立柱工程施工技術(shù)交底.doc

1、施工前由測(cè)量班將立柱中心點(diǎn)在系梁上進(jìn)行放樣。
2、將系梁頂面與立柱連接部分鑿毛，以清除混凝土表面浮漿。
3、將立柱模板表面打磨干凈后均勻的涂抹一層脫模劑，用吊車等吊裝設(shè)備
將涂抹好脫模劑的模板安裝好，立模時(shí)用垂球校核模板的垂直度，模板之間的螺
栓必須全部擰緊。
4、檢查模板的中心，模板中心應(yīng)與柱中心重合，用4 個(gè)地錨將模板固定好，
地錨與纜繩用緊線器拉緊，用墊塊將鋼筋籠固定好，保證鋼筋籠中心與柱中心重
合。
5、混凝土灌注時(shí)串筒下口距離混凝土面不得超過2m，混凝土灌注每層不得
超過50cm，澆注一層，搗固一層。
6、搗固時(shí)禁止將搗固器懸掛在鋼筋或模板上，混凝土搗固時(shí)移動(dòng)距離不得
超振動(dòng)棒作業(yè)半徑的1.5 倍，搗固棒距離模板不得小于15cm，搗固必須達(dá)到混
凝土表面泛漿均勻，不再大量冒泡，不再下沉為止。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.
