Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a radiation-proof reinforced concrete structure. Background Technology

[0002] In nuclear power plants, hospital radiology departments, laboratories, and other similar locations, radiation shielding structures are crucial for ensuring personnel safety and the normal operation of equipment. Traditional radiation shielding structures, which often utilize heavy concrete, present the following problems.

[0003] 1. Limited radiation protection performance: The radiation protection performance of traditional concrete structures mainly relies on the density and thickness of the material, which is insufficient to meet the needs of high-radiation environments. 2. Insufficient bonding strength between structural layers: The bonding strength between different concrete structural layers is weak, easily leading to interlayer delamination, affecting the overall structural stability and radiation protection effect.

[0004] Therefore, a radiation-resistant reinforced concrete structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a radiation-proof reinforced concrete structure in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A radiation-shielding reinforced concrete structure includes a concrete main body, which is composed of a reinforced concrete layer, a radiation-shielding concrete layer, and a regular concrete layer, arranged sequentially from the inside to the outside. The surface of the regular concrete layer is provided with an outer decorative component, the inner wall of which is filled with a lightweight radiation-shielding material. Both the surfaces of the reinforced concrete layer and the radiation-shielding concrete layer have roughening grooves, and both the surfaces of the reinforced concrete layer and the radiation-shielding concrete layer are provided with a wire mesh component.

[0008] Furthermore, the outer decorative component includes a horizontally mounted keel, the surface of the ordinary concrete layer is fixedly connected to the horizontally mounted keel, the surface of the ordinary concrete layer is fixedly connected to the vertically mounted keel, and decorative panels are fixedly connected to the surfaces of the horizontally mounted keel and the vertically mounted keel.

[0009] Furthermore, the hanging mesh assembly includes hook blocks disposed on the surfaces of the reinforced concrete layer and the radiation-shielding concrete layer, and the surface of the hook blocks is provided with metal mesh.

[0010] Furthermore, the reinforced concrete layer is a fiber-reinforced concrete layer, in which steel fibers and carbon fiber materials are added.

[0011] Furthermore, the radiation-shielding concrete layer is a high-density radiation-shielding concrete layer, and industrial waste such as fly ash and slag are added to the radiation-shielding concrete layer.

[0012] Furthermore, the lightweight radiation shielding material is a lightweight radiation shielding foam material containing boron polymer, and the lightweight radiation shielding material is filled in the hollow structure formed by the horizontally installed keel and the vertically installed keel.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The main body of the concrete structure of this utility model is a multi-layer composite structure. The outer decorative component blocks the external environment from eroding the ordinary concrete layer and enhances the aesthetics of the structure. The interior of the outer decorative component is filled with lightweight radiation-proof material, which further enhances the radiation protection performance of the structure. Through the multi-layer structural design and the optimization of the internal materials of the main concrete structure, a radiation-proof filling layer is set on the outside of the main concrete structure, thereby increasing the radiation protection performance of the structure.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a radiation-resistant reinforced concrete structure includes a main concrete structure 1, which is composed of a reinforced concrete layer 101, a radiation-resistant concrete layer 102, and a regular concrete layer 103. The reinforced concrete layer 101, radiation-resistant concrete layer 102, and regular concrete layer 103 are arranged sequentially from the inside out. An outer decorative component 2 is provided on the surface of the regular concrete layer 103, and the inner wall of the outer decorative component 2 is filled with a lightweight radiation-resistant material 3. Scraping grooves 4 are formed on the surfaces of both the reinforced concrete layer 101 and the radiation-resistant concrete layer 102, and wire mesh components 5 are provided on the surfaces of both. Specifically, in this radiation-resistant reinforced concrete structure, the main concrete structure 1 is a multi-layered composite structure, and its internal structure is optimized to improve its radiation resistance performance. Additionally, an outer decorative component 1 is provided on the exterior of the regular concrete layer 103. Component 2, the outer decorative component 2, acts as a physical barrier to prevent external environmental erosion of the ordinary concrete layer 103, extending the structural lifespan. The decorative material improves the building's appearance, making it more in line with the aesthetic requirements of modern architectural design. At the same time, lightweight radiation-shielding material 3 is filled inside the outer decorative component 2, further enhancing the structure's radiation protection performance. Through multi-layer structural design and optimization of the materials inside the concrete main body 1, a radiation-shielding filling layer is set on the outside of the concrete main body 1, thereby increasing the structure's radiation protection performance. When the concrete main body 1 is poured sequentially, the setting of the scraping groove 4 and the mesh component 5 increases the bonding force between the concrete main body 1 structures. The setting of the scraping groove 4 and the mesh component 5 enhances the bonding force between different structural layers, making it difficult for the layers to peel off, thus not affecting the overall structural stability and radiation protection effect.

[0026] like Figure 1 , Figure 4 As shown, the outer decorative component 2 includes a horizontally mounted keel 201. The horizontally mounted keel 201 is fixedly connected to the surface of the ordinary concrete layer 103, and a vertically mounted keel 202 is fixedly connected to the surface of the ordinary concrete layer 103. Decorative panels 203 are fixedly connected to the surfaces of the horizontally mounted keel 201 and the vertically mounted keel 202. Specifically, the outer decorative component 2 is designed so that the decorative panels 203 act as a physical barrier to block external environmental factors such as rain, ultraviolet rays, and temperature changes from eroding the ordinary concrete layer 103, thus extending the structural lifespan. The appearance of the building is improved by using finishing materials such as stone, metal plates, and paint, making it more in line with the aesthetic requirements of modern architectural design. The horizontally mounted keel 201 and the vertically mounted keel 202 are installed on the outer surface of the ordinary concrete layer 103 to install the decorative panels 203. Lightweight radiation-resistant material 3 is filled into the hollow structure formed by the horizontally mounted keel 201 and the vertically mounted keel 202 to further enhance the radiation resistance of the structure.

[0027] like Figure 2 , Figure 3 As shown, the mesh assembly 5 includes a hook block 501, which is disposed on the surface of the reinforced concrete layer 101 and the radiation-shielding concrete layer 102. The surface of the hook block 501 is provided with a metal mesh 502. Specifically, the mesh assembly 5 is used to improve the bonding force between different structural layers of the concrete structure 1. The rough surface or porous structure of the metal mesh 502 can increase the mechanical interlocking of the new and old concrete and improve the bonding force. At the same time, the mesh assembly 5 can also prevent the risk of radiation leakage caused by cracks and ensure the continuity of the shielding layer.

[0028] like Figure 2 As shown, the reinforced concrete layer 101 is a fiber-reinforced concrete layer, in which steel fibers and carbon fiber materials are added; specifically, steel fibers and carbon fibers are added to the concrete. The steel fibers have a diameter of 0.5-1.0 mm and a length of 20-50 mm, and the dosage is 1-2% of the concrete volume. The carbon fibers have a diameter of 5-10 micrometers and a length of 5-15 mm, and the dosage is 0.5-1% of the concrete volume. The addition of steel fibers and carbon fibers significantly improves the crack resistance of the concrete, reduces the generation and propagation of cracks, and enhances the tensile strength of the concrete, making it more stable under stress.

[0029] like Figure 2 As shown, the radiation-shielding concrete layer 102 is a high-density radiation-shielding concrete layer. Industrial waste such as fly ash and slag are added to the radiation-shielding concrete layer 102. Specifically, high-strength cement, fine aggregates such as quartz sand, and coarse aggregates such as barite are mixed in a certain proportion to ensure the basic strength and radiation-shielding performance of the concrete. Fly ash and slag are added to the concrete, with the fly ash content being 20-30% of the cement weight and the slag content being 10-20% of the cement weight. These industrial wastes not only improve the radiation-shielding performance of the concrete but also contribute to resource recycling. Simultaneously, the foam material has good thermal insulation properties, helping to maintain stable internal building temperatures and reduce energy consumption.

[0030] like Figure 4 As shown, the lightweight radiation shielding material 3 is a lightweight radiation shielding foam material containing boron polymer. The lightweight radiation shielding material 3 is filled in the hollow structure formed by the horizontal installation keel 201 and the vertical installation keel 202. Specifically, the boron polymer has a high absorption cross section for thermal neutrons, and the boron-containing polymer can effectively absorb neutrons, thus enabling the structure to be further treated for radiation protection.

[0031] In summary: This radiation-shielding reinforced concrete structure has a multi-layered composite main structure 1. The reinforced concrete layer 101 is the innermost layer. The reinforced concrete layer 101, the radiation-shielding concrete layer 102, and the ordinary concrete layer 103 are poured in layers sequentially. The reinforced concrete layer 101 enhances the overall strength of the structure, the radiation-shielding concrete layer 102 enhances the radiation protection performance, and the ordinary concrete layer 103 serves as the external protective base. Outside the ordinary concrete layer 103, through the installation of outer decorative components 2, horizontal and vertical keels 201 are installed on the outer surface of the ordinary concrete layer 103. Lightweight radiation-shielding material 3 is filled into the hollow structure formed by the horizontal and vertical keels 201 and 202, further enhancing the structure's radiation resistance. The decorative panel 203 blocks external environmental influences and enhances the structure's aesthetics. Scraping grooves 4 are installed on the surfaces of the reinforced concrete layer 101 and the radiation-shielding concrete layer 102. It can create an uneven, rough surface on the old concrete, increasing the contact area with the newly poured concrete. When pouring in layers, the hook block 501 connects the metal mesh 502 between different structural layers of the main concrete structure 1, thereby improving the adhesion between different layers and making the structure less prone to peeling and delamination.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
