Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation examples in order to express the structural features and specific applications of the present invention more clearly, but this should not limit the protection scope of the present invention.

[0019] Such as figure 1 with figure 2 As shown, the carrying method of the side structure of the present embodiment includes the following steps:

[0020] The first step is to position the side structures. The cranes are used to position the two side structures. The two side structures are placed parallel to each other. The relative dimensions of the two side structures 1 are ensured through positioning. The location mainly refers to the front and rear end faces of the two structures 1 having the same planarity ≤ 5mm, the height synchronization ≤ 5mm, and the front and rear width spacing conforming to the tolerance requirements of the design d...

Abstract

The invention discloses a mounting method of a side structure body, which comprises the following steps: the first step, positioning the side structure body, using a crane to first position the two side structure bodies, and the two side structure bodies are connected to each other Placed in parallel, the second step is on-site tooling installation, the two ends of the distance-keeping beam are respectively welded to the inner side of the side structure, and the distance-keeping beam and the side structure are vertically connected to each other. The third step is to draw the margin According to the positioning value of the measured side structure body in the first step and the theoretical value required for the side structure body to be installed in place, draw a margin for the part of the side structure body that needs to be trimmed, and The margin is cut off. The fourth step is final positioning. Use the pump to adjust the front and rear positions of the side structure. After the adjustment is in place, the position of the frame of the entire side structure is fixed by constraint welding to complete the final positioning. The distance-keeping steel girder of the invention increases the overall strength of the large-open cargo hold and reduces the accumulated errors in the hull construction process.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for loading a side structure applied to a large-open cargo hold area. Background technique [0002] During the construction of ships, cranes, as the core construction resources, play a pivotal role. If the crane resources can be released as much as possible during the construction process, the construction efficiency can be improved. The traditional positioning method requires two cranes to hoist a hull structure. The crane is used for the first time to mark the margin line of the positioning structure, and the structure is hoisted in place after trimming the margin for the second time. [0003] The traditional hoisting method applied to the side structure of the large opening cargo hold area is prone to inward or outward tilting deformation during the construction process, especially during the welding process, such deformation is more obvious.
