Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, and in particular to a reinforced steel structure that can be quickly assembled. Background Technology
[0002] Steel structures are structures composed of steel materials. In fields such as construction, bridges, and machinery, reinforced steel structures are widely used in load-bearing or critical structural components due to their high strength, rigidity, and resistance to deformation. With the increasing demand for efficient construction and modular building, rapidly assembleable reinforced steel structures have become a research hotspot. Through bolted connections, snap-fit joints, and mortise and tenon joints, they significantly shorten installation cycles and reduce on-site construction difficulties.
[0003] Currently, existing reinforced steel structures that can be quickly assembled have been found to have at least the following technical problems in actual use;
[0004] The "strengthened" characteristic of reinforced steel structures relies on overall rigidity. However, existing rapid assembly structures mostly use segmented splicing, resulting in numerous quick-connect components. In humid and dusty environments (such as coastal warehouses, temporary distribution centers, and modular production workshops, which require rapid production and long-term resistance to salt spray / typhoons, especially suitable for time-sensitive projects like land reclamation), the contact surfaces of quick-connect components (such as clips and pins) are prone to rust or dust accumulation. The current solution is to spray anti-rust coatings. However, at the connection points of reinforced steel structures, friction between the various components during installation causes the anti-rust coating to wear down. Furthermore, after prolonged use, the connection points rub against each other due to vibrations (machine operation vibrations, vibrations caused by personnel movement, etc.). (The steel structure as a whole has a margin of movement to allow for slight swaying for seismic performance), further abrading the anti-rust coating. Over time, this area will come into contact with moisture and rust, becoming a breakthrough point for corrosion. This significantly affects the stability of the steel structure connection points, weakens the overall supporting structure strength, and causes considerable damage to the steel structure building as a whole. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a reinforced steel structure that can be quickly assembled, solving the problem that existing reinforced steel structures that can be quickly assembled will have their anti-rust coating structure damaged by friction, ultimately affecting the overall support strength of the steel structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rapidly assembled reinforced steel structure includes two I-beams and two connectors between them. Each I-beam has four first through holes and one Y-shaped through hole at its top, near one end. Each connector has two first semi-grooves at both ends of its top. Each I-beam has two second semi-grooves on its inner bottom surface, near one end. Each connector has two second through holes at both ends of its inner bottom surface. Each connector has two recesses on its top side, near one end. The eight first through holes are aligned with the eight first semi-grooves, the four second through holes are aligned with the four second semi-grooves, and the two ends of the two Y-shaped through holes are aligned with the four recesses. Anti-oxidation mechanisms are placed within the first semi-grooves, second semi-grooves, and recesses. Each anti-oxidation mechanism includes a first biodegradable carrier filled with an antioxidant.
[0008] Preferably, the first biodegradable carrier placed in the first half-groove has three-quarters of its portion located inside the first through hole and one-quarter of its portion located inside the first half-groove.
[0009] Preferably, the first biodegradable carrier placed in the second half-groove has three-quarters of its portion located inside the second through hole and one-quarter of its portion located inside the second half-groove.
[0010] Preferably, the first biodegradable carrier placed in the groove has three-quarters of its portion located inside the Y-shaped through-hole and one-quarter of its portion located inside the groove.
[0011] Preferably, the anti-oxidation mechanism can be a second biodegradable carrier, which contains an anti-oxidant.
[0012] Preferably, the anti-oxidation mechanism can be a third biodegradable carrier, which contains an anti-oxidant.
[0013] Preferably, the anti-oxidation mechanism can be two miniature anti-oxidation components, each including a first biodegradable carrier or a second biodegradable carrier, with an anti-oxidant filled inside the first and second biodegradable carriers.
[0014] Preferably, the micro-antioxidant component including the first degradable carrier is located at the bottom, and the micro-antioxidant component including the second degradable carrier is located at the top, wherein the thickness of the first degradable carrier and the second degradable carrier in the micro-antioxidant component is half of the normal thickness.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In this application, when two I-beams are quickly assembled using connectors, the connectors may damage the paint on the I-beams. After installation, an antioxidant can be directly injected into the connection between the connector and the I-beam through the first through hole, the Y-shaped through hole, and the second through hole. After prolonged use, the steel structure will vibrate due to mechanical operation, causing the antioxidant to wear away. The first biodegradable carrier will be degraded by microorganisms during contact with the outside environment. If a hole appears in the first biodegradable carrier, the antioxidant inside will flow out and seep into the gap between the I-beam and the connector through the first through hole, the Y-shaped through hole, and the second through hole, re-covering most of the parts of the I-beam that are in contact with the outside environment, thus achieving an antioxidant effect. The antioxidant mechanism only needs to be filled once a year. Attached Figure Description

[0027] This application provides a quick-assembly reinforced steel structure, which effectively solves the problem that existing quick-assembly reinforced steel structures suffer damage to the anti-rust coating due to friction, ultimately affecting the overall support strength of the steel structure.
[0028] The device includes two I-beams 1, with two connectors 2 between them. Each of the two I-beams 1 has four first through holes 3 and one Y-shaped through hole 4 at the top of its adjacent ends. Each of the two connectors 2 has two first semi-grooves 5 at both ends of its top. Each of the two I-beams 1 has two second semi-grooves 6 at the inner bottom surface of its adjacent ends. Each of the two connectors 2 has two second through holes 7 at both ends of its inner bottom surface. Each of the two connectors 2 has two grooves 8 on one side of its top that are close to each other. The eight first through holes 3 are aligned with the eight first semi-grooves 5, the four second through holes 7 are aligned with the four second semi-grooves 6, and the two ends of the two Y-shaped through holes 4 are aligned with the four grooves 8. Anti-oxidation mechanisms are placed in the first semi-grooves 5, the second semi-grooves 6, and the grooves 8. Each anti-oxidation mechanism includes a first biodegradable carrier 9, which is filled with an anti-oxidant 10.
[0029] The first biodegradable carrier 9, placed in the first half-groove 5, has three-quarters of its portion located inside the first through hole 3 and one-quarter of its portion located inside the first half-groove 5.
[0030] The first biodegradable carrier 9, placed in the second half-groove 6, has three-quarters of its portion located inside the second through hole 7 and one-quarter of its portion located inside the second half-groove 6.
[0031] The first biodegradable carrier 9, placed in the groove 8, has three-quarters of its portion located inside the Y-shaped through hole 4 and one-quarter of its portion located inside the groove 8.
[0032] The anti-oxidation mechanism can be a second biodegradable carrier 11, which contains an anti-oxidant 10.
[0033] The anti-oxidation mechanism can be a third biodegradable carrier 12, which contains an anti-oxidant 10.
[0034] The anti-oxidation mechanism can be two miniature anti-oxidation components, each including a first biodegradable carrier 9 or a second biodegradable carrier 11, with an anti-oxidant 10 filled inside the first biodegradable carrier 9 and the second biodegradable carrier 11.
[0035] The micro-antioxidant component including the first degradable carrier 9 is located below, and the micro-antioxidant component including the second degradable carrier 11 is located above. The thickness of the first degradable carrier 9 and the second degradable carrier 11 in the micro-antioxidant component is half that of the normal state.
[0036] The first biodegradable carrier 9 is a chitosan composite carrier, using corn starch (60%) and chitosan (30%) as the base material, with 10% glycerol added as a plasticizer, and is made into microcapsules (0.5-1 mm in diameter) through an emulsification-crosslinking method. The second biodegradable carrier 11 is a PBAT / PLA blended sustained-release carrier, made by blending polybutylene adipate (PBAT, 70%) and polylactic acid (PLA, 30%), and is extruded into a tubular carrier (wall thickness 0.3-0.5 mm, inner diameter...). The tube is filled with a medium-efficiency antioxidant (such as molybdate or organophosphonate) and the third biodegradable carrier 12 is a PBS-nanomontmorillonite composite slow-release carrier. It uses polybutylene succinate (PBS, 85%) as the base material and adds 15% nanomontmorillonite (to enhance mechanical properties and water resistance). It is molded into a gasket with a thickness of 1-2 mm (the shape matches the contact surface of the connection part) and embeds a long-lasting antioxidant (such as vapor phase corrosion inhibitor or organic amine compound) inside.
[0037] When antioxidant 10 is used on the first biodegradable carrier 9, it is a fast-acting antioxidant (such as sodium nitrite or benzotriazole); when antioxidant 10 is used on the second biodegradable carrier 11, it is a medium-acting antioxidant (such as molybdate or organophosphonate); and when antioxidant 10 is used on the third biodegradable carrier 12, it is a long-acting antioxidant (such as vapor phase corrosion inhibitor or organic amine compound).
[0038] I-beam 1 is the main body of the steel structure, and is used for assembly and connection of connectors 2.
[0039] Connector 2 is used to connect two I-beams 1 to achieve rapid assembly.
[0040] The first through hole 3 is used to inject antioxidant 10 into the connection between the connector 2 and the I-beam 1, and also accommodates three-quarters of the first biodegradable carrier 9.
[0041] The Y-shaped through hole 4 is used to inject the antioxidant 10 into the connection between the connector 2 and the I-beam 1, and also accommodates three-quarters of the first biodegradable carrier 9.
[0042] The first half-slot 5 is used to place the anti-oxidation mechanism and to accommodate one-quarter of the first degradable carrier 9.
[0043] The second half-slot 6 is used to place the anti-oxidation mechanism and to accommodate a quarter of the first degradable carrier 9.
[0044] The second through hole 7 is used to inject antioxidant 10 into the connection between the connector 2 and the I-beam 1, and also accommodates three-quarters of the first biodegradable carrier 9.
[0045] The groove 8 is used to place the anti-oxidation mechanism and to accommodate a quarter portion 8 of the first degradable carrier 9.
[0046] The anti-oxidation mechanism is used to load the anti-oxidant 10, and the anti-oxidant 10 is released through the degradation of the degradable carrier to prevent oxidation and rust at the connection points.
[0047] The first biodegradable carrier 9 is filled with antioxidant 10, which degrades in 3-6 months and releases antioxidant 10 after degradation, making it suitable for scenarios with a lot of vibration.
[0048] Antioxidant 10 is used to cover the connection between the I-beam 1 and the connector 2 to prevent oxidation and rust.
[0049] The second biodegradable carrier 11 is filled with antioxidant 10, which degrades in 1 to 2 years and is suitable for scenarios with low vibration. After degradation, antioxidant 10 is released.
[0050] The third biodegradable carrier 12 is filled with antioxidant 10, which degrades in 3 to 4 years and is suitable for scenarios with long-term stable conditions. After degradation, antioxidant 10 is released.
[0051] The miniature anti-oxidation component is composed of a first biodegradable carrier 9 or a second biodegradable carrier 11, and is filled with an anti-oxidant 10 inside. It is placed on the top and bottom and is suitable for environments with a lot of vibration interference, so as to realize the phased release of the anti-oxidant 10. Example
[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in this application, when the two I-beams 1 are quickly assembled using the connector 2, the connector 2 will damage the paint surface of the I-beams 1. After installation, the antioxidant 10 can be directly injected into the connection between the connector 2 and the I-beams 1 through the first through hole 3, the Y-shaped through hole 4 and the second through hole 7. After long-term use, the steel structure will vibrate due to mechanical operation, which will wear down the antioxidant 10. The first biodegradable carrier 9 will be degraded by microorganisms during contact with the outside world (3-6 months). During this process, if the first biodegradable carrier 9 has a hole, the antioxidant 10 inside will flow out from the first biodegradable carrier 9 and seep into the gap between the I-beams 1 and the connector 2 through the first through hole 3, the Y-shaped through hole 4 and the second through hole 7, and re-cover most of the parts of the I-beams 1 that are in contact with the outside world, thus achieving an anti-oxidation effect. The anti-oxidation mechanism only needs to be filled once a year by the staff. Example
[0053] like Figure 1 , Figure 4 and Figure 6As shown, in some scenarios used in exhibition halls and convention centers, there is no need to place machinery, only some people walking around, which will cause slight vibration of the steel structure. However, the amplitude and frequency of the vibration will not be greater than those of the factory building used to place machinery. Therefore, there will be no frequent friction between the I-beam 1 and the connecting parts 2, and the impact on the paint surface will be small. The first biodegradable carrier 9 degrades too quickly and cannot play a significant filling role. At this time, the first biodegradable carrier 9 can be replaced with the second biodegradable carrier 11 to extend the degradation time. The second biodegradable carrier 11 will degrade after 1 to 2 years. The antioxidant 10 inside the second biodegradable carrier 11 will flow out and cover the connecting parts of the I-beam 1. The staff only needs to fill the antioxidant mechanism once every four years. Example
[0054] like Figure 1 , Figure 4 and Figure 7 As shown, when the I-beam 1 is used in some factories that are only used for long-term purposes, there is no need to place large machinery or for people to walk around. The steel structure of the factory is in a stable state for a long time. At this time, the second biodegradable carrier 11 can be replaced with the third biodegradable carrier 12. The third biodegradable carrier 12 will degrade in the natural environment for 3 to 4 years. The outflowing anti-oxidant 10 covers most of the space at the connection part of the I-beam 1. The staff only needs to fill the anti-oxidation mechanism once every six years. Example
[0055] like Figure 1 , Figure 4 and Figure 8 As shown, when used in environments with a lot of vibration interference, two miniature anti-oxidation components can be used instead of other anti-oxidation mechanisms. The first biodegradable carrier 9 degrades after about 2 months of contact with the outside world, and the second biodegradable carrier 11 degrades after about 4 months of contact with the outside world. Every two months, the anti-oxidant 10 penetrates into the connection part of the I-beam 1 to prevent oxidation and rust.
[0056] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
