国外单层厂房广泛采用装配式钢筋混凝土、预应力混凝土结构和轻型围护材料的结构,且跨度不断增大,是一种普遍趋势。联邦德国厂房结构体系有薄腹梁屋盖体系、锯齿形屋盖体系、板架合一(或板梁合一)屋盖体系等。英国的单层厂房平面布置一般较紧凑,大都为联跨。波兰轻钢结构体系只在屋面和墙面围护结构采用了轻型板材结构,这些围护结构是压成各种波形的镀锌薄钢板,中间夹轻型保温层;承重结构仍采用传统的梁柱或屋架柱 The structure of prefabricated reinforced concrete, prestressed concrete structures, and lightweight enclosure materials is widely used in single-floor foreign plants, and the span is continuously increasing. This is a common trend. The structural system of the Federal Republic of Germany is a thin-belly beam roof system, a zig-zag roof system, and a plate-in-one (or plate-beam-in-one) roof system. The layout of the UK’s single-storey factory buildings is generally more compact, most of which are joint spans. Lightweight steel structure systems in Poland only use lightweight sheet structures for roofing and wall cladding structures. These envelope structures are galvanized sheet steel pressed into various waveforms with a light insulation layer in between; the load-bearing structure still uses traditional beams and columns.
