在高层住宅建筑中的厨房、卫生间使用倒槽板代替槽板,如处理不当,就有可能出现裂缝和漏水现象。重庆市某住宅小区1号楼(十九层)、5号楼(二十层)在厨房、卫生间大量使用倒槽板代替槽板。由于现今没有设计倒槽板的标准图集,一般套用钢筋混凝土槽板图集(川G211)倒置改用。例如,在1号楼中将正槽板CB3066和 CB3696中的①、③号筋位置互换并加大①号筋的直径(由φ12和φ14改为φ
In the kitchens and bathrooms of high-rise residential buildings, slotted plates are used instead of channel plates. If they are handled improperly, cracks and water leakage may occur. In Chongqing, a residential area of Building 1 (19th Floor) and Building 5 (20th Floor) use a large number of slotted plates instead of slotboards in the kitchens and bathrooms. Because there is no standard atlas of the design of the tilting plate, the general atlas of the reinforced concrete channel plate (Chuan G211) is generally inverted. For example, in Building 1, interchange the positions of No. 1 and No. 3 ribs in CB3066 and CB3696, and increase the diameter of No. 1 rib (change from φ12 and φ14 to φφ).
