Problems solved by technology

[0004] The above-mentioned background technology has a fly in the ointment: first, the strong tensile strength between the connectors cannot meet the requirements of the national standard; During the connection process, the threaded connection surface is easily damaged, and loses the function of blocking the tapered sleeve, resulting in failure of insertion; Fourth, the sealing problem of the connector is not well solved

Embodiment 1

[0015] Embodiment 1: with reference to attached Figure 1-3 . A prefabricated component connector, which includes a small nut 8, an insert rod 7, a medium-hole nut 6, and a large nut 2. There is a hole at the bottom of the large nut 2, and the steel rod 1 is stuck in it, and the spring 3 is located in the big nut 2 and one end of the spring 3 is in contact with the heading head, and the other end is in contact with the split collar 5. The middle hole nut 6 is screwed into the big nut 2, wherein the middle hole nut 6 The lower end is elastically matched with the split collar 5, and the brim of the middle hole nut 6 is clamped on the end face of the large nut 2; 5, the circular area of ​​the bottom of the plug 7-1 is greater than the circular area of ​​the plug neck 7-4 integrated with it and forms a ring plug neck 7-4 ring card platform 7-2; the plug body of the plug 7-1 7-5 is screwed with small nut 8.

[0016] One or more rings of annular bead 7-3 are formed on the insert ...

Embodiment 2

[0022] Embodiment 2: On the basis of Embodiment 1, a spacer 4 is provided between the spring 3 and the split collar 5, and the gasket 4 mainly supports the function of the split collar 5, which is convenient for the split collar 5 Install.

Embodiment 3

[0023] Embodiment 3: with reference to attached Figure 4 and 5. On the basis of Embodiment 1, the butt joint method of concrete prefabricated components composed of prefabricated component connectors, preparations before docking: Among the butt joint surfaces of the two concrete prefabricated components A and B to be butted, the butt joint surface ring of A concrete prefabricated components There are a plurality of large nuts 2 built into the surface, steel rods 1 are pierced in the holes at the bottom of the large nuts 2, the upsetting head of the steel rods 1 is stuck in the large nuts 2, the spring 3 is loaded into the large nuts 2 and one end of the spring 3 It is in contact with the heading head, and the other end is in contact with one side of the loaded split collar 5. The middle hole nut 6 is screwed into the large nut 2, and the lower end of the middle hole nut 6 is connected to the other side of the split collar 5. It is an elastic fit, and the brim of the middle-...

Abstract

The invention relates to a prefabricated member connector and a method for butting a concrete prefabricated member consisting of the same. The bottom of a large screw cap is provided with a hole, the upset head of a steel bar is blocked in the hole, a spring is positioned in the large screw cap, one end of the spring is contacted with the upset head, the other end of the spring is contacted with a split collar, and a medium hole screw cap is screwed into the large screw cap, wherein the lower end of the medium hole screw cap is elastically matched with the split collar, and the edge of the medium hole screw cap is blocked at the end face of the large screw cap; an insertion rod has an integrated structure consisting of an insertion head, an insertion neck and an insertion body, wherein the circle area of the bottom of the insertion head is greater than the diameter of the insertion neck integrated with the insertion head, and an annular insertion neck clamping table is formed at the bottom of the insertion head; and the insertion body of the insertion rod is screwed with a small screw cap. The invention has the advantages that: 1, the strong tensile strength among insertion pieces greatly exceeds the international standard; 2, breakage of butted pieces is radically solved; and 3, the sealing problem of the insertion pieces is thoroughly solved, the reliability of insertion and connection between the prefabricated members is ensured, and the reliability of a building foundation is ensured.

Description

technical field [0001] The invention relates to a high-strength butt joint connection between concrete prefabricated components and concrete prefabricated components, which can prevent the butt joint surface of the concrete prefabricated components from being stressed by the butt joint parts, and at the same time make the joint joint surfaces and the joint joint parts sealed and corrosion-free The invention relates to a prefabricated component connector and a method for butt jointing of a concrete prefabricated component composed of the prefabricated component connector, belonging to the field of concrete pile manufacture and butt joint. Background technique [0002] The applicant owns CN100348803C, titled "upper screw and lower top expansion engaging body pile buckle and prefabricated parts", the upper screw and lower top expansion engaging body pile buckle is composed of an expansion nut, an expansion engagement screw top tension nut and an expansion pin , the expansion nu...
