建筑地面空鼓的回弹测试法

Rebound Test for Surface Layer Unglued from the Floor

建筑装饰装修、建筑地面工程是建筑工程中重要的分部工程,目前在工程完工后通过观察、小锤轻击的方法对面砖粘贴质量、抹灰层粘结质量进行检测。但是目测、敲击等常规检测手段主观随意性大、工作效率低,而且检测效果不佳。利用回弹法在测试材料抗压强度过程中,遇到气孔或空鼓时回弹值会异常低的原理,通过合理的测点布置和有效的缺陷判别,可以全面、准确、直观地检测出建筑地面、装饰工程空鼓缺陷的分布情况。

The constructional decoration and constructional flooring projects are the important parts in constructional engineering and currently the qualities of face tile attachment and plaster layer adhering are checked by means of visual observation and gentle knocking with small hammer after the end of project. However, the said conventional visual observation and knocking test methods are more in subjective randomness and low in efficiency to result in poor inspection effect. With the principle of the rebound value being abnormally quite low in case there are air holes or hollowing in the process of compressive strength test of materials with rebound method, the hollowing defect distributions in constructional flooring and architectural decoration engineering can be detected completely, accurately and visually by means of reasonable test point layout and effective defaults judgments.
