            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.

            3、制作混凝土預制塊,控制板厚及平整度
            3. Make concrete precast blocks, control the thickness and flatness of the concrete.

            根據結構板設計厚度,預制10cm*10cm混凝土塊,預制塊制作長度誤差0~2mm且振搗密實,端部預埋5cm自攻絲一枚,伸入預制塊3cm,養護不小于14天。使用時,將標高預制塊分別固定在板角距墻梁邊不大于30cm處,及板四角點幾何連線中心,每間板保證安置不少于5個預制塊且刮杠刮平需覆蓋兩個預制塊。澆筑混凝土時,按樓層短方向布設樓板虛鋪砼,使砼略高于控制塊,在砼振搗后,用2m刮杠沿砼澆筑方向依次刮平砼表面;刮平時,刮杠始終覆蓋2個預制塊控制塊,使砼面與控制塊頂部平齊。
            According to the design thickness of the structural plate, prefabricated 10cm*10cm concrete block, prefabricated block length error 0~2mm and vibrant compaction, the end of the pre embedded 5cm self tapping, into the precast block 3cm, maintenance not less than 14 days. In use, the high precast blocks are fixed at the edge of the plate corner wall not more than 30cm and the four corners of the plate. Each board ensures that no less than 5 precast blocks are placed and the scraping and leveling of the scraper needs to cover two prefabricated blocks. When the concrete is built, the concrete is laid on the floor in the short direction of the floor, so that the concrete is slightly higher than the control block. After the concrete is vibrated, the concrete is scraped along the concrete surface in the direction of concrete pouring along the direction of 2m. In peacetime, the scraping bar covers 2 precast block control blocks all the time, making the concrete surface and the top of the control block flat.
