Detailed implementation manners

[0040] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] Example 1: As Figures 1 to 7 shown, the prefabricated square steel column wall finishing system includes a steel column 5 and a decorative panel 6. A wall base connection assembly is installed between the steel column 5 and the decorative panel 6, mainly to prevent damage to the fireproof coating on the surface of the steel column 5, and at the same time ensure the flatness of the decorative panel 6 during the installation process and improve the installation speed of the decorative panel 6. The two ends of the decorative panel 6 are chamfered at 45 degrees to form a docking portion 6-3 at a 45-degree angle, and an installation groove 6-1 with a long strip-shaped cross-section is opened along the docking portion 6-3 and extends towards the center position of the decorative panel 6. The two installation grooves 6-1 of two adjacent decorative panels 6 are assembled to form an L-shaped groove 6-2. The adjacent two decorative panels 6 are quickly connected by installing an L-shaped connector 7 in the L-shaped groove 6-2.

[0042] Specifically, the L-shaped connector 7 in this embodiment includes a first connecting portion 7-1 and a second connecting portion 7-2. By fitting the first connecting portion 7-1 into one of the adjacent installation grooves 6-1 and fitting the second connecting portion 7-2 into the other adjacent installation groove 6-1, during this process, fixing parts such as screws and pneumatic nails are not required, which can effectively improve the installation efficiency and does not damage the decorative panel 5 and the L-shaped connector 7, enabling them to be reused and avoiding waste of resources and energy. In order to ensure the structural strength at the connection between the first connecting portion 7-1 and the second connecting portion 7-2 and reduce the probability of fracture at their connection, the L-shaped connector 7 can be integrally injection-molded as a whole, while ensuring the tightness at the splicing of adjacent decorative panels 5.

[0043] In order to achieve quick disassembly and assembly, reduce the contact area between the above-mentioned first connecting portion 7-1, the above-mentioned second connecting portion 7-2 and the above-mentioned installation groove 6-1, reduce the frictional force during the installation process, and then reduce the resistance, a plurality of protrusions 7-3 are formed on the inner surfaces of the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2. Similarly, in order to reduce the contact area between the other surfaces of the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2 and the above-mentioned installation groove 6-1, a plurality of protrusions 7-3 are formed on the outer surfaces of the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2, and the protrusions 7-3 are provided protruding from the surfaces of the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2. In order to facilitate installation and at the same time ensure the overall aesthetics of the L-shaped connector 7, the above-mentioned protrusions 7-3 on the inner surface of the first connecting portion 7-1 are symmetrically arranged along the central axis of the first connecting portion 7-1 with the above-mentioned protrusions 7-3 on the outer surface of the first connecting portion 7-1, and the above-mentioned protrusions 7-3 on the inner surface of the second connecting portion 7-2 are symmetrically arranged along the central axis of the second connecting portion 7-2 with the above-mentioned protrusions 7-3 on the outer surface of the second connecting portion 7-2.

[0044] In this embodiment, the cross-section of the above-mentioned protrusion 7-3 is semicircular, and the top of the protrusion 7-3 contacts the installation groove 6-1. Compared with the L-shaped connector 7 with a flat surface, while realizing the function of connecting two decorative panels 5, the installation rate can be greatly improved, the labor intensity of the operator can be reduced, which is beneficial to the popularization and application of the above-mentioned L-shaped connector 7 in the field of decoration technology.

[0045] In order to reduce the manufacturing difficulty and simplify the manufacturing mold, etc., the adjacent two above-mentioned protrusions 7-3 on the above-mentioned first connecting portion 7-1 or the above-mentioned second connecting portion 7-2 are arranged at equal intervals.

[0046] The connection between the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2 is a smooth right angle, that is, no protrusion 7-3 is provided at the connection, so that the connection between the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2 is adapted to the above-mentioned L-shaped groove 6-2, or in other words, the connection between the above-mentioned first connecting portion 7-1 and the above-mentioned second connecting portion 7-2 is arranged to fit the right angle of the above-mentioned L-shaped groove 6-2 to ensure the flatness of the joint of the two decorative panels 5.

[0047] In order to prevent the L-shaped connector 7 from sliding up and down in the L-shaped groove 6-2, the above-mentioned protrusion 7-3 can be abutted against the surface of the above-mentioned installation groove 6-1, that is, the L-shaped connector 7 provides a certain pressure in the direction of the L-shaped groove 6-2 to ensure the stability of the L-shaped connector 7 during the installation process.

[0048] A caulking groove 7-4 is formed between two adjacent protrusions 7-3 in this embodiment. By caulking in the caulking groove 7-4, the tightness at the connection between the L-shaped connector 7 and the decorative panel 5 is ensured, thereby ensuring the structural strength of the connection and the installation quality of the decorative panel 5.

[0049] The wall base connection assembly in this embodiment mainly consists of a W-shaped square column connector 1 and a leveling support 2. Specifically, the W-shaped square column connector 1 includes a first fitting portion 1-2 and a second fitting portion 1-3 that are in contact with the surface of the steel column 5. The angle at the connection between the first fitting portion 1-2 and the second fitting portion 1-3 is adapted to the external angle of the steel column 5. That is, if the external angle of the steel column 5 is a right angle, the first fitting portion 1-2 and the second fitting portion 1-3 are arranged perpendicular to each other, so that while the first fitting portion 1-2 and the second fitting portion 1-3 are completely in contact with the steel column 5, they wrap around 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 also includes a first connecting portion 1-1 and a second connecting portion 1-4, and fastening holes 1-5 are provided in both the first connecting portion 1-1 and the second connecting portion 1-4. The leveling support 2 includes a decorative panel fitting portion 2-1 and a support connecting portion 2-3 with a fastening hole 2-7. The decorative panel fitting portion 2-1 is the part that is in contact with the inner surface of the decorative panel 6, and the support connecting portion 2-3 is the part that is connected to the first connecting portion 1-1 and the second connecting portion 1-4 in the W-shaped square column connector 1. To ensure the stability of the connection, there are two support connecting portions 2-3 in this embodiment, and the two support connecting portions 2-3 are arranged at an interval. During installation, the fastening holes 1-5 and the fastening holes 2-7 are arranged corresponding to each other, and the W-shaped square column connector 1 and the leveling support 2 are connected 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.

[0050] To ensure the overall structural strength of the W-shaped square column connector 1, reduce the probability of the first connecting portion 1-1 and the second connecting portion 1-4 breaking due to external forces, and at the same time facilitate passing the locking member through the fastening hole 1-5 to achieve the purpose of connecting two W-shaped square column connectors 1 together, the first connecting portion 1-1 and the first fitting portion 1-2, and the second connecting portion 1-4 and the second fitting portion 1-3 are arranged perpendicular to each other, and the perpendicular arrangement is convenient for manufacturing.

[0051] 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.

[0052] 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, increasing the contact area between the W-shaped square column connector 1 and the leveling support 2, and further ensuring the tightness at the connection of the two, thereby ensuring the installation effect of the assembled square steel column wall facing system. In order to ensure the flatness of the facing panel 6 during the installation process, the above-mentioned leveling support 2 needs to ensure the flatness of the surface of the facing panel fitting part 2-1 and the connector fitting part 2-2 during the manufacturing process.

[0053] In order to prevent the facing 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 facing panel fitting part 2-1 and the above-mentioned connector fitting part 2-2, then the above-mentioned facing 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 facing 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.

[0054] The gaps between the above-mentioned facing panel fitting part 2-1 and the facing panel 6 and between the above-mentioned connector fitting part 2-2 and the steel column 5 can be injected with glue to ensure the fitting degree between the above-mentioned facing panel fitting part 2-1 and the facing 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 facing panel fitting part 2-1, and the connection between the leveling support 2 and the facing 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 facing panel 6, there are two of the 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 facing panel fitting part 2-1.

[0055] 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 part 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.

[0056] The corners of the above leveling support 2 are rounded. Compared with right angles, it can effectively improve the safety of operators during installation, and at the same time increase the overall aesthetic appearance of the leveling support 2, improving the quality of the above leveling support.

[0057] 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 such as locking bolts 3 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.

[0058] 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, so as to fill substances such as sound insulation materials.

[0059] 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, the joints between the connecting part two 1-4 and the fitting part two 1-3, and the joints 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.

[0060] The corners of the above-mentioned W-shaped square column connector 1 are rounded. Compared with right angles, it can effectively improve the safety of operators during installation. At the same time, it increases the overall aesthetic appearance of the W-shaped square column connector 1 and improves the quality of the above-mentioned W-shaped square column connector. 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.

[0061] As Figures 8 to 15 shown, the installation method of the prefabricated square steel column wall facing system is used to install the prefabricated square steel column wall facing system; it includes the following installation steps:

[0062] a. Pre-assembly: First, pre-fix two W-shaped square column connectors 1 and a leveling support 2 together with locking bolts;

[0063] b. Repeat the installation step a three times to complete the assembly of the square steel column wall base component;

[0064] c. Complete the line marking and positioning on the steel column 5;

[0065] d. Install the pre-assembled square steel column wall base component onto the steel column 5, and adjust the position to the line marking and positioning point, then lock the fastener 3 to fasten the square steel column wall base component on the surface of the steel column 5;

[0066] e. Complete the installation of the square steel column wall base component on the steel column 5, adjust all the leveling supports 2 to complete the leveling of the base;

[0067] f. Paste 3M tape on the wall base connection component, that is, paste 3M tape in the glue groove 2-4, then paste the facing panel 6, and finally insert the L-shaped connector 7 into the 45-degree bevel cutting card slot, that is, the installation slot 6-1, and then sequentially install the facing panels 6 on the remaining surfaces of the steel column 5;

[0068] g. Apply nail-free glue at the L-shaped connector 7, and then install the last facing panel 6 to complete the installation of all the facing panels 6.

[0069] In the above method, by using the L-shaped connector 7 and the wall base connection component, the rapid assembly of the facing panel 6 can be realized, and at the same time, the damage to the fireproof coating on the surface of the steel column can be effectively avoided.

[0070] Embodiment 2: The feature that differentiates this embodiment from Embodiment 1 is that in the prefabricated square steel column wall facing system of this embodiment, in order to reduce the weight of the W-shaped square column connector 1 itself and facilitate the installation of the W-shaped square column connector 1 by the operator, hollow slots 1-6 are provided at the above-mentioned fitting part 1-2 and the above-mentioned fitting part 1-3. The hollow slot 1-6 is a through slot, which can also save production materials and reduce production costs, and is conducive to the popularization and application of the above-mentioned W-shaped square column connector in the market. The shape of the hollow slot 1-6 can be circular, rectangular or any other shape, which is not limited herein.

[0071] Embodiment 3: The feature that differentiates this embodiment from Embodiment 1 is that in the prefabricated square steel column wall facing system of this embodiment, in order to reduce the weight of the leveling support 2 itself and facilitate the installation of the leveling support 2, a first hollow slot 2-5 is provided at the above-mentioned facing panel fitting part 2-1 between the two above-mentioned glue grooves 2-4. Since the area between the two above-mentioned glue grooves 2-4 is relatively large, in order to prevent the first hollow slot 2-5 from being too large and affecting the structural strength and quality of the leveling support, a plurality of the first hollow slots 2-5 are provided at this location, and the plurality of first hollow slots 2-5 are arranged at intervals. The shape of the first hollow slot 2-5 can be circular, rectangular or any other shape, which is not limited herein.

[0072] In order to further reduce the weight of the leveling support itself and facilitate the installation of the leveling support, a second hollow slot 2-6 is provided at the above-mentioned facing panel fitting part 2-1 outside the above-mentioned glue groove 2-4. Similarly, the shape of the second hollow slot 2-6 can be circular, rectangular or any other shape, which is not limited herein.

[0073] Embodiment 4: The feature that differentiates this embodiment from Embodiment 1 is that in the L-shaped connector 7 of this embodiment, the cross-sectional shape of the protrusion 7-3 can be square (not shown in the figure). The top of the protrusion 7-3 is arranged in contact with the surface of the installation groove 6-1. Similarly, the connection between two adjacent facing panels 5 can be realized, ensuring the installation effect and the installation rate at the same time. If the cross-sectional shape of the protrusion 7-3 is square, the cross-section of the caulking groove 7-4 is also square.
