Description

Technical Field

[0001] This utility model relates to the field of steel structure building construction technology, and more specifically, to a packaging structure for I-shaped steel columns. Background Technology

[0002] Steel structure buildings are a type of building primarily constructed using steel as the main structural material. They offer numerous advantages, including high strength, light weight, good seismic performance, rapid construction, and recyclability. I-beam steel columns play a crucial role in steel structure buildings. As vertical load-bearing components, they effectively support the building's weight, transferring loads from the floors and roof to the foundation, ensuring structural stability. Simultaneously, I-beam steel columns possess significant bending and shear resistance, providing reliable lateral support under horizontal loads such as wind and seismic forces. This enhances the overall rigidity and seismic resistance of the building, providing strong protection for the safe use of steel structure buildings.

[0003] The environment in which I-beam steel columns are installed is challenging. Frequent rain, easy moisture penetration, and the accumulation of dust, along with the continuous attack of harmful gases like sulfur dioxide, all contribute to the column's susceptibility to rust and corrosion, significantly shortening its lifespan. Furthermore, modern architecture demands high aesthetics, and exposed steel columns clash with the overall refined architectural style, noticeably diminishing the visual appeal. In daily use, with frequent pedestrian traffic, the sharp edges and protrusions on the unencased steel columns can easily scratch or injure passersby. Construction or transport tools are also highly likely to collide with them, further damaging the columns.

[0004] For the reasons mentioned above, to prevent corrosion, extend the lifespan of the steel columns, match the architectural style and enhance aesthetics, and ensure the safety of personnel and the steel columns themselves, it is imperative to encase the I-beam steel columns after installation. Under current technological conditions, the encasement structure typically relies on two encasing members to surround the steel column. First, locking bolts are used to connect the encasing members to the I-beam steel column, followed by welding for further reinforcement. Finally, decorative panels are installed on the outside of the encasing members. This process involves drilling and welding into the I-beam steel column, which is not only cumbersome, increasing construction time and labor costs, but may also leave weak points such as holes in the steel column, affecting its structural strength. Furthermore, welding defects are prone to occur during the welding process, further reducing the reliability of the encasement structure. Utility Model Content

[0012] Furthermore, based on the aforementioned scheme, both the U-shaped clip and the keel are arranged along the axial direction of the I-shaped steel column.

[0013] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0014] The I-beam steel column packaging structure of this application has significant advantages compared to traditional packaging structures.

[0019] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0020] Please refer to Figure 1 and Figure 2This application provides a packaging structure for an I-beam steel column 100. The I-beam steel column 100 includes a web 101 and two flanges 102. The packaging structure includes a connecting unit, comprising a keel 400 and a U-shaped clip 500. The keel 400 is disposed inside the U-shaped clip 500 and contacts one of the inner surfaces of the U-shaped clip 500. The keel 400 and the other inner surface of the U-shaped clip 500 form a mounting groove for inserting into one end of the flange 102. When the mounting groove is adapted to the flange 102, the keel 400 is positioned... On the side of the aforementioned flange plate 102 away from the aforementioned web plate 101; wherein, the number of the aforementioned connecting units is four, and each of the four ends of the two aforementioned flange plates 102 is adapted to one-to-one; an annular fireproof plate 200 for simultaneously fitting onto the aforementioned I-shaped steel column 100 and any of the aforementioned connecting units, wherein it is provided with connecting nails 600 for simultaneously connecting the U-shaped clip 500 and the keel 400 of one of the aforementioned connecting units; wherein, the number of the aforementioned connecting nails 600 is four, and each of the four aforementioned connecting units is adapted to one-to-one; and a decorative panel 300 covering the outer ring surface of the aforementioned annular fireproof plate 200.

[0021] The I-beam steel column 100 packaging structure of this application has significant advantages compared with traditional packaging structures. In its packaging structure, the connecting unit consists of a keel 400 placed inside a U-shaped clamp 500, forming an installation slot that is inserted into the end of the flange plate 102. Then, connecting nails 600 connect the U-shaped clamp and the keel 400, thus achieving the connection between the annular fireproof plate 200 and the I-beam steel column 100. In this process, there is no need to drill holes in the I-beam steel column 100, effectively preventing damage to the steel column structure's strength due to drilling, ensuring the complete preservation of the steel column's mechanical properties, and providing higher safety and reliability in subsequent use. Furthermore, the entire packaging structure eliminates welding, reducing the potential risk of fire caused by welding, avoiding the adverse effects of welding deformation on packaging accuracy, and effectively reducing construction difficulty, thereby significantly improving construction efficiency.

[0022] Understandably, traditional packaging structures involve installing fireproof and decorative structures on the outside of the covering components after installation. However, this application differs from traditional packaging structures, as it not only eliminates the need for drilling holes in the I-beam steel column 100 but also eliminates the need for welding, thus ensuring construction efficiency.

[0023] In a preferred embodiment, the number of connecting pins 600 in any of the above-mentioned connecting units is two.

[0024] In the above embodiments, the two connecting studs 600 further ensure the stability of the connection between the connecting unit and the annular fireproof plate 200. It should be emphasized that setting the number of connecting studs 600 to two is merely a preferred option presented in this embodiment, and does not constitute a rigid constraint on the actual number of connecting studs 600 that can be used. In different application scenarios or other embodiments, the number of connecting studs 600 can be flexibly adjusted according to specific needs, selecting other suitable values ​​to better adapt to diverse usage conditions and ensure that the overall performance of the packaging structure reaches its optimal level.

[0025] As a preferred embodiment, the aforementioned connecting pin 600 is a self-tapping pin.

[0026] In the above embodiments, self-tapping screws do not require pre-drilling during installation. They can be directly screwed into the U-shaped clips, keel 400, and annular fireproof plate 200 of the connecting unit by their sharp threaded parts. This not only simplifies the installation process and greatly saves the time spent on pre-drilling preparation, but also avoids the risk of material damage that may be caused by drilling operations, ensuring the integrity of each component structure.

[0027] In a preferred embodiment, an adhesive layer 700 is provided between the annular fireproof board 200 and the decorative panel 300.

[0028] In the above embodiments, the adhesive layer 700 between the annular fireproof board 200 and the decorative panel 300 offers several advantages. First, the adhesive layer 700 enables a seamless fit between the annular fireproof board 200 and the decorative panel 300. Compared to traditional mechanical connections, this avoids potential aesthetic defects caused by exposed connectors, resulting in a smoother and more aesthetically pleasing appearance for the entire I-beam steel column 100 packaging structure, thus enhancing the visual effect. Second, the adhesive layer 700 simplifies the installation process, eliminating the need for complex fastener installations, reducing labor and time costs, significantly improving construction efficiency, and also lowering the risk of malfunctions caused by excessive connectors, bringing numerous conveniences to the protection and decoration of the steel column.

[0029] As a preferred embodiment, the U-shaped clip 500 is made of stainless steel.

[0030] In the above embodiments, the use of stainless steel U-shaped fasteners offers significant advantages. Firstly, stainless steel possesses excellent corrosion resistance. Whether in humid outdoor environments or facing potential rain erosion and chemical contamination, the U-shaped fasteners maintain structural stability and are not easily rusted or corroded. This ensures the long-term reliability of the connecting unit and the entire I-beam steel column 100 packaging structure, greatly extending its service life. Secondly, stainless steel has high strength and good toughness. When subjected to external impact, the U-shaped fasteners firmly fix the keel 400, maintaining the tightness of the insertion fit between the mounting slot and the end of the flange plate 102, effectively preventing components from loosening or falling off, and ensuring the stability of the packaging structure.

[0031] In a preferred embodiment, both the U-shaped clip 500 and the keel 400 are arranged along the axial direction of the I-shaped steel column 100.

[0032] In the above embodiment, the axial arrangement of the U-shaped clamp 500 and the aforementioned keel 400 allows for a more precise and stable fit between the connecting unit and the I-beam steel column 100. The U-shaped clamp is tightly inserted into the end of the flange plate 102 along the axis, and the keel 400 also fits in, ensuring uniform and reasonable force transmission. This allows the entire packaging structure to work together effectively when bearing the weight of the steel column itself and potential external impacts, greatly enhancing the stability of the structure and effectively avoiding problems such as loosening and deformation caused by uneven force distribution. Secondly, in terms of installation convenience, operators only need to install the U-shaped clamp and keel 400 sequentially along the axis of the steel column. The operation process is clear and simple, reducing the adjustment and calibration steps during installation, greatly improving construction efficiency and reducing labor costs.
