30，用平板振动器振捣密实，表面平整，并做好排水设施。（2）支架搭设盖梁悬臂部分支架采用60*60*120、立柱范围采用90*60*120。钢管下垫设10*12方木，并安放底托调整钢管高度，使支架与地面铺装层支架密贴，达到面受力，严禁形成点受力。图 4 满堂架法盖梁施工图拼立杆时要确保垂直度，防止立杆偏心受力。接头部位必须连接牢固。支架搭拼时应挂线以控制调平。拼装时根据实际情况立杆的相邻接头应梅花状错开。安装上托时注意旋出距离不得大于30。剪刀撑在立杆和横杆拼装好后进行安装，沿横桥向和顺桥向方向设置剪刀撑，剪刀撑从顶到底要连续，搭接头保证不小于60，接头卡不少于两个（或使用连接扣件），与水平横杆的夹角为4560，两剪刀撑不允许自相交，要求布在立杆两侧。剪刀撑与立杆和横杆每隔150 用扣件固定，整根使用扣件不得少于4精品w o r d 可编辑资料-第 7 页，共 28 页-文档编码:CK10J5A5J4D8 HD5P4A1R7S9 ZJ9O2Y10G7H4文档编码:CK10J5A5J4D8 HD5P4A1R7S9 ZJ9O2Y10G7H4文档编码:CK10J5A5J4D8 HD5P4A1R7S9 ZJ9O2Y10G7H4文档编码:CK10J5A5J4D8
