立柱工程施工技术交底.doc

1、施工前由测量班将立柱中心点在系梁上进行放样。
2、将系梁顶面与立柱连接部分凿毛，以清除混凝土表面浮浆。
3、将立柱模板表面打磨干净后均匀的涂抹一层脱模剂，用吊车等吊装设备
将涂抹好脱模剂的模板安装好，立模时用垂球校核模板的垂直度，模板之间的螺
栓必须全部拧紧。
4、检查模板的中心，模板中心应与柱中心重合，用4 个地锚将模板固定好，
地锚与缆绳用紧线器拉紧，用垫块将钢筋笼固定好，保证钢筋笼中心与柱中心重
合。
5、混凝土灌注时串筒下口距离混凝土面不得超过2m，混凝土灌注每层不得
超过50cm，浇注一层，捣固一层。
6、捣固时禁止将捣固器悬挂在钢筋或模板上，混凝土捣固时移动距离不得
超振动棒作业半径的1.5 倍，捣固棒距离模板不得小于15cm，捣固必须达到混
凝土表面泛浆均匀，不再大量冒泡，不再下沉为止。1, pre-construction the center column from the measurement of class will be conducted in the Department of beam loft.
2, tie beam and column connection part of the top surface of chiseling to remove the concrete surface floating pulp.
3 column template will clean and polish the surface of the coating layer even after the release agent, used cranes and other lifting equipment
Apply release agent will be installed templates, vertical mode when the check ball with a vertical verticality template, the template spiral between
Bolt must be completely tightened.
4, check the center of the template, the template center to be coincident with the center column with four to securely anchor the template,
Anchorage, and cable tension device with a tight line, with the pads securely to reinforcement cage to ensure the reinforcement cage center and the center column re-
Co.
5, the pouring of concrete under the mouth when the tube string from the concrete surface shall not exceed 2m, not the pouring of concrete on each floor
More than 50cm, cast layer, tamping layer.
6, tamping tamping device when the ban will be suspended from the bar or the template, moving from concrete when no tamping
Super vibrator operating radius of 1.5 times the distance from the template tamping rods shall not be less than 15cm, tamping must be mixed
Pan-uniform surface of concrete slurry, not a lot of bubbling, not sink so far.
