[0055] The following is for reference. Figures 1 to 10 This invention describes a method for detailed design of a hyperbolic helical steel structure staircase according to an embodiment of the present invention.

[0056] The method for detailed design of a hyperbolic spiral steel structure staircase according to an embodiment of the present invention includes the following steps: S100. Using CAD software to lay out the three-dimensional stair beams on both sides of the staircase; S200. Importing the three-dimensional CAD line model into TEKLA software, and using TEKLA software to establish a three-dimensional solid model of the staircase; S300. Using RHINO software to complete the BIM verification of the three-dimensional solid model of the staircase.

[0057] The hyperbolic spiral steel structure staircase detailed design method of this invention first uses CAD software to establish a 3D CAD line model of the stair beam's 3D bending and twisting structure. Then, using TEKLA software, a 3D solid model of the entire staircase is established based on the 3D CAD line model of the stair beam. Combining the advantages of the two software programs, the design is ingenious and the establishment process is fast and efficient. Finally, RHINO software is used to complete the BIM verification of the staircase's 3D solid model, making the establishment of the staircase's 3D solid model more accurate. In addition, using TEKLA software, component processing drawings and part unfolding drawings of the staircase can also be generated based on the 3D solid model, which facilitates subsequent construction and solves the problem of difficult detailed design of hyperbolic spiral steel structure staircases.

[0058] The steps S100 to S300 of the hyperbolic spiral steel structure staircase detailed design method according to an embodiment of the present invention will be described in more detail below.

[0059] In some embodiments of the present invention, such as Figures 1 to 5 As shown, step S100 specifically includes the following processes: S110. Using CAD software, the spiral center spline curve of the ladder beam is laid out, and the ladder beam is divided into multiple ladder beam segments along the spiral center spline curve; S120. Using CAD software, with the points on the spiral center spline curve as control points, multiple ladder beam cross sections in the length direction of one of the ladder beam segments are laid out; S130. Using CAD software, with the points on the spiral center spline curve as control points, the end faces at both ends of the ladder beam segment are laid out, and the end faces are defined as ladder beam segment surfaces; S140. Repeating steps S120 and S130, the three-dimensional CAD line model of the ladder beam is laid out.

[0060] In this embodiment, based on the on-site hoisting plan, taking into account the hoisting weight, the structure of the ladder beam components and parts, the ladder beam can be divided into multiple ladder beam segments. Then, using the points on the spiral center spline curve of the ladder beam as control points, the cross-sections and segment surfaces of all ladder beam segments are laid out sequentially, thus forming a three-dimensional CAD line model of the ladder beam. This makes modeling faster, more efficient, and more accurate.

[0061] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, step S100 further includes: S150. The staircase includes an inner spiral section and an outer spiral section. A plumb bob projection surface is generated for the cross-section of the stair beams in the inner spiral section. Specifically, a plumb bob projection surface is generated for the cross-section of the stair beams in the inner spiral section at locations with greater curvature. This setup makes the 3D CAD line model of the stair beams more accurate, facilitating subsequent 3D solid modeling.

[0062] In some embodiments of the present invention, step S110 specifically includes the following processes: S111. Import the control point coordinates of the center line of the ladder beam in the CAD design drawing into an EXCEL table, and sort the control point coordinates sequentially along the length direction of the center line of the ladder beam; S112. Perform data formatting processing on the control point coordinates in the EXCEL table; S113. Import the processed data in the EXCEL table into CAD software to obtain a spiral center spline curve, and divide the ladder beam into multiple ladder beam segments along the spiral center spline curve.

[0063] In this embodiment, the control point coordinates are first sorted using an EXCEL spreadsheet, and then imported into CAD software to accurately obtain the spiral center spline curve.

[0064] In some embodiments of the present invention, such as Figure 2 As shown, step S120 specifically includes the following processes: S121. Draw multiple cross-sections of the ladder beam segments in CAD software and save the multiple cross-sections as block attributes; S122. Establish a local coordinate system with the control point as the origin, the normal plane of the spiral center spline curve as the XY plane, and the tangential direction of the control point as the Z-axis direction; S123. Insert the cross-sections into the XY plane of the local coordinate system to obtain the ladder beam cross-section. By drawing the cross-sections of the ladder beam segments in CAD software and then inserting the cross-sections into the normal plane of the spiral center spline curve, the ladder beam cross-section can be obtained. The establishment process is quick and convenient.

[0065] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, step S200 specifically includes the following processes: S210. Import the 3D CAD line model into TEKLA software, and use the triangle simulator function of TEKLA software to lay out the 3D solid model of the stair beam; S220. Use TEKLA software to lay out the 3D solid models of the stair platform beam and treads to obtain the 3D solid model of the stair. Since TEKLA software is not convenient to directly complete the creation of the 3D solid model of the stair beam, in this embodiment, the 3D CAD line model of the stair beam is first imported into TEKLA software, and the 3D solid model of the stair beam can be laid out using TEKLA software. Then, the 3D solid models of other stair components, such as the 3D solid models of the stair platform beam and treads, are laid out to obtain the 3D solid model of the stair. The creation process is simple and convenient.

[0066] In some embodiments of the present invention, such as Figure 8As shown, step S300 specifically includes the following processes: S310. Import the 3D solid model of the staircase into the CAD software to obtain a 3D CAD solid model; S320. Divide the 3D CAD solid model into different layers according to the different component types of the staircase; S330. Import the 3D CAD solid model into RHINO software and perform BIM clash check between the 3D CAD solid model and the architectural design model and the curtain wall cladding model; S340. Based on the BIM clash check results, modify the model lofting and repeat steps S310 to S330 until the BIM clash check results meet the requirements, finally obtaining the 3D fabrication model of the staircase.

[0067] In this embodiment, by performing BIM collision verification between the 3D CAD solid model and the architectural design model and the curtain wall cladding model, the accuracy of the 3D model of the staircase can be determined based on the BIM collision verification results. If the 3D model of the staircase is inaccurate, it can be adjusted until the BIM collision verification results meet the requirements, and finally an accurate 3D processing model of the staircase is obtained to facilitate subsequent processing of the staircase.

[0068] In some embodiments of the present invention, the detailed design method for a hyperbolic spiral steel structure staircase further includes the step: S400. Using TEKLA software, generate component fabrication drawings for the staircase. Specifically, as... Figure 9 As shown, the process includes the following steps: S401. In the TEKLA model, assign unique numbers to the stair components and parts; S402. Select machining dimension control points in the 3D solid model to add auxiliary coordinate points, mainly component end contour points, partition control points, etc.; S403. Set up a factory machining local coordinate system for the stair beam components; S404. Generate detailed machining drawings of the stair beam components; S405. Generate detailed machining drawings of the platform beams and treads. In this embodiment, generating machining drawings of the stair components facilitates subsequent machining of the stair components.

[0069] In some embodiments of the present invention, the method for detailed design of hyperbolic spiral steel structure staircases further includes the step: S500. Using the triangle unfolder function of TEKLA software, generate unfolded drawings of staircase parts.

[0070] Specifically, such as Figure 10 As shown, the triangle unfolder function of TEKLA software is used to unfold the flanges and webs of the staircase, generating a part unfolding drawing of the staircase to facilitate subsequent processing of the staircase parts.

[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
