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 joint pile buckle is composed of two expansion nuts 1, the double-headed expansion joint body 4 and the expansion pin 7. Under the action, the expansion is hooked in the expansion hooking cavity 11 of the two expansion nuts 1 and is articulated with the boss 8 in the cavity. Have steel bar hole 9, the periphery of steel bar hole is steel bar upsetting card platform 2, and the space between card platform and strong drawing buckle is expansion joint chamber 11, sees 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. One or two or more expansion guide wire grooves are longitudinally opened on the wall of the guide channel of the expansion joint body of the double-ended expansion joint ...

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-ended expansion articulated pile buckles, the two ends of the prefabricated part 12 are respectively equipped with expansion nuts 1 , the upsetting heads 10 at both ends of several longitudinal steel bars in the prefabricated part 12 are respectively clamped on the steel bar upsetting card table 2 in the expansion nut 1, and the double-headed expansion joint body 4 and the expansion pin 7 are used for two prefabricated steel bars. Butt between pieces 12. (When the double-headed expansion joint body 4 is docked with the pipe pile, the expansion joint body in the double-headed expansion joint body expands in the expansion nut 1; when the pipe pile is not docked with the pipe pile, its The double-ended expansion joint body 4 is separated from the tension nut 1 and kept separately).

Embodiment 3

[0019] Embodiment 3: with reference to attached Figure 7 . On the basis of Embodiments 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 formed by the double-headed expansion articulated pile buckle, the two to be docked The ends of the prefabricated parts are respectively equipped with a number of expansion nuts, and the expansion nuts are clamped with the upsetting heads at both ends of the longitudinal reinforcement in the steel cage in the prefabricated part. Pull the cavity of the nut to complete the butt joint between 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. The double-edged inflation hang connection stake interface comprises two inflation draw screw caps, double-edged inflation hang-connection body and inflation pin. When face-to-face connected, the inflation hang-connection body inflates and hang connects to the cavities of the inflation hang-connection which are in two inflation draw screw caps, and hang connects to the bulgy stage. The pre-make part is made of the double-edged inflation hang connection stake interface, and it has the connection stake end-board with the inflation draw screw caps at both the two ends. 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 respectively. The double-edged inflation hang-connection 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...
