Abstract

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.

Claims

1. An apparatus for reverse rectification, comprising two sets of steel plate hooks and a jack being configured between the two sets of steel plate hooks, wherein each steel plate hook has two opposite ends, one end is a bent-up end while the other end is welding end;

The two sets of steel plate hooks are reversely placed, wherein the Welding ends of the first set of steel plate hooks are fixed onto the existed building by welding, and the bent-up ends thereof reach out towards a skewed structure that needs to be rectified, while the welding ends of the second set of steel plate hooks are fixed onto the skewed structure by welding, and the bent-up ends thereof reach out towards the existed building;

The space between the bent-up ends of two sets of steel plate hooks is adapted to receive the jack.

2. The apparatus of claim 1, wherein each set of the steel plate hooks comprises two steel plate hooks, and two hooks of the second set of steel plate hooks are set abutting each other while two hooks of the first set of steel plate hooks are set separately with interval where the two hooks of the second set of steel plate hooks are placed.

3. The apparatus of claim 1, wherein the bent-up ends of the first set of steel plate hooks are equipped with a transition plate which is used for increasing the accessible area between the pedestal of the jack and the bent-up ends of the first set of steel plate hooks.

4. The apparatus of claim 1, wherein the jack is a screw jack or a hydraulic jack.

5. A method of using the apparatus of claim 1, comprising the steps of:

welding two steel plate hooks of the first set of steel plate hooks onto the edge of an existed building, wherein the two steel plate hooks are at a certain distance one another, and the bent-up ends of the first set of steel plate hooks reach out towards a skewed structure that needs to be rectified;

welding two steel plate hooks of the second set of steel plate hooks onto the edge of the skewed structure that needs to be rectified, wherein the bent-up ends of the second set of steel plate hooks reach out towards the existed building;

the first and second sets of steel plate hooks are reversely placed and the second set of steel plate hooks are placed between the first set of the steel plate hooks;

setting a transition plate over the bent-up ends of the first set of steel plate hooks, said transition plate is used for increasing the accessible area of the bent-up ends;

placing a jack horizontally on the space between the two sets of steel plate hooks, wherein the pedestal of the jack sustains the transition plate, and the head of the jack sustains the bent-up ends of the second set of steel plate hooks; and

actuating the jack, the head of the jack extends, and the jack pushes the bent-up ends of the two set of steel plate hooks away from each other, the skewed structure fixed to the welding ends of the second set of steel plate hooks will be moved towards the existed building fixed to the welding ends of the first set of steel plate hooks until the desired position, then the structure can be fixed to the existed building properly.
