Description

Technical Field

[0001] This invention relates to the field of radiation protection engineering construction technology, specifically providing a radiation protection lead plate based on a prefabricated frame structure and its installation method. Background Technology

[0002] Lead plates are commonly used radiation shielding materials in places requiring radiation shielding, such as medical radiology diagnostic rooms and industrial flaw detection rooms. Depending on the installation location, existing lead plate installation processes are mainly divided into the following three categories:

[0003] (1) Surrounding earthen walls: For the surrounding earthen walls of radiation-proof buildings, the traditional installation process of radiation-proof lead plates is to directly use steel nails with small lead pads to nail through the lead plate and connect the lead plate to the earthen wall. Then, the small lead pads are bent to wrap the exposed nail heads.

[0004] (2) Top ceiling: For the top floor of the radiation protection building, first fix the lead plate to the civil engineering ceiling with steel nails, then add angle steel strips on the outer surface of the lead plate to reinforce the lead plate and prevent it from falling off, and then wrap the exposed angle steel strips with lead plate.

[0005] (3) Space partition: If a partition needs to be added in the middle of the space, it is necessary to first build a horizontal and vertical steel frame, install a lining plate on the steel frame to assist the lead plate (wooden board, etc.) to be installed on the wall, and then fix the lead plate on the lining plate.

[0006] The aforementioned traditional processes have the following drawbacks in practical applications:

[0007] (1) There is a risk of radiation leakage when steel nails penetrate lead plates, and the operation is complicated. When fixing lead plates to the surrounding civil engineering walls using existing technology, steel nails need to penetrate the lead plates, which poses a risk of radiation leakage. Each steel nail requires manual folding of lead washers to cover the nail head. After folding, it needs to be hammered to make the joint tight. If the worker does not control the force properly, the lead plate may be damaged, making it difficult to guarantee the quality of the finished lead plate. The operation is complicated and unsightly. It is difficult to carry out these complicated operations at heights, and there is a risk of falling from heights. After the initial lead plate construction is completed, in order to install the interior panel on the inside, a steel frame needs to be welded. During the welding and installation of the steel frame and interior panel, the already completed lead plate surface may be damaged.

[0008] (2) When using existing technology to fix lead plates to the ceiling, since there is no independent steel frame similar to the surrounding civil engineering partition walls on the ceiling, it is difficult to fix the lead plates securely. Fixing the lead plates only by connecting them to the ceiling with screws may cause the lead plates to deform under gravity. Therefore, after fixing the lead plates to the ceiling structure board with screws, steel pressure strips (angle steel or U-shaped through-core keel) need to be added to the inside of the lead plates. The construction steps of this steel frame are relatively complicated, and the exposed inner angle steel pressure strip will weaken the radiation protection effect. It needs to be wrapped, which increases the amount of lead plate material required and the material cost. Ultimately, this results in a lot of complicated construction procedures and high costs for the radiation protection of the ceiling structure board.

[0009] (3) When using existing technology to build radiation shielding walls in space, it is necessary to first erect a longitudinal and transverse steel frame. This step requires a lot of manpower and at least two workers to complete it. Welding is also required. Moreover, the construction quality of the steel frame that the workers manually build to support the weight of the lead plate is affected by the workers' skill level, and the construction quality is difficult to guarantee.

[0010] Therefore, there is an urgent need for a non-perforated, all-scenario applicable radiation shielding lead plate installation structure and its construction method to solve problems such as radiation leakage hazards caused by steel nails penetrating lead plates, construction safety risks caused by manual folding of lead pads and high-altitude operations, material waste caused by insecure fixing of ceiling lead plates and pressure strip wrapping, and complicated construction procedures and uncontrollable quality of partition wall steel frame erection. Summary of the Invention

[0011] The purpose of this invention is to provide a radiation shielding lead plate based on a prefabricated frame structure and its installation method, which solves the construction problems caused by traditional lead plates due to perforation fixation, such as radiation leakage, inability to conceal pipelines, difficulty in misaligning joints, and low efficiency of high-altitude installation.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] A radiation-shielding lead plate based on a prefabricated frame structure includes lead plate units, a prefabricated frame, and steel inserts;

[0014] The lead plate unit includes multiple single-sided No. 1 lead plates and multiple single-sided No. 2 lead plates;

[0015] Both the single-sided No. 1 lead plate and the single-sided No. 2 lead plate are rectangular plates, each including two pairs of parallel sides;

[0016] One pair of sides of the single-sided No. 1 lead plate and the single-sided No. 2 lead plate are provided with wing plates, and the other pair of sides are defined as the No. 1 lead plate side and the No. 2 lead plate side respectively; the axial length of the wing plate of the single-sided No. 2 lead plate is shorter than the side length of the corresponding side of the wing plate, causing the pair of sides to form a missing corner.

[0017] The wing plate of the single-sided No. 1 lead plate and the wing plate of the single-sided No. 2 lead plate are joined together to form an overlapping wing plate combination.

[0018] Multiple sets of lead plate units are arranged alternately and staggered. When adjacent single-sided lead plate No. 1 and single-sided lead plate No. 2 are spliced ​​together, the side of lead plate No. 1 of single-sided lead plate No. 1 is embedded into the notch of single-sided lead plate No. 2, and is supported and limited by the side of lead plate No. 2.

[0019] The prefabricated frame includes two rows of vertical steel frames and two rows of horizontal steel frames, which are connected by screws. L-shaped grooves are provided on the square steel on the outer side of both the vertical and horizontal steel frames, and the gap between the L-shaped grooves is greater than the thickness of the wing plate assembly.

[0020] The steel insert is embedded in the L-shaped groove, and the wing plate assembly is fixed without perforation by tightening the screws.

[0021] Preferably, the vertical steel frame includes a double-row vertical corner steel frame located at the corner and a plurality of double-row vertical steel frames laid out in the left-right direction along the double-row vertical corner steel frame;

[0022] The transverse steel frame includes a transverse corner steel frame located at the left corner and multiple transverse steel frames arranged parallel to the transverse corner steel frame;

[0023] The horizontal corner steel frame and multiple horizontal steel frames are detachably connected to the top of the double-row vertical corner steel frame and the double-row vertical steel frame by screws or bolts.

[0024] Preferably, the double-row vertical corner steel frame, the double-row vertical steel frame, the horizontal corner steel frame and the horizontal steel frame are all constructed by double rows of parallel spaced square steel, which are used to reserve installation space between the double rows of square steel for laying pipelines or air ducts;

[0025] On the outer square steel of the double-row square steel facing the computer room, there are L-shaped grooves extending along the length direction. The gap of the L-shaped grooves is greater than the thickness of the wing plate assembly.

[0026] Preferably, the wing plate of the single-sided No. 1 lead plate includes a No. 1 Z-shaped wing plate and a No. 1 U-shaped wing plate;

[0027] The wing plates of the single-sided No. 2 lead plate specifically include the No. 2 Z-shaped wing plate and the No. 2 U-shaped wing plate;

[0028] The first Z-shaped wing plate of the single-sided lead plate No. 1 covers the second U-shaped wing plate of the single-sided lead plate No. 2, so that the two form a tightly interlocked wing plate combination.

[0029] The outer side of the first U-shaped wing plate of the single-sided lead plate No. 1 is attached to the inner side of the second Z-shaped wing plate of the single-sided lead plate No. 2, so that the two form a tightly interlocked wing plate combination.

[0030] Preferably, it also includes three No. 2 lead plates, two No. 1 lead plates, and two No. 2 lead plates adapted for wall corners and top surfaces;

[0031] The sides of the three-sided No. 2 lead plate and the two-sided No. 2 lead plate are provided with folded edge wing plates that are the same as those of the single-sided No. 2 lead plate, and the sides of the two-sided No. 1 lead plate are provided with folded edge wing plates that are the same as those of the single-sided No. 1 lead plate.

[0032] Furthermore, the ends of the three-sided No. 2 lead plate, the two-sided No. 1 lead plate, and the two-sided No. 2 lead plate are appropriately matched and connected to the missing corner positions of the adjacent single-sided No. 1 lead plate and single-sided No. 2 lead plate, and are staggered with the adjacent lead plate units. The wing plate is formed by superimposing the wing plates of the single-sided No. 1 lead plate and single-sided No. 2 lead plate with the folded edge wing plate, and is installed in the L-shaped groove. The steel insert is embedded and the screw is tightened to achieve non-perforation fixation, ensuring the continuity and sealing of the lead plate installation.

[0033] Preferably, the opening width of the L-shaped groove is smaller than the width of its internal cavity, forming a retaining structure that is larger inside and smaller outside;

[0034] The cross-sectional shape of the steel insert is adapted to the internal cavity shape of the L-shaped groove, and the hardness of the steel insert is greater than the hardness of the lead material of the wing plate assembly.

[0035] Preferably, the distance between the vertical parallel seams of two adjacent sets of lead plate units is greater than 30mm.

[0036] Preferably, the screw head is flush with the surface of the steel insert, and the steel insert is made of stainless steel, forming a continuous radiation-proof sealing surface by the tight pressing of the steel insert and the wing plate.

[0037] In addition, the present invention also provides an installation method for radiation-shielding lead plates based on a prefabricated frame structure, comprising the following steps:

[0038] Step S1, Framework Setup:

[0039] The double-row vertical corner steel frame, double-row vertical steel frame, horizontal corner steel frame and horizontal steel frame are fixedly connected with screws to form an installation space between the double-row square steel for laying pipelines or air ducts, and ensure that the L-shaped groove on the outer square steel of each steel frame faces outward to facilitate the installation of lead plates.

[0040] Step S2, Single lead plate in place:

[0041] Single-sided lead plate No. 1 and single-sided lead plate No. 2 are moved to the installation position in sequence. During installation, the U-shaped wing plate of the lead plate is hung into the L-shaped groove from bottom to top. The lead plate is used to hang it stably on the frame by its own weight. It can be moved horizontally along the groove to adjust the position.

[0042] Step S3, Piece-by-piece splicing and interlocking:

[0043] First, perform horizontal splicing. Splice the single-sided lead plate No. 1 and the single-sided lead plate No. 2 horizontally in sequence, so that the No. 1 Z-shaped wing plate of the single-sided lead plate No. 1 covers the No. 2 U-shaped wing plate of the single-sided lead plate No. 2. At the same time, make the outer side of the No. 1 U-shaped wing plate of the single-sided lead plate No. 1 abut against the inner side of the No. 2 Z-shaped wing plate of the single-sided lead plate No. 2, forming a tightly interlocked wing plate combination, and confirm the missing corner position of the single-sided lead plate No. 2.

[0044] Next, vertically assemble the lead plate wing panels, aligning them with the frame in a direction parallel to the opening of the L-shaped groove. Then, hang the wing panel assembly into the L-shaped groove from bottom to top, using the weight of the lead plate itself to suspend it stably.

[0045] During the hanging process, the relative height of adjacent lead plate units is adjusted so that the side of the No. 2 lead plate of the lower single-sided No. 2 lead plate is embedded below the side of the No. 1 lead plate of the upper adjacent single-sided No. 1 lead plate unit, until the side of the No. 1 lead plate is completely supported and confined above the side of the No. 2 lead plate, forming a stable stepped support structure.

[0046] Both horizontal and vertical splicing adopt a non-perforated interlocking structure, which eliminates the need for welding or secondary fixing;

[0047] Step S4, staggered arrangement:

[0048] Multiple sets of lead plate units are installed sequentially along the vertical and horizontal axes, ensuring that the spacing between the vertical parallel joints of two adjacent sets of lead plate units is greater than mm, in order to meet the requirements for staggered joints in radiation protection.

[0049] Step S5: Tighten and fix:

[0050] The steel insert is embedded in the opening of the L-shaped groove, and the internal wing plate assembly is tightened by screws through the steel insert to achieve hole-free fixing. The steel insert is tightened by screws to ensure that the outer surface is flat and there is no radiation leakage channel.

[0051] Compared with the prior art, the present invention has the following beneficial effects:

[0052] 1. This invention uses a prefabricated frame constructed by connecting steel frames with screws arranged in two parallel rows. It utilizes L-shaped grooves on the outer square steel as guide rails and combines them with steel inserts to install and tighten the wing plates. This technical solution achieves the complete elimination of drilling for lead plates and separate installation of pipeline space. It solves the technical problems of nail hole radiation leakage, pipeline and lead plate installation conflicts, and low efficiency of high-altitude operations caused by drilling and fixing with traditional single-layer keel.

[0053] 2. The present invention forms a main interlock by covering the U-shaped wing plate of the single-sided No. 2 plate with the Z-shaped wing plate of the single-sided No. 1 plate, while using the corner structure reserved in the single-sided No. 2 plate to support and limit the side of the single-sided No. 1 plate, forming a stepped overlapping technical solution; it solves the technical problems of easy misalignment of traditional splicing seams, which leads to the failure of direct radiation protection, and the failure of protection after the lead plate settles due to its own weight.

[0054] 3. The present invention solves the technical problem that the traditional process requires additional partition walls to conceal ventilation ducts, power lines and medical gas pipelines, resulting in more procedures, larger space occupation, higher construction costs, and easy damage to the integrity of lead plate shielding during the installation of decorative surface layer by reserving installation space between the double-row vertical steel frame and the double-row horizontal steel frame.

[0055] 4. This invention uses a modular construction method that connects lead plate units piece by piece from bottom to top, and utilizes the cooperation between the L-shaped groove and the lead plate wing plate to achieve horizontal sliding and interlocking splicing. It solves the technical problems of high difficulty in lifting the soft and heavy lead plate at high altitudes, uneven drilling force that easily cracks the plate, and high material loss.

[0070] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0071] like Figure 2 As shown, this embodiment provides a radiation shielding lead plate based on a prefabricated frame structure, including lead plate units, a prefabricated frame, and steel inserts 10.

[0072] The lead plate unit includes multiple single-sided No. 1 lead plates 8 and multiple single-sided No. 2 lead plates 9;

[0073] Both single-sided No. 1 lead plate 8 and single-sided No. 2 lead plate 9 are rectangular plates, each consisting of two pairs of parallel sides;

[0074] Both the left and right sides of the single-sided lead plate 8 and the single-sided lead plate 9 are provided with wing plates (i.e., protruding or recessed overlapping edges, and the wing plates can be formed step by step by the lead plate bending device on site). The other pair of sides are defined as the lead plate side 8-3 and the lead plate side 9-3 respectively. The axial length of the wing plate of the single-sided lead plate 9 is shorter than the side length of the corresponding side of the wing plate, which causes the pair of sides to form a notch, which is used to embed and support the adjacent lead plates. In this embodiment, the single-sided lead plate 8 in the adjacent lead plate unit is used for embedding support and positioning.

[0075] The wing plate of single-sided lead plate No. 1 8 and the wing plate of single-sided lead plate No. 2 9 are joined together to form an overlapping wing plate combination.

[0076] Multiple sets of lead plate units are arranged alternately and staggered. When adjacent single-sided lead plate 8 and single-sided lead plate 9 are spliced ​​together, the lead plate side 8-3 of single-sided lead plate 8 is embedded into the missing corner of single-sided lead plate 9 and is supported and limited by the lead plate side 9-3.

[0077] like Figure 3 and Figure 4 As shown, in this embodiment, the wing plates of the single-sided lead plate 8 include a Z-shaped wing plate 8-1 and a U-shaped wing plate 8-2.

[0078] The wing plates of the single-sided No. 2 lead plate 9 specifically include the No. 2 Z-shaped wing plate 9-1 and the No. 2 U-shaped wing plate 9-2;

[0079] The first Z-shaped wing plate 8-1 of the single-sided lead plate 8 covers the second U-shaped wing plate 9-2 of the single-sided lead plate 9, so that the two form a tightly interlocked wing plate combination.

[0080] The outer side of the No. 1 U-shaped wing plate 8-2 of the single-sided No. 1 lead plate 8 abuts against the inner side of the No. 2 Z-shaped wing plate 9-1 of the single-sided No. 2 lead plate 9, forming a tightly interlocked wing plate assembly. For details on the wing plate interlocking and stepped support structure, please refer to... Figures 5 to 8 As shown.

[0081] Furthermore, in this embodiment, the spacing between the vertical parallel seams of two adjacent sets of lead plate units is greater than 30mm to avoid direct radiation transmission caused by seam alignment.

[0082] like Figure 1 As shown, the prefabricated frame includes two rows of vertical steel frames and two rows of horizontal steel frames. The vertical steel frames and horizontal steel frames are connected by screws. L-shaped grooves are opened on the square steel on the outer side of both the vertical steel frames and the horizontal steel frames. The gap between the L-shaped grooves is greater than the thickness of the wing plate assembly.

[0083] Furthermore, in this embodiment, the vertical steel frame includes a double-row vertical corner steel frame 1 located at the corner and a plurality of double-row vertical steel frames 2 laid out in the left and right directions along the double-row vertical corner steel frame 1;

[0084] The transverse steel frame includes a transverse corner steel frame 4 located at the left corner and multiple transverse steel frames 3 arranged parallel to the transverse corner steel frame 4;

[0085] The horizontal corner steel frame 4 and multiple horizontal steel frames 3 are detachably connected to the top of the double-row vertical corner steel frame 1 and the double-row vertical steel frame 2 by screws.

[0086] In this embodiment, the double-row vertical corner steel frame 1, the double-row vertical steel frame 2, the horizontal corner steel frame 4 and the horizontal steel frame 3 are all constructed by double rows of parallel spaced square steel, which are used to reserve installation space between the double rows of square steel for laying pipelines or air ducts.

[0087] like Figure 5 and Figure 6 As shown, each of the outer square steel sections facing the machine room in the double-row square steel section has an L-shaped groove extending along its length. The gap between the L-shaped grooves is larger than the thickness of the wing plate assembly, used for inserting the lead plate folded wing plate. (The vertical square steel section facing the interior and away from the lead plate in the double-row square steel pipe can be used for direct installation of interior trim panels later, without the need for additional steel frame welding.)

[0088] Furthermore, in this embodiment, the opening width of the L-shaped groove is smaller than the width of its internal cavity, forming a retaining structure that is larger inside and smaller outside;

[0089] A steel insert 10 is embedded in an L-shaped groove and secured to the wing plate assembly by screws 11, achieving a non-perforated fixing of the wing plate assembly. The cross-sectional shape of the steel insert 10 matches the internal cavity shape of the L-shaped groove, and the hardness of the steel insert 10 is greater than the hardness of the lead material of the wing plate assembly. The screw head of the screw 11 is flush with the surface of the steel insert 10, and the steel insert is made of lead or stainless steel. The tight compression between the steel insert 10 and the wing plate forms a continuous radiation-proof sealing surface.

[0090] Furthermore, such as Figures 9 to 11 As shown, this embodiment also includes a three-sided No. 2 lead plate 5, a two-sided No. 1 lead plate 6, and a two-sided No. 2 lead plate 7 adapted for wall corners and top surfaces.

[0091] The sides of the three-sided No. 2 lead plate 5 and the two-sided No. 2 lead plate 7 are provided with the same folded edge wing plate as the single-sided No. 2 lead plate 9, and the sides of the two-sided No. 1 lead plate 6 are provided with the same folded edge wing plate as the single-sided No. 1 lead plate 8.

[0092] Furthermore, the ends of the three-sided No. 2 lead plate 5, the two-sided No. 1 lead plate 6, and the two-sided No. 2 lead plate 7 are matched and connected to the missing corner positions of the adjacent single-sided No. 1 lead plate 8 and single-sided No. 2 lead plate 9, and are staggered with the adjacent lead plate units. They are combined with the wing plates of the single-sided No. 1 lead plate 8 and single-sided No. 2 lead plate 9 by folding the wing plates to form a wing plate assembly, which is installed in the L-shaped groove. The steel insert 10 is used for embedding and the screw 11 is used for tightening to achieve non-perforation fixation, ensuring the continuity and sealing of the lead plate installation.

[0093] In addition, such as Figure 12 As shown in the figure, this embodiment also provides an installation method for a radiation-shielding lead plate based on a prefabricated frame structure, including the following steps:

[0094] Step S1, Framework Setup:

[0095] The double-row vertical corner steel frame 1, double-row vertical steel frame 2, horizontal corner steel frame 4 and horizontal steel frame 3 are fixedly connected with screws to form an installation space between the double rows of square steel for laying pipelines or air ducts, and to ensure that the L-shaped grooves on the outer square steel of each steel frame face outwards, so as to facilitate the installation of lead plates.

[0096] Step S2, Single lead plate in place:

[0097] Single-sided lead plate No. 1 8 and single-sided lead plate No. 2 9 are moved to the installation position in sequence; during installation, the U-shaped wing plate of the lead plate is hung into the L-shaped groove from bottom to top, and the lead plate is used to hang it stably on the frame by its own weight, and can be moved horizontally along the groove to adjust the position.

[0098] Step S3, Piece-by-piece splicing and interlocking:

[0099] First, perform horizontal splicing. Splice the single-sided lead plate 8 and the single-sided lead plate 9 horizontally in sequence, so that the first Z-shaped wing plate 8-1 of the single-sided lead plate 8 covers the second U-shaped wing plate 9-2 of the single-sided lead plate 9. At the same time, make the outer side of the first U-shaped wing plate 8-2 of the single-sided lead plate 8 abut against the inner side of the second Z-shaped wing plate 9-1 of the single-sided lead plate 9, forming a tightly interlocking wing plate combination, and confirm the missing corner position of the single-sided lead plate 9.

[0100] Next, vertically assemble the lead plate wing panels, aligning them with the frame in a direction parallel to the opening of the L-shaped groove. Then, hang the wing panel assembly into the L-shaped groove from bottom to top, using the weight of the lead plate itself to suspend it stably.

[0101] During the hanging process, the relative height of adjacent lead plate units is adjusted so that the second lead plate side 9-3 of the lower single-sided second lead plate 9 is embedded below the first lead plate side 8-3 of the upper adjacent single-sided first lead plate 8, until the first lead plate side 8-3 is completely supported and confined above the second lead plate side 9-3, forming a stable stepped support structure.

[0102] Both horizontal and vertical splicing adopt a non-perforated interlocking structure, which eliminates the need for welding or secondary fixing;

[0103] Step S4, staggered arrangement:

[0104] Multiple sets of lead plate units are installed sequentially along the vertical and horizontal axes, ensuring that the spacing between the vertical parallel joints of two adjacent sets of lead plate units is greater than 30mm to meet the requirements for staggered joints in radiation protection.

[0105] Step S5: Tighten and fix:

[0106] The steel insert 10 is embedded in the opening of the L-shaped groove, and the screw 11 is passed through the steel insert 10 and tightened against the internal wing plate assembly to achieve a hole-free fixation. The screw head of the screw 11 is tightened against the surface of the steel insert 10 to ensure that the outer surface is flat and there is no radiation leakage channel.

9. A method for installing a radiation-shielding lead plate based on a prefabricated frame structure as described in any one of claims 1-8, characterized in that, Includes the following steps: Step S1, Framework Setup: The double-row vertical corner steel frame (1), double-row vertical steel frame (2), horizontal corner steel frame (4) and horizontal steel frame (3) are fixedly connected with screws to form an installation space for laying pipelines or air ducts between the double-row square steels, and ensure that the L-shaped grooves on the outer square steels of each steel frame face outwards, so as to facilitate the installation of lead plates. Step S2, Single lead plate in place: The single-sided lead plate No. 1 (8) and the single-sided lead plate No. 2 (9) are moved to the installation position in sequence. During installation, the U-shaped wing plate of the lead plate is hung into the L-shaped groove from bottom to top. The lead plate is used to hang it stably on the frame by its own weight, and it can be moved horizontally along the groove to adjust the position. Step S3, Piece-by-piece splicing and interlocking: First, perform horizontal splicing. Splice the single-sided lead plate No. 1 (8) and the single-sided lead plate No. 2 (9) horizontally in sequence, so that the first Z-shaped wing plate (8-1) of the single-sided lead plate No. 1 (8) covers the second U-shaped wing plate (9-2) of the single-sided lead plate No. 2 (9). At the same time, make the outer side of the first U-shaped wing plate (8-2) of the single-sided lead plate No. 1 (8) abut against the inner side of the second Z-shaped wing plate (9-1) of the single-sided lead plate No. 2 (9), forming a tightly interlocked wing plate combination, and confirm the missing corner position of the single-sided lead plate No. 2 (9). Next, vertically assemble the lead plate wing panels, aligning them with the frame in a direction parallel to the opening of the L-shaped groove. Then, hang the wing panel assembly into the L-shaped groove from bottom to top, using the weight of the lead plate itself to suspend it stably. During the hanging process, the relative height of adjacent lead plate units is adjusted so that the second lead plate side (9-3) of the lower single-sided second lead plate (9) is embedded below the first lead plate side (8-3) of the upper adjacent single-sided first lead plate (8) until the first lead plate side (8-3) is completely supported and confined above the second lead plate side (9-3), forming a stable stepped support structure. Both horizontal and vertical splicing adopt a non-perforated interlocking structure, which eliminates the need for welding or secondary fixing; Step S4, staggered arrangement: Multiple sets of lead plate units are installed sequentially along the vertical and horizontal axes, ensuring that the spacing between the vertical parallel joints of two adjacent sets of lead plate units is greater than 30mm to meet the requirements for staggered joints in radiation protection. Step S5: Tighten and fix: The steel insert (10) is embedded in the opening of the L-shaped groove. The screw (11) is passed through the steel insert (10) and tightened to the inner wing plate assembly to achieve hole-free fixing. The screw (11) is tightened to the steel insert (10) to ensure that the outer surface is flat and there is no radiation leakage channel.
