DETAILED DESCRIPTION

[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0018] The following is a detailed description of the implementation method of the present invention in conjunction with the accompanying drawings. Only some embodiments are described, not all embodiments. For the purpose of clarity, representations and descriptions that are not related to the present invention are omitted in the drawings and descriptions.

[0019] In order to have a clearer understanding of the technical features, purposes and beneficial effects of the present invention, the technical solution of the present invention is now described in detail below. Obviously, the implementation cases described are part of the embodiments of the present invention, not all of the embodiments, and cannot be understood as limiting the scope of the implementation of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0020] like Figure 1 , Figure 3 As shown, the present invention provides a decorative metal petal column, including: a bottom support, a horizontal steel beam, and also including: a steel column, a roof steel structure, an ordinary ring tube, and a decorative ring tube; the steel column includes a main steel column and a spiral steel column; the bottom support is arranged at the bottom of the decorative metal petal column, and the upper end of the bottom support is welded to the steel column; the lower end of the steel column is welded to the bottom support, and the top of the steel column is welded to the roof steel structure; the horizontal steel beam is fixed between the main steel column and the spiral steel column by welding; there are a plurality of ordinary ring tubes arranged on the main steel column from bottom to top; there are a plurality of decorative ring tubes, each of which is respectively arranged at the intersection of the main steel column and the spiral steel column.

[0021] The bottom support is located at the lowest part of the decorative metal petal column, providing a rooting foundation for the entire petal column and transferring the overall force of the petal shape to the raft foundation of the main structure of the building.

[0022] Steel column as a whole, such as Figure 2 As shown, the spiral petal shape is: petal shape with large top and small bottom. It consists of two parts, namely the main steel column located in the center of the ring tube and the spiral steel column located outside the ring tube, which are welded to the steel structure with reserved supports at the bottom, and the top is connected to the roof steel structure by welding. The steel column presents a spiral petal shape from the foundation to the roof, which is large at the top and small at the bottom, and unfolds like a petal, echoing the roof steel structure, forming the main part of the entire petal column, providing for the ordinary ring tube and variable-section ring tube outside the main body.

[0023] Horizontal steel beam: located between the main steel column and the spiral steel column, the main steel column and the spiral steel column are connected by welding to enhance the firmness of the main steel column and the spiral steel column, and prevent the petal column from tilting or deforming outward under the action of overall gravity due to the change from small to large from the bottom to the top of the petal column.

[0024] The roof steel structure is an annular mesh structure, which is used to weld and connect the top of the steel column. As an important part of the main steel structure of the building, the roof steel structure is not only the roof of the building, but also an important part of the top of the petal column. The shape of the entire petal column is realized by unfolding the petal shape.

[0025] Ordinary ring tube: Made of lightweight high-definition aluminum alloy, fixed on the ring tube support by rivets. Located outside the main steel column, it gradually rises from the bottom to the top according to a certain arrangement pattern according to the shape of the main steel column, and is woven into a single columnar tree support pile. There are multiple groups of single tree branches installed in a certain pattern to form a whole tree shape.

[0026] Decorative ring pipe: located between the main steel column and the spiral steel column, it mainly solves the installation problem of the ring pipe at the intersection of the main steel column and the spiral steel column. Made of lightweight and high-definition aluminum alloy, it is fixed to the ring pipe support and mounting parts by rivets.

[0027] A construction method for a decorative metal petal column comprises the following steps: S1. Determine the construction plan of the decorative metal petal column and establish the BIM model of the decorative metal petal column. Before the formal construction, organize relevant personnel to prepare the construction plan of the decorative metal petal column, prepare, review and verify the construction plan (if necessary), and complete the plan disclosure to ensure the legality and compliance of the construction, and make relevant preparations for personnel, materials, machinery and equipment to prepare for the formal construction in advance.

[0028] To complete the construction plan of this decorative petal column, it is necessary to determine the final plan, use BIM technology to build a model of this petal column, realize visualization, parameterization, and annotation, and use BIM dynamic simulation construction to complete the technical briefing work for project management personnel and project operation personnel, and clarify the requirements such as attention, key points and difficulties, and quality standards in the construction process of decorative petal columns.

[0029] Based on the processing parameters extracted in advance using the BIM model, a professional factory was commissioned to process key components such as the bottom support of the decorative petal column, retractable and adjustable connectors, ring pipe supports, variable-section ring pipes and ordinary ring pipes.

[0030] During processing, in order to facilitate on-site installation, it is necessary to number the corresponding installation locations, ensure the processing accuracy of the materials, protect the finished products, and prepare for on-site construction.

[0031] S2. Measure and lay out the construction site. According to the measurement control lines reserved in advance on site, use total stations, levels, steel tape measures and other measurement and layout tools to complete the measurement and layout of the decorative petal-shaped embedded bottom supports and the decorative petal column positions, and do a good job of review to ensure the precision and accuracy of the measurement and layout.

[0032] S3. Install the bottom support according to the control line of the measurement and positioning. According to the previous measurement and positioning control line, the bottom support is pre-buried and the position control is done in advance, the raft concrete is poured and maintained, and the concrete pouring of the hollow part of the bottom support center is completed, in preparation for the next step of steel column installation.

[0033] S4. Install steel columns from the bottom up layer by layer, and install the roof steel structure after the main steel columns are installed.

[0034] In the step S4, the steel columns are installed upward layer by layer, such as Figure 4 As shown, it specifically includes the following sub-steps: the steel column is divided into five layers for installation, and each layer of steel columns is a main steel column and a spiral steel column cross-connected spirally. When installing the fourth layer of steel columns, a ribbon structure is set to build a petal frame; a tree-like column roof is set on the top of the fifth layer of steel columns to fix the main structure of the decorative metal petal column; the steel column is divided into five layers for installation, and a horizontal steel beam is set at the connection of each layer of steel column structure for connection and fixation.

[0035] After completing the bottom support in advance, remove the anti-rust paint on the concrete and steel columns, and then use professional lifting tools and operating frames to lift the main steel columns and spiral steel columns from the bottom, layer by layer (involving multiple layers) upwards. Use full welding to complete the welding construction, and carry out inspection and control of the construction quality during the process to ensure its construction quality.

[0036] During the installation of steel columns, the installation of horizontal rigid beams needs to be completed simultaneously. The horizontal rigid beams can be used to install and fix the main steel columns and spiral steel columns, thereby enhancing the stability and firmness of the steel column installation.

[0037] Since the steel columns are larger at the top and smaller at the bottom, and since the main structure and roof form an integral whole, and considering that there may be a time interval between the roof and steel column construction, it is necessary to adopt temporary support and fixing measures for the constructed steel columns to ensure that the steel columns will not be deformed or damaged due to gravity and material stress.

[0038] After completing the construction of the main steel columns, the construction of the roof steel structure is carried out. Because the roof steel structure is related to the steel structure construction of the entire building, it must be basically consistent with the steel structure construction of the entire building to ensure the integrity and safety of the construction.

[0039] S5. Extract coordinate points based on the BIM model to determine the installation position of the ring pipe, and conduct secondary measurement and layout. After completing the steel column construction, it is necessary to use total stations, levels, steel tape measures and other measurement and layout tools to determine the installation position of the ring pipe based on the coordinate points extracted from the BIM model, and conduct secondary measurement and layout to measure and lay out the installation spacing and installation position of the ring pipe in preparation for the next step of ring pipe installation.

[0040] S6. Install the common ring tubes and decorative ring tubes one by one from bottom to top. On the basis of measurement and layout, install the decorative petal-shaped ring tube supports in advance, and then install the decorative ring tubes from the bottom to the top by installing them one by one from bottom to top according to the design drawings and BIM.

[0041] During the installation of the ring pipe, attention should be paid to the butt joints of the ring pipe to avoid gaps that are too large. At the same time, the support should be adjusted to solve the stress error and measurement error caused by the stress of the steel structure to ensure the installation level of the ring pipe.

[0042] When constructing variable-section annular pipes, it is necessary to pay attention to smooth installation and ensure installation quality to avoid problems such as inability to install the annular pipe due to variable cross-section and poor installation molding quality.

[0043] The rivets that fix the ring tube should be fixed and installed in an area that does not affect the overall visual effect to ensure a decorative petal-shaped molding effect.

[0044] It also includes rust removal, painting, acceptance and filing steps: after the construction is completed, use anti-rust paint for anti-rust treatment, and use decorative topcoat to decorate the surface of the decorative metal petal column in combination with the decoration style, and then accept and file it. Before using anti-rust paint for anti-rust treatment, grind and polish the welding joints. In order to increase 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 anti-rust paint for anti-rust treatment, and use decorative topcoat in combination with the designed decoration style to ensure the uniformity of the entire style. Anti-corrosion and spraying can use a unified blending paint.

[0045] Before formal painting, the designed welding position needs to be smoothed and polished using professional grinding machinery to ensure the uniformity of the final paint. Painting requires multiple spraying processes and it is strictly forbidden to spray in one go.

[0046] After the construction of the entire decorative metal petal column and the decorative metal petal column ring tube is completed, the cleaning and coloring are completed, and the relevant information is archived. After the cleaning and acceptance are completed, the finished product of the decorative petal column is well protected to avoid damage to the finished decorative petal shape when other areas are constructed. To ensure the subsequent construction of other parts of the decoration until the entire project is completed.

[0047] The present invention solves the rooting problem of the decorative petal column by pre-embedded bottom support, and solves the problem of the trunk body of the bionic tree by using the main steel column and the spiral steel column to spirally expand from bottom to large. The petal weaving problem is solved by using a combination of lightweight and high-strength ordinary ring tubes and variable-section ring tubes. The steel column has good bearing capacity and stability to realize the decorative petal-shaped main body, and the decorative aluminum alloy is lightweight and high-strength to support the decorative ring tube. It effectively avoids quality accidents and safety accidents such as stress and gravity deformation, collapse, etc. caused by the special modeling structure under the action of gravity. It ensures the structural safety and the final decorative effect, and has good application and promotion value.

[0048] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
