[0027] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0028] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0029] An embodiment of the present application provides a building steel structure that is easy to disassemble, including a main board, wherein the main board includes panels in different directions that are integrally formed; it also includes a clamping mechanism that is clamped and connected to the main board and to a circular steel structure, wherein the clamping mechanism includes a first clamping assembly and a second clamping piece, wherein the first clamping assembly holds the panel at any position and in any direction of the main board and is clamped and connected to the main board, wherein the second clamping piece is located in the first clamping assembly, wherein the second clamping piece clamps the circular steel structure and is rotatably connected to the first clamping assembly; and it also includes a fixing assembly that is fitted and connected to the clamping mechanism and locks the clamping mechanism.

[0030] The above-mentioned building steel structure that is easy to disassemble is provided by operating the fixing component to separate it from the clamping mechanism, and then adjusting the position of the first clamping component to separate it from the panel of the main board. At this time, the clamping mechanism can be separated from the main board. Since the clamping mechanism is connected to the circular steel structure, the circular steel structure can also be separated from the main board. The entire disassembly process is simple to operate and improves efficiency.

[0031] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] See also Figure 1-Figure 4 The embodiment of the present application provides a building steel structure 100 that is easy to disassemble, including a main board 10, wherein the main board 10 includes panels in different directions that are integrally formed; it also includes a clamping mechanism 20, which is clamped and connected to the main board 10 and is clamped and connected to a circular steel structure 30, wherein the clamping mechanism 20 includes a first clamping component 21 and a second clamping member 22, wherein the first clamping component 21 holds the panel at any position and in any direction of the main board 10 and is clamped and connected to the main board 10, wherein the second clamping member is located in the first clamping component 21, and the second clamping member 22 clamps the circular steel structure 30 and is rotatably connected to the first clamping component 21; it also includes a fixing component 40, wherein the fixing component 40 is fitted and connected to the clamping mechanism 20 and locks the clamping mechanism 20.

[0033] Specifically, the main board 10 is the basic part of the entire steel structure, which is formed in one piece by panels in different directions. This design makes the main board 10 have higher strength and stability. During the manufacturing process of the main board 10, multiple panels are integrated together in a specific direction and angle through an integrated molding technology to form an integral main board 10 structure. It is suitable for various building structures that require high strength and stability, such as bridges, high-rise buildings, etc.

[0034] Furthermore, the main function of the clamping mechanism 20 is to fix the main board 10 and the circular steel structure 30. It has a first clamping component 21 and a second clamping member 22, which can achieve multi-directional fixation and enhance the stability of the structure. The first clamping component 21 can clamp the panel at any position and in any direction of the main board 10 and realize a clamping connection with the main board 10. The second clamping member 22 is located in the first clamping component 21, and is used to clamp the circular steel structure 30 and realize a rotational connection with the first clamping component 21. It is suitable for scenes where the circular steel structure 30 needs to be fixed, such as large industrial facilities, petrochemical facilities, etc.

[0035] Furthermore, the fixing assembly 40 is used to fix the clamping mechanism 20 on the mainboard 10 and ensure its stability. It can fit tightly with the clamping mechanism 20 and realize the locking function. The fixing member 41 passes through the first clamp 211, the second clamp 22 and the second clamp 212 in sequence and fits and connects with them. The locking member 42 is connected to the fixing member 41 by a thread, and the locking force can be adjusted to ensure the stability and firmness of the clamping mechanism 20.

[0036] Furthermore, the first clamping assembly 21 includes a first clamp 211 and a second clamp 212, which work together to clamp the mainboard 10. This design enables the first clamping assembly 21 to have higher clamping force and stability. The first clamp 211 and the second clamp 212 clamp the mainboard 10 together to generate a first clamping force. The mainboard 10 is located between the first clamp 211 and the second clamp 212, ensuring the stability and firmness of the mainboard 10. It is suitable for scenes where a mainboard 10 fixing device with high strength and stability is required, such as high-rise buildings, large industrial facilities, etc.

[0037] In summary, the second clamping member 22 includes a clamping portion 221 and a connecting portion 222. The clamping portion 221 is used to clamp the circular steel structure 30, while the connecting portion 222 is connected to the first clamping assembly 21. This design enables the second clamping member 22 to have a higher clamping force and stability. During the fixing process, the clamping portion 221 of the second clamping member 22 clamps the circular steel structure 30, while the connecting portion 222 is connected to the first clamping assembly 21, ensuring the stability and firmness of the entire structure. It is suitable for scenarios where the circular steel structure 30 needs to be fixed, such as large industrial facilities, petrochemical facilities, etc.

[0038] In a specific implementation example, the first clamping assembly 21 includes a first clamp 211 and a second clamp 212, the first clamp 211 and the second clamp 212 are connected, the first clamp 211 and the second clamp 212 are facing each other and jointly clamping the mainboard 10 to generate a first clamping force, and the mainboard 10 is located between the first clamp 211 and the second clamp 212.

[0039] Specifically, the two clamps can work as a whole, which enhances the stability of clamping. Through the joint action of the first clamp 211 and the second clamp 212, the mainboard 10 can be effectively fixed, which increases the stability of the structure. The two clamps work together to generate an obvious clamping force, so that the mainboard 10 can be firmly fixed in a predetermined position. It is ensured that the mainboard 10 is completely clamped by the two clamps, leaving no unfixed parts, which enhances the integrity of the structure.

[0040] Furthermore, when the motherboard 10 needs to be fixed, the first clamp 211 and the second clamp 212 are connected together. The connected first clamping assembly 21 is placed on the motherboard 10 to ensure that the motherboard 10 is located between the two clamps. The first clamping assembly 21 is operated to fit tightly with the motherboard 10 and generate sufficient clamping force to fix the motherboard 10.

[0041] Furthermore, this design is applicable to all structures that need to firmly fix the mainboard 10, especially those that need to bear large loads or require high stability, such as large buildings, bridges, high-rise buildings, etc.

[0042] In a specific implementation example, one end of the first clamp 211 and the second clamp 212 that fits the mainboard 10 includes a serration 213 , and the serration 213 fits tightly with the mainboard 10 .

[0043] Specifically, the close fit between the serrations 213 and the mainboard 10 increases the contact area, thereby increasing the clamping force, so that the mainboard 10 can be fixed more firmly.

[0044] Furthermore, the design of the serrations 213 also has an anti-slip effect, which can prevent the mainboard 10 from sliding during the fixing process, thereby ensuring the stability of the fixing. Due to the increase in clamping force and the anti-slip effect, this design improves the safety of the entire structure and reduces the potential risks caused by loose fixing.

[0045] Furthermore, when the first clamp 211 and the second clamp 212 contact and clamp the mainboard 10, the serrations 213 will fit tightly with the mainboard 10. This process is automatic and does not require additional operations. Due to the special design of the serrations 213, it can fit tightly on the mainboard 10 and generate a strong clamping force.

[0046] Furthermore, this design is applicable to all structures that need to firmly fix the main board 10, especially those that need to bear large loads or require high stability, such as large buildings, bridges, high-rise buildings, etc. Due to its anti-slip properties, this design is particularly suitable for structures that may be subject to vibration or shock, such as buildings in earthquake-prone areas.

[0047] In a specific implementation example, the fixing assembly 40 includes: a fixing member 41 and a locking member 42. The fixing member 41 passes through the first clamp 211, the second clamp 22 and the second clamp 212 in sequence and is closely connected; the locking member 42 is threadedly connected to the fixing member 41 and adjusts the locking force.

[0048] Specifically, the fixing member 41 passes through the first clamp 211, the second clamp 22 and the second clamp 212 in sequence and is closely connected therewith, thereby ensuring a stable connection between the various components and enhancing the integrity of the structure.

[0049] Furthermore, since the fixing member 41 can pass through different clamping assemblies in sequence, this design has good adaptability and can be used in conjunction with various clamping assemblies. Through the threaded connection, the locking member 42 can easily adjust the locking force, thereby controlling the clamping force between the clamping assemblies to ensure appropriate fixing strength. The design of the locking member 42 increases the reliability of the entire structure and ensures that a stable fixing effect can be maintained under various working conditions.

[0050] Furthermore, during the assembly process, the fixing member 41 is first passed through the first clamp 211, the second clamp 22 and the second clamp 212 in sequence. Then, the locking member 42 is rotated to be threadedly connected with the fixing member 41, and the locking force is gradually increased, so as to properly fix the clamping assembly.

[0051] In a specific implementation example, the second clamping member 22 includes: a clamping portion 221 and a connecting portion 222. The clamping portion 221 is used to clamp and connect the circular steel structure 30; the connecting portion 222 is integrally formed with the clamping portion 221 and is located between the first clamp 211 and the second clamp 212.

[0052] Specifically, the clamping portion 221 is specially designed to clamp the circular steel structure 30. Through its special arc structure, it can better adapt to the shape of the circular steel structure 30 and improve the stability and reliability of clamping. Since the clamping portion 221 and the connecting portion 222 are integrally formed, such a design simplifies the production process, facilitates installation work, and reduces overall costs.

[0053] Furthermore, the connecting portion 222 is located between the first clamp 211 and the second clamp 212, providing a stable connection point for the fixing member 41, thereby ensuring the stability of the entire structure. The one-piece structural design reduces unnecessary space occupation, makes the entire steel structure more compact, and is conducive to optimizing structural performance.

[0054] Furthermore, during the installation process, the second clamping member 22 first clamps the circular steel structure 30 through its clamping portion 221. Then, the connecting portion 222 is fitted and connected with the first clamp 211 and the second clamp 212 to ensure the stability of the entire clamping mechanism 20. Due to the integrated design of the connecting portion 222 and the clamping portion 221, the installation process becomes very simple.

[0055] In a specific implementation example, the clamping portion 221 is configured as an arc-shaped structure that fits the circular steel structure 30 .

[0056] Specifically, the design of the shaped structure enables the clamping portion 221 to better fit the shape of the circular steel structure 30, and can provide a more stable clamping effect both in the radial direction and in the axial direction.

[0057] Furthermore, the arc structure can adapt to circular steel structures 30 of different sizes and shapes, thereby improving the adaptability of the clamping mechanism 20 to different structures. The design of the arc structure can disperse the clamping force, reduce the possibility of stress concentration, and thus extend the service life of the clamping mechanism 20.

[0058] Furthermore, during the installation process, the clamping portion 221 is tightly fitted with the circular steel structure 30 through its arc structure. As the locking member 42 is adjusted, the clamping force between the clamping portion 221 and the circular steel structure 30 gradually increases, ensuring that the circular steel structure 30 is stably fixed in all directions.

[0059] Furthermore, this design is applicable to various building steel structures that need to fix the circular steel structure 30, especially in large buildings, bridges and elevated structures. Due to its arc-shaped clamping design, this structure can provide stable and reliable fixation, while adapting to various sizes and shapes of circular steel structures 30, simplifying the installation process and improving work efficiency.

[0060] In a specific implementation example, an anti-slip member 2230 is provided on the mating surface between the clamping portion 221 and the circular steel structure 30 .

[0061] Specifically, the anti-slip member 2230 provides additional friction between the fitting surface of the clamping portion 221 and the circular steel structure 30 , ensuring that the circular steel structure 30 can be stably fixed at a desired position under various working conditions.

[0062] Furthermore, with the provision of the anti-slip member 2230, the circular steel structure 30 will not slide in the clamping portion 221 even when subjected to external loads or vibrations, thereby ensuring the stability of the structure. Due to the function of the anti-slip member 2230, when the circular steel structure 30 needs to be disassembled, only the locking member 42 needs to be adjusted to easily remove the circular steel structure 30 from the clamping portion 221, thereby simplifying the disassembly process.

[0063] Furthermore, during the installation process, the clamping portion 221 is tightly fitted with the circular steel structure 30 through its arc structure. As the locking member 42 is adjusted, the clamping force between the clamping portion 221 and the circular steel structure 30 gradually increases. Due to the presence of the anti-slip member 2230, the circular steel structure 30 is firmly fixed in the clamping portion 221 and will not slide. When disassembly is required, the locking member 42 is adjusted to an appropriate position to make the anti-slip member 2230 ineffective, thereby conveniently removing the circular steel structure 30 from the clamping portion 221.

[0064] In a specific implementation example, the connecting portion 222 is provided with a through hole 2221 , through which the fixing member 41 and the second clamping member 22 are closely connected.

[0065] Specifically, the provision of the through hole 2221 simplifies the connection structure between the second clamping member 22 and the fixing member 41, reduces unnecessary parts, and reduces the overall cost. Through the through hole 2221, the fixing member 41 can be quickly and accurately connected to the second clamping member 22, thereby improving the installation efficiency. The cooperation between the through hole 2221 and the fixing member 41 provides a stable connection, thereby ensuring the overall stability of the clamping mechanism 20.

[0066] Furthermore, the fitting connection between the fixing member 41 and the second clamping member 22 increases the clamping force of the clamping mechanism 20 on the main board 10 and the circular steel structure 30, and improves the stability of the overall structure. When the clamping mechanism 20 needs to be disassembled, the fixing member 41 can be easily separated from the second clamping member 22 through the through hole 2221, simplifying the disassembly process.

[0067] Furthermore, during the installation process, the fixing member 41 sequentially passes through the first clamp 211, the second clamp 22, and the second clamp 212. When the fixing member 41 reaches the through hole 2221 of the second clamp 22, the fixing member 41 and the second clamp 22 are tightly fitted by adjusting the locking member 42, and the installation of the entire clamping mechanism 20 is completed. When disassembly is required, the locking member 42 is adjusted, the fixing member 41 is separated from the second clamp 22, and the entire clamping mechanism 20 can be easily disassembled.

[0068] In a specific implementation example, the first clamp 211 is provided with a first fixing hole 2111 corresponding to the through hole 2221, the second clamp 212 is provided with a second fixing hole corresponding to the through hole 2221, and the fixing member 41 passes through the first fixing hole 2111, the through hole 2221 and the second fixing hole in sequence.

[0069] Specifically, the provision of the first fixing hole 2111 enhances the stability between the fixing member 41 and the first clamp 211, and ensures the overall stability of the clamping mechanism 20. The corresponding relationship between the first fixing hole 2111 and the through hole 2221 makes the installation of the fixing member 41 easier and improves the installation efficiency. The design of the first fixing hole 2111 enables the fixing member 41 to adapt to different clamping requirements, and improves the adaptability of the clamping mechanism 20.

[0070] Furthermore, the design of the second fixing hole enhances the clamping force between the fixing member 41 and the second clamp 212, thereby improving the clamping effect. The design of the second fixing hole makes it more convenient to disassemble the fixing member 41, thereby simplifying the disassembly process. Through the second fixing hole, the fixing member 41 can be quickly and accurately connected to the second clamp 22, thereby improving work efficiency.

[0071] Furthermore, the fixing member 41 passes through the first fixing hole 2111, the through hole 2221 and the second fixing hole in sequence, thereby enhancing the connection stability between the fixing member 41 and the clamping mechanism 20. In this way, the fixing member 41 can be quickly and accurately connected to the clamping mechanism 20, thereby improving the installation efficiency. By adjusting the locking member 42, the fixing member 41 can be conveniently locked, thereby ensuring the stability of the clamping mechanism 20.

[0072] Furthermore, during the installation process, the fixing member 41 sequentially passes through the first fixing hole 2111 of the first clamp 211, the through hole 2221 of the second clamp 22, and the second fixing hole of the second clamp 212. By adjusting the locking member 42, the fixing member 41 is tightly fitted with the clamping mechanism 20, and the installation of the entire clamping mechanism 20 is completed. When disassembly is required, the locking member 42 is adjusted, the fixing member 41 is separated from the clamping mechanism 20, and the entire clamping mechanism 20 can be easily disassembled.

[0073] In a specific implementation example, the clamping surfaces of the mainboard 10 and the clamping mechanism 20 are provided with an anti-slip coating.

[0074] Specifically, the anti-slip coating increases the friction between the mainboard 10 and the clamping mechanism 20, ensures the stability of the clamping, and prevents the mainboard 10 from sliding during the clamping process. Due to the presence of the anti-slip coating, the mainboard 10 can be more easily aligned and fixed with the clamping mechanism 20, simplifying the installation process. The anti-slip coating reduces the risk of accidents caused by sliding and improves the safety of the overall structure.

[0075] Furthermore, during the installation process, the mainboard 10 with the anti-skid coating fits tightly with the clamping mechanism 20. Due to the presence of the anti-skid coating, the mainboard 10 can be stably fixed on the clamping mechanism 20 and is not prone to slipping. When disassembly is required, the mainboard 10 can be easily separated from the clamping mechanism 20 by adjusting the locking member 42 or related mechanisms.

[0076] Thus, the above-mentioned easy-to-disassemble building steel structure 100 is provided by operating the fixing component 40 to separate it from the clamping mechanism 20, and then adjusting the position of the first clamping component 21 to separate it from the panel of the main board 10. At this time, the clamping mechanism 20 can be separated from the main board 10. Since the clamping mechanism 20 is connected to the circular steel structure 30, the circular steel structure 30 can also be separated from the main board 10. The entire disassembly process is simple to operate and improves efficiency.

[0077] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
