TECHNICAL FIELD
[0001] The application relates to the technical field of profile steel, in particular to a high-corrosion-resistance reinforced profile steel. BACKGROUND
[0002] At present, the widely used profile steel in the market mainly includes ordinary carbon structural steel and low-alloy high-strength structural steel. Although these steels have high strength and good processing performance, they are prone to corrosion in high humidity, salt spray and other harsh environments, resulting in shortened service life and increased maintenance cost.
[0003] In order to improve the corrosion resistance of the profile steel, the existing technical means mainly include surface coating treatment, addition of corrosion-resistant elements, composite material coating and the like. Among them, the surface coating treatment is the most common method, which forms a protective film on the surface of the profile steel through spraying, electroplating and the like, so as to prevent the corrosion medium from contacting the base material. However, the single surface coating treatment is prone to physical and chemical damage, has poor durability, and when cracking occurs, the anti-corrosion effect is easily affected.

By arranging snap-on plates, connecting rods and connecting holes, quick connection and convenient installation of the reinforced steel are achieved, without the need for complicated welding or bolt connection processes, greatly improving construction efficiency and reducing installation costs. By opening countersunk holes on the outer surface of the I-beam and inserting threaded rods and nuts to fix the C-type transition sleeve, the flatness of the overall surface is ensured, and the problem of affecting the appearance and use effect due to protruding fixings is avoided.
[0008] Furthermore, the outer surface of the I-shaped steel is provided with a plurality of countersunk holes penetrating the surface sleeve.
[0009] Through the above solution and the provision of the countersunk holes, the flatness of the entire surface can be ensured.
[0010] Furthermore, a threaded rod is inserted into the interior of each countersunk hole, and nuts are threadedly connected at both ends of each threaded rod.
[0011] Through the above solution, the purpose of fixing the C-type transition sleeve can be achieved by setting the nut.
[0012] Furthermore, each group of the first reinforcing ribs is meshedly connected with a group of the second reinforcing ribs adjacent thereto.
[0013] Through the above solution and the above arrangement, the contact area between the transition plate and the I-shaped steel can be increased, thereby effectively preventing the transition plate from deflecting.
[0014] Furthermore, each of the transition plates and C-shaped transition sleeves is made of stainless steel.
[0015] Through the above scheme and the above arrangement, the stainless steel has good corrosion resistance and strength, and can effectively extend the service life of the reinforced steel.
[0016] Furthermore, each of the surface layers is made of high-density polyethylene material.
[0017] Through the above scheme and the above arrangement, the high-density polyethylene material has excellent chemical corrosion resistance and wear resistance, and can provide additional protection for the reinforced steel.
[0018] Furthermore, an anti-corrosion layer is provided on the outer surface of the surface sleeve, and the anti-corrosion layer is coated with fluorocarbon paint through an electrostatic spraying process.
[0019] Through the above scheme and the above setting, the fluorocarbon coating has excellent weather resistance and corrosion resistance, which can further enhance the corrosion resistance of the reinforced steel section, extend its service life, and improve its appearance quality.
[0020] Furthermore, each of the connecting pieces is made of elastic material.
[0021] Through the above solution, it can be squeezed and moved closer to the connecting rod during insertion, and reset when no longer under pressure, thereby achieving the effect of automatic limiting.
[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

Through the above arrangement, the contact area of the transition plate 3 and the I-shaped steel 1 can be increased, thereby effectively preventing the transition plate 3 from deviating.
[0034] Please refer to Figure 4 , Figure 5 and Figure 6 The outer surfaces of the plurality of C-shaped transition sleeves 5 are in sliding connection with a same surface sleeve 6, the right side surfaces of the two C-shaped transition sleeves 5 located at the leftmost side are each fixedly connected with a group of connecting rods 7, the right ends of each connecting rod 7 are each fixedly connected with a plurality of circumferentially arrayed clamping pieces 8, the left side surfaces of the two C-shaped transition sleeves 5 located at the rightmost side are each provided with a group of connecting holes 9. Through the arrangement of the clamping pieces 8, the connecting rods 7 and the connecting holes 9, the purpose of quick connection can be achieved. Each clamping piece 8 is made of elastic material and can be pressed together with the connecting rod 7 when inserted, and can be reset when not under pressure, thereby achieving the effect of automatic limiting.
[0035] Please refer to Figure 1 , Figure 2 and Figure 3The outer surface of the I-beam 1 is provided with multiple groups of countersunk holes 10 that penetrate the surface sleeve 6. The setting of the countersunk holes 10 can ensure the flatness of the overall surface. A threaded rod 11 is inserted into the inside of each countersunk hole 10, and each end of each threaded rod 11 is threadedly connected with a nut 12. The setting of the nut 12 can achieve the purpose of fixing the C-type transition sleeve 5.
[0036] See also Figure 1 、 Figure 2 and Figure 6 Each surface sleeve 6 is made of high-density polyethylene material. Through the above setting, the high-density polyethylene material has excellent chemical corrosion resistance and wear resistance, and can provide additional protection for the reinforced steel. The outer surface of the surface sleeve 6 is provided with an anti-corrosion layer, and the anti-corrosion layer is a fluorocarbon coating applied by an electrostatic spraying process. Through the above setting, the fluorocarbon coating has excellent weather resistance and corrosion resistance, which can further enhance the corrosion resistance of the reinforced steel, extend its service life, and improve its appearance quality.
[0037] In this embodiment, a highly corrosion-resistant reinforced steel is made of stainless steel to make the transition plate 3 and the C-type transition sleeve 5, and high-density polyethylene to make the surface sleeve 6, and supplemented with a fluorocarbon coating anti-corrosion layer, which effectively improves the corrosion resistance of the overall structure, especially in harsh environments such as high humidity and salt spray, which can significantly extend the service life and reduce maintenance costs. By arranging the first reinforcing ribs 2 with equal distances and vertical arrangement on the left and right sides of the I-shaped steel 1, and arranging the second reinforcing ribs 4 on the transition plate 3 and engaging with the first reinforcing ribs 2, the I-shaped steel is significantly enhanced. 1, while avoiding the deviation of the transition plate 3, ensuring corrosion resistance, and improving the bearing capacity of the overall structure. By setting the clamping piece 8, the connecting rod 7 and the connecting hole 9, the rapid connection and convenient installation of the reinforced steel are realized, without the need for complicated welding or bolt connection process, which greatly improves the construction efficiency and reduces the installation cost.

[0038] The working principle of the above embodiment is as follows: first, the I-beam 1 serves as the main structure, and a group of equidistant and vertically arranged first reinforcing ribs 2 are fixedly connected to its left and right side surfaces. The first reinforcing ribs 2 not only enhance the structural strength of the I-beam 1, but also provide a meshing basis for subsequent connections. Then, two transition plates 3 are installed on the left and right sides of the I-beam 1, and one side of each is fixedly connected to a group of equidistant and vertically arranged second reinforcing ribs 4. These second reinforcing ribs 4 mesh with the first reinforcing ribs 2, which increases the contact area between the transition plate 3 and the I-beam 1 and effectively avoids the transition plate 3 from shifting during use. The C-type transition sleeve 5 is fixedly connected to the top and bottom ends of the transition plate 3, and they are slidably connected to the outer surface of the I-beam 1, and are located on the right side of the C-type transition sleeve 5 on the far left. The surface is fixedly connected with a group of connecting rods 7, and the right end of the connecting rod 7 is fixedly connected with a plurality of circular array snap-in pieces 8, and the left side of the C-type transition sleeve 5 located on the far right is provided with a group of connecting holes 9. When two reinforced steel sections need to be connected, it is only necessary to insert the snap-in pieces 8 into the connecting holes 9. Due to the elastic material properties, the snap-in pieces 8 will be squeezed close to the connecting rod 7 when inserted, and will reset when not under pressure to achieve the effect of automatic limiting, thereby realizing quick connection. In order to ensure the stability and flatness of the overall structure, the outer surface of the I-beam 1 is also provided with a plurality of groups of countersunk holes 10 that pass through the surface sleeve 6, and the C-type transition sleeve 5 is fixed by inserting threaded rods 11 and nuts 12. This design not only ensures the flatness of the overall surface, but also avoids the problem of affecting the appearance and use effect due to the protrusion of the fixing parts.
