Detailed Description
The invention will be described in further detail with reference to the drawings and specific examples.
As shown in fig. 1 and 2, the directional reinforced concrete penetration-resistant structure of the embodiment comprises a reinforced concrete structural layer 1, wherein a plurality of reinforcing steel bars 11 capable of axially impacting an external penetration body are wrapped in the reinforced concrete structural layer 1. The penetration body resists the penetration structure from outside to inside along the thickness direction of the penetration resistant structure in a penetration mode to damage so as to break through the protection of the penetration resistant structure on the inner space. In the process, if the structure of the penetration resistant body can be damaged, the penetration capability of the penetration resistant body is greatly weakened, so that the defense capability of the penetration resistant body is relatively enhanced on the premise of not changing the structure thickness and the material strength of the penetration resistant body. Through densely arranging the reinforcing steel bars 11 which are distributed in parallel or in a radial shape and have the length direction basically consistent with the thickness direction of the reinforced concrete structure layer 1 in the reinforced concrete structure layer 1, on one hand, the structure damage can be caused to the penetration body and the penetration body is forced to deflect, when the movement direction of the penetration body is consistent with the length direction of the reinforcing steel bars 11 or basically consistent with the length direction of the penetration body, the end parts of the reinforcing steel bars 11 collide with the penetration body, and the penetration body is deflected due to extremely uneven resistance of the warheads of the penetration body, so that the penetration body is subjected to higher resistance. When the penetration body continues to move towards the inner side of the defense industry, the reinforcing steel bars 11 further form extrusion with the surface of the penetration body, and damage and even penetration are caused to the structure of the penetration body under the extrusion action, so that the penetration body is prevented from continuing to move; on the other hand, the penetration resistance of the structure can be obviously improved, and the mechanical property of the reinforced concrete structure is improved in a crossing mode due to the fact that the high-strength steel bars 11 are reconfigured in the thickness direction of the structure, so that the penetration resistance and the shearing resistance of the reinforced concrete structure can be obviously improved. For the single mode improvement defense industry's that increases structure thickness and promotion material intensity among the prior art anti penetration ability, the utility model discloses need not additionally increase occupation space and low in cost, only in concrete structure directional increase reinforcing bar 11 alright cause destruction and force its anti striking ability partial to, improvement defense industry to the penetration body in the invasion structure.
In this embodiment, the reinforcing bars 11 are distributed in parallel or in a radial shape, and the length direction thereof is substantially the same as the thickness direction of the reinforced concrete structural layer 1. In order to penetrate the defence works at the shortest distance, it is generally chosen to attack in a direction perpendicular to the penetration-resistant body (i.e. in the thickness direction of the penetration-resistant body). For this reason, in the present embodiment, the arrangement of the reinforcing bars 11 is set to be consistent with the movement track of the penetration body (i.e., the length direction of the reinforcing bars 11 is consistent with or substantially consistent with the thickness direction of the penetration-resistant body), so that the reinforcing bars 11 can be ensured to perform frontal collision on the penetration body, thereby enhancing the effect of damaging the penetration body and forcing it to deflect.
In this embodiment, each reinforcement 11 is connected to a reinforcement mesh 12 wrapped around the reinforced concrete structure layer 1. Because reinforcing bar 11 sets up for the interval, the penetration body is when penetrating reinforced concrete structural layer 1, and reinforcing bar 11 will produce the trend of transversely keeping away from the penetration body and removing in the extrusion process of the penetration body. In order to avoid or reduce this tendency, a reinforcing mesh 12 for pulling the reinforcing bars 11 transversely is provided in the reinforced concrete structural layer 1. The reinforcing mesh 12 integrally connects the reinforcing bars 11, and when some of the reinforcing bars 11 are laterally deviated, the remaining reinforcing bars 11 provide a counter pressure to limit the deviation tendency to some extent, thereby enhancing the impact of the reinforcing bars 11 with the penetration body.
In this embodiment, the reinforcing mesh 12 is perpendicular to the reinforcing bars 11, and after the penetration body enters the reinforced concrete structure layer 1, the kinetic energy is attenuated by impact, so that the extrusion force of the penetration body on the reinforcing bars 11 is gradually weakened from the outer side to the inner side. In contrast, in the present embodiment, the reinforcing mesh 12 can be arranged from the outside to the inside at equal intervals or gradually distributed in a sparse manner to match with the transverse stress of the reinforcing steel bar 11, that is, in the initial stage of the impact (outside of the reinforced concrete structure layer 1), the reinforcing mesh 12 with higher density and larger diameter is arranged to enhance the traction effect, and after entering the middle and later stages of the impact (the middle and inside of the reinforced concrete structure layer 1), the arrangement interval of the reinforcing mesh 12 can be gradually increased to reduce the manufacturing cost.
In this embodiment, a bottom steel structure layer 2 is attached to the inner side of the reinforced concrete structure layer 1. Because concrete is a brittle material, it is easily broken and falls off when being impacted. In order to avoid crushing, falling and smashing an internal space due to the reinforced concrete structure layer 1, a bottom steel structure layer 2 is attached to the inner side of the reinforced concrete structure layer. Through setting up end steel structural layer 2, can support the fragment that broken reinforced concrete structural layer 1 dropped on the one hand, the invasion body that another direction can also be to penetrating reinforced concrete structural layer 1 causes the block again.
Preferably, the bottom steel structure layer 2 is made of low-carbon steel, has high strength, has good toughness due to low carbon content, can effectively reduce the brittle failure probability of the structure when suffering impact, and plays a role in warning internal personnel by generating obvious deformation.
In this embodiment, reinforcing bar 11 is logical long muscle, and its one end links to each other with end steel construction layer 2, and the other end is wrapped up by the protective layer outward to avoid causing rust or corruption with external environment direct contact. Reinforcing bar 11 links to each other with end steel construction layer 2 and forms whole back, will greatly strengthen the wholeness of structure, when reinforced concrete structural layer 1 suffered the impact, end steel construction layer 2 provides reverse support to reinforced concrete structural layer 1 through reinforcing bar 11 to reinforcing overall structure's anti ability of hitting.
In this embodiment, the bottom steel structure layer 2 is provided with a plurality of protruding structures 21 extending into the reinforced concrete structure layer 1 at intervals on the side where the reinforced concrete structure layer 1 is attached, and the protruding structures 21 and the reinforcing steel bars 11 are arranged in a staggered manner. Through the arrangement of the protruding structures 21, the protruding structures extend into the reinforced concrete structure layer 1 to form tight connection, so that the reinforced concrete structure layer 1 and the bottom steel structure layer 2 can be effectively prevented from being separated, and the structural integrity is enhanced. Preferably, the protrusion structure 21 may employ a shear pin.
In this embodiment, the center distance between adjacent reinforcing bars 11 is 50mm to 200mm. Set up reinforcing bar 11 in reinforced concrete structural layer 1, when reinforcing structure shear strength, can cause structural damage to the penetration body. The diameter of the body of the existing penetration body (such as an accurate guidance weapon, a kinetic energy weapon, a deep drilling weapon and the like) for attacking and defending work is generally not less than 200mm, the center distance of adjacent steel bars 11 is set to be 200mm or less, and the penetration body can be effectively ensured to be in contact with at least one steel bar 11 when entering a reinforced concrete structure layer 1, so that the condition that the function of the penetration body is reduced due to the fact that the steel bars 11 axially collide with the external penetration body when penetrating through gaps of the steel bars 11 is avoided. Meanwhile, considering that the diameter of the steel bars 11 is not less than 20mm, the excessively dense steel bars can greatly increase the construction cost, and may cause the concrete between the steel bars 11 to be hard to be compacted by vibration and influence the structural performance, so the minimum density of the steel bars 11 is set to 50mm. When the reinforcing bars 11 are arranged in a non-parallel manner, the center distance is calculated from the center distance of the outward end of the reinforcing bars 11.
In this embodiment, the concrete part of the reinforced concrete structure layer 1 is selected from common concrete, high-performance concrete or ultra-high-performance concrete. When the defense works are built, different types of concrete can be selected according to the actual defense needs and the cost budget.
For further explanation, another embodiment is provided.
