Description

Technical Field

[0001] This invention relates to the field of radiation shielding room technology, specifically to a lightweight, detachable radiation shielding room and its assembly method. Background Technology

[0002] The core principle of radiation shielding rooms is to utilize the absorption and attenuation of radiation by high-density or high-permeability materials, thereby blocking ionizing radiation (such as X-rays and gamma rays) or electromagnetic waves through the shielding body, thus protecting the safety of personnel, equipment and the environment.

[0003] Taking lead plate as an example, due to its high specific gravity, the shielding room is heavy and difficult to transport and install. Traditional lightweight solutions generally have the defect of "reducing weight reduces shielding effectiveness". Therefore, lightweight shielding materials are mainly used for assembly. However, the assembled shielding structure has straight gaps. Conventional modular shielding layers have gaps after assembly. Such gaps are difficult to shield the kinetic energy of rays. Moreover, after repeated disassembly and assembly, they are prone to deformation and overlap failure, resulting in a high risk of leakage. It is impossible to balance disassembly and shielding continuity. In addition, the construction period is long during disassembly and assembly. This invention proposes a solution to this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a lightweight, detachable radiation shielding room and its assembly method to solve the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solution: a lightweight, detachable radiation shielding room, comprising a top plate, corner frames, and multiple single-section panel assemblies, wherein each of the top plate, corner frames, and multiple single-section panel assemblies contains a shielding plate, and the shielding plate includes an outer panel, a lightweight shielding layer, and a lead protective plate;

[0006] The single-section plate assembly is formed by hinged two shielding plates along their length direction, and the single-section plate assemblies are stacked and assembled in the vertical direction to form a combined plate, and each of the combined plates is assembled in a rectangular state.

[0007] The outer edge of the top plate is provided with locking slots for corresponding single-section plate groups and corner frames;

[0008] The corner frame is set at the junction of each combined panel, and the corner frame is provided with a fixing slot for the corresponding single panel group.

[0009] The shielding plate is further configured such that the outer plate and the lead protective plate are located at the outer and inner positions of the combined plate, respectively, and the outer plate and the lead protective plate are fixedly connected, while the lightweight shielding layer is slidably connected in the vertical direction between the outer plate and the lead protective plate.

[0010] A further configuration is provided: a directional pin plate is provided at the position corresponding to the outer plate, and the directional pin plate is used to maintain the horizontal connection of the two shielding plates in the single plate group.

[0011] The lightweight shielding layer is further configured such that its lower and right sides are convex relative to the outer plate and form positioning heads, while its upper and left sides are concave relative to the outer plate and form positioning slots corresponding to the positioning heads.

[0012] Further configuration: multiple top plates are arranged sequentially along their width direction, and horizontally arranged long-handled bolts are provided between the multiple top plates and at the positions corresponding to the single-section plate group of the corner frame; vertically arranged directional screws are provided at the positions of the two shielding plates in the single-section plate group and the top plate corresponding to the single-section plate group.

[0013] The setting is further configured such that the length of the directional screw is greater than that of the lightweight shielding layer, and the upper end of the directional screw is provided with bolt holes corresponding to its lower end portion.

[0014] The present invention also proposes an assembly method for a lightweight, detachable radiation shielding room, including a layout planning stage, a combined panel assembly stage, a corner alignment and reinforcement stage, and a roof sealing and reinforcement stage, specifically as follows:

[0015] Layout planning stage: Determine the length and width of the building according to the on-site construction requirements, and install single-layer single-section panel assemblies along the length and width of the building using directional bolts. The single-section panel assemblies are vertically fixed to the ground of the length and width of the building using directional bolts.

[0016] After completing the layout planning stage, the assembly stage of the combined panels begins: using the vertically fixed single-section panel group as the base, single-layer single-section panel groups are stacked sequentially from bottom to top, and the shielding plates between each adjacent position are interactively fixed by directional screws to form four combined panels;

[0017] After completing the assembly of the composite panels, the corner alignment and reinforcement stage begins: four composite panels are arranged in a rectangle, and corner frames are inserted at the junction of each composite panel using fixing clips. Long-handled bolts for the corresponding single-section panel are installed on the corner frames along the length and width of the corresponding rectangle.

[0018] After completing the above stages, the capping and reinforcement stage begins: the connection with the single-section plate assembly is completed using the fixing clips in the top plate, and finally, it is reinforced with long-shank bolts.

[0019] Finally, a shielded room was obtained.

[0020] The present invention has the following beneficial effects:

[0021] 1. The three-layer composite shielding structure, consisting of an outer panel, a lightweight shielding layer, and a lead shielding plate, significantly reduces the overall weight of the shielding room and solves the problems of difficult transportation and hoisting and poor site adaptability of traditional lead plate shielding rooms. At the same time, the double shielding structure ensures radiation attenuation protection effectiveness and avoids the industry technical contradiction of "reducing weight means reducing shielding effectiveness" in traditional lightweight solutions. Combined with the interlocking structure of the lightweight shielding layer and the full-wrap shielding design of the corner frame, the direct gaps and shielding blind spots at the modular splicing points are eliminated, blocking the radiation leakage channel and greatly improving the safety of radiation protection and the stability of long-term use.

[0022] 2. In addition to the above, the following points are added: The fully modular design of the hinged single-section panels allows for foldable storage of components, significantly reducing space requirements for transportation and storage. All components utilize a snap-fit ​​and bolt-locking assembly method without welding. The accompanying phased assembly method enables rapid construction and complete reverse disassembly of the enclosure, greatly shortening the on-site construction period and reducing the difficulty and labor costs of on-site operations. The accompanying directional screws and long-shank bolt reinforcement structure ensures the overall structural strength of the assembled enclosure, maintaining precise overlap accuracy even after multiple disassemblies and reassemblies, preventing deformation or overlap failure. This allows for the repeated reuse of the shielded enclosure and flexibly adapts to different on-site construction requirements and enclosure construction needs of varying specifications.

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: The radiation shielding room in this example is a rectangular enclosed room structure. A safety door can be opened on one side according to actual requirements. Specifically, it includes four sets of vertically arranged combination panels, four sets of corner frames 1, and multiple top panels 3. The main structure of the combination panels, corner frames 1, and top panels 3 all integrate shielding plates 2, which serve as the core radiation shielding functional components.

[0031] The shielding plate 2 is a three-layer composite plate structure, consisting of an outer plate 201, a lightweight shielding layer 202, and a lead shielding plate 203 from the outside to the inside. The outer plate 201 is made of high-strength alloy plate and provides overall structural support for the room. The lead shielding plate 203 is made of high-purity lead plate and serves as the core radiation shielding body. The lightweight shielding layer 202 is made of lightweight shielding materials such as tungsten alloy fiber and boron-containing polyethylene and is filled between the outer plate 201 and the lead shielding plate 203. Without significantly increasing the weight of the room, it further improves the radiation attenuation efficiency and achieves a lightweight design for the room. The lightweight materials can be varied according to actual requirements.

[0032] The combined panel is assembled by stacking multiple single-section panel groups in the vertical direction. Each single-section panel group is formed by two shielding plates 2 of the same specifications connected by hinges along their length. The single-section panel group can achieve two states: folded storage and unfolded flat. In the folded state, the space occupied for transportation and storage can be greatly reduced. In the unfolded flat state, a complete unit panel can be formed for vertical stacking assembly.

[0033] After the single-section plate assembly is unfolded, a directional pin plate 4 is provided at the joint of the two shielding plates 2. The directional pin plate 4 is fixedly installed on the outer surface of the outer plate 201. It can laterally limit and lock the two shielding plates 2 after unfolding, maintain the horizontal joint state of the two shielding plates 2, avoid the hinge structure from loosening or angular displacement, and ensure the structural stability of the single-section plate assembly. This part is also to facilitate the subsequent directional screw reinforcement process.

[0034] Four sets of combined panels are arranged in a rectangular vertical enclosure to form the main body of the four side walls of the shielded room. At the vertical intersection of two adjacent sets of combined panels, a corner frame 1 is provided. The corner frame 1 is an L-shaped continuous profile structure. The inner side of the frame is provided with a fixing slot that is adapted to the end of the single panel assembly. The end of the single panel assembly can be accurately embedded in the fixing slot to achieve right-angle positioning and snap-fit ​​fixing of adjacent combined panels.

[0035] Multiple top panels 3 are spliced ​​together along the width of the room to form a closed top structure of the shielded room. The outer edge of the top panel 3 is provided with locking slots that correspond to and match the upper end of the single-section panel assembly and the upper end of the corner frame 1. The top panel 3 can be precisely locked and positioned with the side wall structure below through the locking slots.

[0036] Based on the above structural description, the overall structure of the room in this embodiment adopts a modular design. All components are prefabricated in the factory. On-site assembly only requires snap-fit ​​assembly and fastener locking to complete the room construction. There is no need for on-site welding, cutting or other processing operations, which greatly reduces the difficulty of on-site construction. At the same time, it can be disassembled and reversed, and all components can be reused. This solves the technical problems of traditional fixed shielding rooms being unable to be moved and reused and traditional modular shielding rooms being difficult to disassemble and assemble.

[0037] Example 2: This example is an optimized implementation based on the basic scheme of Example 1, focusing on improving the continuity and leakage prevention performance of radiation shielding. It primarily addresses the technical problems of radiation leakage easily occurring at the joints of existing modular shielding rooms and the decrease in shielding effectiveness after repeated disassembly and reassembly. The specific improvements are as follows:

[0038] The outer plate 201 of the shielding plate 2 and the lead shielding plate 203 are fixedly connected by welding or bolt fastening. A vertical sliding groove is formed between the two to adapt to the lightweight shielding layer 202. The lightweight shielding layer 202 is vertically slidably connected to the outer plate 201 and the lead shielding plate 203 through the sliding groove. This structure can complete the pre-installation of the lightweight shielding layer 202 in the factory prefabrication stage, and can also quickly replace the lightweight shielding layer 202 of different materials and thicknesses on site according to the radiation protection level requirements, flexibly adapting to the protection requirements of different working conditions without replacing the entire shielding plate 2.

[0039] The lower end and right edge of the lightweight shielding layer 202 are convex relative to the corresponding edges of the outer plate 201, forming an integrally molded positioning head; the upper end and left edge of the lightweight shielding layer 202 are concave relative to the corresponding edges of the outer plate 201, forming a positioning groove that perfectly matches the size and shape of the positioning head. This part can be referred to... Figure 3 ;

[0040] When the single-section panels are vertically stacked and assembled, the positioning clip at the lower end of the lightweight shielding layer 202 in the upper single-section panel can be precisely embedded into the positioning slot at the upper end of the lightweight shielding layer 202 in the lower single-section panel, forming a vertical staggered overlapping structure. When adjacent shielding panels 2 are horizontally joined, the positioning clip on the right side of the lightweight shielding layer 202 in the left shielding panel 2 can be precisely embedded into the positioning slot on the left side of the lightweight shielding layer 202 in the right shielding panel 2, forming a horizontal staggered overlapping structure. This staggered overlapping structure avoids the straight gaps that exist in traditional modular splicing structures, structurally blocking the channel for radiation leakage through splicing gaps. Even if there are gaps in the lead material protection process, they can be further isolated and protected by the lightweight shielding layer in the middle layer. Conversely, even if there are gaps in the lightweight shielding layer, they can be further isolated and protected by the lead material protection process.

[0041] Simultaneously, the fitting and engagement of the positioning card head and the card slot can achieve rapid pre-positioning during the assembly of adjacent shielding plates 2, which greatly reduces the difficulty of on-site alignment and assembly, and improves assembly efficiency and splicing accuracy.

[0042] In this embodiment, the L-shaped inner cavity of the corner frame 1 also integrates a composite shielding layer with the same structure as the shielding plate 2, which can form a full-wrap shielding coverage for the splicing gap at the junction of adjacent composite plates, eliminating the shielding blind spot at the corner of the room.

[0043] Meanwhile, the corner frame 1 and the single-section panel are locked together by multiple sets of horizontally set long-handled bolts. The long-handled bolts can pass through the corner frame 1 and the single-section panel on both sides along the length and width of the room, so as to achieve overall reinforcement of the corner position and avoid the problem of loosening and gap expansion at the corner position after multiple disassembly and assembly, thus ensuring the shielding stability of the room after long-term use and multiple disassembly and assembly.

[0044] The locking slot of the top plate 3 is also equipped with a sealing and shielding gasket. After the top plate 3 is engaged with the lower single-section plate group and the corner frame 1, the horizontal locking between adjacent top plates 3 is completed by the horizontally set long-handled bolts, and the vertical locking between the top plate 3 and the lower single-section plate group is completed by the vertically set directional screws 5, so as to achieve full-enclosed shielding at the top splicing position, eliminate the risk of radiation leakage from the top gaps, and achieve no dead angle shielding protection for the entire area of ​​the room.

[0045] Example 3: This example, based on the structures of Examples 1 and 2, introduces the complete assembly method of the radiation shielding room in this invention, as well as the supporting structural details for quick assembly and disassembly and multi-specification reuse, as follows:

[0046] The lightweight, detachable radiation shielding room assembly method of this embodiment is divided into four core steps: layout planning stage, combined panel assembly stage, corner alignment and reinforcement stage, and roof reinforcement stage. The entire process does not require on-site welding operations and can be completed with only conventional tools.

[0047] During the layout planning phase, the length, width, and installation location of the shielding room are first determined based on on-site construction requirements and radiation protection needs. An installation baseline is then marked on the ground. Subsequently, the bottom layer of single-section panels is laid along the baseline, and the panels are unfolded to the desired size. Figure 3 In the vertical docking state shown, the two shielding plates 2 are horizontally locked by the directional pin plate 4, and then the bottom single-section plate group is locked and fixed to the ground embedded parts or ground fixed base by the vertically set directional screw 5, so that the bottom single-section plate group maintains a stable vertical fixed state, forming the assembly base of the house body.

[0048] During this stage, the lower end of the directional screw 5 is connected to the ground fixing structure, and the upper end extends upward to provide a vertical positioning reference for the subsequent stacking and assembly of upper single-section plates, ensuring the verticality and accuracy of the subsequent stacking and assembly.

[0049] During the assembly stage of the combined panel, the bottom single-section panel group fixed vertically serves as the assembly base. Single-layer single-section panel groups are stacked sequentially from bottom to top. Each stack of single-section panel groups is fixed by vertically arranged directional screws 5. It should be noted that the lightweight shielding layer 202 in each shielding plate 2 tends to move downward through the directional screws 5, which, together with the outer frame (outer plate 201 and lead protective plate 203), makes each lightweight shielding layer 202 fully "pressed" together.

[0050] In this embodiment, the length of the directional screw 5 is greater than the vertical height of a single shielding plate 2, and it can simultaneously penetrate two adjacent single-section plate groups to achieve overall locking of the interlayer structure; at the same time, the upper end of the directional screw 5 is provided with an internal threaded bolt hole, and the lower end is provided with an external threaded connector that matches the bolt hole, which can realize the end-to-end extension of multiple directional screws 5 to adapt to the assembly needs of room bodies of different heights, without the need to customize fasteners of various specifications, thus improving the versatility of the assembly;

[0051] When assembling adjacent single-section panels, the positioning clips of the upper lightweight shielding layer 202 and the positioning slots of the lower lightweight shielding layer 202 are precisely engaged to form a staggered overlapping shielding structure. While completing the structural fixation, the continuity of interlayer shielding is ensured. Each time a set of combined panels is stacked and assembled, the shielding protection structure of the side wall on that side is built simultaneously, which greatly improves the assembly efficiency.

[0052] During the corner alignment and reinforcement stage, after all four composite panels are stacked and assembled and formed a rectangular vertical enclosure, corner frame 1 is inserted vertically from top to bottom at the vertical intersection of two adjacent composite panels, so that the fixing slots on the inner side of corner frame 1 are fully engaged with the end of the single-section panel at the corresponding position, thus completing the positioning and calibration of the corners of the building and ensuring the squareness of the overall structure of the building.

[0053] After all four sets of corner frames 1 are installed in place, long-handled bolts are inserted horizontally along the length and width of the room to lock the corner frames 1 to the corresponding single-section panels on both sides, thus completing the overall reinforcement of the side wall structure of the room. At the same time, the full-wrap shielding structure of the corner frames 1 completes the shielding and sealing of the corner positions, eliminating the risk of corner leakage.

[0054] During the capping and reinforcement stage, the top plate 3 is first hoisted to the top of the room, so that the locking slots on the outer edge of the top plate 3 are precisely aligned and locked with the upper end of the single-section plate group and the corner frame 1 below. After multiple top plates 3 are spliced ​​together in sequence along the width of the room, the horizontal locking between adjacent top plates 3 is completed by using horizontally set long-handled bolts. Then, the top plate 3 is locked through to the single-section plate group below by using vertically set directional screws 5, completing the closed assembly and reinforcement of the top of the room, and finally forming a fully enclosed radiation shielding room.

[0055] In this embodiment, the disassembly process of the room can be performed in complete reverse. The fasteners of the top plate 3 are removed in sequence, the top plate 3 is removed, the fasteners of the corner frame 1 are removed, the corner frame 1 is removed, and then the individual panel groups are disassembled from top to bottom. After folding and storing, the overall disassembly of the room can be completed. All components are disassembled without destructive disassembly and can be directly transported to the next site for repeated assembly and use. After multiple disassemblies and reassemblies, the precise splicing accuracy and stable shielding performance can still be maintained.
