现浇混凝土楼板顶棚（天花）抹灰抹纸筋灰工艺 现浇混凝土楼板顶棚（天花）抹灰抹纸筋灰工艺提要：根据墙柱上弹出的标高基准墨线，用粉线在顶板下100mm的四周墙面上弹出一条水平线，作为顶板抹灰的水平控制线。对于面积较大的楼盖顶或质量要求较高的顶棚 源自于建筑资料 现浇混凝土楼板顶棚（天花）抹灰抹纸筋灰工艺 一、施工准备 1、材料：与墙面抹纸筋灰相同。 2、作业条件 ⑴在墙面和梁侧面弹上标高基准墨线，连续梁底应设通长墨线。 ⑵根据室内高度和抹灰现场的具体情况，提前搭好操作用的脚手架，脚手架挢板面距顶板底高度适中（约为左右）。 ⑶将混凝土顶板底表面凸出部分凿平，对蜂窝、麻面、露筋、漏振等处应凿到实处，用1:2水泥砂浆分层抹平，把外露钢筋头和铅丝头等清除掉。 ⑷抹灰前一天浇水湿润基体。 二、工艺流程 基层处理→弹水平基准线→润湿基层→刷水泥浆→抹底层砂浆→抹纸筋灰面层 三、操作工艺 1、基层处理：对采用钢模板施工的板底凿毛，并用钢丝刷满刷一遍，再浇水湿润。 2、根据墙柱上弹出的标高基准墨线，用粉线在顶板下100mm的四周墙面上弹出一条水平线，作为顶板抹灰的水平控制线。对于面积较大的楼盖顶或质量要求较高的顶棚，宜通线设置灰饼。 3、抹底灰：在顶板混凝湿润的情况下，先刷素水泥浆一道，随刷随打底，打底采用1:1:6水泥混合砂浆。对顶板对顶板凹度较大的部位，先大致找平并压实，待其干后，再抹大面底层灰，其厚度每遍不宜超过8mm。操作时需用力抹压，然后用压尺刮抹顺平，再用木磨板磨平，要求平整稍毛，不必光滑，但不得过于粗糙，不许有凹陷深痕。 4、抹罩面灰：待底灰约六、七成干时，即可抹面层纸筋灰。如停歇时间长，底层过分干燥则应用水润湿。涂抹时先分两遍抹平，压实，其厚度不应大于2mm。 待面层稍干，“收身”时（即经过铁抹子压磨灰浆表层不会变为糊状时）要及时压光，不得有匙痕、气泡、接缝不平等现象。天花板与墙边或梁边相交的阴角应成一条水平直线，梁端与墙面，梁边相交处应成垂直线。 源自于建筑资料 Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness. Teach everyone, service education and management education, and school moral education work must be with family education and community education closely together, to form a concerted pattern, and strive to create a good atmosphere for education, and to promote the all-round development of students, to establish a scientific moral education full of vigor the For long-term mechanism.Two, the goal of moral education:To guide the students to form the correct world outlook, outlook on life, values, to cultivate students un
