Description

Technical Field

[0001] The present invention relates to the technical field of radiation-proof buildings, in particular to a modular radiation-proof wall structure. Background Art

[0002] Scientific research shows that exposure to ionizing radiation can cause symptoms such as general fatigue, decreased appetite and immunity, chromosome breakage, gene mutation, and infertility, and can even lead to various diseases and serious health hazards. Therefore, in areas exposed to ionizing radiation, particularly hospitals and medical examination centers, radiation shielding walls are often installed outside the rooms where the radiation is generated to effectively isolate the radiation.

[0003] The patent document with application publication number CN117905198A discloses a radiation-proof cavity wall, a radiation-proof prefabricated building, and a construction method. The radiation-proof cavity wall includes: a modular radiation-proof cavity wall having a plurality of cavities arranged side by side in a vertical direction; a plurality of shear keys are pre-embedded inside the modular radiation-proof cavity wall, and a portion of the shear keys is located outside the modular radiation-proof cavity wall; the thickness of the modular radiation-proof cavity wall is greater than a first preset thickness; a steel cage is vertically arranged in the cavity and fixedly connected to the shear keys; concrete is cast in the cavity to form a cast-in-place wall. In the radiation-proof cavity wall of the present invention, the modular radiation-proof cavity wall is both the main load-bearing part and can serve as a formwork for the cast-in-place wall. Casting concrete in the cavity increases the thickness of the wall, enhances its radiation-proof effect, does not require on-site formwork, avoids mold waste, and reduces construction costs. The integrity of the cast-in-place wall is also good, which can improve the strength and stability of the entire structure.

[0004] While the modular radiation-proof cavity wall of the aforementioned patent can increase the wall thickness while serving as a formwork for cast-in-place walls, thus avoiding mold waste, the modular radiation-proof cavity wall lacks the necessary positioning structure. This results in the modular radiation-proof cavity wall requiring measurement and positioning during assembly to prevent tilting or offsetting, making assembly of the modular radiation-proof cavity wall rather cumbersome. Furthermore, simply filling the modular radiation-proof cavity wall with concrete to increase the wall thickness as a radiation-proof layer results in poor radiation protection effectiveness.

[0005] Therefore, we made improvements to this and proposed a modular radiation-proof wall structure. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a modular radiation-proof wall structure, which solves the problems in the existing technology that the modular radiation-proof wall needs to be positioned during the assembly process and uses the increased thickness of the wall as a radiation-proof layer, resulting in poor radiation protection effect.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a modular radiation-proof wall structure, including a wall assembly, the wall assembly being a rectangular frame structure, a plurality of wall assemblies, and the plurality of wall assemblies being longitudinally overlapped and fixedly arranged to form a spatial structure with radiation-proof function; The wall assembly includes a first assembly block, a second assembly block and a wall assembly block.

The multiple wall assembly blocks are assembled between the first assembly blocks and the second assembly blocks. The first assembly blocks, the second assembly blocks and the wall assembly blocks are assembled to form a rectangular frame structure of the wall assembly.

[0008] As a preferred solution, the first assembly block, the second assembly block, and the wall assembly block are placed on the wall surface of the inner cavity of the wall assembly and overlapped with radiation-proof lead plates. The radiation-proof lead plates of the first assembly block and the second assembly block are V-shaped plate structures with an angle of 90°, and the radiation-proof lead plates of the wall assembly block are rectangular plate structures. Both sides of the radiation-proof lead plate of the second assembly block and one side of the radiation-proof lead plate of the wall assembly block are provided with engaging grooves; Sealing plates are provided on both sides of the radiation-proof lead plate of the first assembly block and on the other side of the radiation-proof lead plate of the wall assembly block; The sealing plate of the radiation-proof lead plate of the wall assembly block is tightly pressed into the fitting groove of the radiation-proof lead plate of the second assembly block adjacent thereto; The sealing plate of the radiation-proof lead plate of the first assembly block is tightly pressed into the fitting groove of the radiation-proof lead plate of the laterally adjacent wall assembly block; The sealing plate of the radiation-proof lead plate of the wall assembly block is tightly pressed into the fitting groove of the radiation-proof lead plate of the laterally adjacent wall assembly block.

[0009] As a preferred solution, a plug-in plate is fixedly provided on the upper part of the radiation-proof lead plate in a longitudinally offset manner. The shape of the plug-in plate is consistent with the cross-sectional shape of the radiation-proof lead plate. The plug-in plate is arranged close to the inner wall of the wall assembly. The distance between the bottom of the plug-in plate and the upper part of the radiation-proof lead plate is the same as the thickness of the radiation-proof lead plate. The plug-in plate is tightly pressed together with the bottom of the longitudinally adjacent radiation-proof lead plate.

[0010] As a preferred solution, filling cavities are provided at both ends and the middle of the first and second assembly blocks, and filling cavities are provided at both ends of the wall assembly block. The filling cavities are filled with concrete, and the longitudinally adjacent wall assemblies are fixed together by the concrete in the filling cavities. A sealing positioning frame is provided around the upper opening of the filling cavity, and a sealing positioning groove is provided around the lower opening of the filling cavity; The sealing positioning frames and sealing positioning grooves that are adjacent to each other in the longitudinal direction are inserted into each other.

[0011] As a preferred solution, the side walls at both ends of the first assembly block are longitudinally provided with positioning blocks, and the side walls at both ends of the second assembly block are longitudinally provided with positioning grooves; A positioning block is longitudinally provided on one end side wall of the wall assembly block, and a positioning groove is longitudinally provided on the other end side wall of the wall assembly block; The positioning block of the first assembly block is inserted into the positioning groove of the adjacent wall assembly block, the positioning groove of the second assembly block is fitted into the positioning block of the adjacent wall assembly block, and the positioning blocks and positioning grooves of the adjacent wall assembly blocks are inserted into each other.

[0012] As a preferred solution, the first assembly block, the second assembly block and the wall assembly block are placed on the wall surface of the wall assembly cavity and are fixed with screws in a transverse direction; The radiation-proof lead plate is connected to the wall surface corresponding to the screw rod and a lead cylinder is fixed thereon. The lead cylinder and the screw rod are passed through and fixedly connected to the bottom of the inner cavity of the lead cylinder through a nut.

[0014] As a preferred solution, the height of the plug-in plate is the same as the height of the sealing positioning frame.

[0015] The present invention has the following beneficial effects: The first assembly block and the second assembly block are spaced apart at the four corners of the wall assembly. With one of the first assembly block or the second assembly block as a base point, multiple wall assembly blocks are assembled and arranged between the first assembly block and the second assembly block to form a wall assembly. The positioning blocks and the positioning grooves laterally position the first assembly block, the second assembly block, and the wall assembly block so that the shape and structure of the assembled wall assembly will not shift. Then, the multiple wall assemblies are longitudinally overlapped and fixed. The sealing positioning frame and the sealing positioning groove longitudinally position the wall assembly to prevent the assembled and overlapped wall assemblies from tilting. The longitudinally adjacent filling cavities are positioned by the sealing positioning frame and the sealing positioning groove, so that the filling cavities are longitudinally overlapped and sealed, and then concrete is filled in the filling cavities, which not only increases the thickness of the wall assembly but also fixes the longitudinally adjacent wall assemblies; The radiation-proof lead plates placed on the inner wall of the wall assembly can increase the radiation-proof effect of the wall assembly, and the horizontally adjacent radiation-proof lead plates are pressed and sealed by the interlocking grooves and sealing plates, and the vertically adjacent radiation-proof lead plates are pressed and sealed by the plug-in plates to prevent gaps from being generated at the edges of adjacent radiation-proof lead plates, thereby further enhancing the radiation-proof effect of the wall assembly.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
