厂房的承重結构是建筑物的骨幹,对厂房的安全和耐久具有决定性意义。因此无論設計或施工,都应該把保証厂房承重結构的質量放到头等重要的地位。尤其是对于重型厂房来說,这一点更为重要。关于重型厂房承重結构的选型問題,有些地方大家的意見基本是一致的;但也有些地方是有分歧的。本文仅就其中几个較大的問題提出几点意見,同大家商榷。 1.平爐炼鋼車間及鑄鋼車間的溶化工部和浇注工部是否一定要用钢結构? 在这个問題上,不少人都認为只能用鋼結构。他們看到了这类車間的温度高,有重級制吊車,負荷大,跨度大,車間又高等因素,因而要求在选择結构类型时,应該慎重。当然慎重是对的;但他們另一方面却認为只有鋼結构才有优良的技术性能,才是坚固耐久
The load-bearing structure of the plant is the backbone of the building, which is decisive for the safety and durability of the plant. Therefore, regardless of design or construction, the quality of the load-bearing structure of the factory should be put to the top of the list. This is even more important for heavy-duty factories. With regard to the selection of load-bearing structures in heavy-duty factories, the opinions of everyone are basically the same in some places; but there are also differences in some places. This article only puts forward several opinions on several of the larger issues and discusses with everyone. 1. Is it necessary to use a steel structure for the dissolved chemical department and the casting department of an open hearth steelmaking plant and a cast steel plant? On this issue, many people think that only steel structures can be used. They saw the high temperature of such workshops, heavy-duty cranes, large loads, large spans, and high workshops. Therefore, they should be cautious when selecting structural types. Of course, it is prudent to be correct; but on the other hand, they believe that only steel structures with excellent technical performance are strong and durable.
