对斜屋面渗漏原因进行了分析,认为斜屋面变坡交接处钢筋配置不足、波形瓦铺贴不实、施工缝位置留设不当、现浇钢筋混凝土板施工坍落度不当、施工方法不当等原因是产生渗漏的主要原因,并提出了设计时应考虑整个斜屋面板、板与梁之间相互变形及结构约束形式。屋面渗漏的隐患部位,除结构上增置钢筋网片外,还要采取模型板采用双面支模灌筑混凝土斜板,形瓦(以下简称波瓦)屋面正确施工等措施。
The reasons for the leakage of inclined roofs were analyzed, and it was considered that the rebar configuration at the transition site of the inclined roof was insufficient, the wave tile was unrealistically laid, the position of the construction joint was improperly set, the slump of the cast-in-place reinforced concrete slab construction was improper, and the construction method was improper. The reason is the main reason for the leakage, and it is proposed that the entire slanted roof panel, the mutual deformation between the plate and the beam, and the structural constraints should be considered in the design. For the hidden parts of the roof leakage, in addition to the construction of reinforcing steel nets on the structure, the model board shall be used for the construction of concrete sloping plates with double-sided molds, and the correct construction of roof tiles (hereinafter abbreviated as wave) shall be adopted.
