Description
Technical field
The utility model belongs to technical field of building construction, and in particular to a kind of steel box girder assembling positioning device.
Background technology
It is well known that when steel structure bridge lifts, it is necessary in advance by steel box-girder to be installed and mounted steel box-girder essence
Really contraposition, after exactitude position can by weld the two is connected it is integral.To ensure welding quality, steel to be installed when welding
Both it box beam and has installed and not may occur in which relative displacement between steel box-girder, i.e., end face needs to be aligned, and cannot misplace；The two exists
Short transverse needs concordantly, to misplace, it is therefore necessary to positioning device be arranged between them.Currently, common fixed
Position device be after exactitude position, steel box-girder to be installed and installed between steel box-girder by weld horse plate, height difference positioning plate and
Jack is positioned.As shown in Figure 1, utilizing interval by after the first steel box-girder 1 and the contraposition of the second steel box-girder 2 in the prior art
Horse plate 3, the height difference positioning plate 4 of laying are positioned, wherein specifically localization method is：When the end face of the second steel box-girder 2 not with
When the end face alignment of the first steel box-girder 1 of installation, the telescopic end of jack is withstood into the side that horse plate 3 is located at the second steel box-girder 2
On, the second steel box-girder 2 is pushed using the active force of jack, makes end face and mounted first steel box-girder 1 of the second steel box-girder 2
End face alignment；When either flush of the top surface of the second steel box-girder 2 not with mounted first steel box-girder 1, for example, the second steel
The top surface of box beam 2 is less than the top surface of mounted first steel box-girder 1, jack is placed on the top surface of the first steel box-girder 1, profit
The second steel box-girder 2 is raised with the active force of jack, makes top surface and mounted first steel box-girder 1 of the second steel box-girder 2
Either flush.
Positioning is carried out using current existing horse plate 3, height difference positioning plate 4 and jack to have the drawback that：1. due to horse
Plate 3 and height difference positioning plate 4 are laid along the abutment joint interval of the first steel box-girder 1 and the second steel box-girder 2, and 1 He of the first steel box-girder
The length of second steel box-girder 2 is longer, causes the quantity of horse plate 3 and height difference positioning plate 4 more, increases construction cost；2. horse plate 3
It is welded on the first steel box-girder 1 and the second steel box-girder 2 with height difference positioning plate 4, and completes the first steel box-girder 1 and the second steel box-girder
It needs to remove horse plate 3 and height difference positioning plate 4 after 2 docking, cause in this way on the first steel box-girder 1 and the second steel box-girder 2
More leg is left, leg can reduce the intensity of the first steel box-girder 1 and the second steel box-girder 2, and leg is in prolonged rainwater
Under washing away, further decrease the intensity and service life of the first steel box-girder 1 and the second steel box-girder 2, meanwhile, remove quantity compared with
When more horse plates 3 and height difference positioning plate 4, waste time；3. using jack in positioning, the active force that jack generates is difficult
Control, it is larger or smaller to be easy to cause active force, location difficulty, reduces location efficiency.

End is provided with the first pressing plate 10, and the bottom end of second adjusting screw rod 9 is provided with the second pressing plate 11, the first pressing plate 10 and the first steel
The contact area of box beam 1 is bigger than the contact area of the first adjusting screw rod 8 and the first steel box-girder 1, similarly, the second pressing plate 11 and second
The contact area of steel box-girder 2 is bigger than the contact area of the second adjusting screw rod 9 and the second steel box-girder 2, larger using contact area
When first pressing plate 10 and the second pressing plate 11 can be such that the first adjusting screw rod 8 and the second adjusting screw rod 9 adjusts, not only reduces and act on
Pressure on first steel box-girder 1 and the second steel box-girder 2 avoids causing extrusion damage to the first steel box-girder 1 and the second steel box-girder 2,
It will can also quickly push 1 and second steel box-girder 2 of corresponding first steel box-girder.
In the present embodiment, the horse plate 3 and the height difference positioning unit are equidistantly laid.
The use process of the utility model：
The lifting of second steel box-girder 2 is just aligned to progress behind the abutment joint position of the first steel box-girder 1, completes the first steel case
After the first contraposition of beam 1 and the second steel box-girder 2, horse plate 3 and height difference positioning unit interval are laid in the first steel box-girder 1 and
At the abutment joint of two steel box-girders 2；When the end face of the first steel box-girder 1 and the second steel box-girder 2 is unjustified, horse is withstood using jack
Plate 3 makes the second steel box-girder 2 or the first steel box-girder 1 move, finally makes the end face pair of the first steel box-girder 1 and the second steel box-girder 2
Together；When the top surface of the second steel box-girder 2 is higher than the top surface of the first steel box-girder 1, the second adjusting screw rod 9 is rotated, the second steel box-girder 2 is made
It moves downward, and then makes the either flush of the top surface and the first steel box-girder 1 of the second steel box-girder 2；When the top surface of the first steel box-girder 1 is high
When the top surface of the second steel box-girder 2, the first adjusting screw rod 8 is rotated, so that the first steel box-girder 1 is moved downward, and then make the first steel case
The either flush of the top surface of beam 1 and the second steel box-girder 2.
The above is only the preferred embodiment of the utility model, not imposed any restrictions to the utility model, every
Any simple modification, change and equivalent structure made by above example are changed according to the utility model technical spirit, still
