摘要
某工程底板建筑面积64405m^(2),设计图纸要求本工程底板或楼板表面平整度,要求支持区偏差不大于4mm/2m、核心区偏差不大于2mm/2m。根据工程特点,在柱与柱之间不大于2m增设标高控制点,标高控制采用底板标高及平整度的控制装置,并采用人工搓平+机器收光施工方法。介绍了底板标高及平整度的控制装置的设计原理,详细介绍了底板收光的施工工艺。底板平整度检测数据显示,底板平整度满足设计要求。
The floor area of a certain project is 64405 m².The design drawings require the flatness of the floor or slab surface,and the deviation of the support area is not more than 4mm/2m,and the deviation of the core area is not more than 2mm/2m.According to the characteristics of the project,elevation control points shall be added no more than 2m between columns.The elevation control shall be carried out using a control device for the elevation and flatness of the bottom plate,and the construction method of manual leveling and machine finishing shall be adopted.The design principle of the control device for the elevation and flatness of the bottom plate was introduced,and the construction process of the bottom plate finishing was detailed.The flatness test data of the bottom plate shows that the flatness of the bottom plate meets the design requirements.
