【文章內(nèi)容簡介】 surface and pipe coil assembly works and flue/air ducting fabricating asembly works. b. 50t 汽車吊負責(zé)現(xiàn)場設(shè)備卸車倒運等工作。 . b. Truck crane of 50t shall be employed in equipments unloading in site. 4 置在鍋爐 0m， 輔助進行爐膛內(nèi)管排及 小件 的吊裝。 c . winch shall be arranged in 0m, assisting furnace internals lifting and the lifting of some samll units. d. 勞辛格負責(zé)汽包吊裝工作。 Standjack system will be used in steam drum listing works. (5) 施工電梯布置 service lift arrangment 為方便鍋爐施工，在爐 一 側(cè) 布置一施工電梯。 Sservice lifts shall be arranged in each side of the boiler. 2 鍋爐本體鋼架安裝 Boiler steel structure erection 鍋爐鋼結(jié)構(gòu)由頂板、柱和梁、垂直支撐、水平支撐等部件組成，頂板由主梁、次梁和小梁組成一個堅固的梁格，其四周有水平支撐，主梁端有垂直支撐。 Boiler steel structure consists of roof, column, girder, vertical and lateral supporting, while roof prising of girder, secondary beam, trabecula and forming a firm box. 鋼架內(nèi)側(cè)柱為主要承重鋼柱，外側(cè)副柱則通過梁、水平支撐與內(nèi)側(cè)柱相連，以增加鋼架的整體穩(wěn)定性。鋼結(jié)構(gòu)從前至后共有 6 排 。 鍋爐鋼架的連接，采用高強螺栓和焊接相結(jié)合的方式，頂板和主梁與次梁之間，柱和梁之間，垂直支撐、水平支撐之間采用扭剪型高強螺栓連接，其余構(gòu)件間采用焊接連接。 Internal pillars of the structure are designed for bearing, while the external pillars are designed to reinforce the entire stability of structure by connecting with girders, lateral supporting and internal pillars. There are 6 rows. Bolt and welding are employed in the connection of structure. 吊裝方案 Hoisting plans 主吊機械選用一臺 FZQ2020 圓桶吊，一臺 CC1400 履帶吊為附吊機械，圓筒吊布置于鍋爐爐左 K、 L 間距鍋爐本體外側(cè)柱中心線 5 米處， CC1400 履帶吊布置于爐的另一側(cè)。鋼架各段本著由爐前至爐后、先主柱后輔柱原則分段吊裝，即安裝一段找正一段，驗收本段鋼架后對高強螺栓進行終緊。鋼架安裝過程中相應(yīng)段平臺、樓梯、欄桿隨之安裝。 Main hoisting plants prise of an FZQ2020 cylindrical crane and CC1400 crawler crane (as auxiliary hoisting plants), the cylindrical crane shall be arranged at left side of boiller
