The invention belongs to the technical field of bridge construction, and particularly relates to a rising and falling beam operation method for synchronous jacking of beam bodies. The method comprises a jacking mechanism, and the rising and falling beam operation method for synchronous jacking of beam bodies is operated through the jacking mechanism. The jacking mechanism comprises a plurality of pier bodies, four pouring grooves are formed in the upper sides of the pier bodies, the four pouring grooves are distributed in a rectangular shape, a foundation bolt is placed in each pouring groove, the upper end of the foundation bolt is located on the upper side of each pouring groove, concrete is poured in the pouring grooves, a steel base plate is placed on the upper side of each pier body, four through holes are formed in the edge of the steel base plate, the through holes correspond to the foundation bolt in position, the upper side of the foundation bolt penetrates through the through hole, the upper end of the foundation bolt is in threaded connection with a fixing nut, and the upper side of the steel base plate is fixedly connected with a mounting seat. The jacking mechanism is controlled to work through a central control computer, so that the beam bodies can be jacked synchronously, and internal damage caused by uneven stress can be avoided.
Description
technical field [0001] The invention relates to the technical field of bridge construction, in particular to an operating method for lifting and falling girders in which the girder bodies are simultaneously jacked up. Background technique [0002] In recent decades, with the continuous development of bridge design, manufacturing and erection technology and construction materials, more and more bridges have been constructed. [0003] In the process of bridge construction, it is necessary to jack up the beam body for installation and processing, but the stress on each position of the beam body is uneven during the lifting process of the existing beam body, which may easily cause internal damage, and due to the length of the beam body Longer, it is not easy to jack up the beam body synchronously. Contents of the invention [0004] The purpose of the present invention is to provide a lifting beam operation method for synchronous lifting of the beam body, so as to solve the pr...
