Description

Technical Field

[0001] The utility model relates to the field of pipeline accessories, in particular to a reinforcement device used for right-angle joints of pipelines. Background Art

[0002] When arranging pipes, right-angle connections are required, such as welding the vertical pipe vertically to the side of the horizontal pipe, and drilling holes on the side of the horizontal pipe to connect the horizontal pipe with the vertical pipe. However, the stability of the right-angle joints of the pipes connected in this way is general. When the vertical pipe is subjected to a large lateral force, it is easy to cause lateral shear force at the right-angle joint, resulting in fracture of the connection. Therefore, it is necessary to add a reinforcement device to the right-angle joint of the pipe to improve the stability of the right-angle joint of the pipe.

[0003] There is also a right-angle connection method as described in Chinese patent CN220567516U: a tee is used as a connecting structure at the right-angle joint position, and the tee as a connecting structure will produce three welding positions. Due to the increase in the number of welding positions, the overall stability will inevitably be weaker than that of a single welding position. Therefore, even if a tee is used, it is difficult to increase the stability of the right-angle joint. Therefore, there is an urgent need for a reinforcement device for the right-angle joint of a pipeline to improve the strength of the right-angle joint. Utility Model Content
