Detailed implementation manners

[0036] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0037] Embodiment: As Figures 1 to 4As shown, the prefabricated square steel column wall base component is installed between the steel column 5 and the decorative panel 6. Its main purpose is to prevent damage to the fireproof coating on the surface of the steel column 5 and ensure the flatness of the decorative panel 6 during installation. This component mainly consists of a W-shaped square column connector 1 and a leveling support 2. Specifically, the above-mentioned W-shaped square column connector 1 includes a first fitting part 1-2 and a second fitting part 1-3 that fit the surface of the above-mentioned steel column 5. The angle at the connection between the first fitting part 1-2 and the second fitting part 1-3 is adapted to the external angle of the above-mentioned steel column 5. That is, if the external angle of the steel column 5 is a right angle, the first fitting part 1-2 and the second fitting part 1-3 are arranged perpendicular to each other, so that while the first fitting part 1-2 and the second fitting part 1-3 completely fit the steel column 5, they wrap the external angle of the steel column 5, ensuring the stability of the W-shaped square column connector for subsequent installation of the decorative panel 6. The W-shaped square column connector 1 in this embodiment further includes a first connecting part 1-1 and a second connecting part 1-4, and fastening holes 1-5 are provided in both the first connecting part 1-1 and the second connecting part 1-4. The above-mentioned leveling support 2 includes a decorative panel fitting part 2-1 and a support connecting part 2-3 with fastening holes 2-7. The decorative panel fitting part 2-1 is the part that fits the inner surface of the decorative panel 6, and the support connecting part 2-3 is the part that connects to the first connecting part 1-1 and the second connecting part 1-4 in the W-shaped square column connector 1. To ensure the stability of the connection, there are two of the above-mentioned support connecting parts 2-3 in this embodiment, and the two support connecting parts 2-3 are arranged at intervals. During installation, the fastening holes 1-5 and the fastening holes 2-7 are arranged corresponding to each other, and the connection between the W-shaped square column connector 1 and the leveling support 2 is realized by passing a fastener 3 through the fastening holes 1-5 and the fastening holes 2-7. The fastener 3 can be a locking bolt with a simple structure and high economic practicality.

[0038] To ensure the overall structural strength of the W-shaped square column connector 1, reduce the probability of the first connecting part 1-1 and the second connecting part 1-4 breaking due to external forces, and facilitate passing the locking part through the fastening hole 1-5 to achieve the purpose of connecting two W-shaped square column connectors 1 together, the first connecting part 1-1 and the first fitting part 1-2, and the second connecting part 1-4 and the second fitting part 1-3 are arranged perpendicular to each other, and the perpendicular arrangement is convenient for manufacturing.

[0039] The above-mentioned connecting part 1-1, the above-mentioned connecting part 1-4, the above-mentioned fitting part 1-2 and the above-mentioned fitting part 1-3 are all arranged in a plate shape, and sheet metal parts with simple structures can be used. The sheet metal parts need to maintain the same thickness everywhere to ensure the flatness of their surfaces. Further, in order to reduce the manufacturing difficulty and the later installation difficulty, and standardize the W-shaped square column connector 1, and since the cross-section of the steel column 5 is usually square, the above-mentioned fitting part 1-2 and the above-mentioned fitting part 1-3 can be set to be of equal length. Then, only four W-shaped square column connectors 1 need to be installed around the steel column 5, and they are installed around the steel column 5 in a way similar to a hoop. Compared with the wet method technology in the prior art, it can reduce the damage to the fireproof coating on the surface of the steel column 5.

[0040] A connector fitting part 2-2 is vertically provided at the bottom of the above-mentioned support part connecting part 2-3. The above-mentioned connector fitting part 2-2 is fitted with the above-mentioned fitting part 1-2 and the above-mentioned fitting part 1-3, which increases the contact area between the W-shaped square column connector 1 and the leveling support 2, and further ensures the tightness at the connection between the two, thereby ensuring the installation effect of the assembled square steel column wall base component. In order to ensure the flatness of the decorative panel 6 during the installation process, the above-mentioned leveling support 2 needs to ensure the flatness of the surfaces of the decorative panel fitting part 2-1 and the connector fitting part 2-2 during the manufacturing process.

[0041] In order to prevent the decorative panel 6 from tilting during the installation process, and at the same time to ensure the overall structural strength of the leveling support 2, the above-mentioned support part connecting part 2-3 is perpendicularly arranged with the above-mentioned decorative panel fitting part 2-1 and the above-mentioned connector fitting part 2-2, then the above-mentioned decorative panel fitting part 2-1 and the above-mentioned connector fitting part 2-2 are arranged parallel to each other. If the above-mentioned support part connecting part 2-3 is arranged obliquely with the above-mentioned decorative panel fitting part 2-1 and the above-mentioned connector fitting part 2-2, the above-mentioned support part connecting part 2-3 is extremely likely to break under the action of external forces, affecting the service life of the leveling support.

[0042] The gaps between the above-mentioned decorative panel fitting part 2-1 and the decorative panel 6 and between the above-mentioned connector fitting part 2-2 and the steel column 5 can be filled with glue to ensure the fitting degree between the above-mentioned decorative panel fitting part 2-1 and the decorative panel 6 and between the above-mentioned connector fitting part 2-2 and the steel column 5. Or a glue groove 2-4 is formed on the surface of the above-mentioned decorative panel fitting part 2-1, and the connection between the leveling support 2 and the decorative panel 6 is realized by pasting 3M glue 4 in the glue groove 2-4. In order to reduce the use of 3M glue 4 and at the same time ensure the firmness between the leveling support 2 and the decorative panel 6, there are two above-mentioned glue grooves 2-4 in this embodiment, and the two above-mentioned glue grooves 2-4 are symmetrically arranged along the central axis of the above-mentioned decorative panel fitting part 2-1.

[0043] The above leveling support 2 is integrally formed, which can avoid the generation of gaps at the joints between the support connecting part 2-3, the decorative panel fitting part 2-1, and the connecting piece fitting part 2-2, thereby avoiding fracture caused by stress concentration, ensuring the structural strength of the leveling support, and the integrally injection-molded method makes the production of the leveling support convenient and can greatly improve the production efficiency.

[0044] The corners of the above leveling support 2 are rounded. Compared with right angles, it can effectively improve the safety of operators during the installation process, and at the same time increase the overall aesthetics of the leveling support 2 and improve the quality of the above leveling support.

[0045] To avoid interference between two adjacent W-shaped square column connectors 1 during installation, the lengths of the above fitting part one 1-2 and the above fitting part two 1-3 are less than half of the bottom side length of the above steel column 5. When two W-shaped square column connectors 1 are installed around the steel column 5, there is a gap between the above connecting part one 1-1 and the above connecting part two 1-4, and the size of this gap is the distance between two support connecting parts 2-3 minus the thicknesses of the above connecting part one 1-1 and the above connecting part two 1-4, so as to clamp the leveling support 2 outside two adjacent W-shaped square column connectors 1. Then, by passing fasteners 3 such as locking bolts through the first fastening hole 1-5 and the second fastening hole 2-7, and tightening the locking bolts, the connection between the W-shaped square column connector 1 and the leveling support 2 is realized, and the W-shaped square column connector 1 is clamped around the outer surface of the steel column 5.

[0046] To make the steel structure wall have a sound insulation effect, sound insulation materials can be filled between the steel column 5 and the decorative panel 6. To make the distance between the decorative panel 6 and the steel column 5 adjustable to improve the space utilization rate, the above first fastening hole 1-5 and the above second fastening hole 2-7 are both waist-shaped holes. By adjusting the positions of the locking bolts in the above first fastening hole 1-5 and the above second fastening hole 2-7, the distance between the decorative panel fitting part 2-1 and the surface of the steel column 5 is changed to facilitate the filling of substances such as sound insulation materials.

[0047] The above W-shaped square column connector 1 is integrally injection-molded, which can avoid the generation of gaps at the joints between the connecting part one 1-1 and the fitting part one 1-2, between the connecting part two 1-4 and the fitting part two 1-3, and between the fitting part one 1-2 and the fitting part two 1-3, thereby avoiding fracture caused by stress concentration, ensuring the structural strength of the W-shaped square column connector, and the integrally injection-molded method makes the production of the W-shaped square column connector convenient and can greatly improve the production efficiency.

[0048] The corners of the above W-shaped square column connector 1 are rounded. Compared with right angles, it can effectively improve the safety of operators during the installation process, and at the same time increase the overall aesthetics of the W-shaped square column connector 1 and improve the quality of the above W-shaped square column connector.

[0049] In order to further enhance the overall aesthetic appearance of the W-shaped square column connector 1, the W-shaped square column connector 1 in this embodiment is designed as an axisymmetric body, that is, the first connecting part 1-1 and the second connecting part 1-4 are set to be of equal length, and the first fitting part 1-2 and the second fitting part 1-3 are set to be of equal length.
