哪些施工操作会导致加气块墙体抹灰空鼓、开裂?
Which construction operations will cause air block wall plastering, cracking and cracking?
1、砌块含水率控制不当,加气混凝土砌块吸水慢,没有提前浇水湿润。
1, improper control of moisture content of block, aerated concrete block slowly absorbing water, without watering in advance.
2、砌体灰缝饱满度达不到规范要求,灰缝不密实或有空头缝。
2, masonry ash joint plumpness can not meet the specification requirements, the seam is not dense or empty joints.
3、墙面凹凸不平过大,导致抹灰层过厚,易出现开裂、空鼓。
3, the uneven surface of the wall is too large, resulting in too thick plastering layer, prone to cracking and hollowing.
4、加气混凝土砌块与柱、梁、板连接处未按设计要求嵌填密实,未采取加强措施。
4. Aerated concrete blocks and columns, beams and plates are not filled with dense design according to the design requirements, and no reinforcement measures have been taken.
5、砌体墙面浮尘、鱼鳞状酥松物未清理干净。
5. The floating dust and fish scales of the masonry walls are not cleaned up.
6、抹灰不分层进行,或两层间隔时间太短。
6, plastering is not layered, or the two interval is too short.
7、门窗框与加气混凝土砌块墙体连接不牢。
7, door and window frame and aerated concrete block wall connection is not firm.
8、施工工序把控不严,如基层甩浆、拉毛及后期养护不到位。
8, the construction process to control lax, such as grass roots slurry, hair and later maintenance is not in place.
9、结构构件(柱、梁、板)与砌块间的连接、填塞做法不明确,没有适当的加强构造措施。因钢筋混凝土与加气混凝土砌块的温、湿度变形不一致而造成开裂。
9. The connection and packing of structural members (columns, beams, boards) and blocks are not clear, and there is no proper reinforcement measures. Because of the inconsistency between temperature and humidity of reinforced concrete and aerated concrete blocks, cracks are caused.
