Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a steel pipe butt-joining device. Background Art

[0002] Construction refers to the production activities during the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations.

[0003] In traditional construction, many steel pipes are cut into two or more sections for use. Some of the steel pipes are too short and no longer suitable for use. They become discarded steel pipes and are sold cheaply as construction waste. This situation is very common in construction. After a project is completed, a large number of discarded steel pipes are often generated, resulting in a serious waste of steel pipe resources and costs. Chinese patent CN208034022U discloses a pipe-to-pipe-to-pipe-to-pipe connection device for large-diameter steel pipes, including a first steel pipe and a second steel pipe, wherein a fixing seat is fixed on the top of the first steel pipe. The fixing seat is fixed on the top of the first steel pipe. The fixed seat is connected to the fixed end of the lifting arm through a bolt pin. The cantilever end of the lifting arm is located at the top of the second steel pipe. The cantilever end of the lifting arm is evenly spaced with a plurality of mounting holes, which are used to hang the first hand chain hoist. A lifting ear is fixed on the top of the second steel pipe, and the second hand chain hoist is installed at the fixed end of the lifting arm corresponding to the lifting ear. The lifting ear is provided with a pulling hole for connecting the second hand chain hoist and a lifting hole for connecting the first hand chain hoist. However, the device has the problem of unstable connection and the connection mechanism cannot be disassembled and recovered. Therefore, we propose a steel pipe butt-jointing device.
