Prestressed zigzag metal net concrete hollow slab and manufacturing method thereof
The invention provides a prestressed zigzag-form metal net concrete hollow slab and a manufacturing method thereof.The hollow slab comprises a zigzag-form metal net, concrete, prestressed steel bars, a steel bar welded net, a steel bar framework and an additional net, the zigzag-form metal net is a metal net which is bent up and down, and a cavity part is defined by the zigzag-form metal net and the additional net; during manufacturing, the zigzag-shaped metal net is used as a base body, lower-layer concrete is poured on a pedestal for producing a pre-tensioned prestressed concrete member in a factory, then the zigzag-shaped metal net is placed at the position of the base body in the tensioning pedestal and pressed into the lower-layer concrete, then the prestressed tendons are placed, tensioning operation is conducted, and the steel bar welded net is placed. And concrete in the receiving groove and concrete of the laminated layer are poured, and after the concrete strength reaches 80% through curing, the prestressed steel bars are loosened, cut off, hoisted out and put in storage. The invention has the characteristics of simple manufacturing, convenient installation, reasonable structure, reliable quality and wide application, and is suitable for industrial and assembly development.
本发明提供了一种预应力折形金属网混凝土空心板及其制造方法，该空心板包括折形金属网、混凝土、预应力钢筋、钢筋焊接网、钢筋骨架和附加网，折形金属网为上下弯折状的金属网，折形金属网和附加网围合形成空腔部；制造时，以折形金属网作为基体，先在工厂生产先张预应力混凝土构件的台座上，浇筑下层混凝土，再将折形金属网安放在张拉台座内基体的位置并压入下层混凝土内，再安放预应力筋并进行张拉作业，安放钢筋焊接网，浇筑承接槽内混凝土和叠合层混凝土，经养护、混凝土强度达到80％后，放松预应力钢筋，切断、吊出、入库。本发明具有制造简单、安装便捷、结构合理、质量可靠、用途广泛的特点，适合工业化、装配化发展。
