Description

Technical Field

[0001] This utility model belongs to the field of building equipment, and specifically relates to a building beam and its anti-corrosion structure. Background Technology

[0002] Building beams are horizontal load-bearing components in building structures that bear vertical loads. Over long-term use, building beams are susceptible to performance degradation due to environmental factors. For example, in humid or foggy environments, continuous moisture penetration leads to gradual deterioration of the internal structure of the material. Metal beams are prone to surface peeling and cross-sectional reduction, while concrete beams may experience surface cracking due to steel reinforcement corrosion. In industrial environments, corrosive media in the air slowly erode the beam surface, weakening its load-bearing capacity. Conventional solutions include selecting base materials with stronger weather resistance, such as using alloy steel instead of ordinary steel, or adding mineral admixtures to concrete to increase density. However, these materials are significantly more expensive than conventional materials, have more complex processing techniques, and limited adaptability. Therefore, a new structure is needed to address these technical problems. Utility Model Content

[0004] This utility model is achieved through the following technical solution: a building beam and anti-corrosion structure, comprising: a beam assembly and an anti-corrosion component, wherein the outer surface of the beam assembly is provided with an anti-corrosion component for anti-corrosion, the beam assembly includes a beam body for installation, a mounting plate for fixing is respectively installed on the left and right surfaces of the beam body, and a lifting component for lifting the beam body is installed on the upper surface of the beam body and the lower surface of the mounting plate, and the anti-corrosion component includes a paint layer for anti-corrosion and a repair layer for repair.

[0005] In a preferred embodiment, the beam body includes a main beam and a secondary beam. The upper and lower surfaces of the main beam are integrally formed with a secondary beam. The cross-section of the beam body is I-shaped. The left and right surfaces of the beam body are recessed inward to form grooves.

[0006] In a preferred embodiment, a mounting plate is symmetrically installed at the front end and rear end of the crossbeam body, and the two mounting plates have the same structure. The lifting component includes a lifting ring one and a lifting ring two, and two lifting rings one are symmetrically installed on the lower surface of the mounting plate.

[0007] In a preferred embodiment, a second lifting ring is installed at the center of the upper surface of the crossbeam body via an installation block. The second lifting ring is larger than the first lifting ring. Multiple reinforcing plates are installed at the center of the grooves on the left and right surfaces of the crossbeam body, respectively.

[0008] In a preferred embodiment, the multiple reinforcing plates have the same structure. Painted components are installed on the outer surfaces of the beam body, mounting plate, and reinforcing plates. A repair layer is provided between the painted components. The painted components include a primer layer, a middle coat layer, and a top coat layer. In use, by providing an anti-corrosion component containing a top coat layer and a repair layer on the outside of the beam assembly, the paint layer can effectively isolate external moisture, oxygen, and corrosive media, providing basic and long-lasting anti-corrosion protection for the beam.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 As the first embodiment of this utility model: a building beam and anti-corrosion structure, including: a beam assembly and an anti-corrosion component, the outer surface of the beam assembly is provided with an anti-corrosion component for anti-corrosion, the beam assembly includes a beam body for installation, a mounting plate 120 for fixing is respectively installed on the left and right surfaces of the beam body, and a lifting component for lifting the beam body is installed on the upper surface of the beam body and the lower surface of the mounting plate 120, and the anti-corrosion component includes a paint layer 230 for anti-corrosion and a repair layer 220 for repair.

[0022] The beam body includes a main beam 100 and a secondary beam 110. The upper and lower surfaces of the main beam 100 are integrally formed with a secondary beam 110. The cross section of the beam body is I-shaped. The left and right surfaces of the beam body are recessed inward to form grooves.

[0023] A mounting plate 120 is symmetrically installed at the front and rear ends of the crossbeam body. The two mounting plates 120 have the same structure. The lifting components include a lifting ring 140 and a lifting ring 160. Two lifting rings 140 are symmetrically installed on the lower surface of the mounting plate 120.

[0024] A second lifting ring 160 is installed at the center of the upper surface of the crossbeam body via a mounting block 150. The second lifting ring 160 is larger than the first lifting ring 140. Multiple reinforcing plates 130 are installed at the center of the grooves on the left and right surfaces of the crossbeam body, respectively.

[0025] During use, the user can lift and transport the crossbeam body using the lifting devices on the upper surface of the crossbeam body and the lower surface of the mounting plate 120, and then install it. When installing the crossbeam body using the lifting devices, the mounting plates 120 at the front and rear ends of the crossbeam body can provide an installation foundation for the crossbeam body. At the same time, the reinforcing plates 130 in the grooves on the left and right surfaces of the crossbeam body can provide a certain degree of protection when the crossbeam is prestressed, making the crossbeam body more stable during use. Since the crossbeam body provides a stable load-bearing foundation during use, the left and right mounting plates 120 can be reliably connected to other building components to enhance the overall structural stability. The lifting devices on the upper side and the lower side of the mounting plate 120 provide convenient and safe stress points for the installation and transportation of the crossbeam. During use, the positioning and installation of the crossbeam can be completed efficiently, improving the convenience and efficiency of construction.

[0026] Please see Figures 1 to 4 As a second embodiment of the present utility model: based on the description in the above embodiments, further, the multiple reinforcing plates 130 have the same structure, and the outer surfaces of the beam body, the mounting plate 120 and the reinforcing plate 130 are equipped with painted parts, and a repair layer 220 is provided between the painted parts. The painted parts include a primer layer 200, a middle paint layer 210 and a paint layer 230.

[0027] A primer layer 200 is installed on the outer surface of the beam body, mounting plate 120 and reinforcing plate 130, and a middle paint layer 210 is installed on the outer surface of the primer layer 200 away from the beam body, mounting plate 120 and reinforcing plate 130.

[0028] Repair layer 220 has a repair capsule inside. Repair layer 220 is installed on the side of intermediate paint layer 210 away from primer layer 200. Topcoat layer 230 is installed on the side of repair layer 220 away from intermediate paint layer 210.

[0029] During use, the crossbeam body may be corroded by external factors. The anti-corrosion components on the outer surface of the crossbeam body intercept these external factors, preventing them from directly affecting the crossbeam body and other components, thus achieving an anti-corrosion effect. Because the anti-corrosion components, including a paint layer 230 and a repair layer 220, are installed on the outside of the crossbeam assembly, the paint layer 230 effectively isolates external moisture, oxygen, and corrosive media, providing basic and long-lasting anti-corrosion protection for the crossbeam. The repair layer 220 can promptly repair minor damage to the paint layer 230 (the repair layer 220 contains microcapsules filled with anti-corrosion repair fluid; when the paint layer 230 is damaged and also damages the repair layer 220, the capsules inside the repair layer 220 rupture, releasing the repair fluid). Then, the broken parts are repaired and cured to increase the anti-corrosion effect. The above-mentioned repair layer technology is existing technology, and its specific structure and working principle are existing technology, which will not be elaborated here. It prevents the further spread of corrosion. During use, it can significantly slow down the rust aging rate of the beam and extend its service life. (When using it, the primer layer 200 is selected with an epoxy zinc-rich primer with a zinc content of ≥80%. It forms electrochemical protection by means of the sacrificial anode effect of zinc and effectively isolates moisture. At the same time, the intermediate paint layer 210 is made of epoxy micaceous iron oxide paint reinforced with glass fiber cloth to build a dense barrier to resist acid and alkali corrosion. The topcoat layer 230 is flexibly selected according to the use environment. For outdoor environments, fluorocarbon paint that is resistant to ultraviolet aging is selected, and for industrial environments, polyurethane paint that is resistant to chemical corrosion is selected. Users can choose the above according to the actual situation, which will not be elaborated here.)

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
