房子最边上角落的外墙砖从底到顶有小裂缝

beanball

两层楼的房子，房子最边上角落的外墙砖从底到顶有小裂缝，隔一层每块全砖都裂成一半，但裂缝很小，不过从底到两层顶都是这样。为啥每隔一层，是因为每隔一层都有一块本来是半砖和全转的水泥接缝，因为接缝本来就是缝隙，所以不需要裂了。

想问一下懂建筑的朋友，这种情况是小问题还是大问题，需要修吗？或者能修吗？

裡面網友 tony 1851說得是正解

It's cause by expansion of the brickwork. This can result from 2 causes; 1. thermal expansion of a long stretch of brickwork, particularly south-facing, or 2. initial expansion of the bricks soon after construction (bricks are bone dry when they come out of the kiln and if they are built in soon after manufacture, they gradually take up atmoshpheric water which causes them to expand slightly).
Whichever the cause, something has to give, and you frequently see the vertical crack at the corner, particularly where there's a short return as you have. It's almost a text-book case of the symptom, and that fact that it doesn't extend below the dpc bears this out.

大概率是地基不均匀下沉。

原则上，纵向裂缝宽度小于1mm，基本问题不大，继续观察。

如果是单砖房就没有大问题

楼主给出的信息都不完整。。。。如果是新房，需要保持观察。如果是已经裂了十年以上的旧房，大机率是不会再发生问题了，补了把墙面一刷，啥事都解决了。

应该和这个类似，好像里面讲了好多种情况，请问有大问题吗？
还有这个裂缝在外墙，算承重墙吗？

不是什麼大問題.....不用擔心
應該是侧向內應力的均衡拉伸而不是承載軸向的剪力破壞或是沈陷問題
即或是承重牆體,只要能將應力正常傳遞至地樑，也不至於破壞整體結構
一般就只是持續觀測
只要裂紋不持續擴大成裂隙裂縫，或是裂張方向往橫向及斜向發展(尤其是斜向)，就不須理會

新房就是地基沉降，观察一下
旧房就没事了，反正几十年都住过了，没事????️
