1 brick wall
(1) masonry cracks:
Mortar strength grade is l他鄉ow, the improper use of但新 mortar categories, such a答時s mixed mortar masonry wall with lime 長可mortar masonry or with lax雪習 than the master, to reduc快兒e the intensity街能 of the whole m影車asonry is poor, easy pre人土mature weathering, susong;
In the construction process of morta在制r walls is not dense, not full, 吧物or mistakes and the building m近技ethod of seam and seam, blind seam c湖年racks caused by air;
In the construction o影火f a scaffold, crudely made秒匠, hole wall pipe holes, embedd算但ed in the wall into the 雨明supporting hook at 微年the supports, the k微廠arma is not sealed up risks大裡.
(2) wall surface crack到生:
The mortar plasterin輛離g is too deep, the destruction of 國有the integrity of the foundati分鄉on layer or the construction of the e請腦mbedded wood block improper operatio好件n caused by the uneven thickn草計ess of the bottom or even from the des些分truction of the formation of the hidden也農 damage.
