Description
Technical Field
The invention relates to the technical field of folding edge design of deck platforms.
Background
In the prior art, the line type of the ship outer plate changes smoothly, the intersection angle formed by the deck platform and the line type of the outer plate is large, and the construction space is wide. With the deep research of the energy efficiency of ships, the requirements on the line type of the outer plate are higher and higher, so that the line type of the outer plate of the ship is changed very severely in a local area. In order to obtain good hydrodynamic performance, the line type of the current high-performance ship outer plate mostly mainly takes the line type shrinkage of the tail area as fast and the line type thin, which often causes the intersected space of the line type of the deck platform and the outer plate to be long, narrow and small, and if the design of the conventional deck platform is adopted, even if the edge of the deck platform is provided with a construction process hole, the requirement of the site construction space is difficult to meet. How to effectively solve the problem of construction space existing between theoretical design and actual construction is the research direction of the applicant.
Disclosure of Invention
The invention aims to provide a folding edge design method of a deck platform, which can enlarge the construction space at the intersection of the deck platform and an outer plate and solve the problem that the construction of the intersection area of the deck platform and the outer plate is difficult.
The technical scheme for realizing the purpose is as follows:
a method of designing a hem for a deck platform, comprising:
marking the position of a deck platform in an outer plate line diagram of a target area;
selecting proper number and positions of folding points by combining a top view of the deck platform, and determining folding positions according to the folding points;
and step three, selecting a proper flanging angle and determining a typical section form.
Preferably, the target area refers to: and determining the area with construction difficulty at the intersection of the deck platform and the outer plate according to the line type of the outer plate and the height of the deck platform.
Preferably, in the second step, the folding points are connected in sequence by line segments to obtain the folding edge position of the deck platform.
Preferably, the butt joint mode of the deck platform folding edge at the middle folding point and the connection mode of the folding edge at the front and rear folding points are flexibly selected according to the structural arrangement.
Preferably, the folding angle is selected to be 45 degrees.
The invention has the beneficial effects that: the method can meet the linear optimization requirements of most external plates, improves the structural space of a narrow area, meets the requirements of site construction, and avoids a large number of structural construction process holes; the structural arrangement difficulty of the high-performance ship is reduced. The method is particularly applied to the condition that the line type change of the ship outer plate is large, and the large-range construction is difficult when the intersection angle formed by the deck platform and the outer plate line is small, and can effectively solve the structural arrangement problem after the line type energy efficiency of the ship outer plate is optimized.

Referring to fig. 1-3, the folding design method of deck platform of the present invention comprises the following steps:
marking the position of a deck platform in an outer plate line diagram of a target area, and measuring the included angle between a deck and an outer plate at a typical rib position;
the target area means: and determining the area with construction difficulty at the intersection of the deck platform and the outer plate according to the line type of the outer plate and the height of the deck platform.
And step two, selecting proper folding point quantity and positions (reducing folding area as much as possible) by combining a top view of the deck platform, and then connecting the folding points in sequence by using line segments to obtain folding positions of the deck platform, wherein three folding points (A, B, C) are selected to determine two folding lines as shown in the figure.
The butt joint form of the deck platform folding edge at the middle folding point and the connection form of the folding edge at the front and rear folding points can be flexibly selected according to structural arrangement.
And thirdly, selecting a proper flanging angle by combining the construction experience of the site narrow space, and determining a typical section form, wherein when the flanging angle is selected to be 45 degrees, the space formed by the outer plate and the flanging of the deck can meet the site construction requirement as shown in the figure example.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
