20140305069 | APPARATUS AND METHOD FOR REVERSE RECTIFICATION - 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. | 10-16-2014 |
