Embodiment Construction

[0012] In order to meet certain functional requirements, the outer bottom of the ship design adopts an inclined design. If the inner bottom still adopts the conventional designed horizontal layout, the inner and outer bottoms will not be parallel, and the determination of the construction coordinates of the inner and outer bottoms is very complicated. The connecting plates between them are all trapezoidal plates. Since the plates ordered by the steel mill are all rectangular plates, several more cutting processes are required. Moreover, the cut side plates cannot be reused, and the construction cost will be greatly increased.

[0013] The present invention as image 3 , 4 , 6, the flat outsole 1 and the flat insole 3 respectively extend to the side by connecting the sloping outsole 6 and the sloping insole 5 through knuckles. The advantage of the parallel design of the outsole and the insole is that it is convenient to arrange the structure and facilitate the on-site construct...

Abstract

The invention discloses a ship with equant oblique double-layer bottoms. The ship comprises flat outer bottoms (1) and flat inner bottoms (3). The flat outer bottoms (1) and the flat inner bottoms (3) are parallel to the bottom of the ship and are respectively connected with oblique outer bottoms (6) and oblique inner bottoms (5) so as to be connected to shipboards, and the oblique outer bottoms (6) are parallel to the oblique inner bottoms (5); bottom longitudinal girders (2) are arranged among folded corners of the flat outer bottoms (1) and the oblique outer bottoms (6) and folded corners of the flat inner bottoms (3) and the oblique inner bottoms (5). The bottom longitudinal girders (2) are aligned with a longitudinal bulkhead (4) (if the longitudinal bulkhead is available), the folded corners of the inner bottoms and the outer bottoms are equally divided by the bottom longitudinal girders (2), coordinates of the folded corners of the inner bottoms are consistent with coordinates of upper end points of the bottom longitudinal girders (2), and coordinates of the folded corners of the outer bottoms are consistent with coordinates of lower end points of the bottom longitudinal girders (2). The ship has the advantages that a method for arranging the bottom longitudinal girders at folded corner points is applied, various structural angles are reasonably arranged by the aid of an equant included angle principle, accordingly, loads can be effectively transmitted, stress concentration can be reduced, the structural strength of the ship can be improved, and a technology can be simplified.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, and more specifically, relates to a double-bottom connection method in a double-bottom ship. Background technique [0002] Such as figure 1 , 2 The existing ships shown in 5 apply the design of horizontal double bottom, and the flat outer bottom 1 and the flat inner bottom 3 are arranged in parallel; figure 1 , there is no bottom stringer 2 between the flat outsole 1 and the flat insole 3 . Such as figure 2 , Bottom girders 2 are arranged between the flat outer bottom 1 and flat inner bottom 3 , and the bottom girders 2 are supported below the longitudinal bulkhead 4 . [0003] The problem is that in order to meet certain functional requirements, the transitional connection between the outer bottom and the side of the ship design adopts a partially inclined design, such as image 3 , 4 , cannot be fully applied figure 1 , 2 The connection form shown, so the original connection form ...
