厂家解读确保门式脚手安全稳定的措施门式脚手架除了结构稳定、承载力大的特点，在使用时必须增加一些构造措施，才能增强门架的支撑能力，这也是门式脚手架能够做到安全不倒的诀窍。高度在4.5 m以上的高支模在施工前必须由施工单位编制专项技术方案。…

有时脚手架坯会出现分层问题，从而导致探伤不合。要预防这一缺陷，我们可以采取以下三点处理措施：(一)优化缓冷时间：优化脚手架板坯的缓冷工艺，主要针对堆垛温度和堆垛持续时间。轧制钢板厚度不大于80mm钢板热矫直后，在冷床停留时间不得超过5min。厚度大于80mm钢板可适当延长至10min，确保钢板成垛前温度控制在500℃以上。钢板厚度不大于50mm钢板缓冷时间在12h;厚度大于50mm的钢板缓冷时间24h，严禁提前拆垛精整。
Sometimes the stratification of square billet will occur, which will lead to incompatibility of flaw detection. To prevent this defect, we can take the following three measures: (1) Optimizing slow cooling time: optimizing slow cooling process of tube slab, mainly for stacking temperature and stacking duration. After hot straightening, the residence time in the cold bed should not exceed 5 minutes for the rolled steel plate whose thickness is not more than 80 mm. Thickness of steel plate over 80 mm can be appropriately extended to 10 minutes to ensure that the temperature of steel plate before stacking is controlled above 500 C. The slow cooling time of steel plate with thickness less than 50 mm is 12 hours; the slow cooling time of steel plate with thickness greater than 50 mm is 24 hours. It is strictly forbidden to disassemble and stack in advance.
(二)优化控制冷却
(2) Optimizing Controlled Cooling 脚手架板坯出现贝氏体一般是由于冷速过快造成的。当冷却速度降低至3-5℃/s时，钢板心部偏析带不再出现贝氏体组织，形成常规的珠光体组织。控制冷却优化后，板坯心部偏析带组织应力明显减少，因组织应力产生的微裂纹得到大大改善。
Bainite in square tube slab is usually caused by too fast cooling rate. When the cooling rate is reduced to 3-5 C/s, the bainite structure is no longer present in the segregation zone of the steel plate core, and the conventional pearlite structure is formed. After controlled cooling optimization, the microstructural stress of segregation zone in the center of slab decreases obviously, and the microcracks caused by microstructural stress are greatly improved.
(三)集中装炉制度
(3) Centralized charging system
在实际生产中轧制钢板的长及宽相差较大，在钢板缓冷时存在堆垛不整齐的情况，导致超宽板边部探伤检验不合格或是超长板头部探伤检验不合格。通过建立集中装炉制度，安排轧制钢板长、宽相近的合同集中装炉，保证后续钢板堆垛的整齐。必要时对脚手架板坯周边采用石棉布包裹，加强保温效果。
In actual production, the length and width of rolled steel plate are quite different. When the steel plate is slowly cooled, there is irregular stacking, which results in unqualified edge inspection or head inspection of ultra-wide plate. By establishing the centralized charging system, arranging the contract centralized charging of rolling steel plate with similar length and width to ensure the orderliness of subsequent stacking of steel plate. When necessary, asbestos cloth is used to wrap around the square tube slab to enhance the insulation effect.
