哪些施工操作會導致宝盈娱乐官网墻體抹灰空鼓、開裂?
Which construction operations will cause air block wall plastering, cracking and cracking?
1、砌塊含水率控制不當,加氣混凝土砌塊吸水慢,沒有提前澆水濕潤。
1, improper control of moisture content of block, aerated concrete block slowly absorbing water, without watering in advance.
2、砌體灰縫飽滿度達不到規范要求,灰縫不密實或有空頭縫。
2, masonry ash joint plumpness can not meet the specification requirements, the seam is not dense or empty joints.
3、墻面凹凸不平過大,導致抹灰層過厚,易出現開裂、空鼓。
3, the uneven surface of the wall is too large, resulting in too thick plastering layer, prone to cracking and hollowing.
4、加氣混凝土砌塊與柱、梁、板連接處未按設計要求嵌填密實,未采取加強措施。
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、砌體墻面浮塵、魚鱗狀酥松物未清理干凈。
5. The floating dust and fish scales of the masonry walls are not cleaned up.
6、抹灰不分層進行,或兩層間隔時間太短。
6, plastering is not layered, or the two interval is too short.

8、施工工序把控不嚴,如基層甩漿、拉毛及后期養護不到位。
8, the construction process to control lax, such as grass roots slurry, hair and later maintenance is not in place.
9、結構構件(柱、梁、板)與砌塊間的連接、填塞做法不明確,沒有適當的加強構造措施。因鋼筋混凝土與加氣混凝土砌塊的溫、濕度變形不一致而造成開裂。
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.
