The subject of the patent is a GR ballistic block consisting of five walls including two long and two short ones constituting the outer walls and an internal partition wall integ rating the whole structure and forming two gravity channels. Long, short and partition walls were joined with a binder using a polyurethane binder, characterized by high tear resistance, powder gas resistance, temperature, abrasion resistance and chemical resistance. All the walls of the block are made of a ballistic component. The ballistic component constituting the building material of long side walls, short walls and the partition wall of the G R ballistic block is characterized by high physical and mechanical parameters, high tensile strength, high shear modulus, chemical and thermal resistance, high fatigue strength, abrasion resistance, dimensional stability, resistance to chemical agents, gunpowder gas, temperature and tearing caused by bullets fired from side-fire, central ignition and smoothbore, in particular 9mm, 5.56mm and 7.62mm calibers. All of the above parameters significantly increase the life of the ballistic component that the block walls are built with. A sealing apron has been designed for long walls and short walls in their lower inner part, which is a connection between blocks in a ballistic wall structure. The sealing apron is characterized by abrasion resistance, mechanical resistance to the action of powder gases, temperature and has high modulus of elasticity. The apron does not allow the ballistic granules to be blown out of the block through the build-up pressure and momentary channel created by the projectile. The filling of the K2S ballistic block is ballistic granules characterized by high abrasion resistance, high temperature resistance, the effect of powder gases and high mechanical strength. On the long and short walls and the partition wall in the upper and lower part, holes for connecting pins have been made, which allow structural joints of GR ballistic blocks in many variants, which strengthens the connections between the short and long walls of ballistic blocks GR.

Known ballistic blocks constitute a uniform block of vulcanized, glued or pressed rubber granulate through adhesive bonding process. They are made of rubber or rubber compounds, e.g. with polymers. In known solutions for the construction of ballistic walls at shooting ranges, a complete replacement of the element had to be carried out after a very short time of use, e.g. a ballistic block, which involved the dismantling of part of the ballistic wall and its reconstruction. These blocks are not compatible with anti-ricochet blocks and plates. At the same time, full ballistic blocks lose their ballistic properties after being hit by several hundred bullets fired from short or long firearms, often causing so-called ricochets threatening the life or health of people and possibly damaging the property. It should also be noted that the shells that the full ballistic block retain in their interior do not allow them to be reused for recycling. Under the utility model numbers W.127811 and W.128054 whose creators are Jacek Pietrzak and Jerzy Kusmierczyk, ballistic blocks RBB and K2S were used, which during work must be disassembled to supplement the ballistic granules filling the ballistic block and very precisely controlled in relation to the filling of these blocks with ballistic granules (lack of such control results in the complete loss of ballistic properties of the block). Also, through the lack of sealing of joints between ballistic blocks, the momentary channels generated by the bullets inside the block blown ballistic granules outside the block in places where the blocks were joined, which forced them to be constantly filled in with the missing ballistic granules in the structural wall. It is dangerous because the momentary channels created by the projectiles in the K2S and RBB blocks create empty spaces in the blocks and, consequently, the 9mm, 5.56mm and 7.62mm shells find their way through the blocks and can penetrate them through thus endangering people and property if ballistic granules are not replenished. K2S and RBB ballistic blocks require constant control of the amount of ballistic granules in each block, which is very difficult or even impossible when the ballistic wall is a whole structure made of blocks.

GR ballistic block according to the patent is characterized by the fact that two short side walls, two long side walls and a partition wall of GR ballistic block have been merged using a polyurethane binder, characterized by high tear strength, powder gas resistance, temperature resistance, abrasion resistance and chemical resistance, and the block walls are made of a ballistic component characterized by high physical and mechanical parameters, high tensile strength, high module shear elasticity, chemical and thermal resistance, high fatigue strength, abrasion resistance, dimensional stability, resistance to chemical agents, gunpowder gas, temperature and tearing with bullets fired from side-firearms, central ignition and smoothbore, in particular 9mm, 5.56mm and 7.62mm caliber, increased its working span. The parameters of the component allow for temporary deformation of the block wall structure when it is pierced by the projectile and the passage channel is closed, thus preventing ballistic granules from escaping from the inside of the GR ballistic block. Ballistic granules filling the GR ballistic block are characterized by high resistance to abrasion, high temperatures, the action of powder gases and high mechanical strength. This makes it possible to stop projectiles fired from side-fire, central ignition and smoothbore firearms, in particular 9mm, 5.56mm and 7.62mm caliber, inside the GR ballistic block. The ballistic block partition wall integrates the long block walls, strengthening and constructively stabilizing the whole GR ballistic block and dividing it into two gravity channels allowing the free flow of ballistic granules inside the GR block. Thus, each momentary channel created by the projectile in the GR ballistic block in ballistic granules is automatically supplemented gravitationally. Thus, the use of gravitational ducts in the GR ballistic block allows for automatic replenishment of ballistic granules in the ballistic wall structure as well as the use of sealing aprons and pinning of the side walls do not allow even a small amount of ballistic granulate filling that constitutes the key protection, to get outside of the structure. For the long walls and short walls of the GR block on the inside lower part, a sealing apron has been designed, which is resistant to abrasion, high mechanical strength, to powder gases, temperature and has a high modulus of elasticity. The sealing apron closes joints between GR ballistic blocks, thus not allowing the ballistic granules to escape from the inside of the block, at the same time allowing free replenishment of the ballistic granules after the momentary channel is formed by the projectile. In the long and short walls and the partition wall of the GR ballistic block, there are holes in the upper and lower parts for structural pinning, which connect the GR ballistic blocks, reinforcing the places of integration and preventing the movement of long and short walls. The GR ballistic block is subject to further full recycling process because the materials and construction used in it allow the materials to be isolated and used to re-build the GR ballistic block and recover missiles that have been retained by ballistic granules inside the GR ballistic block.

The GR Ballistic Block is a solution useful in building barriers stopping bullets fired from firearms, including building bullet traps at open shooting ranges and in rooms intended for firing firearms. The basic module for the construction of ballistic barriers is a chimney made of GR Ballistic Blocks mounted on top of each other. By incorporating an additional partition wall in the GR block, gravitational channels were created to allow free movement of ballistic granules in the block, which naturally supplements defects in ballistic granules. After the bullet passes through the block wall, the bullet, passing through ballistic granules, creates channels in the uniform structure of ballistic granules. After passing the projectile, these channels are automatically filled with ballistic granules, freely moving under the influence of gravity, thus the structure of ballistic granules is automatically restored, capable of stopping further missiles. Additionally, the projectile, stopping in the granulate, compacts the granulate in the direction of movement, increasing the density of ballistic granules, thereby increasing the properties of the granulate to retain the projectile. The partition wall strengthens and stabilizes the block, and at the same time the entire structure without the need to strengthen it with additional elements. Replacement of worn construction elements, i.e. GR blocks, takes place very quickly, even if the lowest block in the structure is replaced. Supplementing with ballistic granules does not require checking of the amount of material inside the block and any defects are automatically filled up by automatic intake from the top of the structure. The universal structure of GR ballistic blocks enables their vertical positioning, adjacent columnar connection, as well as assembly with an offset. Blocks can also be set with offset and perpendicular displacement, so that the corners of the rooms are covered. The modular structure of the block allows the creation of entire walls and comprehensive construction of entire rooms without the risk of creating empty spaces and pass-through spaces for missiles. Due to the designed structure, gravitational channels in each of the mentioned cases remain unobstructed regardless of whether the assembly of the blocks was carried out adjacent to a column or spacer. Thanks to this, after filling the blocks with ballistic granules, each time it fully fills the inside of the blocks, guaranteeing full and correct functionality despite repeated hits from a firearm.

The GR ballistic block has been designed so that one side of the block performs a ballistic intercepting function and the other one serves as a ballistic protection. If one of the sides wears, the block can be reused by turning it 180° and using it as a ballistic interceptor wall. GR ballistic blocks withstand the highest number of hits from currently known ballistic blocks with bullets fired from side-firing firearms, central ignition and smoothbore firearms, in particular 9mm, 5.56mm and 7.62mm caliber and are fully recyclable. The characteristics of the GR ballistic block allow the construction of very high ballistic structures with increased resistance to bullet penetration. The structural construction of the GR ballistic block and the structures constructed with its help exhibit the features of the full recycling cycle of the GR ballistic block, ballistic granules and projectiles that will be retained inside it by ballistic granules.
