Connecting structure of concrete rod parts of permeable frame

The invention provides a connecting structure of concrete rod parts of a permeable frame. The connecting structure comprises a connecting plate, bolts and nuts, wherein the connecting plates are used for enabling two matched concrete rod parts to be fixedly connected. Bolt connecting holes matched with the bolts are formed in the two ends of the connecting plate, and the bolts are welded to reinforcing steel bars inside the concrete rod parts and exposed out of the surfaces of the concrete rod parts. The positions of the bolts are determined according to the type of a double-point connecting part. Diameter of the bolts is selected according to the engineering strength requirement. In the mounting process, the bolts penetrate the bolt connecting holes, and are pre-tightened by the nuts, and connection is completed. The double-I-shaped permeable frame is twisted to be formed. Due to the fact that no welding points exist in the screw joint technology, durability of a permeable component is improved, and the service life of an engineering is greatly prolonged.
