Description

Technical Field

[0001] The invention relates to a lead plate installation construction method for a radiation protection project in a radiological medical room. Background Art

[0002] The application of radiation technology in the medical field is becoming increasingly widespread, and it has many applications in X-ray diagnostics, clinical nuclear medicine, radiation oncology, etc. The traditional approach is to roughly design the construction drawings of radiation protection projects, and does not solve the specific construction methods of lead plate installation. The two professional designs are not connected with the fine decoration projects. There are problems such as unclear division of construction interfaces, inaccurate calculation of bill of quantities, modifications during construction, and arbitrary construction quality control. As a result, the construction and management of medical rooms are chaotic, or there are problems of radiation leakage during use.

[0003] Upon investigation, a patent application with application number CN202210651492.5, titled "Construction Process for Radiation Protection in Clean Operating Rooms," was discovered. The patent application includes the following steps: S1. Establishing a construction method for a clean ventilation system; S2. Establishing a construction plan for power distribution equipment; S3. Establishing a construction plan for the interior walls of each radiation room; S4. Establishing a construction plan for the interior floors of each radiation room; and S5. Establishing a construction plan for the protective doors of each radiation room. This patent application addresses the construction process for radiation protection in clean operating rooms, but does not address the most crucial aspect of radiation protection engineering: how to install lead sheets. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a lead plate installation and construction method for the radiation protection project of radiological medical rooms. This construction method can ensure that the lead plate fits the medical room without dead angles, provides all-round protection for the radiological medical room, and effectively prevents the leakage of harmful rays that endanger personal safety; at the same time, the present invention takes into account the requirements for the fine decoration construction of radiological medical rooms, and ensures a close connection between the radiation protection project and the fine decoration project.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a method for installing lead plates for radiation protection engineering in radiological medical rooms, which mainly includes the following steps:

[0006] S1. After the main structure of the radiology room is completed and passed the acceptance, the radiation protection project and secondary decoration project will begin;

[0007] S2. Determine the technical plan for the radiation protection project;

[0008] The design unit designs a draft plan for review. After the professional unit reviews and evaluates it, the opinions are fed back to the design unit. The design unit makes adjustments based on the evaluation unit's opinions and determines the final draft of the professional design technical plan. After the construction unit enters the site, further detailed design of the construction drawings is required.

[0009] S3. Carry out radiation protection engineering construction on the ground;

[0010] S4. Carry out radiation protection engineering construction on the wall;

[0011] According to the professional construction drawings after in-depth design, lead sheets are laid on the walls. Auxiliary tools are used to adopt special construction and installation techniques to install the lead sheets on the walls. They are fixed with transverse battens and expansion screws. The screw heads are covered. Two lead sheets are installed by overlapping or splicing. A protective lead sheet reinforcement layer of the same thickness must be added at the splicing point. The protective lead sheet reinforcement layer is 100mm wide and fixed with flat iron battens. Radiation protection reinforcement measures must be taken at local nodes such as holes and troughs in the wall.

[0012] S5. Carry out radiation protection works on the top surface;

[0013] According to the professional construction drawings after in-depth design, a light steel frame is erected on the room ceiling. The base layer of fire-retardant panels is laid on the light steel frame. Radiation protection is first strengthened at the local nodes of the ceiling. Then, lead plates are laid on the base layer of fire-retardant panels. The two lead plates are installed by overlapping.

[0014] S6. Carry out fine decoration construction according to the fine decoration construction drawings;

[0015] For fine wall decoration, first build the vertical keel / grill of the wall panel on the horizontal strip. The vertical keel / grill is fixed with flat head screws. After installation, the flat head screws must not protrude from the surface of the vertical keel / grill. The length of the flat head screws must be shorter than the thickness of the horizontal strip. Then install the wall panel.

[0016] For fine decoration of the ceiling, it is necessary to weld the hangers of the light steel keel of the suspended ceiling on the light steel frame and then install the suspended ceiling;

[0017] The ground is finely decorated and the finishing layer is paved.

[0018] Furthermore, the specific process of laying lead sheets on the ground in S3 is as follows:

[0019] ①. Level the surface of the ground structure slab, round the surrounding inner corners, and clean the wall footing surface within the range of the ground structure lowering slab;

[0020] ②. Lay lead plates on the surface of the ground structure plate and flatten them. The two lead plates should be overlapped with each other, and the overlap width should be greater than 50mm;

[0021] ③. Lay a waterproof protective layer on the surface of the lead plate. The waterproof protective layer can be made of 3mm thick SBS waterproof membrane, which can be pasted in spots;

[0022] ④. Carry out the construction of medical equipment foundation and cable trench according to the construction drawings and the requirements of medical equipment;

[0023] ⑤. Use lightweight aggregate concrete to backfill the ground structure drop-off area, lay a 50mm fine stone concrete base on the lightweight aggregate concrete surface, and use 20mm cement mortar to level the base surface;

[0024] Furthermore, the specific process of the wall radiation protection project in S4 is as follows:

[0025] ①. Check the surface of the wall base and the reserved hole slots, and review the dimensions and pre-buried pipelines;

[0026] ②. Install lead sheets on the wall. Use auxiliary tools and special construction and installation techniques to install the lead sheets on the wall. Install them along the wall in sequence and fix them with horizontal battens and expansion screws. Cover the screw heads until the height of the wall lead sheet exceeds the top lead sheet elevation by 100mm. The horizontal connection between the two lead sheets installed on the wall is overlapped with a width greater than 50mm. The vertical connection between the two lead sheets is spliced. Then, add a protective lead sheet reinforcement layer of the same thickness at the splicing point. The reinforcement layer lead sheet is 100mm wide and fixed with flat iron battens.

[0027] ③. Carry out radiation protection treatment on local node positions of the wall, including door and window openings, holes, troughs and pipelines, and strengthen protection with lead plates;

[0028] ④. Inspect and accept the installation of wall lead plates.

[0029] Furthermore, the specific process of paving the top surface with lead plates in step S5 is as follows:

[0030] ①Inspect the base, check the dimensions, layout and set out, and determine the installation sequence of the suspended ceiling lead plate;

[0031] ②. Make the top light steel frame. The design and installation of the light steel frame must be coordinated with the needs of the subsequent professional supporting projects for construction and installation. The light steel frame is fixed to the wall with high-strength expansion screws.

[0032] ③. Carry out interspersed construction and installation of professional supporting projects, including air conditioning systems, fresh air systems, medical equipment cranes / cranes, exhaust fan ducts, cable and wire bridges, distribution boxes, and fire protection facilities;

[0033] ④. When laying the base fire retardant panels on the light steel frame, if there is any unevenness between the base fire retardant panels and the light steel frame, use gaskets to level them. The gaskets used for leveling must be fixed to the light steel frame with screws to prevent them from falling off. Ensure that the flatness and height difference of the base fire retardant panels after installation are less than 5mm.

[0034] ⑤. Carry out radiation protection treatment on local node positions of the top surface. Local node positions including holes, trough boxes and pipelines are protected by lead plates;

[0035] ⑥. Lay lead sheets on the base fire retardant board, flattening, fixing and enclosing nail heads while paving the lead sheets. At the inner corner where the top lead sheet meets the wall lead sheet, bend the 100mm lead sheet reserved on the wall lead sheet by 90° to ensure that the joints between the top and wall lead sheets are tightly protected.

[0036] ⑦. Inspect and accept the installation of top lead plate.

[0037] Furthermore, the auxiliary tools in step ② include wood boards and wooden paddles, and the specific process is as follows:

[0038] ①. Choose a wood board with a width greater than that of the lead sheet and a length equal to the height of the lead sheet on the wall. Place the wood board flat on the ground, align it with the position of the lead sheet on the wall, place the rolled lead sheet on the wood board with the head facing outwards, unfold the lead sheet, and flatten it with a wooden paddle.

[0039] ② Flatten the lead plate, pull it out 100mm from the end of the wood board and bend it downward to cover the end of the wood board (1);

[0040] ③. Place one end of the wood board against the wall foot, lift the other end together with the lead plate, and stand it against the wall. Slightly adjust the position of the wood board so that the lead plate is aligned with the position on the wall. Hold the wood board with both hands to make it stand steadily against the wall.

[0041] ④. The worker goes to the operating table, flattens the 100mm lead plate bent on the top of the wood board, and temporarily fixes the lead plate to the wall with cement nails;

[0042] ⑤. Remove the wood board, fine-tune the lead plate again, and use horizontal pressure strips and expansion screws to formally fix the lead plate to the wall, and at the same time take measures to cover the nail heads.

[0043] Furthermore, the auxiliary tool in step ② is a laying device, which includes a movable base, two L-shaped rods are provided on the side of the movable base with the notches facing outward, a coil rack is provided between the bottoms of the L-shaped rods, the coil rack is equipped with a driving member, a clamping movable member is provided at the notch, the clamping movable member is used to pull the end of the clamped lead plate upward and lay it on the wall, and then a lifting member is provided through the clamping member, the lifting member moves back and forth with the clamping member, the clamping member flattens the lead plate with the transverse pressure strip and positions the transverse pressure strip, and then fixes the transverse pressure strip with expansion screws.

[0044] Furthermore, the clamping moving part includes a lifting plate driven by a screw rod, a motor is provided in the middle of the lifting plate, and a first synchronous belt and a second synchronous belt are provided on the motor. The first synchronous belt screw is connected to the left grabbing clamp, and the second synchronous belt screw is connected to the right grabbing clamp. The motor drives the first synchronous belt and the second synchronous belt to rotate, driving the screw to rotate, driving the left grabbing clamp and the right grabbing clamp to move up and down, thereby realizing the clamping and disengagement of the left grabbing clamp and the right grabbing clamp.

[0045] Furthermore, the clamping member includes a construction platform, a notch is provided at the bottom of the construction platform, and a transport roller for transporting the transverse pressure strip is provided at the notch. A pushing member is provided at the end of the corresponding transport roller on the construction platform, and the pushing member pushes the transverse pressure strip to stick tightly to the lead plate and the wall. The construction platform is equipped with a lifting member, which drives the construction platform to rise and fall, thereby driving the transverse pressure strip to move.

[0046] Furthermore, when the thickness of the lead plate is greater than 3 mm, the lead plate is split into two layers and installed on the wall in sequence according to the steps, and the horizontal joints of the two layers of lead plates are staggered.

[0047] Furthermore, the nail head is a rectangular lead plate of the same thickness arranged between the transverse pressure strip and the lead plate or between the lead plate and the light steel frame. The screw is driven into the center of one half of the rectangular lead plate, and the other half of the rectangular lead plate is bent. The bent part covers the screw head to ensure that the hole formed by the screw penetrating the lead plate is tightly protected.

[0068] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0069] Example 1

[0070] Reference Figures 1 to 3 、 Figure 8 As shown, a method for installing lead plates for radiation protection engineering in a radiological medical room mainly includes the following steps:

[0071] S1. After the main structure of the radiology room is completed and passed the acceptance, the radiation protection project and secondary decoration project will begin;

[0072] Specifically: when the wall 8 is made of solid cement bricks, it is necessary to paint the wall 8 with cement mortar 2 before performing the radiation protection project; or when the wall 8 is a reinforced concrete structure, it is not necessary to paint it, and the radiation protection project can be performed after the joints of the reinforced concrete wall are polished and smoothed.

[0073] S2. Determine the technical plan for the radiation protection project;

[0074] The design unit designs a draft plan for review. After it is reviewed and evaluated by professional units, the opinions are fed back to the design unit. The design unit makes adjustments based on the opinions of the evaluation unit and confirms the formal draft of the professional design technical plan. After the construction unit enters the site, further in-depth design of the construction drawings is required.

[0075] Specifically, further construction drawing design communication and technical coordination will cover HVAC, intelligent systems, plumbing, fire protection installation, medical gas, medical equipment, and renovation projects. The construction drawing design must meet the requirements of specialized units. Through collaboration among professional assessment units, design units, and specialized construction units, we will address specialized issues in radiation protection engineering and achieve the construction task through the complementary expertise of each unit.

[0076] S3. Carry out radiation protection engineering construction on the ground;

[0077] Specifically, if the floor structure of a radiology room contacts the foundation, radiation protection may not be required to reduce costs. BaSO4 mortar can be used for radiation protection in some radiology rooms. Radiation protection is achieved by paving the floor with lead sheeting 3 in this embodiment. The specific process for paving the lead sheeting 3 includes leveling the floor structure surface using 20mm cement mortar 2 to a flatness of less than 3mm, and rounding the corners of the surrounding wall bases. The floor structure of the room is lowered, and the surface of the wall footing within the structural lowering range is cleaned and leveled, and then protective lead plates 3 are laid. The two lead plates 3 are overlapped, and the overlap width is greater than 50mm. To prevent damage to the lead plates 3 during subsequent construction, a protective layer is laid on the surface of the lead plates 3, and the protective layer uses 3mm SBS waterproof membrane 4. The medical equipment foundation 17 and cable trench 18 are constructed according to the construction drawings and the requirements of the medical equipment. The lightweight aggregate concrete 5 in the structural lowering area is backfilled with ceramsite concrete or foam concrete, and the concrete soil is cured. Then, a layer of fine stone concrete base 6 with strength C20 and thickness of 50mm is made on the surface of the lightweight aggregate concrete 5, and the surface flatness deviation is controlled to be less than 10mm. The surface of the base is then leveled using 20mm thick 1:2.5 cement mortar 2 for leveling, and the flatness is controlled within 5mm. The construction of the floor finishing layer needs to wait until the lead plate protection project of the walls and ceiling is installed. It will be arranged uniformly by the fine decoration construction.

[0078] S4, wall 8 carries out radiation protection engineering construction;

[0079] According to the professional construction drawings after in-depth design, lead plates 3 are laid on the wall 8. Auxiliary tools are used to adopt special construction and installation techniques to install the lead plates 3 on the wall. They are fixed with horizontal pressure strips 10 and expansion screws 24, and the screw heads are covered. The two lead plates 3 are overlapped or spliced for installation. A protective layer of lead plates 3 must be added at the splicing points. Radiation protection is strengthened at local node positions such as holes and trough boxes in the wall 8.

[0080] Specifically: review the dimensions, check the base layer, check the reserved holes and troughs, review the pre-buried pipelines, layout the wall lead plates 3, and determine the installation sequence; perform radiation protection treatment on the local node positions of the wall 8, and the local node positions including door and window openings, holes, troughs and pipelines are protected by lead plates 3; lay the lead plates 3 on the wall, and lay them along the wall in sequence with auxiliary tools, and fix them with horizontal pressure strips 10 and expansion screws 24 until the height of the wall lead plates 3 exceeds the elevation of the top lead plates 3 by 100mm. The installation of the wall lead plate 3 requires the use of an auxiliary wood board (the common specifications of the whole wood board 25 are 1220mm*2400mm*8~12mm). The installation sequence is as follows: a. Select a wood board 25 with a width greater than the width of the lead plate 3 and a length equal to the height of the lead plate 3 on the wall; b. Lay the wood board flat on the ground, align it with the position where the lead plate 3 will be on the wall, place the rolled lead plate 3 on the wood board with the head facing outward, unfold the lead plate 3, and flatten it with a wooden paddle; c. Align the lead plate 3 with the position where it will be on the wall, pull the head of the lead plate 3 out of the head of the wood board by 10cm, bend the lead plate 3 downward to cover the head of the wood board, The purpose is to ensure that the lead plate 3 will not slip in the next step; d. Place one end of the wood board 25 against the wall foot, lift the other end together with the lead plate 3, stand it against the wall, fine-tune the position of the wood board so that the lead plate 3 is aligned with the positioning on the wall, and hold the wood board 25 with both hands to make it stand steadily against the wall; e. The worker goes up to the operating table, flattens the 10cm lead plate 3 bent at the top of the wood board, and temporarily fixes the lead plate 3 to the wall with cement nails; f. Remove the wood board, fine-tune the lead plate 3 again, and then use steel square tube horizontal pressure strips 10 and expansion screws 24 to formally fix the lead plate 3 to the wall 8, and at the same time cover the screw heads. Each horizontal batten 10 is 100mm shorter than the width of each lead sheet 3, with both ends indented 50mm. This allows for a 100mm-wide layer of lead sheet 3 to be added vertically for the joints, or a lap joint is used. The lap width of the lead sheet 3 is at least 50mm. The horizontal battens 10 are spaced 600mm apart, with a deviation of no more than 30mm. These battens are installed sequentially until the wall lead sheet 3 is 100mm higher than the ceiling lead sheet 3. The horizontal battens 10 are made of galvanized steel square tubes. They serve two purposes: first, they hold down the lead sheet 3 and are fixed to the wall 8 with expansion bolts. Second, they serve as the load-bearing member of the decorative wallboard. The vertical keel / grid 11 of the wallboard is fixed to these battens.

[0081] When the thickness of the lead plate 3 is greater than 3mm, it can be installed in two layers. First, temporarily fix the first layer of lead plate 3 on the wall, and then lay the second layer. The horizontal joints of the two layers of lead plates 3 are staggered, with a spacing greater than 500mm. The vertical joints of the two layers of lead plates 3 are aligned and spliced to facilitate installation and construction. A layer of 100mm wide lead plate 3 needs to be added to the vertical joints of the lead plate 3. Flat iron can be used to fix the additional layer of lead plate 3.

[0082] Install protective lead sheeting at detailed joints—including patching holes, covering nail heads, securing door and window openings with lead sheeting, and reinforcing local lead sheeting. The overlap of additional lead sheeting should be no less than 50mm on each side. Patching holes should be done by gluing small squares of lead sheeting of the same thickness with structural adhesive to prevent radiation leakage through the holes.

[0083] A special hidden acceptance inspection for wall radiation protection will be carried out. After the acceptance is qualified, the installation of lead plate 3 on the ground and ceiling will be completed, and then the fine decoration construction will be arranged in a unified manner.

[0084] S5. Carry out radiation protection works on the top surface;

[0085] According to the professional construction drawings after in-depth design, a light steel frame 15 is erected on the ceiling of the room, and a base layer of fire-retardant panels 14 is laid on the light steel frame 15. The local node positions of the ceiling are first subjected to radiation protection reinforcement treatment, and then lead plates 3 are laid on the fire-retardant panels. The two lead plates 3 are installed by overlapping.

[0086] Specifically: check the base, check the dimensions, layout and set out, and determine the installation sequence of 16 lead plates and 3 for the suspended ceiling;

[0087] According to the requirements of construction load, HVAC, intelligent technology, water, electricity and fire protection installation, medical gas, medical equipment and subsequent decoration projects, the light steel frame 15 of the suspended ceiling 16 is further designed and manufactured. The suspended ceiling 16 steel frame is installed on the wall 8 through high-strength expansion screws 24. For easy installation, the light steel frame 15 should be designed and manufactured in sections.

[0088] Carry out interspersed construction and installation of professional supporting projects, including air conditioning systems, fresh air systems, medical equipment cranes / cranes 19, exhaust fan ventilation ducts, cable and wire bridges, distribution boxes, fire protection facilities, etc.;

[0089] Lay the base fire retardant board 14 on the light steel frame 15. If there is any unevenness between the base fire retardant board 14 and the light steel frame 15, use gaskets to level them. The gaskets should be fixed to the light steel frame 15 with screws to prevent them from falling off. It is necessary to ensure that the flatness and height difference of the base fire retardant board 14 after installation are less than 5mm.

[0090] Perform radiation protection treatment on local nodes of the top surface. Local nodes include holes, troughs, and pipelines, and require the use of lead plates 3 for enhanced protection.

[0091] Lay the lead sheet 3 on the base fire retardant board 14, flatten and fix the lead sheet 3 while laying it, and wrap the nail head. When the top lead sheet 3 meets the wall lead sheet 8, bend the 100mm lead sheet 3 reserved by the wall lead sheet 3 by 90° to ensure that the joint between the top and wall lead sheets 3 is tightly protected.

[0092] A special hidden acceptance inspection for the radiation protection of the ceiling will be carried out. After the acceptance is qualified, the installation of the lead plate 3 on the wall and floor will be completed, and then the fine decoration construction will be arranged in a unified manner.

[0093] S6. Carry out fine decoration according to the fine decoration construction drawings;

[0094] The wall 8 is finely decorated, and the vertical keel / grid 11 is built on the horizontal pressure strip 10. The vertical keel / grid 11 is fixed with flat head screws. Note that the screw length must not touch the lead plate 3. Finally, the wall panel is installed;

[0095] The top surface is finely decorated, the hangers of the light steel keel of the suspended ceiling 16 are welded on the light steel frame 15, and then the suspended ceiling 16 is installed;

[0096] The ground is finely decorated and the finishing layer is paved.

[0097] Specifically: Before fine decoration, it is necessary to check the sealing of the lead plate 3. The sealing of the lead plate 3 installation is the key point of the radiation protection project, especially for the node positions of holes, trough boxes, pipelines through the wall, door\window edges, etc. The radiation protection quality of the nodes must be fully inspected and passed; for fine decoration of the wall, the horizontal pressure strip 10 is used as the load-bearing component of the decorative wall panel. The decorative wall panel includes a cement pressure plate base layer 12 and an inorganic coating plate decorative layer 13. The vertical keel\grid 11 of the wall panel is fixed on the horizontal pressure strip 10 and is passed through Fix with flat head screws, use galvanized steel square tube for horizontal pressure strip 10, and adjust and control the verticality and flatness of vertical keel\grill 11 by gasket and angle code to ensure the flatness and verticality of vertical keel\grill 11 before installing wall panels; finish the top surface, weld the suspended ceiling 16 light steel keel on the light steel frame 15, pay attention to air vents, sprinklers, hanging tower\hanging rails, cables, lighting, and then install the suspended ceiling 16; finish the floor, lay decorative panels on the floor, and the decorative panels are PVC floor boards 7.
