Description
Technical field
It the utility model is related to building engineering field, and in particular to a kind of spacing correction branch for the control of box beam pushing tow
Frame.
Background technology
The construction of box beam method is one of construction method conventional and important in bridge construction, and its principle is to pass through jack
Apply horizontal thrust, by slideway or sliding block by piecewise or whole section of beam pushing tow forward, fall beam after in place, change formal bearing.Top
Pushing manipulation instead of hoist engine and coaster with level jack.Incremental launching method is to make on the A Geer bridges of Austria nineteen fifty-nine earliest
With being characterized in：Because Work places limit within the specific limits, can ceiling be set above operation field and makes construction not by day
Gas influences, all-weather construction.
In bridge incremental launching construction, when girder lateral deviation pushing tow route is larger, bridge need to be made using deviation correcting device
Return on predetermined pushing tow route.In theory, pushing tow design advance track is continuous, along the continuous cloth in planned course line both sides
Put stopping means pushing tow girder can be completely secured and advance along planned course, will not deviate, that is, not need deviation correcting device.
In Practical Project, due to construction error on Temporary Piers, box beam and slideway, so as to cause box beam in each slideway
Upper friction will not be definitely identical, and some engineering designs are not symmetrical structures, therefore can offset axis during pushing tow
Line position, thus for ensure box beam can accurately pushing tow to design attitude, it is necessary to correction control is carried out during pushing tow.
During actual pushing tow, generally use fixed idler whell is straight using the jack laterally set as stopping means
Pick up top and carry out dynamic correcting to girder, it is spacing with correction often it is synchronous alternately, rectifying a deviation will when returning to designed path
Be converted to it is spacing, such as deviate during spacing it is larger will enable correction, and frequently changing two kinds of equipment necessarily makes the company of pushing tow
Continuous property substantially reduces.
Utility model content
The purpose of this utility model is to provide for a kind of simple to operation integrating spacing with deviation-correcting function use
In the spacing deviation-rectifying bracket of box beam pushing tow control.
In order to solve the above technical problems, the utility model provides a kind of spacing deviation-rectifying bracket for the control of box beam pushing tow：

Shape wooden unit 2, and ensure to be filled up by bolt 2 between beam body and tetrafluoro slide plate 3, as box beam pushing tow moves ahead, constantly amendment skew,
Return on axis.
(4) when beam body pushing tow goes out spacing deviation-rectifying bracket, spacing deviation-rectifying bracket is removed, moves to the Temporary Piers of next needs
Post, repeat step (1)~(4).
Embodiment 2：
The present embodiment is improved on the basis of above-described embodiment, is theed improvement is that：If box beam is in pushing tow process
In, the beam body overall offset pushing tow axis of pushing tow box beam 12 then can be in the rear and front end peace of the same side that pushing tow box beam 12 is inclined to
Spacing deviation-rectifying bracket is filled, the spacing deviation-rectifying bracket of opposite side of pushing tow box beam 12 is same as Example 1, and is synchronously fed in the same side
Bolt 2, corrected with reaching the overall of the skew of pushing tow box beam 12.If the overall offset of pushing tow box beam 12 and front and back end offset distance
From it is different when, then frequency can be fed according to the front and back end offset distance adjustment bolt 2 of pushing tow box beam 12, make pushing tow box beam 12
In overall offset makeover process, while take into account the left and right skew of pushing tow box beam 12.
The other parts of the present embodiment are same as the previously described embodiments, therefore repeat no more.
Embodiment 3：
The utility model can be arranged on pushing tow box beam 12 all around in four orientation, and in pushing tow box beam in work progress
After 12 rear ends remove the spacing deviation-rectifying bracket of rear end, the spacing deviation-rectifying bracket of rear end is removed, moves to the correction of pushing tow box beam front end
Next interim pier stud 10 of interim pier stud 10 where support, pushing tow box beam 12 is set to be maintained at four orientation upper limit corrections.
To reach more preferable spacing and rectifying effect, its Specific construction is embodied as：

Spacing deviation-rectifying bracket is symmetrically installed by the second anchor ear 15 connected on 8 to be fixed on interim pier stud 10, and with pushing tow box beam 12
Push process be constantly put into the tetrafluoro slide plate 3 for scribbling lubricant between beam body and roller 1, complete the spacing top of pushing tow box beam
Push away.
(2) when pushing tow box beam 12 shifts, suitable bolt 2 is put on the direction that pushing tow box beam 12 is offset,
Realize the correction during box beam pushing tow.When the push route of pushing tow box beam 12 returns to axis, stopping is put into bolt
2, continue box beam pushing tow.
(3) after the rear end of pushing tow box beam 12 removes the spacing deviation-rectifying bracket of rear end, the spacing deviation-rectifying bracket of rear end is removed, is moved to
Next interim pier stud 10 of interim pier stud 10 where the deviation-rectifying bracket of pushing tow box beam front end, continues to complete the control of box beam pushing tow
Spacing and correction.
Using this embodiment, box beam pushing tow process can be limited in four orientation, reaches good limit effect, simultaneously
The installation of spacing deviation-rectifying bracket is carried out simultaneously with dismantling with box beam pushing tow process, it is not necessary to after box beam pushing tow process is stopped
The installation and dismounting of spacing deviation-rectifying bracket are carried out again, are reached continuous pushing tow process, have been saved duration and the energy.Meanwhile four
Carry out spacing in individual orientation, the offset distance of box beam is smaller, and correction process is simple to operation.
The other parts of the present embodiment are identical with above-described embodiment 1, therefore repeat no more.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other under the enlightenment of the present invention
Various forms of products, however, make any change in its shape or structure, it is every with identical or similar to the present application
Technical scheme, be within the scope of the present invention.
