Description

Technical Field

[0001] The invention relates to the technical field of steel structures, in particular to a novel high-strength and corrosion-resistant steel structure. Background Art

[0002] In coastal areas, steel structures are widely used in various construction projects due to their high strength, good plasticity and processability, especially the lateral support beams of bridges.

[0003] However, there are still some problems with the existing steel structures. First, due to the humid coastal environment and high humidity, water film is easily formed on the surface of the steel structure. A large amount of chloride ions in the seawater are attached with water vapor, and the chloride ions are highly corrosive. They can penetrate the protective layer and react with steel to form rust. The rust has a large volume and produces expansion stress that causes the protective layer to peel off and accelerates the corrosion of the steel. This not only weakens the cross-sectional size of the steel structure and reduces its bearing capacity, but also makes the surface rough, increases wind resistance and water flow resistance, and affects the stability of the structure.

[0004] At the same time, strong ultraviolet radiation cannot be ignored. Due to the high energy of ultraviolet rays, they will destroy the organic molecular structure of the protective coating on the surface of the steel structure, causing it to age, crack or even fall off. After losing the protective coating, the steel structure is more susceptible to corrosion and oxidation. Long-term radiation will lead to a decrease in mechanical properties. In a bridge environment, this decrease in mechanical properties will make the transverse support beam more susceptible to deformation and other problems when facing complex stress conditions.

[0005] Therefore, under the combined influence of moisture and ultraviolet rays, the upper and lower flanges of the I-beam are prone to bending and deformation. Specifically, corrosion reduces the cross-sectional size of the flange and reduces its bending resistance, while ultraviolet rays degrade the material properties and reduce its strength and stiffness. When vehicles are driving on the bridge, the transverse support beams will bear dynamic loads. Coupled with the combined effects of wind loads, self-weight and other forces, the flanges are more likely to bend, which will affect the I-beam's stress-bearing performance and the overall stability of the structure, and thus affect the normal use of the bridge.

[0006] In order to improve the strength and stability of steel structures, the existing technology often sets reinforcing ribs to increase the moment of inertia of the section and improve the bending and torsion resistance. However, the reinforcing ribs will limit the deformation capacity of the steel structure, making it difficult to deform the steel structure and stimulate internal stress. Exceeding the yield strength will lead to local yield and plastic deformation, weakening the bearing capacity and accelerating aging damage. Secondly, the connection between the reinforcing rib and the main body will produce sudden stress changes due to different materials and geometric shapes, resulting in stress concentration, which is easy to cause fatigue cracks. As the cracks develop, the strength of the connection part decreases, which may cause the reinforcing rib to separate from the main body, affecting the overall stability of the structure.

[0007] Secondly, in humid areas, the flow state of air is affected by a variety of factors, and usually shows a tendency to flow parallel or downward, while there are relatively few upward air flows. This is mainly because the evaporation of water vapor near the ground in humid areas is large, the air humidity is high and the temperature is relatively high, forming a relatively stable warm and humid air layer. According to the thermal convection principle of hot air rising and cold air sinking, warm and humid air tends to rise, and the surrounding colder air will replenish it. In this process, the cold air mostly flows parallel to the ground or flows downward to fill the space left after the warm and humid air rises, resulting in relatively less upward air flows.

[0008] When the airflow flows through the I-beam in parallel, the shape of the bottom of the upper flange of the I-beam will change suddenly, which will interfere with the original flow state of the airflow and cause boundary layer separation. In this process, a low-speed vortex area will be formed. In the vortex area, the airflow speed is significantly reduced. The ability of the airflow to carry dust and impurities is closely related to the airflow speed. When the speed is reduced, its carrying capacity is also weakened. In this way, the dust and impurities that originally moved with the airflow are easy to settle and accumulate in this vortex area.

[0009] When the airflow flows downward, a certain windward surface will be formed at the upper flange of the I-beam. When the dust and impurities in the airflow encounter the obstruction of the upper flange during the forward movement, some of the dust and impurities will adhere to the surface of the upper flange. Since there is less upward airflow, it is difficult to effectively carry and remove the dust and impurities that have attached and accumulated on the upper flange, which makes it easier for dust and impurities to accumulate on the upper flange.

[0010] Since dust and impurities contain various corrosive substances, in a humid environment, these corrosive substances will accelerate the corrosion process of the I-beam, thereby reducing its strength and durability. This will not only increase the maintenance cost of the I-beam, but may even endanger the safety of the entire structure.

[0011] To this end, the present invention proposes a novel high-strength and corrosion-resistant steel structure. Summary of the invention

[0012] The purpose of the present invention is to provide a new type of high-strength and corrosion-resistant steel structure to solve the problems raised in the above background technology.

[0013] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel high-strength and corrosion-resistant steel structure, comprising an I-beam, a plurality of reinforcing ribs are installed on the inner surface of the I-beam, and the reinforcing ribs are not less than eight. Two reinforcing ribs arranged in upper and lower positions are set as a group, and several groups of reinforcing ribs are arranged in a rectangular and equidistant manner on the inner surface of the I-beam. A coupling support assembly is provided on the inner surface of the I-beam, and the coupling support assembly comprises a plurality of connecting round seats, and the plurality of connecting round seats are rotatably connected to the inner surface of the I-beam, and every two of the connecting round seats are set as a group, and each group of the connecting round seats is arranged on both sides of the reinforcing rib, and each of the connecting round seats is rotatably connected to a lifting ring on one side close to the center of the I-beam, and an iron chain is installed between every two of the lifting rings, and an elastic rope is fixedly connected between every two reinforcing ribs arranged in upper and lower positions, and the outer surface of each of the elastic ropes is linearly and equidistantly arranged and fixedly connected to a plurality of coupling columns.

[0014] Preferably, the outer surface of each of the elastic ropes is linearly and equidistantly arranged and fixedly connected with a plurality of embedded beads, and each of the coupling columns is provided with coupling grooves on both upper and lower sides.

[0015] Preferably, the embedded beads are configured to have a shape in which the upper and lower sides shrink synchronously, and the shape of the coupling groove matches the shape of the embedded beads.

[0016] Preferably, the coupling columns closest to the reinforcing rib are all fixedly connected to the outer surface of the reinforcing rib, and the contact surface thereof is matched with the inclined surface shape of the reinforcing rib.

[0017] Preferably, guide plates are symmetrically mounted on the inner surface of the bottom side of the I-beam.

[0018] Preferably, the guide plate is arranged in a stepped shape, and the surface of the guide plate has wavy protrusions and depressions.

[0019] Preferably, the bottom of the guide plate expands outward, and the bottom of the guide plate wraps around the bottom of the I-beam.

[0020] Preferably, a flange anti-fouling assembly is provided on the top side of the I-beam, and the flange anti-fouling assembly includes a plurality of fan blades, and the plurality of fan blades are installed on the outer surface of the connecting round seat located at the top, and the outer surface of the connecting round seat located at the top is installed with a detection module, and the inner surface of the top side of the I-beam is symmetrically provided with U-shaped grooves.

[0021] Preferably, the fan blades are arranged in a spiral shape and are equidistantly arranged on the outer surface of the connecting circular seat, and the inner surface of the top side of the I-beam is arranged in a rectangular shape and is equidistantly provided with flow channels, and each of the flow channels has a plurality of slot blocks arranged linearly and equidistantly and fixedly connected thereto.

[0022] Preferably, the flow passages are all arranged in a T-shape, and the slot blocks inside the flow passages are all staggeredly arranged in two rows.

[0023] Preferably, both ends of the iron chain are of snap-on design, and the connection between the iron chain and the hanging ring can be released by snapping.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the rotatable iron chain, the hanging ring, the elastic rope and the embedded beads, a certain shaking can be generated when the wind blows, thereby generating changes in the airflow and preventing excessive attachment of water vapor molecules to the I-beam, thereby reducing the possibility of chloride ions in seawater attaching to the I-beam with water vapor. At the same time, as the I-beam continues to bear the load and bend, the elastic rope relaxes, and the embedded beads and the coupling column are embedded with each other, thereby providing additional supporting force. This additional supporting force can provide auxiliary support in time when the I-beam is deformed, thereby enhancing the anti-deformation ability of the steel structure and preventing the deformation from further expanding.

[0025] Among them: the two reinforcing ribs are distributed in opposite and symmetrical directions to balance the reinforcement effect, so that the I-beam can be evenly stressed. This design can specifically increase the ability of the flange to resist stress, effectively resist the deformation trend of each flange, prevent local deformation caused by uneven stress, and improve the overall stability and bearing capacity of the steel structure.

[0026] Among them: Since the two reinforcing ribs are not connected as a whole, the space for the I-beam to deform is released. When the steel structure is subjected to external force, the I-beam can deform reasonably within a certain range, avoiding the stimulation of internal stress due to limited deformation, and preventing local yield and plastic deformation.

[0027] Among them: the symmetrical arrangement of small-sized reinforcing ribs not only ensures the reinforcement effect, but also saves materials and space. Compared with the traditional large-scale reinforcement structure, this design reduces the use of materials and reduces costs while meeting the strength and stability requirements of the steel structure. It is also easy to operate during the welding process, making the assembly process of the steel structure more convenient and efficient.

[0028] Among them: in the initial state, the iron chain is in a relaxed state, but when the I-beam is subjected to lateral force, the iron chain is tightened, which can prevent it from lateral bending and twisting to a certain extent, that is, it provides a certain lateral constraint. The lateral constraint can enhance the stability of the steel structure when it is subjected to lateral force and avoid affecting the overall performance of the structure due to excessive lateral deformation.

[0029] Among them: when rain falls on the surface of the I-beam, the iron chain can guide the rain to flow down along its surface, accelerate the discharge of rainwater, prevent rainwater from accumulating on the surface of the steel structure, and reduce the erosion of rainwater on the steel structure.

[0030] Among them: when the steel structure is subjected to external force, the wavy guide plate can disperse the stress and avoid stress concentration in a certain part, thereby improving the fatigue resistance of the steel structure. At the same time, the stepped design is conducive to the rapid discharge of rainwater. Rainwater can flow down the stepped structure on the surface of the guide plate quickly, achieving efficient drainage, reducing the accumulation of rainwater at the bottom of the steel structure, and reducing the risk of corrosion.

[0031] Among them: the bottom of the guide plate expands outward, and the bottom wraps around the bottom of the I-beam, which can effectively prevent rainwater from flowing back. When encountering severe weather such as strong winds or heavy rains, this design can block rainwater from entering the steel structure from the bottom, protecting the internal structure of the steel structure from rainwater erosion. At the same time, the outward-expanding bottom can also increase the contact area between the steel structure and the ground or other supporting structures, thereby improving the stability of the structure.

[0032] Among them: Since the iron chain is a snap-on design, it is easy to replace. During long-term use, if the iron chain is damaged or aged, you only need to simply unfasten the buckle to easily replace it with a new one. There is no need for large-scale disassembly and repair of the entire steel structure, which greatly reduces maintenance costs and repair difficulty.

[0033] Among them: the embedded beads are set to a shape in which the upper and lower sides shrink synchronously. This shape makes the embedding between the embedded beads and the coupling columns tighter and more stable, can better transmit the supporting force, and improves the overall stability and bearing capacity of the steel structure.

[0034] Among them: when the iron chains and elastic ropes are blown by the wind, they can absorb and dissipate part of the energy and play a certain buffering role, reducing the impact of dynamic loads on the steel structure in complex environments and improving the stability of the structure.

[0035] Among them: the iron chain will shake when absorbing wind and vibration forces, but because the lifting ring, connecting round seat and the iron chain are in a rotational relationship, when the iron chain shakes, the lifting ring and the connecting round seat can adapt to the shaking by their own slight rotation, thereby effectively reducing the degree of shaking transmitted to the I-beam.

[0036] 2. When the wind blows, the fan blades are affected by the wind and drive the connecting round seat to rotate. At this time, the air is subjected to additional force and can act more fully on the upper flange of the I-beam. The full action of the air can effectively destroy the low-speed vortex area that may have been formed on the upper flange of the I-beam, reduce the settlement and accumulation of dust and impurities in this area, and also reduce the possibility of dust and impurities in the airflow adhering to the surface of the upper flange, thereby effectively reducing the adhesion of dirt, reducing the risk of erosion of the I-beam by corrosive substances in a humid environment, and protecting the strength and durability of the I-beam.

[0037] Among them: when the fan blades rotate, they drive the connecting round seat to rotate synchronously, thereby enhancing the rotation efficiency of the connecting round seat. The improvement of the rotation efficiency of the connecting round seat enables it to more effectively consume external force and reduce the energy generated during the shaking of the chain. In this way, the shaking energy transmitted to the I-beam will be reduced, thereby reducing the risk of fatigue damage to the I-beam due to shaking.

[0038] Among them: when the fan blades rotate, they will drive the detection module connected to the surface of the round seat to rotate synchronously. Therefore, the detection module can determine the wind force at this time by detecting the rotation speed. When the wind force exceeds a certain threshold, it can issue a warning signal in time to remind relevant personnel to take corresponding protective measures, thus having a certain warning function.

[0039] Among them: when the I-beam bends, the position and posture of the connecting round seat will change. The detection module can accurately detect the bending degree of the I-beam by detecting this change. Once it is detected that the bending degree exceeds the safe range, it can promptly remind the operator to conduct inspection and maintenance to avoid further deterioration of the bending problem.

[0040] Among them: the existence of the U-shaped groove allows wind and dirt to move along the trajectory of the U-shaped groove to the bend of the U-shaped groove. At the bend, the air on both sides will mix and impact, forming a strong airflow disturbance. This airflow disturbance can make it easier for dirt to fall off the upper flange of the I-beam and fall to the lower flange of the I-beam. At the lower flange, the dirt is more easily discharged with the airflow or rainwater, thereby further reducing the accumulation of dirt on the I-beam.

[0041] Among them: during the rotation of the fan blades, part of the air will enter the flow channel. Since the flow channel is T-shaped and its entrance is relatively narrow, when the air enters, it will be constrained by the shape of the channel and undergo an acceleration process. At the end of the flow channel, the space suddenly becomes larger, and the accelerated air will diffuse in all directions. This air acceleration and diffusion effect can enhance the airflow disturbance around the I-beam, further reduce the adhesion of dust and impurities on the surface of the I-beam, and also help improve the heat dissipation efficiency of the I-beam.

[0042] Among them: when the air flows through the slot block, it will be guided and squeezed by the slot block, so that the air flow rate is further increased. This higher air flow rate can more effectively remove dirt on the surface of the I-beam, and at the same time enhance the heat dissipation effect of the I-beam, which helps to maintain the I-beam working within a suitable temperature range and improve its mechanical properties and durability.

[0043] Among them: since the slot blocks are arranged in a staggered manner, when dust and dirt move from the tail end of the flow channel toward the side close to the fan blades, they will be continuously blocked and hindered by the slot blocks, thereby continuously slowing down the movement speed of the dust and dirt. This deceleration effect can effectively prevent dust and dirt from flowing back to the key parts of the I-beam, protect the surface cleanliness of the I-beam, and reduce the risk of corrosion of the I-beam by dirt.

[0044] Among them: At the same time, the setting of the flow channel and the U-shaped groove increases the surface area of ​​the I-beam, thereby providing a larger heat dissipation area, which helps the I-beam to maintain good thermal stability in a complex environment and improve its overall performance.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] It should be noted that the detection module 32 only provides the function of detecting the angle change of the I-beam 11, and the working principle and specific structure of the detection module 32 are both existing technologies. Therefore, in view of the versatility of the detection module 32, its specific principle will not be repeated later.

[0060] Example 1, please refer to Figures 1 to 5 As shown, a novel high-strength and corrosion-resistant steel structure includes an I-beam 11, and a plurality of reinforcing ribs 12 are installed on the inner surface of the I-beam 11. The reinforcing ribs 12 are not less than eight, and two reinforcing ribs 12 arranged in upper and lower positions are set as a group. The plurality of groups of reinforcing ribs 12 are arranged in a rectangular and equidistant manner on the inner surface of the I-beam 11. A coupling support assembly 2 is provided on the inner surface of the I-beam 11. The coupling support assembly 2 includes a plurality of connecting round seats 21, and the plurality of connecting round seats 21 are rotatably connected to the inner surface of the I-beam 11, and every two connecting round seats 21 are set as a group. Each group of connecting round seats 21 is arranged on both sides of the reinforcing rib 12, and a lifting ring 22 is rotatably connected to one side of each connecting round seat 21 close to the center of the I-beam 11, and an iron chain 23 is installed between every two lifting rings 22, and an elastic rope 24 is fixedly connected between every two reinforcing ribs 12 arranged in upper and lower positions, and the outer surface of each elastic rope 24 is linearly and equidistantly arranged and fixedly connected to a plurality of coupling columns 26.

[0061] Please refer to Figures 5 to 7 As shown, the outer surface of each elastic rope 24 is linearly and equidistantly arranged and fixedly connected with a plurality of embedded beads 25, the upper and lower sides of each coupling column 26 are provided with coupling grooves 27, and the bottom inner surface of the I-beam 11 is symmetrically installed with guide plates 28.

[0062] It should be noted that the guide plate 28 is arranged in a stepped shape, and the surface of the guide plate 28 has wavy protrusions and depressions, the embedded beads 25 are arranged in a shape that shrinks synchronously on the upper and lower sides, the shape of the coupling groove 27 is adapted to the shape of the embedded beads 25, the coupling columns 26 closest to the reinforcing rib 12 are fixedly connected to the outer surface of the reinforcing rib 12, and their contact surfaces are adapted to the inclined shapes of the reinforcing rib 12, the bottom of the guide plate 28 expands outward, and the bottom of the guide plate 28 wraps the bottom of the I-beam 11.

[0063] Specifically, when the I-beams 11 are installed together, they form a transverse support beam, which undertakes the core tasks of bearing and supporting in the steel structure system.

[0064] Among them, when the steel structure is subjected to vertical loads: during use, the I-beam 11, as an important load-bearing component, will be subjected to the effects of a variety of complex forces. In the vertical direction, the vertical load transmitted from above (such as the deadweight of the building, the weight of personnel and equipment, etc.) acts on the upper surface of the I-beam 11. The upper flange first bears the force, and then through the continuous action of the web, the force is evenly transmitted to the lower flange, so that the upper and lower flanges are subjected to force synchronously.

[0065] Under the action of vertical load, the upper and lower flanges are loaded like simply supported beams, and will have a tendency to bend and deform. According to the theory of material mechanics, when the flange bends, the side away from the neutral axis is subjected to tensile stress, and the side close to the neutral axis is subjected to compressive stress. This stress distribution causes the flange to have a deformation tendency to expand outward or contract inward.

[0066] Since the reinforcing ribs 12 are oppositely and symmetrically distributed on the inner surface of the I-beam 11, when a vertical load is applied to the I-beam 11, the reinforcing ribs 12 closely connected to the flange can change the stress state of the flange. It shares part of the stress of the flange and disperses the stress originally concentrated on the local part of the flange to a larger area. Specifically, after the bending stress generated by the flange under the vertical load is transmitted to the reinforcing ribs 12, the reinforcing ribs 12 diffuse the stress to the surrounding area with their own structural stiffness, making the stress distribution of the flange more uniform, while providing additional support for the flange, effectively suppressing flange deformation.

[0067] Among them, when the steel structure is subjected to lateral loads: In actual projects, the I-beam 11 will be subjected to lateral loads. Wind in the natural environment is a common source of lateral loads. When strong wind acts on the steel structure as a whole, it will be transmitted to the I-beam 11 to form lateral force. In addition, the vibration and impact force generated by the operation of vehicles will also cause the I-beam 11 to be subjected to lateral loads.

[0068] The lateral force will cause the I-beam 11 to bend to one side as a whole, and the lower flange is more easily deformed than the upper flange. This is because the lower flange, under the action of the lateral force, not only has to bear its own bending stress, but is also affected by the lateral force transmitted by the web. From the mechanical model, the I-beam 11 can be regarded as a cantilever beam structure with one end fixed and the other end subjected to lateral force. The lower flange is located on the outside of the cantilever beam and is subjected to a greater bending moment. When the lateral force acts, the fixed end of the I-beam 11 provides a restraining reaction force to resist rotation and displacement, and the free end produces bending deformation. Because the lower flange is far away from the fixed end and on the outside of the cantilever beam, according to the law of bending moment distribution, the bending moment value and bending stress here are the largest, so it is more likely to undergo obvious deformation.

[0069] In the initial state, the iron chain 23 is in a relaxed state. When the I-beam 11 is bent due to the lateral force, the iron chain 23 is tightened, and a reverse force is applied to the I-beam 11 through the lifting ring 22 and the connecting round seat 21. After the iron chain 23 is tightened, the tension is transmitted to the side of the I-beam 11 through the lifting ring 22 and the connecting round seat 21, offsetting part of the bending moment caused by the lateral force on the lower flange, reducing the deformation of the lower flange, preventing it from excessive bending, and ensuring the stability of the steel structure under vertical and lateral loads.

[0070] Among them, when the steel structure bends: under the combined action of complex loads, the flange of the I-beam 11 will continue to bend and deform, and the lower flange is constrained by the iron chain 23 and its deformation is limited; while the upper flange lacks similar direct constraints and is easily deformed under continuous load.

[0071] When the upper flange is deformed and bent, the connected elastic rope 24 will relax due to the deformation of the upper flange, and the coupling column 26 on the surface of the elastic rope 24 will tilt accordingly. As the upper flange continues to bend and the elastic rope 24 relaxes, the coupling column 26 continues to conflict with the embedded bead 25, and gradually gets stuck in the embedded bead 25 under the action of force. When this happens at multiple positions at the same time, several coupling columns 26 are connected through the embedded bead 25 to form a conflict-type coupling connection, and they act closely together to form an organic whole.

[0072] At this time, the plurality of coupling columns 26 can be regarded as a whole, which is just stuck between the reinforcing ribs 12. Since the coupling columns 26 are in conflict with each other and are tightly connected to the embedded beads 25, the whole has a certain structural stability and bearing capacity, and can provide lateral force support for the I-beam 11 to prevent further bending. When the I-beam 11 has a tendency to continue bending, the whole will exert a reverse lateral force to offset part of the external force, limit the bending deformation of the I-beam 11, and enhance the stability and bearing capacity of the steel structure.

[0073] Among them, when the steel structure faces a highly humid environment: in a rainy environment, when rain falls on the surface of the I-beam 11, the iron chain 23 can guide the rain to flow down along its surface, accelerate the discharge, and prevent rainwater accumulation. The wavy and stepped guide plate 28 further improves the drainage efficiency. The rainwater flows rapidly along the stepped structure, and the wavy protrusions and depressions cause the rainwater to form turbulence, which speeds up the discharge. At the same time, the bottom of the guide plate 28 expands outward and wraps the bottom of the I-beam 11, which can also prevent rainwater from flowing back and protect the bottom of the steel structure.

[0074] In a humid environment with a certain amount of wind, the wind causes the iron chain 23 to shake. Since the ring 22, the connecting round seat 21 and the iron chain 23 are in a rotational relationship, they can adapt to the shaking through slight rotation, reduce the impact of the shaking on the I-beam 11, and reduce additional stress. At the same time, the iron chain 23 and the elastic rope 24 absorb and dissipate energy when the wind blows, play a buffering role, and reduce the impact of dynamic loads on the steel structure. In addition, the wind causes the iron chain 23, the ring 22, the elastic rope 24 and the embedded beads 25 to shake, causing airflow changes, destroying the attachment conditions of water vapor molecules, reducing the attachment of chloride ions in seawater, and reducing the risk of corrosion.

[0075] Example 2, based on Example 1, please refer to Figure 6 and Figures 8 to 10 As shown, a flange anti-fouling component 3 is provided on the top side of the I-beam 11, and the flange anti-fouling component 3 includes a plurality of blades 31, and the plurality of blades 31 are installed on the outer surface of the connecting round seat 21 located at the top, and a detection module 32 is installed on the outer surface of the connecting round seat 21 located at the top. The detection module 32 is specifically implemented as a gyroscope module, and a protective shell can be installed on the outside of the gyroscope module to provide a protection function for the gyroscope module. U-shaped grooves 33 are symmetrically provided on the inner surface of the top side of the I-beam 11, and the blades 31 are spirally arranged and equidistantly arranged on the outer surface of the connecting round seat 21. The inner surface of the top side of the I-beam 11 is rectangularly arranged and equidistantly provided with flow channels 34, and each flow channel 34 has a plurality of slot blocks 35 fixedly connected thereto in a linearly equidistant arrangement.

[0076] It should be noted that the flow passages 34 are all arranged in a T-shape, and the slot blocks 35 inside the flow passages 34 are all arranged in two rows in a staggered manner.

[0077] Specifically, it has been clearly stated in the background art that the air flow characteristics in humid areas result in poor ventilation effect at the upper flange of the I-beam 11 , poor air circulation, and thus more prone to dirt accumulation.

[0078] When wind blows, the fan blades 31 will rotate, and further rotation of the fan blades 31 will generate additional force, which can push the air into the I-beam 11.

[0079] In the process of air being pushed, two main flow paths and cleaning effects will be generated. On the one hand, part of the air will be pushed into the U-shaped groove 33. When this part of the air flows in the U-shaped groove 33, due to the special shape of the U-shaped groove 33, the air will impact, mix and collide at the bend in the middle. In this process, the dust and impurities originally attached to the upper flange surface of the I-beam 11 will be separated from the upper flange surface due to the impact and collision of the air. Due to the structural design of the U-shaped groove 33, dust and impurities will fall to the lower flange under the combined action of gravity and airflow. Since the lower flange has a good ventilation effect, the air can flow more smoothly, and this part of the dust and impurities can be discharged automatically with the airflow, thereby avoiding accumulation at the upper flange.

[0080] On the other hand, part of the air will be pushed to the flow channel 34. Since the flow channel 34 is designed to be T-shaped, when the air enters the flow channel 34, the entrance of the channel is relatively small, and the air will first undergo an acceleration process. As the air flows in the channel and reaches the tail end of the flow channel 34, the air will diffuse here due to the larger area of ​​the tail end. At the same time, the groove block 35 inside the flow channel 34 is not completely connected to the side wall of the channel. During the flow, the air will be continuously diverted by the groove block 35 and then continuously converged. This process of diversion and convergence makes the flow speed of the air constantly change, and the air is constantly accelerated, thereby forming an airflow with a strong impact force. This airflow will eventually clean both sides of the flange of the I-beam 11 and blow away the dust and impurities attached to both sides.

[0081] It should be noted that, since the slot blocks 35 are arranged in an staggered manner, when dust and impurities reflux due to a high speed, this arrangement of the slot blocks 35 can continuously block the dust and impurities. After encountering the obstruction of the slot blocks 35, the dust and impurities will continue to be diverted. In the process of converging, the mainstream and the diverted flow have opposite movement directions, so that the dust and impurities are continuously decelerated. Under the action of gravity, these decelerated dust and impurities will eventually fall to the lower flange of the I-beam 11, further avoiding the accumulation of dirt on the upper flange, ensuring the cleanliness of the upper flange of the I-beam 11, extending its service life, and improving the overall performance of the steel structure.

[0082] In addition, the detection module 32 also plays an important role in the use of the I-beam 11: on the one hand, since the fan blades 31 are installed on the connecting round seat 21, when wind blows, the fan blades 31 will drive the connecting round seat 21 to rotate, and the detection module 32 can detect the wind force by sensing the rotation of the connecting round seat 21.

[0083] Specifically, when the wind force is small, the rotation speed of the fan blades 31 and the connecting round seat 21 is relatively slow, and the rotation angular velocity detected by the gyroscope module is small; when the wind force increases, the rotation speed of the fan blades 31 and the connecting round seat 21 will increase, and the rotation angular velocity detected by the gyroscope module will increase accordingly. Through the precise measurement and analysis of the rotation angular velocity, the detection module 32 can obtain the wind force information in real time, which is of great significance for monitoring the wind conditions in the environment where the I-beam 11 is located. For example, in strong wind weather, relevant personnel can take protective measures in advance according to the wind force to ensure the safety and stability of the steel structure.

[0084] On the other hand, when the I-beam 11 bends under various loads, the position and posture of the connecting round seat 21 will also change accordingly. The gyroscope module can keenly sense this change, thereby detecting the degree of bending of the I-beam 11. When the I-beam 11 is in a normal state, the gyroscope module records the initial posture data. When the I-beam 11 begins to bend, the posture of the connecting round seat 21 will deviate from the initial state. The gyroscope module calculates the degree of bending of the I-beam 11 by comparing the difference between the current posture data and the initial posture data. Once it is detected that the degree of bending of the I-beam 11 exceeds a preset safety threshold, the detection module 32 will immediately generate an early warning signal, which can be transmitted to relevant monitoring systems or management personnel to remind them to inspect and maintain the I-beam 11 in a timely manner to prevent further aggravation of the bending degree, avoid possible safety accidents, and ensure the overall stability and safety of the steel structure.
