The girder construction of the car deck of car carrying ship
Technical field
The present invention relates to the girder construction of the car deck on the car carrying ship.
Background technology
The car carrying ship is provided with the car deck of multilayer, is loading many automobiles on each layer car deck, and in the carrying vessel that has, can load about 10,000 left and right sides automobiles altogether, so car deck bears bigger load.
The structure of car deck is with on the fixing longitudinal and cross beam that is disposed belowdecks of iron plate.On the transversal surface of cabin, this longitudinal and cross beam by the shipboard member (for example, longeron, reinforced rib etc.) of supporting side plate and the pillar supporting that erectly is provided with belowdecks.
Disclose at Japanese Patent and to have proposed a kind of vehicle delivery hull construction in the clear 54-25089 communique, in this structure, when ad hoc beam or crossbeam are set, at shipboard additional beam is set, and above-mentioned ad hoc beam and crossbeam are installed on this additional beam, and described additional beam is fixed by supporting plate on the shipboard support.
But,, therefore, under the situation of large-scale car carrying ship, when the distance between two relative shipboard limits is big, cause its overall load ability to reduce owing to only come support deck in this technical scheme with various beams such as ad hoc beam, crossbeam, additional beams.
Fig. 6 schematically is illustrated in the beam structure example of the car deck that has 2 pillars on the transversal surface.In this example, the longeron of car deck 2 (shown in sketch in be along extending with the vertical direction of paper) and crossbeam 4 direct respectively be connected with shipboard member 5 and pillar 1 (rigid construction is connected).
But many pillars 1 are set can have restriction to the trafficability characteristic of vehicle on car deck 2, and the shipped quantity of vehicle is reduced.
For this reason, a kind of scheme has been proposed, promptly as shown in Figure 7, on transversal surface, only the structure of 1 pillar is set on the spot in central straight.Under this occasion, the longitudinal and cross beam 4 of car deck 2 also with shipboard member 5 and pillar 1 direct connection.Promptly, which all carries out the bonded assembly structure with rigid construction with respect to shipboard member 5 and pillar 1 in the formation longitudinal and cross beam 4.
On the one hand, when hull was in the wave, car deck 2 on the car carrying ship and crossbeam 4 must absorb the stress that is produced when transverse shape causes angular deformation (crimp).And on the other hand, must suppress by the amount of flexibility of the car deck 2 that forms of load and crossbeam 4, must guarantee the blank height H of lower floor.
Consider this point, also proposed girder construction scheme as shown in Figure 8.In this girder construction, longeron is to be connected with pillar 1 with rigid construction.And, according to the big drinking water grade of the crimp of hull, the crossbeam 4 of top is made and the not direct coupled structure of pillar 1 and shipboard member 5 (flexible structure is connected).
Fig. 9 represents to constitute near this flexible structure bonded assembly pillar beam layout circle with top view.The top of figure is hull the place ahead.In this example, crossbeam 4b, the 4b that passes through with respect to being clipped in the middle with the cooresponding crossbeam 4a in pillar position with pillar 1, disposing additional longeron 6,6 in the both sides of pillar 1.Be connected with above-mentioned additional longeron 6,6 with the cooresponding crossbeam 4a in pillar position, with pillar 1 direct connection not.
But, when adopting this structure, on point of connection A, the A of cooresponding crossbeam 4a in pillar position and additional longeron 6,6, concentrate bigger stress partially, deep camber can take place unavoidably.For this reason, its result must be provided with 2 pillars 1 in fact as shown in Figure 8 at least.
In Fig. 6~Fig. 9, symbol J and G represent respectively that flexible structure is connected with rigid construction and are connected.

The specific embodiment
Below, with reference to Fig. 1~Fig. 5 embodiments of the invention are described.
In the present embodiment, with the identical part sign same-sign of pre-structure and omit detailed description thereof.
Fig. 1 is a hull cross-sectional view of representing car carrying ship notion used in the embodiment of the invention, Fig. 2 is near the partial top view of configuration of the beam side plate of the above-mentioned carrying vessel of expression, Fig. 3 is near the partial top view of configuration of the beam pillar of the above-mentioned carrying vessel of expression, Fig. 4 is the partial top view of another embodiment of expression, and Fig. 5 is the partial top view of another embodiment of expression.In each top view, the top of paper is the front direction of hull.
With reference to Fig. 1, Fig. 1 is a hull cross-sectional view of representing car carrying ship notion used in the embodiment of the invention earlier.In the girder construction of the car deck 102 of present embodiment, the central portion of (left and right directions) only erectly is provided with 1 pillar 101 belowdecks.On the other hand, the crossbeam 104 of car deck 102 is to be connected with pillar 101 with flexible structure, is connected with shipboard member (member of pillar side plate: for example longeron, reinforced rib etc.) 105 again.
As shown in Figure 2, configuration plane faces toward on shipboard member 105, (shipboard is used) additional longeron 107.Between shipboard member 105 and additional longeron 107 (with crossbeam 104 mutually differently) the additional crossbeam 110 of configuration (shipboard is used).Crossbeam 104 is connected with the above-mentioned additional longeron 107 of additionally configuration, directly is not connected with shipboard member 105.Promptly, crossbeam 104 is to be connected with shipboard member 105 with flexible structure.
In the present embodiment, the position of crossbeam 104 and additional crossbeam 110 is offset (promptly not being on the same transversal surface) mutually, but need not be offset, and is connected also passable at (promptly in same transversal surface) on the same position.
Below, with reference to Fig. 3, on the left and right directions belowdecks, erectly 1 pillar 101 is set, crossbeam 104b, the 104b that passes through in two sides of this pillar 101, with respect to the crossbeam 104a of pillar position and clamp posts, disposing (pillar is used) additional longeron 106,106.Be connected with above-mentioned additional longeron 106,106 respectively at the locational crossbeam 104a of pillar, and be not connected with pillar 101.Promptly, be in the crossbeam 104a of pillar position with respect to pillar 101 formation flexible structures connections.Between main longitudinal grider 103 and additional longeron 106,106 by the pillar position, be in point of connection A, the A of the crossbeam 104a of pillar position and additional longeron 106,106 front and back, disposing laterally additional member 108 (in this figure, amounting to 4).
The crossbeam 104b that is in the locational crossbeam 104a of pillar, clamp posts and passes through, additional longeron 106 and laterally the configuration of additional member 108 etc. all be symmetry on the fore-and-aft direction of hull and the left and right directions respectively, pillar 101 is configured in its center.
Fig. 4 represents the variation of girder construction shown in Figure 3.
Fig. 4 (A) expression pillar 101 the example of position from the off centering between (clamp posts is passed through) crossbeam 104b, the 104b uprightly be set.In this example, be in the locational crossbeam 104a of pillar and be connected with additional longeron 106,106, and with pillar 101 direct connection (flexible structure is connected) not.
And laterally 108 of additional member are configured in the side along the hull fore-and-aft direction (among the figure be side) in the wings of pillar.The example, the horizontal additional member 108 that comprise Fig. 3 also can be in the side configurations a plurality of (shown in dotted lines) of pillar 101.
In Fig. 4 (B), the crossbeam 104b that is in the crossbeam 104a, clamp posts 101 of pillar position and passes through, additional longeron 106, laterally those of configuration and Fig. 3 of additional member 108 etc. are identical, promptly, all are symmetrical on the fore-and-aft direction of hull and left and right directions respectively.But the pillar 101 upright positions that are provided with are but with respect to the center of these members, displacement forwards.
In each variation shown in Figure 4, because the structure of beam all is used for the car carrying ship, so consider from relation such as the effective dimensions of car deck and the layout in the ship, can not will pillar be configured in the interval central authorities of longitudinal and cross beam, be special actv. under this occasion.
Like this, above-mentioned in employing with horizontal additional member 108, when being configured in the structure between the additional longeron 106,106, make and be in the locational crossbeam 104a of pillar and be connected with pillar 101 with flexible structure, on this basis, the part load that acts on point of connection A, the A can support with this horizontal additional member 108, and can obtain is flexible structure, and is the structure that does not have stress raisers.
Owing to also adopt flexible structure at shipboard, thereby the load that is added on crossbeam 104a, the 104b is just born by the shipboard member 105 of flexible structure.Like this, can not take place to connect and the stress raisers of the shipboard portion that causes by near the flexible structure the pillar.
Fig. 5 represents near another embodiment of the girder construction the pillar.
In the embodiment shown in fig. 5, the interior main longitudinal grider that passes through the pillar position 103 (with reference to Fig. 3, Fig. 4) of cabin is not set.
(A) of Fig. 5 is configured in horizontal additional member 112 between the additional longeron 106,106, and disposes (pillar is used) vertically additional member 109 between pillar 101 and horizontal additional member 112, to substitute above-mentioned main longitudinal grider 103 by the pillar position.
Fig. 5 (B) is the structure with respect to (A), further (the 2nd pillar is used) vertical additional member 114 is configured between horizontal additional member 112 and (clamp posts is passed through) crossbeam 104b.
In the embodiment shown in Fig. 5 (A), (B), any one all be with the master by the pillar position in length and breadth the 103 additional longerons 106,106 that are replaced into the configuration of clamp posts 101 ground pass through along the ship length direction.In other words, be to be provided with 2 identical states of (master) longeron with left and right directions, sky in cabin with opening certain intervals, at this moment, we can say that also the flexible structure that longeron forms with respect to pillar connects.
Therefore, when adopting so main longitudinal grider 103 abridged structures that obstinately will be by the pillar position because can also be by this structure, realize the flexible structure (particularly because can allow to a certain extent add longeron 106 carry out lateral deformation or displacement) around the pillar thereby can to a certain degree relax stress concentration on this part point of connection A, A to a certain extent.Therefore the configuration that can omit above-mentioned horizontal additional member 112 according to the interval of the size of hull, crossbeam.
Fig. 5 (C) represents this example.In this example, form flexible structure at the locational crossbeam 104a of pillar and connect, but horizontal additional member is not set.Pillar is not to be configured between pillar 101 and the horizontal additional member with vertical additional member 120, but is configured between pillar and (passing through to clamp posts) crossbeam 104b.
Like this, can be according to different situations, or as required, dispose horizontal additional member, vertical additional member with various forms.
Excellent results of the present invention:
Because the present invention is in the girder construction on the car deck of car carrying ship, with flexible structure, with crossbeam with pillar, also be connected with the framing member that supports side plate, thereby can be flexibly corresponding with the crimp of hull.When particularly crossbeam being connected with pillar with flexible structure, around pillar, be easy to generate local stress concentration, but in the present invention, owing to added the horizontal additional member that pillar is used, perhaps will alternatively dispose vertical additional member by the main longitudinal grider of pillar, avoid the problems referred to above by this structure, thereby load (is for example disperseed suitably, even make 1 corbeling), can fully bear the crimp of hull, and, owing to can be suppressed to the amount of deflection of crossbeam lessly, thereby can also guarantee the blank height of lower floor.
