Description

Technical Field

[0001] The utility model relates to the technical field of building walls, in particular to a protective composite explosion-proof wall structure. Background Art

[0002] Civil air defense projects refer to underground protective buildings built separately to ensure the sheltering of personnel and materials, civil air defense command, and medical rescue in wartime, as well as basements built in combination with ground buildings that can be used for air defense in wartime. Civil air defense projects are important facilities for preventing sudden enemy attacks, effectively sheltering personnel and materials, and preserving war potential. Explosion-proof walls refer to walls that are resistant to explosion pressure, also known as explosion-resistant walls and explosion-resistant walls. They are mostly located in factories or warehouses with explosion hazards. In civil air defense facilities, in order to ensure the safety of personnel, explosion-proof walls naturally become an indispensable protective barrier.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the existing civil air defense walls have a single structure. In order to completely resist the destructive force of the explosion, most of them use concrete or steel plates to fully bear the impact caused by the explosion. This kind of purely rigid wall generally relies on its own strength to resist the impact caused by the explosion. After the explosion, its own strength is damaged, making it prone to collapse. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a protective composite explosion-proof wall structure.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a protective composite explosion-proof wall structure, comprising a first wall, a fireproof layer is fixedly arranged on the side wall of the first wall, a fiber cement layer is fixedly arranged on the side wall of the fireproof layer away from the first wall, a second wall is fixedly arranged on the side wall of the fiber cement layer away from the fireproof layer, and a plurality of protrusions are installed on the side wall of the first wall away from the second wall.

[0006] By adopting the above technical solution, when the wall is impacted by an explosion during use, the first wall is first impacted by the explosion. Subsequently, the impact is transmitted to the fiber cement layer. During this process, the fiber cement layer absorbs the impact generated by the explosion, thereby reducing the impact on the second wall, thereby reducing the probability of damage to the first wall and the second wall, and further reducing the probability of collapse of the first wall and the second wall. In addition, the fireproof layer reduces the probability of the wall being ignited after the explosion, thereby further reducing the probability of wall collapse.

[0007] Furthermore, a plurality of mounting grooves are provided on the side wall of the protrusion, a plurality of reinforcing plates are distributed in an array on the side wall of the first wall away from the second wall, energy absorbing columns are fixedly provided on the side walls of the plurality of reinforcing plates away from the first wall, and one end of the energy absorbing column away from the reinforcing plate is fixed to the inner wall of the mounting groove.

[0008] By adopting the above technical solution, when an explosion occurs, during the transmission of the explosion shock wave, the explosion shock wave first contacts the convex block. Under the action of the impact force, due to the concentrated impact force, the weak rigidity area of ​​the reinforcing plate inside the convex block as a weak surface will be deformed first, thereby causing the first wall to bend and collapse as expected in the design, thereby effectively improving the explosion resistance of the wall. In addition, the energy-absorbing column can also absorb part of the impact force.

[0009] Furthermore, an explosion-proof plate is fixedly disposed on the side walls of the plurality of protrusions away from the first wall.

[0010] By adopting the above technical solution, the explosion-proof plate has the effect of absorbing the explosion impact force, thereby reducing the explosion impact force on the protrusion and the wall, thereby reducing the probability of wall collapse.

[0011] Furthermore, a rubber layer is fixedly arranged on the side wall of the first wall away from the second wall, a plurality of protrusions are fixedly arranged on the side wall of the rubber layer away from the first wall, and a plurality of reinforcing plates are fixedly arranged on the side wall of the rubber layer away from the first wall.

[0012] By adopting the above technical solution, when the shock wave received by the bump is transmitted to the rubber layer, the rubber layer made of rubber can effectively absorb the impact force of the explosion due to the elasticity of rubber, thereby reducing the impact force of the explosion received by the first wall, thereby reducing the probability of wall collapse.

[0013] Furthermore, a plurality of reinforcing plates are fixedly provided with reinforcing columns on side walls away from the first wall, and one end of the reinforcing column away from the reinforcing plate is fixedly provided on the inner wall of the mounting groove.

[0014] By adopting the above technical solution, the reinforcing column improves the strength of the protrusion, thereby reducing the probability of the protrusion being deformed during daily use, thereby improving the stability of the device. In addition, when an explosion occurs, the reinforcing column breaks under the action of the impact force, thereby reducing the probability of the reinforcing column affecting the energy absorbing column, thereby improving the stability of the device.

[0015] Furthermore, the energy absorbing column is an energy absorbing column made of elastic material.

[0016] By adopting the above technical solution, the energy absorbing column made of elastic material improves the working efficiency of the energy absorbing column, thereby improving the effect of the energy absorbing column in absorbing impact force.

[0017] Furthermore, the first wall is a first wall made of a steel plate, and the second wall is a second wall made of a steel plate.

[0018] By adopting the above technical solution, the first wall and the second wall made of steel plates improve the strength of the wall itself, thereby reducing the probability of wall collapse.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, when the wall is impacted by an explosion during use, the first wall is impacted by the explosion first. Then, the impact is transmitted to the fiber cement layer. During this process, the fiber cement layer absorbs the impact of the explosion, thereby reducing the impact on the second wall, thereby reducing the probability of damage to the first wall and the second wall, and further reducing the probability of collapse of the first wall and the second wall. In addition, the fireproof layer reduces the probability of the wall being ignited after the explosion, thereby further reducing the probability of the wall collapse;

[0021] 2. In this application, when an explosion occurs, during the transmission of the explosion shock wave, the explosion shock wave first contacts the protrusion. Under the action of the impact force, due to the concentrated impact force, the weak rigidity area of ​​the reinforcement plate inside the protrusion as a weak surface will be deformed first, thereby causing the first wall to bend and collapse as expected in the design, thereby effectively improving the explosion resistance of the wall. In addition, the energy-absorbing column can also absorb part of the impact force;

[0022] 3. In the present application, the explosion-proof plate has the effect of absorbing the explosion impact force, thereby reducing the explosion impact force on the protrusion and the wall, thereby reducing the probability of wall collapse. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] like Figure 1-4 As shown, the embodiment of the present application discloses a protective composite explosion-proof wall structure, including a first wall 1, a fireproof layer 11, a fiber cement layer 12, a second wall 13, a protrusion 14, a reinforcing plate 3, an energy absorbing column 31, an explosion-proof plate 4, a rubber layer 5 and a reinforcing column 6. The first wall 1 is a rectangular parallelepiped structure, and the fireproof layer 11 is fixedly arranged on the side wall of the first wall 1 to improve the fireproof effect of the wall. The fiber cement layer 12 is fixedly arranged on the side wall of the fireproof layer 11 away from the first wall 1 to absorb the impact force generated by the explosion. The second wall 13 is a rectangular parallelepiped structure, and the second wall 13 is fixedly arranged on the side wall of the fiber cement layer 12 away from the fireproof layer 11. There are a plurality of protrusions 14, and a plurality of protrusions 14 are installed on the side wall of the first wall 1 away from the second wall 13.

[0030] When the wall is impacted by an explosion during use, the first wall 1 is impacted by the explosion first. Then, the impact is transmitted to the fiber cement layer 12. During this process, the fiber cement layer 12 absorbs the impact of the explosion, thereby reducing the impact on the second wall 13, thereby reducing the probability of damage to the first wall 1 and the second wall 13, and further reducing the probability of collapse of the first wall 1 and the second wall 13. In addition, the fireproof layer 11 reduces the probability of the wall being ignited after the explosion, thereby further reducing the probability of the wall collapsing.

[0031] A plurality of mounting grooves 2 are provided on the side wall of the protrusion 14, and a plurality of reinforcing plates 3 are provided and are distributed in an array on the side wall of the first wall 1 away from the second wall 13. The energy absorbing column 31 is a cylindrical structure with a horizontal axis. A plurality of energy absorbing columns 31 are provided and are respectively fixedly arranged on the side walls of the plurality of reinforcing plates 3 away from the first wall 1, and one end of the energy absorbing column 31 away from the reinforcing plate 3 is fixed to the inner wall of the mounting groove 2.

[0032] When an explosion occurs, during the transmission of the explosion shock wave, the explosion shock wave first contacts the protrusion 14. Under the action of the impact force, due to the concentrated impact force, the weak rigidity area of ​​the reinforcing plate 3 inside the protrusion 14 as a weak surface will be deformed first, thereby causing the first wall 1 to bend and collapse as expected, thereby effectively improving the explosion resistance of the wall. In addition, the energy absorbing column 31 can also absorb part of the impact force.

[0033] In order to reduce the probability of wall collapse, a plurality of protrusions 14 are fixedly provided with explosion-proof panels 4 on the sidewalls away from the first wall 1. The explosion-proof panels 4 have the effect of absorbing the impact force of explosions, thereby reducing the impact force of explosions on the protrusions 14 and the wall, thereby reducing the probability of wall collapse.

[0034] The rubber layer 5 is fixedly arranged on the side wall of the first wall 1 away from the second wall 13 , a plurality of protrusions 14 are fixedly arranged on the side wall of the rubber layer 5 away from the first wall 1 , and a plurality of reinforcing plates 3 are fixedly arranged on the side wall of the rubber layer 5 away from the first wall 1 .

[0035] When the shock wave received by the protrusion 14 is transmitted to the rubber layer 5, the rubber layer 5 made of rubber can effectively absorb the impact force of the explosion due to the elasticity of rubber, thereby reducing the impact force of the explosion received by the first wall 1, thereby reducing the probability of wall collapse.

[0036] The reinforcing column 6 is a cylindrical structure with a horizontal axis. A plurality of reinforcing columns 6 are provided and are respectively fixedly arranged on the side walls of the plurality of reinforcing plates 3 away from the first wall 1 . One end of the reinforcing column 6 away from the reinforcing plate 3 is fixedly arranged on the inner wall of the mounting groove 2 .

[0037] The reinforcing column 6 increases the strength of the protrusion 14, thereby reducing the probability of deformation of the protrusion 14 during daily use, thereby improving the stability of the device. In addition, when an explosion occurs, the reinforcing column 6 breaks under the action of the impact force, thereby reducing the probability of the reinforcing column 6 affecting the energy absorbing column 31, thereby improving the stability of the device.

[0038] In order to improve the effect of the energy absorbing column 31 in absorbing impact force, the energy absorbing column 31 is made of elastic material. The energy absorbing column 31 made of elastic material improves the working efficiency of the energy absorbing column 31, thereby improving the effect of the energy absorbing column 31 in absorbing impact force.

[0039] In order to reduce the probability of wall collapse, the first wall 1 is a first wall 1 made of steel plates, and the second wall 13 is a second wall 13 made of steel plates. The first wall 1 and the second wall 13 made of steel plates increase the strength of the wall itself, thereby reducing the probability of wall collapse.

[0040] The use principle of a protective composite explosion-proof wall structure in this embodiment is as follows: when the wall is impacted by an explosion during use, the first wall 1 is first impacted by the explosion. Subsequently, the impact is transmitted to the fiber cement layer 12. During this process, the fiber cement layer 12 absorbs the impact generated by the explosion, thereby reducing the impact on the second wall 13, thereby reducing the probability of damage to the first wall 1 and the second wall 13, and further reducing the probability of collapse of the first wall 1 and the second wall 13. In addition, the fireproof layer 11 reduces the probability of the wall being ignited after the explosion, thereby further reducing the probability of the wall collapsing.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
