Problems solved by technology
[0002] For ships with superstructures made of aluminum alloy, due to the low elastic modulus of aluminum alloy, the general section is easily deformed during hoisting. During the hoisting process, a lot of deformation prevention and post-deformation correction work are required, and the deformation is difficult to correct.
Even if the hoisting method is improper, the overall section will have a large deformation, which will affect the loading accuracy of the berth and is not conducive to the shortening of the construction period
Therefore, in order to control the lifting deformation, the general aluminum alloy superstructure does not have a large overall section, which limits the application of regional shipbuilding technology

Embodiment Construction
[0030] figure 1 Shown is a schematic diagram of the general section of the aluminum alloy superstructure hoisting, the hoisting process is as follows:
[0031] Firstly, according to the weight, structural form and center of gravity of the aluminum alloy superstructure total section, determine the number of multiple lifting points, multiple lifting point positions and the overall hoisting method of the aluminum alloy superstructure total section; Two cranes 8, 9 carry out joint hoisting.
[0032] Secondly, make the hoisting hanger 6 of the general section of the aluminum alloy superstructure to control the hoisting deformation. The hoisting hanger 6 here is assembled from profiles such as channel steel, and its structure is as follows: figure 1 It is shown that three rectangles are connected in sequence, because figure 1 The total section shown is divided into three sections, that is, the first section 1 and the second section 2 that are juxtaposed on the bottom floor, and th...

The invention provides an aluminum alloy superstructure block hoisting method, which comprises the following steps of (1) determining the quantity of multiple hoisting points, positions of multiple hoisting points and an integral hoisting method of an aluminum alloy superstructure block according to the weight of the aluminum alloy superstructure block, a structural form and a gravity core; (2) producing a hoisting bracket for hoisting the aluminum alloy superstructure block; (3) designing and installing temporary reinforcement onto the aluminum superstructure block according to the integral hoisting method; (4) installing one hoisting hanger on each position of multiple hoisting points; and (5) vertically joining the hoisting hangers with the hoisting bracket through a wire cable, and utilizing the hoisting bracket to carry out the multipoint vertical hoisting. According to the hoisting method, not only can the deformation control problem for hoisting the aluminum superstructure block be solved and sectional construction of the aluminum alloy superstructure block be realized, but also the hoisting hangers and the temporary reinforcement for the hoisting are convenient to disassemble, and the block hoisting time can be shortened.
Description
technical field [0001] The invention relates to the field of shipbuilding and assembly, in particular to a method for hoisting the general section of an aluminum alloy superstructure. Background technique [0002] For ships with superstructures made of aluminum alloy, due to the low elastic modulus of aluminum alloy, the general section is easily deformed during hoisting. During the hoisting process, a lot of deformation prevention and later deformation correction work are required, and the deformation is difficult to correct. Even if the hoisting method is improper, the total section will have a large deformation, which will affect the loading accuracy of the berth and is not conducive to the shortening of the construction period. Therefore, in order to control the hoisting deformation, the general aluminum alloy superstructure does not have a large overall section, which limits the application of regional shipbuilding technology. Contents of the invention [0003] The o...
