近年来在医药工业厂房设计中，大量采用轻钢结构，其中以门式钢架为主，有单跨和多跨。 门式轻型钢架结构与钢筋混凝土结构相比，有其独特的优点：
In recent years, in the design of pharmaceutical industry factories, a large number of light steel structures have been used, with portal steel frames being the main type, with single and multiple spans. Compared with reinforced concrete structures, portal light steel frame structures have unique advantages:
1．柱网布置灵活，跨度可达36m州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定空压机 高碑店养老院，纵向温度区段长度允许300m，横向温度区段长度允许150m，这种结构用于医药工业厂房，符合洁净厂房不设变形缝的要求。
1. The column grid layout is flexible, with a maximum span of 36m. The length of the longitudinal temperature section is allowed to be 300m, and the length of the transverse temperature section is allowed to be 150m. This structure is used in pharmaceutical industry factories and meets the requirement of clean factories without deformation joints.
2．门式结构坡屋面空间较大，作为技术夹层节约投资。
2. The door structure sloping roof has a large space, which can save investment as a technical interlayer.
3．抗震性能好，钢结构本身具有较好的延性，能够充分耗散地震能。另外，由于重量轻，地震力很小。 设计经验表明：当抗震设防烈度为7度时，一般不需做抗震验算；当为8度及以上时，横向刚架和纵向刚架均需做抗震验算。
3. The seismic performance is good, and the steel structure itself has good ductility, which can fully dissipate seismic energy. In addition, due to its light weight, the seismic force is very small. Design experience shows that when the seismic fortification intensity is 7 degrees, seismic verification is generally not required; When it is 8 degrees or above, both the transverse and longitudinal rigid frames need to undergo seismic verification calculations.
4．轻钢结构重量轻，节省了基础投资。
4. The lightweight steel structure is lightweight and saves basic investment.
5．外墙采用轻型复合钢板，可以满足厂房泄爆要求。
5. The exterior wall is made of lightweight composite steel plates, which can meet the requirements for explosion venting in the factory building.
6．现场组装、机械化施工、确保质量和进度，投产早、见效快。 医药工业应用轻钢结构，建筑方面突出的问题是防火设计。火灾危险性分类甲类的，防火设计更加重要。
6. On site assembly, mechanized construction, ensuring quality and progress, early production and quick results. The prominent issue in the application of light steel structures in the pharmaceutical industry is fire protection design. For fire hazard classification A, fire prevention design is more important.
