In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0026] The inner and outer corner profiles based on intumescent steel structure fireproof coatings include a first inner and outer corner profile assembly 1 and a second inner and outer corner profile assembly 2. The bottom end of the first inner and outer corner profile assembly 1 is attached to the upper end of the second inner and outer corner profile assembly 2. The first inner and outer corner profile assembly 1 includes a first profile body 11. A diamond plate 12 is fixedly connected to the bottom end of the first profile body 11. A plug post 13 is fixedly connected to the bottom end of the first profile body 11. A tapered hole 14 is formed inside the first profile body 11. A straight hole 15 is formed inside the first profile body 11. A receiving groove 16 is formed at the lower end of the plug post 13. A spring plate 17 is fixedly connected to the inside of the receiving groove 16 formed in the plug post 13. The second inner and outer corner profile assembly 2 includes a second profile body 21. A diamond groove 22 is formed inside the upper end of the second profile body 21. A first column groove 23 is formed inside the upper end of the second profile body 21. A second column groove 24 is formed at the bottom end of the second profile body 21 near the first column groove 23. The top end of the second profile body 21 is attached to the bottom end of the first profile body 11.

[0027] As a further implementation of this solution, tapered holes 14 and straight holes 15 are formed inside both the first inner and outer corner profile assembly 1 and the second inner and outer corner profile assembly 2. The top view dimension of the first profile body 11 is the same as that of the second profile body 21. The vertical plane of the first profile body 11 is flush with the vertical plane of the second profile body 21. This design enables the intumescent fireproof coating to better fill the inside of the inner and outer corner profiles, improves the bonding stability between the coating and the steel structure, and at the same time ensures the uniform distribution of the fireproof coating, enhancing the fireproof performance;

[0028] As a further implementation plan of this solution, the tapered hole 14 is formed in the shape of a cone, and the straight hole 15 is formed in the shape of a cylinder. The tapered hole 14 penetrates through the interior of the first profile body 11, and the straight hole 15 penetrates through the interior of the first profile body 11, ensuring the alignment accuracy of the internal and external corner profiles during installation, reducing installation errors, and improving construction efficiency and the aesthetics of the overall structure;

[0029] As a further implementation plan of this solution, the diamond-shaped groove 22 is formed in the shape of a rhomboid. The angles of two symmetric corners of the diamond-shaped groove 22 in the top view are 45 degrees respectively. The number of each group of the diamond-shaped grooves 22 is two. The diamond-shaped plate 12 is in the shape of a rhomboid. The number of the diamond-shaped plates 12 corresponds one-to-one to the number of the diamond-shaped grooves 22 opened. The size of the diamond-shaped plate 12 is the same as the size of the opened diamond-shaped groove 22. The outer side of the diamond-shaped plate 12 fits with the inner side of the diamond-shaped groove 22 opened in the second profile body 21, enabling the intumescent fireproof coating to form a stable conical structure after solidification. This structure helps to improve the fire resistance of the internal and external corner parts and facilitates the flow and solidification of the coating;

[0030] As a further implementation plan of this solution, the first column groove 23 is formed in the shape of a cylinder, and the second column groove 24 is formed in the shape of a cylinder. The diameter of the second column groove 24 in the top view is larger than that of the first column groove 23. The first column groove 23 communicates with the second column groove 24. The first column groove 23 penetrates through the upper end of the second profile body 21, ensuring the tight fit between the internal and external corner profiles, reducing the gap after installation, improving the integrity of the structure and the protection effect of the fireproof coating, enabling the internal and external corner profiles to pass through the steel structure smoothly during installation, and at the same time ensuring the vertical alignment, improving the installation accuracy and construction quality;

[0031] As a further implementation plan of this solution, the plug post 13 is in the shape of a grooved cylinder, the receiving groove 16 is formed in the shape of a rectangular body, the spring plate 17 is installed inside the receiving groove 16 opened in the plug post 13, the bottom end of the spring plate 17 is flush with the bottom end of the plug post 13, the outer side of the plug post 13 fits with the outer side of the first column groove 23, the lower end of the plug post 13 is inside the second column groove 24, and the spring plate 17 is clamped inside the second column groove 24, ensuring the stability and limiting effect of the internal and external corner profiles during installation, preventing deviation in the horizontal direction, and improving the installation accuracy and structural safety.

[0032] Workflow: When achieving the precise installation of the first internal and external corner profile assembly 1 and the second internal and external corner profile assembly 2, first spray the intumescent fireproof coating on the surface of the steel structure. The intumescent fireproof coating adheres to the steel structure and has a certain viscosity. First, align the second profile body 21 with the corner of the steel structure for installation, press the second profile body 21 against the corner of the steel structure, so that the intumescent fireproof coating enters the internal of the tapered hole 14 and the straight hole 15 opened in the second profile body 21. The straight hole 15 facilitates part of the intumescent fireproof coating to pass through the inside of the second profile body 21, improving the connection stability between the second profile body 21 and the steel structure, and at the same time improving the uniformity between the intumescent fireproof coating and the second profile body 21. The outside of the tapered hole 14 is wide and gradually narrows towards the inside. After the intumescent fireproof coating flows out from the inside of the tapered hole 14 and solidifies, it will form a cone, further improving the connection stability between the second profile body 21 and the steel structure at this time. After the installation of the second internal and external corner profile assembly 2 is completed, continue to install the first internal and external corner profile assembly 1. Align the diamond plate 12 fixed at the bottom of the first profile body 11 with half of the diamond groove 22 opened in the second profile body 21, and press the diamond plate 12 into the diamond groove 22 opened in the second profile body 21. The pressing angle needs to apply force in the direction parallel to the diamond groove 22 and the diamond plate 12. At this time, the diamond plate 12 slides into the diamond groove 22. The settings of the diamond plate 12 and the diamond groove 22 play a role in limiting the installation between the first profile body 11 and the diamond plate 12, preventing the first profile body 11 from deviating horizontally from the diamond plate 12. After the insertion post 13 is aligned with the first column groove 23 opened in the second profile body 21, then move the first profile body 11 downward. After the spring plate 17 contacts the first column groove 23 opened in the second profile body 21, at this time the spring plate 17 deforms and the spring plate 17 is received into the receiving groove 16 opened in the insertion post 13. The insertion post 13 slides in the first column groove 23 opened in the second profile body 21. The settings of the insertion post 13 and the first column groove 23 can ensure that the first profile body 11 is aligned with the vertical plane of the second profile body 21. When the spring plate 17 moves into the second column groove 24, under the action of the springback of the spring plate 17, the spring plate 17 is engaged into the second column groove 24. At this time, the bottom end of the diamond plate 12 fits with the lower end of the diamond groove 22, completing the installation of the first internal and external corner profile assembly 1 and the second internal and external corner profile assembly 2, greatly reducing the gap between the first internal and external corner profile assembly 1 and the second internal and external corner profile assembly 2 after installation, and at the same time preventing the phenomenon of overlap, ensuring the aesthetics after installation, and at the same time ensuring the construction quality.
