在当前,现浇钢筋混凝土结构越来越多,楼板超厚现象也时有发生。我单位承建施工的某高层公寓,在施工开始时,也发生过楼板超厚的现象,这样不仅影响日后的装修,也给结构本身留下隐患。如卫生间地坪、走道、楼梯口,按有关规定要求应比起居室低10～20毫米,如果施工中不注意,剔凿超厚的混凝土时,容易把钢筋凿出来,露出表面,破坏楼板钢筋的可护层,造成以上问题的原因是:1.设计时没有考虑建筑使用功能的要求及建筑地坪之间的高差,未从结构上反映出来。
At present, there are more and more cast-in-place reinforced concrete structures, and the phenomenon of overthickness of floor slabs also occurs from time to time. The high-rise apartment that our company undertook to construct and construct, when the construction began, also happened to have a phenomenon of excessive thickness of the floor slab, which not only affected the decoration of the future, but also left hidden dangers to the structure itself. Such as bathroom floor, walkway, stairway, according to the relevant provisions of the requirements should be lower than the living room 10 to 20 mm, if not pay attention to the construction, picking ultra-thick concrete, it is easy to chisel out the steel, exposing the surface, damage floor steel The protective layer of the above causes the above problems: 1. The design requirements did not take into account the requirements for the use of the building and the height difference between the floors of the building, and they were not reflected in the structure.
