墻面抹灰出現開裂現象，有必要處理嗎？

　　Is it necessary to deal with the cracking phenomenon of wall plastering?

　　要看開裂的具體情況，很多情況下，抹灰層出現的裂紋是不需要處理的。

　　It depends on the specific situation of the cracking. In many cases, cracks in the plaster layer do not need to be treated.

　　但是對于一些特殊情況下的裂紋，我們必須處理。所以我們首先應該分清墻體抹灰層上的裂紋有哪些，然后根據不同的類型去采取對應的處理裂紋的方法。

　　But for some special cases of cracks, we must deal with them. So we should first distinguish which cracks are on the plaster layer of the wall, and then adopt corresponding methods to deal with the cracks according to different types.

　　下面給大家介紹墻面抹灰層裂縫的類型，并給大家制定相應的處理的方法。

　　Below, we will introduce the types of cracks in the wall plastering layer and develop corresponding treatment methods for everyone.

　　抹灰層貫通性裂縫

　　所謂的貫通性的裂縫，就是指我們墻面抹灰層上出現的裂縫是非常規則均勻的裂縫。例如是水平裂縫，又或者是垂直裂縫。這類裂縫的寬度一般達到兩三毫米，而深度幾乎是整個墻體。也就是說，從這面墻已經裂透到另一面墻。

　　The so-called through cracks refer to the very regular and uniform cracks that appear on the plaster layer of our wall. For example, horizontal cracks or vertical cracks. The width of such cracks generally reaches two or three millimeters, and the depth is almost the entire wall. That is to say, the wall has already cracked through to the other wall.

　　原因分析

　　Cause analysis

　　①兩種不同墻體交接處受力收縮不同產生的裂縫。例如新砌筑的墻體和原先家里已有的老墻的接茬的部位出現的收縮裂縫。再就是由于在砌墻的時候沒有按照要求設置拉結筋，或者沒有做好縫隙的處理導致的。

　　① Cracks caused by different stress and shrinkage at the junction of two different types of walls. For example, shrinkage cracks that appear at the junction of newly constructed walls and existing old walls in the home. Another reason is due to the failure to set up tie bars as required or to properly handle gaps during wall construction.

　　②由于結構沉降導致的貫通性裂縫。這種裂縫一般是不太規則的，但是也是屬于非常嚴重的貫通性裂縫。例如磚墻上出現了一些貫通性裂縫。

　　② Penetrating cracks caused by structural settlement. This type of crack is generally irregular, but it is also a very serious penetrating crack. For example, there are some penetrating cracks on the brick wall.

　　③頂板下部的裂縫。頂板下部的裂縫，都是砌墻的時候沒有做好墻體上部的斜砌造成的。

　　③ Cracks in the lower part of the roof. The cracks in the lower part of the roof are caused by the improper diagonal masonry of the upper part of the wall during masonry.

　　處理方法

　　Handling method

　　①首先要將裂縫部位進行剔鑿。把表面的抹灰層切割掉，然后剔鑿掉，露出里面的墻體。

　　① Firstly, the crack area needs to be chiseled. Cut off the surface plaster layer, then chisel it off to expose the inner wall.

　　②檢查墻體縫隙的具體情況。常規的可以將縫隙內清理干凈，向內部填塞微膨脹水泥，或者填微膨脹混凝土。

　　② Check the specific condition of the wall gaps. Normally, the gaps can be cleaned thoroughly and filled with micro expansion cement or micro expansion concrete.

　　③當等填完以后并達到粘結強度之后，就可以在表面掛鋼絲網進行抹灰。最后完成這些比較嚴重的貫通性裂縫的修復。

　　③ After filling and reaching the bonding strength, steel wire mesh can be hung on the surface for plastering. Finally, complete the repair of these severe through cracks.
