Abstract
The invention discloses a transverse positioning device for an amplitude separation type steel box girder and an application method of the transverse positioning device and belongs to the field of bridge construction device. The transverse positioning device comprises a telescopic connecting girder, a hinge connector and a pushing device, wherein the telescopic connecting girder and the hinge connector are connected, and the pushing device is used for adjusting telescoping length of the telescopic connecting girder. The application method includes: fixing the positioning device in the middle of the amplitude separation type steel box girder which needs to be positioned; controlling pushing or contracting of the pushing device to push or contract the amplitude separation type steel box girder, stopping pushing or contracting of the pushing device when the position of the amplitude separation type steel box girder meets the requirement, and fixing current telescoping length of the telescopic connecting girder; when positioning and construction of the amplitude separation type steel box girder is completed, removing connection between a base and the amplitude separation type steel box girder, and removing fixation of the telescopic connecting girder. By the transverse positioning device which can be used repeatedly, accurate transverse positioning of the amplitude separation type steel box girder can be achieved simply, conveniently and fast.
Description
Technical field
The invention belongs to bridge construction device field, be applicable to the horizontal fine adjustment of framing type steel box-girder.
Background technology
Framing type steel box-girder is generally made up of left and right width two parts steel box-girder and middle connecting cross beam.After left and right two width steel box-girder lift by crane respectively, because two width steel box-girder are positioned in the air, and steel box-girder weight is large, horizontal spacing adjustment comparatively difficulty.Especially, after inclined guy cable stretching, two width steel box-girder laterally positioning are difficult to realize.Due to the laterally very difficult realization of positioning of two width steel box-girder, middle permanent connecting cross beam installs difficulty, needs connecting cross beam locally to cut off.To steel box girder construction quality and integral bridge linearly totally unfavorable.
Summary of the invention
The object of the invention is to: propose the horizontal rackwork of a kind of framing type steel box-girder and using method thereof, the aerial horizontal fine adjustment of framing type steel box-girder can be realized simply, quickly and easily, and device can be reused.
The object of the invention is realized by following technical proposals:
The horizontal rackwork of a kind of framing type steel box-girder, comprises the scalable tie-beam and articulated joint that are connected, and regulates the thrustor of described scalable tie-beam collapsing length.
As preferred embodiment, described scalable tie-beam comprises telescoping member and the supporting member of movable nested encryptions, and described thrustor is located between described telescoping member and supporting member, fixes with one, contacts with another.
As preferred embodiment, described telescoping member activity is nested in described supporting member, and described thrustor is positioning jack, and be located in described supporting member, one end and described supporting member are fixed, and the other end contacts with described telescoping member.
A using method for the horizontal rackwork of aforementioned framing type steel box-girder, comprises the following steps successively:
1) rackwork is positioned in the middle of the framing type steel box-girder needing positioning, its two ends are detachably fixed with a single width steel box-girder respectively;
2) pushing tow or the contraction of thrustor is controlled, framing type steel box-girder backed down or shrinks, when framing type steel box-girder position meets the demands, stopping pushing tow or the contraction of thrustor, and fixing scalable tie-beam collapsing length now, now framing type steel box-girder is adjusted to the right place;
3) after the positioning of framing type steel box-girder puts in place and constructed, remove the connection between itself and framing type steel box-girder, and remove fixing scalable tie-beam, now framing type steel box-girder fine adjustment has also been constructed.
Beneficial effect of the present invention: the horizontal rackwork of framing type steel box-girder of the present invention and using method thereof, the aerial horizontal fine adjustment of framing type steel box-girder can be realized simply, quickly and easily, and device can be reused, be applicable to Practical Project to use, installing for large scale steel structure high altitude also has very strong reference.
Accompanying drawing explanation
Fig. 1 is the elevational schematic view of the embodiment of the present invention;
Fig. 2 is the floor map of the embodiment of the present invention;
Wherein 1 for articulated joint, 2 be telescoping member, 3 for supporting member, 4 for positioning jack, 5 be single width steel box-girder.
Detailed description of the invention
Following non-limiting examples is for illustration of the present invention.
As shown in Figure 1, 2, the horizontal rackwork of a kind of framing type steel box-girder, comprises the scalable tie-beam that is connected and the articulated joint 1 for resisting two single width steel box-girder 5 unbalanced moments, and regulates the thrustor of scalable tie-beam collapsing length.As preferred embodiment, as shown in this embodiment, scalable tie-beam comprises telescoping member 2 and the supporting member 3 of movable nested encryptions, telescoping member 2 activity is nested in supporting member 3, thrustor is positioning jack 4, be located in supporting member 3, one end and supporting member 3 are fixed, and the other end contacts with telescoping member 2.
The using method of the horizontal rackwork of aforementioned framing type steel box-girder, comprises the following steps successively:
1) be positioned over by rackwork in the middle of the framing type steel box-girder needing positioning, detachably fixed with a single width steel box-girder 5 respectively at its two ends, namely telescoping member 2 and a single width steel box-girder 5 are detachably fixed, and articulated joint 1 and another single width steel box-girder 5 are detachably fixed;
2) pushing tow or the contraction of positioning jack 4 is controlled, framing type steel box-girder is backed down or shrinks, during positioning jack 4 pushing tow, framing type steel box-girder separates relatively, when positioning jack 4 shrinks, framing type steel box-girder bounces back naturally relatively, when framing type steel box-girder position meets the demands, stop pushing tow or the contraction of positioning jack 4, and fixing scalable tie-beam collapsing length now, by temporary fixed between telescoping member 2 and supporting member 3, now framing type steel box-girder is adjusted to the right place;
3) when the positioning of framing type steel box-girder puts in place, complete after steel box-girder welding and permanent crossbeam be in place, remove the connection between itself and framing type steel box-girder, and remove fixing scalable tie-beam, that namely removes between telescoping member 2 and supporting member 3 is temporary fixed, now framing type steel box-girder has adjusted, and now, rackwork can reuse.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
