5), the first supporting block 32 and dumbbell-shaped arch rib 1, supporting beam 33 are welded, complete installation positioning.
It as preferred embodiment, in step 1), is positioned on bracket 4 using total station, releases centralized positioning
Transverse axis utilizes setting-out axis tooth pad and jacking component.
As preferred embodiment, in step 2), when dumbbell-shaped arch rib 1 is placed on two pieces of limit plates in positioning element
It when between 31, is often tentatively clamped using clamping device, it is avoided to tilt be collapsed limit plate 31.
As preferred embodiment, in step 3), jacking apparatus is jack 22, is jacked using jack 22,
And the exposed length of 22 oil cylinder of jack is recorded after preliminary jacking.
As preferred embodiment, in step 4), after the adjustment for completing height tolerance, need along dumbbell-shaped arch rib 1
Length direction moves the first supporting block 32 and guarantees that the first supporting block 32 is bonded with dumbbell-shaped arch rib 1.
As preferred embodiment, in step 5), after having welded the first supporting block 32, jack 22 is moved away, first
Bracer 32 stress can support dumbbell-shaped arch rib 1 of having good positioning well.
In embodiment, a method of positioning being installed using the dumbbell-shaped arch rib 1 of the device in above-described embodiment, including
Following steps:
1), total station is fixed on bracket 4, ajusts the position of total station according to the design needs.Total station is on bracket 4
Centralized positioning transverse axis, and the positional relationship of the dumbbell-shaped arch rib 1 secured according to the preceding paragraph are released, determines positioning region substantially
The installation site of part and jacking component.Meanwhile according to the length of single hop dumbbell-shaped arch rib 1, positioning element and top are adjusted in design
The distance of ascending part part.First on bracket 4, Welder's fashioned iron at the position of the dumbbell-shaped arch rib 1 secured close to the preceding paragraph, and
Lay out the first supporting block 32.Limit plate 31 is welded in supporting beam 33, the distance of limit plate 31 is slightly larger than the width of dumbbell-shaped arch rib 1
Degree, and will shake the hand 311, threaded post 312 and follow block 313 is installed on limit plate 31.Followed by along 1 extending direction of dumbbell-shaped arch rib
Welding platform plate 23, and jack 22 is fixed on platform board 23, jack 22 is on centralized positioning transverse axis.Very heavy
The upper end for pushing up 22 oil cylinders is provided with the second supporting block 21, and 21 lower end of the second supporting block and the cylinder upper end of jack 22 are fixed, really
The first supporting block 32 and the second supporting block 21 are protected on centralized positioning transverse axis.
2), dumbbell-shaped arch rib 1 is lifted between two pieces of limit plates 31 in positioning element using crane, and is located at the
On one supporting block 32 and the second supporting block 21.The first supporting block 32 is adjusted, guarantees the height and position of its welding ends.It is appropriate to jack up
Jack 22 enables the second supporting block 21 to support the other end of dumbbell-shaped arch rib 1 well.Meanwhile it being pressed from both sides using clamping device
Tight dumbbell-shaped arch rib 1, is tentatively adjusted to vertical for dumbbell-shaped arch rib 1.
3) it, carries out tentatively jacking to designed elevation, and utilizes the vertical degree deviation and height of apparatus measures dumbbell-shaped arch rib 1
Deviation.
4), vertical degree deviation is adjusted using clamping device to unscrew one of them in same pair of clamping device and tighten
Another, the side that 1 tuning of dumbbell-shaped arch rib can be unscrewed.Clamping device is utilized simultaneously, moreover it is possible to be realized to dumb-bell shape
Arch rib 1 carries out the transfer of lateral position, facilitates ensuring that it, in centralized positioning transverse axis, reduces difficulty of construction.
Height tolerance is adjusted using jack 22, the length that 22 oil cylinder of jack is exposed after tentatively jacking is recorded, according to need
Height tolerance is wanted to be adjusted it, concrete operations are as follows:
When dumbbell-shaped arch rib 1 is lower than design value, the protruded length of 22 oil cylinder of jack is recorded.By the oil of jack 22
Cylinder jacking, makes cylinder jacking protruded length measure the sum of length of oil cylinder and height tolerance equal to last time.First supporting block 32 at this time
There are gaps with the down tube of dumbbell-shaped arch rib 1, and the first supporting block 32 is moved to far from 21 direction of the second supporting block, guarantees first
The down tube of the fitting dumbbell-shaped arch rib 1 of supporting block 32.
When dumbbell-shaped arch rib 1 is higher than design value, to close to mobile first supporting block 32 in 21 direction of the second supporting block.Due to
First supporting block has certain thickness, and moving the down tube of rear first supporting block 32 and dumbbell-shaped arch rib 1, there are gaps, avoids subsequent
Dumbbell-shaped arch rib 1 is propped up by the first supporting block 32 and is not declined with jack 22 in 22 course of exerting pressure of jack.Thousand are recorded at this time
The protruded length of 22 oil cylinders of jin top.Pressure release is carried out to jack 22, measures cylinder jacking protruded length reduced value equal to last time
Height tolerance.First supporting block 32 is moved to far from 21 direction of the second supporting block, guarantees that the first supporting block 32 is bonded dumb-bell shape
The down tube of steel pipe.
5), the first supporting block 32 and dumbbell-shaped arch rib 1, supporting beam 33 are welded, pressure release is carried out to jack 22, makes stress
Point is fallen in the first supporting block 32, thus completes installation positioning.
The welding ends of dumbbell-shaped arch rib 1 can be finally welded on the last period welded dumbbell-shaped arch rib 1, be completed
The connecting welding of dumbbell-shaped arch rib 1 works.Jack 22 and limit plate 31 are withdrawn after the completion, and wherein limit plate 31 can be by cutting
Cut completion separation.Jack 22 and limit plate 31 can continue in the location and installation work of next section of dumbbell-shaped arch rib 1.
Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also
To reach good effect.Those skilled in the art can also make equivalent change on the premise of without prejudice to spirit of the invention
Shape or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
