Double-end inserting elastic 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 of end board, two or more inflation draw crew caps which distribute circumferentially on the end board. The insert-style mesh alveolus locates in the inflation cavity of the inflation draw screw cap and there is a spring sets between the outside of the alveolus and the wall of the inflation draw screw cap. When face-to-face connected, the double-edged mesh rack inserted in the insert-style mesh alveolus and spring meshes with the inner teeth of the insert-style mesh alveolus by the role of the spring. The pre-make part is made of the double-edged insert-style spring mesh connection board and it has connection stake end-board with the inflation draw screw caps at both the two ends. Many items of the portrait reinforcing steel bar's two ends clip to the steel cap of the inflation draw screw caps respectively. The double-edged mesh rack is used to the face-to-face connection of two pre-make parts.

Description

Technical field: [0001] The invention relates to a pipe pile joint, a prefabricated plate joint, a bridge pier joint, a bridge joint, an electric pole interface and its prefabricated parts, and a pipe pile joint, a prefabricated plate joint, a bridge pier joint and a bridge joint. The pipe pile and the connection between the pipe pile and the pipe pile, the connection between the prefabricated slab and the prefabricated slab, the connection between the bridge pier and the bridge pier, the connection structure between the prefabricated pole and the prefabricated pole and the production of prefabricated parts The method belongs to the fields of prefabricated part fastening and prefabricated part manufacturing. Background technique: [0002] This application is based on the applicant's patent application number 200410091063.9 and the name "upper screw and lower top connection pile buckle and prefabricated parts". It consists of an expansion nut, an expansion screw and a top ten...

AI Technical Summary

Problems solved by technology

The fly in the ointment is: first, before docking, the expansion screw needs to be screwed into the screw thread of the expansion nut, and then the butt connection can be realized, so the speed of butt connection is slow; The structure is different, so its manufacturing mold and process are complicated, and the processing cost is high
