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

Embodiment 1

[0017] Embodiment 1: with reference to attached Figure 1-5 . The double-headed expansion engaging body piling end plate includes an end plate 12, and two or more expansion nuts 1 are distributed (welded) on the end plate 12. When docking, the expansion body of the double-headed expansion engaging body 3 is in the Under the action of the expansion pin 2, it expands in the expansion cavity 6 in the expansion nut 1 and expands and engages with the meshing teeth on the wall of the expansion cavity. figure 1 . Tension nut 1 adopts metal (as steel, stainless steel, alloy steel etc.) or non-metallic material (as plastics, synthetic plastics, pottery etc.) to make by existing casting or injection molding or pottery firing or machining technology. The inner side of the cap opening of the expansion nut 1 is a strong wire buckle 7, and the center of the bottom of the cap is provided with a steel bar hole 4, and the periphery of the steel bar hole is a steel bar heading card platform 5...

Embodiment 2

[0018] Embodiment 2: with reference to attached Figure 6 . On the basis of Embodiment 1, the prefabricated parts (pipe piles----circular tubular, square pipe piles, etc.) composed of double-headed expansion meshing body pile end plates, the two ends of the prefabricated part 10 are respectively equipped with expansion and pulling The piling end plate 12 of the nut 1, the upsetting heads 11 of the two ends of several longitudinal steel bars in the prefabricated part 10 are respectively clamped on the steel bar upsetting head clamping platform 5 in the expansion nut 1, and the double-headed expansion engagement body 3 and Expansion pin 2 is used for the docking between two prefabricated parts 10 . (When the double-headed expansion body 3 is docked with the pipe pile, the expansion body in the double-headed expansion body expands in the expansion nut 1 and engages with it; when the pipe pile and the pipe pile are not docked, its double-headed expansion Body 3 is separated from...

Embodiment 3

[0019] Embodiment 3: with reference to attached Figure 7 . On the basis of Examples 1 and 2, the pile connection structure between the pipe pile and the pipe pile, or between the bridge pier and the bridge pier, or between the utility pole and the utility pole, which is composed of the pile connection end plate of the double-ended expansion meshing body, the two to be docked The ends of each prefabricated part are respectively equipped with a plurality of tension nuts with end plates, the mouth of the tension nut at the end of one prefabricated part is opposite to the mouth of the tension nut at the end of the other prefabricated part, double-headed expansion The engaging bodies are respectively expanded in the expansion cavity of the expansion nut through expansion pins and engaged with the teeth on the wall of the expansion cavity to complete the butt joint between prefabricated parts and prefabricated parts.

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 which distribute circumferentially on the end board. When connection, the inflation body of the double-edged inflation mesh body inflates in the inflation cavities of the inflation draw screw caps and inflate mesh with the mesh gear in the inflation cavity wall by the role of the inflation pin. The pre-make part is made of the double-edged inflation mesh body and it has the 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 inflation mesh body and the inflation pin are 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...
