原因剖析,混凝土施工时平整度不契合请求。压模时间过早、太晚及压模时力气不分歧招致部分混凝土下陷及纹理不清现象。在摆放模具时,模具与模具之间衔接不够严密;在压模时,模具呈现滑动的状况招致“双眼皮”现象。
预防措施: 依照混凝土施工标准请求停止施工,保证各项指标合格。 严厉控制压模时间及操作的平均性,由于操作者本身差别,在同一段落或作业面上尽量不要换手作业;压模成型的时间与现场气温、日照、风力、施工面积以及混凝土的凝结情况等要素有直接的关系,且定型模具花纹的深浅不同压模时间亦不相同。 依照模具的纹理按照次第镶嵌摆放施工,重锤夯击模具时坚持垂直击打,防止模具滑动。
Preventive measures: According to the concrete construction standard request to stop construction, to ensure that the indicators are qualified. Strictly control the time of pressing and the average of operation, because the operators themselves are different, try not to change hands on the same section or working surface; the time of pressing is directly related to the factors such as temperature, sunshine, wind, construction area and concrete setting, and the depth of the pattern of the stereotyping die varies with the time of pressing. According to the texture of the mould, the construction is arranged according to the order of mosaic. When ramming the mould with heavy hammer, the vertical strike is insisted to prevent the sliding of the mould.
