Description
Technical field
A kind of ship side composite sandwich plate structure of the present invention, more particularly to a kind of composite intermediate layer for being arranged on ship topside
Hardened structure, it is this that there is composite sandwich plate structure ship topside only to occur in less neighboring area in ship topside collision rift
Plastic deformation destruction.
Background technology
The collision that ship occurs in high speed operation has the features such as striking momentum is big, kinetic energy is big, process time is short.This
When, traditional anticollision device, collision-prevention device can only absorb very small part impact energy, and most energy are by the less collided ship topside of rigidity
Structure absorbs, and causes the local failure of collided ship oceangoing ship topside or even occurs damage so that crude oil, the hazardous chemical of ship loading
Deng leaking, severe contamination navigation channel waters and surrounding environment even result in the sinking of collided ship oceangoing ship when serious.Therefore, in hull
Especially strengthen the crashworthiness structure of ship topside in structure, existing crashworthiness structure be mainly focused on how to strengthen local stiffness and
Increase topically effective energy-absorbing unit, also increase hull weight while increase local crash-worthiness, influence ship overall performance.
The content of the invention
The present invention overcomes the deficiencies in the prior art, and technical problem to be solved is：A kind of new topside is provided
Structure, meets and lowers hull weight requirement.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of ship side composite sandwich plate knot
Structure, including：Inorganic foamed core, steel plate keel layer, foaming aluminium lamination, anticorrosive coat and skin of paint；
The both sides of the inorganic foamed core be disposed with from inside to outside inorganic foamed core, steel plate keel layer, foaming aluminium lamination,
Anticorrosive coat and skin of paint, the inorganic foamed core are internally provided with multiple hollow holes；The hollow hole is vertically set
Put.
The foaming aluminium lamination is sandwich construction.
The thickness of the foaming aluminium lamination is 10mm ~ 20mm.
The hollow hole is square opening.
The yield strength of the steel plate keel layer is not less than 600Mpa.
The present invention has an advantageous effect in that compared with prior art：Longitudinal direction is laid in the composite sandwich plate of the present invention to pass through
The foaming aluminium lamination worn, when ship topside collides by shock loading, can effectively prevent the breakage of local side plate, so that
The larger locality destruction of substitution is destroyed with less globality, damage occurrence probability is reduced, improves collided ship survival rate, it is excellent
Ship topside itself energy-absorbing form is changed, has reduced ship topside mortality local failure and ensure ship overall performance again simultaneously.
Brief description of the drawings
The present invention will be further described in detail below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of inorganic foamed core in the present invention；
In figure：1 it is inorganic foamed core, 2 be steel plate keel layer, 3 be foaming aluminium lamination, 4 be anticorrosive coat, 5 be skin of paint, 6 is empty
Heart hole.
Embodiment
As depicted in figs. 1 and 2, a kind of ship side composite sandwich plate structure of the invention, including：Inorganic foamed core 1, steel
Board keel layer 2, foaming aluminium lamination 3, anticorrosive coat 4 and skin of paint 5；
The both sides of the inorganic foamed core 1 are disposed with inorganic foamed core 1, steel plate keel layer 2, foaming aluminum from inside to outside
Layer 3, anticorrosive coat 4 and skin of paint 5, the inorganic foamed core 1 are internally provided with multiple hollow holes 6；The hollow hole 6 is along perpendicular
Nogata is to setting.
The foaming aluminium lamination 3 is sandwich construction, and the thickness of the foaming aluminium lamination 3 is 10mm ~ 20mm.
The hollow hole 6 can be used in square opening or circular port, present embodiment using the side that cost is relatively low
Shape hole；
The yield strength of the steel plate keel layer 2 is not less than 600Mpa.
The inorganic foamed core 1 can use by binder materials, CBA, polypropylene fibre, glass bead and
Generated after the uniform stirrings such as perlite by chemical foaming technology, a large amount of hollow holes, Neng Gou great are contained in the inorganic foamed inside of core 1
It is big to lower topside weight.
The foaming aluminum that the foaming aluminium lamination 3 is used is kind of a very light metal, and aluminium ingot is melted, after foaming process,
It is 0.2 foaming aluminum with countless stomatas to form proportion, and only just 1/40 is compared with the proportion of iron 7.85；So this is for full
Sufficient steamer etc. is more than sufficient using the requirement of lightweight material.Foaming aluminum also has other remarkable properties in addition to lightweight：First,
Because foaming aluminum possesses many air hole structures, so with noise and shock proof performance is absorbed, being additionally, since foaming aluminum is
Sandwich construction, so extraneous blast can be fully absorbed, the shock resistance of the energy such as resistance.
The present invention composite sandwich plate in laid longitudinally through foaming aluminium lamination, rushed when ship topside collides
When hitting load, the breakage of local side plate can be effectively prevented, is broken so as to destroy the larger locality of substitution with less globality
It is bad, damage occurrence probability is reduced, collided ship survival rate is improved, ship topside itself energy-absorbing form is optimized, the ship side of a ship is reduced
Side mortality local failure ensures ship overall performance again simultaneously.
In addition to the implementation, the present invention can also have other embodiment, all use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
