Description

Technical Field

[0001] This application relates to the field of waterproofing and corrosion protection technology for steel structures, and in particular to a waterproofing and corrosion protection structure for steel structure construction. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and undergo rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. During steel structure construction, it is often necessary to weld and fix two steel columns together before use. Because of the special structure of the welded parts, they are susceptible to corrosion and leakage problems due to the external environment. Therefore, waterproofing and anti-corrosion treatment is required for the welded parts, and their waterproofing and anti-corrosion performance directly affects the safety and durability of the entire structure.

[0003] In existing technologies, the welded parts of steel columns are usually treated with a single anti-corrosion coating or waterproof layer, which cannot simultaneously resist electrochemical corrosion, media penetration, and mechanical damage. For example, a single paint coating is prone to aging and cracking due to ultraviolet radiation, and its anti-corrosion and waterproof performance will deteriorate over time. Moreover, after the anti-corrosion coating or waterproof layer is applied, it is directly exposed to the external environment and is easily damaged by external mechanical impacts, scratches, and other factors, thus failing to guarantee that the steel structure can still be used stably in complex environments.

[0004] Therefore, we propose a waterproof and corrosion-resistant structure for steel structure construction to solve the above problems. Utility Model Content

The outer protective coating made of cement mortar can isolate and protect the waterproof layer, ensuring the stability and reliability of the waterproof layer's performance.

[0016] A further feature of this application is that the protective cover includes two frames, both of which have open sides, and the walls of the two frames are fitted together.

The primer coating 201 is made of epoxy zinc-rich primer material, and the intermediate coating 202 is made of epoxy micaceous iron oxide intermediate paint material. The topcoat 203 is made of polyurethane topcoat material. Through the division of labor and cooperation of the primer 201, intermediate coat 202 and topcoat 203, the corrosion resistance of the welded parts of the two steel columns 1 can be enhanced, and its anti-corrosion performance can be improved. Among them, the epoxy zinc-rich primer has excellent anti-rust performance and can form a strong protective film on the surface of the steel column 1, isolating the steel from external corrosive media; the epoxy micaceous iron oxide intermediate coat enhances the adhesion and thickness between the coatings and improves the overall protection capability; the polyurethane topcoat has strong weather resistance and can resist the erosion of ultraviolet rays, rainwater and other substances.

[0038] In this embodiment, the waterproof and anti-corrosion mechanism also includes an outer protective coating 4. The outer protective coating 4 is sprayed and fixed on the outer surface of the waterproof layer 3. The outer protective coating 4 is made of cement mortar, and the waterproof layer 3 is made of waterproof membrane. The waterproof layer 3 made of waterproof membrane can enhance the waterproofness of the welded joint of the two steel columns 1, improve its waterproof effect, and prevent water from penetrating the welded joint of the two steel columns 1.

[0039] In this embodiment, the protective cover 5 includes two frames 501. The sides of the two frames 501 that are close to each other are open, and the walls of the two frames 501 that are close to each other are fitted together. U-shaped clearance grooves 505 are provided at the top and bottom of both frames 501. Two steel columns 1 pass through the corresponding U-shaped clearance grooves 505. Utilizing the synergistic effect of the two frames 501, a physical isolation and protection function can be provided for the waterproof and corrosion-resistant structure, effectively preventing damage from external mechanical collisions and scratches, and providing protection for the steel structure. For additional safety, connecting lugs 502 are fixedly installed on the front and rear outer walls of the two enclosures 501. The two connecting lugs 502 on the same side fit together, and locking bolts 503 are installed through the two connecting lugs 502 on the same side. Locking nuts 504 are threaded on the locking bolts 503. The two enclosures 501 are set with the same shape and size.

The rubber sealing strip 6 ensures that the protective cover 5 and the steel column 1 are tightly fitted, effectively preventing external rainwater, dust and other impurities from entering the interior of the protective cover 5, further improving the waterproof and anti-corrosion performance, and ensuring that the steel structure can still be used stably in complex environments.

[0042] With the above structure, the waterproof and anti-corrosion structure for steel structure construction provided in this application, when used, after welding the two steel columns 1, first use a grinder to grind the welded area smooth and flat, wipe away dust, debris and other impurities on its surface, then spray epoxy zinc-rich primer to form a primer coating 201 on the welded area, then spray epoxy micaceous iron oxide intermediate paint to form an intermediate paint coating 202 after the primer coating 201 has solidified, then spray polyurethane topcoat to form a topcoat coating 203 after the intermediate paint coating 202 has solidified, and finally cover the surface of the topcoat coating 203 completely after the topcoat coating 203 has solidified. After fixing the waterproof membrane, a waterproof layer 3 is formed. Then, cement mortar is sprayed onto the surface of the waterproof layer 3. After the cement mortar solidifies, an outer protective coating 4 is formed, thus completing the construction of the waterproof and anti-corrosion mechanism for the welded parts of the two steel columns 1. Finally, the two frames 501 are locked and fixed to the outside of the welded parts of the two steel columns 1 using locking bolts 503 and locking nuts 504, forming a protective cover 5. This provides physical isolation and protection for the completed waterproof and anti-corrosion mechanism, effectively preventing damage from external mechanical collisions and scratches, and providing additional safety for the steel structure.

[0043] If the protective cover 5 does not affect other construction and use in the later stage, it is not necessary to remove the protective cover 5. If it will affect other construction and use, after a period of time, when the waterproof and anti-corrosion mechanism is stable, the locking nut 504 can be unscrewed out of the locking bolt 503 and the protective cover 5 can be removed.

[0044] By employing a primer coating 201, an intermediate coating 202, and a topcoat coating 203 at the welding points of the two steel columns 1, the corrosion resistance of the welding points can be enhanced, improving their anti-corrosion performance. By setting a waterproof layer 3, the waterproofness of the welding points of the two steel columns 1 can be enhanced, improving their waterproofing effect and preventing moisture from penetrating the welding points of the two steel columns 1. By setting an outer protective coating 4, the waterproof layer 3 can be isolated and protected, preventing damage to the waterproof layer 3 from external sharp objects, ensuring the stability and reliability of the waterproof layer 3's performance, and extending the service life of the waterproof layer 3.
