Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a reinforced concrete anti-corrosion and reinforcement device. Background Technology

[0002] Reinforced concrete is a composite material made by adding steel bars, steel mesh, steel plates, or fibers to concrete. These components work together to improve the mechanical properties of concrete. The main purpose of reinforced concrete is to increase its tensile strength and shear capacity. It is commonly used in building structures. However, in saline-alkali underground structures, coastal buildings, and road and bridge structures treated with de-icing agents, reinforced concrete structures exposed to corrosive environments are prone to steel bar corrosion, leading to concrete cracking and spalling, and even loss of load-bearing steel, thus reducing the durability of the concrete structure. To improve the efficiency of reinforced concrete use, an anti-corrosion reinforcement device is needed. However, existing anti-corrosion reinforcement devices still have the following shortcomings:

[0003] When existing anti-corrosion reinforcement devices are used, most of them only reinforce reinforced concrete through a single structure. This can affect the use of reinforced concrete in relatively harsh environments, resulting in a decrease in the practicality and efficiency of the anti-corrosion reinforcement devices.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its deficiencies, and proposed a reinforced concrete anti-corrosion reinforcement device. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforced concrete anti-corrosion and reinforcement device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforced concrete anti-corrosion reinforcement device, comprising a reinforced concrete body, a carbon fiber plate body, and a steel plate body. The reinforced concrete body is provided with a carbon fiber plate body on the outside, and a steel plate body is added on the outside of the carbon fiber plate body. A threaded mounting groove is opened inside the steel plate body, and a mounting bolt is connected inside the threaded mounting groove. A sealing ring is added on the outside of the mounting bolt. A reinforcing bar body is provided inside the reinforced concrete body, and an epoxy resin coating is added on the outside of the reinforcing bar body. A neoprene rubber coating is added on the outside of the epoxy resin coating.

[0007] Furthermore, the outer side of the carbon fiber plate body is horizontally distributed with the outer side of the reinforced concrete body, and the carbon fiber plate body is fixedly connected to the reinforced concrete body by structural adhesive.

[0008] Furthermore, the outer sides of the steel plate body and the outer sides of the carbon fiber plate body are horizontally distributed, and the outer sides of the steel plate body and the outer sides of the carbon fiber plate body are closely attached to each other.

[0009] Furthermore, the internal dimensions of the threaded mounting groove are adapted to the external dimensions of the mounting bolt, and the mounting bolt is rotatably connected to the steel plate body through the threaded mounting groove.

[0010] Furthermore, the external dimensions of the mounting bolt are adapted to the internal dimensions of the sealing ring, and the mounting bolt and the sealing ring are embedded in each other.

[0011] Furthermore, the number of sealing rings is set to eight, and four sealing rings are arranged as a group, and each group of sealing rings is symmetrically arranged on both sides of the outside of the reinforced concrete body with respect to the central axis of the side of the reinforced concrete body.

[0012] Furthermore, the steel bar body is embedded in the reinforced concrete body, and the steel bar body is fixedly connected to the reinforced concrete body.

[0013] Furthermore, the outer side of the main steel bar and the outer side of the epoxy resin coating are horizontally distributed, and the outer side of the main steel bar and the outer side of the epoxy resin coating are closely attached.

[0014] This utility model provides a reinforced concrete corrosion protection and strengthening device, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the carbon fiber plate body, enables the carbon fiber plate body to be pasted to the upper and lower surfaces of the reinforced concrete body using structural adhesive when the reinforced concrete anti-corrosion reinforcement device is used, thereby improving the stress performance of the component. At the same time, the steel plate body is butt-mounted on the outside of the carbon fiber plate body and fixed on the outside of the reinforced concrete body using mounting bolts. The steel plate body enhances the bending and shear resistance of the reinforced concrete body. Furthermore, before the mounting bolts are installed, a sealing ring is fitted on the outside of the mounting bolts, thereby increasing the stability of the mounting bolts after installation and improving the stability of the reinforced concrete during use.

[0016] 2. This utility model, through the application of an epoxy resin coating, enables the use of reinforced concrete anti-corrosion reinforcement devices. An epoxy resin coating is then applied to the exterior of the reinforcing steel, forming a robust protective film that improves the steel's corrosion resistance. Simultaneously, a neoprene rubber coating is added outside the epoxy resin coating. This neoprene rubber coating possesses excellent weather resistance and toughness, effectively absorbing moisture from the surface of the reinforcing steel and preventing rust. This enhances the overall practicality and efficiency of the anti-corrosion reinforcement device. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3As shown, a reinforced concrete anti-corrosion reinforcement device includes a reinforced concrete body 1, a carbon fiber plate body 2, and a steel plate body 3. The carbon fiber plate body 2 is disposed outside the reinforced concrete body 1, and the steel plate body 3 is additionally disposed outside the carbon fiber plate body 2. A threaded mounting groove 4 is formed inside the steel plate body 3, and a mounting bolt 5 is connected inside the threaded mounting groove 4. A sealing ring 6 is added to the outside of the mounting bolt 5. The outer side of the carbon fiber plate body 2 is horizontally distributed with the outer side of the reinforced concrete body 1, and the carbon fiber plate body 2 is fixedly connected to the reinforced concrete body 1 by structural adhesive. The outer side of the steel plate body 3 is horizontally distributed with the outer side of the carbon fiber plate body 2, and the outer side of the steel plate body 3 is tightly fitted to the outer side of the carbon fiber plate body 2. The internal dimensions of the threaded mounting groove 4 are adapted to the external dimensions of the mounting bolt 5, and the mounting bolt 5 is rotatably connected to the steel plate body 3 through the threaded mounting groove 4. The external dimensions of the mounting bolt 5 are adapted to the internal dimensions of the sealing ring 6, and the mounting bolt 5 and the sealing ring 6 are embedded. The connection uses a method where eight sealing rings 6 are provided, with four sealing rings 6 forming a group. Each group of sealing rings 6 is symmetrically arranged on both sides of the reinforced concrete main body 1 along its side centerline. The carbon fiber plate main body 2 is bonded to the upper and lower surfaces of the reinforced concrete main body 1 using structural adhesive, thereby improving the structural performance of the component. Simultaneously, the steel plate main body 3 is butt-fitted onto the outside of the carbon fiber plate main body 2. The internal dimensions of the threaded mounting groove 4 inside the steel plate main body 3 are adapted to the external dimensions of the mounting bolt 5, allowing the mounting bolt 5 to be rotated and installed into the steel plate main body 3 through the threaded mounting groove 4. The steel plate main body 3 is then fixed to the outside of the reinforced concrete main body 1 using the mounting bolt 5. The steel plate main body 3 enhances the bending and shear resistance of the reinforced concrete main body 1. Before the mounting bolt 5 is installed, the sealing rings 6 are fitted onto the outside of the mounting bolt 5, thereby increasing the stability of the mounting bolt 5 after installation and improving the stability of the reinforced concrete during use.

[0023] like Figure 1 and Figure 3As shown, a steel reinforcement body 7 is installed inside the reinforced concrete body 1, and an epoxy resin coating 8 is added to the outside of the steel reinforcement body 7. A neoprene rubber coating 9 is then applied to the outside of the epoxy resin coating 8. The steel reinforcement body 7 is embedded in and fixedly connected to the reinforced concrete body 1. The outer sides of the steel reinforcement body 7 and the epoxy resin coating 8 are horizontally distributed and tightly adhered to each other. Before pouring the reinforced concrete body 1, the steel reinforcement body 7 is placed inside the reinforced concrete body 1. Simultaneously, silica fume, fly ash, or finely ground slag are added to the concrete to reduce the permeability of corrosive media and improve the concrete's impermeability. The epoxy resin coating 8 forms a strong protective film on the outside of the steel reinforcement body 7, thereby improving the corrosion resistance of the steel. The neoprene rubber coating 9, with its good weather resistance and toughness, can fully absorb moisture from the surface of the steel reinforcement body 7, preventing rust and thus improving the overall practicality and efficiency of the anti-corrosion reinforcement device.

[0024] In summary, this reinforced concrete corrosion protection and reinforcement device, when in use, firstly, uses structural adhesive to bond the carbon fiber plate body 2 to the upper and lower surfaces of the reinforced concrete body 1, thereby improving the structural performance of the component. Simultaneously, the steel plate body 3 is butt-fitted onto the outside of the carbon fiber plate body 2, and then fixed to the outside of the reinforced concrete body 1 using mounting bolts 5. The steel plate body 3 enhances the bending and shear resistance of the reinforced concrete body 1. Furthermore, before installing the mounting bolts 5, a sealing ring 6 is fitted onto the outside of the mounting bolts 5, thereby increasing the stability of the mounting bolts 5 after installation. Next, silica fume, fly ash, or finely ground slag are added to the concrete to reduce the permeability of corrosive media and improve the concrete's impermeability. At the same time, an epoxy resin coating 8 is added to the outside of the main steel reinforcement 7. The epoxy resin coating 8 forms a strong protective film on the outside of the main steel reinforcement 7, thereby improving the corrosion resistance of the steel reinforcement. In addition, a neoprene rubber coating 9 is added to the outside of the epoxy resin coating 8. The neoprene rubber coating 9 has good weather resistance and toughness and can fully absorb the moisture on the surface of the main steel reinforcement 7 to prevent the steel reinforcement from rusting, thereby improving the overall practicality and efficiency of the anti-corrosion reinforcement device.
