Description

Impact-resistant wall
Technical Field
The application relates to the technical field of explosion-proof and impact-proof, in particular to an impact-resistant wall.
Background
Since the introduction of thermal weapons into the military, explosives have essentially dominated modern war. However, as terrorists become increasingly rampant, explosives are also often used in terrorist activities. According to incomplete statistics, dozens of terrorist attacks with larger scale occur in the world between 1983 and 2000, and the number of death people exceeds two thousand. Except three of them caused by hijacking airplanes, the rest are all buildings attacked by bombs, and the attacked buildings are mainly national important organs such as government departments, embassies and the like. From 2000 to date, the number of terrorist attacks that caused major casualties has reached more than 80, resulting in countless casualties, most of which are suicide car bombs. Particularly, in the '911 event' in new york, usa, at 9/11/2001, suicide bomb attackers hijack civil airliners to the world trade center, resulting in the death of 2977.
Therefore, for some specific important buildings, such as military bases, nuclear power plants, refuges, embassy, and other national important institutions, the loss caused by the buildings is difficult to estimate once the buildings are lost. Therefore, special anti-knock designs for these buildings are needed to enhance the safety of the buildings. However, the research on buildings in explosion at home and abroad is not complete at present, and the research is mainly focused on military buildings, petrochemical industry and other flammable and explosive industries, but no complete specifications are provided for common civil buildings and non-structural buildings such as doors and windows.
At present, the main ideas of the antiknock design in the prior art are: the impact caused by the explosion is fully borne by the concrete or the steel plate. However, in order to completely resist the destructive force of explosion, the wall thickness of the rigid wall is generally very thick, and the anti-explosion effect is not obvious. In addition, the over-thick wall body is easy to form a weak surface at the joint due to over self weight, and the wall body is easy to collapse after explosion to cause secondary damage.
Many scholars at home and abroad study the anti-explosion performance of different materials to replace the traditional steel structure and concrete structure. At present, the focus of domestic and foreign research is to design the wall body into a multilayer composite structure by adopting porous materials or light materials. The main materials are as follows: rigid polyurethane foam, polypropylene fiber, steel fiber, foamed aluminum, rubber concrete, high-resistance concrete and the like.
Disclosure of Invention
In view of the above, the invention provides an anti-impact wall, so that the anti-explosion and anti-impact performance of the wall can be effectively improved.
The technical scheme of the invention is realized as follows:
an impact resistant wall, comprising: a front panel, a rear panel and a multi-cavity panel;
the multiple chamber panel includes: a cavity front plate and a cavity rear plate; a cavity is arranged between the cavity front plate and the cavity rear plate; the cavity is filled with granular energy-consuming materials;
the front panel is arranged on the outer surface of the cavity front plate of the multi-cavity plate;
the rear panel is arranged on the outer surface of the cavity rear plate of the multi-cavity plate;
the front panel is provided with a weak strip; the stiffness at the weakened strip is less than the stiffness of the front panel.
Preferably, the line of weakening comprises a plurality of pre-defined apertures located at pre-defined positions.
Preferably, the preset hole includes: a stop block and a soft layer;
a groove is formed in the stop block; soft layers are arranged at two ends of the stop block;
the weak layer is made of a brittle material.
Preferably, the brittle material is concrete, mortar, glass fiber reinforced plastic or carbon fiber cloth.
Preferably, a plurality of toothed plates are arranged on the inner sides of the cavity front plate and the cavity rear plate of the multi-cavity plate, and the toothed plates on the cavity front plate and the cavity rear plate are arranged in a staggered mode.
Preferably, one or more transverse piles are arranged in the cavity of the multi-cavity plate;
the transverse piles are uniformly distributed in the vertical direction and are arranged in a staggered mode in the thickness direction of the multi-cavity plate.
Preferably, one or more transverse partition plates are arranged in the cavity of the multi-cavity plate;
the plurality of transverse partition plates are uniformly distributed in the vertical direction, and the left end and the right end of each transverse partition plate are respectively connected with the cavity front plate and the cavity rear plate;
one or more vertical partition plates are arranged between every two transverse partition plates, and the upper end and the lower end of each vertical partition plate are respectively connected with the two transverse partition plates.
Preferably, the front panel and the multilumen panel are made of a fibre-reinforced composite material.
Preferably, the fiber reinforced composite material is any one of aramid fiber reinforced composite material, glass fiber reinforced composite material, basalt fiber reinforced composite material, carbon fiber reinforced composite material and plant fiber.
Preferably, the granular energy dissipation material is rubber, gravel chips, lead chips or soil.
As can be seen from the above, in the impact-resistant wall body of the present invention, since the weak band is disposed on the outer surface of the front panel, and the stiffness of the weak band is less than the stiffness of the other portions of the front panel where the weak band is not disposed, when the impact force such as an explosive shock wave is applied, the weak band on the front panel is broken as a broken layer under certain deformation, so that the whole front panel can be subjected to the intended bending and breaking, and part of the energy of the explosive shock wave is absorbed and consumed by the breaking, and the whole front panel is separated; the front panel after falling off is rebounded by the elastic force after impacting the cavity front panel of the multi-cavity plate and moves towards the direction of the shock wave in the opposite direction, so that the shock wave energy can be consumed while the shock wave is blocked, and the shock of the shock wave is buffered.
In addition, because the cavity is arranged in the multi-cavity plate and is filled with the granular energy-consuming materials, when the multi-cavity plate is impacted by explosion shock waves and the like, the multi-cavity plate is extruded and deformed under the action of the shock waves, and the front cavity plate and the rear cavity plate of the multi-cavity plate extrude the granular energy-consuming materials filled in the cavity, so that the granular energy-consuming materials are mutually extruded and rubbed, the energy of the shock waves can be consumed through the friction among the granular energy-consuming materials and between the granular energy-consuming materials and the front cavity plate and between the granular energy-consuming materials and the rear cavity plate, and the energy of the shock waves can be further absorbed and consumed through the deformation of the materials and the scattering of the granular energy-consuming materials, so that; in addition, the particle energy dissipation material can play a role in supporting the cavity while dissipating energy.
In addition, the outer surface of the cavity back plate of the multi-cavity plate is also provided with a back panel, the back panel can further absorb and consume shock wave energy and can ensure that the shock wave does not break under the action of the shock wave, so that the front panel, the multi-cavity plate and the particle energy consumption material can work normally under the action of the shock wave and cannot penetrate through the back panel, and finally, the building or people behind the wall body can be guaranteed. Therefore, the anti-explosion and anti-impact wall can effectively improve the anti-explosion and anti-impact performance of the wall.

Detailed Description
In order to make the technical scheme and advantages of the invention more apparent, the invention is further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, an impact-resistant wall according to an embodiment of the present invention includes: a front panel 11, a rear panel 12 and a multi-cavity panel;
the multiple chamber panel includes: a cavity front plate 13 and a cavity rear plate 14; a cavity 15 is arranged between the cavity front plate 13 and the cavity rear plate 14; the cavity 15 is filled with granular energy-consuming materials 17;
the front panel 11 is arranged on the outer surface of a cavity front plate 13 of the multi-cavity plate;
the back panel 12 is disposed on an outer surface of a cavity back plate 14 of the multi-cavity plate;
the front panel 11 is provided with a weak strip 16; the stiffness at the weakened strip 16 is less than the stiffness of the front panel 11.
In the technical scheme of the invention, according to the anti-explosion and anti-impact theory and the requirement of actual conditions, a weak strip is arranged on the outer surface of the front panel in advance, and the rigidity of the weak strip is smaller than that of other positions on the front panel where the weak strip is not arranged, so that after the weak strip is arranged on the front panel, the rigidity of each position on the front panel can be distributed according to a preset rule (for example, a preset shape, a preset position, a preset area and the like). Therefore, when the front panel is subjected to impact force such as explosion shock wave and the like, the front panel is subjected to load deformation and moves inwards under the action of the shock wave, the weak belt on the front panel is used as a fracture layer and is firstly fractured under certain deformation, so that the whole front panel can be subjected to expected designed bending fracture, and part of energy of the explosion shock wave is absorbed and consumed through fracture and is separated integrally; the front panel after falling off is rebounded by the elastic force after impacting the cavity front panel of the multi-cavity plate and moves towards the direction of the shock wave in the opposite direction, so that the shock wave energy can be consumed while the shock wave is blocked, and the shock of the shock wave is buffered.
In addition, because the cavity is arranged in the multi-cavity plate and is filled with the granular energy-consuming materials, when the multi-cavity plate is impacted by explosion shock waves and the like, the multi-cavity plate is extruded and deformed under the action of the shock waves, and the front cavity plate and the rear cavity plate of the multi-cavity plate extrude the granular energy-consuming materials filled in the cavity, so that the granular energy-consuming materials are mutually extruded and rubbed, the energy of the shock waves can be consumed through the friction among the granular energy-consuming materials and between the granular energy-consuming materials and the front cavity plate and between the granular energy-consuming materials and the rear cavity plate, and the energy of the shock waves can be further absorbed and consumed through the deformation of the materials and the scattering of the granular energy-consuming materials, so that; in addition, the particle energy dissipation material can play a role in supporting the cavity while dissipating energy.
In addition, the outer surface of the cavity back plate of the multi-cavity plate is also provided with a back panel, the back panel is made of a material with enough toughness, the shock wave energy can be further absorbed and consumed, and the front panel, the multi-cavity plate and the particle energy consumption material can be ensured not to be broken under the action of the shock wave, so that the front panel, the multi-cavity plate and the particle energy consumption material can work normally under the action of the shock wave and cannot penetrate through the back panel.
In addition, in the technical solution of the present invention, the above-mentioned weak area can be realized by using a plurality of specific implementation manners according to the requirements of the practical application environment, and the technical solution of the present invention will be described in detail below by taking one of the specific implementation manners as an example.
For example, in a preferred embodiment of the invention, the line of weakening may comprise a plurality of pre-set apertures located at pre-set positions, as shown in figure 2.
For example, a plurality of preset positions may be previously determined on the front panel, and then a plurality of preset holes may be respectively provided at the preset positions, thereby forming a weak line.
In addition, in the technical solution of the present invention, the preset holes may be implemented by using a plurality of specific implementation manners according to the requirements of the actual application environment.
For example, in a preferred embodiment of the present invention, the preset holes 16 comprise: a stopper 21 and a weak layer 22;
a groove 23 is arranged on the stop block 21; soft layers 22 are arranged at two ends of the stop block 21;
the weak layer 22 is made of a brittle material.
The brittle material can be subjected to brittle fracture under certain deformation.
For example, in a preferred embodiment of the present invention, the brittle material may be: concrete, mortar, glass fiber reinforced plastic or carbon fiber cloth.
In addition, in the technical scheme of the invention, the size and the shape of the preset holes and the specific positions and/or the distribution density of the preset holes on the wall surface can be designed in advance according to the requirements of the practical application environment.
For example, in a preferred embodiment of the present invention, the plurality of preset holes are uniformly arranged at a preset interval on the peripheral edge of the front panel (for example, as shown in fig. 3).
Of course, in the technical solution of the present invention, the plurality of preset holes may also form various patterns with other shapes according to the needs of the actual application situation, and are not described herein again.
In addition, in the technical solution of the present invention, the multi-cavity plate can be implemented by using various specific implementations according to the requirements of the practical application environment, and the technical solution of the present invention will be described in detail below by taking several specific implementations as examples.
In a first embodiment, the multi-cavity plate is an interlaced tooth plate multi-cavity plate.
For example, in the first embodiment, a plurality of toothed plates 41 are disposed on the inner sides of the cavity front plate 13 and the cavity rear plate 14 of the multi-cavity plate, and the plurality of toothed plates on the cavity front plate 13 and the cavity rear plate 14 are staggered with each other.
Accordingly, the multi-cavity plate provided with the tooth plates may be referred to as an interleaved tooth plate multi-cavity plate, as shown in fig. 4 and 5. The plurality of toothed plates on the cavity front plate and the cavity rear plate are inserted in a staggered mode, and a continuous cavity is formed between the toothed plates.
Because the cavity is filled with the particle energy dissipation material, when the cavity is impacted by explosion shock waves and other impact forces, the front panel can be impacted to extrude the cavity of the multi-cavity plate under the action of the shock waves, and the toothed plates in the multi-cavity plate are extruded and rubbed with the particle energy dissipation material under the driving of the cavity front panel and the cavity rear panel, so that the shock wave energy can be dissipated in the extrusion and rubbing process.
In a second embodiment, the multi-cavity plate is a cross-pile type multi-cavity plate.
For example, in the second embodiment, one or more transverse piles 51 are disposed in the cavity 15 of the multi-cavity plate, and the transverse piles 51 are uniformly distributed in the vertical direction and are staggered in the thickness direction of the multi-cavity plate.
Therefore, the multi-cavity plate provided with the transverse piles may be referred to as a transverse pile type multi-cavity plate, as shown in fig. 6 and 7. The staggered transverse piles can divide the cavity of the multi-cavity plate into a plurality of continuous cavities.
Because the cavity is filled with the particle energy-consuming materials, when the cavity is impacted by explosion shock waves and the like, the cavity front plate and the cavity rear plate of the multi-cavity plate extrude the particle energy-consuming materials under the action of the shock waves, the particle energy-consuming materials are continuously divided, combined and rubbed under the division of the transverse piles, and the shock wave energy is dissipated through the interaction between a series of particle energy-consuming materials and the transverse piles.
In a third specific embodiment, the multi-cavity plate is an overlapping rectangular multi-cavity plate.
For example, in the third embodiment, one or more transverse partition plates 61 are arranged in the cavity of the multi-cavity plate; the plurality of transverse partition plates 61 are uniformly distributed in the vertical direction, and the left end and the right end of each transverse partition plate 61 are respectively connected with the cavity front plate 13 and the cavity rear plate 14; one or more vertical partition plates 62 are arranged between every two transverse partition plates 61, and the upper end and the lower end of each vertical partition plate 62 are respectively connected with the two transverse partition plates 61.
Therefore, the multi-well plate provided with the above-described lateral and vertical partition plates may be referred to as an overlapping rectangular multi-well plate, as shown in fig. 8 and 9. The cavity of the multi-cavity plate can be divided into a plurality of cuboid cavities with different sizes by the transverse partition plate and the vertical partition plate.
Because the cuboid cavities are filled with the granular energy-consuming materials, when the impact force such as explosion shock waves and the like is received, the multi-cavity plate is extruded and deformed under the action of the shock waves, the cuboid cavities in the multi-cavity plate are also extruded and deformed, and the granular energy-consuming materials in the cuboid cavities are extruded and rubbed with each other, so that the shock wave energy is dissipated; in addition, the particle energy dissipation material can play a role in supporting the cuboid cavity while dissipating energy.
Further, by way of example, in a preferred embodiment of the invention, the front panel and the multilumen panel are made of Fiber Reinforced composite (FRP). Therefore, the high strength characteristic of the FRP can be further utilized to resist the huge tensile stress under the impact action and absorb and consume the energy of the shock wave.
Specifically, the FRP may be any one of aramid fiber reinforced composite material (AFRP), glass fiber reinforced composite material (GFRP), basalt fiber reinforced composite material (BFRP), carbon fiber reinforced composite material (CFRP), plant fiber (for example, wood fiber, bamboo fiber, or herbal fiber), and the like.
In addition, as an example, in a preferred embodiment of the present invention, the particulate energy-consuming material may be rubber, gravel, lead chips, or soil, which has a good energy-absorbing effect and a large deformation capacity, and can convert impact energy into compression energy and particle kinetic energy by material deformation and particle scattering energy consumption, so as to absorb and consume the energy of the impact energy.
Further, by way of example, in a preferred embodiment of the invention, the rear panel is made of a material having sufficient toughness (e.g., basalt fiber or steel, etc.). Therefore, the high-strength characteristic of the tough material can be further utilized to resist the huge tensile stress under the impact action, absorb and consume the energy of the shock waves, ensure that the shock waves are not broken under the action of the shock waves, and ensure that the front panel, the multi-cavity plate and the particle energy-consuming material can normally work under the impact action without penetrating through the rear panel.
In the technical scheme of the invention, the main energy consumption mechanism of the anti-impact wall body is as follows:
1. and (3) breaking energy consumption: since the front panel is provided with the fracture layer (for example, a weak strip composed of a plurality of preset holes), and the fracture layer is provided with the brittle material which can be fractured under certain deformation in advance, under the action of the shock wave, when the deformation reaches a certain degree, the fracture layer is fractured, so that the energy of the shock wave can be consumed through the fracture of the fracture layer.
2. Back-flushing energy consumption: after the fracture layer is fractured, the front panel falls off integrally, and the front panel is rebounded by elastic force after impacting the cavity plate and moves towards the direction of the shock wave in the opposite direction, so that the shock wave energy can be consumed while the shock wave is blocked.
3. Energy consumption in motion: various components of the impact-resistant wall body fall off after being impacted by impact waves, and the fallen components and the particle energy dissipation materials can convert the energy of the impact waves into kinetic energy after absorbing the energy of the impact waves, so that the energy of the impact waves can be dissipated through scattering energy dissipation.
4. Deformation energy consumption: the multi-cavity plate, the front panel and the rear panel deform under the impact action of the shock waves, so that the energy of the shock waves can be converted into deformation energy and the energy of the shock waves.
5. And (3) extruding energy consumption: the granular energy-consuming materials are extruded under the impact action of the shock waves, and the originally dispersed granular energy-consuming materials are extruded together, so that the intermolecular force and the extrusion force can be utilized for counter balance, and finally the energy is dissipated through heat.
6. Friction energy consumption: the particle energy dissipation materials rub against each other under the violent movement, so that the energy of the shock wave can be dissipated through the friction among the particle energy dissipation materials and between the particle energy dissipation materials and the panel.
In summary, in the technical solution of the present invention, since the weak band is disposed on the outer surface of the front panel, and the stiffness of the weak band is less than the stiffness of the front panel at other locations where the weak band is not disposed, when the front panel is subjected to an impact force such as an explosive shock wave, the weak band on the front panel as a fracture layer will fracture first under certain deformation under the action of the shock wave, so that the entire front panel can be subjected to a bending fracture of a desired design, and the fracture absorbs and consumes part of energy of the explosive shock wave, and the energy is wholly separated; the front panel after falling off is rebounded by the elastic force after impacting the cavity front panel of the multi-cavity plate and moves towards the direction of the shock wave in the opposite direction, so that the shock wave energy can be consumed while the shock wave is blocked, and the shock of the shock wave is buffered.
In addition, because the cavity is arranged in the multi-cavity plate and is filled with the granular energy-consuming materials, when the multi-cavity plate is impacted by explosion shock waves and the like, the multi-cavity plate is extruded and deformed under the action of the shock waves, and the front cavity plate and the rear cavity plate of the multi-cavity plate extrude the granular energy-consuming materials filled in the cavity, so that the granular energy-consuming materials are mutually extruded and rubbed, the energy of the shock waves can be consumed through the friction among the granular energy-consuming materials and between the granular energy-consuming materials and the front cavity plate and between the granular energy-consuming materials and the rear cavity plate, and the energy of the shock waves can be further absorbed and consumed through the deformation of the materials and the scattering of the granular energy-consuming materials, so that; in addition, the particle energy dissipation material can play a role in supporting the cavity while dissipating energy.
In addition, the outer surface of the cavity back plate of the multi-cavity plate is also provided with a back panel, the back panel can further absorb and consume shock wave energy and can ensure that the shock wave does not break under the action of the shock wave, so that the front panel, the multi-cavity plate and the particle energy consumption material can work normally under the action of the shock wave and cannot penetrate through the back panel, and finally, the building or people behind the wall body can be guaranteed. Therefore, the anti-explosion and anti-impact wall can effectively improve the anti-explosion and anti-impact performance of the wall.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
