Eleastic expansion meshing body pile connecting end plate and prefab

Abstract

The invention relates to tubular interface, the pre-make part, which is made of pre-make part's interface and the connection instruction between the pre-make parts as well as the facture of the pre-make part. It comprises end board, two or more inflation draw crew caps and the top draw screw cap which distribute circumferentially on the end board, and the screw part of inflation mesh screw connects convolutedly into the inflation draw crew cap. The mesh alveolus locates in the cavity of the top draw screw cap. The insert-style mesh alveolus locates in the inflation cavity of the top draw screw cap. There is a spring sets between the outside of the alveolus and the wall of the top draw screw cap. When they are face-to-face connected, the insert-style mesh alveolus locates in the inflation cavity of the top draw screw cap, the mesh tooth part of mesh screw inserted in the insert-style mesh alveolus of the insert-style top draw screw cap and meshes with the mesh teeth in the alveolus. The two ends of the pre-make part have end-stake with many inflation draw screw caps and the pre-make part with many top draw screw caps respectively. In the pre-make part, there are many items of the portrait reinforcing steel bar whose two ends clip to the steel cap of the inflation draw screw caps and the top draw screw cap respectively. The mesh screw is used to the face-to-face connection of two pre-make parts.
