钢结构安装的作业条件有：
Operating conditions for steel structure installation include:
1.编制好钢结构安装施工组织设计。经审批后贯彻和执行，钢结构安装程序必须确保结构的稳定性和不导致永*性的变形。
1. Prepare the construction organization design for steel structure installation. After approval, the steel structure installation procedure must ensure the stability of the structure and not cause permanent deformation.
2.取得经监理单位、工程总承包的检查、安装支座或基础验收的合格资料。
2. Obtain the qualified data of the inspection, installation support or foundation acceptance by the supervision unit and the general contractor.
3.钢结构安装前应按照构件明细表核对进场的构件。查验质量证明书和设计更改文件;工厂顶装的大型构件在现场组装时，应根据预组装的合格记录进行，构件交工所必需的技术资料以及大型构件预装排版图应齐备，并注意以下几点。
3. Before the installation of steel structure, the mobilized components shall be checked according to the component list. Check the quality certificate and design change document; When assembling large components installed in the factory on site, they shall be carried out according to the qualification records of pre-assembly. The technical data necessary for the delivery of components and the pre-assembly layout of large components shall be complete, and the following points shall be noted.
①构件应符合设计要求和规范规定。对主要构件(柱子、吊车梁和屋架等)应进行复检。
① The components shall meet the design requirements and specifications. The main components (columns, crane beams, roof trusses, etc.) shall be rechecked.
②构件在运输和安装中应防止涂层损坏。
② The components shall be protected from coating damage during transportation and installation.
③钢结构安装前应清除附在表面的灰尘、冰雪、油污和泥土等杂物。
③ Before the installation of steel structure, dust, ice and snow, oil and dirt and other sundries attached to the surface shall be removed.
4.钢结构构件应按安装程序保证成套供应，现场堆放场地能满足现场拼装及顺序安装的需要，屋架分片总装，在现场进行拼配组装时准备拼装好工作台，构件分类堆放。刚度较大的构件可以铺垫木水平堆放，屋架宜立放，紧靠立柱，绑扎牢固。
4. The steel structure components shall be supplied in complete sets according to the installation procedures. The site stacking yard can meet the needs of site assembly and sequential installation. The roof truss shall be assembled in pieces. When assembling and assembling on site, the assembly workbench shall be prepared and the components shall be stacked in categories. Members with large rigidity can be stacked horizontally with bedding wood, and the roof truss should be placed vertically, close to the column, and firmly bound.
5.构件在工地制孔、组装、灯接和铆接以及涂层等的质童要求均应符合有关规定。
5. The quality requirements for hole making, assembly, light connection, riveting and coating of components on site shall comply with relevant regulations.
