整体预应力板柱建筑的结构特点是:当整层的非预应力楼板吊装就位后(由设置在柱上的临时支托支承),在房屋的纵横两个方向上,对预先穿好的高强钢丝来施加预应力,这样逐层进行,使之形成整体空间结构。依靠预应力连结起来的板柱节点称作摩擦节点。在这里,预应力不仅是承重手段,同时又是装配手段。这种 The structural characteristics of the overall prestressed slab column building are: when the entire layer of non-prestressed slab is lifted into place (supported by a temporary support placed on the column), it is pre-applied in both the vertical and horizontal directions of the house. High-strength steel wire is used to apply prestresses, which are carried out layer by layer to form an overall spatial structure. The plate-column nodes connected by prestress are called friction nodes. Here, prestressing is not only a means of bearing but also an assembly method. This kind
