Description

Technical Field

[0001] This utility model relates to the field of steel structure column reinforcement technology, specifically a reinforcement component for a steel structure column of a container. Background Technology

[0002] Steel structural column reinforcement components for shipping containers are key components used to enhance the load-bearing capacity and stability of the steel structural columns. They are designed to address safety hazards caused by heavy loads, harsh transportation environments, or structural aging. During long-term use, the steel structural columns of shipping containers are prone to strength reduction due to cargo compression, collisions, or corrosion. Reinforcement components are combined with the original steel columns through mechanical connections or welding to effectively improve their compressive and torsional resistance. However, existing reinforcement components have certain shortcomings.

[0003] For example, application number CN202221387519.6 describes a reinforcement component for a steel structure column of a container house, relating to the field of container house technology. This component includes a reinforcement member with a sealing rubber sleeve fitted on its outer side. Sunscreen boxes are fixed to both sides of the outer wall of the sealing rubber sleeve, and absorbent sponges are embedded inside the sunscreen boxes. This invention uses a sealing rubber sleeve on the outer side of the reinforcement member and absorbent sponges fixed to its outer wall. After the reinforcement is fixed, the sealing rubber sleeve and absorbent sponges can block sunlight, thereby reducing the temperature of the reinforcement member itself and preventing heat conduction to the interior of the container house. The use of absorbent sponges allows for the addition of cool water to the inside of the reinforcement member during hot weather, increasing its practicality. However, this reinforcement member is exposed to the external environment for extended periods and is susceptible to corrosion from rainwater and salt. The protective measures are ineffective, accelerating the corrosion of the steel structure column, reducing its strength and stability, and offering limited strength improvement. This may lead to reinforcement failure or exacerbate structural damage.

[0004] Therefore, in view of this, we studied and improved the existing structure to propose a reinforcement for the steel structure column of a container. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement component for the steel structure column of a container to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforcement component for a steel structure column of a container, comprising a steel structure column body and a multi-layer composite anti-corrosion structure, characterized in that the outer surface of the steel structure column body is fixedly connected to the multi-layer composite anti-corrosion structure, and the multi-layer composite anti-corrosion structure includes an epoxy zinc-rich primer layer fixedly connected to the outer surface of the steel structure column body, a zinc-aluminum alloy sacrificial anode layer fixedly connected to the outer surface of the epoxy zinc-rich primer layer, a fluorocarbon topcoat layer fixedly connected to the outer surface of the zinc-aluminum alloy sacrificial anode layer, and an anti-corrosion isolation film fixedly connected to the outer surface of the fluorocarbon topcoat layer.

[0007] Preferably, the outer surface of the main body of the steel structure column is fitted with an installation frame, and the inner surface of the installation frame is provided with a fastening groove.

[0008] Preferably, the inner surface of the fastening groove is threaded with fastening bolts, and a honeycomb sandwich reinforcement structure is fixedly connected to one side of the mounting frame.

[0009] Preferably, the honeycomb sandwich reinforcement structure includes a reinforcing frame fixedly connected to one side of the mounting frame, and a honeycomb core material is fixedly connected to the inner surface of the reinforcing frame. A structural adhesive is fixedly connected to one side of the honeycomb core material, and a composite steel plate is fixedly connected to one side of the structural adhesive.

[0010] Preferably, a limiting plate is fixedly connected to one side of the reinforcing frame, and a T-shaped groove is provided on the inner surface of the reinforcing frame.

[0011] Preferably, the inner surface of the T-shaped groove is slidably connected to a slider, and the inner surface of the slider is threadedly connected to a locating pin.

[0012] Preferably, the inner surface of the steel structure column body is provided with a guide rail, and the inner surface of the guide rail is fixedly connected with a shock-absorbing rubber pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model constructs a multi-layered, three-dimensional anti-corrosion system through the setting of a multi-layered composite anti-corrosion structure, effectively blocking the intrusion of oxygen, moisture and acid and alkali media. When external corrosive media penetrate the primer layer, the zinc-aluminum alloy, with its lower electrode potential, preferentially undergoes an oxidation reaction. Through its own "sacrifice," it transforms the main body of the steel structure column into the cathode of the battery, thereby avoiding corrosion. This layer of material has excellent weather resistance and can maintain stable sacrificial anode performance even in high temperature, high humidity or strong ultraviolet light environments, continuously providing long-term protection for the steel structure. Each layer of material performs its own function and works together to significantly improve the corrosion resistance of the steel structure column, effectively extend its service life, and reduce maintenance costs. It is especially suitable for container applications in highly corrosive environments such as marine transportation and chemical storage.

[0015] 2. This utility model improves the compressive strength and bending stiffness of steel structure columns by setting up a honeycomb sandwich reinforcement structure, significantly optimizing the strength-to-weight ratio of the structure. This triple mechanism of "core material dispersing stress + skin bearing load + adhesive layer synergistic effect" enables the honeycomb sandwich reinforcement structure to not only resist conventional static loads, but also effectively cope with dynamic loads under extreme conditions such as earthquakes and strong winds, greatly improving the reliability and safety of steel structure columns.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2As shown, a reinforcement component for a steel structural column of a container includes a steel structural column body 1 and a multi-layer composite anti-corrosion structure 2. The multi-layer composite anti-corrosion structure 2 is characterized in that the outer surface of the steel structural column body 1 is fixedly connected to the outer surface, and the multi-layer composite anti-corrosion structure 2 includes an epoxy zinc-rich primer layer 201 fixedly connected to the outer surface of the steel structural column body 1, a zinc-aluminum alloy sacrificial anode layer 202 fixedly connected to the outer surface of the epoxy zinc-rich primer layer 201, and a fluorocarbon topcoat layer 203 fixedly connected to the outer surface of the zinc-aluminum alloy sacrificial anode layer 202. The outer surface of the fluorocarbon topcoat layer 203 is fixedly connected with an anti-corrosion isolation film 204. The epoxy zinc-rich primer layer 201 forms a basic anti-corrosion barrier, isolating the metal from external corrosive media. The zinc-aluminum alloy sacrificial anode layer 202 uses electrochemical principles to preferentially corrode itself to protect the main body of the steel structure column 1. The zinc-aluminum alloy sacrificial anode layer 202 has excellent weather resistance and corrosion resistance, further protecting the internal structure. The fluorocarbon topcoat layer 203 prevents the zinc-aluminum alloy sacrificial anode layer 202 from directly contacting the anti-corrosion isolation film 204 and causing a chemical reaction.

[0023] like Figure 3 As shown, an installation frame 3 is fitted onto the outer surface of the steel structure column body 1, and a fastening groove 4 is provided on the inner surface of the installation frame 3. A fastening bolt 5 is threaded onto the inner surface of the fastening groove 4, and a honeycomb sandwich reinforcement structure 6 is fixedly connected to one side of the installation frame 3. A reinforcing shim is provided on the inner surface of the fastening groove 4. The fastening bolt 5 passes through the reinforcing shim and the fastening groove 4 and connects with the installation groove provided on the steel structure column body 1. No special tools are required, the operation is simple, and the connection strength between the installation frame 3 and the steel structure column body 1 is improved, effectively preventing the installation frame 3 from loosening.

[0024] Furthermore, the honeycomb sandwich reinforcement structure 6 includes a reinforcing frame 601 fixedly connected to one side of the mounting frame 3, and a honeycomb core material 602 is fixedly connected to the inner surface of the reinforcing frame 601. A structural adhesive 603 is fixedly connected to one side of the honeycomb core material 602, and a composite steel plate 604 is fixedly connected to one side of the structural adhesive 603. The honeycomb core material 602 has the characteristics of being lightweight and high-strength, which can effectively disperse stress and enhance the compressive and bending resistance of the main body of the steel structure column 1. The composite steel plate 604 further improves the overall stiffness and stability of the structure, and the structural adhesive 603 ensures a tight bond between the layers. Multiple protections enhance the strength of the main body of the steel structure column 1.

[0025] Furthermore, a limiting plate 7 is fixedly connected to one side of the reinforcing frame 601, and a T-shaped groove 8 is provided on the inner surface of the reinforcing frame 601. A slider 9 is slidably connected to the inner surface of the T-shaped groove 8, and a positioning pin 10 is threadedly connected to the inner surface of the slider 9. During installation, the reinforcing frame 601 is fitted onto the steel structure column body 1, and the slider 9 is pushed down along the T-shaped groove 8. One side of the slider 9 is tightly fitted with the steel structure column body 1. The positioning pin 10 is tightened to further fix the slider 9, so that it generates greater friction between itself and the steel structure column body 1, achieving a firm fixation.

[0026] Furthermore, a guide rail 11 is provided on the inner surface of the main body of the steel structure column 1, and a shock-absorbing rubber pad 12 is fixedly connected to the inner surface of the guide rail 11. The guide rail 11 is consistent with the mounting block of the container shell, and the shock-absorbing rubber pad 12 is tightly connected to the outer surface of the mounting block, which not only improves the stability of the container, but also ensures the sealing of the container.

[0027] Working principle: When using the steel structure column reinforcement components of this container, the surface of the main body 1 of the steel structure column is first ground and rust-removed to ensure a clean and flat surface, preparing for subsequent installation and anti-corrosion treatment. Then, an epoxy zinc-rich primer layer 201, a thermally sprayed zinc-aluminum alloy sacrificial anode layer 202, and a fluorocarbon topcoat layer 203 are sequentially sprayed onto the surface of the main body 1 of the steel structure column. Finally, an anti-corrosion isolation membrane 204 is laid, completing the construction of the multi-layer composite anti-corrosion structure 2. Then, a composite steel plate 604 is applied. The reinforcing frame 601 of the honeycomb sandwich reinforced structure 6 is sleeved on the outer surface of the steel structure column body 1. The slider 9 is pushed down along the T-shaped slide groove 8, and the positioning pin 10 is tightened to achieve initial fixation. Then, the steel structure column body 1 is sleeved on the inner surface of the mounting frame 3, and the fastening bolts 5 inside the fastening groove 4 are tightened to connect multiple sets of steel structure column bodies 1 to each other. Finally, the container is connected to the steel structure column body 1 through the shock-absorbing rubber pad 12 inside the guide rail 11 and other connecting components. This is the working principle of the steel structure column reinforcement of the container.
