B, one cover jacking conditioning equipment 8 respectively is set in the both sides, top of middle steel member 9 at 2 liang of side directions of wide slideway.
C, between upper steel member 7 that has installed and middle steel member 9, lay some slide rail bearings 3; Guarantee that the line of centres of all slide rail bearings 3 and the line of centres of two middle steel members 9 are on the same vertical plane; On some slide rail bearings 3, lay wide slideway 2; The line of centres of the center line of wide slideway 2 and all slide rail bearings 3 is on the same vertical plane, and steel member 9 upper end installed surfaces in the middle of wide slideway 2 upper surfaces are higher than form one and regulate displacement nargin.
D, be coated with one deck lubricating grease 4 at wide slideway 2 upper surfaces.
Step 4, examination slippage; Check all connecting portion firm and reliable connection, loosen the lifting cable wire of tower crane 10 gradually, the whole slippage pulling equipments 5 of hand control slowly move prepackage steel member 7 ' with vertical support equipment 6 to installation direction; Stop afterwards; Check that whole slippage pulling equipments 5 are reliable with vertical support equipment 6 working stabilities, inspection lifting cable wire connects reliable, and hands over inspection qualified.
Step 5, mobile and installation prepackage steel member 7 '; All speed, slow moving are pre-installed steel member 7 ' to the whole slippage pulling equipments 5 of hand control to installation direction with vertical support equipment 6; When prepackage steel member 7 ' moves to middle steel member 9 tops; Two jack stand prepackage steel members 7 ' by two cover jacking conditioning equipments 8; Regulate prepackage steel member 7 ' in place fully through jacking conditioning equipment 8, will pre-install steel member 7 ' through connection and welding procedure at last and be installed on the middle steel member 9, accomplish installation work.
Step 6, on the prepackage steel member 7 ' that installs, do following work: the hook of taking tower crane 10; Extract whole slippage pulling equipments 5 and vertical support equipment 6; Remove top link, traction link and anti-skew card 1, remove wide slideway 2, ring rail bearing 3 and jacking conditioning equipment 8 in addition and move to another station.
The length of wide slideway 2 should be greater than sliding path length 300mm.Steel member 9 upper end installed surfaces in the middle of wide slideway 2 upper surfaces are higher than, the adjusting displacement nargin of formation is 100mm.
The present invention's embodiment more specifically is described in further detail below:
In the slippage operation: the loose hook time that note controlling tower crane.If one of full-time commander, the loose hook of commander's tower crane, each bottle gouard moved by hands keep pine consistent with the amount of drawing respectively by two people Song Hela, if deviation is arranged at any time by commander's unification adjustment.
Slide rail bearing 3 is made: the H section steel manufacture that adopts 600mm * 600mm * 25mm.Per two slide rail bearing 3 arrangement pitchs are 500mm.The height of every one slide rail bearing 3 is slide rail bearing 3 height+wide track 2 height=installation site absolute altitude+100mm.
Lubricating grease 4 can be selected lubricated butter for use, and track upper surface will be smeared evenly, must not holiday.
At top, bottom 500mm place and wide slideway 2 equidirectional layout quadruplet slippage pulling equipments 5 of hang prepackage steel member 7 ', pulling equipment is made up of the wire rope of traction draw ring, 5t bottle gouard moved by hands, diameter 18.The traction draw ring is that Ф 16 specifications are processed for the HPB235 reinforcing bar.Traction draw ring center is identical with wide slideway 2 centers.The welding of traction draw ring is received on the shaft side according to the 5d double welding.The center is consistent with prepackage steel member 7 ' steel column center, allows journal offset error ± 2mm.The loose power of pulling force He latter two slippage pulling equipment through preceding two slippage pulling equipments guarantees that steel member 7 at the uniform velocity advances along planned orbit all the time.
At four top draw rings of prepackage steel member 7 ' welded top, the top draw ring is that Ф 20 specifications are the reinforcement fabrication of HPB235.Each top draw ring is installed a vertical support equipment 6, and vertical support equipment 6 connects earth anchor, and vertical support equipment 6 is made up of the wire rope of a 15t bottle gouard moved by hands and diameter 18.Pulling force through preceding two earth anchors is guaranteed to pre-install steel member 7 ' with the loose power of latter two earth anchor and is in plumbness all the time.
Tower crane participates in cooperating co-operation, and in the whole slipping, tower crane lifting cable wire should slowly loosen, and forbids to break off relations, and plays safety rope and prevents accident.
During the examination slippage, all wire rope tensions are while send rope, tight rope, the slow slack rope of tower crane, examination slippage 300mm～500mm.Begin formal slippage after confirming to stablize, as deviation occurs, should in time adjust wire rope.
After prepackage steel member 7 ' moves to assigned address; Jack by two 10t of jacking conditioning equipment 10 will be pre-installed steel member 7 ' steady jack-up 50mm, remove sliding rail, and will be then that member is in place fully; Connect, weld, accomplish the installation work of a prepackage steel member 7 '.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
