Description
Technical field
The utility model is related to a kind of flexible arrangement of the inclined muscle of ship car ramp, belongs to ship car ramp structure skill
Art field.
Background technology
Roll-on-roll-off ship oceangoing ship often needs to set substantial amounts of each layer deck of connection because needing the need for meeting each layer deck of vehicle pass-through
Car ramp.Fixed ramp is small because building difficulty, and cost is low, is favored by shipyard and shipowner.Hung down on traditional ramp longitudinal bulkhead
Straight reinforcement typically uses alignment with deck deck transverse, and is connected by bracket.According to real shipping battalion feedback in connection elbow
Crackle is often also easy to produce at plate, the maintenance cost for runing ship is huge, and certain economic loss is caused on shipowner and ship is influenceed just
Often operation, as shown in Figure 1.
Roll-on-roll-off ship oceangoing ship often needs to set substantial amounts of each layer deck of connection because needing the need for meeting each layer deck of vehicle pass-through
Car ramp.Ramp is generally divided into mov-ing ramp and fixed ramp, and mov-ing ramp is roll-on/roll-off facilities, and cost is high, supporting
Structural strengthening is complicated；Fixed ramp is a part for Ship Structure, builds difficulty and cost is low, blueer or green by shipyard and shipowner
Look at.The fixed pits rampway structure arrangement of traditional form is as shown in Figure 2,3.
Vertical stiffeners typically use alignment with deck deck transverse on traditional ramp longitudinal bulkhead, and are connected by bracket
Connect.Roll-on-roll-off ship height is high, deformation is subject to deflection during ship rolling, the transverse strength of such ship is particularly important.Due to solid
Fixed pattern ramp opening have impact on deck deck transverse continuity, and big in deck cross member and longitudinal bulkhead intersection moment of flexure, stress concentration is existing
As obvious.Crackle is often also easy to produce at connection bracket according to real shipping battalion feedback, as shown in the position 1 in Fig. 3.
To solve problem above, the vertical stiffener of original flat-bulb steel is is changed to stronger T profile by current Normal practice, such as
Shown in Fig. 4.Though can relieving fatigue crack problem, be due to that T profile web height is big, influence to a certain extent vehicle pass-through and
Track area, certain economic loss is brought to shipowner.
The content of the invention
The purpose of this utility model is to provide a kind of flexible arrangement of the inclined muscle of ship car ramp, it is to avoid produced at bracket
Fatigue crack；Avoid influenceing track area during stiffener vertical using T profile simultaneously, wagon loading is reduced, so as to avoid to shipowner
Bring economic loss.
The utility model uses following technical scheme：
Some vertical deepbars 2 are fixedly installed on a kind of flexible arrangement of the inclined muscle of ship car ramp, side plate 1,
Vertical deepbar 2 is fixedly connected by horizontal band steel 4 with longitudinal bar steel 3, is staggered in longitudinal bar steel 3 with the position of band steel 4
Position on be fixedly connected with some horizontal deck beams 5.
Further, vertical deepbar 2 is formed by two pieces of steel plate vertical weldings.
Further, the horizontal deck beam 5 is formed by two pieces of steel plate vertical weldings.
Further, the horizontal deck beam 5 and the connecting portion of longitudinal bar steel 3 are located at the interposition at adjacent band steel position
Put.
Further, the spacing between adjacent horizontal deck beam 5 is equal.
The beneficial effects of the utility model are：
1) without using bracket, while it also avoid the situation of bracket fatigue cracking；
2) avoid influenceing track area during stiffener vertical using T profile, add wagon loading, improve ship loading
Economic benefit.
3) roll-on-roll-off ship flexible design theory, the i.e. vertical deepbar of crossbeam, topside are realized, pillar etc. forms a kind of dislocation arrangement
Flexible, hinged structure, only transmit vertical force without transmitting moment of flexure in tyrannical beam end, resist horizontal by the deformation of flexible structure
Xiang Li.
4) the problem of being directed to current ramp attachment structure, proposes to cancel vertical stiffener under crossbeam and bracket, deck is strong
Beam-end is cut tiltedly, and the ramp flexible structure cloth of muscle partially is cut tiltedly at increase two ends at the rib position of ramp longitudinal bulkhead crossbeam both sides 1/2
Put, it is ingenious in design.
5) physical dimension is not being increased, in the case of track area and vehicle pass-through are not influenceed, reduction deck cross member and slope
Road longitudinal bulkhead junction produces the risk of fatigue crack, reduces the maintenance cost during operation.

Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 6-Figure 10, a kind of inclined muscle of ship car ramp flexible arrangement is fixedly installed some on side plate 1
Vertical deepbar 2, vertical deepbar 2 is fixedly connected by horizontal band steel 4 with longitudinal direction bar steel 3, in longitudinal bar steel 3 with it is flat
Some horizontal deck beams 5 are fixedly connected with the position that the position of steel 4 is staggered.
Referring to Fig. 7, vertical deepbar 2 is formed by two pieces of steel plate vertical weldings.
Referring to Fig. 7, the horizontal deck beam 5 is formed by two pieces of steel plate vertical weldings.
Referring to Fig. 6-7, the connecting portion of the horizontal deck beam 5 and longitudinal bar steel 3 is located at the centre at adjacent band steel position
Position.
Referring to Fig. 6-7, the spacing between adjacent horizontal deck beam 5 is equal.
Roll-on-roll-off ship rigid design theory is the horizontal strong component such as deck transverse of hull, the vertical deepbar of topside, the shape such as pillar
Into the structure of closure, cross force is resisted by cross member itself, as shown in Figure 5.Roll-on-roll-off ship flexible design theory such as Fig. 6,7 institutes
Show, i.e. the vertical deepbar of crossbeam, topside, a kind of flexible, hinged structure for the arrangement that misplaces of the formation such as pillar, in tyrannical beam end only
Vertical force is transmitted without transmitting moment of flexure, cross force is resisted by the deformation of flexible structure.The maximum of rigidity and flexible design theory
Difference is whether horizontal strong component forms closed loop configuration, and rigid design cross member formation closed loop configuration, flexible design is horizontal
Component formation misconstruction.
