旋转扣件卸料平台的拆除

2017-04-07

           旋转扣件的施工工艺:
  (1)定位定距:根据构造要求量出内、外立杆距墙距离,并做好标记。用钢卷尺拉直,分出立杆位置,并用白灰点出立杆标记。垫板准确放在定位线上,垫板必须铺放平稳,不得悬空。
  (2)在搭设首层脚手架的过程中,沿每框架格内设一道斜支撑,待该部位脚手架与主体结构的连墙件可靠拉结后方可拆除。
  (3)当卸料平台操作层高出连墙件两步时,应采取临时稳定措施,直至连墙件搭设完毕后方可拆除。
  (4)落地卸料平台架体搭设,宜先立里排立杆,然后依次向外。每排立杆宜先立两头,再立中间的一根,互相看齐后再立中间部分各立杆。立杆接长时,应先立外排,后立内排。
  旋转扣件卸料平台的拆除:
  (1)架子拆除时应划分作业区,周围设围栏或竖立警戒标志,地面设有专人指挥,严禁非作业人员入内。
  (2)拆除的高处作业人员,必须戴安全帽,系安全带,扎裹脚,穿软底防滑鞋,拆下的材料,应用绳索拴住,利用滑轮徐徐下运,严禁抛掷,运至地面的材料应按指定地点,随拆随运,分类堆放,当天拆当天清,拆下的扣件或铁丝要集中回收处理。(3)拆除顺序应遵循由上而下,先搭后拆,后搭先拆的原则。即先拆脚手板、斜拉杆,后拆横杆、纵杆、立杆等,并按一步一清的原则依次进行,要严禁上下同时进行拆除作业。
  (4)拆立杆时,应先稳住立杆再拆开最后两个扣。
  (5)连墙点应随拆除进度逐层拆除,在拆架过程中,不得中途换人,如必须换人时,应将拆除情况交代清楚后方可离开。
  (6)拆除时要统一指挥,上下呼应,动作协调,当解开与另一人有关的结扣时,应先通知对方,以免坠落。
  (7)拆除时如附近有外电线路,要采取隔离措施。严禁架杆接触电线。
  (8)拆除时不应碰坏门窗、玻璃、落水管、房檐片、地下明沟等物品。
