建筑工程主体结构检查验收时,经常发现楼板侧压墙的现象,这样安装楼板,不但不符合原设计要求,而且是错误的。预应力楼板是两对边简支的单向板。所谓两对边简支的单向板,一般是指楼板两端部支承在墙或梁上,跨度方向可以自由下垂产生挠度的板。普通预应力楼板,一般都是单向板,钢筋在板中的配置和截面的选型都是按单方向受力考虑的。因此,安装时也必须符合原设计要
When the main structure of a building project is inspected and accepted, it is often found that the floor presses on the side wall. This way of installing the floor slab is not only inconsistent with the original design requirements, but it is also wrong. Prestressed slabs are unidirectional panels that are simply supported by two pairs of sides. The so-called two-sided and simply supported unidirectional plates generally refer to plates whose two ends of the floor are supported on a wall or a beam, and whose span can be freely sagged. Ordinary prestressed floor slabs are generally one-way slabs. The configuration of the steel bars in the slab and the selection of sections are considered in one direction. Therefore, the installation must also meet the original design
