Description
Technical field
The present invention relates to a kind of grand bridges to build the high buttress Hanging Basket in construction, especially a kind of bottom basket of high buttress Hanging Basket
Downward putting device and method.
Background technique
The BR-06 grand bridge of Teheran the north highway first stage of the project project is entire project the most key position.Bridge
Location is located at the northern 9 degree of earthquake territories in Teheran.It is pre- across Wavelike steel webplate using 3 to bridge superstructure in order to mitigate bridge self weight
Prestressed concrete continuous beam.Span of bridge is arranged as 83+153+83=319m.Left and right width spacing distance 2m.The bridge main span 1# pier
Pier shaft left panel height 28m, right panel height 31m；On the hillside of the mulberry side koris TEHRAN.2# pier pier shaft or so width pier shaft is high
65.5m, the bridge main span 153m at the foot of the hill built up positioned at the mulberry koris opposite side SHRINE is across mulberry koris and winding public affairs
Road.Bridge 2 pier is set to show especially magnificent in the mountain valley of overhanging cliff.The box beam 0 of BR-06 grand bridge#The a height of 8.8m in block center, conjunction
Hold together section (17# block) high 3.5m.Deck-molding section is by 1.8 parabola variations.Steel web Construction of Continuous Box Beam using Hanging Basket gradually to
Be pushed forward into technique.The 0 of the dividing strip of box beam or so width is arranged in its tower crane#At block.Cradle construction to the segment box beam 10# position
It sets；Because of tower crane brachium 50m.Tower crane can not vertical direct hoisting heavy.Box beam closure segment is apart from tower crane center away from being
76.5m.There is 73m in its top surface from road surface.There is 84m apart from mulberry koris bottom.Closure segment construction, which finishes, to need to remove Hanging Basket.It hangs
The top diamond shape frame of basket can fall back at the tower crane radius of gyration and remove, but bottom basket can not just be returned.
The bottom basket planar dimension of Hanging Basket are as follows: along bridge to 6.6m, direction across bridge 10m.
Every component always weighs about 24 tons.
Transferring bottom baskets with 25 tons of hoist engine " walking 3 " wirerope in 10m or so for height is not to be a problem；It can also use
Loop wheel machine parks on the ground each section component dismounting to bottom basket.But for height 70m or more, loop wheel machine can not be torn open in this position
It removes.The rope capacity that there is hoist engine using hoist engine decline bottom basket is inadequate, can not also transfer.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention proposes bottom basket downward putting device and the side of a kind of high buttress Hanging Basket in mountain area
Method.
The technical scheme is that a kind of bottom basket downward putting device of the high buttress Hanging Basket in mountain area, including gear jack, essence

Deng.
Gear jack 1 is placed in box beam, and the fining twisted steel 2 by passing through box beam wing plate connects the bottom basket of Hanging Basket,
For declining the bottom basket 1.7m of Hanging Basket；The bottom basket top of Hanging Basket after decline is equipped with gusset plate 3, and gusset plate 3 is connected by screw-thread steel
Connect device 6 and fine-rolling screw nut 4 and the fixed company of the fining twisted steel 2 being connected between hydraulic punching jack 11 and the bottom basket of Hanging Basket
It connects, punching jack 11 is placed in box beam by stringer 18 and crossbeam 17.It is placed vertically with shoulder pole girder two of cradle construction and makees stringer
18.Two 18 spacing 290mm of stringer, center setting backing plate I14 and fine-rolling screw nut II16.Fine-rolling screw nut II16 is fixed's
Fining twisted steel 2 prevents its downslide.A crossbeam 17 is set up on two stringers 18.Backing plate II15 is disposed on crossbeam 17.
Backing plate II15 is having a size of 500 × 400 × 30mm.It opens centreHole.The direction 500mm and the crossbeam side 640mm of backing plate II15
To identical.Cylinder jack 11 is set on backing plate II15.
Such as Fig. 4, shown in 5,6, it is symmetrically welded and connected bar 10 between the stringer of the bottom basket of gusset plate 3 and Hanging Basket, on gusset plate 3
Fine-rolling screw nut 4 by chain block 5 connect Hanging Basket bottom basket stringer and front beam, wherein 5 one end of chain block passes through steel
Cord II8 connection fine-rolling screw nut 4, the other end pass through wirerope I7 longitudinal beam connected and front beam.
As shown in figure 13, fining twisted steel is formed by connecting by the screw-thread steel that more root long degree are 12m, is led between two screw-thread steels
It crosses screw-thread steel connector to be fixedly connected, and pinions end with iron wire on screw-thread steel connector, for preventing stripped thread.
Fining twisted steel is unless cause specific.General cut lengths 12m.More than 70 m of decentralization just need to connect.In order to reliable
Both ends are linked to be entirety.It is first separated by the length equity of screw-thread steel connector 6, is made at 2 both ends of fining twisted steel and want precession long
Degree goes out mark.Guarantee 6 producing balanced forces of screw-thread steel connector in this way.To prevent midway stripped thread.It is used at 6 both ends of screw-thread steel connector
16# iron wire 19 pinions end (see Figure 13).
Now the construction procedure the decline of bottom basket is described below:
1) in construction to closing up previous piece (16 of block#Block) position；(depending on box beam span) is in advance at box beam center
Top plate and bottom plate settingHole.Its distance, which is subject to, supports the front and rear beam center of bottom basket away from 5.8m, sees Fig. 1.
2) closure segment construction finishes, and the components such as top template, skid beam in closure segment box beam are removed in advance.
3) with the bottom basket 1.7m of 32t gear jack decline Hanging Basket.See Fig. 2,3.
4) it is first penetrated down from the hole that top surface of the beam is arranged with the fining twisted steel of 4.5m long, when reaching bottom plate, according to
The secondary fine-rolling screw nut for screwing on fining twisted steel puts on gusset plate, then after screwing on screw-thread steel connector, the bottom end of fining twisted steel
It is inserted into the front beam of bottom basket.Then upper padding plate III is covered in the bottom of front beam, screws on fine-rolling screw nut and fixes.
To prevent from shaking during decline.Bar is symmetrically welded and connected between gusset plate and stringer.After welding, hand is used
Draw cucurbit one end by wirerope I connection fine-rolling screw nut, one end passes through wirerope II longitudinal beam connected and front beam.(i.e. steel wire
Rope sling on crossbeam after be pressed on stringer) as the 2nd insurance.Form it into a frame entirety.See Fig. 6 (bottom basket thin portion) with
4 suspender belts in Fig. 2 are removed afterwards, are converted to Fig. 7,8 stress system.
5) in the device of box beam top surface position of opening arrangement decline.With shoulder pole girder (the long 640mm, height of cradle construction
240mm, width 214mm) two place vertically and make stringer.Two stringer spacing 290mm, center setting backing plate I and fine-rolling screw nut II.Finish rolling
Nut II is fixedFining twisted steel prevent its downslide.A crossbeam is set up on two stringers.Pacify on crossbeam
Set backing plate II.Backing plate II is having a size of 500 × 400 × 30mm.It opens centreHole.The direction 500mm of backing plate II and crossbeam
The direction 640mm is identical.The YCW100B type jack that OVM is produced is set on backing plate II.See Fig. 9,10.
Punching jack main technical detail are as follows: stretching force 973.1KN, oil pressure 51MPa, punching apertureTensioning
Stroke 200mm, size
Punching jack working principle:
As shown in Figure 10, it opens oil pump → oil inlet pipe fuel feeding → hydraulic punching jack jacks → and withstands backing plate I → finish rolling
Nut I → fine-rolling screw nut II clamps fining twisted steel and rises → rises 180mm；Therebetween the fine-rolling screw nut II between two stringers also with
Rise 180mm → oil pump fuel cut-off → the fine-rolling screw nut II between following stringer and screw off on backing plate I → hydraulic punching
Jack oil return → the whereabouts backing plate I → fine-rolling screw nut II is screwed at backing plate I, and passes make the steady decline of bottom basket gradually,
(see Figure 11,12).
