The specific embodiment
embodiment 1
Slip list Pin and many truss structures 3, moulding bed 2, it comprises track 1, moulding bed 2, truss 3, pulling mechanism 4, and track 1 is provided with moulding bed 2, takes dress truss 3 on moulding bed 2, and on track 1, opposite side is also provided with pulling mechanism 4, and pulling mechanism 4 connects moulding bed 2 by wire rope.
General assembling track 1, moulding bed 2, truss 3 pass through following steps:
The first step: track 1 is laid: in consolidation shed ground basis, treat orientation and the size of slippage main couple 3, pre-designed slippage circuit, and utilize apparatus measures unwrapping wire on base plate to indicate.According to related request spacing, on base plate, accomplish fluently chemical anchor bolts, i-beam track is laid in crab-bolt plate top, track 1 adopts billet leveling, both sides horizontal slide rail axis is answered keeping parallelism, misalignment of axe is not more than 4mm, and the whole discrepancy in elevation is not more than 5mm, and amount of deflection is not more than 2mm, and with plate firm welding, between i-beam track, welded H section steel is firm across a certain distance mutually.
Second step: moulding bed setting: square box moulding bed 2 on the i-beam track laying in advance, this moulding bed 2 is double does assembled and slippage.And padded in advance tetrafluoroethene plate with i-beam track 1 contact node district below horizontal box moulding bed 2.
The 3rd step: truss lower edge is assembled, correction: utilize QUY260 crawler crane truss 3 lower chord members to be winched to above the moulding bed 2 laying in advance outside the venue, before QUY260 crawler crane pine hook, truss 3 members are proofreaied and correct and put in place, and oblique support is set in both sides in time after loose hook fixes, guarantee that truss 3 members are reliable and stable on moulding bed 1.
The 4th step: the large component assembly of lower edge and welding: after lower-chord panel point lifting puts in place, then lift another large-scale lower chord member, and weld after assembled correction.And in truss 3 both sides, front and back, support system is set and guarantees truss 3 stability and safety.
The 5th step: the assembled correction of middle web member: after truss 3 lower edge rod members are all installed and welded, start the middle web member of lifting and welding, when assembled web member, reliable support must be set, especially diagonal web member, guarantee that Stability Analysis of Structures is reliable on the one hand, another aspect guarantees that its diagonal web member is not out of shape because amount of deflection is excessive.
The 6th step: the assembled correction of winding up: truss 3 web members carry out the installation of corresponding moulding bed 2 after all installing and having welded in time, and in centre, be symmetrical arranged four vertical casing moulding bed bracing frame systems, reliable and stable during the component assembly of guaranteeing to wind up welding.
The 7th step: wind up and install and welding: chord member on assembled residue truss 3 on moulding bed 2, install after firm welding, must the reliable diagonal brace of multiple tracks be set in truss 3 both sides and fix, guarantee that truss does not topple.
The 8th step: truss welding and slippage: single Pin main couple 3 welds and detects a flaw after acceptance(check) above ground moulding bed 2, in the middle of being about to, four vertical casing moulding bed bracing frame systems are removed, before removing, reliable oblique ribs is set above both sides box moulding bed 2, and before and after truss 3 glide directions, both sides arrange reliable pulling device, while guaranteeing truss 3 slippage, stablize and do not topple.
Article two, on track 1, relevant position arranges assembly pulley and traction cucurbit, and track 1 end face is polished smooth, surface roughness reaches 1.6, and spread butter, sufficient lubrication, two arranged outside postive stop baffles below box moulding bed, the upper tetrafluoroethene plate of pad in baffle plate, track 1 welding in two of inner sides arranges two cover side direction pulleys.Guarantee truss 3 smooth slippage and safety.Before truss 3 slippages, towing point is set, each, two tracks, adopt Lever Blocks or hoist engine to draw, and are equipped with four door guide roller groups, and hauling speed should not be greater than 0.3m/min; During slippage, the asynchronous value in two ends should not be greater than 30mm.
embodiment 2
The setting of the present embodiment explanation slippage place setting and sliding rail 1.
1, slippage place arranges
This engineering B truss is taked A near axis list Pin main couple 3 assembled completing, and single truss structure 3 horizontal slidings, to the upright projection region of specified design installation position, amount to two truss structures 3 between slippage B axle and A ~ B axle.
The main assembled place of moulding bed 2 and slippage place are positioned between (2/7 axle ~ 1/8 axle)/A ~ B axle, in this region and part north and south expanded scope, must will in place, clean out, and remove the obstructions such as relevant civil engineering, guarantee that levelling of the land totally reaches truss slippage requirement.
2, the setting of sliding rail
B truss slippage need be laid four Pin I50c GB i iron altogether, from A axis to B axis laying length, is about 20m.Slippage is symmetrical two tracks 1, and between two i iron of every track 1, spacing 1m arranges H200*150*4.5*6 shaped steel and is welded and fixed.
Sliding rail below arranges expansion bolt on civil engineering concrete floor, along orbital direction spacing 500mm, arranges, and expansion bolt buried plate top and i-beam track 1 firm welding, specification plane should be greater than 300mm*300mm.
This engineering B three Pin main couple sizes are different, integral body is distributed in echelon by B axle to A axle, track 1 must be measured setting-out before laying in advance, according to the upright projection at design and installation position, position laying, after the first truss structure 3 slippages, during slippage the 2nd Pin, must re-start measurement setting-out, according to the location of main couple 3, sliding rail 1 be finely tuned, retighten and lay firmly.Guarantee that as far as possible it is upright projection in place and that install below that truss 3 slippages put in place, reduces the work of readjusting orientation.
