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] Second, in humid areas, the flow state of air is comprehensively affected by various factors and usually shows a tendency of parallel flow or downward flow, while the upward flow of air is relatively less. 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 principle of thermal convection that hot air rises and cold air sinks, the warm and humid air tends to rise, and the surrounding relatively cold air will supplement it. In this process, the cold air mostly flows parallel to the ground or downward to fill the space left by the rising warm and humid air, resulting in relatively less upward flow of air.
[0008] When the air flow passes parallel to the I-beam, the shape at the bottom of the upper flange of the I-beam will change suddenly. This sudden change will interfere with the original flow state of the air flow, thereby triggering the boundary layer separation phenomenon. In this process, a low-speed vortex area will be formed. In the vortex area, the air flow speed decreases significantly, and the ability of the air flow to carry dust and impurities is closely related to the air flow speed. After the speed decreases, its carrying ability also weakens accordingly. In this way, the dust and impurities that originally moved with the air flow are likely to settle and accumulate in this vortex area.
[0009] When the air flow flows downward, a certain windward surface will be formed at the upper flange of the I-beam. After the dust and impurities in the air flow 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 the upward air flow is less, it is difficult to effectively carry and remove upward the dust and impurities that have adhered to and accumulated on the upper flange, which makes it easier for the dust and impurities to accumulate on the upper flange.
[0010] And because the 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] Therefore, the present invention proposes a new type of 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 object, the present invention provides the following technical solution: a new type of high-strength and corrosion-resistant steel structure, including an I-beam. A number of reinforcing ribs are installed on the inner surface of the I-beam. The number of the reinforcing ribs is not less than eight, and two reinforcing ribs arranged vertically are set as a group. A number of groups of the reinforcing ribs are arranged at equal intervals in a rectangular shape on the inner surface of the I-beam. A coupling support assembly is arranged on the inner surface of the I-beam. The coupling support assembly includes a number of connecting round seats. A number of the connecting round seats are all rotatably connected to the inner surface of the I-beam, and every two of the connecting round seats are set as a group. Each group of the connecting round seats is arranged on both sides of the reinforcing rib. A suspension ring is rotatably connected to one side of each connecting round seat close to the center of the I-beam. A chain is installed between every two of the suspension rings. An elastic cord is fixedly connected between every two reinforcing ribs arranged vertically. A number of coupling columns are fixedly connected to the outer surface of each elastic cord at equal intervals linearly.
[0014] Preferably, a number of inlaid beads are fixedly connected to the outer surface of each elastic cord at equal intervals linearly. Coupling grooves are opened on both the upper and lower sides of each coupling column.
[0015] Preferably, the inlaid beads are all set in a shape of synchronous contraction on the upper and lower sides, and the shape of the coupling groove is adapted to the shape of the inlaid bead.
[0016] Preferably, the coupling columns closest to the reinforcing ribs are all fixedly connected to the outer surface of the reinforcing rib, and the contact surface thereof is adapted to the inclined surface shape of the reinforcing rib.
[0017] Preferably, guide plates are symmetrically installed on the inner surface of the bottom side of the I-beam.
[0018] Preferably, the guide plates are set in a stepped shape, and the surfaces of the guide plates all have wavy protrusions and depressions.
[0019] Preferably, the bottom of the guide plate expands outward, and the bottom of the guide plate wraps the bottom of the I-beam.
[0020] Preferably, a flange anti-pollution assembly is arranged on the top side of the I-beam. The flange anti-pollution assembly includes a number of fan blades. A number of the fan blades are all installed on the outer surface of the connecting round seat at the top. Detection modules are installed on the outer surface of the connecting round seat at the top. U-shaped grooves are symmetrically opened on the inner surface of the top side of the I-beam.
[0021] Preferably, the fan blades are all arranged at equal intervals in a spiral shape on the outer surface of the connecting round seat. Flow channels are opened on the inner surface of the top side of the I-beam at equal intervals in a rectangular shape. A number of groove blocks are fixedly connected to the inside of each flow channel at equal intervals linearly.
[0022] Preferably, the flow-through channels are all arranged in a T shape, and the groove blocks inside the flow-through channels are misaligned and arranged in two rows.
[0023] Preferably, the two ends of the iron chain are designed in a snap-fastening manner, that is, the connection between the iron chain and the hanging ring can be released through the snap.
[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the rotatable iron chain, hanging ring, elastic rope and inlaid beads, when the wind blows, it can produce a certain shaking, thereby generating a change in air flow, and preventing excessive attachment of water vapor molecules to the I-beam, thus reducing the possibility of chloride ions in seawater attaching to the I-beam along with water vapor. At the same time, when the I-beam continuously bears the load and bends, the elastic rope relaxes, and the inlaid beads and coupling columns are mutually inlaid, thereby providing additional supporting force. This additional supporting force can provide auxiliary support in time when the I-beam deforms, enhance the anti-deformation ability of the steel structure, and prevent the deformation from further expanding.
[0025] Among them: By the reverse and symmetrical distribution of the two stiffeners, the strengthening effect is balanced, enabling the I-beam to 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 load-bearing capacity of the steel structure.
[0026] Among them: Since the two stiffeners are not connected as a whole, the deformable space of the I-beam is released. When the steel structure is subjected to external forces, the I-beam can deform reasonably within a certain range, avoiding the excitation of internal stress due to limited deformation, and preventing local yield and plastic deformation.
[0027] Among them: The small-sized stiffeners are symmetrically arranged, which not only ensures the strengthening effect but also saves materials and space. Compared with the traditional large-scale strengthening structure, this design reduces the material usage and cost while meeting the strength and stability requirements of the steel structure. At the same time, it is 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 a lateral force, the iron chain is tightened, thereby preventing it from undergoing lateral bending and torsion to a certain extent, that is, providing a certain lateral restraint. The lateral restraint can enhance the stability of the steel structure when subjected to lateral forces and avoid affecting the overall performance of the structure due to excessive lateral deformation.
[0029] Among them: When rainwater falls on the surface of the I-beam, the iron chain can guide the rainwater to flow down along its surface, accelerating the discharge of rainwater, preventing rainwater from accumulating on the surface of the steel structure, and reducing the erosion of rainwater on the steel structure.
[0030] Among them: when the steel structure is subjected to external forces, the wavy guide plate can disperse stress, 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. The rainwater can quickly flow down along the stepped structure on the surface of the guide plate, achieving efficient drainage, reducing the accumulation of rainwater at the bottom of the steel structure, and reducing the corrosion risk.
[0031] Among them: the bottom of the guide plate expands outward and wraps the bottom of the I-beam, which can effectively prevent rainwater from flowing back. When encountering bad weather such as strong winds or heavy rains, this design can block rainwater from entering the interior of the steel structure from the bottom, protecting the internal structure of the steel structure from rain 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, improving the stability of the structure.
[0032] Among them: since the iron chain is of a snap-fastener design, it is also convenient to replace. During long-term use, if the iron chain is damaged or aged, etc., simply unfasten the snap, and a new iron chain can be easily replaced without large-scale disassembly and repair of the entire steel structure, greatly reducing the maintenance cost and repair difficulty.
[0033] Among them: the inlaid beads are set in a shape that contracts synchronously on the upper and lower sides. This shape makes the inlay between the inlaid beads and the coupling columns tighter and more stable, can better transmit the supporting force, and improves the overall stability and load-bearing capacity of the steel structure.
[0034] Among them: during the process of the iron chain and the elastic rope being blown by the wind, they can absorb and dissipate part of the energy and play a certain buffering role, reducing the influence of the dynamic load borne by the steel structure in a complex environment and improving the stability of the structure.
[0035] Among them: when the iron chain absorbs wind force and vibration force, it will shake. However, since there is a rotational relationship between the hanging ring, the connecting round seat and the iron chain, when the iron chain shakes, the hanging ring and the connecting round seat can adapt to this shake through their own small rotations, thereby effectively reducing the degree of shake transmitted to the I-beam.
[0036] 2. When blown by the wind, the fan blades are affected by the wind force and drive the connecting round seat to rotate. At this time, the air is subjected to an additional force and can act more fully on the upper flange of the I-beam. This full action of the air can effectively destroy the low-speed vortex area that may originally form on the upper flange of the I-beam, reduce the settlement and accumulation of dust and impurities in this area, and at the same time can also weaken the possibility of dust and impurities in the air flow adhering to the surface of the upper flange, thereby effectively reducing the adhesion of dirt and reducing the erosion risk of corrosive substances to the I-beam in a humid environment, protecting the strength and durability of the I-beam.
[0037] Wherein: When the fan blade rotates, it drives the connecting circular seat to rotate synchronously, thereby enhancing the rotation efficiency of the connecting circular seat. The improvement of the rotation efficiency of the connecting circular seat enables it to more effectively consume external forces and reduce the energy generated during the swaying of the iron chain. In this way, the swaying energy transmitted to the I-beam will be reduced, thereby reducing the risk of fatigue damage to the I-beam caused by swaying.
[0038] Wherein: When the fan blade rotates, it drives the detection module on the surface of the connecting circular seat to rotate synchronously. Therefore, the detection module can judge 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 a timely manner to remind relevant personnel to take corresponding protective measures, thus having a certain warning function.
[0039] Wherein: When the I-beam bends, the position and posture of the connecting circular seat will change. The detection module can accurately detect the bending degree of the I-beam by detecting this change. Once it detects that the bending degree exceeds the safe range, it can promptly remind the operator to conduct inspections and maintenance to avoid the further deterioration of the bending problem.
[0040] Wherein: The existence of the U-shaped groove enables 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 to form a strong air flow disturbance. This air flow disturbance can make the dirt more easily fall off from the upper flange of the I-beam and drop to the lower flange of the I-beam. At the lower flange, the dirt is more easily discharged with the air flow or rainwater, etc., thereby further reducing the accumulation of dirt on the I-beam.
[0041] Wherein: During the rotation of the fan blade, part of the air will enter the internal flow channel. Since the flow channel is T-shaped and its inlet is relatively narrow, when the air enters, it will be restricted by the channel shape and experience an acceleration process. At the end of the flow channel, the space suddenly becomes larger, and the accelerated air will diffuse towards the surroundings. This acceleration and diffusion effect of the air can enhance the air flow disturbance around the I-beam, further reducing the adhesion of dust and impurities on the surface of the I-beam, and also contributing to improving the heat dissipation efficiency of the I-beam.
[0042] Wherein: When the air flows through the groove block, it will be guided and squeezed by the groove block, thereby further increasing the air flow velocity. This higher air flow velocity can more effectively remove the dirt on the surface of the I-beam, and also enhances the heat dissipation effect of the I-beam, helping to maintain the I-beam working within a suitable temperature range and improving its mechanical properties and durability.
[0043] Among them: Since the groove blocks are arranged in a staggered manner, when dust and dirt move from the tail end of the flow-through channel towards the side close to the fan blade, they will continuously be blocked and hindered by the groove blocks, thereby continuously reducing the movement speed of the dust and dirt. This deceleration effect can effectively prevent the dust and dirt from flowing back to the key parts of the I-beam, protecting the surface cleanliness of the I-beam and reducing the corrosion risk of the dirt to the I-beam.
[0044] Among them: At the same time, the setting of the flow-through 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 maintain good thermal stability in a complex environment and improve its overall performance.

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope 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 prior arts. Therefore, due to the generality of the detection module 32, its specific principle will not be described in detail hereinafter.
[0060] Example 1, please refer to Figures 1 to 5 As shown, a new type of high-strength and corrosion-resistant steel structure includes an I-beam 11. A plurality of reinforcing ribs 12 are installed on the inner surface of the I-beam 11. There are no less than eight reinforcing ribs 12, and two reinforcing ribs 12 arranged in the upper and lower positions are set as a group. A 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 arranged on the inner surface of the I-beam 11. The coupling support assembly 2 includes a plurality of connecting circular seats 21. A plurality of connecting circular seats 21 are all rotatably connected to the inner surface of the I-beam 11, and every two connecting circular seats 21 are set as a group. Each group of connecting circular seats 21 is arranged on both sides of the reinforcing rib 12. A suspension ring 22 is rotatably connected to the side of each connecting circular seat 21 close to the center of the I-beam 11. An iron chain 23 is installed between every two suspension rings 22. An elastic cord 24 is fixedly connected between every two reinforcing ribs 12 arranged in the upper and lower positions. A plurality of coupling columns 26 are fixedly connected to the outer surface of each elastic cord 24 in a linearly equidistant manner.
[0061] Please refer to Figures 5 to 7 As shown, a plurality of embedded beads 25 are fixedly connected to the outer surface of each elastic cord 24 in a linearly equidistant manner. Coupling grooves 27 are opened on both the upper and lower sides of each coupling column 26. Guide plates 28 are symmetrically installed on the inner surface of the bottom side of the I-beam 11.
[0062] It should be noted that the guiding plate 28 is arranged in a stepped shape, and the surface of the guiding plate 28 has wavy protrusions and depressions. The inlaid beads 25 are all arranged in a shape with synchronous contraction on the upper and lower sides. The shape of the coupling groove 27 is adapted to the shape of the inlaid bead 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 surface shape of the reinforcing rib 12. The bottom of the guiding plate 28 expands outward, and the bottom of the guiding plate 28 wraps the bottom of the I-beam 11.
[0063] Specifically, when the I-beams 11 are installed with each other, they form a transverse support beam, undertaking the core tasks of load-bearing and support in the steel structure system.
[0064] Among them, when the steel structure bears vertical loads: During use, as an important load-bearing component, the I-beam 11 will be subjected to various complex forces. In the vertical direction, the vertical loads transmitted from above (such as the self-weight of the building, the weight of personnel and equipment, etc.) act on the upper surface of the I-beam 11. The upper flange first bears this force, and then through the continuous action of the web, the force is evenly transmitted to the lower flange, enabling the upper and lower flanges to be stressed synchronously.
[0065] Under the action of vertical loads, the upper and lower flanges are similar to simply supported beams under load and will have a tendency to bend and deform. According to the theory of mechanics of materials, when the flange bends, the side far 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 tendency to expand outward or contract inward.
[0066] Since the reinforcing ribs 12 are distributed symmetrically and in the opposite direction 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 in the local area of the flange to a larger area. Specifically, after the bending stress generated by the lower flange under the vertical load is transmitted to the reinforcing rib 12, the reinforcing rib 12 diffuses the stress around it by virtue of its own structural stiffness, making the stress distribution of the flange more uniform, and at the same time providing an additional support force for the flange, effectively suppressing the deformation of the flange.
[0067] Among them, when the steel structure bears lateral loads: In actual engineering, the I-beam 11 will bear lateral loads. Wind force in the natural environment is a common source of lateral loads. When strong wind acts on the overall steel structure, it will be transmitted to the I-beam 11 to form a lateral force. In addition, the vibration and impact force generated by the operation of transportation tools will also cause the I-beam 11 to bear 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] During the process of air being pushed, two main flow paths and cleaning effects are generated. On the one hand, part of the air is 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 undergo impact mixing and collision at the bending part in the middle. During this process, the dust and impurities originally attached to the upper flange surface of the I-beam 11 will be detached 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, under the combined action of gravity and air flow, the dust and impurities will fall to the lower flange. Since the lower flange has good ventilation and the air can flow relatively smoothly, this part of the dust and impurities can be discharged by itself along with the air flow, thus avoiding accumulation on the upper flange.
[0080] On the other hand, part of the air is pushed to the flow-through channel 34. Since the flow-through channel 34 is designed in a T shape, when the air enters the flow-through channel 34, the entrance of the channel is relatively small, and the air will first experience an acceleration process. As the air flows in the channel and reaches the end of the flow-through channel 34, due to the larger area at the end, the air will diffuse here. At the same time, the groove block 35 inside the flow-through channel 34 is not completely connected to the side wall of the channel. During the air flow, the air will be continuously shunted by the groove block 35 and then continuously confluent. This process of shunting and confluence makes the flow velocity of the air constantly change, and the air is continuously accelerated, thus forming an air flow with strong impact force. This air flow will finally clean the two sides of the upper flange of the I-beam 11 and blow away the dust and impurities attached to the two sides.
[0081] It should be noted that since the groove blocks 35 are arranged in a staggered manner, when the dust and impurities generate a backflow situation due to a relatively large speed, this arrangement of the groove blocks 35 can continuously block the dust and impurities. After the dust and impurities encounter the blockage of the groove blocks 35, they will be continuously shunted. During the confluence process, the main flow and the shunted flow generate opposite movement directions, so that the dust and impurities are continuously decelerated. Under the action of gravity, these decelerated dust and impurities will finally 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 during the use of the I-beam 11: on the one hand, since the fan blade 31 is installed on the connecting circular seat 21, when the wind blows, the fan blade 31 will drive the connecting circular seat 21 to rotate, and the detection module 32 can detect the wind force by sensing the rotation of the connecting circular seat 21.
[0083] Specifically, when the wind force is small, the rotation speeds of the fan blades 31 and the connecting circular base 21 are relatively slow, and the rotational angular velocity detected by the gyroscope module is small; while when the wind force increases, the rotation speeds of the fan blades 31 and the connecting circular base 21 will increase, and the rotational angular velocity detected by the gyroscope module will increase accordingly. By precisely measuring and analyzing the rotational angular velocity, the detection module 32 can obtain the magnitude information of the wind force in real time, which is of great significance for monitoring the wind force condition of 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 magnitude 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 attitude of the connecting circular base 21 will also change accordingly. The gyroscope module can keenly sense this change, thereby detecting the bending degree of the I-beam 11. In the normal state of the I-beam 11, the gyroscope module records the initial attitude data. When the I-beam 11 starts to bend, the attitude of the connecting circular base 21 will deviate from the initial state. The gyroscope module calculates the bending degree of the I-beam 11 by comparing the difference between the current attitude data and the initial attitude data. Once it detects that the bending degree of the I-beam 11 exceeds the preset safety threshold, the detection module 32 will immediately generate a warning signal, which can be transmitted to the relevant monitoring system or management personnel to remind them to check and maintain the I-beam 11 in time, prevent the bending degree from further intensifying, avoid possible safety accidents, and ensure the overall stability and safety of the steel structure.
