楼面板在荷载和温度应力的反复作用下发生变形是必然的,而水泥砂浆、现浇水磨石等刚性楼面面层受变形影响必然导致裂缝出现。掌握了裂缝的规律,采用嵌玻璃条或铜条的方法,就可将裂缝有效地控制在嵌条的边缘,并使其不能“乱动乱窜”。根据我们的经验,实行这种方法的具体部位如下。 It is inevitable that the floor panel is deformed under the repeated action of load and temperature stress, and the rigid floor surface layer such as cement mortar, cast-in-place terrazzo, etc. will inevitably lead to cracks due to deformation. Having mastered the law of cracks, the method of inserting glass bars or copper bars can effectively control the cracks on the edges of the fillets and make them unable to “disrupt”. According to our experience, the specific parts of this method are as follows.
