[ Therefore, at the rear of the explosion-proof wall 100 according to the present invention, the energy of explosion is transmitted or minimized to a very small amount even when the explosion energy is transmitted. Therefore, the explosion-proof wall 100 ) Is in a safe position against the explosion.

In the explosion-proof wall body 100 of the present invention, since the bulletproof panel 24 is provided in the bullet-proof and explosion-proof panel unit 2, explosion occurs in front of the front panel 1 and the fragments of the explosive are scattered backward, The bullet is fired from the front of the plate 1 and the explosive debris or the bullet can not be passed through the bulletproof plate 24 even though the bullet passes through the front plate 1. Therefore, 100) is also in a safe position against penetration of bullets or explosive fragments.
