Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a prefabricated steel structure connection component. Background Technology

[0002] Steel structure is a building structure constructed primarily of steel. It boasts advantages such as high strength, lightweight, good seismic performance, fast construction speed, and recyclability, and is widely used in various types of buildings, including high-rise buildings, long-span bridges, industrial plants, and stadiums.

[0003] In prefabricated steel structure buildings, the connection quality of steel structure components directly affects the stability and safety of the entire building structure.

[0004] Traditional steel structure connection methods, such as welding, involve complex construction processes, require specialized welders and equipment, and the welding quality is greatly affected by environmental and human factors, making it prone to welding defects that affect the reliability of the structure. In addition, existing connectors can only connect specific round and square tubes and cannot be freely combined, which increases the difficulty of maintenance and modification due to a lack of versatility. If the building needs to be expanded or modified in the future, incompatibility issues with the connection components may be encountered.

[0005] To address the above issues, we have introduced a prefabricated steel structure connection component. Utility Model Content

[0006] This utility model discloses a prefabricated steel structure connection component, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A prefabricated steel structure connection assembly includes two main connecting parts, a round tube connection assembly, and a square tube connection assembly. The two main connecting parts are used together. The round tube connection assembly and the square tube connection assembly are both set on the corresponding main connecting parts. Side ears are fixedly connected to both sides of each main connecting part. The two corresponding side ears are connected to each other by a plurality of first fastening screws.

[0009] First, the two main connecting parts are respectively fitted onto the ends of the two steel beams to make them fit together. Then, the construction workers pass the first fastening screw through the screw hole on the corresponding side ear and tighten the screw to firmly fix the two main connecting parts together, completing the initial connection of the steel beams and laying the foundation for connecting other structural components through round tube connecting components and square tube connecting components.

[0010] In a preferred embodiment, the circular tube connection assembly includes a lower clamp, an upper clamp, and second fastening screws. The lower clamp is fixedly connected to the top of the corresponding main body connector, and the upper clamp is used in conjunction with the lower clamp through a plurality of second fastening screws.

[0011] When connecting a circular pipe structure to an installed steel beam, first place one end of the pipe on the lower clamp, then place the upper clamp on top of the pipe to align them. Then, the workers screw the second fastening screw into the corresponding screw holes of the lower and upper clamps, gradually tightening them to achieve a stable connection between the pipe and the steel beam. This method can be used, for example, when building a circular ventilation duct support for a factory.

[0012] In a preferred embodiment, the square tube connecting assembly includes a square tube connector, four limiting screws, two support frames, and two rotating shafts. The two support frames are fixedly connected to the main connector, and the two rotating shafts are rotatably connected to the interior of their respective support frames. The square tube connector is fixedly connected between the two rotating shafts, and the four limiting screws symmetrically pass through the interior of the square tube connector.

[0013] When installing the wall keel in the steel structure workshop, the square tube needs to be connected to the steel beam. The construction workers first rotate the square tube connector to adjust its angle so that it matches the installation position of the square tube. Then, one end of the square tube is inserted into the square tube connector. By screwing in the limiting screw, the end of the limiting screw abuts against the inner wall of the square tube, thereby fixing the square tube in the square tube connector and completing the connection between the square tube and the steel beam.

[0014] In a preferred embodiment, a fixing plate is fixedly connected to each of the two support frames on opposite sides. The fixing plate is threaded with a limit screw inside. Limit holes are provided on the outer side of each rotating shaft. The limit screws are used in conjunction with the corresponding limit holes.

[0015] To prevent the square tube connector from rotating arbitrarily after the angle is adjusted, the installer rotates the limiting screw on the fixing plate so that its end is aligned with and inserted into the limiting hole on the rotating shaft. The rotating shaft is locked, and the angle of the square tube connector is fixed, ensuring the stability of the connecting components during the installation of the square tube.

[0016] In a preferred embodiment, the inner walls of the main connecting parts are all fixedly connected with main anti-slip pads, and the inner walls of the lower clamp and the upper clamp are all fixedly connected with round tube anti-slip pads.

[0017] By setting the anti-slip pad on the main body when the main body connector is fitted onto the steel beam, the friction between the main body connector and the steel beam is increased, preventing the main body connector from sliding on the steel beam. Similarly, when connecting the round pipe, the anti-slip pad on the round pipe increases the friction between the clamp and the round pipe, making the round pipe connection more stable.

[0018] In a preferred embodiment, reinforcing ribs are fixedly connected at equal intervals between the outer side of the main connector and one side of the side ear.

[0019] By adding reinforcing ribs, the connection strength between the main connecting parts and the side lugs is enhanced, which can effectively disperse and bear various stresses generated during the use of the bridge.

[0020] The prefabricated steel structure connection component provided by this utility model has the following advantages:

[0021] In this utility model, firstly, the two main connecting parts are respectively fitted onto the ends of the two steel beams so that they cooperate with each other. Then, the construction workers pass the first fastening screw through the screw hole on the corresponding side ear and tighten the screw to firmly fix the two main connecting parts together, completing the initial connection of the steel beams and laying the foundation for connecting other structural components through the round tube connecting assembly and the square tube connecting assembly.

[0022] 1. It can meet diverse architectural needs and complex design schemes, providing architects and engineers with greater room for innovation, making architectural shapes more diverse and varied, reducing material waste, and can be applied to various scenarios through different combinations, reducing customization needs, thereby saving costs and resources;

[0023] 2. The connecting components adopt bolt connection, which eliminates the need for complicated welding processes. The installation process is simple and quick, reducing construction difficulty and reliance on professional workers. The main connecting parts made of high-strength steel and the anti-loosening fastening bolts ensure the reliability of the connection and can withstand large loads. Compared with traditional devices, it greatly improves the quality of operation and efficiency of use. Attached Figure Description

[0032] The prefabricated steel structure connection component disclosed in this utility model is mainly used in prefabricated building scenarios.

[0033] Reference Figures 1-6 A prefabricated steel structure connection component includes two main connecting parts 1, a round tube connection component and a square tube connection component. The two main connecting parts 1 are used together. The round tube connection component and the square tube connection component are both set on the corresponding main connecting parts 1. Side ears 2 are fixedly connected to both sides of the main connecting parts 1. The two corresponding side ears 2 are connected to each other by a plurality of first fastening screws 3.

[0034] In this embodiment: First, the two main connecting parts 1 are respectively fitted onto the ends of the two steel beams so that they fit together. Then, the construction workers pass the first fastening screw 3 through the screw hole on the corresponding side ear 2 and tighten the screw to firmly fix the two main connecting parts 1 together, completing the initial connection of the steel beams and laying the foundation for connecting other structural components through the round tube connecting assembly and the square tube connecting assembly.

[0035] In a preferred embodiment, the circular tube connection assembly includes a lower clamp 4, an upper clamp 5, and a second fastening screw 8. The lower clamp 4 is fixedly connected to the top of the corresponding main body connector 1, and the upper clamp 5 is used in conjunction with the lower clamp 4 through a plurality of second fastening screws 8.

[0036] In this embodiment, when it is necessary to connect the circular pipe structure to the installed steel beam, first place one end of the circular pipe on the lower clamp 4, and then cover the circular pipe with the upper clamp 5 to align the two. Subsequently, the construction personnel screw the second fastening screw 8 into the corresponding screw holes of the lower clamp 4 and the upper clamp 5, and gradually tighten them to achieve a stable connection between the circular pipe and the steel beam. For example, this method can be used when building a circular ventilation duct support for a factory building.

[0037] In a preferred embodiment, the square tube connecting assembly includes a square tube connector 6, four limiting screws 7, two support frames 9, and two rotating shafts 10. The two support frames 9 are fixedly connected to the main connector 1, and the two rotating shafts 10 are rotatably connected to the interior of the corresponding support frames 9. The square tube connector 6 is fixedly connected between the two rotating shafts 10, and the four limiting screws 7 symmetrically pass through the interior of the square tube connector 6.

[0038] In this embodiment: When constructing the wall frame of a steel structure factory building, it is necessary to connect the square tube to the steel beam. The construction workers first rotate the square tube connector 6 to adjust its angle so that it matches the installation position of the square tube. Then, one end of the square tube is inserted into the square tube connector 6. By screwing in the limiting screw 7, the end of the limiting screw 7 abuts against the inner wall of the square tube, thereby fixing the square tube in the square tube connector 6 and completing the connection between the square tube and the steel beam.

[0039] In a preferred embodiment, a fixing plate 11 is fixedly connected to each of the two support frames 9 on the side away from each other. The fixing plate 11 is threaded with a limit screw 12 inside. A limit hole 13 is opened on the outer side of the rotating shaft 10. The limit screw 12 is used in conjunction with the corresponding limit hole 13.

[0040] In this embodiment: After adjusting the angle of the square tube connector 6, in order to prevent it from rotating arbitrarily, the construction personnel rotate the limiting screw 12 on the fixing plate 11 so that its end is aligned with and inserted into the limiting hole 13 on the rotating shaft 10. The rotating shaft 10 is locked, and the angle of the square tube connector 6 is fixed, ensuring the stability of the connecting components during the installation of the square tube.

[0041] In a preferred embodiment, the inner wall of the main connector 1 is fixedly connected with a main anti-slip pad 14, and the inner walls of the lower clamp 4 and the upper clamp 5 are fixedly connected with a round tube anti-slip pad 15.

[0042] In this embodiment, when the main connector 1 is fitted onto the steel beam, the main anti-slip pad 14 increases the friction between the main connector 1 and the steel beam, preventing the main connector 1 from sliding on the steel beam. Similarly, when connecting the round pipe, the round pipe anti-slip pad 15 increases the friction between the clamp and the round pipe, making the round pipe connection more stable.

[0043] In a preferred embodiment, reinforcing ribs 16 are fixedly connected at equal intervals between the outer side of the main connector 1 and one side of the side ear 2.

[0044] In this embodiment, the reinforcing rib 16 enhances the connection strength between the main connector 1 and the side lug 2, effectively dispersing and bearing various stresses generated during the use of the bridge.

[0045] Working principle: In use, firstly, the two main connecting parts 1 are connected by the side lugs 2 and the first fastening screws 3 to ensure the stability and integrity of the main connecting parts 1;

[0046] The round tube connection assembly fixes the round tube to the top of the main body connector 1 through the lower clamp 4 and the upper clamp 5. The second fastening screw 8 ensures the tight connection between the lower clamp 4 and the upper clamp 5. The round tube anti-slip pad 15 prevents the round tube from sliding and ensures the firmness of the connection.

[0047] The square tube connecting assembly fixes the square tube connector 6 to the main connecting piece 1 through the support frame 9 and the rotating shaft 10. The limiting screw 7 passes through the square tube connector 6 to ensure the stable connection of the square tube. The limiting screw 12 in the fixing plate 11 works with the limiting hole 13 on the rotating shaft 10 to adjust the angle of the square tube connector 6 and ensure the flexible connection of the square tube.

[0048] The main anti-slip pad 14 prevents the main connector 1 from sliding during the connection process, and the reinforcing rib 16 enhances the connection strength between the main connector 1 and the side ear 2, ensuring the stability and load-bearing capacity of the overall structure;

[0049] The entire assembly achieves efficient connection between round and square tubes through the coordinated work of the main connector 1, the round tube connection assembly, and the square tube connection assembly. It is suitable for the connection of prefabricated steel structures, improving connection efficiency and structural stability.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
