10、整场地，填补坑洞，和室内标高一致达到平整要求。3 扣件式钢管脚手架的搭设 施工用的满堂红钢管脚手架搭设的要求是:横平竖直,整齐清晰,图形一致，平竖通顺,连接牢固,受荷安全,有安全操作空间,不变形,不摇晃。4 满堂红钢管脚手架搭设的施工顺序:安立杆安扫地杆按横杆铺钢质跳板安上层立杆安上层横杆逐层只设到室内4层楼底板，首先在底部距地面100mm处设置一道扫地杆,以保持脚手架底部的整体性,底部的立柱应间隔交叉用不同长度的钢管,将相隔立柱的对接接头位于不同高度上,使立柱受荷的薄弱截面错开,满堂红脚手架搭设时先立立柱, 立柱与扫地杆采用直角扣件固定牢固，架设时考虑到室内大厅的跨度而设置成长方形环绕室内四
11、周。立柱每条隔距按照尺寸,立好柱后,架设大,小横杆,当第一步的大小横杆架设完毕后,做好固定件,以方便操作者上去架设第二步脚手架;同时在立柱之间的规定位置及时设置剪力撑,以防止脚手架纵向倾倒,剪力撑的搭设必须与架体的向上搭设同步进行。立柱接杆、接长应用对接扣件,不能采用旋转扣件;横杆与立柱连接采用直角扣件,剪力撑和斜撑与立杆和大横杆的连接应采用旋转扣件,剪力撑的纵向接长应采用旋转扣件,不能采用对接扣件,所有的扣件紧固要求用力矩板手实测达到4070N.m,在安装扣件时,所有的扣件的开口必须向外。(1) 在搭设满堂红脚手架时;每完成一步都要及时校正立柱的垂直度和横杆的标高和水平度,使脚手架的横距,纵
12、距上下始终保持一致。(2) 满堂红脚手架搭设完毕应进行验收,验收合格并办妥验收手续方可使用.七、满堂红钢管脚手架的安全检查措施每日进行一次，定期的维护保养，一般每月进行一次，1 检查脚手架的基础有无局部不均匀下沉，脚手架底部有无堆放杂物。2 检查脚手架的整体和局部的垂直偏差，特别要注意脚手架的转角处的垂直度，如发现垂直度有异常现象，应及时加固和消除隐患。3 各类扣件的涂油和紧固检查扣件时先检查扣件的外观，而后将扣件的螺栓逆时针方向松几牙螺纹，再涂油紧固螺栓至规定的力距范围。4 与建筑物连接的检查；检查连接件是否齐全完好，有无松动、移动。八、满堂红钢管脚手架的拆除满堂红钢管脚手架在拆除前必须做好
13、以下工作：1 对脚手架进行安全检查，确认脚手架不存在严重隐患如存在影响拆除脚手架安全隐患，应先对脚手架，进行整修和加固，以保证脚手架在拆除过程不发生危险。2 对参与脚手架，拆除的操作人员、管理人员和检查、监护人员进行安全、保护等措施的交底，交底的的内容应包括拆除范围，数量、时间和拆除顺序，方法。拆除的安全措施和警戒区域。交底要有记录，双方均应在交底书上签字。4 在拆除的脚手架周围,于坠落范围四周设置明显“禁止入内”的标志,并有专人监护，以保证在拆脚手架时无其它人员入内。上述这些工作经检查符合要求后,并确认建筑施工再也不需要用脚手架时,就可进行脚手架拆除。脚手架的拆除应从上往下,水平方向一步拆完
14、再拆下一步随着脚手架的向下拆除,对墙面的饰面,窗及其它墙面装饰及时做好清洁和保护工作,对脚手架的连接处饰面的补修应与脚手架的拆除同步进行,饰面补修经检查认定合格,做好清洁和保护工作后方可继续向下拆除脚手架。拆除脚手架应一步步进行,由上而下,一步一清地进行拆除。拆下的脚手架钢管,扣件及其它材料运到地面后,应及时清理,将合格的,需要整修后可重复使用的和应报废的加以区分,按规格堆放。对合格件应及时进行保养,保养后送仓库保管,以备今后使用。拆除脚手架时要遵守GB3608-83高处作业的有关规定,特别是按关于强风区高处作业,雨天高处作业和雷天高处作业的有关规定执行。每日拆除脚手架告一段落时，都要对尚未拆
15、除的脚物架的安全状况进行检查,还要对周围环境进行检查,如有异常情况应及时处理,确认一切均安全后方可离岗,不可疏忽大意,留有隐患。九、安全防护措施安全施工在施工方案中多处提及,对于脚手架有牢固的骨架,可靠的连接。稳妥的基底,并按正确的顺序搭设和拆除,这些均是保证安全的重要环节,除此之外,尚需重视在使用过程中出现的安全防护问题,并在各出入口及通道挂上安全标志。1 在施工期间应派专人定期和不定期检查脚手架的安全情况,做到无事故隐患,发现隐患及时处理。4 在搭建作业时应做好安全防护,作业人员必须戴安全帽,系安全带及穿胶底鞋。十一、文明施工1 施工现场按平面图堆放材料，材料要堆放整齐。2 施工现场要经常
16、保持整洁卫生，搭设后应当把余下的材料堆放整齐，杂物清理运走。4 在施工完成后要检查场地的杂乱情况，如有不符合安全、文明施工要求的要马上整改。（英文版 ） Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of comprehensive strictly strategic plan, implementation in accordance with the rule
