Technical Field

Background

With the development of society and the rapid progress of construction technology, the requirements of people on construction are not only meeting the basic demands of survival and production, but also having higher-level requirements on construction, such as requirements on modeling, space and effect. Building facades are often the first part of visitors to see, are the most intuitive parts to feel, and are the flash points which are easiest for people to remember the building, so the advantages and disadvantages of one building depend on the facade effect to a great extent. In recent years, the vertical-face curtain wall has relatively rapid development, in particular to a single-layer cable net curtain wall, which is favored by architects because of strong permeability and good building effect.

Meanwhile, the single-layer cable network curtain wall has higher requirement on peripheral anchoring structures due to the characteristic of large stress of the inhaul cable, and a concrete structure with higher rigidity is generally adopted, but a steel structure is rarely adopted; meanwhile, the traditional cable curtain wall is in accordance with the design principle that vertical cables bear glass gravity and horizontal cables bear wind load, so that most of the cable curtain wall can only adapt to vertical forms, and development and popularization of single-layer cable curtain walls are limited to a great extent.
