Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the above technical solutions will be further described below in conjunction with the illustrations.

[0013] The present invention will be further described below in conjunction with the embodiments and accompanying drawings. Such as figure 1 The shown flexible anti-fatigue structure of a hull vehicle deck includes a longitudinal deck beam 1, a hull 2 ​​with several plug-in brackets, a bulkhead strong frame 3 and a half-stop strong frame 4 flexibly hinged to the hull and 5 plug-in brackets to form a deck The frame structure is characterized in that the adjacent deck beams 1 / half frame 4 are arranged longitudinally / transversely in dislocation, forming a double dislocation structure.

[0014] The anti-fatigue dislocation structure formed by dislocation of deck beam 1 and half strong frame 4 specifically includes the original dislocation: the ...

Abstract

The invention discloses a flexible anti-fatigue structure for a ship body vehicle deck. The flexible anti-fatigue structure for the ship body vehicle deck comprises a longitudinal deck beam, a ship body, a cabin wall reinforcing frame and a deck frame structure, wherein a plurality of inserting gears are arranged on the ship body; the deck frame structure is formed by flexibly hinging a half-gear reinforcing frame and the inserting gears of the ship body; the adjacent deck beams/the half-gear reinforcing frames are respectively arranged in a longitudinal direction/a transverse direction in a staggered manner to form double staggered structure. Without increasing construction difficulty and cost and affecting the normal working of ship roll-on and roll-off equipment, the fatigue strengths at the connected parts of the deck beams and ramps can be furthest enhanced, the safety of the structure can be guaranteed, and the maintenance cost of the destroyed structure can also be reduced.

Description

technical field [0001] The invention relates to a structural improvement of a hull vehicle deck. Background technique [0002] Ro-ro ships often need to set up a large number of vehicle ramps connecting each deck because they need to meet the needs of vehicles passing through each deck. In order to meet the requirements of the ramp layout, a large number of openings will be produced on the vehicle deck. These large openings affect the transverse continuity of the vehicle deck, and form stress concentration at the intersection of the vehicle deck beam and the longitudinal bulkhead of the ramp. The fatigue strength here is difficult be guaranteed. Feedback from actual ship operation shows that the ramp is an area where fatigue cracks frequently occur, and special attention should be paid to design and construction. [0003] In order to meet the fatigue strength here, it is usually adopted to strengthen and increase the thickness of members or brackets, etc. Such strengthenin...
