Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, and in particular relates to a radiation-proof building structure for a medical operating room. Background Technology

[0002] As a crucial technical department in hospitals, the operating room undertakes the critical task of providing surgery and emergency care for patients. With the rapid development of medical technology, the use of intraoperative radiological examinations to assist surgical treatment has become increasingly common. These medical devices generate a large amount of radiation during use, and the radiation energy has strong penetrating power. Without effective protection, it can easily penetrate walls and cause radiation hazards to people outside the operating room.

[0003] Currently, the common practice for radiation protection in operating rooms is to install lead plates. However, lead plates alone offer limited protection and are insufficient to fully withstand the high-intensity radiation generated by medical equipment. Furthermore, existing radiation-proof wall structures suffer from overall instability. For example, the connection strength between some prefabricated lead plate welded partitions and the main structure is difficult to guarantee. In the densely populated hospital environment, they are at high risk of deformation and displacement due to compression. Moreover, construction quality is significantly affected by human factors, and weld seams are prone to cracking, leading to radiation leakage. In addition, existing technologies lack reliable radiation protection solutions for locations such as water pipes, air ducts, and switch boxes, also posing potential radiation leakage risks. Regarding wall cleaning and maintenance, residues easily form on the surface of some existing structures during disinfection, making cleaning difficult and hindering the maintenance of a sterile environment in the operating room. Therefore, developing a new type of radiation-proof wall structure for medical operating rooms to improve radiation protection, enhance structural stability, and facilitate cleaning and maintenance is of significant practical importance and urgent need. Summary of the Invention

[0004] This utility model provides a radiation protection building structure for medical operating rooms, aiming to solve the problems of poor radiation protection effect, unstable structure, and difficulty in cleaning of existing radiation protection building structures for medical operating rooms.

[0005] To achieve the above objectives, this utility model provides a radiation-proof building structure for a medical operating room, including a floor, ceiling, and side walls constituting the structure of the operating room. The side walls include a civil engineering wall and an internal composite isolation layer. The internal composite isolation layer includes an electrolytic steel plate layer, a calcium carbonate board layer, and a support frame. The electrolytic steel plate layer is attached to the calcium carbonate board layer. The support frame is used to support the composite structure composed of the electrolytic steel plate layer and the calcium carbonate board layer. From the inside to the outside, the side walls consist of an electrolytic steel plate layer, a calcium carbonate board layer, a support frame, and a civil engineering wall.

[0006] Preferably, it also includes a sidewall lead plate protective layer disposed on the outside of the civil engineering wall, the sidewall lead plate protective layer being fixed by a keel and extending from the floor to the ceiling.

[0007] Preferably, the operating room building structure includes several inner rooms, and the inner rooms are separated by partition walls. The partition walls include two opposing internal composite isolation layers, and a lead plate protective layer is provided between the internal composite isolation layers.

[0008] Preferably, the lead plate protective layer of the partition wall is fixed by a support frame, and when the support frame is connected to the lead plate protective layer of the partition wall by self-tapping screws, a steel strip is set in the middle as a gasket.

[0009] Preferably, the electrolytic steel plate layer and calcium carbonate plate layer of the internal composite isolation layer extend to the ceiling, and the ceiling also includes a ceiling lead plate and a top plate. The ceiling, from bottom to top, includes an electrolytic steel plate layer, a calcium carbonate plate layer, a support frame, a ceiling lead plate, and a top plate.

[0010] Preferably, the electrolytic steel plate layer has a rounded chamfer in the transition area between the side wall and the ceiling.

[0011] Preferably, the floor includes an antistatic rubber layer, a barium sulfate layer, and a structural floor slab arranged from top to bottom. The antistatic rubber layer is laid to the side wall and continues to extend upward to form a skirting board. The angle at which the antistatic rubber layer transitions from the floor to the side wall is a rounded chamfer.

[0012] Preferably, the floor also includes a PVC flooring material laid on top of the antistatic rubber layer. The PVC flooring material is laid to the side wall and then extends upward to form a skirting board. The angle from the floor to the side wall of the PVC flooring material is a rounded chamfer. The edge of the PVC flooring material is sealed and fixed by an aluminum alloy strip.

[0013] Preferably, the support frame is composed of galvanized square steel, which is fixed to each other by welding, and the galvanized square steel is fixed to the ceiling and floor by anchor bolts. The edge of the electrolytic steel plate layer is fixed to the support frame by welding, and the middle part of the electrolytic steel plate layer is fixed to the support frame by lead-coated steel nails.

[0014] Preferably, the gaps in the sidewall and ceiling areas, as well as the gaps between the sidewall and the ceiling, are all sealed with weather-resistant sealant.

[0036] Example 1

[0037] like Figure 1-4As shown, this embodiment provides a radiation-proof building structure for a medical operating room, including a floor, ceiling, and side walls that constitute the structure of the operating room. The side walls include a civil engineering wall and an internal composite isolation layer. The internal composite isolation layer includes an electrolytic steel plate layer, a calcium carbonate board layer, and a support frame. The electrolytic steel plate layer is attached to the calcium carbonate board layer. The support frame is used to support the composite structure composed of the electrolytic steel plate layer and the calcium carbonate board layer. The side walls, from the inside out, are the electrolytic steel plate layer, the calcium carbonate board layer, the support frame, and the civil engineering wall.

[0038] This radiation-shielding building structure encompasses the floor, ceiling, and side walls that make up the operating room's structure. This incorporates the entire perimeter of the operating room space into the radiation-shielding system, ensuring effective blocking of radiation from all directions and creating a relatively enclosed radiation-shielding space to protect the safety of personnel outside the operating room. The side walls, as a crucial part of the radiation shielding, consist of a structural wall and an internal composite insulation layer. The structural wall is a traditional building wall, providing basic spatial division and structural support; while the internal composite insulation layer is the core component that achieves the radiation-shielding function.

[0039] An electrolytic steel plate layer is bonded to a calcium carbonate plate layer. The electrolytic steel plate has excellent radiation shielding properties, effectively blocking radiation penetration from medical equipment and serving as the first critical barrier against radiation. The calcium carbonate plate layer is tightly bonded to the electrolytic steel plate layer, providing protection against damage from external impacts and friction. The calcium carbonate plate also possesses physical strength and stability, contributing to the overall integrity and durability of the composite structure. A support frame supports the composite structure formed by the electrolytic steel plate layer and the calcium carbonate plate layer, providing a stable support framework for the entire internal composite isolation layer. This ensures that the layers maintain a relatively stable position during use, preventing misalignment due to external forces that could compromise the radiation shielding effect.

[0040] The support frame is composed of galvanized square steel, which is fixed together by welding. The galvanized square steel is fixed to the ceiling and floor by anchor bolts. The edges of the electrolytic steel plate layer are fixed to the support frame by welding, and the middle part of the electrolytic steel plate layer is fixed to the support frame by lead-coated steel nails.

[0041] The galvanizing process forms a dense zinc coating on the surface of the square steel, effectively preventing rust and corrosion, improving its durability and service life, and making it suitable for the relatively humid, clean, and frequently disinfected environment of the operating room. The galvanized square steel is fixed to the ceiling and floor with anchor bolts that penetrate deep into the structure, firmly connecting the support frame to the main building structure. This further enhances the overall integrity of the radiation shielding structure and the operating room building, ensuring its stability during long-term use and resisting various forces encountered in daily life. The middle section of the electrolytic steel plate layer is fixed to the support frame with lead-coated steel nails. These nails not only secure the electrolytic steel plate layer to the support frame but also, to some extent, enhance the radiation shielding capability at the fixing points, preventing radiation leakage due to gaps in the fixing points.

[0042] The gaps in the side walls and ceiling areas, as well as the gaps between the side walls and the ceiling, are all sealed tightly with weather-resistant sealant. This sealant possesses excellent elasticity, weather resistance, and sealing properties, adapting to temperature changes and minor structural deformations while maintaining a consistent seal. By filling these gaps, radiation leakage is effectively prevented, further enhancing the overall airtightness of the radiation-proof building structure and ensuring optimal radiation protection performance in the operating room. It also prevents dust, moisture, and bacteria from entering through the gaps, maintaining a clean environment in the operating room.

[0043] Example 2

[0044] In this embodiment, a sidewall lead plate protective layer is also included, which is fixed by a keel and extends from the floor to the ceiling.

[0045] This embodiment, based on the original radiation-proof building structure of a medical operating room, adds a lead plate protective layer to the side walls to further enhance radiation protection performance. Lead has excellent radiation-proof properties and can effectively block the penetration of radiation such as X-rays. The lead plate protective layer on the outside of the building wall forms an additional radiation protection barrier. Working in synergy with the internal composite isolation layer, it greatly enhances the radiation blocking effect of the side walls, further protecting personnel outside the operating room from radiation hazards.

[0046] The lead plate protective layer on the side wall is fixed with a keel, which acts as a supporting structure, providing a stable installation base for the lead plate. This fixing method not only facilitates the installation and removal of the lead plate, making subsequent maintenance and repair easier, but also ensures that the lead plate remains flat during use, preventing deformation or displacement due to external forces, thus ensuring the stable performance of its radiation protection function. The use of the keel effectively connects the lead plate protective layer to the civil wall, enhancing the integrity and stability of the entire side wall structure.

[0047] Furthermore, the lead plate protective layer on the side walls extends from the floor to the ceiling, achieving full coverage of side wall protection. This continuous protective design avoids the potential for radiation leakage caused by discontinuities in the protective layer, ensuring that radiation is effectively blocked throughout the entire side wall area, leaving no blind spots. Whether near the operating room floor or close to the ceiling, radiation cannot easily penetrate the side walls, thus constructing a comprehensive and seamless side wall radiation protection system, creating a safer environment for the operating room.

[0048] Example 3

[0049] like Figure 8 As shown in this embodiment, the operating room building structure includes several inner rooms, with partition walls between the inner rooms. The partition walls include two opposing internal composite isolation layers, with a lead plate protective layer between the internal composite isolation layers.

[0050] In this radiation-proof building structure for the medical operating room, the overall structure of the operating room building includes multiple inner rooms, which may serve different functions, such as surgical operation areas and instrument preparation areas. Since medical equipment generates radiation when used in different inner rooms, the partition walls between the inner rooms must also have good radiation protection performance to prevent radiation from spreading between the inner rooms and to ensure the safety of medical staff and patients in each area.

[0051] This application employs a partition wall design between the interior rooms, comprising two opposing internal composite isolation layers and a lead plate protective layer sandwiched in between. The internal composite isolation layers consist of an electrolytic steel plate layer, a calcium carbonate plate layer, and a supporting frame. As previously mentioned, the electrolytic steel plate layer effectively blocks radiation, the calcium carbonate plate layer protects the electrolytic steel plate and enhances structural stability, and the supporting frame provides support for the entire composite structure. The lead plate protective layer, leveraging lead's excellent radiation-shielding properties, further strengthens the partition wall's radiation-blocking capability.

[0052] Two opposing internal composite isolation layers, working in conjunction with the intermediate lead plate protective layer of the partition wall, form a "sandwich"-like composite radiation protection structure. When radiation penetrates the partition wall between the inner rooms, it first encounters the internal composite isolation layer on one side. The electrolytic steel plate layer within absorbs and blocks most of the radiation. The remaining small amount of penetrating radiation then encounters the lead plate protective layer of the partition wall. The lead plate, due to its inherent properties, further significantly weakens the radiation. Finally, even if a very small amount of radiation still penetrates the lead plate, it must pass through the internal composite isolation layer on the other side. This multi-layered protection design greatly reduces the possibility of radiation propagation between the inner rooms, effectively ensuring a relatively independent and safe environment for each inner room, and meeting the stringent radiation protection requirements of the complex functional zoning of the operating room.

[0053] Example 4

[0054] like Figure 9As shown, in this embodiment, the lead plate protective layer of the partition wall is fixed by a support frame. When the support frame is connected to the lead plate protective layer of the partition wall by self-tapping screws, a steel strip is set in the middle as a gasket.

[0055] The method of fixing the lead plate protective layer in the partition wall directly affects its radiation protection performance and structural stability. The support frame, as the main connecting element, provides reliable support for the lead plate protective layer, ensuring its stability during use and preventing displacement or deformation due to external impacts, personnel activity, or other factors that could affect the radiation protection effect. It also facilitates maintenance or replacement.

[0056] When connecting self-tapping screws to the lead plate protective layer of the partition wall, steel strips are used as washers. This design serves two purposes: firstly, the hard, flat steel strips effectively distribute the pressure generated when tightening the self-tapping screws, preventing the lead plate from denting or breaking due to excessive localized stress. Secondly, the steel strips increase the contact area between the support frame and the lead plate protective layer, making the connection tighter and more uniform, further enhancing the stability of the overall structure. In addition, the steel strips also play a certain positioning role, ensuring the accurate positioning of the lead plate protective layer during installation, neat splicing of each part, and preventing gaps.

[0057] Example 5

[0058] like Figure 2 As shown, in this embodiment, the electrolytic steel plate layer and calcium carbonate plate layer of the internal composite isolation layer extend to the ceiling, and the ceiling also includes a ceiling lead plate and a top plate. The ceiling, from bottom to top, includes an electrolytic steel plate layer, a calcium carbonate plate layer, a support frame, a ceiling lead plate, and a top plate.

[0059] In the radiation protection building structure of medical operating rooms, the electrolytic steel plate layer of the internal composite isolation layer extends to the ceiling, closely cooperating with the ceiling structure to further improve the radiation protection system. The ceiling consists of an electrolytic steel plate layer, a support frame, a ceiling lead plate, and a top plate from bottom to top. This layered structure achieves multiple layers of radiation protection.

[0060] The functions of the electrolytic steel plate layer, calcium carbonate plate layer, support frame, and lead plate have been described previously and will not be repeated here. It should be noted that the electrolytic steel plate layer of the ceiling is connected to the electrolytic steel plate layer of the side walls, forming a continuous radiation-shielding surface within the operating room space, reducing the risk of radiation leakage caused by structural discontinuities. Furthermore, the ceiling support frame and the side wall support frames are at least partially continuous or shared, which also contributes to the overall structural stability.

[0061] As the outermost layer of the ceiling structure, the top plate protects the internal radiation shielding components and enhances the overall structural strength of the ceiling, resisting the impact of external environmental factors on the internal structure.

[0062] In a preferred embodiment, the transition area between the electrolytic steel plate layer and the side walls and ceiling is rounded. The rounded corners avoid gaps and dead angles that may exist in right-angle transitions, preventing radiation leakage from these areas and further ensuring the integrity of radiation protection. From the perspective of operating room environmental maintenance, the rounded corners facilitate cleaning and disinfection. Operating rooms require a high degree of cleanliness; right-angled areas are prone to dust and dirt accumulation, while the rounded corners, without sharp edges, are more convenient to clean with cleaning tools or for disinfection, reducing the likelihood of residue and bacteria remaining. This helps maintain a sterile environment in the operating room, reduces the risk of infection, and meets the high hygiene standards required for operating rooms.

[0063] Example 6

[0064] like Figure 4 As shown, in this embodiment, the floor includes an antistatic rubber layer, a barium sulfate layer, and a structural floor slab arranged from top to bottom. The antistatic rubber layer is laid to the side wall and continues to extend upward to form a skirting board. The angle from the floor to the side wall of the antistatic rubber layer is a rounded chamfer.

[0065] The antistatic rubber layer, as the top layer of the floor, primarily functions to prevent the generation of static electricity. Simultaneously, the rubber material offers excellent wear resistance and slip resistance, providing a safe walking environment for medical staff and patients. After being laid to the side walls, the antistatic rubber layer extends upwards to form a skirting board, not only protecting the bottom of the side walls from impacts and wear but also further enhancing the overall seal, reducing the possibility of dust and debris entering through the gaps between the floor and the side walls. The rounded corner design facilitates cleaning and disinfection, preventing dirt and grime from accumulating at right angles.

[0066] The barium sulfate layer has excellent radiation protection properties, capable of absorbing and blocking radiation, and is a key component of floor radiation protection. The structural floor slab is the original basic structure of the floor, providing load-bearing support.

[0067] like Figure 5-7 As shown, in some other embodiments, the flooring also includes a PVC flooring material laid on top of an antistatic rubber layer. The PVC flooring material extends upwards from the side wall to form a skirting board. The angle at which the PVC flooring material transitions from the floor to the side wall is a rounded chamfer. The edges of the PVC flooring material are sealed and fixed with aluminum alloy strips. PVC flooring material is characterized by its soft texture, rich colors, and aesthetic appeal and durability. The aluminum alloy strips, being hard and corrosion-resistant, not only firmly fix the edges of the PVC flooring material and improve sealing, preventing warping and deformation, but also serve a decorative purpose, making the junction between the floor and the side wall neater and more aesthetically pleasing.
