Detailed Description

The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.

As shown in fig. 1 and 2, a new mooring strengthening misalignment design structure is provided on a deck 10 where a mooring device is located, and includes a planking 11 located below a base 20 of the mooring device, and the planking 11 is embedded on the deck 10.

The deck 10 comprises a socket plank 11 and other deck boards 12 around the socket plank; the thickness of the peg board 11 is greater than the thickness of the other deck boards 12.

The inserted thick plate 11 and the other deck plate 12 are connected by welding.

A base web 30 is provided between the mooring base 20 and the spigots 11.

The top of the base web 30 is fixedly connected to the mooring equipment base 20; the bottom of the base web 30 is secured to the peg board 11. The base web 30 is perpendicular to the mooring base 20.

The base web 30 has soft toe ends 31 at both ends. The soft toe end 31 has a concavely curved end edge.

The ends of the base web 30 each extend outside the mooring base 20. The base web 30 does not have a bottom that extends beyond the inset panel 11.

The bottom of the inserted thick plate 11 is fixedly provided with a plurality of reinforcing materials 13.

The strengthening materials 13 are distributed along the width direction of the ship and are parallel to each other; the stiffening materials distributed along the width direction of the ship are also called transverse stiffening materials.

Or the reinforcing materials 13 are distributed along the ship length direction, and the reinforcing materials are parallel to each other. The reinforcing materials distributed along the length direction of the ship are also called longitudinal reinforcing materials.

In this embodiment, the bottom of the thick insertion plate is provided with the stiffening material distributed along the ship width direction and the stiffening material distributed along the ship length direction.

The invention consists of three parts.

The first part is a deck plate which is locally inserted thick in the strengthening area of the mooring equipment, namely a thick plate. By using the inserted thick plate, the situation that the yield limit of the material is broken through due to local stress concentration can be avoided.

The second part is that the end of the mooring equipment base web plate adopts a soft toe design so as to effectively relieve the stress concentration problem in the case of an unset design.

The third part is the function of arranging some strengthening materials along the width direction or the length direction of the ship in an encrypted way to realize uniform transmission of the load above.

In a strengthening area of the mooring equipment, because the load of the mooring equipment is not particularly large generally, the base is arranged, the load of the mooring equipment can be uniformly transmitted to a deck due to the existence of the base web plate, and the stress at the end part of the base web plate is generally large, so that the stress concentration problem at the end part can be effectively relieved by adopting a soft toe design instead of a direct connection design.

The deck below the mooring is directly loaded by the mooring and the spigots in the mooring area alleviate the stress concentration problem. The transverse strengthening materials and the longitudinal strengthening materials which are tightly arranged below the deck form a fine network, so that the load transmitted by the deck plate can be uniformly transmitted to the strengthening member, and the strengthening effect is further realized.

The mooring 40 can be flexibly arranged in a given mooring reinforcement area when the mooring is installed, regardless of the position of the under-deck reinforcement members.

The invention is characterized in that the reinforcement under the deck and the mooring equipment above the deck do not need to be completely aligned, and meanwhile, the structural strength can be ensured to meet the requirement.

The invention solves three main technical problems: 1. in the conventional production construction of the ship, the alignment reinforcement of the mooring equipment below the deck is generally made firstly, and the mooring equipment above the deck is made at last, so that the requirement on the alignment precision is high, sometimes, the alignment reinforcement of the mooring equipment below the deck and the mooring equipment above the deck cannot be aligned well, and certain safety risk exists; 2. in the later stage of ship construction, as the alignment reinforcement below the deck cannot be changed, the mooring equipment above the deck cannot be adjusted according to the actual condition, which is not beneficial to the flexibility of arrangement of the mooring equipment; 3. how to still ensure the strength of the structure under the condition that the mooring equipment and the lower reinforcement are not completely aligned.

The invention considers the design without alignment during the initial design, firstly a range is given, the strengthening scheme of the mooring equipment is made in the range, and the strength requirement of the strengthening design under the mooring equipment can be met as long as the mooring equipment is finally arranged in the range.

The invention does not need to meet the requirements of strengthening below the deck and strictly aligning mooring equipment above the deck, and brings great convenience and flexibility to construction while ensuring the requirement of structural strength.

Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
