The specific embodiment

Specify specific embodiment of the present invention below in conjunction with accompanying drawing.

The object of the present invention is to provide a kind of ought indoorly blasting can effectively resist explosion tension force and fire-proof and explosion-proof wall, it is fire-retardant that this Explosion proof stopping can effectively be resisted outside tension force and consequent flame that the blasting impact ripple causes.The agent structure of fire-proof and explosion-proof wall of the present invention is made up of bursting diaphragm, PLASTIC LAMINATED, keel and filler.This bursting diaphragm is arranged at outermost layer, and its material has high impact properties, can provide splendid anti-high-pressure spray to penetrate impact force.The adjacent bursting diaphragm setting of this PLASTIC LAMINATED is positioned at the nexine of body of wall, and its chemical composition can be effectively fire-retardant, reaches the fireproof purpose.These keel constitute the main body frame of body of wall, and the shape that has adopted cross section to be " ㄇ " shape is filled the post of, between PLASTIC LAMINATED, as the fixed structure of whole body of wall.Filler is arranged in the inner space that is made up of shape of " ㄇ " shape and nexine PLASTIC LAMINATED, has the function of heat preservation and soundproof, and can add chemistry sun combustion composition.

When indoor blasting, can be divided into physical property blast, chemical blast and dust explosion according to explosion cause.The physical property blast is that container can't bear load and breaks because container internal pressure is too high, and the phenomenon of the rapid release of pressure that takes place.The chemical blast, like oil, gunpowder class material, because its exothermic reaction apace, the pressure that is caused increases sharply and discharges.Dust explosion is meant that dust mixes then with air, and flame propagation is very quick, and almost moment is owing to the pressure that the gas expansion is produced is blasted.Above-mentioned blast all can be divided into three different blast classes, and the stage of promptly detonating, pressure discharge stage and combustion phases.

Fire-proof and explosion-proof wall provided by the present invention can play the effect of security protection in three different phases of blast.The moment that blast takes place, shock wave is maximum to human body or the damage that property caused on every side, can cause the generation of superpressure, and blast simultaneously makes the fragment of the high-speed flight that is produced also can cause huge damage to human body.Therefore the present invention utilizes bursting diaphragm to intercept the shock wave that moment produced of blast, provides anti-high-pressure spray to penetrate impact force.

When blast gets into pressure release stage and combustion phases, the high heat that explosion center point produces, temperature is up to more than thousand degree.Therefore in the isolated shock wave of bursting diaphragm, PLASTIC LAMINATED can be effectively fire-retardant, and the filler at body of wall center can play isolated high temperature, the technique effect of protection human body.

Specify specific embodiment of the present invention below in conjunction with accompanying drawing.Fig. 1 is a perspective view of the present invention.Wherein, fire-proof and explosion-proof wall provided by the present invention is made up of four parts, bursting diaphragm 1, PLASTIC LAMINATED 2, keel 3 and filler 4.As shown in Figure 1, bursting diaphragm 1 is the outermost layer in whole wall body structure, has high impact properties for making its material, and bursting diaphragm 1 adopts sandwiched type structure, promptly adopts sandwich type structural.As shown in Figure 2, bursting diaphragm 1 comprises that top layer 1b and interlayer 1a form.Its mesexine is the metal construction of strong shock resistance.Preferably, in the present embodiment, adopt hot-dip galvanized steel sheet as top layer 1b.Hot-dip galvanized steel sheet has antiseptic and rustproof characteristic, and therefore no matter the present invention is applicable to can both have been given play to the preferred technique effect under which kind of environment.Interlayer 1a has adopted the reinforcing fiber cement that does not contain asbestos.In the present embodiment, its thickness of the hot-dip galvanized steel sheet of top layer 1b is 0.5mm, and the thickness that the reinforcing fiber cement that does not contain asbestos of interlayer 1a is selected for use is 10mm.In actual application, can select suitable thickness according to the difference of applied environment.
