Prestress fabricated roof board
The invention provides a prestress fabricated roof board including two longitudinal ribs, two horizontal ribs, a steel wire mesh, a board concrete layer, a plurality of prestress assemblies, and a steel stranded wire. The longitudinal ribs are arranged in a parallel mode at intervals; the horizontal ribs are arranged in a parallel mode at intervals, and the top faces of the longitudinal ribs and the horizontal ribs are fixedly connected to surround a support framework with a rectangular horizontal section; the steel wire mesh is fixedly arranged on the top face of the support framework in a covering mode; the board concrete layer is arranged on the steel wire mesh, and a bottom face shape of the board concrete layer is matched with a top face shape of the support framework; the prestress assemblies are arranged on the lower surfaces of the longitudinal ribs at intervals along extending directions of the longitudinal ribs, and a stranded wire hole is formed in each prestress assembly; and the steel stranded wires penetrate through the stranded wire holes of the prestress assemblies successively, and two ends of the steel stranded wires are fixedly connected with the prestress assemblies located at two ends of the longitudinal ribs respectively. The roof board has the beneficial effects that the weight of the prestress fabricated roof board can be lightened under the premise of guaranteeing whole strength, so that the roof board has the advantages that durability is high, the weight is light, and the manufacturing is convenient.
本发明提供了一种预应力装配式屋面板，包括：两个纵肋，平行间隔设置；两个横肋，平行间隔设置，两个横肋与两个纵肋的顶面固定连接以围成一水平截面为矩形的支撑框架；钢丝网，固定盖设在支撑框架的顶面；板面混凝土层，设置在钢丝网上，且板面混凝土层的底面形状与支撑框架的顶面形状相适配；多个预应力组件，沿纵肋的延伸方向间隔设置在纵肋的下表面，每个预应力组件均设置有绞线孔；钢绞线，依次穿过多个预应力组件的绞线孔，且钢绞线的两端分别与位于纵肋两端的预应力组件固定连接。本发明的有益效果是，可以在保证整体强度的前提下，减轻预应力装配式屋面板的重量，使本发明具有耐久性高，重量轻，制作方便的优点。
