Description

Technical Field

[0001] This application relates to the field of building materials technology, and in particular to a corrosion-resistant reinforced steel profile. Background Technology

[0002] In the field of construction engineering, structural steel is widely used as an important structural material. To extend the service life of structural steel, a common practice is to electroplate a layer of zinc onto its surface to enhance its corrosion resistance. However, during actual transportation, improper handling by personnel, such as rough loading and unloading, collisions, and the shaking of transport vehicles, can easily damage the anti-corrosion layer on the surface of the structural steel. Once the anti-corrosion layer on the surface of the structural steel is damaged, it is highly susceptible to rust when used in humid, acidic, or alkaline environments.

[0003] Corrosion poses a significant threat to structural steel. On one hand, it gradually erodes the surface of the steel, reducing its cross-sectional dimensions and consequently its load-bearing capacity, thus affecting the stability of the entire building structure. On the other hand, corrosion further weakens the connection strength between steel sections. Especially under long-term vibration and impact loads, bolts and other connectors at steel joints are prone to loosening and falling off due to corrosion. This greatly increases the safety hazards of the building structure and, in severe cases, may even lead to accidents, threatening people's lives and property. Utility Model Content

[0004] To enhance the connection strength and corrosion resistance of steel profiles, this application provides a corrosion-resistant reinforced steel profile.

[0005] The corrosion-resistant reinforced steel section provided in this application adopts the following technical solution:

[0006] A corrosion-resistant reinforced steel profile includes a steel body with a composite anti-corrosion layer on its surface. The steel body has several connecting holes, each containing a reinforcing sleeve. On opposite sides of the steel body's length-direction side walls, grooves are recessed, with the ends of the grooves extending to the end walls of the steel body. A door-shaped anti-collision sleeve is slidably fitted onto the steel body, with a slider located within and slidingly engaging with the groove at its end.

[0007] By adopting the above technical solutions, the composite anti-corrosion layer applied to the surface of the steel profile significantly improves its overall corrosion resistance, effectively resisting erosion from humid, acidic, and alkaline environments, thereby extending its service life. Simultaneously, the reinforcing sleeves embedded in the connecting holes enhance the structural strength of the steel profile's connection points, reducing the problem of decreased connection strength due to corrosion. Furthermore, the cooperation between the sliding groove and the sliding block allows the steel profile to be protected from external impact damage during transportation by using anti-collision sleeves. The position of the anti-collision sleeves can also be easily adjusted according to actual needs, improving the safety and reliability of the steel profile during transportation and use.

[0008] Optionally, the anti-collision sleeve includes a protective plate that fits the outer surface of the steel body, a pressure-resistant plate sleeved on the outside of the protective plate, and a reinforcing rib plate connecting the pressure-resistant plate. Several reinforcing rib plates are distributed between the protective plate and the pressure-resistant plate. The reinforcing rib plates are triangular in shape, with the apex of the reinforcing rib plate set on the pressure-resistant plate, and the hypotenuse corresponding to the apex of the reinforcing rib plate fitting on the protective plate.

[0009] By adopting the above technical solution, the external impact sleeve of the steel profile can effectively absorb and disperse external impact forces. The protective plate fits tightly against the outer surface of the steel profile, providing basic protection; the pressure-resistant plate further enhances the overall strength of the impact sleeve, resisting external pressure; and several triangularly arranged reinforcing ribs, through their unique structural design, evenly distribute the impact force throughout the entire impact sleeve, reducing the possibility of surface damage to the steel profile due to excessive localized stress. This significantly improves the impact resistance of the steel profile during transportation and use, reduces the risk of corrosion layer damage caused by external collisions, and thus extends the service life of the steel profile.

[0010] Optionally, the slider is hemispherical.

[0011] By adopting the above technical solution, the hemispherical shape of the slider effectively reduces the frictional resistance between the slider and the groove, making the anti-collision sleeve slide more smoothly on the steel body. At the same time, the hemispherical design also improves the stability of the slider in the groove, reducing the risk of the slider getting stuck or falling out of the groove due to external impact, thereby improving the protective effect of the anti-collision sleeve on the steel body.

[0012] Optionally, the composite anti-corrosion layer includes a primer layer, an intermediate paint layer, and a topcoat layer stacked sequentially. The primer layer is applied to the surface of the steel body, the intermediate paint layer covers the surface of the primer layer, and the topcoat layer covers the surface of the intermediate paint layer.

[0013] By adopting the above technical solutions, the multi-layered anti-corrosion layer can form a more comprehensive protective barrier, exhibiting a more stable protective effect, especially under complex working conditions. The primer layer, as the base coating, effectively improves the adhesion between the steel surface and subsequent coatings, while initially blocking the intrusion of external corrosive substances. The intermediate paint layer further enhances anti-corrosion performance, fills any possible micropores, and improves the overall density of the coating. The topcoat layer, as the outermost protective layer, has excellent weather resistance and corrosion resistance, and can resist the erosion of moisture, oxygen, and other corrosive media in the external environment.

[0014] Optionally, the primer layer is made of zinc-rich material, the intermediate paint layer is made of epoxy micaceous iron oxide material, and the topcoat layer is made of fluorocarbon material.

[0015] By adopting the above technical solution, the composite anti-corrosion layer consists of a zinc-rich primer layer, an epoxy micaceous iron oxide intermediate paint layer, and a fluorocarbon topcoat layer. The selection of each coating material fully utilizes its respective protective performance. The zinc-rich primer layer has excellent cathodic protection, effectively slowing down the corrosion process of the steel substrate; the epoxy micaceous iron oxide intermediate paint layer provides good shielding effect and adhesion, further enhancing anti-corrosion performance; the fluorocarbon topcoat layer has excellent weather resistance and chemical stability, resisting the erosion of the steel surface by external environmental factors. The combination of these three layers significantly improves the overall corrosion resistance of the steel section and extends its service life.

[0016] Optionally, the outer wall of the reinforcing sleeve is tightly fitted to the wall of the connecting hole, and the inner wall of the reinforcing sleeve has a threaded structure that mates with the bolt thread.

[0017] By adopting the above technical solution, the reinforcing sleeve fits tightly against the wall of the connecting hole, effectively improving the sealing of the connection and preventing moisture and corrosive substances from penetrating into the steel profile, thereby enhancing the corrosion resistance of the steel profile. Simultaneously, the threaded structure on the inner wall of the reinforcing sleeve, which mates with the bolt threads, not only improves the stability of the bolted connection but also further enhances the anti-loosening ability of the steel profile connection by increasing the contact area and friction, ensuring that the steel profile maintains good connection strength during long-term use.

[0018] Optionally, the outer diameter of the reinforcing sleeve is larger than the diameter of the connecting hole, and it is fitted onto the connecting hole.

[0019] By adopting the above technical solution, the outer diameter of the reinforcing sleeve is larger than the diameter of the connecting hole and is fitted onto the connecting hole, which effectively increases the contact area between the reinforcing sleeve and the steel body, thereby improving the structural strength of the connecting hole area. This reduces the possibility of damage to the steel material around the connecting hole due to external forces during use, further enhancing the overall durability and safety of the steel structure.

[0020] Optionally, an installation groove is provided on the contact surface of the connection part of the steel body, and a sealing strip is inserted into the installation groove. The sealing strip has an I-shaped cross section, and the protruding parts on both sides of the sealing strip are embedded in the installation groove. The middle part of the sealing strip extends to the contact surface of the steel body, and the protruding parts on both sides of the sealing strip extend out of the steel body and cover the contact surface of the steel body.

[0021] By adopting the above technical solution, the I-shaped sealing strip can effectively fill the gaps at the connection points of the steel profile. Its two protruding sides are embedded in the mounting groove, improving the stability of the connection. Simultaneously, the middle section extends to the contact surface and covers both sides, creating a multi-layered sealing effect. This design not only improves the waterproof performance of the steel profile connection but also significantly reduces the risk of external corrosive substances penetrating into the connection area, thereby enhancing the overall durability and structural stability of the steel profile.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The composite anti-corrosion layer applied to the surface of the steel profile significantly improves its overall corrosion resistance, effectively resisting erosion from humid, acidic, and alkaline environments, thereby extending its service life. Simultaneously, the reinforcing sleeves embedded in the connection holes enhance the structural strength of the steel profile's connection points, reducing the problem of decreased connection strength due to corrosion. Furthermore, the cooperation between the sliding groove and the slider allows the steel profile to be protected from external impact damage during transportation by using anti-collision sleeves. The position of the anti-collision sleeves can also be easily adjusted according to actual needs, improving the safety and reliability of the steel profile during transportation and use.

[0024] 2. The external impact sleeve of the steel profile effectively absorbs and disperses external impact forces. The protective plate fits tightly against the outer surface of the steel profile, providing basic protection; the pressure-resistant plate further enhances the overall strength of the impact sleeve, resisting external pressure; and several triangularly arranged reinforcing ribs, through their unique structural design, evenly distribute the impact force throughout the entire impact sleeve, reducing the possibility of surface damage due to excessive localized stress. This significantly improves the impact resistance of the steel profile during transportation and use, reduces the risk of corrosion layer damage caused by external collisions, and thus extends the service life of the steel profile.

[0025] 3. The hemispherical design of the slider effectively reduces the frictional resistance between the slider and the groove, making the anti-collision sleeve slide more smoothly on the steel body. At the same time, the hemispherical design also improves the stability of the slider in the groove, reducing the risk of the slider getting stuck or falling out of the groove due to external impact, thereby improving the protective effect of the anti-collision sleeve on the steel body.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a corrosion-resistant reinforced steel profile.

[0034] Reference Figure 1 A corrosion-resistant reinforced steel profile includes a steel profile body 1, the surface of which is coated with a composite anti-corrosion layer 2. The steel profile body 1 has several connecting holes 11, each connecting hole 11 is fitted with a reinforcing sleeve 3, and an anti-collision sleeve 4 is slidably fitted onto the steel profile body 1.

[0035] Reference Figure 2 In this embodiment, the composite anti-corrosion layer 2 includes a primer layer 21, an intermediate paint layer 22, and a topcoat layer 23 stacked sequentially. The primer layer 21 is a zinc-rich primer. After the steel body 1 is shot-blasted and roughened, it is sprayed onto the steel body 1. It can be tightly bonded to the steel body 1 and play an electrochemical protection role. Even if the anti-corrosion layer is partially damaged, zinc can be preferentially corroded, thereby protecting the steel body 1.

[0036] Reference Figure 2 The intermediate paint layer 22 is an epoxy micaceous iron oxide intermediate paint, which contains mica iron oxide flakes that can form a labyrinth effect, effectively preventing the penetration of moisture, oxygen and corrosive media, and enhancing the anti-corrosion effect. The topcoat layer 23 is a fluorocarbon topcoat, which has excellent weather resistance, corrosion resistance and gloss and color retention, and can further protect the primer layer 21 and the intermediate paint layer 22.

[0037] Reference Figure 2The thickness of the primer layer 21, intermediate paint layer 22 and topcoat layer 23 can be adjusted according to actual needs. For example, the thickness of the primer layer 21 is 20-50 micrometers, the thickness of the intermediate paint layer 22 is 80-120 micrometers, and the thickness of the topcoat layer 23 is 40-80 micrometers.

[0038] Reference Figure 1 and Figure 3 The reinforcing sleeve 3 can be made of stainless steel with good wear resistance and corrosion resistance. The outer diameter of the reinforcing sleeve 3 is slightly larger than the diameter of the connecting hole 11. It is fitted onto the connecting hole 11, and its outer wall is tightly fitted with the hole wall of the connecting hole 11. The inner wall has a threaded structure that matches the bolt thread. Assembly is achieved by welding.

[0039] Reference Figure 1 and Figure 4 To reduce the possibility of damage to the composite anti-corrosion layer 2 due to impacts between adjacent steel sections, a protective sleeve 5 is detachably fitted onto the end of the steel section body 1 during transportation. Slide grooves 12 are recessed on opposite side walls of the steel section body 1 along its length, with the ends of the slide grooves 12 extending to the end walls of the steel section body 1. The anti-collision sleeve 4 is slidably fitted onto the steel section body 1 to match its dimensions. A slider 6 is fixedly installed on the side of the anti-collision sleeve 4 facing the slide groove 12. The slider 6 is spherical and slides within the slide groove 12.

[0040] Reference Figure 1 and Figure 4 The anti-collision sleeve 4 is designed in a gate shape, including a protective plate 41, a pressure-resistant plate 42, and reinforcing ribs 43. The protective plate 41 is fitted against the outer surface of the steel body 1, the pressure-resistant plate 42 is fitted over the outer side of the protective plate 41, and several reinforcing ribs 43 are evenly distributed between them. The reinforcing ribs 43 are triangular, with their apex fixed to the pressure-resistant plate 42 and their hypotenuses fitted and fixed to the protective plate 41. This structural design not only improves the overall strength of the anti-collision sleeve 4 but also gives it good impact resistance. The protective plate 41 can be made of flexible materials, such as polyurethane foam, to buffer the impact force during a collision; the pressure-resistant plate 42 can be made of rigid materials, such as glass fiber reinforced plastic, to provide sufficient support.

[0041] Reference Figure 1 and Figure 3 To further improve the structural strength of the steel section connection, an installation groove 13 is formed on the contact surface of the connection part of the steel section body 1, and a sealing strip 7 is inserted into the installation groove 13. The sealing strip 7 has an I-shaped cross-section, with its two protruding parts embedded in the installation groove 13, its middle part extending to the contact surface of the steel section body 1, and its two protruding parts covering the contact surface of the steel section body 1. This design not only improves the sealing performance of the connection part, but also effectively prevents the penetration of moisture and corrosive substances, further enhancing the corrosion resistance of the steel section.

[0042] The implementation principle of a corrosion-resistant reinforced steel profile according to an embodiment of this application is as follows: By setting a multi-layer composite anti-corrosion layer 2 on the surface of the steel profile, the corrosion resistance of the steel profile is improved; by embedding a reinforcing sleeve 3 inside the connecting hole 11, the strength and stability of the connection part are enhanced; by setting an anti-collision sleeve 4 on the outside of the steel profile, the anti-corrosion layer on the surface of the steel profile is effectively protected from damage; and by setting a sealing strip 7 at the connection part of the steel profile, the sealing performance of the connection part is significantly improved, effectively preventing the penetration of moisture and corrosive substances, thereby further improving the corrosion resistance of the steel profile. The combined design of the above structures not only improves the overall performance of the steel profile but also extends its service life, which is of great significance to the safety of building structures.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
