项目摘要

This is Study on The Evaluation Method about Unevenness on Surface of Substratum and Finish for Coating and Covering Floors'. First, 9 substratum boards each having 12 holes with different size(depth and diameter) as unevenness of substratum were coated with 3 kind of coating floors materials in 3 kinds of thickness. Second, the depth(or height) of each surface unevenness grown on coating floors were measured and the relative between depth and size of holes of substratum were discussed. Third, an allowable limit of unevenness of substratum to make surface of coating floors even was established as an example. Forth, I examined correlation between the grades of unevenness from viewpoint of vertical acceleration on casters which had various specifications (weight, diameter of wheel, running rate and solidness of wheel), and showed the possibility of ranking unevenness hierarchically by the acceleration and the necessity of considering not only unevenness but also solidness of floors when we evaluate unevenness of floors. Fifth, I investigated the relationship between defects of substratum concrete floor and impropriety of floors, and investigated the relationship between the impropriety in the construction of substratum concrete floor and defects on substratum concrete floor surfaces, especially unevenness, insufficiency of strength of surfaces and rain marks. Finally, we experimented with verifying defects caused by the impropriety, and confirmed and pointed out the proper importance of.the planning and management in the construction.

这是关于涂层和覆盖地板的基层和面漆表面不平整度评价方法的研究。首先，将9块基底板各具有12个不同尺寸(深度和直径)的孔作为基底的不均匀性，以3种厚度涂敷3种涂层地板材料。其次，测量了涂层地板上生长的每个表面凹凸的深度（或高度），并讨论了基底孔的深度和尺寸之间的相对关系。第三，举例确定了使涂装地坪表面平整的基材不平整度的允许限度。第四，我从不同规格（重量、车轮直径、运行速度和车轮坚固性）的脚轮的垂直加速度的角度研究了不均匀度等级之间的相关性，并表明了根据加速度对不均匀度进行分级的可能性和必要性。当我们评估地板的不平整度时，不仅要考虑不平整度，还要考虑地板的坚固性。五、调查了底层混凝土楼板缺陷与地坪不当的关系，调查了底层混凝土楼板施工不当与底层混凝土楼板表面缺陷，特别是不平整、表面强度不足、雨痕的关系。。最后，我们通过实验验证了不当造成的缺陷，并确认并指出了规划和管理在施工中的应有的重要性。
