多单元的住宅工程纵横间隔多,转角处多。要使同一层、同一单元地面在同一设计水平面上,平整度达到验评标准,尤其要达到优质标准具有一定难度。现介绍控制住宅工程水泥地面水平度的方法。住宅工程的水泥地面施工有粘结层、找平层和水泥砂浆面层3道工序。施工时,冲好找平层标筋是保证地面水平度、平整度,满足设计及验评要求的关键。门框下端有一水平锯口线,它是地面标高的标志。在立门框 Multi-unit residential projects are more vertical and horizontal, with many corners. If the same floor and the same unit are on the same design level, the flatness will reach the assessment standard, and it will be difficult to achieve high quality standards. Now we introduce the method of controlling the level of cement ground in residential projects. The concrete floor construction of residential projects consists of three steps: adhesive layer, leveling layer and cement mortar surface layer. During construction, punching the screeds in the screed is the key to guarantee the levelness and flatness of the ground and meet the design and inspection requirements. There is a horizontal kerf line at the bottom of the door frame, which is a sign of the elevation of the ground. In the door frame
