【正文】 應(yīng)提前通知業(yè)主在使用前完善。施工難點(diǎn)多：本工程由于 1結(jié)構(gòu)鋼柱高度達(dá) 55 米，因此需分段在現(xiàn)場(chǎng)設(shè)立胎架進(jìn)行現(xiàn)場(chǎng)拼接焊接，要求嚴(yán)格控制鋼柱焊接時(shí)的平直度和精確度。次要部位如屋面檁條、支撐、隅撐、角鋼腹桿件、拉條等材質(zhì)為 Q235B，其力學(xué)性能應(yīng)滿足《普通碳素結(jié)構(gòu)鋼》 （GB/T7002022）的相關(guān)規(guī)定。：本工程結(jié)構(gòu)為鋼結(jié)構(gòu)框架結(jié)構(gòu)形式，共 4 層，建筑面積 平方米，建筑高度為 米。1 / 110目 錄第一章 編制依據(jù)
