2.2 production standard
door type scaffold in our country production and use are not long time,various research units develop scaffolding zichengtiji, each other is not universal, a variety of different specifications. some production factory imported products, the british size. door typescaffolding so far there is no unified design and product standards, the factory products of different specifications, quality is not consistent, not only to the construction unit and managementbrings very great difficulty, unfavorable popularization and application, but also to the building construction safety. so, should as soon as possible to organize the preparation and issuance of gatetype scaffold uniform standards. at present, the door type scaffold in standardization, the main problems, one is the factory scaffolding parts of inconsistent to the scaffold, the promotionapplication brings very big inconvenience; two is the major component of various size specifications. the world of gate type scaffold size range, has adopted the international units and two units ofmeasurement. such as a door frame width inch size is 1219mm, the international system of units for 1200mm, respectively 1829mm and 1830mm frame spacing. because of these different dimensions, so thatthe door frame can be general. and as the door frame height size of more than eight, a connecting pin spacing between the size also has a variety of, the cross braces specifications manyvarieties.

2.3施工安全
　　虽然扣件脚手架具有拆装灵活、运输方便、通用性强等特点。但是，这种脚手架安全保证较差，施工工效低，不能适应基本建设工程发展的需要，并存在以下几个方面问题。在施工工效方面，施工工效低，需要技术熟练的架子工，工人劳动强度较高等。在安全性能方面，每杆立杆容许载荷不超过10kn，安全保证较差，脚手架组装高度原则上不超过30m超过30m时，底层钢管需要用双根组装等。在经济效益方面，用钢量多，每1000m2墙面脚手架总用钢量为1617t，脚手架一次性投资小，但组装较费工，综合经济效果较差，施工使用费高于门式脚手架。
　　自上个世纪90年代以来，一些地区多次发生脚手架、模板倒塌重大事故，给国家和人民生命财产造成很大损失。为制止这类事故再度发生，建设部在1993年发布了“关于防止建筑施工模板倒塌事故的通知”，对如何防止脚手架、模板倒塌事故提出了要求，还特别强调今后如再造成模板倒塌，特别是造成一次死亡3人以上事故的，除追究直接责任者外，还应按照有关规定追究有关领导的责任，并对企业给予停止承包工程，降低资质等处罚。可是“通知”发布后，还有一些施工企业没有高度重视，脚手架、模板倒塌几乎每年都有发生，造成了重大的生命财产损失。脚手架的质量安全问题已经成为建筑施工过程中一个突出的安全问题。
