A segmented hoisting structure and method in shipbuilding

Abstract

The invention discloses a segment hoisting structure and method in ship construction. The structure comprises two distance maintaining beams, a plurality of clamp plates and hoisting lugs. The distance maintaining beams are arranged at intervals on the deck in a thin segment having low strength. Each clamp plate is a square structure. The side edges of each clamp plate are welded to the lower endportions on both sides of each distance maintaining beam. The bottom edge of each clamp plate is welded to the deck. The clamp plates are connected with the distance maintaining beams and the deck. The clamp plates on the same side of the distance maintaining beams are arranged at intervals. The clamp plates on the opposite sides of the distance maintaining beams are arranged oppositely. Accordingto the weight and the position of the center of gravity of the segment, the hoisting lugs are welded to both sides of the distance maintaining beam at intervals. The segment hoisting structure suspends the segment by hoisting the distance maintaining beams. The hoisting structure and method ensure the structural strength during hoisting, prevent deformation, improve construction efficiency and reduce labor cost.

Description

technical field [0001] The invention relates to the field of ship hoisting, in particular to a segmented hoisting structure and method in ship building. Background technique [0002] In the field of shipbuilding, hoisting operation is an indispensable link. Whether it is equipment installation, crane test, structure hoisting, outfitting installation, etc., it is inevitable to need hoisting operations for support. In the process of shipbuilding, the hull is It is formed by "building blocks" one by one or a total section. In the process of building blocks, a lot of hoisting operations are required, and the quality of hoisting operations determines the difficulty of the subsequent process. Generally, due to The structural strength of the main hull is high and the plate is thick, so good hoisting quality can often be guaranteed during the segmental hoisting process. Measures to ensure the quality of hoisting, the conventional method is to add a large amount of reinforcement ins...

[0002] In the field of shipbuilding, hoisting operation is an indispensable link. Whether it is equipment installation, crane test, structure hoisting, outfitting installation, etc., it is inevitable to need hoisting operations for support. In the process of shipbuilding, the hull is It is formed by "building blocks" one by one or a total section. In the process of building blocks, a lot of hoisting operations are required, and the quality of hoisting operations determines the difficulty of the subsequent process. Generally, due to The structural strength of the main hull is high and the plate is thick, so good hoisting quality can often be guaranteed during the segmental hoisting process. Measures to ensure the quality of hoisting, the conventional method is to add a large amount of reinforcement inside the section to ensure the structural strength of the section hoisting, but this method has a disadvantage, that is, a large number of strengthening and dismantling work is required after the section hoisting is completed, and There is a risk of collision with equipment in the segment
