Abstract

The present invention relates to a device for fastening intersecting pipes, and more specifically, to a device for fastening intersecting pipes in which a fastening body, which is a contact member interposed between intersecting first and second pipes, has contact legs formed on both sides of the contact body to be closely supported on both sides in the longitudinal direction of each pipe, and a bending groove formed in the longitudinal direction of the pipe is provided on at least one of the two sides of the contact body, so that the contact body is pressed by a pressure bending motion toward the pipes centered on the bending groove by the pressure of a fastening member that simultaneously presses and fixes the contact member and the first and second pipes, thereby increasing the bonding force between the pipes.

Claims (5)

  1. In a cross-tube fastening device that interposes a sealing member (10) at the intersection between the first and second tube bodies (1, 2) and pressurizes and fixes the first and second tube bodies (1, 2) with a fastening member (20), The above-mentioned contact member (10) has a first contact leg (12a) formed by bending in the direction of one side of the contact body (11) to provide close support to both sides in the longitudinal direction of the first pipe body (1), and a second contact leg (12b) formed by bending in the direction of the other side of the contact body (11) to provide close support to both sides in the longitudinal direction of the second pipe body (2), A cross-tube body fastening device in which a groove-shaped bending groove (16) formed along the longitudinal direction of the tube is provided on at least one of the surfaces of the contact body (11) and the other surface, so that the contact body (11) is pressed against the tube by a pressure bending groove (16) centered on the fastening member (20), thereby increasing the bonding force between the tubes (1, 2).
  2. In paragraph 1, A cross-tube fastening device having a bending groove (16) formed in the longitudinal direction of the intersecting tubes and a contact leg (12) that is closely supported on both sides in the longitudinal direction of the first and second tubes (1, 2), and a C-shaped clip (14) that is elastically coupled to the tubes being closely connected on at least one side of the contact body (11), which is provided with a bending groove (16) formed in the longitudinal direction of the intersecting tubes and a contact leg (12) that is closely supported on both sides in the longitudinal direction of the first and second tubes (1, 2).
  3. In paragraph 1 or 2, The above-mentioned contact body (11) is formed with a corresponding shape part (11A) corresponding to the shape of the tube body (1,2) that contacts the intermediate part provided on one side and the other side along the longitudinal direction of the first and second tube bodies (1,2), and both sides of the corresponding shape part (11A) are formed as plate-shaped parts (11B), wherein the bending groove (16) is formed in the longitudinal direction of the first and second tube bodies (1,2) between the corresponding shape part (11A) and the plate-shaped part (11B), forming a cross tube body fastening device.
  4. In paragraph 3, The contact legs (12), formed to support the longitudinal sides of the first and second tube bodies (1, 2) respectively on one side and the other side of the contact body (11), are a cross tube body fastening device formed at the end of the plate-shaped part (11B).
  5. In paragraph 1 or 2, The above-mentioned contact body (11) is formed as a plate-shaped part (11B) in the form of a flat plate, and the above-mentioned bending groove (16) is formed in the longitudinal direction of the tube at the middle portion between one side and the other side of the contact body (11), forming a cross-tube body fastening device.

Description

Pipe cross fitting device for pipes The present invention relates to a device for fastening intersecting pipes, and more specifically, to a device for fastening intersecting pipes in which a fastening body, which is a contact member interposed between intersecting first and second pipes, has contact legs formed on both sides of the contact body to be closely supported on both sides in the longitudinal direction of each pipe, and a bending groove formed in the longitudinal direction of the pipe is provided on at least one of the two sides of the contact body, so that the contact body is pressed by a pressure bending motion toward the pipes centered on the bending groove by the pressure of a fastening member that simultaneously presses and fixes the contact member and the first and second pipes, thereby increasing the bonding force between the pipes. Generally, vinyl greenhouses used for horticulture, agriculture, livestock barns, or warehouses are constructed by connecting pipes for the frame. In such vinyl greenhouses, pressure pins, which are fastening members that apply pressure to intersecting pipes to secure them, are installed at the intersections of the pipes to ensure that the pipes serving as the frame are firmly connected. However, since each intersecting pipe is typically formed in a cylindrical shape, there is a problem in that the contact points between intersecting pipes are very limited, consisting only of point or linear contact. In addition to the pressure-fixing force of such conventional fastening members, recently, a sealing member is introduced between cylindrical intersecting tubular bodies to increase the sealing range between the tubular bodies and further improve the sealing force. For example, prior art in which a sealing member is interposed between intersecting pipes includes Korean registered patent No. 10-2635746 (registered on Feb. 6, 2024; pipe intersection fixing device for vinyl greenhouses), Korean published patent No. 10-2019-0109913 (published on Sep. 27, 2019; fixing device for the intersection of pipes), and Korean registered patent No. 10-1035640 (registered on May 12, 2011; fixing device for the intersection of pipes). All of the above prior art technologies involve a sealing member interposed between intersecting tubular bodies, wherein the tubular bodies are in contact with each other on both sides of a plate-shaped sealing body. At this time, in order to increase the sealing range between the sealing body and the tubular bodies, sealing legs are formed by bending each surface on one side and the other side of the sealing body. The configuration is such that the sealing legs formed by bending are in contact with the circumference of the tubular bodies. However, in the configurations of the prior art described above, there is a problem in that in order for the end of the contact leg to contact and adhere to the pipe, the diameter of the pipe and the bending length of the contact leg formed by bending in the contact body must be comprehensively calculated and applied in the design to secure the expected contact force and adhesion force between the contact member and each pipe, thereby increasing the bonding force between intersecting pipes. FIG. 1 is an exploded perspective view illustrating the usage state of a cross-tube fastening device according to one embodiment of the present invention. FIG. 2 is a combined perspective view of FIG. 1. FIG. 3 is a perspective view of a contact member according to an embodiment of the present invention. FIG. 4 is a conceptual diagram of the operating state of a cross-tube fastening device according to an embodiment of the present invention. FIG. 5 is a perspective view of a contact member according to another embodiment of the present invention. The present invention will be described in detail below using the attached drawings. However, since the attached drawings represent preferred embodiments of the present invention, the scope of the present invention is not limited by these drawings. Furthermore, even if a configuration is essential for implementing the present invention, specific descriptions of configurations that fall under known technology or that a person skilled in the art can easily implement from known technology are omitted. As shown in FIGS. 1 to 5, the present invention is characterized by a configuration in which a contact member (10) intervenes and is coupled between a first pipe body (1) and a second pipe body (2), and is pressed and bent toward the pipe bodies (1, 2) around a bending groove (16) formed in a contact body (11) by the pressure of a fastening member (20) that simultaneously presses and fixes the pipe bodies (1, 2) and the contact member (10), thereby increasing the coupling force between the pipe bodies (1, 2). The first tube (1) and the second tube (2) may be formed in a columnar or hollow pipe shape, and their cross-sections may be formed in a circular or polygonal shape, and their outer diamete
