WANG XIONG / YANG CHENG / WU HAIJUN / ZHENG HUIFEN

The invention discloses an assembling method of a pipe truss, wherein an assembling jig frame is used for assembling; the assembling jig frame comprises two supporting rods; the two supporting rods are horizontally arranged and are parallel to each other; a plurality of supporting frames are respectively arranged on the two supporting rods; all of the supporting frames on each supporting rod are uniformly distributed in the length direction of the supporting rods; connecting rods are respectively arranged at the two ends of the two supporting rods; and the same ends of the two supporting rods are respectively connected with the same connecting rod, and the two supporting rods can move on the two connecting rods. The assembling method comprises the following assembling steps of firstly adjusting the distance between two supporting rods according to the diameter of an upper chord rod, the diameter of a lower chord rod and the distance between the upper chord rod and the lower chord rod of the pipe truss to be assembled, then respectively hanging and placing the upper chord rod and the lower chord rod onto the supporting frames, and then assembling web rods between the upper chord rod and the lower chord rod; and completing the assembly of the pipe truss after the web rods are assembled. The assembling method has the advantages that the operation is convenient, the labor intensity of operators is favorably reduced, and the assembling efficiency is improved.

本发明公开了一种管桁架的装配方法，使用装配胎架进行装配，装配胎架包括两根支撑杆，两根支撑杆水平设置且相互平行，两根支撑杆上分别设有若干支撑架，每根支撑杆上的所有支撑架沿支撑杆长度方向均匀分布；两根支撑杆两端分别设有连接杆，两根支撑杆的同一端分别与同一根连接杆连接且两根支撑杆可在两根连接杆上移动；其装配步骤如下：先根据待装配管桁架上弦杆直径、下弦杆直径以及上下弦杆之间的间距调节两根支撑杆之间的间距，然后将上弦杆和下弦杆分别吊装放置在支撑架上，再在上下弦杆之间装配腹杆，待腹杆装配完成即完成所述管桁架的装配。该装配方法操作方便、利于降低操作人员的劳动强度和提高装配效率。
