Description

A kind of bridge pad is changed operating platform
Technical field
The present invention relates to a kind of bridge pad and change operating platform, especially relate to a kind of operating platform of setting up on stake column pier top, belong to bridge inspection and maintenance construction equipment device technique field.
Background technology
Along with the bridge increase of service life; Phenomenons such as the bearing off normal of existing bridge or bearing damage are more and more common and outstanding; Influenced the normal use of bridge; Need carry out jacking to bridge, and then carry out bearing replacement, pinner reparation etc. and safeguard construction operation, therefore press for a kind of safe, construction operation platform is accomplished above-mentioned work easily.
The lifting platform that bridge pad replacing is at present adopted mainly contains: (1) utilizes former Bridge Pier, bent cap as jacking counter-force support platform; This scheme easy construction; But receive the restriction of bridge itself and the influence of site operation environment, be not suitable for all types bridge; (2) set up support pier, support as jacking counter-force support platform, this scheme construction has high input and poor reliability; (3) utilize former bridge bearing platform to do the basis and set up reaction frame as jacking counter-force support platform, this scheme constructional difficulties, reliability cannot say for sure to demonstrate,prove; (4) enlarge former bridge pier diameter, utilize bridge pier column as jacking counter-force support platform after increasing the pier top area, this scheme reliability is higher, but it is loaded down with trivial details to construct, and can produce bridge construction to destroy, and after the concreting maintenance period longer.
Summary of the invention
In order to overcome the deficiency of prior art, the object of the present invention is to provide a kind of safety, reliability high, to the destructive little bearing replacement operating platform of existing bridge construction.
The present invention realizes through following technical scheme:
A kind of bridge pad is changed operating platform, it is characterized in that, comprises pier stud cuff, floor and top board; Described pier stud cuff is set in the periphery of bridge pier column upper end, and described top board is a circular configuration, and it is arranged on the top of bridge pier column and pier stud cuff; Described floor is provided with a plurality of; Be distributed on the periphery of pier stud cuff, the top of floor is connected with top board, and fixing through welding between described pier stud cuff, floor and the top board.
Described bridge pad is changed operating platform and is set to three, and 119 ° at every central angle connects into integral body through high-strength bolt between these three; Be that described top board is provided with three, every central angle is 119 °, and described pier stud cuff also relative set be three; Every central angle also is 119 °; Adopt welding fixing between top board and pier stud cuff and the floor, and connect through high-strength bolt between the pier stud cuff piece, the aperture of described high-strength bolt is 10-25cm.
Further, the material of described top board, floor and pier stud cuff is a steel plate.
Wherein, the thickness of described top board, floor and pier stud cuff is 10-25mm, and the internal diameter of described pier stud cuff is 80-160cm, highly is 40-100cm, and the internal diameter of pier stud cuff is slightly larger than the diameter of bridge pier column, is as the criterion being fixed on the bridge pier column.And the external diameter of said top board is than the big 15-25cm of diameter of bridge pier column; The top board centre according to actual conditions, is cut to circle or quadrangle; Top board must be able to be shelved on the end face of bridge pier column; Make top board can be set in bridge pier column top, and can not be inserted in bridge pier column, job platform is provided for the jacking jack is installed.
In addition, described depth of floor is than the little 10-20cm of height of pier stud cuff, and concrete quantity is looked the needs of layout jack on the top board and decided, and generally by 5 °-30 ° central angle, is evenly arranged on the circumference of pier stud cuff.
The invention has the beneficial effects as follows: after the present invention has enlarged bridge pier top application work industry area through the pier stud cuff of setting up on the bridge pier column top; As the temporary platform that the jacking jack is set; Its reliability is high; Owing to need not bridge pier column carried out processing such as bar planting, the destruction that therefore existing bridge pier column is produced is less.
