Description

Technical Field

[0001] This utility model relates to the field of concrete wall structure technology, and in particular to a radiation-proof and self-waterproof reinforced concrete wall structure. Background Technology

[0002] Reinforced concrete wall structures are composite wall systems with steel reinforcement as the framework and concrete as the matrix. Their core structure involves pre-embedding vertical and horizontal steel bars during concrete pouring to form a spatial grid-like framework, which shares the load through the bond between the steel bars and concrete.

[0003] The radiation-shielding, self-waterproof reinforced concrete wall structure effectively shields against gamma rays, X-rays, and neutron radiation. Radiation-shielding panels and waterproof coatings can be added to the surface, secured with threaded cylinders and bolts to form a multi-layered protection system. This structure combines radiation protection and self-waterproofing, making it suitable for high-radiation environments such as nuclear power plants and hospital radiology departments, meeting both safety and structural durability requirements.

[0004] An existing type of radiation-proof, self-waterproof reinforced concrete wall structure requires the use of high-density concrete in addition to the addition of radiation-proof materials during construction to ensure its radiation-proof function. However, using high-density concrete for the entire front wall would result in excessive self-weight of the wall, increasing the strength requirements of the foundation and reducing its seismic resistance. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a radiation-proof and self-waterproof reinforced concrete wall structure to solve the above-mentioned shortcomings in the prior art.

[0006] Technical solution: A radiation-proof and self-waterproof reinforced concrete wall structure, comprising a concrete wall body, wherein the concrete wall body has two partition layers inside, and a radiation-proof layer is provided between the two partition layers.

[0007] As a further description of the above technical solution: load-bearing columns are provided at both ends of the concrete wall body, and support components are provided inside the concrete wall and the load-bearing columns.

[0008] As a further description of the above technical solution: the support component includes multiple main bars, which are arranged perpendicularly to the ground inside the concrete wall body and the load-bearing column, and steel hoops are fitted on the multiple main bars.

[0009] As a further description of the above technical solution: the steel reinforcement hoops are staggered inside the concrete wall body.

[0010] As a further description of the above technical solution: the separation layer is composed of multiple separation plates.

[0011] As a further description of the above technical solution: each of the main reinforcing bars inside the concrete wall body is fitted with an installation frame, and each of the installation frames is fixedly mounted with a connecting rail. A plurality of connecting blocks are fixedly mounted on the partition plate, and the plurality of connecting blocks are slidably engaged with the plurality of connecting rails respectively.

[0012] As a further description of the above technical solution: the top of the plurality of partition plates is fixedly connected with a snap-fit ​​post, and the bottom of the plurality of partition plates is provided with a snap-fit ​​groove, which is located directly below the snap-fit ​​post.

[0013] As a further description of the above technical solution: a rubber pad is fixedly installed at the part where the partition plate contacts the reinforcing bar hoop.

[0014] Beneficial Effects: During wall construction, a radiation-shielding layer is created within the concrete wall body to provide radiation protection. This layer, primarily composed of high-density concrete substrate and composite shielding materials, is poured into the concrete. The high-density concrete uses high-density aggregates such as barite and magnetite, combined with admixtures like boron compounds and polyethylene particles to enhance shielding against gamma rays and neutrons. The two surface layers of the concrete wall body utilize a low water-cement ratio, silica fume / nano silica admixtures, and steel / polypropylene fiber reinforcement to reduce porosity and increase tensile strength. The surface waterproofing reinforcement layer employs cement-based penetrating crystalline waterproofing agents, silane / siloxane impregnating agents, and polyurea elastomers to achieve pore sealing, water repellency, and deformation adaptability. The waterproofing design utilizes waterstops and grouting pipes to ensure sealing of construction joints and subsequent leak repair. This invention ensures that the concrete wall body, while maintaining radiation protection, has a significantly lower self-weight than a concrete wall composed entirely of high-density concrete.

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-7 A radiation-proof, self-waterproof reinforced concrete wall structure includes a concrete wall body 1. The concrete wall body 1 has two internal partition layers 2, with a radiation-proof layer 3 positioned between the two partition layers 2. During wall construction, the radiation-proof layer 3 is created within the concrete wall body 1 to provide radiation protection. The radiation-proof layer 3 is cast within the concrete wall body 1. The material of the radiation-proof layer 3 mainly comprises a high-density concrete substrate and a composite shielding material. The high-density concrete uses high-density aggregates such as barite and magnetite, combined with admixtures such as boron compounds and polyethylene particles to enhance protection against gamma rays and neutrons. The shielding effect is achieved by using two layers of low water-cement ratio, silica fume / nano silica admixture, and steel / polypropylene fiber reinforcement on the surface of the concrete wall body to reduce porosity and increase tensile strength. The surface waterproof reinforcement layer uses cement-based penetrating crystalline waterproofing agent, silane / siloxane impregnating agent and polyurea elastomer to achieve pore blocking, water repellency and deformation adaptation. The waterproof design uses waterstops and grouting pipes to ensure the sealing of construction joints and subsequent leakage repair. Through this utility model, the concrete wall body 1 can ensure radiation protection while the self-weight of the wall body is much less than that of the concrete wall body 1 composed entirely of high-density concrete.

[0026] As a preferred technical solution in this embodiment, load-bearing columns 4 are provided at both ends of the concrete wall body 1, and support components are provided inside the concrete wall and the load-bearing columns 4. The role of the load-bearing columns 4 in the concrete wall is to share the vertical load and enhance the structural stability. By bearing part of the building's self-weight and live load, the direct pressure burden on the wall is reduced, and the risk of wall cracking or instability is reduced. At the same time, the load-bearing columns 4 and the wall work together to form a spatial force system, jointly resisting horizontal forces and improving the overall structural bearing capacity and seismic performance.

[0027] As a preferred technical solution of this embodiment, the support component includes a plurality of main reinforcing bars 5, which are arranged perpendicularly to the ground inside the concrete wall body 1 and the load-bearing column 4, and steel hoops 6 are fitted on the plurality of main reinforcing bars 5; when the concrete wall body 1 is constructed, the four main reinforcing bars 5 are reinforced by fitting steel hoops 6 on the four main reinforcing bars 5 as a group, and the main reinforcing bars 5 and the steel hoops 6 are connected by steel wire winding, and a plurality of steel hoops 6 are fitted on every four adjacent main reinforcing bars 5.

[0028] As a preferred technical solution in this embodiment, the steel reinforcement hoops 6 are staggered inside the concrete wall body 1. Since the length of the concrete wall body 1 is much greater than the length of the load-bearing column 4, the number of main reinforcement bars 5 inside the concrete wall body 1 is also much greater than the number of main reinforcement bars 5 inside the load-bearing column 4. Therefore, inside the concrete wall body 1, in addition to the steel reinforcement hoops 6 being fitted on the main reinforcement bars 5 in groups of four, multiple steel reinforcement hoops 6 are also fitted on the four main reinforcement bars 5 that are close to each other in two adjacent groups of main reinforcement bar 5 components, so as to connect multiple independent groups of main reinforcement bar 5 components together and increase the integrity of the concrete wall body 1.

[0029] As a preferred technical solution in this embodiment, the partition layer 2 is composed of multiple partition plates 10. Since the wall frame needs to be reinforced by steel hoops 6 during construction, the partition layer 2 is divided into multiple partition plates 10 to facilitate the installation of the steel hoops 6, and the steel hoops 6 are set between two adjacent partition plates 10.

[0030] As a preferred technical solution of this embodiment, each of the main reinforcing bars 5 inside the concrete wall body 1 is fitted with an installation frame 7, and each of the installation frames 7 is fixedly installed with a connecting rail 8. Each of the partition plates 10 is fixedly installed with a plurality of connecting blocks 9, and the plurality of connecting blocks 9 are slidably engaged with the plurality of connecting rails 8 respectively. The partition plate 10 is installed by means of the installation frames 7 and the connecting rails 8, which facilitates the rapid formation of the radiation shielding layer 3.

[0031] As a preferred technical solution of this embodiment, the top of the plurality of partition plates 10 is fixedly connected with a snap-fit ​​post 11, and the bottom of the plurality of partition plates 10 is provided with a snap-fit ​​groove 12, which is located directly below the snap-fit ​​post 11; the snap-fit ​​post 11 and the snap-fit ​​groove 12 on two adjacent partition plates 10 are interlocked and connected to each other, forming a partition layer 2 inside the concrete wall body 1.

[0032] As a preferred technical solution in this embodiment, a rubber pad 13 is fixedly installed at the part where the partition plate 10 contacts the reinforcing bar hoop 6; the rubber pad 13 increases the friction between the reinforcing bar hoop 6 and the rubber pad 13, making the reinforcing bar hoop 6 more stable.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
