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 case beam.
Background technology
Framing type steel case beam generally by about width of cloth two parts steel case beam and middle connecting cross beam form.About after two width of cloth steel case beams lift by crane respectively because two width of cloth steel case beams are positioned in the air, and steel case beam weight is large, the horizontal spacing adjustment is comparatively difficult.Especially behind the inclined guy cable stretching, two width of cloth steel case beams laterally positioning are difficult to realize.Because two width of cloth steel case beams laterally positioning are difficult to realize that middle permanent connecting cross beam is installed difficulty, needs the connecting cross beam part to cut off.Totally unfavorable to steel box girder construction quality and integral bridge linearity.
Summary of the invention
The object of the invention is to: propose a kind of horizontal rackwork of framing type steel case beam and using method thereof, can realize simply, quickly and easily the aerial laterally fine adjustment of framing type steel case beam, and device can be reused.
The object of the invention realizes by following technical proposals:
The horizontal rackwork of a kind of framing type steel case beam comprises the scalable tie-beam and the articulated joint that are connected, and the thrustor of regulating described scalable tie-beam collapsing length.
As optimal way, described scalable tie-beam comprises telescoping member and the supporting member of movable nested connection, and described thrustor is located between described telescoping member and the supporting member, fixes with one, contacts with another.
As optimal way, described telescoping member activity is nested in the described supporting member, and described thrustor is located in the described supporting member for the positioning jack, and an end and described supporting member are fixed, and the other end contacts with described telescoping member.
The using method of the horizontal rackwork of a kind of aforementioned framing type steel case beam may further comprise the steps successively:
1) rackwork is positioned in the middle of the framing type steel case beam that needs positioning, its two ends are detachably fixing with a single width steel case beam respectively;
2) pushing tow or the contraction of control thrustor, framing type steel case back is opened or shunk, when framing type steel case beam position meets the demands, stop pushing tow or the contraction of thrustor, and fixing scalable tie-beam collapsing length at this moment, this moment, framing type steel case beam was adjusted to the right place;
3) when framing type steel case beam positioning put in place and construct finish after, remove its with framing type steel case beam between be connected, and remove fixing to scalable tie-beam, this moment framing type steel case beam fine adjustment and construct and finish.
Beneficial effect of the present invention: the horizontal rackwork of framing type steel case beam of the present invention and using method thereof, can realize simply, quickly and easily the aerial laterally fine adjustment of framing type steel case beam, and device can be reused, be fit to Practical Project and use, installing for large scale steel structure high altitude also has very strong reference.
Description of drawings
Fig. 1 is the elevational schematic view of the embodiment of the invention;
Fig. 2 is the floor map of the embodiment of the invention;
Wherein 1 is that articulated joint, 2 is that telescoping member, 3 is that supporting member, 4 is that positioning jack, 5 is single width steel case beam.
The specific embodiment
Following non-limiting examples is used for explanation the present invention.
As shown in Figure 1, 2, the horizontal rackwork of a kind of framing type steel case beam comprises the scalable tie-beam that is connected and the articulated joint 1 that is used for resisting two single width steel case beams, 5 unbalanced moments, and the thrustor of regulating scalable tie-beam collapsing length.As optimal way, as shown in this embodiment, scalable tie-beam comprises telescoping member 2 and the supporting member 3 of movable nested connection, telescoping member 2 activities are nested in the supporting member 3, thrustor is positioning jack 4, be located in the supporting member 3, an end and supporting member 3 are fixing, and the other end contacts with telescoping member 2.
The using method of the horizontal rackwork of aforementioned framing type steel case beam may further comprise the steps successively:
1) rackwork is positioned in the middle of the framing type steel case beam that needs positioning, its two ends are detachably fixing with a single width steel case beam 5 respectively, and namely telescoping member 2 and a single width steel case beam 5 are detachably fixing, and articulated joint 1 is detachably fixing with another single width steel case beam 5;
2) pushing tow or the contraction of control positioning jack 4, framing type steel case back is opened or shunk, framing type steel case beam separates relatively during positioning jack 4 pushing tow, when positioning jack 4 shrank, framing type steel case beam bounced back naturally relatively, when framing type steel case beam position meets the demands, pushing tow or the contraction of jack 4 stop to transpose, and fixing scalable tie-beam collapsing length at this moment, it is temporary fixed to be about to telescoping member 2 and 3 of supporting members, and this moment, framing type steel case beam was adjusted to the right place;
3) put in place when framing type steel case beam positioning, after finishing steel box beam Welding and permanent crossbeam and being in place, remove its with framing type steel case beam between be connected, and releasing fixing scalable tie-beam, namely remove the temporary fixed of 3 of telescoping member 2 and supporting members, this moment, the adjustment of framing type steel case beam was finished, and at this moment, rackwork can reuse.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
