→ remove the peripheral rail of platform (including steel wire mesh and thick net ) and move it to the location of radius change and then to reinstall the rail →remove the platform plank which is within the range of radius change and the out end ring beam →cut off the radius beam which is the length of radius change → install the steel wire mesh of rail and the safety net. 7.2 施工方法 Construction plans 7.2.1 在烟囱内衬、外部爬梯、信号平台、休息平台、航标涂料施工完毕后进行(提升架构造见图 1-1) 提升(装置)架拆除。 Remove the hoist (device) tower after completing the construction of chimney inner liner, outer climbing ladder, signal platform, rest platform and navigation marker coating (refer to the drawing 1-1 on the hoist tower structure). 7.2.1.1 模板拆除 Formwork removal 施工烟囱筒体到顶后, 即可拆除全部内外模板。 由于模板采用的是组合定型钢模板, 其单块重量轻 (仅 5.4kg) ,易于拆除,故以人工分块拆除,操作在内外吊架上层进行。拆除时先用小铁锤敲松卡扣,然后拿 住钢模板传至操作平台,再用吊蓝运至地面。拆除前,外吊架兜底网应拉紧箍在筒壁上,直至平台外钢圈拆 除前。卡扣用塑料桶、袋集中后利用吊笼运至地面。 Remove all the inside and outside formwork after the chimney barrel reaching the top. It is easy to remove the formwork due to adopting the assembled retaining formwork, and the weight of the single piece of formwork is light (only 5.4kg). So remove the formwork piece by piece through manual work on the upper layer of the inside and outside hanging bracket. Make the buckle loose through striking with small hammer prior to remove, and then hold the steel formwork to pass it to the operating platform, then transport it to the ground with basket. The safety net of outer suspension bracket should be tightened on the chimney wall before removing till the outer steel ring of platform is removed before. Collect buckles and put them into plastic bucket or bag, and then transport them to the ground with suspension cage. 7.2.1.2 吊架拆除 Removal of hanging bracket 内外吊架均系由扁钢-50×5 组成,其构造如图 3-1。拆除时先将吊架上端安全网移至辐射梁上,把吊 架全部罩住,再从筒壁一点开始,沿环向依次拆除吊架下层脚手板和吊架扁铁架,上层脚手板和扁铁架、三 角架,丝杆⑥可铺搭临时脚手板作为拆除吊架的站人操作点,拆除的脚手板、扁铁架、三角架均运到操作 平台,再用吊绳捆绑后用扒杆吊运至地面。
