整体预应力装配式板柱结构(以下简称“板柱结构”)要求大楼板双向受力、四角点支承。因此,大楼板最好采用双向带肋板,若采用圆孔板,圆孔板单向受力、两端线支承,则圆孔板四边及四角要加强,成为非标准圆孔板构件。板柱结构中已有的大楼板的权型有以下五种:①下开口的带肋楼板;②采用填芯法生产上下均有板面的带肋楼板;③下开口带肋楼板复合底面板;④箱形带助楼板;⑤四边四角加强的圆孔板。以上五种型式大楼板在用于住宅时都不十分理想。其中,第一种型式必须后吊顶,造价高,只能
The overall prestressed assembled plate column structure (hereinafter referred to as “plate column structure”) requires that the building plate be supported in two directions and supported at four corners. Therefore, the building board is preferably made of bidirectional ribbed plates. If a circular hole plate is used and the circular hole plate is supported in one direction and supported at both ends, the four sides and the four corners of the circular hole plate must be strengthened to become non-standard round hole plate members. There are five types of weights for the existing building slabs in the slab structure: 1 ribbed floors with openings; 2 ribbed floors with slabs on the top and bottom; and 3 bottom ribbed floors with composite bottom panels. ;4 boxes to help the floor; 5 four-cornered round hole plate. The above five types of building boards are not ideal for residential use. Among them, the first type must be suspended from the ceiling, the cost is high, only
