Cold region roof rigid protective layer separation construction method
The invention relates to the technical field of roof construction, in particular to a cold region roof rigid protective layer separation construction method. Comprising the following steps that S1, typesetting, parting and paying-off are conducted on a roof according to unit modules; s2, square steel is fixed and pre-buried by mortar one day before the waterproof protection layer is lifted by a parting seam, 300 mm inwards, of the parapet wall; s3, 90-degree arc angles are formed between the parapet wall and a waterproof protection layer in the horizontal direction and between the roof smoke air duct and the waterproof protection layer in the horizontal direction; s4, square steel is pre-buried in the whole roof so that the roof can be divided into a plurality of unit modules, and concrete pouring construction adopts a one-by-one construction scheme for pouring; and S5, the square steel is taken out after maintenance is conducted for 7 days, garbage in seams is cleared away, and factice is filled for sealing. According to the construction method, the influence of frost heaving is reduced by using small-area unit modules, square steel is used as a separation joint to ensure that the square steel is straight, the phenomena of dry shrinkage and falling of peeling, dusting and cracking glue are avoided, and pouring is carried out through a construction scheme one by one, so that early cracks of concrete are effectively controlled.
本发明涉及屋面施工技术领域，具体是一种寒冷地区屋面刚性保护层分隔施工方法。包括以下步骤：S1：对屋面按照单元模块进行排版分缝放线；S2：女儿墙向内300mm的分缝采用方钢在防水保护层上提前一天采用砂浆固定预埋；S3：女儿墙和出屋面烟风道与水平方向的防水保护层做90°弧角；S4：屋面整体预埋方钢使其分隔成若干个单元模块，混凝土浇筑的施工采用隔一步一的施工方案进行浇筑；S5：养护7天之后取出方钢，缝内垃圾清除干净，填充油膏密封。利用小面积的单元模块，减少冻胀影响，并利用方钢作为分隔缝使其保证顺直，避免起皮起砂开裂缝胶干缩、脱落的现象，并通过隔一步一的施工方案进行浇筑，有效控制混凝土早期裂缝。
