现浇混凝土楼板的尺寸偏差通常采用拉水平线检查和制作灰饼两种方式来控制,但这两种方法分别存在操作麻烦、精度不高、对作业面有影响以及耗时较长、易由于灰饼移位损坏而导致精度无法保证等弊端。通过工程实践,文章介绍了一种利用预制砂浆小柱控制现浇混凝土楼板尺寸偏差的新工艺。 The size deviation of the cast-in-place concrete floor is usually controlled by pulling the horizontal line to inspect and make the gray cake. However, the two methods respectively have operation troubles, low precision, impact on the work surface and long time-consuming, Dislocation of the cake caused by the failure to ensure accuracy and other defects. Through engineering practice, this paper introduces a new method of using precast mortar to control the size deviation of cast-in-place concrete floor.
