Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
embodiment 1
As shown in Figure 1, 2, the platform bulkhead structure of a kind of antiknock, fire prevention, insulation, noise reduction, comprise the sandwich plate and a shock resistance structure that be arranged in parallel for about a pair, described shock resistance structure comprises the upper lower trapezoid group be made up of three leaf springs 5 respectively, damping material 6 is provided with between upper lower trapezoid group, connected by damping spring 7 between adjacent upper lower trapezoid group, upper lower trapezoid group inside is filled with the first weighting material 8; Sandwich plate comprises the skin panel up and down 2 of pair of parallel setting, and skin panel 2 outside face scribbles insulating barrier 1, accompanies battenboard 3 between two pieces of skin panels, is filled with the second weighting material 4 between battenboard 3 and skin panel 2 gap.
In order to the decibel and the heat-insulation and heat-preservation that make bulkhead reduce noise in routine use, and in shock wave, play crucial protective action, improve the energy-absorbing of structure, reduce bulkhead corrosion, radiation-inhibiting, insulate further, and the first weighting material 8 is isocyanurate foam; Second weighting material 4 is thermoplastic polyimide foam.
In order to make the loading strength shock wave of diabolo formula shock resistance structure play buffer action, reduce the deflection of fluctuate interlayer plate, improve shock environment, leaf spring 5 is damping plate spring.
As shown in Figure 3, battenboard 3 is zincing steel sheet, and its longitudinal cross-section is C shape, and make the loading strength shock wave of battenboard play buffer action, in minimizing, the deflection of skin panel structure, improves shock environment.
Two-layer skin panel 2 is zincing steel sheet, and its thickness is 2mm.
In order to make bulkhead inner circuit system by shock wave destroy cause electric leakage after, good insulation effect can be played in the case of a high temperature, block current flowing, avoid electrical fire, insulating barrier 1 is high-temperature insulation ceramic coating, and its thickness is 2mm.
In order to make the loading strength shock wave of diabolo formula shock resistance structure play buffer action, in minimizing, the deflection of lower trapezoid group, improves shock environment, and damping material 6 is foam silicone rubber, and its thickness is 5mm.
The height of battenboard 3 is 20mm, and wall thickness is 2mm.
The height of diabolo formula shock resistance structure is 35mm.

embodiment 9
As shown in Figure 10, in the present embodiment, the longitudinal cross-section of battenboard 3 is circular.Other are with embodiment 1.
In above-described embodiment, battenboard 3 thickness can require to design according to cushion characteristic.Bulkhead structure is formed by welding or glueing joint by layer sandwich structure and upper and lower covering, and divide between covering and laminboard layer in manufacturing process and put into weld layer or adhering film, then high-temperature heating makes it bond.The High molecular material core thermoplastic polyimide foam with steel surface contact is filled between two-layered steel plates, be adhered between I type and skin panel to Polyimide foams elastic body high strength, for steel plate provides the support of continuous uniform, greatly improve the anti-local bending performance of steel plate.
In the ordinary course of things, rigidity of the present invention can ensure normal use, can play good noise reduction by isocyanurate foam and thermoplastic polyimide foam.When some accidental explosions occurring and causing fire, carry out energy-absorbing by sacrifice laminboard layer and weighting material.Polyurethane is elastomeric material, can realize transmission and the dispersion of the shearing force between core and leaf spring, even if when bearing arch or sagging load, leaf spring and core layer also can integrally bending deformations, there will not be local bending and causes the distortion of sandwich plate.Therefore, diabolo formula shock resistance structure integrally can be born much larger than load-carrying capacity during clean steel plate.Because the resiliency of battenboard and packed layer is much larger than the resiliency of skin panel, the buffering of successively being carried out in various degree by I template and thermoplastic polyimide foam is out of shape, Transmit evenly shearing force, in adjacent structure, avoids the structural support of a large amount of dispersion.Good insulation effect is played by high-temperature insulation ceramic coating.By thermoplastic polyimide foam fireproof.Thus protection platform blocks fire spreading.At utmost reduce the harm that blast produces, the platform bulkhead structure of the antiknock of all embodiments, fire prevention, insulation, noise reduction is by 20kg explosive charge, and the quick-fried test carrying out antiknock ability under operating mode of 3.5m, all can reach energy-absorbing more than 89.7%.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from technological thought of the present invention, can carry out various change and amendment completely.Technical scope of the present invention is not limited to the content on specification sheets, must determine its technical scope according to right.
