砌体工程的施工工艺及措施 砌体工程的施工工艺及措施提要：砖砌体的转角处和交接处尽量同时砌筑，如在转角处砌筑确有困难时考虑留斜槎，斜槎底长不小于高度的三分之二，槎子必须平直、通顺；分段位置在变形缝 自 砌体工程的施工工艺及措施 砖墙的砌筑工艺:抄平、放线→立皮数杆→铺灰砌砖→修缝、清理等。 抄平、放线:为保证建筑物平面尺寸正确及各层标高的正确，砌筑前应认真抄平、放线，各楼层标高引至楼板边缘或墙上，先放出墙轴线，再根据轴线放出砌墙轮廓及门洞口位置。 砌体施工中做到无皮数杆不施工，皮数杆间距为15～20m，转角处均应设立，砌砖前应先对皮数杆进行预检。 墙体砌筑时严格按照施工操作规程及设计要求施工，做好技术交底，砌体用砖提前浇水湿润，严禁干砖上墙，以确保砌筑及粉刷质量。 砌筑砂浆采用重量配合比，计量准确，试块按规定留置。砂浆应随伴随用，水泥砂浆和水泥混合砂浆必须在拌成后3h和4h内使用完毕，隔夜砂浆不得使用。 水泥砖的尺寸符合要求，数量足够。 构造柱处墙体砌成凸凹槎，槎深为60mm，高度为30cm。从底部先退后进，并按要求设置拉结筋。 砖砌体的转角处和交接处尽量同时砌筑，如在转角处砌筑确有困难时考虑留斜槎，斜槎底长不小于高度的三分之二，槎子必须平直、通顺；分段位置在变形缝、门口、构造柱处；隔墙与墙交接处留斜槎确有困难时可留直槎，且为阳槎，并加设拉结筋，拉结筋的数量为120mm厚墙加根φ6钢筋，间距沿墙高不超过500mm，埋入深度从墙的留槎处算起大于500mm，外露长度大于500mm，末端成90°弯钩。接槎时，将接槎处的表面清理干净，浇水湿润，并填实砂浆，保证灰缝顺直。后砌隔墙顶应用立砖斜砌挤紧。 沉降缝两边的墙角应按直角要求砌筑。先砌的墙要把舌头灰刮尽，后砌的墙可采用缩口灰的方法。掉入沉降缝内的砂浆和杂物，应随时清除干净。 在操作过程中，要进行自检，如出现偏差，应随时纠正，严禁事后砸墙。 自 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.
