清水砖墙一般都要勾缝。勾缝用的工具主要有长,短镏子和托灰板,托灰板端头要钉上薄钢板,最好用刚度大一些、有弹性的矽钢片,伸出6毫米。勾缝时,将板端搭在砖棱上,既方便操作,又能防止砂浆散落污染墙面。镏子应统一加工制作,断面要方正,可以做8毫米、10毫米两种,长 Clear water bricks are generally pointing. The tools used for grooving are mainly long, short rakes, and ash boards. The top of the ash board is to be nailed with a thin steel plate. It is better to use a high rigidity, elastic steel sheet with a length of 6 mm. When hooking, the end of the board is placed on the brick edge, which is convenient for operation and can prevent the mortar from scattering and contaminating the wall surface. The dumplings should be processed in a unified manner. The section should be squared and can be made of 8 mm and 10 mm long.
