The standard span is 3-6 meters, with 0.3 meters as the grade difference, a total of 11 types. The standard width of the single-rib slab is 0.6 meters, and the standard width of the double-rib slab is 1.2 meters. When the span is less than 4.2 meters, no support is required. For spans above 4.2 meters, simple supports must be installed in the middle of the span.The prestressed tendons are made of prestressed spiral rib steel wire (1570MPa), the distributed tendons are made of HRB400, and the C40 dry hard concrete is used for extrusion molding, which has high production efficiency. It can be applied to various public buildings, residences, factory storage and other scenes with a span of 3-6 meters.

Advantages：

High production efficiency and low cost.

Excellent structural performance, saving steel consumption.

The construction is convenient, there are no ribs on all sides, and supports are no needed for spans below 4.2 meters.

disadvantages：

On-site construction pipeline penetrating rib layout design is more complicated.

The area of a single slab is small and the lifting efficiency is low.

Achievements: The current successful application project cases of our company are: Zhongke Building Project,Fuling Greenland Qiuyuetai Residential Project, Fuling Central Hospital Project, Fuling Baisheng Town Public Service Center Project
