chord round pipe, and then putting the rest chord pipes on the tire and aligning the rest chord pipes with the internal intersecting pipe. And e, carrying out linear verification and welding. The method is particularly suitable for construction of the circular pipe truss.
本发明涉及钢结构施工方法领域，尤其是一种管桁架在装配时，减少胎架搭设次数，提高胎架利用率和施工效率，减少制造成本的圆管桁架组施工方法，包括如下步骤：a、地样放线：根据加工图数据，在地坪上设定基准坐标，得到地样放线；b、胎架搭设、调整及检验；c、管件中线标注：需组拼的圆管完成切割，并在圆管表面标注水平中心线和垂直中心线；d、圆管上胎及定位：根据地样数据在胎上进行调整使其与地样放线对齐并固定；然后将内部相贯管从一侧开始吊装上胎，并将内部相贯管与地样放线、上弦圆管和下弦圆管分别对接，随后将剩余弦管上胎并与内部相贯管对齐。e、线性校验及焊接。本发明尤其适用于圆管桁架的施工之中。
