Description
Technical field
The utility model belong to large-scale steel box-girder install after adjustment technology, be specifically related to a kind of large-scale steel box-girder in pier coping portion lifting after the accurate rackwork of installation.
Background technology
Growing along with construction industry and technology, China is in the coastal construction carrying out multiple marine elevated bridge.In order to realize high efficiency and the construction of high performance overhead girder, existingly occurred adopting the large sections steel box-girder had compared with large span, its length has reached more than 80 to 130 meters, and weight is up to more than 2000 tons.Because Large-span Steel Box Beam is applicable to marine elevated bridge more, therefore how to carry out lifting that is steady and precise positioning and transpose afterwards as the key of bridge Construction Technology.
Because the large-scale ship that hangs can occur swing thus cause large sections steel box-girder cannot realize once location and installation accurately in hoisting engineering, therefore the precise positioning after placing is needed to adjust, but because the deadweight of steel box-girder is larger, the mode being difficult to be promoted by transverse integral realizes its stable displacement at pier coping portion, and the huge friction simultaneously between large-scale steel box-girder and bridge pier also can cause the stability influence to bridge pier body.
Utility model content
The utility model provides a kind of reasonable in design, can install the accurate rackwork of installation of the large-scale steel box-girder of rear positioning to large-scale steel box-girder, and the stability of its adjustment is high, and cost is low, can realize the flexible modulation of all directions.This device effectively simplifies the Operating Complexity that lifting is installed, and significantly improves efficiency of installing and transpose.
The technical scheme that the utility model adopts is as follows:
A kind of accurate rackwork of installation of large-scale steel box-girder, it is characterized in that described installation adjuster comprises the temporary support being placed in pier coping portion, the lower surface of this temporary support is connected with top of bridge pier end face by rigid contact sliding part, temporary support is by the large-scale steel box-girder of upper end, a support portion pushing tow, the surrounding of described support portion is provided with adjusts beam fluid pressure drive device, and this tune beam fluid pressure drive device drives described temporary support to carry out slip along described rigid contact sliding part and arranges.
In detailed description of the invention, described rigid contact sliding part comprises the sliding way steel plate, tetrafluoro plate, corrosion resistant plate and the glide path steel plate that superpose setting successively, and described glide path steel plate to be connected with top of bridge pier end face by cushion block and to arrange.
In one embodiment, the surrounding of described rigid contact sliding part is provided with slideway block, described slideway block slides arrange and adjusts beam fluid pressure drive device, and this tune beam fluid pressure drive device level is arranged to driving temporary support.
In another embodiment, described tune beam fluid pressure drive device is the hydraulic jack that horizontal four direction is arranged respectively.
Again in an embodiment, the support portion of described temporary support comprises a concrete pedestal, and described this concrete pedestal of tune beam fluid pressure drive device horizontal drive is arranged.
In one embodiment, the upper end of described concrete pedestal is provided with a rigidity sandbox, and this rigidity sandbox side is provided with sand export, large-scale steel box-girder described in the top pushing tow of this rigidity sandbox.
In another embodiment, the upper end of described rigidity sandbox is superimposed with adjustment billet, and billet upper end is provided with rubber shock-absorbing plate.
After the large-scale steel box-girder of pier coping portion completes first location, the accurate rackwork of the installation of this large-scale steel box-girder both can have been adopted to carry out fine adjustment, can according to the beam section weight of large-scale steel box-girder, at the two ends of beam section, respectively temporary support is set, the tune beam fluid pressure drive device that the surrounding of temporary support is arranged optionally can drive temporary support from four direction, makes temporary support rely on the vertical or horizontal fine adjustment of the realization of rigid contact sliding part and large-scale steel box-girder.
The beneficial effects of the utility model are, the installation accurate rackwork reasonable in design of this large-scale steel box-girder, can install rear positioning to large-scale steel box-girder, and stability of its adjustment is high, and cost is low, can realize the flexible modulation of all directions.This device effectively simplifies the Operating Complexity that lifting is installed, and significantly improves efficiency of installing and transpose.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
