Abstract
Disclosed herein is a pipe joint for connecting pipes. The pipe joint comprises separate joint bodies, each of which has a pipe fixing portion comprising a plurality of diamond or pyramid-shaped protrusions formed on an inner surface thereof to provide a strong coupling force with respect to the pipes in order to prevent the pipes from being released from the pipe joint. Since conventional pipe joint provides a low coupling force, there is a disadvantage in that, when connecting stainless pipes, aluminum pipes or coated pipes using the pipe joint, these pipes can be easily separated from the pipe joint due to its low coupling force, causing many problems in assembly of construction. The present invention is designed to solve the problem of the conventional pipe joint, and provides an environmentally friendly pipe joint.
Description
Description
PIPE JOINT
Technical Field
[1] The present invention relates to a pipe joint for connecting pipes used for a pipe- connection type structure. More particularly, the present invention relates to a pipe joint for connecting pipes, which comprises separate joint bodies, each having a pipe fixing portion comprising a plurality of diamond or pyramid-shaped protrusions formed on an inner surface thereof to provide a strong coupling force with respect to the pipes in order to prevent the pipes from being released from the joint.
[2]
Background Art
[3] In general, a structure used for holding or transporting light products or enhancing activity in the field of construction is constructed using pipes (which will hereinafter be referred to as a pipe or pipes ) such as stainless pipes, aluminum pipes or coated pipes, and materials for such structures have joint structure in which, in a state of interposing a pipe or pipes therebetween, separate joint bodies are coupled by bolts and nuts at respective ends of the pipes facing each other or at an intermediate portion of the pipe in order to connect the pipes. Here, each of the separate joint bodies has a pipe receiving section, which has suitable dimension and shape to receive the pipe.
[4]
[5] Figs. 3 and 4 are an exploded perspective view and an assembled cross-sectional view of a conventional pipe joint used for connecting pipes which have a resin layer coated on their surface. In Figs. 3 and 4, each of the pipes 10 is coated with a resin layer 20, and is securely connected with another pipe by the pipe joint comprising separate joint bodies 30 in such a way that, when two separate joint bodies 30 are coupled by a bolt 40 and a nut 42, protrusions 32 circumferentially formed on each separate joint body 30 dig into the resin layer 20 on each pipe 10.
[6]
[7] In addition, Figs. 5 and 6 are an exploded perspective view and an assembled cross- sectional view of another conventional pipe joint used for connecting pipes which are machined on their surface. In Figs. 5 and 6, each of the pipes 30 has recesses 50 formed along an outer periphery of the pipe, and each of separate joint bodies 30 has protrusions 52 circumferentially formed thereon, so that, when the two separate joint bodies 30 are coupled by a bolt 40 and a nut 42, the recesses 50 of the pipes 10 securely engage with the protrusions 52 of the separate joint bodies 30.
[8]
[9] Although the pipe joint shown in Figs. 3 and 4 has been widely used due to its merits in that a post process such as plating or painting after connecting is not needed, it suffers from easy separation or damage of the resin layer after a long period of time. In addition, upon disuse of the pipes, since it is necessary to separate the resin layer coated on the pipe from the pipe by heating the resin layer, it requires cumbersome operation, and since the pipe is disused in a state of being coated with the resin layer, it is not environmentally friendly.
[10]
[11] Meanwhile, the pipe joint shown in Figs. 5 and 6 has a merit in that, since the resin layer is not coated on the surface of the pipes, this structure is environmentally friendly. However, this pipe joint has problems in that, since separate machining operations for forming the recesses on the pipes and the protrusions on the separate joint bodies are required, manufacturing costs are significantly increased, and that, if a user wants to recycle the pipes, it is necessary to form new recesses on the pipes. Accordingly, the pipe joint shown in Figs. 5 and 6 is low in its practical utility, and thus is not widely used.
[12]
[13] Thus, it has been needed to provide a simple and convenient pipe joint, which is environmentally friendly and easy in disuse or recycling thereof, and does not require additional machining operation except for the cutting of the pipes.
[14]

[15] The present invention has been made in view of the above problems, and it is an object of the present invention to provide a simple and convenient pipe joint, which is environmentally friendly and easy in disuse or recycling thereof, and does not require additional machining operation except for the cutting of the pipes. Technical Solution
[16] In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a pipe joint for connecting a plurality of pipes from upper, lower, left and right sides, the pipe joint comprising separate joint bodies coupled by a bolt and a nut at respective ends of the pipes facing each other or at an intermediate portion of one of the pipes in a state of being interposed between the separate joint bodies, wherein each of the separate joint bodies includes a pipe fixing portion comprising a plurality of diamond or pyramid-shaped protrusions formed on the surface.
[17] The plurality of diamond or pyramid-shaped protrusions may compress and slightly
dig into a surface of an associated pipe to prevent the pipe from being separated from the coupled joint bodies.
[18]
Advantageous Effects
[19] According to the present invention, since the pipe joint does not require additional machining operation except for the cutting of the pipes, and has the plurality of diamond or pyramid-shaped protrusions designed to provide a strong coupling force, it has low manufacturing cost, and remarkably enhances the endurance of a pipe- connected structure.
[20] In addition, the pipe joint of the invention increases recycling opportunity of the pipes without pollution, so that wide application of the pipe joint according to the invention is also environmentally friendly.
