Embodiment approach
[0028] In further embodiments of the present invention, see Figure 1 to Figure 3 As shown, the end of the deck beam 1 is arc-shaped.
[0029] In a further embodiment of the present invention, the end of the deck web 1 is aligned with the web of the right-angle groove 21 and welded. The end of the deck beam 1 is enlarged by a circular arc, and welded in alignment with the web of the right-angle groove 21, which ensures the effective connection between the deck beam 1 and the trough bulkhead 2, avoids the setting of deck longitudinal pipes, and reduces the loss of cabin capacity and reduce structural weight.
[0030] In a further embodiment of the present invention, the numbers and relative distances of the deck web 1 , right-angled slots 21 and oblique-angled slots 22 can be changed accordingly according to the length of the cargo hold.

The invention discloses a large spacing deck web crossbeam and groove-type longitudinal bulkhead connecting structure. The large spacing deck web crossbeam and groove-type longitudinal bulkhead connecting structure comprises deck web crossbeams and groove-type bulkheads, wherein one deck web crossbeam is arranged between each two web frame spacing; each groove-type bulkhead comprises a right anglegroove and a bevel angle groove, a web of each right angle groove is aligned with a web of the corresponding deck web crossbeam, and the bevel angle grooves are located between the multiple deck webcrossbeams or between the deck web crossbeams and transverse bulkheads. According to the large spacing deck web crossbeam and a groove-type longitudinal bulkhead connecting structure, by arranging thelarge spacing deck web crossbeams, the number of the web crossbeams in a cabin is decreased, cabin washing shadows are reduced, the efficiency of a single tank washing machine is improved, and the investment cost is reduced; by arranging the groove-type bulkheads formed by combining the right angle grooves and the bevel angle grooves, the right angle groove webs are aligned with and welded to theweb crossbeam webs, effective connection between the web crossbeams and the groove-type longitudinal bulkheads is ensured, arranging of deck longitudinal pipe tunnels is avoided, the cabin capacity loss is reduced, and the structure weight is reduced.
Description
technical field [0001] The invention relates to the technical field of trough-type longitudinal bulkheads, in particular to a connection structure between a deck web beam and a trough-type longitudinal bulkhead. Background technique [0002] The bunkering ship is a special product oil tanker with the function of bunkering and replenishing the ship. [0003] For product oil tankers, there are many types of oil loaded on them, and the cargo tank needs to be thoroughly flushed every time the oil product is changed to avoid contamination of the oil product. In order to achieve the purpose of efficient tank washing, the internal structure of the cargo tank is required to be smooth and flat, and to avoid the shadow of tank washing. Usually, the deck frame is set above the upper deck and adopts the form of a grooved bulkhead. [0004] However, considering the special functional requirements of the bunkering ship, when the crew performs ship-to-ship bunkering operations on the deck...
