Description

Technical Field

[0002] Steel pipes are mainly used in the construction of housing, tunnels, water conservancy, chemical industry, coal, national defense and other projects. Steel pipe racks are often used for construction. They have hollow cross-sections and their length is greater than their diameter or circumference. They are divided into round, square, rectangular and special-shaped steel pipes according to their cross-sectional shape.

[0003] In order to improve the installation stability between steel pipes, in the prior art, steel pipes are generally installed by fixed welding or screws. These connection methods are cumbersome to operate, troublesome to construct, low in installation efficiency, and time-consuming and labor-intensive.

A rubber sleeve is provided on the sliding sleeve of the steel pipe A, and a clamping mechanism is provided on the sleeve. The clamping mechanism includes a mounting block fixedly mounted on the sleeve, and arc-shaped clamping rings A and arc-shaped clamping rings B are rotatably mounted on both sides of the mounting block, and a fixing component is provided between the ends of the clamping rings A and B. The clamping mechanism is used to achieve quick installation between the steel pipe A and the steel pipe B, which is simple and convenient to set up, saves installation time, and thus improves installation efficiency; the alignment mechanism A or the alignment mechanism B is used to achieve alignment before fixing between the steel pipe A and the steel pipe B, so as to prevent misalignment between the steel pipe A and the steel pipe B, which affects the stability of the installation, and thus improves the practicality of the device.

[0005] As the existing devices are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0007] Second, after the upper cylindrical tube and the lower cylindrical tube are butt-jointed, axial displacement is likely to occur between the two cylindrical tubes, affecting the stability of the pipe rack support.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
