  As shown in FIGS. 1 to 3, the connector 1 according to the embodiment of the present invention has a second portion extending in the second direction A2 in the middle of the pipe material P1 as the first rod-shaped body extending in the first direction A1. The tip part of the pipe material P2 as a rod-shaped body is butted and connected. The connector 1 includes a flat plate portion 10 extending in the third direction A3, a first semi-cylindrical portion 11 extending in the first direction A1, a second semi-cylindrical portion 12 extending in the second direction A2, and a third direction A3. It is a substantially L-shaped metal fitting having a third semi-cylindrical portion 13 extending in the direction.

  The first direction A1 and the second direction A2 are basically orthogonal to each other. However, when the plane formed by the first direction A1 and the second direction A2 is a horizontal plane, the second direction A2 is within the horizontal plane. It is good also as a direction which cross | intersects the 1st direction A1 diagonally. The third direction A3 is basically a direction perpendicular to the plane formed by the first direction A1 and the second direction A2, but may be a direction slightly rotated around the first direction A1. In addition, the connector 1 in this embodiment is used when connecting the pipe material P1 which makes the 1st direction A1 a horizontal direction fundamentally, and the pipe material P2 which makes the 2nd direction A2 the horizontal direction. The third direction will be described as the vertical direction with reference to the arrangement of the pipe materials P1, P2 at this time.

  The first semi-cylindrical portion 11 has a semi-cylindrical shape along the upper half surface (the outer peripheral surface above the central axis of the pipe material P1) of the pipe material P1, which is the first rod-shaped body. The “semi-cylindrical shape” does not strictly indicate a half of the cylinder, but indicates a part of the curved surface constituting the cylinder. The same applies to the following description.

  The flat plate portion 10 extends downward from the lower end portion 11B of the first semi-cylindrical portion 11 in the third direction A3, and is lower than the center 11A of the first semi-cylindrical portion 11 (see FIGS. 6 and 7). The substantially square hole 14 formed in the approximate center of this position. The flat plate portion 10 is easier to bend than the first to third semi-cylindrical portions 11 to 13 by forming the holes 14.

  The second semi-cylindrical portion 12 extends in the second direction A2 from the end portion 11C opposite to the lower end portion 11B of the first semi-cylindrical portion 11, and extends along the upper half surface of the pipe member P2 that is the second rod-shaped body. It has a semi-cylindrical shape. The third semi-cylindrical portion 13 extends downward from the lower end portion 11B of the flat plate portion 10, and has a semi-cylindrical shape that bends the flat plate portion 10 along the lower half surface of the pipe material P1 and follows the lower half surface of the pipe material P2.

At the time of being along, it has at least one pair of flange parts 15 and 16 for mutually fastening the 2nd semi-cylindrical part 12 and the 3rd semi-cylindrical part 13 in the position straddling pipe material P2.

  In one flange portion 15, a recess 15A that restrains the rotation of the bolt B corresponding to the two widths of the bolt B is formed at a position straddling the pipe P2. Further, a hole 15B through which the shaft portion of the bolt B passes is formed in each recess 15A. Further, the other flange portion 16 is formed with a hole 16B through which the shaft portion of the bolt B passes at a position straddling the pipe P2. The hole 16B is a long hole extending in the third direction A3.

  When connecting the connector 1 having the above-described configuration to the middle portion of the pipe member P1 extending in the horizontal direction arranged on the vertical surface such as the wife's face of the greenhouse, by connecting the end portion of the pipe member P2 extending in the horizontal direction, The first semi-cylindrical portion 11 and the second semi-cylindrical portion 12 are arranged along the upper half surface of the pipe material P1 and the upper half surface of the pipe material P2, respectively, and extend downward from the lower end portion 11B of the first semi-cylindrical portion 11. The flat plate portion 10 is bent along the lower half surface of the pipe material P1, and the third semi-cylindrical portion 13 is placed along the lower half surface of the pipe material P2. At this time, the flat plate portion 10 is easily bent due to the formation of the substantially square hole 14, and is easily bent along the lower half surface of the pipe material P1 to the third half surface of the pipe material P2. It is possible to make the cylindrical part 13 follow.

  Thereafter, the second semi-cylindrical portion 12 and the third semi-cylindrical portion 13 are fastened to each other at a position straddling the pipe material P2 by bolts B and nuts N using the holes 15B and 16B of the flange portions 15 and 16. Thus, the pipe material P1 and the pipe material P2 can be butted in a T shape and connected. And in this connector 1, since the substantially square hole 14 of the flat plate part 10 is formed in the approximate center of the position below the center of the 1st semi-cylindrical part 11, the angle | corner of this substantially square hole 14 is provided. The film material F is not rubbed by contact with the film material F, and the film material F is not torn.

  Moreover, in the connector 1 in this embodiment, the pipe material P2 is clamped by the second semi-cylindrical portion 12 and the third semi-cylindrical portion 13, and bolts are used by utilizing the holes 15B and 16B of the flange portions 15 and 16. Since it can be connected and fixed simply by tightening with B and nut N, it is possible to cope even when pipe materials P2 having different dimensions are used.

  The connector of the present invention is a plastic house constructed by assembling pipe materials, and a plurality of rod-like bodies such as when connecting other pipes at right angles to one another in the middle of one pipe and connecting them in a T shape. It is useful as a connector for connecting and connecting in the shape of a pipe, and in particular, the tip of a pipe material that also extends in the horizontal direction in the middle of the pipe material that extends in the horizontal direction that is arranged on a vertical surface such as the end face of a greenhouse It is suitable as a connector that is not torn even if the film material comes into contact when the parts are connected to each other.
