            現澆混凝土樓地面一次澆筑方法操控
            混凝土振搗
            Vibration of concrete
            靠近邊、角處可先使用插入式振動器進行振搗,采用快插慢拔方式,按照成行或成列依次進行,并注意控制移動間距不大于振動器作用半徑的1.5倍。每個振搗點的持續時間,應以入?;炷镣V瓜鲁敛辉倜皻馀?,并泛出水泥砂漿為準,不宜過振。
            Inserted vibrators can be used for vibration tamping near edges and corners. Fast insertion and slow pull mode is adopted, which is arranged in rows or in rows. Attention should be paid to controlling the moving distance not more than 1.5 times of the radius of the vibrator. The duration of each tamping point should be based on the stop of sinking and no bubbles in the concrete, and the outflow of cement mortar. It is not appropriate to overshoot.
            混凝土抹光或拉細毛
            Finishing or polishing of concrete
            混凝土經提漿操作后,在終凝前用抹光機進行機械抹光,根據現場情況從一端向另一端按序進行,邊角及局部機械無法處理的部位使用人工跟隨機械搓毛、壓光。施工過程中,注意表面有凹坑或石子凸出時要及時鏟毛、剔除補漿修整,同時控制好標高和整體平整度,隨時采用2m靠尺進行檢查。
            After pulping operation, the concrete is mechanically polished with a polishing machine before final setting. According to the site situation, the polishing is carried out sequentially from one end to the other. Artificial and random mechanical rubbing and calendering are used in the corners and parts that cannot be handled by local machinery. During the construction process, attention should be paid to timely shoveling and grouting when there are pits or stone protrusions on the surface, while controlling the elevation and overall smoothness, and inspecting with 2m ruler at any time.
            拆模及養護
            Demoulding and Maintenance
            待混凝土地面抹光,混凝土拆模后不掉角時(混凝土達到終凝后),即可拆除槽鋼模板,將模板清理干凈備用。整個施工流程完成后的12h內進行澆水養護,夏季施工時需要增加澆水次數,已保持混凝土表面濕潤,而冬季施工應采取相應的保溫防凍措施。整個養護周期不少于7d,有抗滲要求的混凝土不能少于14d。
            When the surface of concrete is polished and the corner of concrete is not removed after removing the formwork (after the concrete reaches the final setting), the channel steel formwork can be removed and the formwork can be cleaned up for reserve. The whole construction process should be watered within 12 hours after completion. The number of times of watering should be increased during summer construction to keep the surface of concrete wet. In winter construction, the corresponding measures of thermal insulation and frost prevention should be taken. The whole curing period should not be less than 7 days, and the concrete with impermeability requirements should not be less than 14 days.
            成品保護
            Finished product protection
            混凝土樓地面施工過程中要注意對其他專業設備的保護,如埋設在混凝土內的管線不得隨意移位,地漏內不得堵塞砂漿等。地面施工完后,養護期內嚴禁進入踩踏。在已完工的混凝土面上進行油漆、電氣、暖衛專業工序時,注意不要碰壞面層,油漆、漿活不要污染面層,須采取鋪設彩條布等防護措施。如果先做地面,后進行地面抹灰時,要特別注意對地面進行覆蓋,并嚴禁在地面上儲存和拌制砂漿。
            During the construction of concrete floor, attention should be paid to the protection of other professional equipment, such as pipelines buried in concrete should not be shifted at will, and mortar should not be blocked in floor leakage. After the ground construction is completed, trampling is strictly www.diandongmenc.net.cnwww.chongyajiann.com.cnwww.xinzhouyanglao.cnprohibited during the www.diandongmenc.com.cnwww.chongyajiann.cnwww.yanglaoyuanc.com.cnmaintenance period. In the process of painting, electrical, heating and sanitation on the completed concrete surface, attention should be paid to not touch the surface layer, paint and paste should not pollute the surface layer, and protective measures such as laying colored stripes should be taken. If the ground is first made and then plastered, special attention should be paid to covering the ground, and it is strictly forbidden to store and mix mortar on the ground.
