提高現澆混凝土樓板質量有妙招
1、對梁板鋼筋標高進行控制
1. Control the elevation of steel bar
在梁兩端暗柱上測設50cm標高控制線，施工過程中依據控制線進行梁鋼筋綁扎，并將交接部位用雙扎絲綁扎牢固，防止下滑。澆筑混凝土前，根據50cm控制線對綁好鋼筋進行復核，發現標高偏差大于5mm及時進行調整。
The 50cm elevation control line is set on the dark columns at both
ends of the beam. In the course of construction, the steel bars are
bandaged according to the control line, and the joint part is fasten
firmly with the double ligature wire to prevent the slide. Before the
concrete is poured, the steel bar is rechecked according to the 50cm
control line. It is found that the deviation of the height is greater
than 5mm, and the adjustment is made in time.
2、對結構板模板支設進行跟蹤檢查驗收
2. Follow up inspection and acceptance of structural board formwork.
支設結構板模板時，先在剪力墻墻上抄測出閉合的樓層結構1m標高控制線。結構板模板背楞、木方鋪設后，按1m標高控制線利用紅外五線儀檢查木方、背楞的平整度，并用絲杠調節，平整度偏差控制在3mm以內。然后鋪面板，模板間接縫嚴密、平整，與木方、背楞鐵釘釘牢無松動。用紅外五線儀對結構板面板進行驗收，每間板四角點及中點必檢，平整度偏差控制在3mm以內，合格后進行鋼筋綁扎。
When the formwork is supported, the closed floor structure 1m
elevation control line is first detected on the shear wall wall. After
laying the plate template and laying the wooden square, the flatness of
the wooden side and the back corrugated is checked by the infrared five
line instrument, and the flatness deviation is controlled within 3mm
according to the 1m elevation control line. Then the panels are laid up,
and the joints between the formwork are tight and smooth. The structure
plate panel is checked with infrared five wire instrument, each plate
must be checked at four corners and middle points. The evenness
deviation is controlled within 3mm, and the steel bar binding is carried
out after being qualified
