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 ends are inserted into the pile end plate of the expansion engagement body, which includes an end plate 12, two or more expansion nuts 1 are distributed (welded) on the end plate 12, and the expansion engagement tooth sleeve 13 is located at the top of the expansion nut 1. In the expansion cavity 6, when docking, the expansion body of the double-ended expansion engagement body 3 is expanded and engaged in the expansion engagement tooth sleeve 13 in the expansion nut 1 under the action of the expansion pin 2, 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 opening of the expansion nut 1 is a strong wire buckle 7, and the center of the bottom of the cap is provided with...

Embodiment 2

[0018] Embodiment 2: with reference to attached Figure 6 . On the basis of Embodiment 1, the prefabricated part (pipe pile---round tubular, square pipe pile, etc.) composed of double ends inserted into the pile end plate of the expansion meshing body, the two ends of the prefabricated part 10 are respectively equipped with multiple The piling end plate 12 of a stretching nut 1, the headers 11 at both ends of several longitudinal steel bars in the prefabricated part 10 are respectively clamped on the steel bar heading clamping table 5 in the stretching nut 1, and the double ends are expanded and meshed. Body 3 is used for butt joint between two preforms. The expansion of the double-ended expansion engagement body 4 is in the expansion engagement tooth sleeve in the tension nut 1 . (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 no...

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 formed by inserting the double ends into the expansion engagement body pile connection end plate, the butt joint The ends of the two prefabricated parts are respectively equipped with pile connection end plates with a plurality of tension nuts. The openings of the pulling nuts are opposite, and the double-headed expansion engagement bodies are respectively expanded in the expansion engagement tooth sleeves in the expansion nuts through the expansion pins to complete the butt joint between the prefabricated parts and the 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. The inflation mesh alveolus locates at the inflation cavity of the top draw screw cap. When they are face to face connected, the inflation part of double-edged inflation mesh inflates mesh in the mesh alveolus of the top draw screw cap 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 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...
