Embodiment
[0025] Such as Figure 1~3 As shown, the sliding hoisting method of a large-span pipe truss structure includes the following steps:
[0026] (1) Divide the steel structure into several units according to the number of trusses and grids, and each unit shall not be less than two trusses or two grids;
[0027] (2) The weight of each unit is divided into several sections;
[0028] (3) The track for walking tower crane and tire frame sliding is set along the vertical direction of the truss; the track is fixed on the ground axis of the steel structure design position, and the lower wing plate of the track is pressed with a pressure plate, and on the original anchor bolts The nut is tightened and fixed, and the track is welded and fixed on the embedded iron plate and the pressure plate at the same time, and the track connection is rigidly connected.
[0029] (4) According to the division of the units, the tire frame can be built and disassembled, and the tire frame is connected as ...

The invention discloses a sliding lifting method of a large-span pipe truss structure. The method comprises the following steps that firstly, the steel structure is divided into multiple units according to the number of trusses and the number of grids; secondly, the weights of the units are divided into multiple segments; thirdly, rails allowing a walking type tower crane and a bed-jig to slide are arranged in the truss perpendicular direction; fourthly, the buildable and detachable bed-jig is manufactured according to unit division, and the bed-jig is moved to the design position of a truss unit through drawing; fifthly, the walking type tower crane walks to the position nearby an assembly unit, needed segments are lifted to the sliding bed-jig in succession, after the segments are spliced and assembled into units, a sliding bet-jig support is dismounted, and the assembly unit is directly placed on the design support position; and sixthly, the walking type tower crane walks to the pull point of the position nearby the assembly unit to achieve drawing to achieve equal elevation sliding, the support is fixed, splicing is carried out unit by unit in this way, and segmented sliding isachieved till construction of the whole steel structure is completed. The large-span pipe truss system is directly arranged at the design position in place, and precision can be guaranteed easily.
Description
technical field [0001] The invention belongs to the technical field of hoisting, in particular to a sliding hoisting method for a large-span pipe truss structure. Background technique [0002] With the progress of society, the large-span space structure is booming, the span is getting bigger and bigger, the shape is getting more and more novel and unique, and the technical requirements for installation and construction are getting higher and higher. In the actual construction, there are projects with relatively large span, weight and installation height. The ground cannot bear the impact force generated by the crane when hoisting, and the conventional method cannot be used for installation. Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned prior art, and provides a sliding hoisting method for a large-span pipe truss structure. [0004] The present invention solves the above-mentioned technical problems through th...
