Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a reinforced steel structure with an improved structural form. Background Technology

[0002] Steel structures are structural systems made primarily of steel, assembled from components such as steel profiles and plates through welding, bolting, and other methods. They are characterized by high strength, light weight, fast construction, good seismic resistance, and recyclability, and are widely used in industrial plants, large-span buildings, high-rise buildings, and bridges. They are an important, efficient, and flexible structural form in modern engineering construction.

[0003] In the complex environment of ocean waves, traditional steel structures, due to limitations in structural design, are unable to effectively cope with the continuous scouring and impact of ocean waves. Their planar or simple curved surface designs cannot reasonably divert the scouring force of seawater, and are prone to forming turbulence in local areas, leading to stress concentration. This causes local wear to intensify, and the impact resistance and stability to drop significantly. After being subjected to ocean waves for a long time, traditional steel structures are prone to deformation and damage due to excessive local stress, and may even affect the overall structural safety. They are not suitable for the harsh environment of frequent ocean waves. Utility Model Content

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an improved reinforced steel structure, solving the problem that traditional steel structures, due to their structural design limitations, are unable to effectively cope with the continuous scouring and impact of waves in complex environments subjected to ocean wave impacts. Their planar or simple curved surface designs cannot reasonably divert the scouring force of seawater, easily forming turbulence in local areas, leading to stress concentration, which intensifies local wear and significantly reduces impact resistance and stability. After long-term exposure to ocean wave impacts, traditional steel structures are prone to deformation and damage due to excessive local stress, even affecting the overall structural safety, making them unsuitable for the harsh environment of frequent ocean wave impacts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An improved reinforced steel structure includes a main steel structure body with an arc-shaped buffer layer fixedly installed on it. The arc-shaped buffer layer is located on the side of the main steel structure body facing the waves. A trapezoidal fixing groove is formed on the arc-shaped buffer layer, and a limiting fixing block is slidably installed inside the trapezoidal fixing groove. An arc-shaped replacement plate is fixedly installed on the limiting fixing block. The arc-shaped replacement plate and the arc-shaped buffer layer are combined to form an arc-shaped surface. A fixing slider is provided on the arc-shaped replacement plate, and a fixing base is provided on the arc-shaped buffer layer. Fixing holes are provided on the fixing base and the fixing slider.

[0006] Preferably, the arc-shaped replacement plate is provided with at least five annular rotating bases, which are arranged in two rows on the arc-shaped replacement plate, with both rows of annular rotating bases arranged from long to short. Each annular rotating base is rotatably mounted with an annular rotating shaft, one end of which extends out of the annular rotating base. Each annular rotating shaft is rotatably mounted with a wave-shaped spoiler. A sealed space is provided between the arc-shaped buffer layer and the main steel structure. A safety monitoring sensor is fixedly installed on the main steel structure, and the safety monitoring sensor is installed in the sealed space between the main steel structure and the arc-shaped buffer layer.

[0007] Preferably, the arc-shaped replacement plate is fixedly installed with at least three support columns, and a corrosion-inhibiting inner plate is fixedly installed on the support columns. The corrosion-inhibiting inner plate has a sandwich layer in the middle, and the sandwich layer in the corrosion-inhibiting inner plate is filled with corrosion inhibitor gel. The corrosion-inhibiting inner plate has a buffer guide hole, and a lightweight ceramic ball is placed in the buffer guide hole. An outer protective guide plate is fixedly installed on the corrosion-inhibiting inner plate, and a pressure sensor is provided on the outer protective guide plate. The outer protective guide plate has several outer anti-adhesion micro-flow holes.

[0008] The beneficial effects of the technical solutions provided in this application include at least the following: In this new invention, a steel structure main body, an arc-shaped buffer layer, and an arc-shaped replacement plate are combined to form an arc-shaped surface with a central angle of 75°. The arc-shaped buffer layer is fixed to the wave-facing side of the steel structure main body and forms a complete arc structure with the arc-shaped replacement plate. This can effectively divert the seawater scouring force, disperse the stress generated by the impact of the waves, and reduce local turbulence and stress concentration. Attached Figure Description

[0012] This application provides an improved reinforced steel structure that effectively solves the technical problem that traditional steel structures, due to their structural design limitations, cannot effectively cope with the continuous scouring and impact of waves in complex environments subjected to ocean wave impacts. Their planar or simple curved surface designs cannot reasonably divert the scouring force of seawater, easily forming turbulence in local areas, leading to stress concentration, which intensifies local wear, significantly reduces impact resistance and stability, and after long-term exposure to ocean wave impacts, traditional steel structures are prone to deformation and damage due to excessive local stress, even affecting the overall structural safety, making them unsuitable for the harsh environment of frequent ocean wave impacts. Example

[0013] like Figures 1-9 As shown, the technical solution in this application aims to effectively address the problem that traditional steel structures, due to their structural design limitations, are unable to effectively cope with the continuous scouring and impact of waves in complex environments subjected to ocean wave impacts. Their planar or simple curved surface designs cannot reasonably divert the scouring force of seawater, easily forming turbulence in localized areas, leading to stress concentration, which intensifies localized wear, significantly reduces impact resistance and stability, and after long-term exposure to ocean wave impacts, traditional steel structures are prone to deformation and damage due to excessive localized stress, even affecting the overall structural safety. This makes them unsuitable for the harsh environment of frequent ocean wave impacts. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides an improved reinforced steel structure, including a main steel structure 1. The main steel structure 1 is an I-shaped steel member, with the seawater-contacting side made of low-alloy high-strength corrosion-resistant steel. The surface is smooth and the corners are rounded. An arc-shaped buffer layer 2 is fixedly installed on the main steel structure 1, positioned on the side facing the waves to adapt to the wave impact environment. A trapezoidal fixing groove 4 is provided on the arc-shaped buffer layer 2, which has a design that is wider at the inside and narrower at the outside. A limiting fixing block 5 is slidably installed inside the trapezoidal fixing groove 4, and an arc-shaped replacement plate 3 is fixedly installed on the limiting fixing block 5. The arc-shaped replacement plate 3 and the arc-shaped buffer layer 2 are combined into one. The arc-shaped surface, with a central angle of 75°, effectively diverts the scouring force of seawater underwater, reducing local turbulence and stress concentration. The arc-shaped replacement plate 3 is equipped with a fixed slider 11, and the arc-shaped buffer layer 2 is equipped with a fixed base 10. The fixed base 10 and the fixed slider 11 are equipped with fixing holes. When the arc-shaped replacement plate 3 is embedded in the arc-shaped buffer layer 2, it is connected by high-strength bolts through the fixing holes on the fixed base 10 and the fixed slider 11. The arc-shaped steel structure composed of the main steel structure 1, the arc-shaped buffer layer 2, and the arc-shaped replacement plate 3 can divert the scouring force of seawater, disperse the stress generated by deep-sea water pressure, reduce local wear and stress concentration, enhance the impact resistance and stability of the overall structure, and adapt to the complex deep-sea environment. Example

[0014] Based on Example 1, such as Figure 1 , Figure 2 Figure 4 ,and Figure 6As shown, the arc-shaped replacement plate 3 is equipped with at least five annular rotating bases 6. The annular rotating bases 6 are arranged in two rows on the arc-shaped replacement plate 3, with both rows arranged from longest to shortest. Each annular rotating base 6 has an annular rotating shaft 7 rotatably installed inside it. One end of the annular rotating shaft 7 extends out of the annular rotating base 6. Each annular rotating shaft 7 has a wave-shaped spoiler 8 rotatably installed on it. The wave-shaped spoiler 8 is a thin plate structure made of aluminum alloy with a continuous sinusoidal undulating shape and a polyurea anti-corrosion coating on its surface. The wave-shaped spoiler 8 is used to disrupt the periodic vortices generated by wave impact. The combination of the wave-shaped spoiler 8, the annular rotating shaft 7, and the annular rotating base 6 can guide the water flow on the seabed to form multi-directional turbulence using the wave-shaped curved surface. The wave-shaped spoiler 8 can swing with the waves, which can buffer the wave impact, disrupt its periodicity, and reduce the load of the wave impact on the steel structure body 1. At the same time, the swinging scouring reduces the attachment of marine organisms. A sealed space is opened between the arc-shaped buffer layer 2 and the steel structure body 1. A safety monitoring sensor 9 is installed in the sealed space between the main steel structure 1 and the arc-shaped buffer layer 2. The safety monitoring sensor 9 is a titanium alloy electrode sensor (its working principle is as follows: the sensor contains spaced titanium alloy electrode plates, which are normally in an open circuit state because there is no conductive medium between the electrodes. When a conductive medium, such as liquid or conductive substance, enters the electrode gap, the medium makes the electrode form a conductive path, causing detectable changes in electrical parameters such as current and resistance in the circuit. These changes are converted into electrical signal output, thereby realizing the monitoring of the presence of conductive medium). When the external arc-shaped buffer layer 2 and arc-shaped replacement plate 3 are damaged by seawater erosion, seawater will enter the sealed space between the main steel structure 1 and the arc-shaped buffer layer 2. When seawater enters, it acts as a conductive medium, making the electrode plates in the safety monitoring sensor 9 form a path, causing changes in current or resistance in the circuit, which are then converted into electrical signal output and transmitted to the receiver to prompt the staff that the steel structure in this area needs to be reinforced or replaced. Example

[0015] Based on the first embodiment, such as Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, at least three support columns 12 are fixedly installed on the arc-shaped replacement plate 3. A corrosion-inhibiting inner plate 13 is fixedly installed on each support column 12. The inner plate 13 has a sandwich layer in the middle, filled with polyethylene glycol-based zinc salt corrosion inhibitor gel. When the inner plate 13 is damaged by seawater erosion, the corrosion inhibitor gel slowly seeps out through micro-cracks, forming a protective film on the structural surface to reduce the corrosion rate. The inner plate 13 has buffer drainage holes 14, each containing lightweight ceramic balls. These lightweight ceramic balls can achieve a "particle support effect." The local stress under the superposition of wave impact and high pressure is addressed by fixing an outer protective guide plate 15 on the corrosion-inhibiting inner plate 13. The outer protective guide plate 15 is equipped with a pressure sensor, which can detect wave pressure, monitor the dynamics of wave impact load in real time, and provide timely warning of overload risk to ensure structural safety. The outer protective guide plate 15 is provided with several outer anti-adhesion micro-flow holes 16, which are used to form micro-jet scouring of the interlayer and main body surface to reduce marine organism attachment and provide water flow channels for environmental parameter monitoring.

[0016] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
