Description

Technical Field

[0001] This invention relates to the field of curtain wall technology, and in particular to a large-span beamless curtain wall. Background Technology

[0002] With the development of the building curtain wall industry, some large public buildings are beginning to pursue large spans, large spaces, and high transparency. The supporting structure of large-span curtain walls usually adopts steel structure keel. Conventional large-span steel structure systems have a large visible cross section inside the steel structure. If the steel columns adopt conventional steel plate welding process, the weld seams will be visible inside, affecting the interior effect. When using conventional steel, the pressure plates are connected with screws, which requires pre-drilling threaded holes and on-site hole alignment, which brings inconvenience to processing and installation. Conventional steel structure systems need to set up steel beams to support the self-weight of the glass panels, which not only affects the transparency of the facade effect, but also increases costs.

[0003] A "Large-Span Curtain Wall Structure" disclosed in Chinese patent literature, publication number CN208701974U, describes a large-span curtain wall structure with front and rear columns. Adjacent front columns are connected by horizontal beams, and glass panels are mounted on bases on the front columns and horizontal beams. The front and rear columns are connected by connecting plates. This utility model can be installed between higher floors of a building, with the rear and front columns connected together by bolts. However, the structure of Chinese patent CN208701974U is simple and does not solve the aforementioned problems. Summary of the Invention

[0004] This invention solves the problems of exposed welds, inconvenient installation, and poor transparency of the facade in traditional large-span curtain walls. It proposes a large-span beam-free curtain wall, which ensures structural strength by setting main columns and embedded columns, combined with cross-shaped bases, so that there are no exposed welds inside and outside, improving installation efficiency and making the facade more transparent.
