Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] see Figure 1-3 , the hemming design method of the deck platform of the present invention, comprises the following steps:

[0019] Step 1: mark the position of the deck platform on the line diagram of the outer plate in the target area, and measure the angle between the deck and the outer plate at the typical rib position;

[0020] The target area refers to: according to the line shape of the outer plate and the height of the deck platform, it is determined that there is difficulty in construction at the intersection of the deck platform and the outer plate.

[0021] Step 2. Based on the top view of the deck platform, select the appropriate number and position of the folding points (reduce the folding area as much as possible), and then use the line segments to connect the folding points in turn to obtain the folding position of the deck platform. As shown in the fi...

Abstract

The invention discloses an edge folding design method for a deck platform. The edge folding design method comprises the steps of marking the position of the deck platform in an outer plate linear graph of a target area; in combination with a top view of the deck platform, selecting proper number and positions of folding points, and determining folding edge positions according to the folding points; and selecting a proper edge folding angle, and determining a typical section form. The construction space of the intersection of the deck platform and an outer plate can be expanded, and the problem that the intersection area of the deck platform and the outer plate is difficult to construct is solved.

Description

technical field [0001] The invention relates to the technical field of hemming design of a deck platform. Background technique [0002] In the past, the line shape of the ship's shell plate changed smoothly, and the intersection angle between the deck platform and the line shape of the shell plate was relatively large, so the construction space was ample. With the in-depth study of ship energy efficiency, the requirements for the line shape of the outer shell are getting higher and higher, which leads to drastic changes in the line shape of the ship shell in local areas. In order to obtain good hydrodynamic performance, most of the current high-performance ships' outer plating line types are mainly characterized by fast shrinkage and thin line shape in the tail area, which often results in a long and narrow space where the deck platform and the outer plate line shape intersect Small, if it is designed according to the conventional deck platform, even if the construction pro...
