混凝土楼地面一般采用打标高点、带线的方式收平,这样施工出来的楼地面标高和平整度合格率不是很理想。在一些电子厂房中,对楼地面的标高和平整度要求很严格,施工中采用一种精平做法,可显著提高混凝土楼地面的施工质量。对表面需要收光的楼地面,一般按以下6步施工。一、控制标高和大致扒平在混凝土卸料过程中,使用自动安平激光扫平仪控制标高(图1)。在混凝土施 Concrete floor generally mark the use of high ground, flat with a flat line, so the construction of the ground floor elevation and flatness pass rate is not very satisfactory. In some electronic factories, the floor of the building elevation and flatness requirements are very strict, the construction of a kind of Jingping practice can significantly improve the quality of construction of concrete floor. On the surface of the floor need to receive light, generally according to the following six steps of construction. First, the control of the elevation and the general level In concrete unloading process, the use of automatic Anping laser level control instrument elevation (Figure 1). In the concrete facilities
