Description

Technical Field

[0001] This invention belongs to the field of building technology, specifically a radiation-proof composite wall structure and construction process. Background Technology

[0002] Composite walls are building walls composed of two or more different materials. Their purpose is to combine the advantages of various materials to improve the overall performance of the wall. Radiation-proof composite walls play a vital role in building design and application, especially in environments where effective radiation shielding is required. Radiation-proof composite walls are not only an important measure for radiation protection, but also improve the overall performance of buildings and ensure the safety of personnel and equipment.

[0003] Radiation shielding composite walls are generally composed of a combination of various materials. The construction of composite walls usually involves steps such as foundation treatment, accurate installation of materials, and joint treatment. The quality of construction directly affects the protective effect of the wall. Existing radiation shielding walls are usually made of concrete pouring or stacked lead plates of fixed thickness. Once the construction is completed, the shielding effectiveness is fixed. If the intensity of the radiation source changes, it needs to be demolished and rebuilt, which is extremely costly. Therefore, it is necessary to improve it. Summary of the Invention

[0007] Preferably, the first connecting plate assembly includes a first connecting plate, a connecting unit is provided on one side of the first connecting plate, and the first connecting plate is fixedly connected to the first decorative plate and the second decorative plate.

[0008] Preferably, the connecting unit includes a fixing member, a fixing block is fixedly installed on the upper end of one side of the fixing member, a limiting block is fixedly installed on the lower end of one side of the fixing member, and a groove is provided on the inner side of the limiting block, which is movably engaged with the limiting member.

[0009] Preferably, the fixing component includes a fixing plate, a movable part is provided in the middle of the fixing plate, and an electric plate is fixedly connected to both ends of the movable part. The electric plate is disposed between two sets of support frames and does not contact the support frames.

[0010] Preferably, the shielding assembly includes a mounting plate, a shielding cavity plate is provided on the side of the mounting plate near the fixing assembly, a slot is provided on the side of the mounting plate near the shielding cavity plate, and a locking block is provided on the side of the shielding cavity plate near the mounting plate. The mounting plate and the shielding cavity plate are movably connected.

[0011] Preferably, the shielding component is in contact with the shielding cavity plate, the shielding cavity plate is provided with an injection channel and an exhaust port, the exhaust port is a one-way exhaust port, and the inner cavity of the shielding cavity plate is provided with a magnetically sensitive radiation shielding fluid.

[0012] Preferably, the outer wall of the first decorative panel is provided with a control panel, the connecting rope is movably connected to the first decorative panel, and the end of the control component is provided with a slot.

[0013] Preferably, a pneumatic cylinder is provided between the moving part and the fixed plate, a magnetic control block is provided between the fixed block and the limiting block, and a magnetic control block is provided on one side of the connecting plate two, and the two magnetic control blocks attract each other.

[0014] A construction process for a radiation-proof composite wall structure, applied to the aforementioned radiation-proof composite wall structure, includes the following specific steps:

[0015] Step 1: Lay a shock-absorbing pad to reduce the interference of vibration on the precision shielding module;

[0016] Step 2: Erect formwork and tie prestressing tendons, pre-embed spiral pipes, and after pre-embedding, pour concrete for the fixing components to ensure the stability of the fixing components.

[0017] Step 3: After the fixed components are poured, install the support frame, then install the shielding components in sequence, and finally install the first decorative panel, the first connecting plate assembly, the second decorative panel, and the second connecting plate assembly.

[0018] Step 4: When connecting the next radiation-proof composite wall, first connect the first connecting plate assembly and the second connecting plate assembly, then support the formwork and tie the prestressed tendons to the fixing assembly, and then pour the concrete for the fixing assembly.

[0019] Step 5: After all modules are installed, close the valve at the bottom of the wall and inject heavy medium filler from the top to complete the installation of the radiation-proof composite wall.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention utilizes the coordination of structures such as limiting units and connecting units. The limiting component moves away from the second connecting plate, allowing the radiation-proof composite wall to be connected to be installed. The first connecting plate and the connecting unit are aligned with the limiting unit on one side of the second connecting plate. The first connecting plate and the connecting unit are pushed towards the limiting unit, causing the connecting unit to enter the second connecting plate. Pulling the control component again moves the connecting rope, causing the limiting component to engage with the limiting block, thus fixing the newly connected radiation-proof composite wall and preventing instability. This achieves a rapid and secure connection of the wall, avoiding the time-consuming process of wall installation.

[0022] By setting up connecting plates and connecting units, this invention can better connect the first connecting plate assembly and the second connecting plate assembly, thereby better extending and connecting the radiation-proof composite wall, saving time in the installation and connection of the radiation-proof composite wall. Furthermore, when the radiation-proof composite wall needs to be disassembled, it does not require a lot of time, and the disassembled radiation-proof composite wall can be reused, thus saving the cost of the radiation-proof composite wall.

[0023] This invention, through the cooperation of a movable component and an electric plate, uses a pneumatic cylinder to drive the electric plate and the movable component to move. When the electric plate moves, the magnetically sensitive radiation shielding fluid can better absorb and attenuate electromagnetic radiation. It can be adjusted according to specific shielding requirements to adapt to different environments and radiation types. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 6As shown, the present invention provides a radiation-proof composite wall structure, including a first decorative panel 1, a first connecting plate assembly 2 and a second connecting plate assembly 4 disposed on one side of the first decorative panel 1, a second decorative panel 3 disposed on the side of the first connecting plate assembly 2 and the second connecting plate assembly 4 away from the first decorative panel 1, a fixing assembly 5 disposed between the first connecting plate assembly 2 and the second connecting plate assembly 4, a shielding assembly 7 disposed on the side of the first decorative panel 1 and the second decorative panel 3 near the fixing assembly 5, and a support frame 6 fixedly installed on both sides of the fixing assembly 5. The second connecting plate assembly 4 includes a second connecting plate 41, and a limit unit 4 disposed on the inner side of the second connecting plate 41. 2. The connecting plate 41 is fixedly connected to the first decorative plate 1 and the second decorative plate 3. The limiting unit 42 includes a limiting member 421. The upper end of the limiting member 421 is provided with a toothed plate 422. A gear 423 is meshed with one side of the toothed plate 422. A connecting shaft 424 is fixedly installed in the middle of the gear 423. A reset member 425 is provided at the top of the connecting shaft 424. A connecting rope 426 is fixedly connected to the end of the reset member 425. A control member 427 is fixedly connected to the end of the connecting rope 426. A limiting rod 428 is fixedly connected to the middle of the connecting shaft 424. The limiting member 421 is movably connected to the connecting plate 41. A protrusion is provided at the bottom of the limiting member 421.

[0033] The above scheme is adopted: through the cooperation of connecting plate 41 and limiting unit 42, the wall fixing component 5 is first cast, and then the supporting frame 6, shielding component 7, first decorative plate 1, first connecting plate component 2, second decorative plate 3 and second connecting plate component 4 are fixedly connected. The first decorative plate 1 and the second decorative plate 3 are made of galvanized steel plate, which has a certain attenuation capability for radiation and external scattered radiation. It can be used as the outer layer to preferentially intercept low-energy leakage radiation and environmental scattered radiation, reduce the loss of the inner main shielding layer, improve the overall shielding redundancy of the wall, avoid local shielding insufficiency, and the galvanized steel plate has high strength, bending resistance, and With excellent impact resistance, wind pressure resistance, and seismic performance, galvanized steel sheets can be used as the load-bearing structural layer of composite walls. The raw material cost of galvanized steel sheets is low, with a stable supply and complete specifications, making them suitable for the construction of large-area radiation shielding walls. If subsequent adjustments to shielding parameters or the addition of equipment openings are needed, galvanized steel sheets are easy to cut and repair, and the repaired sheets have good sealing properties, without affecting the overall structure and protective performance of the wall. When connecting the next wall section, pulling the control component 427 and the connecting rope 426 causes the connecting rope 426 to retract the reset component 425, which in turn causes the reset component 425 to rotate the connecting shaft 424 and the gear 423. The rotation of the gear 423 then drives the toothed plate 422 and the limiting component. 421 moves, and the two limiting members 421 move towards each other, moving the limiting members 421 away from the connecting plate 2 41. Then, the radiation-proof composite wall to be connected is installed. The connecting plate 1 21 and the connecting unit 22 are aligned with the limiting unit 42 on one side of the connecting plate 2 41. The connecting plate 1 21 and the connecting unit 22 are pushed closer to the limiting unit 42, so that the connecting unit 22 enters the connecting plate 2 41. The control member 427 is pulled again to move the connecting rope 426, which in turn moves the reset member 425. This causes the reset member 425 to reset the gear 423 and the connecting shaft 424, thus resetting the gear. 423 drives the toothed plate 422 and the limiting member 421 to reset. When the limiting member 421 resets, it engages with the limiting block 223, thereby fixing the newly connected radiation-proof composite wall and preventing instability. This achieves the effect of quickly fixing the wall and avoids spending a lot of time installing the wall. After the adjacent walls are connected, there is a certain area between the two walls where no magnetic radiation shielding fluid has been injected. The galvanized steel plate itself has a certain attenuation capability for radiation and external scattered radiation, and can be used as an outer layer to preferentially intercept low-energy leakage radiation and environmental scattered radiation.

[0034] like Figures 2 to 4As shown, the first connecting plate assembly 2 includes a connecting plate 21. A connecting unit 22 is provided on one side of the connecting plate 21. The connecting plate 21 is fixedly connected to the first decorative plate 1 and the second decorative plate 3. The connecting unit 22 includes a fixing member 221. A fixing block 222 is fixedly installed on the upper end of one side of the fixing member 221. A limiting block 223 is fixedly installed on the lower end of one side of the fixing member 221. A groove is provided on the inner side of the limiting block 223, and it is movably engaged with the limiting member 421. The fixing assembly 5 includes a fixing plate 51. A moving member 52 is provided in the middle of the fixing plate 51. Both ends of the moving member 52 are fixedly connected to an electric plate 53. The electric plate 53 is located between the two sets of support frames 6 and does not contact the support frames 6.

[0035] The above solution is adopted: through the cooperation of connecting plate 21 and connecting unit 22, connecting plate 21 is fixedly connected to the first decorative panel 1 and the second decorative panel 3, thereby fixing connecting plate 21, making the first connecting plate assembly 2 more stable during use. One side of the first connecting plate assembly 2 is fixedly connected to the fixing component 5. The connecting unit 22 is connected to connecting plate 21 by nuts and bolts, allowing connecting plate 21 to be disassembled at any time during use. There will be no extra connecting unit 22 on the unconnected side. The limiting block 223 is movably engaged with the limiting member 421, allowing the two radiation-proof composite walls to be connected... When the components are connected, the first connecting plate assembly 2 and the second connecting plate assembly 4 can be better snapped together, thereby extending the connection of the radiation-proof composite wall and saving the installation and connection time of the radiation-proof composite wall. When the radiation-proof composite wall needs to be disassembled, it does not require a lot of time, and the disassembled radiation-proof composite wall can be reused, thus saving the cost of the radiation-proof composite wall. The circuit board 53 is set between the two sets of support frames 6 and does not contact the support frames 6, so as to avoid the circuit board 53 colliding with the support frames 6 when moving, which would cause instability of the radiation-proof composite wall.

[0036] like Figures 3 to 6 As shown, the shielding assembly 7 includes a mounting plate 71. A shielding cavity plate 72 is provided on the side of the mounting plate 71 near the fixing assembly 5. A slot is provided on the side of the mounting plate 71 near the shielding cavity plate 72. A locking block is provided on the side of the shielding cavity plate 72 near the mounting plate 71. The mounting plate 71 and the shielding cavity plate 72 are movably connected. The shielding assembly 7 is in contact with the shielding cavity plate 72. The shielding cavity plate 72 is provided with an injection channel and an exhaust port. The exhaust port is a one-way exhaust port. The inner cavity of the shielding cavity plate 72 is provided with a magnetically sensitive radiation shielding fluid.

[0037] The above scheme is adopted as follows: Through the design of the shielding component 7, the shielding cavity plate 72 is provided with an injection channel and an exhaust port, and the exhaust port is a one-way exhaust port. Magnetic radiation shielding fluid is placed inside the cavity of the shielding cavity plate 72. The magnetic radiation shielding fluid can effectively absorb and attenuate electromagnetic radiation, especially exhibiting superior shielding capability against electromagnetic waves of specific frequencies. The viscosity and composition of the fluid can be adjusted according to specific shielding requirements. When injecting the magnetic radiation shielding fluid, the fluid should have a low initial viscosity to ensure smooth filling of the complex cavity structure under injection pressure, avoiding flow restriction due to excessive viscosity. A low injection rate is used initially to allow the fluid to slowly fill the main channel, and then the pressure is gradually increased to accelerate the filling speed. A dynamic magnetic field is applied during the injection process, utilizing the magnetorheological effect of the magnetic fluid to guide the fluid preferentially towards... The fluid allows for flow in unfilled areas, reducing residual air bubbles in blind spots. Real-time monitoring of injection pressure and flow rate during injection allows for timely adjustments to the injection rate or pressure, preventing incomplete filling or structural damage due to excessive resistance. This adapts to different environments and radiation types. Compared to traditional solid materials, fluid construction is simpler, enabling rapid injection and curing, saving construction time. Compared to some easily aging materials, magnetically sensitive radiation shielding fluid is less prone to performance degradation under appropriate conditions. If the shielding wall is damaged, the fluid can be repaired on-site without completely replacing or dismantling the existing structure. The design of the mounting plate 71 slot and the shielding cavity plate 72 block makes installation of the mounting plate 71 and shielding cavity plate 72 more convenient, avoiding the time-consuming process of aligning them.

[0038] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the outer wall of the first decorative panel 1 is provided with a control panel, the connecting rope 426 is movably connected to the first decorative panel 1, the end of the control component 427 is provided with a slot, a pneumatic cylinder is provided between the moving component 52 and the fixed plate 51, a magnetic control block is provided between the fixed block 222 and the limiting block 223, a magnetic control block is provided on one side of the connecting plate 41, and the two magnetic control blocks attract each other.

[0039] The above scheme is adopted: through the design of the connecting rope 426 and the first decorative panel 1, and the design of the control panel on the outer wall of the first decorative panel 1, the fixing component 5 is controlled, so that the fixing component 5 can move up and down better, thereby better allowing the magnetic radiation shielding fluid in the shielding cavity plate 72 to flow. The viscosity and composition of the fluid can be adjusted according to specific shielding requirements, thus adapting to different environments and radiation types. The magnetic radiation shielding fluid can effectively absorb and attenuate electromagnetic radiation, especially showing superior shielding ability for electromagnetic waves of specific frequencies. Moreover, the fluid has no magnetic attraction when static, but exhibits strong magnetic properties when an external magnetic field is applied, and can form a dynamic arrangement structure in the magnetic field. When the radiation is constant, the traditional method generally requires a larger thickness as the radiation increases, leading to increased costs. However, the viscosity and composition of the magnetic radiation shielding fluid can be adjusted according to the magnitude of the radiation, without increasing the thickness of the wall, thus saving the cost of the wall. The connecting rope 426 and the first decorative panel 1 are connected. The decorative panel 1 is movable. When the connecting rope 426 is pulled, the first decorative panel 1 limits the connecting rope 426, making the connecting rope 426 more stable when moving. The design of the end slot of the control component 427 makes it easy to control the control component 427 by hand when the control component 427 is pulled to move the connecting rope 426. This allows for better control of the limiting unit 42, which in turn facilitates the connection with the connecting unit 22. This allows for faster dismantling or installation of the connection between the two walls, saving time in the installation or dismantling of the radiation-proof composite wall. The design of the pneumatic cylinder between the moving component 52 and the fixed plate 51 allows for better movement of the electric plate 53, enabling the magnetically sensitive radiation shielding fluid to better absorb and attenuate electromagnetic radiation. The design of the magnetic control loop between the connecting unit 22 and the second connecting plate 41 allows for better fixation of the connecting unit 22, making the connection between the connecting unit 22 and the second connecting plate assembly 4 more stable.

[0040] A construction process for a radiation-proof composite wall structure, applied to a radiation-proof composite wall structure, includes the following specific steps:

[0041] Step 1: Lay a shock-absorbing pad to reduce the interference of vibration on the precision shielding module;

[0042] Step 2: Erect formwork and tie prestressing tendons, pre-embed spiral pipes, and after pre-embedding, pour concrete for fixing component 5 to ensure the stability of fixing component 5.

[0043] Step 3: After the fixing component 5 is poured, install the support frame 6, then install the shielding component 7 in sequence, and finally install the first decorative panel 1, the first connecting plate assembly 2, the second decorative panel 3 and the second connecting plate assembly 4.

[0044] Step 4: When connecting the next radiation-proof composite wall, first connect the first connecting plate assembly 2 and the second connecting plate assembly 4, then support the formwork of the fixing assembly 5, tie the prestressed tendons, and then pour the concrete for the fixing assembly 5.

[0045] Step 5: After all modules are installed, close the valve at the bottom of the wall and inject heavy medium filler from the top to complete the installation of the radiation-proof composite wall.

[0046] Adjustment reference range of magnetically sensitive radiation shielding fluid under different radiation intensities

[0047] I. Gamma / X-ray Radiation Scenarios

[0048] Radiation intensity Proportion of high-Z shielding phase (tungsten / bismuth powder, 1~10μm) The proportion of the magnetically sensitive phase (carbonyl iron powder, 1~5μm) Base liquid type Initial viscosity (25℃, mPa·s) Low intensity (<10 μSv / h) 5%~15% 3%~8% Low viscosity silicone oil (100~500 cSt) 50~300 Medium intensity (10 μSv / h~10 mSv / h) 15%~35% 8%~15% Medium viscosity silicone oil / epoxy prepolymer 200~1500 High strength (>10 mSv / h) 35%~60% 15%~25% Low viscosity fluorocarbon liquid / epoxy reactive diluent 500~5000

[0049] Example of shielding effectiveness: A 1cm thick fluid can shield 80%, 85%, and 95% or more of typical γ / X-rays under low, medium, and high intensity conditions, respectively.

[0050] II. Neutron Radiation Scenarios

[0051] Radiation intensity Hydrogen-moderating phase (polyethylene / paraffin powder, 5~20μm) percentage <![CDATA[Proportion of thermal neutron capture phase (B₄C / samarium powder, 1~5μm)]]> <![CDATA[Proportion of magnetosensitive phase (nano Fe₃O₄)]]> Base liquid type Initial viscosity (25℃, mPa·s) Low strength (<10 N / cm²·s) 10%~20% 2%~5% 3%~8% Low viscosity silicone oil 50~400 <![CDATA[medium intensity (10~10 4 n / cm²·s)]]> 20%~40% 5%~15% 8%~12% Hydrofluorocarbon liquid / low viscosity epoxy 200~1500 <![CDATA[High strength (>10 4 n / cm²·s)]]> 40%~55% 15%~30% 12%~20% High hydrogen content polybutadiene solution 500~4000

[0052] Example of shielding effectiveness: For a 1cm thick fluid, the thermal neutron capture cross-section is >10 barn, >30 barn, and >50 barn under low, medium, and high intensities, respectively, and the fast neutron moderation rate is >70%, >85%, and >92%, respectively.

[0053] III. Microwave / Radio Frequency Electromagnetic Radiation Scenarios

[0054] Low strength (<1 mW / cm²) 3%~10% 5%~10% Low viscosity silicone oil 30~300 Medium strength (1 mW / cm²~10 W / cm²) 10%~30% 10%~18% Modified epoxy / fluorocarbon liquid 200~2000 High strength (>10 W / cm²) 30%~50% 18%~25% High-temperature resistant fluorocarbon liquid / polyimide prepolymer 500~5000

[0055] Example of shielding effectiveness: A 1cm thick fluid can achieve shielding effectiveness of 30~60 dB, 60~90 dB, and >90 dB in the 1~10 GHz frequency band, respectively.

[0056] Adjustment principles and precautions

[0057] 1. Total solids content control: The volume fraction of all shielding phases, magnetic sensitive phases and functional phases is ≤65% to avoid injection difficulties. In high-radiation scenarios, the volume fraction can be appropriately reduced by 5%~10% to add radiation stabilizers.

[0058] 2. The proportion of the magnetically sensitive phase should be 20% to 40% of the total solid phase, which ensures the magnetorheological effect without taking up too much space of the shielding phase.

[0059] 3. Particle size matching: The maximum particle size is ≤ 1 / 5 of the minimum cavity size. The combination of nano-sized and micro-sized particles improves suspension stability.

[0060] 4. Radiation stability: Rare earth stabilizers need to be added in high radiation environments to prevent degradation of the base liquid and demagnetization of magnetic particles.
