The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is illustrated further.
Embodiments of the invention: large span light section steel structure roof girder hanging method of the present invention is applied to the lifting of 55 meters large span light section steel structure roof girders, because the length overlength of the roof girder of 55 meters spans, can process in factory, but its transport difficulty is big, also uneconomical, therefore stride roof girder to 55 meters and carry out sectional making processing, be transported to splicing lifting behind the job site.After being transported into the scene, to properly put on large span light section steel structure roof truss in order to avoid it deforms, level up the splicing place with sleeper, measure the sleeper relative elevation with level gauge, the discrepancy in elevation needs in the 5mm scope, so that described roof girder does not deform, Fig. 1 is 55 meters long-span roofing assembly unit schematic diagrames of the embodiment of the invention.Also available No. 10 channel-section steels, make in the roof girder lifting and stand up minimizing distortion in the process to increase the rigidity of roof girder web as the stiffener of roof girder web.Roof girder installs dismountable this stiffener in back, also can not remove, and Fig. 3 is that the roof girder web of the embodiment of the invention is reinforced schematic diagram, A among the figure, and B, C and D are respectively the position of reinforcement point.It more than is described first step.
Second step: select the lifting wire rope for use, according to the colligation form of roof girder and suspender weight and lifting, selecting the single maximum weighted of wire rope between described crane and suspender for use is 3.0t.Selecting specification is the wire rope of φ 21.5 for the 6*19 diameter, and its rupture pull force is 245.5KN, then its:
Lifting safety factor f=245.5 * 0.85/ (9.8 * 3.0)=7.1.
Get lifting safety factor permissible value [f]=6, then f＞[f];
Selecting the single maximum weighted of wire rope between described suspender and member for use is 5.0t.Selecting specification is the wire rope of φ 26 for the 6*19 diameter, and its rupture pull force is 362.0KN, then its:
Lifting safety factor f=362.0 * 0.85/ (9.8 * 5.0)=6.3
Get lifting safety factor permissible value [f]=6, then f＞[f].
Third step: select a crane and a suspender for use, selecting crane for use is one 50 tons of mobile cranes, long 32.75 meters of bar, and 7 meters of operating radius can lift by crane 10 tons; Because the roof girder overlength steadily, adopts a balance sling to lift for guaranteeing lifting.Described suspender is that a seamless steel pipe and a L50 angle steel by φ 219*6, φ 76*3.5 is made into triangular truss formula balancing pole suspender, long 18 meters of described suspender, and Fig. 2 is described suspender schematic diagram.When lifting,, in the lifting process, adjust balance simultaneously, 9.2 tons of roof girder and suspender deadweights in the present embodiment with chain block with 6 some liftings of triangular truss formula balancing pole suspender binding.Fig. 4 is 55 meters large span light section steel structure roof girder lifting schematic diagrames, wherein colludes into an equilateral triangle by the suspension hook top with three points at suspender two ends, and in other words, the angle of the outside steel wire of suspension hook and triangular truss formula balancing pole suspender is 60 degree.
The 4th step: carry out initially lifting, before described roof girder lifting, determine the particular location of good described crane earlier, when described roof girder lifts, should slowly lift by crane, when treating described roof girder built on stilts 200mm, stop to hoist, described roof girder of scrutiny and suspender have or not distortion, determine errorless after, lifting is to the installation site, and behind described roof girder hoisted in position, two ends high-strength bolt node adopts interim bolt earlier, lifted first, second roof girder pulled on safety net immediately, prevents that the operating personnel high-altitude from falling, tie-rod and Eurya plant bar between the roof truss are installed then, are made two roof trusses form a stabilization element.
The 5th step: carry out finally lifting: the method by first, second sheet room frame of above lifting continues all the other roof trusses of lifting, behind every lifting 5 Pin room framves, after verticality, spacing, the quality of inspection roof truss meets standard, just can make the high-strength bolt that roof truss is connected with steel column.
Large span light section steel structure roof girder hanging method of the present invention uses in the large span light section steel structure roof girder hoisting engineering of Shanghai Baosteel A Sailuo laser assembly solder engineering first phase, second phase and west, Hongqiao Airport, Shanghai freight terminal, effect is remarkable, has obtained exploiting entity, supervisor and owner's abundant affirmation.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique under the situation that does not break away from the spirit and scope of the present invention, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
