Description

Technical Field

[0001] This utility model relates to the field of steel formwork processing and flipping technology, and in particular to a corrosion-resistant steel component structure. Background Technology

[0002] Steel components are a general term for steel structures formed by welding and assembling I-beams, angle steel, or other shaped steel materials. They are mainly used in the frames or load-bearing structures of buildings. Areas of stress concentration in steel components are prone to corrosion fatigue and require optimization. Adjusting the structural shape, dimensions, and connection methods can make stress distribution more uniform and reduce the risk of corrosion.

[0003] Existing corrosion-resistant steel structural components, such as the one disclosed in CN221567451U, use support rods and connecting rods to protect the bolts in the steel components from corrosion. In fact, the bolts need to be designed for corrosion protection because stress concentration areas of I-beams are prone to corrosion fatigue, which seriously affects the service life of the steel components. Therefore, corrosion protection design is necessary. Utility Model Content

[0004] The purpose of this invention is to solve the problem of corrosion fatigue easily occurring in the stress-concentrated parts of steel components in the prior art, and to propose a corrosion-resistant steel component structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrosion-resistant steel structural member includes an I-beam. The I-beam includes a vertical plate and two horizontal plates integrally connected to both ends of the vertical plate. Multiple support members for reinforcing the connection between the vertical and horizontal plates are evenly installed at the connection points. Mounting assemblies for fixing the support members are fixedly installed on both the vertical and horizontal plates. Protective plates for corrosion and oxidation prevention are provided on the horizontal plates. The mounting assemblies include fixing members fixedly installed on the I-beam. A cavity is formed within the fixing member. Two rectangular holes are symmetrically formed at the bottom of the cavity. Limiting rods are symmetrically and vertically fixedly installed at both ends of the cavity. A pressing member for fixing the support members is movably fitted within the cavity. Both ends of the pressing member are movably fitted with the limiting rods, and the bottom end of the pressing member is movably fitted with the rectangular holes. A tension spring is provided between the top of the pressing member and the top wall of the cavity. A rotating member with a threaded fitting for the pressing member is also rotatably installed on the fixing member.

[0007] Preferably, the top end of the rotating component is configured as a rotating handle, and the bottom end of the rotating component is threaded.

[0008] Preferably, the horizontal plate has an installation groove for installing protective plates. The installation groove includes a rectangular groove and a slot on the horizontal plate, and the rectangular groove and the slot are connected.

[0009] Preferably, the protective plate includes a plate body installed in a rectangular groove, and multiple locking blocks are symmetrically and integrally connected to both ends of the plate body.

[0010] Preferably, the support includes two fixed ends that are respectively connected to the vertical plate and the horizontal plate, and an inclined surface is integrally connected between the two fixed ends, with the included angle between the fixed ends and the inclined surface being 135°.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. This utility model provides support members evenly distributed at the connection between the horizontal and vertical plates of the I-beam. The stress concentration at the connection between the horizontal and vertical plates is dispersed by the support members, which strengthens the I-beam, prevents corrosion at the connection, and extends the service life of the I-beam.

[0013] 2. This utility model extends the service life of I-beams by applying passivating spray anti-corrosion and anti-oxidation materials at the connection between the horizontal and vertical plates, and by installing protective plates at stress concentration points on the horizontal plates to protect the I-beams from corrosion and oxidation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A corrosion-resistant steel structural member includes an I-beam 1, which includes a vertical plate 11 and two horizontal plates 12 integrally connected to both ends of the vertical plate 11. The stress concentration and easily oxidized and corroded parts of the I-beam 1 are usually at the connection between the vertical plate 11 and the horizontal plate 12. A plastic coating is melted and solidified at the connection between the vertical plate 11 and the horizontal plate 12 to improve the corrosion resistance, wear resistance and insulation of the connection between the vertical plate 11 and the horizontal plate 12.

[0026] Multiple support members 2 are evenly installed at the connection between the vertical plate 11 and the horizontal plate 12 to reinforce the connection between the vertical plate 11 and the horizontal plate 12. Each support member 2 includes two fixed ends 22 that are respectively connected to the vertical plate 11 and the horizontal plate 12. An inclined surface 21 is integrally connected between the two fixed ends 22. The angle between the fixed ends 22 and the inclined surface 21 is 135°. Multiple support members 2 are evenly installed at the connection between the vertical plate 11 and the horizontal plate 12. These support members 2 not only enhance the stability of the connection, but also effectively disperse stress and extend the service life of the I-beam 1.

[0027] Mounting components 3 for fixing support members 2 are fixedly installed on both the vertical plate 11 and the horizontal plate 12. It should be noted that the mounting components 3 include fixing members 31 fixedly installed on the I-beam 1. A cavity 32 is opened in the fixing member 31. Two rectangular holes 33 are symmetrically opened at the bottom of the cavity 32. Limiting rods 34 are symmetrically and vertically fixed at both ends of the cavity 32. A pressing member 35 for fixing support members 2 is movably fitted in the cavity 32. The cavity 32, the two symmetrically opened rectangular holes 33 and the symmetrically and vertically fixed limiting rods 34 cooperate with each other to form a stable guiding system, ensuring that the pressing member 35 moves linearly back and forth in the cavity 32.

[0028] The two ends of the pressing member 35 are movably fitted with the limiting rod 34, and the bottom end of the pressing member 35 is movably fitted with the rectangular hole 33. A tension spring 36 is provided between the top of the pressing member 35 and the top cavity wall of the cavity 32. The tension spring 36 provides the pressing member 35 with the force to press against the support member 2. Importantly, the tension spring 36 is symmetrically designed, which makes the movement of the pressing member 35 more stable. A rotating member 37 with a threaded fitting is also rotatably installed on the fixing member 31. The top end of the rotating member 37 is set as a rotating handle, and the bottom end of the rotating member 37 is threaded. By rotating the rotating member 37, the position of the pressing member 35 can be precisely adjusted, thereby releasing the fixing support member 2.

[0029] The horizontal plate 12 is provided with a protective plate 5 for corrosion and oxidation prevention. The main body of the plate 51 is made of plastic-coated steel plate material, which has excellent corrosion and oxidation prevention performance, so as to isolate the steel from the external environment and significantly improve the corrosion resistance and service life of the I-beam 1, and effectively protect the I-beam 1 from the corrosion of the external environment.

[0030] The horizontal plate 12 has an installation groove 4 for installing the protective plate 5. The groove wall is coated with a plastic coating. The installation groove 4 ensures the secure installation of the protective plate 5 and facilitates later maintenance and replacement of the protective plate 5. The installation groove 4 includes a rectangular groove 41 and a locking slot 42 on the horizontal plate 12. The locking slot 42 enables quick positioning and fixing of the protective plate 5, improving installation efficiency. The rectangular groove 41 and the locking slot 42 are connected. The protective plate 5 includes a plate body 51 installed in the rectangular groove 41. Multiple locking blocks 52 are symmetrically and integrally connected to both ends of the plate body 51. The locking blocks 52 cooperate with the locking slot 42 to securely fix the protective plate 5.

[0031] The main body 51 of this utility model is bent. The locking block 52 is inserted into the locking groove 42 to complete the installation of the protective plate 5 in the mounting groove 4. The rotating component 37 is rotated, and the pressing component 35 moves linearly in the direction of the compression tension spring 36 to provide space for the support component 2 to be placed between the two mounting components 3. The fixed end 22 of the support component 2 is pushed into the bottom of the two mounting components 3 respectively. The rotating component 37 is rotated in the opposite direction, and the pressing component 35 moves in the direction close to the fixed end 22 to fix the support component 2 on the I-beam 1.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
