2. Description of the Related Art A conventional connector for a pipe deforming portion of a vinyl greenhouse is arranged so that both sides of the retaining portion of the connector body are aligned with the outer circumference of the maximum width of the bulging portion of the pipe. It was formed straight from one end to the other mouth end. Further, when the connector main body was attached to the bulging portion of the round pipe, no means was taken to confirm whether the connector main body was attached to the central position of the bulging portion.

[0003]

When making a polygonal gate-shaped roofing material for a vinyl greenhouse, one round pipe is pressed and bent at several points to make a polygonal gate-shaped roofing material, or a short round pipe. A polygonal gate-shaped roofing material is manufactured by connecting short pipes to both ends of a connecting pipe whose center portion is bent by bending. Then, the pressed and bent portion of the pipe is crushed and bulged portions are formed and deformed on both sides of the outer peripheral surface. Also, when a straight round pipe is pressed, a bulge portion is also formed.

When connecting a girder pipe orthogonally to the gate-shaped roofing material, a connecting tool is attached to the bulging portion of the pipe to connect the girder pipe. In the conventional connecting tool, the connecting tool body is held. Since both sides of the portion are formed straight from one mouth end of the holding portion to the other mouth end in accordance with the outer circumference of the maximum width portion of the bulging portion of the pipe, when the connecting tool is attached, the connecting tool Since the mouth end portion of the holding portion of the main body has a large step between the outer peripheral surface of the true circle of the pipe and a gap is formed, the mouth end portion and the pipe do not match.

When the vinyl sheet is covered after the connecting tool and the girder pipe are connected to the gate-shaped roofing material, the vinyl sheet is formed due to the existence of the gap between the pipe and both ends of the holding portion of the connecting tool body. Is caught in the mouth end of the holding part and damaged.

Further, if both sides of the holding portion of the connector main body are formed straight from one mouth end portion to the other mouth end portion in accordance with the outer circumference of the maximum width portion of the bulging portion of the pipe, After installation, the connecting tool often staggered in the extension direction of the pipe. This is particularly remarkable when the pipe is a straight pipe.

Further, when attaching the connector main body to the bulging portion of the pipe, it is difficult to match the central portion of the connector main body with the central position of the bulging portion, and it takes time to confirm the attaching position, and the attaching position If they are misaligned, the connectors will be easily misaligned after mounting.

In view of the above points, the present invention prevents the vinyl sheet from being damaged at the mouth end of the holding portion of the connector body, and swells when the connector body is attached to the bulging portion of the pipe. An object of the present invention is to provide a connector for a deformed portion of a pipe of a vinyl house, in which the center position of the portion can be confirmed, and after the connector body is attached, it does not shift in the extension direction of the pipe due to vibration or the like.

In order to solve the above-mentioned problems, the connector according to the present invention is provided with a bulging portion in which a round pipe is partially crushed and bulging portions are formed on both sides of the outer peripheral surface to be deformed. A hugging part of an inverted U-shaped plate body, which is a pipe connector that is attached and that connects the round pipe and a pipe orthogonal thereto, and in which a hug part that hugs the bulging part is bent and formed in a central portion. The fitting recesses of the pipe orthogonal to the round pipe are formed in the lower portions of the wall surfaces on both sides of the fitting recess, and the wedge engaging bending pieces are provided at the lower ends of the wall surfaces on both sides of the fitting recess toward the upper inside. A wedge is driven between the lower surface of the pipe orthogonal to the round pipe and the wedge engaging bent piece, and in the connector for connecting the round pipe and the pipe orthogonal thereto, the holding portion is Except for both ends, the bulging parts on both sides fit to the outer peripheral surface of the bulging part of the round pipe. Together they are made, both openings ends of the holding portion is characterized in that it is formed to fit the outer circumferential surface of the perfect circle of the round pipe.

Further, a laterally long window hole can be provided on the wall surface above the fitting recess so that the central position, which is the maximum width of the bulging portion of the round pipe, can be confirmed. Further, it is preferable that the upper surface of the holding portion is bulged in an arc shape over the entire length from one mouth end portion to the other mouth end portion.

According to the present invention having the above-mentioned structure, both sides of the holding portion are bulged so as to fit the outer peripheral surface of the bulging portion of the round pipe except for the both ends of the holding portion, and the both ends of the holding portion are bulged. Since the part is formed to fit the outer circumference of a perfect circle of a round pipe,
When the connecting tool is attached, both mouth ends of the holding portion are matched with the outer peripheral surface of the perfect circle of the pipe and no gap is formed, so that the vinyl sheet is prevented from being caught by the mouth end and damaged.

Further, if both ends of the holding portion are formed so as to fit to the outer peripheral surface of a perfect circle of the pipe, when the connecting device is attached, the connecting device is extended in the extending direction of the pipe due to vibration or the like. Even if it tries to shift, the mouth end of the holding portion is caught by the bulging portion of the pipe, and the shift is prevented.

Further, since the window hole is provided on the wall surface above the fitting recess of the connector, it is possible to confirm the central position, which is the maximum width of the bulging portion of the pipe, by the window hole when the connector is attached. It will be possible. Also, if the upper surface of the holding portion is bulged in an arc shape over the entire length from one mouth end to the other mouth end,
It can also be used for a bent portion of a pipe having an ordinary perfect bent portion in which no bulging portion is formed.
