Problems solved by technology

[0004] In the above scheme, the tension nut and the top tension nut are respectively connected to the longitudinal steel bars of the reinforcement cage of the pipe pile. Fasten the connection after pulling, and the tensioning is completed in the production process of the pipe pile, which has a defect. If the pile buckle is to be pre-embedded in other components without steel cages such as walls and cement blocks , and there is no tensioning equipment on site, this prefabricated component cannot be used normally.

Embodiment 1

[0020] Such as figure 1 As shown, an integrated bar with a connecting head includes a bar-shaped rod body 1, and a connecting head 2 is respectively fixed at both ends of the rod body 1, and the size of the two connecting heads 2 can be the same or different , said connecting head 2 has a hollow accommodating cavity 3 inside. The accommodating cavity 3 has an internal thread or a Morse taper. Preferably, the connecting head 2 is integrally formed with the rod body 1 .

[0021] Such as image 3 As shown, when the present invention is embedded in the prefabricated component 100, the two connecting heads 2 can be embedded in the prefabricated component 100 or exposed in the prefabricated component 100 at the same time, or one connecting head 2 can be exposed in the prefabricated component 100, and the other A connection head 2 is embedded in the prefabricated component 100 .

[0022] The rod body 1 has an air channel 4 connecting the two connecting heads 2 along the axial dir...

Embodiment 2

[0024] The structure of this embodiment is basically the same as that of Embodiment 1, except that the rod body 1 is provided with at least one enlarged portion 7 protruding outward along the radial direction of the rod body 1, and the enlarged portion 7 increases the axis of the rod body 1. to tensile capacity.

Abstract

The invention belongs to the technical field of construction and relates to an integrated bar with a connecting head. The technical problem of inconvenient use of the prior art is solved. It includes a bar-shaped rod body, a connecting head is respectively fixed at both ends of the rod body, and a hollow accommodating cavity is provided inside the connecting head. The bar material of the invention has strong adaptability and is suitable for different prefabricated components, and the fast connection between two prefabricated components can be realized by matching the connecting piece.

Description

technical field [0001] The invention belongs to the technical field of construction and relates to an integrated rod body with a connecting head. Background technique [0002] In the previous application of the applicant for the patented screw-on-bottom-top pile buckle and prefabricated part [authorized announcement number: CN100348803C], it is composed of a tension nut, a top tension nut and a longitudinal steel bar of the pipe pile located at both ends of the pipe pile. , the expansion nut and the top pull nut are internal thread structures, and the internal thread is a strong wire buckle. There is a steel bar hole in the center of the bottom of the cap. The periphery of the steel bar hole is a steel bar heading card platform. The upsetting head is clamped on the card table. The prestressed pipe pile splicing buckle is composed of an expansion nut, a top tension nut, a combined insert sleeve, an intermediate sleeve and a connecting rod, wherein the expansion tension nut a...
