In the case that the limited floor space can not meet the requirements of modern industrial production, many enterprises choose to build multi-storey steel structure workshops. But most of them are only built to 2-3 layers. The advantage of doing so is to integrate a coherent production relationship and make full use of the advantages of three-dimensional space. Unlike single-layer steel structure workshop, which occupies most of the ground area, it can save a lot of building area.

今天，我们来说说多层钢结构厂房的施工流程，，无论是高层还是单层，在施工前都要制定出工艺流程图，确定构件的安装顺序，分区段施工。钢结构厂房施工自然离不开起重机，无论单层或多层。

Today, let's talk about the construction process of multi-storey steel structure workshop. First of all, whether it is a high-rise or a single-layer building, before construction, we must first develop a process flow chart, determine the installation sequence of components, and construct in sections. The construction of steel structure workshop is naturally inseparable from the crane, no matter single or multi-layer.

所以，其次需要注意的是，起重机不可以超负荷作业，在吊装能力允许的情况下，可以再地面完成的组装工作，我们要尽可能的避免在高空作业。

Therefore, the second thing we need to pay attention to is that the crane can not be overloaded. When the lifting capacity allows, the assembly work can be completed on the ground. We need to avoid working at heights as much as possible.

钢结构厂房安装前，要根据建筑物的结构形式和现场的施工条件来划分安装流水段。安装流程应以从中部对称地向四周发展，竖向根据工艺流程制定焊接顺序。一节柱的各层梁安装完后，要立即安装楼梯以及楼承板，楼承板上的对房屋不能超过其承载。进行楼承板上的混凝土施工和构件的安装。

Before the installation of the steel structure workshop, the installation flow section shall be divided according to the structural form of the building and the site construction conditions. The installation process shall be developed symmetrically from the middle to the surrounding, and the welding sequence shall be established vertically according to the process flow. After the installation of each floor beam of a section of column, the stairs and floor bearing plates shall be installed immediately, and the load on the floor bearing plates shall not exceed the load of the house. Finally, the concrete construction and component installation on the floor bearing plate are carried out.
