Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and particularly relates to a trunking closing plate for a container ship and a method for using the trunking closing plate for a container ship. Background Art

[0002] At present, in order to speed up the shipbuilding process, many shipyards adopt the tandem building method, that is, building half ships while building the whole ship. After the whole ship is launched, the half ship is then completed into a whole ship, and at the same time, another half ship is built, and so on, which speeds up the shipbuilding pace. Whether it is a bulk carrier or a container ship, a trunking is also provided at a position near the center of the bottom section of the hull, and the trunking runs through from the bow to the stern, and a trunking closing plate is generally assembled at the opening of the trunking.

[0003] The original method was to hoist a plate slightly larger than the trunking and directly install and weld it at the trunking opening to play a sealing role and prevent water from entering the trunking. After the whole ship is launched, the half ship is landed on the pier in place, and then the plate is cut off using a cutting torch, resulting in very serious waste. Now, a new type of trunking closing plate has been developed. Rubber and turnbuckles are installed on the steel plate to seal the trunking opening. Without the need for electric welding, only simple operations can play a sealing role. However, the current new type of trunking closing plate also has certain defects. It is relatively long and extremely prone to deformation, and it is also very difficult to hoist and transport. Summary of the Invention

[0072] According to the structure described above, a closed chamber is formed by enclosing the support portion 41, the pressing portion 42 and the two sealing portions 43, and the docking seam of the two cover members 1 is located in this closed chamber, which plays a role in sealing the docking seam and further improves the sealing performance.

[0073] Further, preferably, as Figures 1 to 3 shown, any one of the sealing portions 43 is connected to both the support portion 41 and the pressing portion 42 to form an integral body, which has high structural strength and is not easily damaged. Of course, it is not limited to this, and the sealing portion 43 can also be only connected to the support portion 41 or only connected to the pressing portion 42.

[0074] In this embodiment, preferably, as Figure 6 and Figure 7As shown, the pressing member 4 further includes a first reinforcing portion 44 and a second reinforcing portion 45. Among them, the first reinforcing portion 44 is disposed on one side of the supporting portion 41, the second reinforcing portion 45 is disposed on the other side of the supporting portion 41, and the second reinforcing portion 45 is connected to the supporting portion 41 and the pressing portion 42 respectively.
