The main amounts of works please see the following table 1.1-1. It includes pipe rack between units of project, steel support frames for equipment, accessory steel structure of equipment & other little structural steel. All the main steel structures are made of H-shape columns and beams. They are connected by heavy hexagon steel bolts and nuts. 钢结构工程量一览表 表1.1-1序号项 目单位数 量备 注1设备框架、管廊结构吨49942设备平台、梯子吨7483高强螺栓吨774防腐吨40845防火吨910合 计吨5819框架、平台及螺栓Schedule of Amount of Steel Structure Works Table 1.1-1No.ItemUnitAmount Note1Steel support frame for equipment and pipe rackTons49942Platforms of equipment and stairsTons7483High-tensile bolts and nutsTons774Preservation Tons40845Fire preventionTons910 TotalTons5819Frame, Platform & Bolts钢结构安装工程的主要工作内容包括材料检验、构件预制与安装、构件防腐与防火施工以及焊缝无损检测等。The main works of structural steel installation include materials inspection, member prefabrication, member preservation and fire prevention and NDT of welding etc.本工程实行工厂化作业，钢结构预制将根据合同条件及、建设单位的要求全部在施工生产暂设的结构加工场区进行；安装施工时，根据结构柱基础移交进度情况，统筹安排钢结构预制安装进程，总体原则是：优先进行管廊结构的安装，后进行钢框架的安装，对妨碍大型设备运输、吊装的钢结构可依据现场进度情况适当推迟，以确保乙烯裂解装置总体进度计划实施。管廊结构的安装，拟利用50吨270吨等不同等级的吊车将预制合格的构件逐件吊装完成；设备框架的安装，如设计与安装条件许可，拟在其安装位置就近预制成片或箱形的单元结构，利用大型吊车整体安装。Factorial fabrication shall be taken in this project. All the prefabrication works of steel structure will be carried out at our steels structure fabrication workshop. The installation works of steel structure will be carried out according to the turning over condition of foundation. The prefabrication and installation works of steel structure will be given an overall consideration. The general principle is that first install pipe rack, then install steel frames. For structural steel that will get in the way of transport and lifting works of heavy duty equipment the installation works can be postponed according as the construction progress of site. We intend to use the cranes capacities from 50 tons through 270 tons to lift that prefabricated components. If it is permission by designing and installation conditions, for the installation of steel frames we propose to assemble them into one piece and lifted with a heavy duty crane.每道工序完成后应及时向后续工序如防腐、管道安装、设备安装及防火层施工等办理书面工序交接。After each process step finished, written handing over works shall be taken to the following process step in timely such as preservation, pipe installation, equipment installation and fire prevention etc.1.1.2 编制依据 Establishment Reference02CNSHY26SECCO121上海赛科石油化工有限公司乙烯装置安装工程施工标段招标文件及其答疑文件。Package I Tender Files of Installation Works of Ethylene Plant and clarification files of Shanghai SECCO Petrochemical Co.
