[0024] A construction method for a decorative petal column variable-section ring tube comprises the following steps: S1. establishing a BIM model of a decorative metal petal column ring tube, and measuring and releasing the specific installation positions of the decorative petal column variable-section ring tube and a support 4 of each layer; S2. welding and installing the support 4 and a mounting member 8 on the corresponding position of a main steel column 1; S3. sequentially installing a second sub-arc tube 32, a fifth sub-arc tube 35, a connecting core 5, a first sub-arc tube 31, a third sub-arc tube 33, and a fourth sub-arc tube 34; S4. fixing the first sub-arc tube 31, the second sub-arc tube 32, the third sub-arc tube 33, the fourth sub-arc tube 34, and the fifth sub-arc tube 35 using a second rivet 7.

[0025] Step S1 specifically includes: S11. Establishing the BIM model of the entire decorative metal petal column and the variable-section ring tube of the decorative petal column, and using parameterization to extract the processing dimensions of the decorative metal petal column ring tube material; S12. Using an electronic theodolite in conjunction with a steel tape measure to measure and lay out the specific installation positions of each layer of the decorative petal column variable-section ring tube and the support 4, and mark them.

[0026] The specific steps in step S2 are as follows: according to the position determined by measuring and laying out, the anti-rust coating on the steel structure is removed in advance, and then the support 4 is welded to the corresponding steel column position by welding; according to the position determined by measuring and laying out, the anti-rust coating on the main steel column 1 is removed in advance, and then the end of the mounting part 8 intersecting with the main steel column 1 is welded to the corresponding main steel column 1 by welding.

[0027] Step S3 specifically includes: S31. preliminarily fixing the second sub-arc tube 32 and the fifth sub-arc tube 35 on the support 4; S32. inserting the connecting core 5 into one end where the first sub-arc tube 31, the third sub-arc tube 33 and the fourth sub-arc tube 34 are to be installed; S33. sequentially connecting the first sub-arc tube 31 and the second sub-arc tube 32, the second sub-arc tube 32 and the third sub-arc tube 33, the fourth sub-arc tube 34 and the fifth sub-arc tube 35 through the connecting core 5 and fixing them through the first rivet 6.

Set the decorative color of the decorative metal petal column, and carry out anti-corrosion and uniform color treatment on the entire decorative metal petal column according to the set decorative color, and archive it. Use unified paint for anti-corrosion treatment and color treatment. In order to improve the service life of the entire decorative metal petal column and ensure the uniformity of the decorative effect of the entire decorative metal petal column, after the entire construction is completed, it is necessary to use the designed paint to carry out anti-corrosion and uniform color treatment on the entire decorative metal petal column. Unified paint can be used for anti-corrosion and color matching. After completing the construction of the entire decorative metal petal column and the decorative metal petal column ring tube, complete the cleaning and color, and archive the relevant information.

[0029] Embodiment: A decorative metal petal column variable-section ring tube and construction method are mainly realized through the following structures: a first sub-arc tube 31, a second sub-arc tube 32, a third sub-arc tube 33, a fourth sub-arc tube 34, a fifth sub-arc tube 35, a support 4, a mounting part 8, a connecting core 5, a first rivet 6, a second rivet 7, a main steel column 1, and a spiral steel column 2.

[0030] The first sub-arc tube 31 is located outside the main steel column 1 and connected to the second sub-arc tube 32 through a connecting core. The first sub-arc tube 31 and the second sub-arc tube 32 are fixed by a second rivet 7 to solve the decoration problem on the right side of the variable cross-section ring tube.

[0031] The second sub-arc tube 32 is located between the first sub-arc tube 31 and the third sub-arc tube 33, and is connected to the first sub-arc tube 31 and the second sub-arc tube 32 through the connecting core. The first sub-arc tube 31 and the third sub-arc tube 33 are fixed through the second rivet 7, so as to solve the decoration problem of the external display surface of the variable cross-section ring tube.

[0032] The third sub-arc tube 33 is located between the second sub-arc tube 32 and the fourth sub-arc tube 34. One end of the third sub-arc tube 33 is fixed to the main steel column 1 through a mounting piece. The third sub-arc tube 33 and the second sub-arc tube 32 are connected through a connecting insert. The second sub-arc tube 32 and the third sub-arc tube 33 are fixed respectively through a second rivet 7. The third sub-arc tube 33 mainly solves the problem that the annular arc tube is forced to be interrupted due to the change in position of the main steel column 1 and the spiral steel column 2 and the inability to install.

[0033] The fourth sub-arc tube 34 is located between the third sub-arc tube 33 and the fifth sub-arc tube 35. One end of the fourth sub-arc tube 34 is fixed to the main steel column 1 through a mounting piece. The fourth sub-arc tube 34 and the fifth sub-arc tube 35 are connected through a connecting insert. The fourth sub-arc tube 34 and the fifth sub-arc tube 35 are fixed respectively through a second rivet 7. The short-section design of the fourth sub-arc tube 34 solves the problem of arc tube discontinuity caused by position change of the main steel column 1 and the spiral steel column 2.

[0034] The fifth sub-arc tube 35 is located between the first sub-arc tube 31 and the fourth sub-arc tube 34 and is fixed to the support by the first rivet 6 to achieve fixation of both ends thereof, thereby solving the problem of decoration of the inner side of the petal shape.

[0035] Support 4: Located between the main steel columns 1, the specific structure is detailed in patent manuscript 42, which provides a fixed installation foundation for the annular arc tube, and at the same time realizes the adjustment of the arc tube installation position and the measurement error of the welding machine.

[0036] Mounting parts 8: There are two of them located between the main steel column 1 and the third sub-arc tube 33 and the fourth sub-arc tube 34. The spacing between the mounting parts can solve the problem that the arc tube cannot be installed due to the narrow space and the problem of arc tube bending. The other one is between the main steel column 1 and the first sub-arc tube 31, which solves the problem of installation and fixing support of the first sub-arc tube 31 and ensures the installation stability of the first sub-arc tube 31.

[0037] The connecting core 5 is located between the first sub-arc tube 31 and the second sub-arc tube 32, the second sub-arc tube 32 and the third sub-arc tube 33, and the fourth sub-arc tube 34 and the fifth sub-arc tube 35. The material of the connecting core is consistent with the material of the ring tube. Through this connecting core, the need for welding or bolt fixing during connection in a conventional construction method is avoided, which is convenient for on-site construction and avoids the problem of inconvenient installation due to the use of a whole circular arc tube. Rapid installation is achieved, and the installation efficiency of a single circular arc tube is improved.

[0038] The first rivet 6 is a finished accessory, used to fix the connector on the support to the arc tube, to ensure the installation stability and reliability of the arc tube and the support. In order to ensure aesthetics, it is fixed in a hidden position that is not easily visible from the viewing angle.

[0039] The second rivet 7 is a finished product accessory, used to fix the corresponding connecting core to the arc tube. In order to ensure aesthetics, it is fixed in a hidden position that is not easily visible from the viewing angle. The second rivet 7 ensures the stability and reliability of the installation of the arc tube, avoiding dislocation and deformation that affect the construction quality.

[0040] Main steel column 1: This is an important part of the main body of the decorative metal petal column, which cooperates with the spiral steel column 2 to form the petal-shaped main part. Made of steel structure, it is located in the middle part of the variable-section decorative ring tube, providing an installation foundation for the support plates and mounting parts outside the petal column, so as to transmit the force of the roof steel structure to the foundation raft.

[0041] Spiral steel column 2: This is an important part of the main body of the decorative metal petal column, which cooperates with the main steel column 1 to form the petal-shaped main part. Made of steel structure, it is located in the middle part of the variable-section decorative ring tube, providing an installation foundation for the support plate and mounting parts outside the petal column, so as to transmit the force of the roof steel structure to the foundation raft.

[0042] The above-mentioned decorative metal petal column variable cross-section ring tube involves two situations. The above only exemplifies the components and functions of the ring tube when the spiral steel column rises, which causes the ring tube to be interrupted. When the spiral column rises with a certain space and does not need to be interrupted, the components and functions of the components are the same as when it is interrupted.

[0043] The construction method for the variable-section ring tube of the petal column that does not require interruption includes the following steps: A1.

Insert the connecting core 5 into the end where the first sub-arc tube 31, the third sub-arc tube 33 and the fourth sub-arc tube 34 are to be installed; A33. Sequentially connect the first sub-arc tube 31 and the second sub-arc tube 32, the second sub-arc tube 32 and the third sub-arc tube 33, the fourth sub-arc tube 34 and the fifth sub-arc tube 35 through the connecting core 5 and fix them through the first rivet 6; A34. Connect the ends of the third sub-arc tube 33 and the fourth sub-arc tube 34, the first sub-arc tube 31 and the fifth sub-arc tube 35 that are not fixed by the first rivet 6 to each other.

[0047] It also includes the steps of anti-corrosion treatment and acceptance: A6.
