Abstract
The present invention relates to a kind of flexible carrier device for steel truss beam bridge cantilever construction, comprise flexible steel bracket, steel stool pressure sensor and adjustment jack, flexible wind bracket end face four angle points are placed respectively a set of steel stool pressure sensor and adjustment jack, in order to jacking top girder steel and Real-Time Monitoring jacking force and carry out top power adjustment in real time.Flexible steel bracket comprises longitudinal and transverse beam, longitudinal and transverse link rod, column, diagonal brace, bridging, column upper end is fixedly connected with longitudinal and transverse beam, middle part is fixedly connected with longitudinal and transverse link rod, is connected to diagonal brace, is connected with bridging between longitudinal and transverse beam and longitudinal and transverse link rod between column and longitudinal and transverse beam.The present invention, by the flexible steel bracket on cushion cap with by steel stool pressure sensor and the whole series top power adjustment System of forming of adjustment jack, can solve the problem of pier top horizontal force difference, can ensure again the vertical force controlled of girder steel in work progress and compensation.This device is easy and simple to handle, and it is convenient to control.
Description
Technical field
The present invention relates to a kind of steel truss beam bridge cantilever construction device, especially a kind of bracket system for Large Steel truss bridge cantilever construction.
Background technology
In Large Steel truss bridge cantilever construction, owing to being subject to the comprehensive factor restriction such as structure stiffness by itself intensity, orographic condition, hydrology traffic, construction period, economic factor, except applying traditional temporary measure and coordinating installation, mostly to suit measures to local conditions to use special temporary measure.But at present, the temporary measure more complicated used in Large Steel truss bridge cantilever construction or heaviness, have impact on the using function of continuous cantilever construction to a certain extent.
Summary of the invention
The present invention will solve the technical problem in the construction of large span steel truss beam bridge continuous cantilever, and provides a kind of flexible carrier device for steel truss beam bridge cantilever construction of handled easily.
Technical scheme of the present invention is: a kind of flexible carrier device for steel truss beam bridge cantilever construction, comprise flexible steel bracket, steel stool pressure sensor and adjustment jack, be characterized in: flexible wind bracket end face four angle points are placed respectively a set of steel stool pressure sensor and adjustment jack, in order to jacking top girder steel and Real-Time Monitoring jacking force and carry out top power adjustment in real time.
Flexible steel bracket comprises longitudinal and transverse beam, longitudinal and transverse link rod, column, diagonal brace, bridging, column upper end is fixedly connected with longitudinal and transverse beam, middle part is fixedly connected with longitudinal and transverse link rod, is connected to diagonal brace, is connected with bridging between longitudinal and transverse beam and longitudinal and transverse link rod between column and longitudinal and transverse beam.
Useful achievement of the present invention is: by the flexible steel bracket on cushion cap with by steel stool pressure sensor and the whole series top power adjustment System of forming of adjustment jack, the problem of pier top horizontal force difference can be solved, the vertical force controlled of girder steel in work progress and compensation can be ensured again.This device is easy and simple to handle, and it is convenient to control.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with instantiation, set forth the embodiment of patent of the present invention further.Should be understood that these examples are only not used in for illustration of patent of the present invention the scope limiting patent of the present invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after the content of reading patent teaches of the present invention, these equivalent form of values fall within the application's appended claims limited range equally.
As Fig. 1, shown in 2, the flexible carrier device for steel truss beam bridge cantilever construction of the present invention, comprises flexible carrier 1, steel stool pressure sensor 2, adjustment jack 3.
Design, process the flexible steel bracket 1 of a space structures at cushion cap end face according to pier shaft planform and upper steel girder truss node location, flexible steel bracket 1 end face four angle points are just to the node location of first internode about upper steel girder truss, flexible steel bracket 1 end face four angle points are arranged a set of steel stool pressure sensor 2 and adjustment jack 3 respectively, in order to jacking top girder steel and Real-Time Monitoring jacking force and carry out top power adjustment in real time.
Flexible steel bracket 1 comprises longitudinal and transverse beam 4,5, longitudinal and transverse link rod 6,7, column 8, diagonal brace 9, bridging 10.Column 8 upper end is fixedly connected with longitudinal and transverse beam 4,5, and middle part is fixedly connected with longitudinal and transverse link rod 6,7, and column 8 and longitudinal and transverse beam 4, be connected to diagonal brace 9 between 5, and longitudinal and transverse beam 4,5 and longitudinal and transverse link rod 6, be connected with bridging 10 between 7.
Utilize the jacking of jack to make bracket four point symmetry be subject to a calculated value power, the size of its force value is as the criterion with sensor reading, if deviation exceedes calculating, permissible value can utilize jack to adjust in real time.
Concrete operation method of the present invention:
1, often complete to five internodes across each free cantilever erection, 1 four jiaos, the flexible steel bracket that the other installation in advance of pier is good arranges that four to adjustment jack 3 and four steel stool pressure sensors 2.
2, start hydrant cart and adjustment jack top 3 is raised to calculated value, pad between steel stool pressure sensor 2 and Steel Truss Beam with billet, each time during jacking, the strict stressed synchronism controlling four points all around, guarantees that flexible steel bracket 1 is overall stressed.
3, after five internodes, free cantilever erection often completes half internode and carries out the inspection of steel stool pressure sensor 2 pressure reading, adjusting, making the stressed all the time in controlled area charactert of flexible steel bracket 1 if deviation exceedes permissible value with regard to utilizing adjustment jack 3 in time.
