无梁板是将板直接支承在墙和柱上,不设置梁的板。
平板是指既无柱支承,又非现浇梁板结构,而周边直接由墙来支承的现浇钢砼板。通常这种板多用于较小跨度的文章,如建筑中的浴室、卫生间、走廊等跨度在3m以内,板厚60-80mm的板。
平板与无梁板的区别就是支承支座不同,平板由墙支承,无梁板由墙和柱来支承。
板式楼板是将楼板现浇成一块平板,四周直接支承在墙上,这种楼板称为板式楼板。板式楼板的底面平整,便于支模施工,但当楼板跨度大时,需增加楼板的厚度,耗费材料较多,所以板式楼板适用于平面尺寸较小的房间,如厨房、卫生间及走廊等,还具体可分为单向和双向板。
无梁楼板是在楼板跨中设置柱子来减小板跨,不设梁的楼板在柱与楼板连接处,柱顶构造分为有柱帽和无柱帽两种。当楼面荷载较小时,采用无柱帽的形式;当楼面荷载较大时,为提高板的承载能力、刚度和抗冲切能力,可以在柱顶设置柱帽和托板来减小板跨、增加柱对板的支托面积。无梁楼板的柱间距宜为6m,成方形布置。由于板的跨度较大,故板厚不宜小于150mm,一般为160~200mm。无梁楼板的板底平整,室内净空高度大,采光、通风条件好,便于采用工业化的施工方式,适用于楼面荷载较大的公共建筑(如商店、仓库、展览馆等)和多层工业厂房。
