Description

Technical Field

[0001] This invention relates to a construction process for installing lead plates on the walls and ceilings of radiation protection projects in radiomedical facilities. Background Technology

[0002] With the increasingly widespread application of radiation technology in the medical field, radiation protection engineering is receiving more and more attention. However, traditional methods have many problems. To address the shortcomings of existing technologies, we researched and developed a new technology, compiled it into a construction method, and applied for a patent on April 20, 2023, with patent application number CN202310425997.4, entitled "A Method for Installing Lead Plates in Radiation Protection Engineering for Radiation Protection Rooms in Radiation Medicine" (hereinafter referred to as the "previous patent"). The construction method itself was approved by Zhejiang Province in September 2023. Further research revealed that radiation medicine rooms have different construction conditions in practice, necessitating the development of corresponding technologies to meet the needs of these diverse conditions.

[0003] The difference between this patent and the previous patent: The previous patent mainly addressed situations where the structural height of a radiology room exceeds 4.5m and the lead plate thickness is less than or equal to 3mm (i.e., thin lead plate). In these cases, there was space above the ceiling for constructing a lightweight steel bracket, which saved on lead plate usage. Based on the physical properties of thin lead plates, auxiliary plywood was cleverly used to install the lead plates on the walls, and the lightweight steel bracket was used to lay the lead plates on the ceiling, creatively solving the lead plate installation problem in radiation protection engineering for radiology rooms. This patent mainly addresses situations where the lead plate thickness is greater than 3mm (i.e., thick lead plate), the structural height of a radiology room is less than 4.5m, there is no space above the ceiling for constructing a lightweight steel bracket, and the physical properties of the lead plate change when the thickness exceeds 3mm. The solution proposed in the previous patent is no longer suitable for the new requirements. Therefore, a new technical solution was developed to specifically address the installation of thick lead plates on walls and ceilings. The lead plate installation methods for radiation protection engineering provided by the two patents are completely different.

[0004] As national and industry design standards further tighten radiation protection requirements, demanding thicker lead plates, more stringent radiation protection measures, and more complex and demanding installation of lead plates, this patent will undoubtedly see wider application. Furthermore, with the accelerated pace of medical equipment upgrades and the gradual obsolescence of traditional radiology facilities necessitating renovation and expansion, this patent is particularly applicable to such renovation and expansion projects. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention aims to provide a construction process for installing lead plates on the walls and ceilings of radiation protection projects in radiology facilities. This process is suitable for medical facilities with lead plate thicknesses greater than 3mm, a structural height less than 4.5m, and no space above the ceiling for constructing lightweight steel brackets, as well as for the renovation and expansion of radiology facilities. Using this patented technology for installing lead plates on the walls and ceilings of radiation protection projects offers advantages such as reliable and comprehensive radiation protection, convenient and efficient installation, cost savings, and standardized quality control. It effectively avoids rework and significant increases in final costs, solving a series of problems associated with traditional methods.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for installing lead plates on the walls and ceilings of radiation protection engineering in radiology rooms. This method is implemented after the main structure of the radiology room is completed, secondary structural wall plastering is finished, the technical parameters of the medical equipment and the on-site handling and hoisting plan are clarified, professional construction drawings are handed over and reviewed, and on-site handover and acceptance are carried out. The method is characterized by the following steps:

[0007] 1) Inspect, verify, and clean the base of the walls and ceiling;

[0008] 2) On-site layout and layout to determine the positions of the longitudinal and transverse keels and their installation sequence;

[0009] 3) A “top-to-bottom” light steel frame is designed for the decorative wall panel, and the embedded parts of the steel structure foundation and the embedded parts of the medical equipment gantry / rail foundation are installed first.

[0010] 4) Install the keel for the lead plates on the walls and ceiling according to the layout and positioning in step 2);

[0011] 5) Detail treatment of wall and ceiling joints;

[0012] 6) Install lead plates on the walls and ceiling in sequence, either manually or with auxiliary equipment, while simultaneously installing cables and pipes on the ceiling and other supporting works.

[0013] 7) An additional layer of cover plate is required at the longitudinal and transverse joints of the lead plates on the walls and ceiling;

[0014] 8) Strengthen the protection of detailed nodes, and patch or "wrap nail heads" wherever there are nail heads or holes;

[0015] 9) Special acceptance inspection of lead plate installation;

[0016] 10) Fabrication and installation of "sky-high and ground-level" steel frames; fabrication and installation of steel supports for medical equipment pylons and rails; welding of ceiling hangers.

[0017] 11) Construction of wall paneling and light steel keel ceiling finishing.

[0018] Furthermore, the lead plate is thicker than 3 mm.

[0019] Furthermore, the detailed treatment of wall and ceiling nodes in steps 5) and 8) includes door and window openings, louvers, holes, slots, pipeline locations, post-embedded parts of the light steel frame foundation, and post-embedded parts of the medical equipment pendant tower / rail steel support foundation.

[0020] Furthermore, during step 6), the installation of lead plates on the walls and ceiling is carried out simultaneously with the installation of supporting works such as cables and pipes on the suspended ceiling. These supporting works include: air conditioning system, fresh air system, medical equipment pendant / rail, exhaust fan ventilation ducts, cable trays, distribution boxes, and fire protection facilities.

[0021] Furthermore, in step 7), an additional layer of cover lead plate is required at the longitudinal and transverse splicing joints of the lead plates on the wall and ceiling to prevent radiation from leaking from the splicing joints; the width of the cover lead plate is 80-100mm, and the nail heads are "wrapped" during installation; the fixing strip of the additional lead plate on the wall is made of flat iron, and the fixing strip of the additional lead plate on the ceiling is made of steel square tube.

[0022] Furthermore, the auxiliary equipment is used for automatically laying lead plates. The auxiliary equipment includes a mobile frame, a guide rod on the mobile frame, and a mobile platform on the guide rod. The mobile platform is equipped with a lifting component that drives the mobile platform to move up and down along the guide rod. The mobile platform is equipped with a lead plate fixing component that fixes the lead plate to the wall keel frame and / or the ceiling keel frame. The lead plate fixing component is equipped with a flipping mechanism, which is used to flip the lead plate fixing component to achieve switching between the two states of ceiling laying and wall laying. The mobile platform is also equipped with a pushing component, which is used to push the lead plate fixing component to move when it is in the wall laying state to achieve contact with the wall.

[0023] Furthermore, the flipping mechanism includes a symmetrical track for moving the lead plate fixing component and a lifting hinge frame. The lifting hinge frame includes a fixed roller fixed on the moving platform. Both ends of the fixed roller are hinged with hinge plates. The other end of the hinge plate is hinged to the middle of both sides of the lead plate fixing component. A lead screw is provided in the symmetrical track, and the lead screw is connected to a drive motor through a transmission component. A slider is provided on the lead screw. The slider is hinged to the end of the lead plate fixing component away from the lifting hinge frame. Driven by the drive motor, the slider moves the lead plate fixing component. Due to the restriction of the lifting hinge frame, it will cause the lead plate fixing component to flip and continue to move until the lead plate fixing component is in a wall-mounted state.

[0024] Furthermore, the lead plate fixing component includes a rectangular frame with grooves on its inner wall. Each groove has a sliding plate, which includes a sliding plate and a cross plate. A placement plate is connected to the sliding plate. The upper surface of the placement plate has a lead plate clamping area, and the lower surface has a cavity. Each of the four corners of the placement plate has a rectangular through hole. An automatic screw-in component is provided in each rectangular through hole. The automatic screw-in component is used to screw in the fastener to fix the lead plate to the keel frame.

[0025] Furthermore, the automatic screw-in component includes four sets of sleeves. The sleeves are inserted through rectangular through holes and their rotation is restricted by limiting plates. A sprocket or synchronous pulley is fixedly connected to the periphery of each sleeve. The sprocket or synchronous pulley is equipped with a chain or synchronous belt. One of the sleeves is connected to a motor. The motor drives the sleeve to rotate and synchronously drives the remaining sleeves to rotate. Each sleeve has a polygonal cavity inside. The polygonal cavity is used to insert a fastener with a head.

[0026] The beneficial effects of this invention are:

[0027] 1. This invention is applicable to the installation of lead plates in various radiomedical rooms, especially suitable for radiomedical rooms with lead plate thickness exceeding 3mm, structural net height less than 4.5m, and no space available for constructing light steel brackets above the ceiling. In such cases, using this patented technology for the installation of lead plates on the walls and ceilings of radiation protection projects has advantages such as strict and reliable radiation protection, convenient and efficient installation and construction, reduced economic investment, and standardized and regulated quality control. It can effectively avoid a significant increase in project settlement costs and solve a series of shortcomings of traditional methods.

[0028] 2. As the national and industry standards for radiation protection engineering design further increase the requirements for radiation protection, the thickness of the lead plates used will be thicker, the requirements for the tightness of radiation protection will be higher, and the requirements for the installation of lead plates will be higher and more complex. This patent will surely be more widely promoted and applied.

[0029] 3. With the rapid pace of upgrading medical equipment, the original radiology rooms are gradually being phased out and need to be renovated and expanded. This patent is particularly applicable to the renovation and expansion projects of radiology rooms.

[0030] 4. This invention provides an auxiliary device for installing lead plates. This auxiliary device can switch between two states: ceiling paving and wall paving, enabling multi-directional lead plate installation. Furthermore, this auxiliary device can work in conjunction with manual labor, reducing manual labor and thus reducing labor costs and improving work efficiency.

[0031] 5. Currently, there are no national or industry-wide unified acceptance standards for radiation protection engineering. Therefore, construction units are required to develop their own enterprise standards and organize all participating parties to conduct specialized project quality acceptance according to these standards. This situation will change after the patent for this invention is approved. Based on this patented technology, the second method in a series of lead plate installation construction methods will be developed (note that the method developed based on the "previous patent"—the lead plate installation construction method for radiation protection engineering in radiology rooms—passed the Zhejiang Provincial 2023 Construction Method Review in September 2023). Simultaneously, a quality acceptance standard for radiation protection engineering will be developed, reviewed and approved by experts, and submitted to the relevant government department for approval before being elevated to an industry / national standard, allowing for widespread application throughout the industry.

[0046] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments. In order to confine medical radioactive rays within a specific medical room, lead plates must be installed on the six outer surfaces (walls, ceiling, and floor) of the specific room for radiation shielding protection, forming a safe and reliable medical space for radiation applications. The installation of the lead plates must not only meet the requirements of strict radiation protection and prevent radiation leakage from harming human health, but also meet the various functional requirements of the medical room, and take into account the room's decoration requirements.

[0047] See attached document Figures 1-13 As shown, this application provides a construction process for installing lead plates on the walls and ceilings of radiation protection engineering in a radiology room, according to Embodiment 1. After the main structure of the radiology room is completed, corresponding wall and ceiling base repair work is carried out according to the nature of the wall 1. For example, if the wall 1 is a reinforced concrete structure, the joints of the wall surface are ground and smoothed; if the wall 1 is a solid cement brick wall, a cement mortar plaster layer 2 is formed on the wall surface. The following describes the construction process steps according to the present invention.

[0048] The first step is to repair and verify the wall surface 1, the top surface 10, and the base surface, such as verifying whether the dimensions of the object match the design and construction. Figure 1 To ensure that all pre-reserved and pre-embedded items are in place, etc.

[0049] The second step is on-site layout and proofreading, such as... Figure 6As shown, determine the position of the longitudinal and transverse keel 3 on the top surface 10 of wall 1 and their installation sequence. The specifications, spacing and quantity of the fasteners 12 must meet the design requirements.

[0050] The third step, as Figure 3 As shown, the “top-to-bottom” light steel frame 8 designed for the decorative wall panel 9 requires the pre-installation of the post-embedded parts 14 of the light steel frame foundation, and the installation of the post-embedded parts 14 of the medical equipment gantry / rail 15 foundation. Lead plate protection and “nail head wrapping” treatment must be performed during installation.

[0051] Fourth step, following the layout and positioning from step two, install the keel 3 for wall 1 and ceiling 10 lead plates, as shown. Figure 6 As shown, the wall thickness of the keel and the number of fasteners 12 must meet the design requirements, and the pull-out force of the fasteners 12 must be tested on-site to meet the design requirements.

[0052] Step 5: Detailed treatment of wall surface 1 and ceiling surface 10, including door and window openings, louvers, holes, slots, pipeline locations, post-embedded parts 14 of the light steel frame foundation, and post-embedded parts 14 of the steel support foundation of medical equipment pendant tower / rail 15.

[0053] Step 6: Install lead plates on the walls and ceiling, and simultaneously install supporting works such as cables and pipes on the ceiling. These supporting works include: air conditioning system, fresh air system, medical equipment pendant / rail 15, exhaust fan ventilation duct, cable trays, distribution boxes, fire protection facilities, etc.

[0054] Step 7: For the longitudinal and transverse joints of the lead plates on walls (1) and ceiling (10), an additional layer of lead plate (5) is needed to cover the joints and prevent radiation leakage from the joints. (See attached...) Figure 4 , 5 As shown; the width of the lead plate 5 covering the joint is 80-100mm. During installation, the nail heads should be "wrapped". The fixing strip 6 for the additional lead plate 5 on the wall can be made of flat iron (30mm*3mm). (See attached image.) Figure 4 As shown; the top additional layer strip 7, because it also serves as a welded load-bearing component for the ceiling hanger, must be made of steel square tubing, with specifications of 40mm*40mm*3mm, as attached. Figure 5 As shown.

[0055] Step 8: To prevent radiation leakage, a comprehensive inspection and reinforcement of detailed nodes should be carried out, and protective patches should be applied to any leaks in the lead plate.

[0056] Step 9: Special acceptance inspection of lead plate installation. Currently, since there is no national or industry-wide unified special acceptance standard for radiation protection engineering, construction units are required to develop their own enterprise standards and organize all participating parties to conduct special project quality acceptance inspections in accordance with these standards. (Based on this patented technology, a lead plate installation construction method will be developed, along with a radiation protection engineering quality acceptance standard. After expert review and approval, it will be submitted to the relevant government department for approval and then elevated to an industry or national standard, which can then be promoted and applied throughout the industry.)

[0057] Step 10: Fabrication and installation of the "sky-high and ground-level" steel frame 8, including the steel supports for the medical equipment's pendant towers and rails, and welding of the ceiling hangers 13; the purpose of fabricating and installing the "sky-high and ground-level" steel frame 8 is to prepare for the next step of installing the wall panels 9, as shown in the attached document. Figure 3 As shown; the steel support frame for the medical equipment pendant / rail 15 is fabricated and installed for the next step of medical equipment installation, as shown in the attached document. Figure 2 As shown; the purpose of welding ceiling hanger 13 is for the next step of installing the light steel keel ceiling, as shown in the attached document. Figure 2 , 5 As shown;

[0058] Step 11: Proceed to the next process, wall panel installation and light steel keel ceiling finishing.

[0059] This second embodiment is basically the same as the first embodiment, except that: since the lead plate has a large specific gravity (11.345g / cm3), it is laborious and time-consuming to install the lead plate by manpower alone. The auxiliary equipment 16 designed by this invention can be used to install the lead plate on the keel frame 3 on the top surface of the wall in sequence through fasteners 12. The auxiliary equipment 16 is used for automatically laying lead plates 4. The auxiliary equipment 16 includes a mobile frame 161, a guide rod 162 on the mobile frame 161, and a mobile platform 163 on the guide rod 162. The mobile platform 163 is equipped with a lifting component 164 that drives the mobile platform 163 to move up and down along the guide rod 162. The mobile platform 163 is equipped with a lead plate fixing component 165 that fixes the lead plate 4 to the wall frame 3 and / or the top frame 3. The lead plate fixing component 165 is equipped with a flipping mechanism 166, which is used to flip the lead plate fixing component 165 to achieve switching between the two states of top 10 laying and wall laying. The mobile platform 163 is also equipped with a pushing component 167, which is used to push the lead plate fixing component 165 to move when it is in the wall laying state so that it fits against the wall.

[0060] The flipping mechanism 166 includes a symmetrical track 1661 for moving the lead plate fixing member 165 and a lifting hinge frame. The lifting hinge frame includes a fixed roller 1662 fixed on the moving platform 163. Both ends of the fixed roller 1662 are hinged to hinge plates 1663. The other end of the hinge plate 1663 is hinged to the middle of the two sides of the lead plate fixing member 4. The symmetrical track 1661 is provided with a lead screw 1664, which is connected to a drive motor through a transmission component. The lead screw 1664 is provided with a slider 1665. The slider 1665 is hinged to the end of the lead plate fixing member 165 away from the lifting hinge frame. Driven by the drive motor, the slider 1665 moves the lead plate fixing member 165. Due to the restriction of the lifting hinge frame, the lead plate fixing member 165 will flip and continue to move until the lead plate fixing member 165 is in a wall-mounted state.

[0061] The lead plate fixing component 165 includes a rectangular frame 1651 with grooves on its inner wall. Each groove has a sliding plate 1652. Each sliding plate 1652 includes a sliding plate 1652 and a cross plate 1653. A placement plate 1654 is connected to each sliding plate 1652. The upper end face of the placement plate 1654 has a lead plate clamping area 1655, and the lower end face has a cavity 1657. Each of the four corners of the placement plate 1654 has a rectangular through hole 1656. An automatic screw-in component 17 is provided in each rectangular through hole 1656. The automatic screw-in component 17 is used to screw in the fastener 12 to fix the lead plate 4 to the keel frame 3.

[0062] The automatic screw-in component 17 includes four sets of sleeves 171. Each sleeve 171 is disposed through a rectangular through hole 1656 and is restricted from rotating by a limiting plate. Each sleeve 171 is fixedly connected to a sprocket 173 or a synchronous pulley. The sprocket 173 or synchronous pulley is provided with a chain 174 or a synchronous belt. One of the sleeves 171 is connected to a motor. The motor drives the sleeve 171 to rotate and synchronously drives the remaining sleeves 171 to rotate. Each sleeve 171 is provided with a polygonal cavity 172. The polygonal cavity 172 is used to insert a fastener 12 with a head.

[0063] The above improvements are specifically as follows: (Refer to...) Figures 9-13As shown, the wall lead plate 4 and the ceiling lead plate 4 are automatically installed using auxiliary equipment 16, which can reduce construction costs and improve installation efficiency. Auxiliary equipment 16 includes a mobile frame 161, a guide rod 162 on the mobile frame 161, and a mobile platform 163 on the guide rod 162. The mobile platform 163 is equipped with a lifting component 164 that drives the mobile platform 163 to move up and down along the guide rod 162. The lifting component 164 is hydraulically driven or electrically driven (since the lifting component 164 is existing technology, it will not be described in detail here). (Description) The mobile platform 163 is equipped with lead plate 4 fixing parts for fixing lead plates 4 to the wall keel 3 and / or the top 10 keel. The lead plate 4 fixing parts are equipped with a flipping mechanism 166. The flipping mechanism 166 is used to flip the lead plate 4 fixing parts to realize the switching between the two states of top 10 paving and wall paving, realize multi-directional paving of lead plates 4, reduce manual labor, and the auxiliary equipment 16 works synchronously with the manual labor. The auxiliary equipment 16 paves the lead plates 4, and the manual labor fixes the additional layer 5, which speeds up the construction progress while ensuring the orderliness. The flipping mechanism 166 includes a symmetrical track 1661 for moving the lead plate fixing member 165 and a lifting hinge frame. The lifting hinge frame includes a fixed roller 1662 fixed on the moving platform 163. Both ends of the fixed roller 1662 are hinged to hinge plates 1663. The other end of the hinge plates 1663 is hinged to the middle of the two sides of the lead plate fixing member 4. A lead screw 1664 is provided in the symmetrical track 1661, and the lead screw 1664 is connected to a drive motor through a transmission component. The transmission component includes a driven sprocket 173 at the end of the lead screw 1664. The drive rod of the drive motor is provided with a drive sprocket 173 corresponding to the driven sprocket 173. A chain 1 is provided between the drive sprocket 173 and the driven sprocket 173. 74 or a synchronous pulley is provided, the synchronous pulley is provided with a synchronous belt; a slider 1665 is provided on the lead screw 1664, the slider 1665 is hinged to the end of the lead plate fixing member 165 away from the lifting hinge frame. By rotating the drive motor, the lead screw 1664 rotates, the slider 1665 moves along the direction of the drive motor, the lead plate fixing member 165 is restricted by the hinge plate 1663 and will drive the lead plate fixing member 165 to flip and then continue to move until the lead plate fixing member 165 is in the wall-mounted state. The wall-mounted state is that the lead plate fixing member 165 is vertical and can fit the lead plate 4 to the wall. The top surface 10 is in the wall-mounted state that the lead plate fixing member 165 is horizontal and can fit the lead plate 4 to the top surface 10.The lead plate fixing component 165 includes a rectangular frame 1651 with grooves on its inner wall. Each groove contains a sliding plate 1652. The sliding plates 1652 are provided because when the lead plate fixing component 165 is flipped by the flipping mechanism 166, it retracts inward towards the drive motor, creating a distance between the lead plate 4 and the wall. The sliding plates 1652 then move to fit against the wall. Each sliding plate 1652 includes multiple sliding plates, preferably four, all connected to a cross plate 1653. The cross plate 1653 enables synchronous linkage of the sliding plates 1652 and improves efficiency. The stability between the sliding plates 1652 is ensured by the common connection of the placement plate 1654 on the sliding plates 1652. The upper surface of the placement plate 1654 is provided with a lead plate clamping area 1655. The four corners of the lead plate clamping area 1655 are provided with L-shaped clamping plates. In order to ensure the clamping tightness of the clamping plates, a telescopic component can be provided inside the clamping plate (the telescopic component is existing technology and will not be described in detail here, nor is it shown in the attached figure). During the process of the lead plate 4 adhering to the wall, the telescopic component can hold the lead plate 4 in place. When the lead plate 4 is fixed to the keel frame 3 by the automatic screw-in component 17, the telescopic component retracts and disengages from the lead plate 4 when the auxiliary equipment 16 moves outward. The lower end face of the placement plate 1654 has a cavity 1657. Each of the four corners of the placement plate 1654 has a rectangular through hole 1656. The automatic screw-in component 17 is located within the rectangular through hole 1656 and is restricted by the limiting plate to allow the sleeves 171 to rotate but not move back and forth. The automatic screw-in component 17 includes four sets of sleeves 171. Each sleeve 171 has a polygonal cavity 172, such as a hexagon. A sprocket 173 or a timing pulley is fixedly connected to the periphery of each sleeve 171. The sprocket 173 or timing pulley is equipped with a chain 174 or a timing belt. One sleeve 171 is connected to a motor, which drives the sleeve 171 to rotate and synchronously drives the remaining sleeves. The remaining sleeve 171 rotates, and a motor drives the fasteners 12 at the four corners to rotate synchronously to fix the lead plate 4. The fasteners 12 are screws with hexagonal heads. The screws are placed in the polygonal cavity 172 and rotated to screw them in. Because the screws have hexagonal heads, the screws can be screwed in continuously, thus ensuring that the screws can be safely screwed into the keel frame 3. This auxiliary device 16 can reduce the labor of workers, and only one worker needs to supervise it while the auxiliary device 16 is working, while other workers can work synchronously with the auxiliary device 16, improving work efficiency.

The mobile platform is equipped with a lead plate fixing component that fixes the lead plate to the wall keel frame and / or the ceiling keel frame. The lead plate fixing component is equipped with a flipping mechanism, which is used to flip the lead plate fixing component to realize the switching between the two working conditions of ceiling paving and wall paving. The mobile platform is also equipped with a pushing component, which is used to push the lead plate fixing component to move when it is in the wall paving state to achieve contact with the wall. The flipping mechanism includes a symmetrical track for moving the lead plate fixing component and a lifting hinge frame. The lifting hinge frame includes a fixed roller fixed on the moving platform. Both ends of the fixed roller are hinged to hinge plates. The other end of the hinge plate is hinged to the middle of both sides of the lead plate fixing component. A lead screw is provided in the symmetrical track and the lead screw is connected to a drive motor through a transmission component. A slider is provided on the lead screw. The slider is hinged to the end of the lead plate fixing component away from the lifting hinge frame. Driven by the drive motor, the slider moves the lead plate fixing component. Due to the restriction of the lifting hinge frame, it will cause the lead plate fixing component to flip and continue to move until the lead plate fixing component is in a wall-mounted state. The lead plate fixing component includes a rectangular frame with grooves on its inner wall. Each groove has a sliding plate component, which includes a sliding plate and a cross plate. A placement plate is connected to the sliding plate. The upper surface of the placement plate has a lead plate clamping area, and the lower surface has a cavity. Each of the four corners of the placement plate has a rectangular through hole. An automatic screw-in component is installed in the rectangular through hole. The automatic screw-in component is used to screw in the fastener to fix the lead plate to the keel frame. 7) An additional layer of cover plate is required at the longitudinal and transverse joints of the lead plates on the walls and ceiling; 8) Strengthen the protection of detailed nodes, and take measures such as patching or "wrapping nail heads" to treat any places with nail heads or holes; 9) Special acceptance inspection of lead plate installation; 10) Fabrication and installation of "sky-high and ground-level" light steel frame, fabrication and installation of steel supports for medical equipment hanging towers / rails, and welding of ceiling hangers; 11) Construction of wall paneling and light steel keel ceiling finishing.
