The working principle is as follows: when the indoor explosion pressure is close to the explosion venting pressure of the explosion venting bolt, the explosion venting bolt does not have a fixed acting force on the second light plate any more, the second light plate can fly outwards due to the impact force generated by explosion, the first pressure relief opening is formed in the second gap, the shock wave formed by explosion can be quickly released outwards through the pressure relief opening, the first light plate can fly outwards through the explosion venting roof surface, the second pressure relief opening is formed in the first gap, the shock wave can be further released outwards, the damage influence of the explosion destructive force on an indoor structure and properties can be reduced to the minimum by carrying out two times of explosion venting, meanwhile, due to the constraint effect of the traction guy, the first light plate and the second light plate which fly in an explosion manner cannot fly away from a building under the effect of the explosion pressure, and the damage of surrounding properties and people due to the board which flies is avoided.
Further, the first gap and the second gap are arranged in a crossed mode.
Further, the diameter of the first gap is 5-10 cm.
Further, the diameter of the second gap is 10-20 cm.
Furthermore, the first light plate bottom wall and the metal plate top wall corresponding to the first light plate bottom wall are both fixed with fixing pieces, and a traction cable is fixedly connected with the fixing pieces.
Furthermore, the top wall of the second lightweight board and the bottom wall of the explosion venting roof corresponding to the top wall of the second lightweight board are both fixed with fixing pieces, and a traction cable is fixedly connected with the fixing pieces.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses an it has first space to open at the roof face equidistance of exploding to let out, it has the second space to open at the metal sheet equidistance of the roof face lower extreme of exploding to fix to let out, first space and second space cross arrangement, all be fixed with first light board and second light board respectively through letting out the bolt on first space and the second space roof, when indoor explosion pressure is close to the pressure of exploding of letting out the bolt, fly to form first pressure release mouth with the second light board to the outer bullet of second light board earlier, fly to form the second pressure release mouth when letting out the roof face through letting out again, carry out twice and let out and explode and can make the destruction influence of explosion destructive power to indoor structure and property and fall to minimumly.
2. The utility model discloses a pull the cable and fix first lightweight board on the metal sheet respectively, fix the second lightweight board on letting out the explosion roof, the first lightweight board that the bullet flies and the second lightweight board can not fly away from the building under the effect of explosion pressure during the explosion, avoid around property and people to cause the harm because of the panel that the bullet flies.
