单层厂房网架结构体系,系指厂房的屋盖承重结构采用平板网架结构,与其相应的基础、柱子、墙体、屋面和通风采光以及车间内部运输等形成一套作法。由于屋盖以下部分和一般平面结构体系相似,因而本文只略谈厂房屋盖网架结构体系的设计。网架结构体系空间刚度大;抗震性能好;悬挂吊车或其他传送设备非常灵活;而且有利于标准化工厂化生产;其用钢量比较省,如果使用恰当、设计又合理,可以做到用钢量接近于同条件的钢筋混凝土平面结构 The single-story factory grid structure system means that the roof structure of the factory building adopts a flat-screen grid structure and forms a set of practices with its corresponding foundations, pillars, walls, roofs, ventilation and lighting, and internal transportation of the workshop. Since the lower part of the roof is similar to the general plane structure system, this article only briefly discusses the design of the roof grid structure system of the factory. The space frame structure system has large space rigidity, good anti-seismic performance, very flexible suspension cranes or other transmission equipment, and is conducive to standardizing industrialized production; the amount of steel used is relatively low, and if used properly and the design is reasonable, steel consumption can be achieved. Close to the same conditions of reinforced concrete plane structure
