[0002] As the goal of the current era of architectural level, the engineering design of building curtain walls has emerged in various forms of architectural shapes. Among them, glass curtain walls, as a new form of building exterior decoration, have good permeability and light weight, and are widely used. In recent years, hyperbolic curtain walls have been used in more and more buildings due to their good permeability and beautiful appearance. With the vigorous development of my country's steel structure construction industry, single-layer grid shell structures are gradually being used to meet the needs of large spans, large spaces, and high lighting for a certain floor or a certain area. From the perspective of structural design, single-layer grid shell structures can meet the needs of high-end hotels and shopping centers for large spaces, large spans, and high lighting. The combination of the two is adopted by more architects.

[0003] At present, the vertical nodes of spherical gridshell glass skylights are mostly fixed on steel keels with aluminum alloy blocks and M6 stainless steel machine screws. This method is relatively complex and difficult to construct, and cannot meet the problems of on-site construction, such as the difficulty of fixing machine screws on steel keels, the overall rigidity and waterproofness of the nodes, and the inability to offset the offset when the gridshell is a curved surface. Utility Model Content

[0009] Preferably, a connecting frame is fixedly installed on one side of the metal hook edge close to the connecting folding groove, and the connecting frame is fixedly connected to the first transfer angle code.

[0010] Preferably, first through holes are correspondingly formed on the connection frame and the first adapter angle bracket, and first bolts for fixing the first adapter angle bracket to the connection frame are inserted into the first through holes.

[0013] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0014] 1) Factory processing can ensure the quality of glass panel units. The on-site construction process is simple, and only requires adjusting the hanging height and nailing, which saves construction time.

The construction node of the spherical lattice glass curtain wall comprises a plurality of glass plate units interconnected into a sphere, each glass plate unit comprises two glass plate bodies 1 interconnected, the two glass plate bodies 1 are fixedly mounted with metal hook edges 2 on the side end faces of the connection, and also comprises a connecting groove 3 for fixing on one side of the curtain wall keel 4 and a connecting assembly for connecting the metal hook edges 2 and the connecting groove 3, the connecting assembly comprises a first transfer angle code 5 fixedly connected to the glass plate body 1, and a second transfer angle code 6 fixedly connected to the connecting groove 3 and hingedly connected to the first transfer angle code 5. It should be noted that in this embodiment, the glass plate body 1 adopts ultra-white six-tempered triple-laminated double insulating glass, the connecting groove 3 is made of steel, and is fluorocarbon sprayed. By adjusting the vertical height of each glass plate unit, a straight surface fitting curved surface can be achieved, and the first transfer angle code 5 and the second transfer angle code 6 are hinged to release the stress of the hard contact between the glasses.

[0025] Furthermore, a connecting frame 10 is fixedly installed on the metal hook edge 2 on one side close to the connecting folded groove 3, and the connecting frame 10 is fixedly connected to the first adapter angle code 5. Preferably, a first through hole is correspondingly opened on the connecting frame 10 and the first adapter angle code 5, and a first bolt 7 for fixing the first adapter angle code 5 to the connecting frame 10 is inserted in the first through hole. A 4 mm thick toothed aluminum alloy gasket is provided between the first bolt 7 and the connecting frame 10.

[0027] 1) The wind pressure of the spherical skylight cannot be calculated according to the specification. According to the wind tunnel test, the value of each partition is different. Therefore, the force calculation is carried out through the Midas software. Under the most unfavorable load, the maximum deformation is 86mm. It is necessary to consider that under this forced displacement, the stress of the corner of the triangular plate is less than 58.8Mpa.

[0028] 2) Extract the coordinate value of the rod at the maximum deformation position and apply forced displacement, wind load and self-weight load.

[0029] 3) Through finite element analysis, the maximum stress of glass under forced displacement and maximum load is 15MPa<58.8MPa. The strength calculation is passed and the node is reliable.
