Description

The interfacing part of a kind of use axial star annulus plate docking steel pipe
Technical field
The utility model relates to connector of steel tube, is specifically related to the interfacing part of a kind of use axial star annulus plate docking steel pipe.
Background technique
The normally used type axially connected between current steel pipe has:
(1) solder type: first respectively open a slope mouth at two steel pipe joints, then weld;
(2) Flange joint type: first respectively weld a flange plate at the joint of two steel pipes, then carries out high-strength spiral shell bolt and connects.
The advantage of solder type is that structural integrity is good, and shortcoming is that welding quality controls large to the dependence of operator's technical merit and exists and bring out potential safety hazard; The advantage of Flange joint type is that of avoiding the shortcoming of solder type, but also has the shortcoming of self simultaneously: flange plate diameter is larger than steel pipe, and the projecting edge of the large-size of formation can affect the layout of other rod members and the attractive in appearance of structure.
Model utility content
The technical problems to be solved in the utility model is, overcomes deficiency of the prior art, provides a kind of use axial star annulus plate to dock the interfacing part of steel pipe.
For technical solution problem, solution of the present utility model is:
Interfacing part with axial star annulus plate docking steel pipe is provided,
The interfacing part of a kind of use axial star annulus plate docking steel pipe, comprise the first steel pipe, the second steel pipe and star annulus plate, described star annulus plate is hollow structure, and in establish five pieces of plate bars be interconnected in star, the butt end of described first steel pipe and the second steel pipe has axial spider fin, and five pieces of plate bars at the two ends of described star annulus plate respectively corresponding first steel pipe that embeds are fixedly connected with in the axial spider fin of the second steel pipe.
Improve as one, between the adjacent insert plates bar of described star annulus plate, angle is 72 °.
Improve as one, the internal diameter of described star annulus plate is greater than the external diameter of the first steel pipe and the second steel pipe.
Improve as one, the plate bar thickness of described star annulus plate is equal with the pipe thickness of the first steel pipe, the second steel pipe.
Improve as one, the degree of depth of the axial spider fin of described first steel pipe and the second steel pipe is greater than 1/2 of star annulus plate length.
Improve as one, the radial cross section of described first steel pipe, the second steel pipe is circular or regular polygon.
Compared with prior art, the beneficial effects of the utility model are:
1, two steel pipes of the present utility model are formed by star annulus plate docking pattern and are rigidly connected, power transmission is effective, working procedure is simple, the in-site installation welding of steel pipe, not only construction install convenience, and broken away from the dependence of quality of connection by welder's technical merit, welding working method can avoid disaster hidden-trouble;
2, widely applicable, star annulus plate docking pattern both can be used for coaxial connection, also can be used for becoming axle and connected, not only connect for section steel pipe of the same race, and the axis that also can be used between the dissimilar steel pipes such as external diameter, sectional shape, wall thickness connects.

Reference character: 1, the first steel pipe, the 2, second steel pipe, 3, star annulus plate, 4, plate bar, 5, spider fin.
Embodiment
Following embodiment can make the technician of this professional skill field more fully understand the utility model, but limits the utility model never in any form.
The utility model is the interfacing part of a kind of use axial star annulus plate docking steel pipe, comprise the first steel pipe 1, second steel pipe 2 and star annulus plate 3, described star annulus plate 3 is in hollow structure, and in establish five pieces of plate bars 4 be interconnected in star, the butt end of described first steel pipe 1 and the second steel pipe 2 has axial spider fin 5, and five pieces of plate bars 4 at the two ends of described star annulus plate 3 respectively corresponding first steel pipe 1 that embeds are fixedly connected with in the axial spider fin 5 of the second steel pipe 2.
The butt end of described first steel pipe 1 and the second steel pipe 2 is also at least connected in series a middle steel pipe, in the middle of each root, the butt end, two ends of steel pipe has axial spider fin, and in the middle of being embedded one end of star annulus plate 3 respectively, steel pipe two end axles is affixed in spider fin 5; One piece does not embed middle steel shaft and is fixedly connected into one to one end of the one end of star annulus plate 3 in spider fin 5 and the axial spider fin 3 of last steel pipe, and the radial cross section of described steel pipe be circle.
Wherein, between the adjacent insert plates bar of described star annulus plate, angle is 72 °, the internal diameter of described star annulus plate is greater than the external diameter of the first steel pipe and the second steel pipe, the plate bar thickness of described star annulus plate is equal with the pipe thickness of the first steel pipe, the second steel pipe, and the degree of depth of the axial spider fin of described first steel pipe and the second steel pipe is greater than 1/2 of star annulus plate length.
By that analogy, the axis docking of many steel pipes can be realized with above same method and step.
Therefore, actual range of the present utility model not only comprises the disclosed embodiments, be also included under claims implement or perform all equivalents of the present utility model.
