Abstract

The invention relates to a method for lifting integrally the large structure and to the device, which mainly contains a steel pivoted wire, a fixed beam, a movable beam, a guide rail, a tool anchor, a working anchor and a jack. The steel pivoted wire crosses sequentially the working anchor, the lower- tool anchor and the upper- tool anchor from down to up; the working anchor is fixed on the bottom of the steel pivoted wire, and the lower-tool anchor is fixed on the fixed beam and the upper-tool anchor on the movable beam. The fixed beam is fixed on the supporting structure and is equipped with the jack, the top of which is equipped with the movable beam. The fixed beam connects with the movable beam by the guide rail. The execution cost with the lifting device to lift large structure is one-tenth of that with traditional lifting process, and the jack, the lifting ability of which can come up to 500t grade, is normal and acceptable to the execution company. And the device is characterized in that it is high stable, safe to worker, and the lifting speed is rapid and so on.

Description

technical field

[0001] The invention relates to the lifting of large structures, in particular to a method and device for the overall lifting of large structures, especially the overall lifting of roofs, bridges and large equipment. Background technique

[0002] With the progress of the society and the development of the economy, there are more and more applications of large structures, the spans are getting bigger and bigger, the structures are getting heavier, and the lifting heights are getting higher and higher. world attention.

[0003] At present, there are seven main installation methods for large structures: high-altitude bulk method; strip and block installation method; high-altitude sliding method; mobile bracket installation method; overall hoisting method; The high-altitude bulk method is supported by a full house of scaffolding, and the top of the scaffolding is fully paved with scaffolding boards as an operating platform. This method...
