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-ended expansion engaging body pile buckle is composed of two expansion nuts 1, the double-ended expansion engaging body 3 and the expansion pin 2. When docking, the expansion body of the double-end expansion engaging body 3 expands in the In the expansion chamber 6 in the two expansion nuts 1 and expand and engage with the meshing teeth on the wall of the expansion chamber, see the attached 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, and the expansion engagement cav...

Embodiment 2

[0018] Embodiment 2: with reference to attached Image 6 . On the basis of Example 1, the prefabricated parts (pipe piles----round tubular, square pipe piles, etc.) composed of double-headed expansion meshing body buckles, the two ends of the prefabricated parts 10 are respectively equipped with expansion nuts 1 , the upsetting heads 11 at both ends of several longitudinal steel bars in the prefabricated part 10 are respectively clamped on the steel bar upsetting head clamping table 5 in the expansion nut 1, and the double-headed expansion engaging body 3 and the expansion pin 2 are used for two prefabricated parts 10 butts. (when the double-ended expansion body 3 is docked with the pipe pile, the expansion body in the double-ended expansion body expands in the tension nut 1; when the pipe pile and the pipe pile are not docked, the double-ended expansion body 3 and the Pull the nut 1 to separate and keep it separately).

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 a double-ended expansion engaging body pile connection, the two to be docked The ends of the prefabricated parts are respectively provided with several expansion nut openings and the openings of the expansion nuts are opposite to each other. The double-ended expansion engagement bodies are respectively expanded in the expansion chambers of the expansion nuts through the expansion pins to complete the gap between the prefabricated parts and the prefabricated parts. docking.

Abstract

The invention relates to a pipe pile joint, a prefabricated part formed by the interface of the prefabricated part, a connection structure between the prefabricated part and a prefabricated part manufacturing method, and belongs to the field of prefabricated part buckle and prefabricated part manufacturing. The double-ended expansion engagement body pile buckle is composed of two expansion nuts, double-end expansion engagement body and expansion pin. The expansion chamber in the cap is in expansion engagement with the engagement teeth on the wall of the expansion chamber. The prefabricated part is composed of double-headed expansion meshing pile buckles. The two ends of the prefabricated part are respectively equipped with expansion nuts. On the head card table, the double-headed expansion engagement body and the expansion pin are used for the butt joint between the two prefabricated 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...
