钢楼梯施工 施工顺序 Sequence of Construction 按照施工组织设计由下而上进行，顺序安装时要特别注意错误的累计所造成的质量问题或事故，在安装过程中经常性核对尺寸避免累计误差，确保安装质量。 The construction shall be started from bottom to top according to the construction organization’s design. Installation in order needs to pay special attention to quality problems or accidents caused by the accumulation of errors. The dimensions shall be checked regularly in installation to avoid accumulative error so as to ensure installation quality. 1. 安装顺序：安装吊装第一段钢柱-→装设一层外墙排山-→拉设安全防护网-→吊装二层钢梁-→踏步板安装-→二层平台楼承板安装-→安装吊装第二段钢柱-→装设二层外墙排山-→拉设安全防护网-→吊装三层钢梁-→二层踏步板安装-→三层平台楼承板安装-→以此类推-→→刷防火漆-→扶手安装→验收。 1. Installation sequence: erect the first section of steel column→ erect the external wall gable of the first floor→ put up safety fence → hoist the steel beam of the second floor → install treads → install the floor support plate of the second floor landing →erect the second section of steel column → erect the external wall gable of the second floor → put up safety fence → hoist the steel beam of the third floor → install treads of the second floor →install the floor support plate of the third floor landing → and so forth to roof installation→ apply fire-retardant paint →railings installation → acceptance. 2. 每一独立单元构件安装完后，应具有空间刚度和可靠稳定性。 2. Every independent unit member, after installed, shall have space rigidity and reliable stability. 安装和校正 Installation and Rectification （1）构件安装宜采用综合安装的方法施工。 (1) It is better to install members in a synthetic manner. （2）采用综合安装方法时，其结构必须能划分成若干独立体系活单元，每一体系（单元）的全部构件安装完后，均应具有足够的空间刚度和可靠的稳定性。 (2) Taking synthetic installation, their structure must be able to be divided into several independent systems (active units). Every system (unit) shall have adequate space rigidity and reliable stability when all their members are installed. （3）需要利用已安装的结构吊装其它构件和设备时，应征得设计单位的同意，同时应采取措施防止损坏结构。 (3) If it is necessary to make use of the installed structures to hoist other members and equipment, permission shall be asked from the design unit and measures s
