目前,石砌体墙面勾缝种类很多,有凸缝、凹缝、平缝和假缝。多数施工单位采用凸缝,有的为了美观勾假缝,一般做法是在墙体砌完后统一勾缝,但这样做缝内很难清理干净,勾缝砂浆与砌体砂浆结合不牢,直接影响砌体的质量。 At present, there are many types of joints in stone masonry walls, including convex joints, concave joints, flat joints and false joints. Most construction units use convex seams, and some use artificial hooks for the purpose of appearance. The general practice is to align the joints after the walls are finished. However, it is difficult to clean the joints in the joints. The joints between the joint mortar and the masonry mortar are not strong and direct. Affect the quality of masonry.
