近来,随着城乡住宅装饰热的兴起,室内地面较多地铺设地砖、大理石、花岗岩等块料,这些材料铺设后经过一年的冬夏交替,如果铺设方法不当,往往会出现不同程度的起拱、开裂等现象,而且在夏季特別明显。既影响使用功能,又影响美观。究其原因,主要在以下几个方面。 1.块料结合层与找平层粘结不牢固,经一段时间的振动,引起空鼓。 2.由于块料排布过于紧凑、密实,热胀冷缩吋,底层与面层膨胀性能不同,块料本身无法自由伸缩,只能往上部无约束方向起拱,从而因变形而开裂。
Recently, with the rise of residential and urban residential heat, the indoor floors are increasingly covered with blocks of floor tiles, marble, granite, etc. These materials are laid after one year of winter and summer alternates. If the laying method is improper, there will often be arches of varying degrees. , cracking and other phenomena, and particularly evident in the summer. Both affect the use of features, but also affect the appearance. The reason is mainly in the following aspects. 1. The bonding layer of the block material and the screeding layer are not firmly bonded and cause emptying after a period of vibration. 2. Due to the compact and dense arrangement of block materials, thermal expansion and contraction, and the difference in the expansion performance between the bottom layer and the surface layer, the block material itself cannot be flexibly stretched, and can only be arched in the upper unconstrained direction, and thus cracks due to deformation.
