20140017059 | ASYMMETRIC INTEGRAL LIFTING CONSTRUCTION METHOD - A method for lifting an asymmetric integral construction is provided, including the steps of determining proper lifting points on a construction to be lifted according to the position relationship between the construction and a base supporter, setting a dragging point on the bottom of the construction, the dragging point being located on the extension line of the connection between the gravity center of construction and the centroid of the lifting points, determining a projection point of the dragging point on the ground, arranging a dragging device between the dragging point and the projection point, installing a lifting system at a proper position, conducting lifting operation by means of the lifting system cooperated with the dragging device, and rectifying and fixing the construction after it is in place. | 01-16-2014 |
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 |
20140346131 | Construction Apparatus and Method for Lifting Structure Integrally over the Obstacles in Vertical Direction to a Position with Different Horizontal Projection - The present invention disclosed a construction apparatus and method for lifting structure integrally over the obstacles in vertical direction to a position with different horizontal projection. The apparatus comprises two platform beams placed each other in parallel, two lifting beams laterally relative to the platform beams and a lifter equipped with the lifting beams. Push instrument kits are installed on the platform beams and the lifting beams respectively, and a plurality of sets of baffles installed on both sides of the platform beams to provide the push instrument kits with a counter-force when the push instrument kits work. When the structure encounters obstacles during the process of lifting the structure by two lifters, the posture of the structure can be altered by operating the push instrument kits and the lifters, such that the horizontal projection of the structure will be reduced and the structure can therefore be lifted over the obstacle in vertical direction. | 11-27-2014 |
20140348623 | Construction Apparatus and Method for Lifting and Sliding Object over Barrier in Horizontal Direction - The present invention disclosed an apparatus and for lifting and sliding object over barrier in horizontal direction, comprising two lifting beams that placed on supporting structures and located above object to be lifted and a barrier, and a lifter installed on the lifting beam. A hydraulic push instrument kit is installed on a lifting beam to move the shoulder beam and the lifter. The lifter connects with the object through the steel strand and a triangle transfer connector having three fixed-holds. When the steel strand encounters a barrier in horizontal direction, setting another lifting apparatus on the part of lifting beams located on the other side of the barrier, connecting another lifting apparatus with the third fixed-hold of transfer connectors | 11-27-2014 |
20150110581 | APPARATUS AND METHOD FOR LIFTING AND SLIDING A STRUCTURE ATTACHED TO THE WALL - The invention disclosed an apparatus for lifting and sliding a structure attached to the wall, comprising a lifting platform extending out over the building on the roof, and a synchronous lifting and sliding system which is arranged on the lifting platform; wherein the lifting platform comprises two platform beams extending out over the building, and a lifting beam placed on the platform beam; the synchronous lifting and sliding system comprises a hydraulic lifter arranged on the lifting beam, a hydraulic push instrument kit connected to the lifting beam, and a controller; A connecting rod is connected to one end of the hydraulic push instrument kit, and several installing holes are arranged at regular intervals on the connecting rod; The distance between the adjacent installing holes of the connecting rod matches with a stroke of the hydraulic push instrument kit; An installing ear-plate is provided on the platform beam to connect with the connecting rod. | 04-23-2015 |
