Description

A super-large hyperbolic unitized glass curtain wall based on BIM technology Technical Field

[0001] This invention relates to the field of glass curtain walls, and in particular to an ultra-large hyperbolic unitized glass curtain wall based on BIM technology. Background Technology

[0002] As urban architectural designs evolve towards complex curved surfaces and ultra-large scales, hyperboloid and free-form glass curtain walls are increasingly being used in commercial complexes, transportation hubs, and public cultural buildings. These curtain walls typically employ large-size glass units combined with spatial steel keels, placing higher demands on component processing precision, node connection strength, and overall stress coordination. Especially under ultra-large hyperboloid structures, the glass segmentation is diverse, the keel spatial positioning is complex, and the connection structure has multiple layers, making construction and installation significantly more difficult than conventional curtain wall systems.

[0003] In existing technologies, some curtain wall structures still rely on single or simplified support and connection methods, resulting in an unreasonable stress path and a tendency for stress concentration at local nodes, affecting glass safety and structural durability. Meanwhile, traditional construction methods relying on two-dimensional drawings and on-site layout cannot accurately reflect the true spatial form of hyperbolic surfaces. Assembly errors and node conflicts easily occur between components, leading to repeated on-site adjustments. This not only increases construction time and costs but also raises the risk of inconsistent waterproofing node treatment and subsequent leakage. Although some projects have begun to introduce BIM technology for design assistance, it is mostly limited to visualization or simple layout guidance and has not yet been deeply integrated with the curtain wall structure node design and unit assembly system, making it difficult to fully leverage its technical advantages in the refined design and construction coordination of complex curved curtain walls.

At the same time, a connecting element is installed from top to bottom inside the outer steel keel 4. The connecting structure 7 includes an aluminum alloy column 71, a steel keel core 72, a second aluminum alloy sub-frame 73, an aluminum alloy pressure plate 74, and an aluminum alloy pressure plate assembly 75, forming a vertical connection system with the outer steel keel 4 capable of supporting glass.

The support mechanism 11, after cooperating with the first aluminum alloy hanging bracket 51, the base plate 52, and the card seat 53, is fixed to the front end of the inner steel keel 8 through the bracket 13. At the same time, a stabilizing mechanism 14 is installed at the lower end of the outer steel keel 4 through the bracket 16, and a bottom connecting mechanism 17 and a base frame 18 are set at the lower end of the outer steel keel 4 to provide multiple points of support at the top, bottom, and middle for subsequent glass installation.

[0036] After completing the keel and all supporting and connecting components, the top of the first outer glass 1 is first attached to the first aluminum alloy sub-frame 55, and the first outer glass 1 is fixed to the frame formed by the aluminum alloy column 71 and the steel keel core 72 through the aluminum alloy pressure plate 74 and aluminum alloy pressure plate assembly 75 of the two sets of connecting structures 7 at the upper end. At the same time, the third aluminum alloy sub-frame 104 in the fixing structure 10 is used to horizontally connect the junction of the first outer glass 1 and the second outer glass 2. Then, the second outer glass 2 is lifted and locked by the corresponding connecting structure 7 at the lower end and the second aluminum alloy hanging bracket 141, aluminum alloy bracket 142 and lifting component 143 in the stabilizing mechanism 14, so that it forms a stable connection with the outer steel keel 4 and the inner steel keel 8.

[0037] BIM technology was introduced into the design and construction of this super-large hyperbolic unitized glass curtain wall. Three-dimensional parametric modeling was performed on all components, including the first outer glass layer 1, the second outer glass layer 2, the third outer glass layer 3, the outer steel keel 4, the inner steel keel 8, the upper support structure 5, the lower support structure 6, the connecting structure 7, the fixing structure 10, the stabilizing mechanism 14, and the bottom connecting mechanism 17. A precise spatial curvature model was established to collaboratively verify the dimensions of the hyperbolic glass segments, the installation angle of the aluminum alloy sub-frame, and the position of the steel keel nodes, enabling pre-assembly and assembly sequence simulation. Simultaneously, BIM was used for collision detection and stress path analysis to identify spatial conflicts and installation interference between the outer steel keel 4 and the inner steel keel 8, brackets 16, supports 13, and various hanging brackets, water channel brackets, waterproof membranes, and galvanized angle steel. The optimized node construction methods were then used to guide factory prefabrication and on-site assembly, ensuring high-precision alignment and installation of the glass units, keel system, and waterproof structure, thereby improving overall construction efficiency, structural safety, and the curtain wall's airtightness, watertightness, and wind resistance.
