Positioning method for welding type lower chord for erecting main truss
The invention discloses a positioning method of a welding type lower chord for erecting a main truss, and relates to the technical field of main truss facilities. The method comprises the following steps: according to the design line type of the main truss, presetting a first positioning part and a second positioning part at two ends of a top plate of a lower chord with a box-shaped structure, andpresetting a first supporting part and a second supporting part at two ends of a bottom plate of the lower chord; rotationally connecting the first positioning part on a to-be-erected lower chord with the second positioning part on the erected lower chord through a pin shaft; rotating the to-be-erected lower chord around the pin shaft, and adjusting the spatial position of the end, close to the erected lower chord, of the to-be-erected lower chord; and placing a pedestal with a corresponding thickness in a filling gap between the first supporting part on the to-be-erected lower chord and thesecond supporting part on the erected lower chord, and bolting the pedestal and the first supporting part and the second supporting part on the two sides of a pedestal. When the main truss is erected,the spatial position of the to-be-erected lower chord can be quickly positioned to the design position, the to-be-erected lower chord member is stably connected to the erected lower chord, and the line type meeting the design requirement is ensured.
本申请公开一种架设主桁的焊接式下弦杆的定位方法，涉及主桁架设施工技术领域，包括：根据主桁的设计线型，在箱型构造的下弦杆的顶板两端预设第一定位部、第二定位部，在下弦杆的底板两端预设第一支撑部、第二支撑部；将待架下弦杆上的第一定位部与已架下弦杆上的第二定位部通过销轴转动连接；绕销轴转动待架下弦杆，并调整该待架下弦杆靠近已架下弦杆的一端的空间位置；在待架下弦杆上的第一支撑部与已架下弦杆上的第二支撑部之间的填充间隙放置对应厚度的垫座，并栓接该垫座及其两侧的第一支撑部、第二支撑部。本申请能够在架设主桁时快速定位待架下弦杆的空间位置至设计位置，并稳定连接该待架下弦杆于已架下弦杆上，确保满足设计要求的线型。
