Provided is a construction method for a fully prefabricated multi-story concrete plant, the construction method may achieve full coverage of a hoisting operation of the large beam and column prefabricated components of a floor by employing a single intelligent hoisting robot, an angle change of the track devices, an angle change of a moving device, and a self-lifting device. It is not necessary to arrange a transition track at the turn of the installation route, which saves space and installation cost, and overcomes the disadvantage of high cost caused by the traditional prefabricated construction mode of multi-story concrete plant, which needs to arrange a plurality of large hoisting equipment. It may achieve the mechanization and intelligence of the whole construction process of the fully prefabricated multi-story concrete plant.

Provided is an accumulative sliding construction method of segmental track-changing for unequal-span structure, which divides the unequal-span structure into at least two sliding sections according to span variation, and a plurality of track segments corresponding to the spans of each sliding section. By providing sliders on the main truss/beam of each sliding section at positions corresponding to the track segments that each main truss/beam need to pass through, the sliding section smoothly passes through the sliding track segments to be in position; in addition, the main truss/beam of each sliding section is provided with temporary lengthening auxiliary structure or divided into an initial-mounted unit and rear-mounted units to allow the main truss/beam of each sliding section to pass through the track segments smoothly and to be in place.

The present invention disclosed an apparatus for reverse rectification, relating to the field of civil engineering technology. The apparatus for reverse rectification comprises two sets of steel plate hooks, which are reversely arranged and respectively fixed on the building and the skewed large-scale structure that needs to be rectified, and a jack which is horizontally placed on the steel plate hooks. The steel plate hooks, which are driven by the jack, push the skewed structure towards the existed building, whereby the skewed structure and the existed building can be spliced correctly. This present invention has more advantages, e.g. simple structure and convenient operability, which can improve the construction efficiency and reduce the construction costs. Therefore it can be widely used in the field of civil engineering technology. Further, the present invention also discloses a method for reverse rectification by using the apparatus.
