Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aggregate structure suitable for a relatively large ship.

[0002]

[Prior Art]

 Generally, in a relatively large ship, aggregates are arranged on the inner surface of the outer plate that constitutes the hull in order to provide the hull strength. As shown in FIG. 6, if one example is shown, the hull 1 is composed of an upper deck 2, a bottom 3 and both side plates 4 and 5, and as shown in FIG. Is provided with a plurality of longes 6 extending in the vertical direction and a girder 7 arranged at a predetermined interval, and a floor 8 extending in the lateral direction is arranged so as to intersect with the longes 6 and the garter 7. A stiffener 9 is provided on the side surface of the floor 8, and both ends 9a and 9b of the stiffener 9 are formed into clips, and the upper and lower ends thereof are abutted against the longe 6 and the like to be an aggregate. The stiffener 9 is provided to transmit the force applied to the long 6 to the floor 8 and to prevent the floor 8 from buckling.

The stiffener 9 is provided for transmitting the force applied to the longe 6 to the floor 8 and for preventing the floor 8 from buckling. Reference numeral 10 denotes an outer plate such as a bottom plate of the ship.

[0004]

[Problems to be solved by the device]

 By the way, in the conventional aggregate structure of a ship as described above, since many upper and lower ends 9a and 9b of the stiffeners 9 attached to the floor 8 need to be welded to the longe 6 and the like in an abutting state, There is a problem in that it takes a lot of time for the welding work because it is necessary to accurately weld the corners.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned conventional problems, and the longitudinal and girder extending in the front-rear direction of the hull and the floor extending in the lateral direction are crossed to each other to make the floor. A plurality of stiffeners extending in the vertical direction are arranged on the side surface of the stiffener, and both ends of the stiffener are used as snip ends to provide an aggregate structure for a ship configured to have a gap with other members. is there.

[0006]

[Work]

 In the aggregate structure of a ship with the above structure, the longitudinal and girder are used for bending the hull in the front-back direction, and the floor is used as a strength member for lateral bending, and as a reinforcing material for the floor itself. The stiffener works. In other words, the force applied to the longe is transmitted to the floor only by the shearing force between the web of the longe and the floor.

【Example】

 1 to 3 show a first embodiment, and FIGS. 4 and 5 show a second embodiment. Based on these drawings, an embodiment of an aggregate structure in a ship according to the present invention is shown. explain. 1 is a side sectional view of a main part, FIG. 2 is a front view thereof, and FIG. 3 is a perspective view thereof.

Reference numeral 11 denotes an outer plate such as a ship bottom outer plate. On the outer plate 11, a longitudinal 12 extending in the front-rear direction of the hull and a girder (not shown), and a floor extending in the lateral direction. 14 are welded respectively. A large number of stiffeners 15 are welded to one side (or both sides) of the floor 14 on the side surface of the floor 14. Both ends 15a, 15b of the stiffener 15 are formed as "snipping ends" having end faces inclined outward, and the upper and lower ends are separated by a space d between the outer plate 11 and the double structure inner plate 16. It is formed to the dimensions that it has.

FIG. 4 is a second embodiment showing a modification of the aggregate structure of FIG. 1, in which stiffeners 15 are arranged on both sides of the floor 14. Also in this case, both ends 15a and 15b of the stiffener 15 are formed at the snip ends, and a gap d is formed between the both ends and the long 12 to facilitate welding. FIG. 5 is a front view according to the third embodiment. In this embodiment, two long stiffeners 15 are arranged on both sides of a longe 12, and both ends 15a and 15b of the stiffener 15 are It is formed at the snip end, and a space d is formed between the bottom shell plate 11 and the double structure inner plate 16.

It should be noted that, although the drawing shows the embodiment in the double structure part, the single structure can also be applied within a range in which the effect of the present invention can be obtained. In the present invention, since the force applied to the longe 12 is transmitted to the floor 14 only by the shearing force between the longe 12, the web and the floor 14, the plate thickness of the floor 14 at this portion must be sufficient. In addition, stiffeners 15 with snips formed at both ends are arranged to prevent buckling of the floor 14, but between the both ends 15a, 15b of the stiffener 15, the bottom outer plate 11 and the double structure inner plate 16. It is necessary to form a space d. In addition, in each of the above examples, the case of the double structure is shown, but the case of the single structure can be similarly carried out.

[0011]

[Effect of the device]

 An aggregate structure of a ship according to the present invention has a longitudinal section 12 and a girder extending in the front-rear direction of the hull 1 and a floor 14 extending in the lateral direction, and extends in the vertical direction of the side surface of the floor 14. A plurality of stiffeners 15 are arranged, and both ends 15a and 15b of the stiffener 15 are used as snip ends, and a gap d is provided between the stiffeners 15 and the other members 12, 16 and 11 approaching the both ends 15a and 15b. It is configured as follows.

With the above-described structure, the upper and lower ends 15a and 15b of the plurality of stiffeners 15 arranged on the side surface of the floor 14 are provided with a space d between the other members 12, 16 and 11. Since the joint length is reduced, the welding work is reduced, and it is easy to maintain the precision during three-dimensionalization because there is no joint. As a result, the work period can be shortened, and the mechanization and automation of the robot etc. can be promoted by completing the work on the flat panel.
