[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] See also Figure 1 The present embodiment provides a non-welded adjustable connection device for a steel pipe column and a method of use, comprising a first side plate, a second side plate and a middle plate, wherein the first side plate and the second side plate are connected via the middle plate, the first side plate and the second side plate are respectively fitted with two sides of the steel pipe column, the first side plate, the second side plate and the middle plate form a first hoop structure, the first hoop structure is connected to the steel pipe column as a whole, wherein the first side plate and the second side plate are respectively tightly fitted on both sides of the steel pipe column to ensure the stability and sealing of the connection, the function of the hoop structure is to tightly surround the steel pipe column, thereby firmly connecting the connection device and the steel pipe column as a whole, this connection method is not only firm, but also easy to adjust, and the steel pipe column can be adjusted or replaced when necessary.

[0029] In the existing building structure construction, steel pipe columns are important load-bearing and supporting structures. The stability and reliability of their connection methods are directly related to the safety and quality of the entire project. At present, the connection devices used for steel pipe columns usually adopt welding. The welding connection can effectively reduce the gap at the connection, increase the overall stability of the structure, and resist the stress caused by the external environment, so that the connection strength is relatively high. However, there are also some problems when the connection devices used for steel pipe columns adopt welding: under certain specific conditions, such as small construction space, strict requirements on structural deformation control or frequent disassembly and reorganization, during the welding process, due to uneven heat input, the local temperature of the structure will rise and thermal stress and thermal deformation will be generated. In a small space, this unevenness may be aggravated because the heat is not easy to dissipate, thereby increasing the risk of welding deformation.

[0030] In order to solve the above problems, in this embodiment, a first clamp structure is formed by the coordinated use of the first side plate, the second side plate and the middle plate. This structure can be firmly attached to both sides of the steel pipe column. In this way, the connecting device not only realizes an integrated connection with the steel pipe column, but also due to its adjustability, can adapt to steel pipe columns of different diameters, thereby increasing its applicability and flexibility. This non-welded adjustable connecting device replaces welding with mechanical fixation, which effectively solves the problems of uneven heat input, local temperature rise, thermal stress and thermal deformation, and welding in a small space that may occur during the welding process, and provides a safer, more efficient and reliable solution for the connection of steel pipe columns.

[0031] Since the steel tube column usually plays a supporting role in the building structure, its stability is directly related to the safety of the entire structure. If the column is not tightly fixed, it may cause structural instability and increase the risk of accidents. In order to solve this problem, in one embodiment, the first side panel and the second side panel are respectively provided with a plurality of first curved panels 1 and second curved panels 2, and the plurality of first curved panels 1 and second curved panels 2 are centrally symmetrical. Every two centrally symmetrical first curved panels 1 and second curved panels 2 constitute a second hoop structure. The steel tube column is located at the center of the second hoop structure. The second hoop structure adjusts the size of the second hoop structure through a connecting piece so that the second hoop structure is fastened to the steel tube column as a whole. Since the steel tube column is generally circular, the first curved panel 1 and the second curved panel 2 can adapt to the shape of the steel tube column to better fix the steel tube column. By setting the second hoop structure composed of the first curved panel 1 and the second curved panel 2, the circular steel tube column can be more tightly fixed, thereby significantly enhancing the overall stability of the structure. The design of the first curved panel 1 and the second curved panel 2 enables it to adapt to the shape of the circular steel tube column, which can ensure that the column is evenly and firmly fixed, reducing the gap or instability caused by shape mismatch. The size of the second hoop structure can be adjusted by the connecting piece to adapt to steel tube columns of different diameters, making the structure more applicable and flexible.

[0032] In order to further facilitate disassembly and replacement and reduce maintenance costs, in one embodiment, the connecting member includes a flange 3 respectively arranged on the outside of the first curved panel 1 and the second curved panel 2 and bolts evenly distributed around the flange 3. The first curved panel 1 and the second curved panel 2 cooperate with the flange 3 and the bolts to form a second clamp structure. The first curved panel 1 and the second curved panel 2 are respectively provided with protrusions, and the outer wall of the steel pipe column is provided with a groove matching the protrusion. Due to the cooperation of the flange 3 and the bolts, the connection between the first curved panel 1 and the second curved panel 2 can be easily adjusted to adapt to steel pipe columns of different sizes or shapes, thereby improving the versatility and adaptability of the connecting device. This non-welding connection method avoids the damage to the material caused by the heat that may be generated during the welding process, and also simplifies the installation process, reduces labor intensity and maintenance costs, and the cooperation between the protrusion and the groove increases the bite between the connecting structure, thereby improving the stability of the connection and reducing the loose connection caused by vibration and other reasons.

[0033] In order to better adapt to the deformation of the steel pipe column, avoid stress concentration caused by deformation, and thus extend the service life of the structure, in one embodiment, positioning holes and arc-shaped waist holes are provided on the second side plate and the middle plate, and adjustment bolts 4 for adjusting the angle between the first clamp structure and the second clamp structure are provided in the positioning holes and the arc-shaped waist holes. The connecting parts and the adjusting bolts 4 are made of high-strength materials. In addition, the middle plate is also connected to the first side plate and the second side plate by bolts. All non-welded connecting parts of the present application are made of high-strength materials. The positioning holes and arc-shaped waist holes in the design allow the adjusting bolts 4 to be adjusted therein, so that the first clamp structure and the second clamp structure can be easily changed. The angle between the hoop structures can adapt to different installation environments and needs. The connectors and adjusting bolts 4 made of high-strength materials can withstand greater loads and improve the stability and safety of the entire structure. The setting of the adjusting bolts 4 allows the connecting device to be quickly adjusted during installation, reducing the difficulty and time of installation. At the same time, maintenance and replacement are also more convenient. Since the connecting device can adjust the angle, the device can be applied to steel pipe columns of various specifications and types, improving its versatility and adaptability. In addition, the design of the arc-shaped waist hole enables the connecting device to better adapt to the deformation of the steel pipe column when subjected to external force, avoiding stress concentration caused by deformation, thereby extending the service life of the structure.

[0034] In addition, a connecting plate 6 is provided between the flange 3 and the first curved surface panel 1 and the second curved surface panel 2, and the stability is further enhanced by the connecting plate 6. Ribbed plates 5 are provided between the two ends of the connecting plate 6 and the flange 3, and between the first curved surface panel 1 and the second curved surface panel 2. The adjusting bolts 4 are provided on the ribbed plates 5. Figure 1 As shown, this design enhances stability and facilitates adjustment of the adjusting bolt 4.

[0035] A method for using a non-welded adjustable connection device for a steel pipe column, comprising the following steps:

[0036] S1: Preparation work, ensure that the surface of the steel pipe column is clean, free of oil, rust and other debris, prepare the corresponding connection device components, ensure that the surface of the steel pipe column is clean, so that the connection device can better fit the column, prevent dirt from affecting the connection strength, and a clean surface helps to improve the stability and durability of the connection;

[0037] S2: Install the first hoop structure, fix the first side plate and the middle plate together through the connecting piece, connect the second side plate and the middle plate, and ensure that the first side plate, the second side plate and the middle plate form a first hoop structure; form a basic fixing frame to provide a basis for subsequent installation. The first hoop structure is the core part of the entire connection device and provides preliminary fixation;

[0038] S3: Adjust the fit between the first hoop structure and the steel pipe column, put the first hoop structure on the steel pipe column, and make the first side plate and the second side plate fit on both sides of the steel pipe column respectively; ensure that the first hoop structure fits tightly on both sides of the steel pipe column, and the tight fit can ensure the stability of the connection and prevent slippage;

[0039] S4: Install the second hoop structure, fix the first curved panel 1 and the second curved panel 2 on the first side panel and the second side panel respectively, ensure that they are centrally symmetrically distributed, and connect the first curved panel 1 and the second curved panel 2 together through a connecting piece to form a second hoop structure; the second hoop structure increases the stability of the connection and provides adjustment capability. The second hoop structure provides additional fixing points and adjustment space, making the connection device more stable;

[0040] S5: Adjust the size of the second hoop structure. Use the adjusting bolt 4 to adjust the size of the second hoop structure so that it fits tightly with the steel pipe column. By adjusting the bolt 4, the second hoop structure can fit tightly with the steel pipe column to ensure the firmness of the connection. The adjustable structure enables the device to adapt to steel pipes of different diameters, thereby increasing the versatility of the connection device.

[0041] S6: Lock the connection device to ensure that the second clamp structure is tightened, and then use the adjusting bolt 4 to adjust the angle between the first clamp structure and the second clamp structure to make the entire connection device more stable. After the adjustment is in place, lock all the bolts to ensure that the connection device is firm and reliable. By locking the bolts, the stability and reliability of the connection device are ensured. The locked connection device can prevent the bolts from loosening due to vibration and other reasons, thereby maintaining the stability of the connection.

[0042] S7: Inspection and acceptance, check the stability of the connecting device, ensure that the connection between the steel pipe column and the connecting device is firm, and inspect the connecting device to ensure that it meets the design and use requirements.

[0043] When the size of the steel pipe column is large, the flange 3 is also large. However, since the larger flange 3 is not easy to align, in order to avoid misalignment and interference when installing the flange 3, in one embodiment, when installing the second clamp structure in S4, before operation, ensure that the positions of the first curved panel 1 and the second curved panel 2 are correct, and align the marks. When installing the flange 3, a step-by-step alignment method is adopted. First, roughly align, and then gradually adjust until it is fully aligned. Due to the large size of the large flange 3, once an alignment error occurs, the error accumulation will be very obvious. Through step-by-step alignment, the step-by-step alignment method can gradually reduce the installation error and avoid excessive errors caused by one-time alignment. In addition, the weight and volume of the large flange 3 make it very difficult to perform one-time precise alignment. By performing a rough alignment first, the flange 3 can be quickly installed to the approximate position, and then fine adjustments can be made, reducing the difficulty of installation.
