Embodiment Construction

[0015] The overall lifting method of the ultra-long, light and thin giant steel pipe truss of the present invention comprises the following steps in sequence:

[0016] a) First, on the floor, set control lines along the C-axis offset by 15m to both sides, as the assembly control axis along the X direction, and set 6 Y-direction control lines along the direction perpendicular to the C-axis to form an assembly control axis network ;

[0017] b) Then install the temporary tire frame, the assembled tire frame is welded together with the steel plate pre-embedded on the concrete beam, and fixed firmly;

[0018] c) Then set up the support guide frame. One set of support frame uses two 1.28x1.28m lattice standard sections with a height of 21m. There are 5 sets in total. One set of guide frame uses two 1.28x1.28m lattice standard sections. The height is about 2m higher than the lifting height, a total of 4 groups, and the foundation is just connected to the concrete root;

Abstract

The invention discloses an integral lifting method for an ultra-long light thin giant steel tube truss. The method sequentially includes the following steps: a) setting control lines on a floor in a manner of respectively shifting to two sides along an axis C by 15cm, setting six Y-direction control lines along the direction perpendicular to the axis C, and forming an assembly control axis network; b) mounting a temporary scaffold, welding the scaffold together with steel plates embedded on concrete beams, and fixing firmly; c) arranging supporting guide frameworks, and enabling feet to be in rigid connection with concrete roots; d) assembling and aligning all lower chords on the scaffold, and increasing restraining plates, used for positioning connectors, for the chord connectors sectionally and sequentially after integral adjustment; e) lifting, selecting an upper-chord horizontal main tube of the truss as a lifting top anchor, lifting tooling beams through a transfer structure, and fixing a hydraulic jack; f) unloading; g) measuring deflection, setting stress and strain measuring points, and performing stress and strain monitoring on bars at typical positions of the truss.

Description

technical field [0001] The invention relates to a construction method, in particular to an overall lifting method for an ultra-long, light and thin giant steel pipe truss. Background technique [0002] At present, the domestic railway construction is in the golden stage. A large number of high-standard and long-span modern railway station buildings such as Beijing South Railway Station, Xiamen West Railway Station, Nanjing South Railway Station, Wuhan Station, and Guangzhou Station stand out. The commonality of these large railway station buildings is The point is: the construction period is relatively short, and there are many cross operations. The roofs of the station houses are all made of steel structure roofs with relatively large spans, requiring a new overall lifting method of steel pipe trusses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overall lifting method for an ultra-long, light and thin gi...
