墙面抹灰出现开裂现象，有必要处理吗？

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

　　要看开裂的具体情况，很多情况下，抹灰层出现的裂纹是不需要处理的。

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

　　但是对于一些特殊情况下的裂纹，我们必须处理。所以我们首先应该分清墙体抹灰层上的裂纹有哪些，然后根据不同的类型去采取对应的处理裂纹的方法。

　　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.

　　下面给大家介绍墙面抹灰层裂缝的类型，并给大家制定相应的处理的方法。

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

　　抹灰层贯通性裂缝

　　所谓的贯通性的裂缝，就是指我们墙面抹灰层上出现的裂缝是非常规则均匀的裂缝。例如是水平裂缝，又或者是垂直裂缝。这类裂缝的宽度一般达到两三毫米，而深度几乎是整个墙体。也就是说，从这面墙已经裂透到另一面墙。

　　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

　　①两种不同墙体交接处受力收缩不同产生的裂缝。例如新砌筑的墙体和原先家里已有的老墙的接茬的部位出现的收缩裂缝。再就是由于在砌墙的时候没有按照要求设置拉结筋，或者没有做好缝隙的处理导致的。

　　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由于结构沉降导致的贯通性裂缝。这种裂缝一般是不太规则的，但是也是属于非常严重的贯通性裂缝。例如砖墙上出现了一些贯通性裂缝。

　　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顶板下部的裂缝。顶板下部的裂缝，都是砌墙的时候没有做好墙体上部的斜砌造成的。

　　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.

　　处理方法

　　Handling method

　　①首先要将裂缝部位进行剔凿。把表面的抹灰层切割掉，然后剔凿掉，露出里面的墙体。

　　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检查墙体缝隙的具体情况。常规的可以将缝隙内清理干净，向内部填塞微膨胀水泥，或者填微膨胀混凝土。

　　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当等填完以后并达到粘结强度之后，就可以在表面挂钢丝网进行抹灰。最后完成这些比较严重的贯通性裂缝的修复。

　　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.
