[0002] The functional zoning design of hospital inpatient buildings has a direct impact on the quality of medical services. Nursing stations play a crucial role as a vital hub connecting the medical team and patient services; their spatial organization, facility configuration, and construction and renovation methods must all strictly adhere to the professionalism and specificity of the medical environment.

[0003] However, given the unique nature of the hospital environment, stringent requirements exist for environmental pollution control during construction. Traditional nurse station renovations, using steel frame foundations, require extensive on-site welding and cutting, polluting the air and resulting in long renovation cycles and complex construction procedures. Furthermore, safety hazards are a significant bottleneck that traditional renovations struggle to overcome. On-site hot work requires special permits, and even with protective measures, fire risks cannot be completely eliminated. Additionally, traditional processes rely on manual on-site processing, and the quality of steel frame welding is significantly affected by the skill level of the workers.

[0004] Therefore, there is an urgent need for a steel-frame-free, fully prefabricated nursing station and its construction method to solve the above problems. Summary of the Invention

[0009] The frame structure includes multiple frame plates and multiple positioning pin assemblies. Blind hole positioning grooves are formed on the upper surface of each frame plate. Each positioning pin assembly includes a positioning base and a tapered guide head. The positioning base is embedded in the blind hole positioning groove, and the tapered guide head protrudes upward perpendicularly to the positioning base. A tenon is formed at the corresponding connection position between the skeleton structure and the frame plates. The tenon engages with the positioning pin assembly inserted into the frame plate. Medical device insertion holes are formed on the frame plates.

[0010] The operating platform is fixedly connected to multiple positioning pin assemblies installed on the top of the frame structure; the skeleton structure, the frame structure, and the operating platform are all made of integrated plates with anti-corrosion and flame-retardant properties.

[0011] Furthermore, an elastic buffer pad is provided inside the tenon; and / or,

[0012] An elastic cushioning pad is provided inside the concave slot.

[0013] Furthermore, the surface of the convex connector is provided with an anti-slip texture, and an adhesive layer is coated on the surface of the anti-slip texture.

[0014] Furthermore, the operating platform includes multiple artificial stone base layers, a corrosion-resistant and flame-retardant board layer is sandwiched between the operating platform and the frame structure, and an antibacterial coating is provided on the surface of the operating platform.

[0015] Furthermore, the edges of the artificial stone base layer are chamfered and seamlessly joined with the frame structure.

[0016] Furthermore, a stainless steel edge guard is installed at the edge of the operating platform, and the stainless steel edge guard is spliced ​​with the artificial stone base layer.

[0017] Furthermore, the frame structure includes multiple work areas, each work area including a storage component, which includes drawer-type cabinets and categorized storage compartments for classifying and retrieving items.

[0018] Furthermore, each of the categorized storage compartments is equipped with a cabinet door, and the cabinet door is connected to the categorized storage compartment via a damping hinge.

[0019] The construction method for a steel-frame-free, fully prefabricated nursing station, using any of the steel-frame-free prefabricated nursing stations described above, includes the following steps:

[0020] S1: According to the design drawings, the columns and beams in the skeleton structure, multiple frame plates in the frame structure, and the operating platform are prefabricated respectively; wherein, the columns are prefabricated with convex plugs, the two ends of the beams are pre-set with concave slots to match them, and the skeleton structure and the frame plates are provided with tenons at the corresponding connection positions; the columns and beams are both I-shaped cross-section structures optimized by finite element method; the frame plates are provided with blind hole positioning slots, and each blind hole positioning slot is pre-embedded with a positioning pin assembly;

During assembly, the columns and beams in the skeleton structure are connected by a convex connector and a concave slot, and axial preload is applied to the connection between the columns and beams by prestressed bolts. The convex connector and concave slot connection ensures that the beams are stably limited in multiple directions, enhancing their bending and torsional resistance.

The conical guide head of the positioning pin assembly enables automatic centering and guidance, assisting in positioning, reducing operational difficulty, and enabling rapid alignment and insertion between components. Furthermore, since all connecting structures are embedded inside the joints, the finished nurse station has no exposed protruding connectors or metal parts on the outside, achieving a concealed connection and forming a complete and continuous splice seam. All components can be prefabricated into standardized modules in the factory, making them lighter than traditional steel frames. On-site assembly is done in a modular fashion, significantly shortening the construction period. The overall structure can be assembled in a short time, making it suitable for rapid modifications in hospitals without interrupting operation, minimizing the impact on patients and doctors.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] Please refer to Figures 1 to 5As shown, this embodiment provides a steel frame-free prefabricated nursing station, including a skeleton structure 1, a frame structure 2, and an operating platform 3. The skeleton structure 1 includes columns 11, beams 12, and prestressed bolts 15. The columns 11 have convex connectors 13 at both ends, and the beams 12 have concave slots 14 at both ends corresponding to the convex connectors 13, allowing for a plug-in connection. Corresponding locations on both structures have through holes through which prestressed bolts 15 are inserted to apply axial preload to the connection between the columns 11 and beams 12. The frame structure 2 includes multiple frame plates 21 and multiple positioning pin assemblies 23. The upper surface of the frame plates 21 has... The blind hole positioning groove 22 and the positioning pin assembly 23 include a positioning base 231 and a conical guide head 232. The positioning base 231 is embedded in the blind hole positioning groove 22, and the conical guide head 232 protrudes upward perpendicular to the positioning base 231. The skeleton structure 1 and the frame plate 21 are provided with mortise and tenon grooves 24 at the corresponding connection positions. The mortise and tenon grooves 24 are connected with the positioning pin assembly 23 inserted on the frame plate 21. The frame plate 21 is provided with a medical device interface. The operating platform 3 is fixedly inserted into the multiple positioning pin assemblies 23 installed on the top of the frame structure 2. The skeleton structure 1, the frame structure 2 and the operating platform 3 are all made of integrated plates with anti-corrosion and flame-retardant properties.

[0040] With all components made of prefabricated panels, the entire structure does not use steel or welding processes, the entire installation process does not rely on heat processing, and open flame operations are completely eliminated, thus avoiding fire risks and making the construction site safer; no special work permits are required, saving time and costs; at the same time, all materials in the nurse station are integrated panels with anti-corrosion and flame-retardant properties, which can effectively reduce the risk of fire in high-temperature environments.

[0041] During assembly, the columns 11 and beams 12 in the frame structure 1 are connected by a convex connector 13 and a concave slot 14. Axial preload is then applied to the connection between the columns 11 and beams 12 using prestressed bolts 15. The nested geometric constraint between the convex connector 13 and the concave slot 14 provides greater resistance to lateral shear than simple surface contact or direct bolt connection. The plug-in connection ensures that the beams 12 are stably confined in multiple directions, enhancing their bending and torsional resistance. The prestressed bolts 15 provide continuous axial preload, ensuring a tight fit between the convex connector 13 and the concave slot 14, effectively preventing structural displacement or deformation due to loosening during long-term use, eliminating gaps, and improving overall rigidity. The frame plate 21 is embedded with a positioning pin assembly 23, and the connection position between the skeleton structure 1 and the frame plate 21 is provided with a tenon 24. The conical guide head 232 of the positioning pin assembly 23 realizes automatic centering guidance, assists in positioning, reduces the difficulty of operation, greatly reduces manual adjustment errors, improves assembly accuracy and consistency, realizes rapid alignment and insertion between various components, reduces on-site measurement and leveling time, and since each connecting structure is embedded inside the splice, the finished nurse station after assembly has no exposed convex plugs 13 or metal parts on the outside, realizing a hidden connection, forming a complete and continuous splice, with a flat and undamaged appearance; all components can be prefabricated into standardized modules in the factory, which are lighter than traditional steel frames, and only require building block-style assembly on site, greatly shortening the construction period.

[0042] Prefabricated components are assembled on-site, eliminating the need for wet work (such as cast-in-place concrete) and welding, resulting in no dust, oil stains, or wastewater. The assembly process involves mechanical connections or snap-fits, generating no construction waste. After disassembly or modification, the components can be recycled, making it green and environmentally friendly.

[0043] The steel-frame-free prefabricated nursing station can be assembled in a short time, making it suitable for hospitals to quickly modify without interrupting operation, reducing the impact on patients and doctors. The material used is integrated board with anti-corrosion and flame-retardant properties, meeting the hospital's requirements for durability, fire resistance, moisture resistance, and easy cleaning. Sockets can be reserved according to the location of medical equipment interfaces to support quick access and improve the flexibility of equipment layout.

[0044] For example, the skeleton structure 1 and the frame structure 2 can be made of 18 mm thick anti-corrosion and flame-retardant board, wherein the material of the anti-corrosion and flame-retardant board can be, but is not limited to, phenolic resin board.

[0045] like Figure 4As shown, in some optional embodiments, an elastic buffer pad 5 is provided in the tenon 24; and / or, an elastic buffer pad 5 is provided in the concave slot 14; wherein, the elastic buffer pad 5 is used to buffer the contact impact between structural components during assembly, which can effectively eliminate the rigid collision noise generated when metal parts are connected, and avoid noise interference with the normal operation of the hospital and the rest of patients; at the same time, the elastic buffer pad 5 can appropriately compensate for local construction errors in the pre-tightened connection state, enhance the fit and stability of the connection structure, thereby improving the seismic resistance and vibration resistance of the overall structure.

[0046] Optionally, the elastic cushioning pad 5 may be, but is not limited to, a rubber pad, and no specific limitation is made here.

[0047] like Figure 3 As shown, in some optional embodiments, the surface of the convex connector 13 is provided with an anti-slip texture, and an adhesive layer is coated on the surface of the anti-slip texture. The anti-slip texture is used to enhance the surface friction when the convex connector 13 and the concave slot 14 are inserted and mated, preventing them from sliding or loosening. The adhesive layer is used to fill the small splicing gaps and improve the connection sealing and fit. The combination of the two can effectively eliminate the assembly gaps at the structural insertion points and improve the connection accuracy and overall stability.

[0048] It is understood that the adhesive layer may, but is not limited to, using epoxy resin adhesive, and no specific limitation is made here.

[0049] like Figure 1 As shown, specifically, the operating platform 3 includes multiple artificial stone base layers. A corrosion-resistant and flame-retardant board layer is sandwiched between the operating platform 3 and the frame structure 2, and the surface of the operating platform 3 is coated with an antibacterial coating. Artificial stone is characterized by high strength, wear resistance, impact resistance, and high surface hardness, making it suitable for scenarios involving frequent contact, placement of equipment, or operation. Compared to natural stone, artificial stone can be customized, has uniform quality, and controllable cost; therefore, using an artificial stone base layer can improve load-bearing capacity and durability. The corrosion-resistant and flame-retardant board layer sandwiched between the operating platform 3 and the frame structure 2 effectively blocks corrosion and heat conduction from the frame structure 2 to the operating platform 3, increasing the overall service life of the operating platform 3 and improving the fire resistance of the work surface. In public buildings such as hospitals, it can effectively curb the spread of fire and improve the fire resistance rating of the structure itself. The antibacterial coating on the surface of the artificial stone base layer inhibits the growth and spread of bacteria and viruses, meeting the high standards of cleaning and disinfection required by hospitals, reducing the risk of cross-infection, and improving the overall safety and hygiene of the usage environment.

[0050] The antibacterial coating may, but is not limited to, using an antibacterial resin coating, with a thickness of 3 mm or more.

[0051] Furthermore, the edges of the artificial stone base layer are chamfered and seamlessly spliced ​​with the frame structure 2, which can effectively prevent dust and liquid from accumulating in the gaps and avoid bacterial growth in dead corners. At the same time, it can also ensure that the work surface and the frame structure 2 have a smooth transition without steps or height differences.

[0052] For example, the edges of the artificial stone base layer are chamfered at 45°, and the edges connecting the frame structure 2 and the artificial stone are also chamfered at 45° accordingly, so that the two can be seamlessly spliced.

[0053] like Figure 1 As shown, due to the frequent use of alcohol and disinfectants in medical settings, and the high humidity, the exposed edges of artificial stone may become contaminated or age due to capillary absorption of liquids. To address these issues and prevent liquids such as disinfectants or medications from penetrating into the structure, decorative components are installed along the edges of the operating platform 3. These components are stainless steel edge protectors 31, which are spliced ​​with the artificial stone base layer. Stainless steel has excellent corrosion resistance, impermeability, and mildew resistance, protecting the edges of the artificial stone base layer from liquid erosion. Furthermore, the stainless steel edge protector 31 has a smooth surface, making it easy to wipe and disinfect, and it does not breed bacteria, making it particularly suitable for nurse station areas with high cleanliness requirements.

[0054] For example, the stainless steel edge protector 31 may be glued to the edge of the operating platform 3 by means of an edge wrapping method.

[0055] like Figure 2 As shown, since the nurse station stores different types of medical consumables and registration supplies, it is necessary to classify and place each category separately. In some embodiments, the frame structure 2 includes multiple work areas, each work area including a storage component 4. The storage component 4 includes drawer-type cabinets and classified storage compartments for classifying and retrieving items. Drawer-type cabinets are suitable for storing frequently used items, which can be pulled out and retrieved immediately after use, making operation convenient. Classified storage compartments can be meticulously divided for different types of labels, medicines, instrument accessories, etc., to avoid mixing, loss, or misuse. Reasonable storage space can reduce search time and improve the continuity and efficiency of nurses' daily operation procedures.

[0056] Furthermore, each categorized storage compartment is equipped with a cabinet door, which is connected to the categorized storage compartment by a damping hinge. The damping hinge can form a buffer at the end of the cabinet door when it is closed, avoiding noise when the cabinet door is closed. This is suitable for areas with strict requirements for a quiet environment, such as hospital nurse stations and ward entrances, and helps to avoid disturbing patients' rest and improve the overall comfort of the medical environment.

[0057] This embodiment also provides a construction method for a steel-frame-free, fully prefabricated nurse station, which adopts the steel-frame-free prefabricated nurse station in any of the above embodiments, including the following steps:

[0058] S1: According to the design drawings, prefabricate the columns 11 and beams 12 in the skeleton structure 1, multiple frame plates 21 in the frame structure 2, and the operating platform 3 respectively; wherein, the columns 11 are prefabricated with convex plug joints 13, the beams 12 are pre-set with concave slots 14 at both ends to match them, and the skeleton structure 1 and the frame plates 21 are provided with tenons 24 at the corresponding connection positions; the columns 11 and beams 12 are both I-shaped cross-section structures designed by finite element optimization; blind hole positioning slots 22 are provided on the frame plates 21, and positioning pin assemblies 23 are pre-embedded in each blind hole positioning slot 22.

[0059] S2: Transport the above-mentioned prefabricated structural components to the construction site and prepare for assembly construction;

[0060] S3: Conduct benchmark positioning and layout at the construction site. First, install column 11 and fix it vertically in the predetermined installation position.

[0061] S4: The frame plate 21 with positioning pin assembly 23 is inserted into the pre-set tenon groove 24 on the skeleton structure 1 through the conical guide head 232 of positioning pin assembly 23, so as to realize the initial alignment and positioning connection between the skeleton structure 1 and the frame plate 21.

[0062] S5: Subsequently, the concave slot 14 of the crossbeam 12 is inserted into the convex connector 13 of the installed column 11, and the prestressed tie bolt 15 is inserted into the through hole of the insertion part. By tensioning the prestressed tie bolt 15, a stable connection with prestress is formed between the column 11 and the crossbeam 12, thereby completing the construction of the overall load-bearing frame structure 2.

[0063] S6: Hoist the operating platform 3 according to the preset number sequence, and connect it to the multiple positioning pin components 23 set on the top of the frame structure 2 to complete the stable installation of the operating platform 3.

[0064] The construction method for a steel-frame-free, fully prefabricated nurse station involves the following steps during assembly: The uprights 11 and beams 12 in the frame structure 1 are connected via a convex connector 13 and a concave slot 14. Axial preload is applied to the connection between the uprights 11 and beams 12 using prestressed bolts 15. The nested geometric constraint between the convex connector 13 and the concave slot 14 provides greater resistance to lateral shear than simple surface contact or direct bolt connection. The plug-in connection ensures the beams 12 are stably confined in multiple directions, enhancing their bending and torsional resistance. The prestressed bolts 15 provide continuous axial preload, ensuring a tight fit between the convex connector 13 and the concave slot 14, effectively preventing structural displacement or deformation due to loosening during long-term use, eliminating gaps, and improving overall rigidity. The frame plate 21 is embedded with a positioning pin assembly 23, and the connection position between the skeleton structure 1 and the frame plate 21 is provided with a tenon 24. The conical guide head 232 of the positioning pin assembly 23 realizes automatic centering guidance, assists in positioning, reduces the difficulty of operation, greatly reduces manual adjustment errors, improves assembly accuracy and consistency, realizes rapid alignment and insertion between various components, reduces on-site measurement and leveling time, and since each connecting structure is embedded inside the splice, the finished nurse station after assembly has no exposed convex plugs 13 or metal parts on the outside, realizing a hidden connection, forming a complete and continuous splice, with a flat and undamaged appearance; all components can be prefabricated into standardized modules in the factory, which are lighter than traditional steel frames, and only require building block-style assembly on site, greatly shortening the construction period.

[0065] After testing and verification, the steel-frame-free, fully prefabricated nursing station, in a pilot project involving the construction of 40 nursing stations, reduced the total construction period by 672 hours; the assembly cycle for a single nursing station was reduced from 72 hours using traditional welding methods to only 6 hours, increasing assembly efficiency by over 91%; on-site welding and hot work were eliminated throughout the process, significantly reducing construction safety hazards and the risk of accidents by 92%; due to the factory prefabrication and on-site assembly methods, the construction environment was greatly improved, with dust emissions decreasing from 3.2 mg / m³ to 0.35 mg / m³, a reduction of 89%; environmentally friendly solvent-free adhesives were used, with low volatile organic compounds (VOCs). The release of organic compounds is 0.04 mg / m³, which is more than 50% better than the national standard limit. In this project, the amount of construction waste is reduced by 128 tons (total of 40 sites), effectively reducing on-site construction pollution. In terms of material costs, each nurse station can eliminate the use of approximately 280 kg of steel frame, reducing steel consumption, reducing floor load, and further reducing structural burden. Through standardized component production and modular design, the dimensional qualification rate of all components reaches 100%, effectively reducing on-site adjustments and rework rates. At the same time, due to the absence of welds, corrosion resistance, and coating requirements, the maintenance cost throughout its entire life cycle is significantly reduced, demonstrating good economic efficiency and sustainability.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.

S4: The frame plate (21) equipped with the positioning pin assembly (23) is inserted into the pre-set tenon (24) on the skeleton structure (1) through the tapered guide head (232) of the positioning pin assembly (23), so as to achieve the initial alignment and positioning connection between the skeleton structure (1) and the frame plate (21). S5: Subsequently, the concave slot (14) of the crossbeam (12) is inserted into the convex connector (13) of the installed column (11), and the prestressed bolt (15) is inserted into the through hole of the insertion part. By tensioning the prestressed bolt (15), a stable connection with pre-tension is formed between the column (11) and the crossbeam (12), thereby completing the construction of the overall load-bearing frame structure. S6: Hoist the operating platform (3) according to the preset number sequence, and connect it to the multiple positioning pin components (23) set on the top of the frame structure (2) to complete the stable installation of the operating platform (3).
