Abstract

(57) [Summary] [Purpose] To provide a hull structure capable of eliminating stress concentration, which is a problem at a joint between a reinforcing member and a longe, and reducing the number of welding steps. In a hull structure in which a trans-web 6 and a longe 7 loosely fitted in a slot 91 'opened in the trans-web are joined to a plate member 8, a lower edge 71a of the longe is replaced by a lower edge of the slot. It was bonded to 91'a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hull structure, and more particularly to a hull structure in which a longe is penetrated through a transweb and attached to a plate material.

[0002]

[Prior art]

 As a plate material for an oil carrier or a cargo ship, a bottom plate 1 as shown in Fig. 2, a ship side plate 2, a bulkhead 3 or a bottom plate 4 of a top side tank as shown in Fig. 3 and a double bottom top plate 5 are used. Etc. Conventionally, the trans-web 6 and the longe 7 are joined to these plate materials, and the color plate as the reinforcing member and the reinforcing member with the lateral member are joined to these to form a hull structure.

FIG. 4 is an enlarged view of a portion A of FIGS. 2 and 3. A transweb 6 is joined to a plate material 8 such as a ship bottom outer plate so as to stand upright from the plate material 8. Further, a slot 9 for inserting the longe 7 is opened in the trans-wave 6 in a U shape, but this slot 9 has an L-shaped cross section of the longe 7 for facilitating the insertion of the longe 7. The opening is considerably larger than the shape. The longes 7 pass through the slots 9 and are loosely fitted to the trans web 6 and joined so as to intersect. Although a part of the longe 7 is directly joined to the transweb 6, the bonding strength between the two 7 and 6 is often not sufficient by itself, and the collar plate 10 and the lateral member as a reinforcing member to compensate for it are often present. Reinforcement material 11 is hung and bonded between the longitudinal 7 and the trans web 6, respectively.

However, stress is likely to be concentrated on the joint portion B between the reinforcing member 11 and the longe 7, and damage is likely to occur. Further, by providing the reinforcing material 11, there is a problem that the number of man-hours for welding work increases, and the work period becomes longer accordingly.

[0005]

The present invention has been made in order to overcome such a drawback in the future, and its purpose is to eliminate stress concentration which is a problem at a joint between a reinforcing member and a longe and to perform welding. It is to provide a hull structure that can reduce man-hours.

[0006]

[Means for Solving the Problems]

 The hull structure of the present invention that can achieve the above object is a hull structure in which a trans-web and a longe that is loosely fitted in a slot opened in the trans-web are joined to a plate material. The feature is that the lower edge is joined to the lower edge of the slot.

In the hull structure in which the trans-web and the longe which is loosely fitted and arranged in the slot opened in the trans-web are joined to the plate material in this way, the lower edge of the longe is set to the lower edge of the slot. By joining, the reinforcing material becomes unnecessary, so that stress concentration which is a problem at the joining portion between the reinforcing material and the longe can be eliminated. In addition, it also reduces the weight. Furthermore, the man-hours for welding are reduced, and the work period can be shortened.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 6 is a transweb, 7 is a longe having a T-shaped cross-section, 8 is a plate material such as a ship bottom outer plate, and the plate material 8 has a transweb 6 and a T-shaped slot opened in the transweb 6. It is joined with the longe 7 which is loosely fitted and arranged in 91.

In the present invention, the head 91 ′ of the T-shaped slot 91 has a mushroom shape, and its lower edge 91 ′ a is welded to the lower edge 71 a of the head 71 of the T-shaped cross section. It is joined by. Further, the body 72 of the longe 7 and the slit-shaped body 91'b of the slot 91 are joined by welding. Further, the longes 7 and the plate member 8 are joined by welding. Reference numeral 92 is a semicircular slot provided in the transweb 6.

As described above, since the lower edge 71a of the head 71 of the T-shaped cross section 7 and the lower edge 91'a of the head 91 'of the mashroom-shaped slot 91 are joined by welding. The shearing area for transferring the load from the cylinder 7 to the transweb 6 increases. The increased joining area eliminates the need for conventional reinforcements. Then, the number of welding steps can be reduced and simplified. It also reduces the weight. Furthermore, stress concentration, which has been a problem at the joint between the reinforcing member and the longe 7, is eliminated.

The head 91 ′ of the slot 91 is not limited to the mushroom shape, and the underline of the longi head and the lower edge of the slot can be welded to each other, for example, oval or semicircular. Anything will do.

[0012]

[Effect of device]

 As described above, the present invention provides a hull structure in which a trans-web and a longe that is loosely fitted in a slot opened in the trans-web are joined to a plate material. Since it was joined to the lower edge, it became possible to eliminate the problem of stress concentration at the joint between the reinforcing material and the longe. Furthermore, the number of welding steps can be reduced and simplified. Also, the weight can be reduced.
