Description

Technical Field

[0001] The invention relates to the field of building glass curtain wall construction, and in particular to a double-twisted spiral glass curtain wall construction method based on BIM technology. Background Art

[0002] With the vigorous development of the construction industry, architectural concepts are constantly updated, and many new types of buildings have emerged, especially large-scale public buildings with special shapes, all of which adopt steel structures and curtain wall structures with multiple curved surfaces, large spans, and complex spaces. In a project undertaken by our company, it is a 21-story decorative building with the main structural types: steel structure and concrete mixed structure; the glass curtain wall building is 64.3 meters high, 13 meters wide on all four sides, and 3.1 meters high. Each floor is twisted 4.5 degrees counterclockwise, with a total of 20 floors twisted 90 degrees. The overall shape is a hyperbolic glass curtain wall. To achieve the hyperbolic effect of the glass curtain wall, we must first consider the hyperbolic shape of the internal keel and the grid effect of the glass surface material.

[0003] The section from 20m to 46m is divided into 16 equal parts, each with a width of 813mm, with 8 vertical partition seams located between the two turning lines, and the keel protruding outwards; Figure 1 As shown in the figure, if the glass curtain wall is constructed according to the original drawing, four grid columns JE, BD, FG, and JG and six glass panels need to be installed in the glass panel installation area of ​​each grid; because the main building body twists 4.5 degrees counterclockwise on each floor, the six glass panels also need to be bent to a certain extent to meet the fit installation of the six glass panels and the overall hyperbolic effect of the glass curtain wall; however, because the two quadrilateral glass panels JHDE and BFGH are non-coplanar quadrilaterals, there will be a 15mm warping problem at the H angle of the two quadrilateral glass panels JHDE and BFGH, making it impossible for the two quadrilateral glass panels JHDE and BFGH to be fit installed.

[0004] Therefore, how to optimize the construction process to ensure that the H angles of the two quadrilateral glass surface materials JHDE and BFGH will not curl up, ensure the hyperbolic effect of the overall glass surface material, quickly complete the installation and construction of the glass curtain wall, and greatly improve the construction speed, quality and safety are technical problems that need to be urgently solved by technical personnel in this field. Summary of the invention

[0005] The present invention aims to solve the above problems, and thus provides a double-twisted spiral glass curtain wall construction method based on BIM technology. By utilizing the advantages of BIM technology and adjusting the construction sequence of columns, beams and glass surface materials without changing the appearance of the glass curtain wall, the problem that during the construction of the double-twisted spiral glass curtain wall, the vertical partition seam position of the local glass surface material is between two turning lines, the keel protrudes outward, and the glass surface material will warp when installed at this position is solved.
