The protective wall for the stray bullet and firing noise cut off

摘要

The present invention relates to a firewall for blocking grenade and shooting noise, and more specifically, a grenade, assault bomb, and misfired bullet (hereinafter collectively referred to as 'grenade') that may fly from a live bullet shooting range to a nearby road or private house and injure human life. .) to prevent human casualties, easy to install, easy to manage and maintain, and grenade and shooting noise that can block external gaze for soundproofing of shooting noise, protecting major facilities, and improving the concentration of the shooter It relates to a barrier barrier. The protection wall (1) for blocking grenade and shooting noise according to the present invention is a protection wall for blocking grenade and shooting noise at a shooting range at a predetermined interval along a straight or curved installation line (not shown) formed on a retaining wall or a concrete block. H-beam frame 100 coupled and fixed by anchor bolts (not shown) on the installed base plate; It is formed in a rectangular shape formed by hot (hot press) or a cold method of natural hardening by mixing waste tire chips with a binder, and the web (web, 104) and web (web, 104) spaced apart from the adjacent H-beam frame 100, and the projectile rubber block 200 inserted and placed in the groove portion 103 between the upper flange 101 and the lower flange 102; It is formed of rectangular-shaped natural rubber or synthetic rubber and is attached to the front and rear surfaces of the H-beam frame 100 with the H-beam frame 100 placed in the center, and a spaced portion between adjacent projectile rubber plates 300 is placed at a predetermined distance between the projectiles. And the rubber block 200 and the projectile rubber plate 300 is coupled to each other alternately; It is formed to have a length that does not deviate from the sum of the thickness of the projectile rubber plate 300, the thickness of the upper flange 101 of the H-beam frame 100, and the thickness of the projectile rubber block 200, and the projectile rubber plate 300 and a direct coupling piece 400 for coupling and fixing to the projectile rubber block 200 inserted and placed in the groove portion 103 of the H beam frame 100; and the projectile rubber block 200 and the projectile rubber plate The particle size of the waste tire chip forming 300 is, when firing a live bullet, the sound of a gun shot first hits the bullet rubber plate 300 with small rubber particles, and then the sound is blocked, and then the bullet rubber block 200 with thick rubber particles inside. In addition, when a ricochet or a grenade occurs, it is decelerated while passing through the rubber bullet plate 300 with small particles, and secondly, it is lodged in the bullet rubber block 200 with large particles, and the Even when penetrating the projectile rubber block 200, the rear particles are blocked by the small projectile rubber plate 300 once again, thereby preventing the risk of human damage due to the projectile projectiles being shot, and included in the waste warhead. In order to prevent environmental pollution such as soil contamination by the lead (Pb) component and water pollution caused thereby, the particle size of the waste tire chips forming the bullet rubber plate 300 of the front and rear surfaces is determined by the bullet rubber block ( 200) is characterized in that it is formed smaller than the particle size of the waste tire chips forming the. In addition, the bullet-proof rubber block 200 of the protective wall 1 for blocking the grenade and shooting noise of the present invention is characterized in that a bullet-proof iron plate 210 made of high wear steel is inserted therein. According to the present invention, the protection wall (1) for blocking grenade and shooting noise, which is configured as described above, blocks grenades, robbers, and misfires flying into a road or a private house near a shooting range to prevent damage to human life, as well as easy installation It is easy to manage and maintain, and for soundproofing of shooting noise, protecting major facilities, and improving the concentration of the shooter, a protective wall for blocking grenade and shooting noise that can block external gaze while having a beautiful appearance will be provided.
